"Cabiralizumab clearly demonstrates clinical benefit in patients with PVNS, including reduction in tumor size and improvements in pain and functional status," said Helen Collins, M.D., Senior Vice President and Chief Medical Officer of Five Prime. "Our recent market research indicates that patients with PVNS have significant unmet needs, especially in alleviating the pain and functional impairment caused by this chronic joint disease. The encouraging safety and efficacy results support continued development of cabiralizumab for this condition for which there are no currently approved medical treatments. We plan to have discussions with regulatory authorities about a potential pivotal trial in this orphan indication."

This Phase 1/2 clinical trial is an open-label, dose escalation and dose expansion study designed to evaluate the pharmacokinetics (PK), pharmacodynamics (PD), safety, and efficacy of cabiralizumab in patients with PVNS. The protocol was amended to allow for continued treatment with cabiralizumab with asymptomatic creatine kinase (CK) elevations. After the amendment, 21 additional patients were enrolled between November 2016 and March 2017. The efficacy results included in the poster and summarized below include only the 11 patients treated prior to the protocol amendment.

Safety Results

PK and PD of cabiralizumab support dosing at 4 mg/kg every two weeks or less frequently
No dose-limiting toxicities (DLTs) were observed at doses up to 4mg/kg
Most frequently reported adverse events (AEs) of periorbital and eyelid edema, rash and pruritus are similar to AEs reported in other agents in this drug class
— 3 out of 11 patients enrolled prior to the protocol amendment discontinued drug due to asymptomatic laboratory elevations of CK
Efficacy Results

Cabiralizumab demonstrates clinical benefit in patients with PVNS at 4mg/kg every two weeks
— Most patients enrolled at the 4 mg/kg dose prior to the amendment experienced tumor reduction
— 5 out of 11 patients had a radiographic response (4 confirmed)
— Improvement in median Ogilvie-Harris composite score of pain and function was reported in both responders and non-responders (per RECIST v1.1 on MRI)
— 12 additional patients enrolled after the amendment were considered efficacy evaluable with evidence of early shrinkage in tumor, but it was too early to assess overall response as of the data cut-off date
About PVNS
PVNS is a rare, locally aggressive tumor of the synovium. It is characterized by local over-expression of CSF-1, which recruits macrophages into the joints, forming the non-malignant tumor mass. It is associated with high morbidity, and there are no approved therapies for the condition. Five Prime is conducting a Phase 1/2 clinical trial studying cabiralizumab as a treatment for PVNS.

About Cabiralizumab (FPA008)
Cabiralizumab is an investigational antibody that inhibits the CSF-1 receptor and has been shown in preclinical models to block the activation and survival of monocytes and macrophages. Inhibition of CSF1R in preclinical models of several cancers reduces the number of immunosuppressive tumor-associated macrophages (TAMs) in the tumor microenvironment, thereby facilitating an immune response against tumors. Cabiralizumab is currently in a Phase 1/2 clinical trial in pigmented villonodular synovitis (PVNS) and a Phase 1 clinical trial in oncology indications. Cabiralizumab is being developed under an exclusive worldwide license and collaboration agreement entered into with Bristol-Myers Squibb (BMS) in October 2015.

On June 4, 2017 Bristol-Myers Squibb Company (NYSE:BMY) reported results of an interim descriptive analysis from an ongoing National Cancer Institute (NCI) Phase 3 randomized study evaluating Yervoy (ipilimumab) 3 mg/kg and Yervoy 10 mg/kg in patients with stage III or resectable stage IV melanoma who are at high risk of recurrence following complete surgical resection (Press release, Bristol-Myers Squibb, JUN 4, 2017, View Source [SID1234519363]). In this unplanned analysis of relapse-free survival (RFS) in concurrently randomized patients between the two experimental arms RFS at three years was 56% (n=367) for Yervoy 3 mg/kg (95% CI: 0.50, 0.61) and 54% (n=406) for Yervoy 10 mg/kg (95% CI: 0.49, 0.60).

All-Cause Grade 3/4 adverse events (AEs) were experienced by 53% of patients in the Yervoy 3mg/kg arm (n=516) and 66% of patients in the Yervoy 10 mg/kg (n=503) arm. Treatment-related Grade 3/4 AEs were experienced by 37% and 57% of patients in the Yervoy 3mg/kg and 10 mg/kg arms, respectively. Treatment-related AEs led to discontinuation in 35% of patients taking Yervoy 3 mg/kg and 54% taking Yervoy 10 mg/kg. There were eight deaths in the Yervoy 10 mg/kg arm and two in the Yervoy 3 mg/kg arm that were considered at least possibly treatment-related. These data will be presented during an oral session today from 8:00 – 8:12 a.m. CT during the Melanoma/Skin Cancers session in the Arie Crown Theater at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting 2017.

"Adjuvant therapy with ipilimumab represents an important option for appropriate stage III melanoma patients following complete resection who have a significant risk of disease recurrence; however, management of adverse events is essential to help ensure that appropriate patients are able to benefit from treatment," said Ahmad A. Tarhini, MD, PhD, University of Pittsburgh Cancer Institute. "These data are important because they advance our understanding of the benefits and risks of ipilimumab in the adjuvant setting."

"There is a need for safe and effective treatment options for melanoma patients after surgery who are at high-risk of relapse, only about half of whom receive treatment," said Vicki Goodman, M.D., development lead, Melanoma and Genitourinary Cancers, Bristol-Myers Squibb. "This analysis provides valuable information that may help inform treatment decisions."

E1609 is a Phase 3 study that enrolled 1,673 adult patients between May 2011 and August 2014 at multiple clinical sites, all belonging to the research groups in the NCI’s National Clinical Trials Network that design and lead trials focused on adult cancers: the Alliance for Clinical Trials in Oncology, ECOG-ACRIN Cancer Research Group, NRG Oncology, and SWOG. The study is comparing the effect of adjuvant Yervoy at either 3 mg/kg or 10 mg/kg versus high-dose interferon in adult patients with high-risk stage III or IV melanoma that has been removed by surgery. The study was not designed to compare the two Yervoy arms to each other. This analysis was performed to inform the effect of dose on efficacy and safety in the adjuvant setting. Co-primary endpoints of the study are overall survival and RFS comparing Yervoy versus high dose interferon α-2b. Secondary outcome measures include global quality of life and the safety profile of adjuvant Yervoy (10 mg/kg and 3 mg/kg) versus high-dose recombinant interferon α-2b. In this descriptive analysis, data was presented on the efficacy and safety of Yervoy 3 mg/kg and Yervoy 10 mg/kg at a median follow up of 3.1 years.

Adjuvant Therapy in Melanoma

Melanoma is separated into five staging categories (stages 0-4) based on the in-situ feature, thickness and ulceration of the tumor, whether the cancer has spread to the lymph nodes, and how far the cancer has spread beyond lymph nodes.

Stage 3 melanoma has reached the regional lymph nodes but has not yet spread to distant lymph nodes or to other parts of the body (metastasized), and requires surgical resection of the primary tumor as well as the involved lymph nodes. Some patients may also be treated with adjuvant therapy, although adjuvant treatment options are very limited. Despite surgical intervention and possible adjuvant treatment, most patients experience disease recurrence and progress to metastatic disease. By five years, the majority of stage 3B and 3C patients (68% and 89%, respectively) and a third of stage 3A patients (37%) have experienced disease recurrence.

At Bristol-Myers Squibb, patients are at the center of everything we do. Our vision for the future of cancer care is focused on researching and developing transformational Immuno-Oncology (I-O) medicines for hard-to-treat cancers that could potentially improve outcomes for these patients.

We are leading the scientific understanding of I-O through our extensive portfolio of investigational compounds and approved agents. Our differentiated clinical development program is studying broad patient populations across more than 50 types of cancers with 14 clinical-stage molecules designed to target different immune system pathways. Our deep expertise and innovative clinical trial designs position us to advance the I-O/I-O, I-O/chemotherapy, I-O/targeted therapies and I-O radiation therapies across multiple tumors and potentially deliver the next wave of therapies with a sense of urgency. We also continue to pioneer research that will help facilitate a deeper understanding of the role of immune biomarkers and how a patient’s tumor biology can be used as a guide for treatment decisions throughout their journey.

We understand making the promise of I-O a reality for the many patients who may benefit from these therapies requires not only innovation on our part but also close collaboration with leading experts in the field. Our partnerships with academia, government, advocacy and biotech companies support our collective goal of providing new treatment options to advance the standards of clinical practice.

About Yervoy

Yervoy is a recombinant, human monoclonal antibody that binds to the cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4). CTLA-4 is a negative regulator of T-cell activity. Yervoy binds to CTLA-4 and blocks the interaction of CTLA-4 with its ligands, CD80/CD86. Blockade of CTLA-4 has been shown to augment T-cell activation and proliferation, including the activation and proliferation of tumor infiltrating T-effector cells. Inhibition of CTLA-4 signaling can also reduce T-regulatory cell function, which may contribute to a general increase in T-cell responsiveness, including the anti-tumor immune response. On March 25, 2011, the U.S. Food and Drug Administration (FDA) approved Yervoy 3 mg/kg monotherapy for patients with unresectable or metastatic melanoma. Yervoy is approved for unresectable or metastatic melanoma in more than 50 countries. There is a broad, ongoing development program in place for Yervoy spanning multiple tumor types.

Indications and Important Safety Information for YERVOY (ipilimumab)

Indications

YERVOY (ipilimumab) is indicated for the treatment of unresectable or metastatic melanoma.

YERVOY (ipilimumab) is indicated for the adjuvant treatment of patients with cutaneous melanoma with pathologic involvement of regional lymph nodes of more than 1 mm who have undergone complete resection, including total lymphadenectomy.

Important Safety Information

WARNING: IMMUNE-MEDIATED ADVERSE REACTIONS

YERVOY (ipilimumab) can result in severe and fatal immune-mediated adverse reactions. These immune-mediated reactions may involve any organ system; however, the most common severe immune-mediated adverse reactions are enterocolitis, hepatitis, dermatitis (including toxic epidermal necrolysis), neuropathy, and endocrinopathy. The majority of these immune-mediated reactions initially manifested during treatment; however, a minority occurred weeks to months after discontinuation of YERVOY.

Permanently discontinue YERVOY and initiate systemic high-dose corticosteroid therapy for severe immune-mediated reactions.

Assess patients for signs and symptoms of enterocolitis, dermatitis, neuropathy, and endocrinopathy and evaluate clinical chemistries including liver function tests (LFTs), adrenocorticotropic hormone (ACTH) level, and thyroid function tests, at baseline and before each dose.

Recommended Dose Modifications

Endocrine: Withhold YERVOY for systemic endocrinopathy. Resume YERVOY in patients with complete or partial resolution of adverse reactions (Grade 0-1) and who are receiving <7.5 mg prednisone or equivalent per day. Permanently discontinue YERVOY for symptomatic reactions lasting 6 weeks or longer or an inability to reduce corticosteroid dose to 7.5 mg prednisone or equivalent per day.

Ophthalmologic: Permanently discontinue YERVOY for Grade 2-4 reactions not improving to Grade 1 within 2 weeks while receiving topical therapy or requiring systemic treatment.

All Other Organ Systems: Withhold YERVOY for Grade 2 adverse reactions. Resume YERVOY in patients with complete or partial resolution of adverse reactions (Grade 0-1) and who are receiving <7.5 mg prednisone or equivalent per day. Permanently discontinue YERVOY for Grade 2 reactions lasting 6 weeks or longer, an inability to reduce corticosteroid dose to 7.5 mg prednisone or equivalent per day, and Grade 3 or 4 adverse reactions.

Immune-mediated Enterocolitis:

Immune-mediated enterocolitis, including fatal cases, can occur with YERVOY. Monitor patients for signs and symptoms of enterocolitis (such as diarrhea, abdominal pain, mucus or blood in stool, with or without fever) and of bowel perforation (such as peritoneal signs and ileus). In symptomatic patients, rule out infectious etiologies and consider endoscopic evaluation for persistent or severe symptoms. Withhold YERVOY for moderate enterocolitis; administer anti-diarrheal treatment and, if persistent for >1 week, initiate systemic corticosteroids (0.5 mg/kg/day prednisone or equivalent). Permanently discontinue YERVOY in patients with severe enterocolitis and initiate systemic corticosteroids (1-2 mg/kg/day of prednisone or equivalent). Upon improvement to ≤Grade 1, initiate corticosteroid taper and continue over at least 1 month. In clinical trials, rapid corticosteroid tapering resulted in recurrence or worsening symptoms of enterocolitis in some patients. Consider adding anti-TNF or other immunosuppressant agents for management of immune-mediated enterocolitis unresponsive to systemic corticosteroids within 3-5 days or recurring after symptom improvement. In patients receiving YERVOY 3 mg/kg in Trial 1, severe, life-threatening, or fatal (diarrhea of ≥7 stools above baseline, fever, ileus, peritoneal signs; Grade 3-5) immune-mediated enterocolitis occurred in 34 YERVOY-treated patients (7%) and moderate (diarrhea with up to 6 stools above baseline, abdominal pain, mucus or blood in stool; Grade 2) enterocolitis occurred in 28 YERVOY-treated patients (5%). Across all YERVOY-treated patients (n=511), 5 (1%) developed intestinal perforation, 4 (0.8%) died as a result of complications, and 26 (5%) were hospitalized for severe enterocolitis. Infliximab was administered to 5 (8%) of the 62 patients with moderate, severe, or life-threatening immune-mediated enterocolitis following inadequate response to corticosteroids. In patients receiving YERVOY 10 mg/kg in Trial 2, Grade 3-5 immune-mediated enterocolitis occurred in 76 patients (16%) and Grade 2 enterocolitis occurred in 68 patients (14%). Seven (1.5%) developed intestinal perforation and 3 patients (0.6%) died as a result of complications.

Immune-mediated Hepatitis:

Immune-mediated hepatitis, including fatal cases, can occur with YERVOY. Monitor LFTs (hepatic transaminase and bilirubin levels) and assess patients for signs and symptoms of hepatotoxicity before each dose of YERVOY. In patients with hepatotoxicity, rule out infectious or malignant causes and increase frequency of LFT monitoring until resolution. Withhold YERVOY in patients with Grade 2 hepatotoxicity. Permanently discontinue YERVOY in patients with Grade 3-4 hepatotoxicity and administer systemic corticosteroids (1-2 mg/kg/day of prednisone or equivalent). When LFTs show sustained improvement or return to baseline, initiate corticosteroid tapering and continue over 1 month. Across the clinical development program for YERVOY, mycophenolate treatment has been administered in patients with persistent severe hepatitis despite high-dose corticosteroids. In patients receiving YERVOY 3 mg/kg in Trial 1, severe, life-threatening, or fatal hepatotoxicity (AST or ALT elevations >5× the ULN or total bilirubin elevations >3× the ULN; Grade 3-5) occurred in 8 YERVOY-treated patients (2%), with fatal hepatic failure in 0.2% and hospitalization in 0.4%. An additional 13 patients (2.5%) experienced moderate hepatotoxicity manifested by LFT abnormalities (AST or ALT elevations >2.5× but ≤5× the ULN or total bilirubin elevation >1.5× but ≤3× the ULN; Grade 2). In a dose-finding trial, Grade 3 increases in transaminases with or without concomitant increases in total bilirubin occurred in 6 of 10 patients who received concurrent YERVOY (3 mg/kg) and vemurafenib (960 mg BID or 720 mg BID). In patients receiving YERVOY 10 mg/kg in Trial 2, Grade 3-4 immune-mediated hepatitis occurred in 51 patients (11%) and moderate Grade 2 immune-mediated hepatitis occurred in 22 patients (5%). Liver biopsy performed in 6 patients with Grade 3-4 hepatitis showed evidence of toxic or autoimmune hepatitis.

Immune-mediated Dermatitis:

Immune-mediated dermatitis, including fatal cases, can occur with YERVOY. Monitor patients for signs and symptoms of dermatitis such as rash and pruritus. Unless an alternate etiology has been identified, signs or symptoms of dermatitis should be considered immune-mediated. Treat mild to moderate dermatitis (e.g., localized rash and pruritus) symptomatically; administer topical or systemic corticosteroids if there is no improvement within 1 week. Withhold YERVOY in patients with moderate to severe signs and symptoms. Permanently discontinue YERVOY in patients with severe, life-threatening, or fatal immune-mediated dermatitis (Grade 3-5). Administer systemic corticosteroids (1-2 mg/kg/day of prednisone or equivalent). When dermatitis is controlled, corticosteroid tapering should occur over a period of at least 1 month. In patients receiving YERVOY 3 mg/kg in Trial 1, severe, life-threatening, or fatal immune-mediated dermatitis (e.g., Stevens-Johnson syndrome, toxic epidermal necrolysis, or rash complicated by full thickness dermal ulceration, or necrotic, bullous, or hemorrhagic manifestations; Grade 3-5) occurred in 13 YERVOY-treated patients (2.5%); 1 patient (0.2%) died as a result of toxic epidermal necrolysis and 1 additional patient required hospitalization for severe dermatitis. There were 63 patients (12%) with moderate (Grade 2) dermatitis. In patients receiving YERVOY 10 mg/kg in Trial 2, Grade 3-4 immune-mediated dermatitis occurred in 19 patients (4%). There were 99 patients (21%) with moderate Grade 2 dermatitis.

Immune-mediated Neuropathies:

Immune-mediated neuropathies, including fatal cases, can occur with YERVOY. Monitor for symptoms of motor or sensory neuropathy such as unilateral or bilateral weakness, sensory alterations, or paresthesia. Withhold YERVOY in patients with moderate neuropathy (not interfering with daily activities). Permanently discontinue YERVOY in patients with severe neuropathy (interfering with daily activities), such as Guillain-Barre-like syndromes. Institute medical intervention as appropriate for management for severe neuropathy. Consider initiation of systemic corticosteroids (1-2 mg/kg/day of prednisone or equivalent) for severe neuropathies. In patients receiving YERVOY 3 mg/kg in Trial 1, 1 case of fatal Guillain-Barré syndrome and 1 case of severe (Grade 3) peripheral motor neuropathy were reported. Across the clinical development program of YERVOY, myasthenia gravis and additional cases of Guillain-Barré syndrome have been reported. In patients receiving YERVOY 10 mg/kg in Trial 2, Grade 3-5 immune-mediated neuropathy occurred in 8 patients (2%); the sole fatality was due to complications of Guillain-Barré syndrome. Moderate Grade 2 immune-mediated neuropathy occurred in 1 patient (0.2%).

Immune-mediated Endocrinopathies:

Immune-mediated endocrinopathies, including life-threatening cases, can occur with YERVOY. Monitor patients for clinical signs and symptoms of hypophysitis, adrenal insufficiency (including adrenal crisis), and hyper- or hypothyroidism. Patients may present with fatigue, headache, mental status changes, abdominal pain, unusual bowel habits, and hypotension, or nonspecific symptoms which may resemble other causes such as brain metastasis or underlying disease. Unless an alternate etiology has been identified, signs or symptoms should be considered immune-mediated. Monitor clinical chemistries, adrenocorticotropic hormone (ACTH) level, and thyroid function tests at the start of treatment, before each dose, and as clinically indicated based on symptoms. In a limited number of patients, hypophysitis was diagnosed by imaging studies through enlargement of the pituitary gland. Withhold YERVOY in symptomatic patients and consider referral to an endocrinologist. Initiate systemic corticosteroids (1-2 mg/kg/day of prednisone or equivalent) and initiate appropriate hormone replacement therapy. In patients receiving YERVOY 3 mg/kg in Trial 1, severe to life-threatening immune-mediated endocrinopathies (requiring hospitalization, urgent medical intervention, or interfering with activities of daily living; Grade 3-4) occurred in 9 YERVOY-treated patients (1.8%). All 9 patients had hypopituitarism, and some had additional concomitant endocrinopathies such as adrenal insufficiency, hypogonadism, and hypothyroidism. Six of the 9 patients were hospitalized for severe endocrinopathies. Moderate endocrinopathy (requiring hormone replacement or medical intervention; Grade 2) occurred in 12 patients (2.3%) and consisted of hypothyroidism, adrenal insufficiency, hypopituitarism, and 1 case each of hyperthyroidism and Cushing’s syndrome. The median time to onset of moderate to severe immune-mediated endocrinopathy was 2.5 months and ranged up to 4.4 months after the initiation of YERVOY. In patients receiving YERVOY 10 mg/kg in Trial 2, Grade 3-4 immune-mediated endocrinopathies occurred in 39 patients (8%) and Grade 2 immune-mediated endocrinopathies occurred in 93 patients (20%). Of the 39 patients with Grade 3-4 immune-mediated endocrinopathies, 35 patients had hypopituitarism (associated with 1 or more secondary endocrinopathies, e.g., adrenal insufficiency, hypogonadism, and hypothyroidism), 3 patients had hyperthyroidism, and 1 had primary hypothyroidism. The median time to onset of Grade 3-4 immune-mediated endocrinopathy was 2.2 months (range: 2 days-8 months). Twenty-seven (69.2%) of the 39 patients were hospitalized for immune-mediated endocrinopathies. Of the 93 patients with Grade 2 immune-mediated endocrinopathy, 74 had primary hypopituitarism (associated with 1 or more secondary endocrinopathy, e.g., adrenal insufficiency, hypogonadism, and hypothyroidism), 9 had primary hypothyroidism, 3 had hyperthyroidism, 3 had thyroiditis with hypo- or hyperthyroidism, 2 had hypogonadism, 1 had both hyperthyroidism and hypopituitarism, and 1 subject developed Graves’ ophthalmopathy. The median time to onset of Grade 2 immune-mediated endocrinopathy was 2.1 months (range: 9 days-19.3 months).

Other Immune-mediated Adverse Reactions, Including Ocular Manifestations:

Permanently discontinue YERVOY for clinically significant or severe immune-mediated adverse reactions. Initiate systemic corticosteroids (1-2 mg/kg/day of prednisone or equivalent) for severe immune-mediated adverse reactions. Administer corticosteroid eye drops for uveitis, iritis, or episcleritis. Permanently discontinue YERVOY for immune-mediated ocular disease unresponsive to local immunosuppressive therapy. In Trial 1, the following clinically significant immune-mediated adverse reactions were seen in <1% of YERVOY-treated patients: nephritis, pneumonitis, meningitis, pericarditis, uveitis, iritis, and hemolytic anemia. In Trial 2, the following clinically significant immune-mediated adverse reactions were seen in <1% of YERVOY-treated patients unless specified: eosinophilia (2.1%), pancreatitis (1.3%), meningitis, pneumonitis, sarcoidosis, pericarditis, uveitis and fatal myocarditis. Across 21 dose-ranging trials administering YERVOY at doses of 0.1 to 20 mg/kg (n=2478), the following likely immune-mediated adverse reactions were also reported with <1% incidence: angiopathy, temporal arteritis, vasculitis, polymyalgia rheumatica, conjunctivitis, blepharitis, episcleritis, scleritis, iritis, leukocytoclastic vasculitis, erythema multiforme, psoriasis, arthritis, autoimmune thyroiditis, neurosensory hypoacusis, autoimmune central neuropathy (encephalitis), myositis, polymyositis, ocular myositis, hemolytic anemia, and nephritis.

Embyro-fetal Toxicity

Based on its mechanism of action, YERVOY can cause fetal harm when administered to a pregnant woman. The effects of YERVOY are likely to be greater during the second and third trimesters of pregnancy. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with a YERVOY-containing regimen and for 3 months after the last dose of YERVOY.

Lactation

It is not known whether YERVOY is secreted in human milk. Advise women to discontinue nursing during treatment with YERVOY and for 3 months following the final dose.

Common Adverse Reactions:

The most common adverse reactions (≥5%) in patients who received YERVOY at 3 mg/kg were fatigue (41%), diarrhea (32%), pruritis (31%), rash (29%), and colitis (8%). The most common adverse reactions (≥5%) in patients who received YERVOY at 10 mg/kg were rash (50%), diarrhea (49%), fatigue (46%), pruritus (45%), headache (33%), weight loss (32%), nausea (25%), pyrexia (18%), colitis (16%), decreased appetite (14%), vomiting (13%), and insomnia (10%).

Yervoy is a registered trademark of Bristol-Myers Squibb Company.

On June 4, 2017 Bristol-Myers Squibb Company (NYSE:BMY) reported efficacy and safety data from CheckMate -204, the first Phase 2 study to evaluate Opdivo plus Yervoy as a potential treatment for patients with melanoma metastatic to the brain (Press release, Bristol-Myers Squibb, JUN 4, 2017, View Source [SID1234519362]). The primary endpoint of intracranial (IC) clinical benefit rate (CBR), defined as complete response plus partial response plus stable disease ≥ 6 months, was 60% (95% CI: 48 to 71) at the median follow-up of 9.2 months among the 75 evaluated patients. These data will be presented during an oral session today from 10:12 – 10:24 a.m. CDT during the Melanoma/Skin Cancers session in the Arie Crown Theater at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting 2017.

"More than 60 percent of patients with stage IV melanoma eventually develop brain metastases, which are a major cause of illness and death among these patients," said Hussein Tawbi, M.D., PhD, Associate Professor, Department of Melanoma Medical Oncology, The University of Texas MD Anderson Cancer Center. "These results from the CheckMate -204 trial are the first efficacy data investigating the use of an Immuno-Oncology combination for the treatment of patients with untreated melanoma brain metastases. The use of upfront systemic therapy is a novel approach in this population where radiation therapy is the norm."

A complete IC response was achieved by 21% (n=16) of patients; 33% (n=25) had partial responses; and 5% (n=4) experienced stable disease. The IC objective response rate (ORR) was 55% (95% CI: 43 to 66) with a safety profile consistent with previously reported data in melanoma patients without brain metastases. Treatment-related grade 3/4 adverse events (AEs) occurred in 52% of patients (n=39), with 8% (n=6) being neurologic in nature, including headaches. Three treatment-related deaths were reported as cardiogenic shock, IC hemorrhage and malignant neoplasm progression.

"The CheckMate -204 trial is important because research about therapies for advanced melanoma patients with brain metastases is somewhat limited. Until recently, these patients have been excluded from clinical trials," said Vicki Goodman, M.D., development lead, Melanoma and Genitourinary Cancers, Bristol-Myers Squibb. "These data add to the body of scientific knowledge on Opdivo and Yervoy and highlight our continued commitment to researching the potential benefits of this combination in a diverse set of patient groups."

CheckMate -204 is a Phase 2 open-label study in 75 patients with melanoma that had spread to the brain, resulting in one or more asymptomatic brain metastases of 0.5 to 3.0 cm. The trial evaluated the efficacy and safety of Opdivo in combination with Yervoy followed by Opdivo monotherapy. The primary endpoint was IC CBR. Secondary objectives included overall survival, extracranial CBR and safety.

Enrolled patients received Opdivo 1 mg/kg plus Yervoy 3 mg/kg every three weeks for four doses, followed by Opdivo 3 mg/kg every two weeks until disease progression or toxicity. Patients who experienced severe AEs during the combination treatment could receive Opdivo monotherapy when their toxicity resolved, and stereotactic radiotherapy was permitted for patients experiencing brain oligo-progression if an assessable brain metastasis remained. The median number of combination doses was three (range 1 to 4), and 28 patients (37%) received four combination induction doses and 42 patients (56%) began Opdivo maintenance (median 12 doses, range 1 to 36).

About Metastatic Melanoma

Melanoma is a form of skin cancer characterized by the uncontrolled growth of pigment-producing cells (melanocytes) located in the skin. Metastatic melanoma is the deadliest form of the disease and occurs when cancer spreads beyond the surface of the skin to other organs. The incidence of melanoma has been increasing steadily for the last 30 years. In the United States, 87,000 new diagnoses of melanoma and more than 9,700 related deaths are estimated for 2017. Globally, the World Health Organization estimates that by 2035, melanoma incidence will reach 388,262, with 98,288 related deaths. Melanoma is mostly curable when treated in its early stages. However, patients in the United States diagnosed with advanced melanoma classified as Stage IV historically have a five-year survival rate of 15% to 20% and 10-year survival of about 10% to 15%.

We understand making the promise of I-O a reality for the many patients who may benefit from these therapies requires not only innovation on our part but also close collaboration with leading experts in the field. Our partnerships with academia, government, advocacy and biotech companies support our collective goal of providing new treatment options to advance the standards of clinical practice.

About Opdivo

Opdivo is a programmed death-1 (PD-1) immune checkpoint inhibitor that is designed to uniquely harness the body’s own immune system to help restore anti-tumor immune response. By harnessing the body’s own immune system to fight cancer, Opdivo has become an important treatment option across multiple cancers.

Opdivo’s leading global development program is based on Bristol-Myers Squibb’s scientific expertise in the field of Immuno-Oncology and includes a broad range of clinical trials across all phases, including Phase 3, in a variety of tumor types. To date, the Opdivo clinical development program has enrolled more than 25,000 patients. The Opdivo trials have contributed to gaining a deeper understanding of the potential role of biomarkers in patient care, particularly regarding how patients may benefit from Opdivo across the continuum of PD-L1 expression.

In July 2014, Opdivo was the first PD-1 immune checkpoint inhibitor to receive regulatory approval anywhere in the world. Opdivo is currently approved in more than 60 countries, including the United States, the European Union and Japan. In October 2015, the company’s Opdivo and Yervoy combination regimen was the first Immuno-Oncology combination to receive regulatory approval for the treatment of metastatic melanoma and is currently approved in more than 50 countries, including the United States and the European Union.

IMPORTANT SAFETY INFORMATION

WARNING: IMMUNE-MEDIATED ADVERSE REACTIONS

YERVOY can result in severe and fatal immune-mediated adverse reactions. These immune-mediated reactions may involve any organ system; however, the most common severe immune-mediated adverse reactions are enterocolitis, hepatitis, dermatitis (including toxic epidermal necrolysis), neuropathy, and endocrinopathy. The majority of these immune-mediated reactions initially manifested during treatment; however, a minority occurred weeks to months after discontinuation of YERVOY.

Assess patients for signs and symptoms of enterocolitis, dermatitis, neuropathy, and endocrinopathy and evaluate clinical chemistries including liver function tests (LFTs), adrenocorticotropic hormone (ACTH) level, and thyroid function tests at baseline and before each dose.

Permanently discontinue YERVOY and initiate systemic high-dose corticosteroid therapy for severe immune-mediated reactions.

Immune-Mediated Pneumonitis

OPDIVO can cause immune-mediated pneumonitis. Fatal cases have been reported. Monitor patients for signs with radiographic imaging and for symptoms of pneumonitis. Administer corticosteroids for Grade 2 or more severe pneumonitis. Permanently discontinue for Grade 3 or 4 and withhold until resolution for Grade 2. In patients receiving OPDIVO monotherapy, fatal cases of immune-mediated pneumonitis have occurred. Immune-mediated pneumonitis occurred in 3.1% (61/1994) of patients. In patients receiving OPDIVO with YERVOY, immune-mediated pneumonitis occurred in 6% (25/407) of patients.

In Checkmate 205 and 039, pneumonitis, including interstitial lung disease, occurred in 6.0% (16/266) of patients receiving OPDIVO. Immune-mediated pneumonitis occurred in 4.9% (13/266) of patients receiving OPDIVO: Grade 3 (n=1) and Grade 2 (n=12).

Immune-Mediated Encephalitis

OPDIVO can cause immune-mediated encephalitis. Evaluation of patients with neurologic symptoms may include, but not be limited to, consultation with a neurologist, brain MRI, and lumbar puncture. Withhold OPDIVO in patients with new-onset moderate to severe neurologic signs or symptoms and evaluate to rule out other causes. If other etiologies are ruled out, administer corticosteroids and permanently discontinue OPDIVO for immune-mediated encephalitis. In patients receiving OPDIVO monotherapy, encephalitis occurred in 0.2% (3/1994) of patients. Fatal limbic encephalitis occurred in one patient after 7.2 months of exposure despite discontinuation of OPDIVO and administration of corticosteroids. Encephalitis occurred in one patient receiving OPDIVO with YERVOY (0.2%) after 1.7 months of exposure.

Other Immune-Mediated Adverse Reactions

Based on the severity of adverse reaction, permanently discontinue or withhold treatment, administer high-dose corticosteroids, and, if appropriate, initiate hormone-replacement therapy. Across clinical trials of OPDIVO the following clinically significant immune-mediated adverse reactions occurred in <1.0% of patients receiving OPDIVO: uveitis, iritis, pancreatitis, facial and abducens nerve paresis, demyelination, polymyalgia rheumatica, autoimmune neuropathy, Guillain-Barré syndrome, hypopituitarism, systemic inflammatory response syndrome, gastritis, duodenitis, sarcoidosis, histiocytic necrotizing lymphadenitis (Kikuchi lymphadenitis), myositis, myocarditis, rhabdomyolysis, motor dysfunction, vasculitis, and myasthenic syndrome.

Infusion Reactions

OPDIVO can cause severe infusion reactions, which have been reported in <1.0% of patients in clinical trials. Discontinue OPDIVO in patients with Grade 3 or 4 infusion reactions. Interrupt or slow the rate of infusion in patients with Grade 1 or 2. In patients receiving OPDIVO monotherapy, infusion-related reactions occurred in 6.4% (127/1994) of patients. In patients receiving OPDIVO with YERVOY, infusion-related reactions occurred in 2.5% (10/407) of patients.

Complications of Allogeneic HSCT after OPDIVO

Complications, including fatal events, occurred in patients who received allogeneic HSCT after OPDIVO. Outcomes were evaluated in 17 patients from Checkmate 205 and 039, who underwent allogeneic HSCT after discontinuing OPDIVO (15 with reduced-intensity conditioning, 2 with myeloablative conditioning). Thirty-five percent (6/17) of patients died from complications of allogeneic HSCT after OPDIVO. Five deaths occurred in the setting of severe or refractory GVHD. Grade 3 or higher acute GVHD was reported in 29% (5/17) of patients. Hyperacute GVHD was reported in 20% (n=2) of patients. A steroid-requiring febrile syndrome, without an identified infectious cause, was reported in 35% (n=6) of patients. Two cases of encephalitis were reported: Grade 3 (n=1) lymphocytic encephalitis without an identified infectious cause, and Grade 3 (n=1) suspected viral encephalitis. Hepatic veno-occlusive disease (VOD) occurred in one patient, who received reduced-intensity conditioned allogeneic HSCT and died of GVHD and multi-organ failure. Other cases of hepatic VOD after reduced-intensity conditioned allogeneic HSCT have also been reported in patients with lymphoma who received a PD-1 receptor blocking antibody before transplantation. Cases of fatal hyperacute GVHD have also been reported. These complications may occur despite intervening therapy between PD-1 blockade and allogeneic HSCT.

Follow patients closely for early evidence of transplant-related complications such as hyperacute GVHD, severe (Grade 3 to 4) acute GVHD, steroid-requiring febrile syndrome, hepatic VOD, and other immune-mediated adverse reactions, and intervene promptly.

Embryo-Fetal Toxicity

Based on their mechanisms of action, OPDIVO and YERVOY can cause fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with an OPDIVO- or YERVOY- containing regimen and for at least 5 months after the last dose of OPDIVO.

Lactation

It is not known whether OPDIVO or YERVOY is present in human milk. Because many drugs, including antibodies, are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from an OPDIVO-containing regimen, advise women to discontinue breastfeeding during treatment. Advise women to discontinue nursing during treatment with YERVOY and for 3 months following the final dose.

On June 4, 2017 AstraZeneca reported positive results from its Phase III OlympiAD trial that showed a statistically-significant and clinically-meaningful improvement in progression-free survival (PFS) for patients treated with Lynparza (olaparib) tablets (300mg twice daily), compared to treatment with physician’s choice of a standard of care chemotherapy (Press release, AstraZeneca, JUN 4, 2017, View Source [SID1234519360]). In addition to meeting its primary endpoint of PFS assessed by blinded independent central review (BICR), the trial showed that patients treated with Lynparza had a 42% reduction in risk of their disease worsening or death (HR 0.58; 95% CI 0.43-0.80; p=0.0009; median 7.0 vs 4.2 months) compared to those who received chemotherapy (capecitabine, vinorelbine, eribulin).

The data were presented at the 2017 ASCO (Free ASCO Whitepaper) Annual Meeting in Chicago, during today’s Plenary Session from 15:10-15:25 CDT (Abstract LBA4).[i] The trial was designated for the "Best of ASCO (Free ASCO Whitepaper)" selection, underscoring the importance of these results for patients and physicians, and the results have been published in the New England Journal of Medicine today.

Mark E. Robson, Clinic Director of the Clinical Genetics Service at Memorial Sloan Kettering Cancer Center, New York and Principal Investigator of OlympiAD said, "The OlympiAD data presented today demonstrate the benefit of olaparib in delaying the progression of advanced BRCA-mutated breast cancer. With few alternatives available, a targeted non-chemotherapy oral treatment in this setting could be a beneficial new option for patients."

Sean Bohen, Executive Vice President, Global Medicines Development and Chief Medical Officer at AstraZeneca, said, "The OlympiAD results shared today mark the first time a targeted therapy shows benefit over the current standard of care for patients with HER2-negative gBRCA-mutated metastatic breast cancer. This also represents an important milestone for Lynparza as this is the first positive Phase III trial in which a PARP inhibitor has shown a significant benefit for patients outside of ovarian cancer."

Patients in the trial had HER2-negative germline BRCA1 or BRCA2-mutated breast cancer and were receiving Lynparza as their first, second or third-line medicine for metastatic disease. Before enrolment, patients had prior treatment with an anthracycline (unless contraindicated) and a taxane; hormone receptor-positive patients received at least one endocrine medicine or were not eligible for endocrine medicines.i

Secondary endpoints showed an improvement in time until second progression or death (PFS2) in the Lynparza arm of the trial, compared to those treated with chemotherapy (HR 0.57; 95% CI: 0.40-0.83).i In addition, the objective response rate (ORR) was more than doubled, with 59.9% of patients in the Lynparza arm showing response to treatment, compared to 28.8% of patients treated with chemotherapy.i

A review of the Lynparza safety data from the OlympiAD trial did not identify any new safety signals and the overall safety profile was consistent with previous trials of Lynparza. There was a lower incidence of grade ≥3 adverse events in the Lynparza arm compared to the chemotherapy arm (36.6% vs 50.5% respectively). A smaller proportion of patients discontinued treatment in the Lynparza arm compared to the chemotherapy arm (4.9% vs 7.7% respectively).



NOTES TO EDITORS
About OlympiAD

OlympiAD is a randomised, open label, multi-centre Phase III trial assessing the efficacy and safety of Lynparza (300mg tablets twice daily) to ‘physician’s choice’ chemotherapy (capecitabine, vinorelbine, eribulin) in 302 patients with HER2-negative metastatic breast cancer with germline BRCA1 or BRCA2 mutations, which are predicted or suspected to be deleterious. The international trial was conducted in 19 countries from across Europe, Asia, North America and South America.

Within the eligible patient population, there was a 1:1 ratio between triple-negative breast cancer (TNBC) and hormone receptor positive (ER+ and/or PR+) patients.

The primary endpoint of the trial was progression-free survival (PFS) as measured by a Blinded Independent Central Review (BICR). Secondary endpoints include overall survival (OS), time to second progression or death (PFS2), objective response rate (ORR), and effect on health-related quality of life (HRQoL).i

About Lynparza (olaparib)

Lynparza (olaparib) is an innovative, first-in-class oral poly ADP-ribose polymerase (PARP) inhibitor that may exploit tumour DNA damage response (DDR) pathway deficiencies to preferentially kill cancer cells. Lynparza is the foundation of AstraZeneca’s industry-leading portfolio of approved and potential new medicines targeting DNA damage response (DDR) mechanisms in cancer cells.

Lynparza is currently approved by regulatory health authorities in the EU for use as monotherapy for the maintenance treatment of adult patients with platinum-sensitive relapsed BRCA-mutated (germline and/or somatic) high grade serous epithelial ovarian, fallopian tube or primary peritoneal cancer who are in response (complete or partial) to platinum-based chemotherapy.[ii] It is also approved in the US as monotherapy in patients with deleterious or suspected deleterious germline BRCA-mutated (as detected by an FDA-test) advanced ovarian cancer who have been treated with three or more prior lines of chemotherapy.[iii]

Lynparza is currently being tested in another separate adjuvant (non-metastatic) breast cancer Phase III trial called OLYMPIA. This trial is still open and recruiting patients internationally.

About Metastatic Breast Cancer

Approximately one in eight women will be diagnosed with breast cancer in the US.[iv] Of these patients, approximately one third are either diagnosed with, or progress to, the metastatic stage of the disease.[v] Despite treatment options increasing during the past three decades there is currently no cure for patients diagnosed with metastatic breast cancer. Thus, the primary aim of treatment is to slow progression of the disease for as long as possible, improving, or at least maintaining, a patient’s quality of life.

About Germline BRCA mutations

BRCA1 and BRCA2 are human genes that produce proteins responsible for repairing damaged DNA and play an important role in maintaining the genetic stability of cells. When either of these genes is mutated, or altered, such that its protein is either not made or is faulty, DNA damage may not be repaired properly. As a result, cells are more likely to develop additional genetic alterations that can lead to cancer.[vi]

Specific inherited mutations in BRCA1 and BRCA2 increase the risk of female breast and ovarian cancers, among others. Together, BRCA1 and BRCA2 mutations account for about 20 to 25% of hereditary breast cancers[vii] and about 5 to 10% of all breast cancers[viii]. In addition, mutations in BRCA1 and BRCA2 account for around 15% of ovarian cancers overall Breast and ovarian cancers associated with BRCA1 and BRCA2 mutations tend to develop at younger ages than their nonhereditary counterparts.

About AstraZeneca in Oncology

AstraZeneca has a deep-rooted heritage in Oncology and offers a quickly growing portfolio of new medicines that have the potential to transform patients’ lives and the Company’s future.

The study met its primary endpoint, demonstrating XGEVA is non-inferior to zoledronic acid in delaying the time to first on-study skeletal-related event in patients with multiple myeloma (HR=0.98, 95 percent CI: 0.85, 1.14; p=0.01). The analysis demonstrated that patients on XGEVA had a significantly lower rate of renal adverse events compared to zoledronic acid (10.0 percent versus 17.1 percent, p<0.001). These results will be presented today during an oral session at the 53rd Annual Meeting of the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper). The analysis was also selected for the Best of ASCO (Free ASCO Whitepaper) educational program, which is designed to increase access to practice-changing advances in cancer treatment.

The results presented today showed that in patients with renal insufficiency, defined as having a creatinine clearance (CrCl) of less than or equal to 60 mL/min, the rate of renal adverse events was double in the zoledronic acid arm compared to the XGEVA arm (26.4 percent versus 12.9 percent, respectively). The zoledronic acid label does not recommend treatment in patients with a CrCl of less than 30 mL/min; therefore, patients with severe renal impairment were excluded from this study.1 Median cumulative exposure to XGEVA was 15.75 months compared to 14.78 months for zoledronic acid.

"Bone complications in multiple myeloma patients, including fractures, can have a devastating impact on patients. Current treatment options for these complications are limited to bisphosphonates, including zoledronic acid, which are cleared by the kidneys and can be associated with increased renal toxicity," said Noopur Raje, M.D., director, Center for Multiple Myeloma, Massachusetts General Hospital Cancer Center, Boston. "Renal impairment is a common complication in multiple myeloma patients. Denosumab, which is not cleared by the kidneys, may offer a novel, safe and effective option for multiple myeloma patients."

XGEVA is currently indicated for the prevention of fractures and other skeletal-related events in patients with bone metastases from solid tumors and is the number one prescribed agent for this indication in the United States (U.S.). XGEVA is currently not indicated for the prevention of skeletal-related events in patients with multiple myeloma. On April 4, 2017, Amgen announced the submission of a supplemental Biologics License Application to the U.S. Food and Drug Administration and an application for a variation to the marketing authorization to the European Medicines Agency for XGEVA. The submissions to regulatory authorities seek to expand the currently approved XGEVA indication to include patients with multiple myeloma.

"Preventing fractures and other bone complications and preserving renal function are two of the most important aspects to consider when caring for patients with multiple myeloma," said Sean E. Harper, M.D., executive vice president of Research and Development at Amgen. "Up to 40 percent of patients remain untreated for the prevention of bone complications, and the percentage is highest among patients with renal impairment at the time of diagnosis, underscoring the need for alternative treatment options. We look forward to making XGEVA, a novel treatment option, available to multiple myeloma patients."

Data from the ‘482 study were previously presented at the 16th International Myeloma Workshop (IMW), including additional endpoints. These results demonstrated that the hazard ratio of overall survival, a secondary endpoint of the study, was 0.90 for XGEVA as compared to zoledronic acid (95 percent CI: 0.70, 1.16). The hazard ratio of XGEVA versus zoledronic acid for progression-free survival, an exploratory endpoint, was 0.82 (95 percent CI: 0.68, 0.99; descriptive p=0.036). The median difference in progression-free survival between arms was 10.7 months in favor of XGEVA.

About the ‘482 Study (NCT01345019)
The ‘482 study was an international, Phase 3, randomized, double-blind, multicenter trial of XGEVA compared with zoledronic acid in the prevention of fractures and other skeletal-related events in adult patients with newly diagnosed multiple myeloma and bone disease. In the study, a total of 1,718 patients (859 on each arm) were randomized to receive either subcutaneous XGEVA 120 mg and intravenous placebo every four weeks, or intravenous zoledronic acid 4 mg (adjusted for renal function) and subcutaneous placebo every four weeks. The primary endpoint of the study was non-inferiority of XGEVA versus zoledronic acid with respect to time to first on-study skeletal-related event (pathologic fracture, radiation to bone, surgery to bone or spinal cord compression). Secondary endpoints included superiority of XGEVA versus zoledronic acid with respect to time to first on-study skeletal-related event and first-and-subsequent on-study skeletal-related event and evaluation of overall survival. Progression-free survival was an exploratory endpoint. The safety and tolerability of XGEVA were also compared with zoledronic acid. An increased risk of hypocalcemia has been observed in clinical trials of patients with increasing renal dysfunction, most commonly with severe dysfunction.

About Multiple Myeloma and Bone Complications
Multiple myeloma is the second most common hematologic cancer, and it develops in plasma cells located in the bone marrow microenvironment.2,3 It is typically characterized by osteolytic bone lesions as well as renal failure, which are both part of diagnosis (CRAB criteria).4,5 Each year an estimated 114,000 new cases of multiple myeloma are diagnosed worldwide, resulting in more than 80,000 deaths per year.2

More than 90 percent of patients develop osteolytic lesions during the course of the disease.4 Preventing bone complications is a critical aspect of caring for patients with multiple myeloma, because these events can cause significant morbidity.6 Current treatment options for fractures and other bone complications are limited to bisphosphonates, including zoledronic acid, which are cleared through the kidneys.7 Approximately 60 percent of all multiple myeloma patients have or will develop renal impairment over the course of the disease.8

About XGEVA (denosumab)
XGEVA targets the RANK ligand pathway to prevent the formation, function and survival of osteoclasts, which break down bone. As a monoclonal antibody, XGEVA is not cleared by the kidneys. XGEVA is indicated for the prevention of skeletal-related events in patients with bone metastases from solid tumors. Limitation of use: XGEVA is not indicated for the prevention of skeletal-related events in patients with multiple myeloma. XGEVA is also indicated for treatment of adults and skeletally mature adolescents with giant cell tumor of bone that is unresectable or where surgical resection is likely to result in severe morbidity. XGEVA is also indicated in the U.S. for the treatment of hypercalcemia of malignancy refractory to bisphosphonate therapy.

U.S. Important Safety Information

Hypocalcemia
Pre-existing hypocalcemia must be corrected prior to initiating therapy with XGEVA. XGEVA can cause severe symptomatic hypocalcemia, and fatal cases have been reported. Monitor calcium levels, especially in the first weeks of initiating therapy, and administer calcium, magnesium, and vitamin D as necessary. Monitor levels more frequently when XGEVA is administered with other drugs that can also lower calcium levels. Advise patients to contact a healthcare professional for symptoms of hypocalcemia.

An increased risk of hypocalcemia has been observed in clinical trials of patients with increasing renal dysfunction, most commonly with severe dysfunction (creatinine clearance less than 30 mL/minute and/or on dialysis), and with inadequate/no calcium supplementation. Monitor calcium levels and calcium and vitamin D intake.

Hypersensitivity
XGEVA is contraindicated in patients with known clinically significant hypersensitivity to XGEVA, including anaphylaxis that has been reported with use of XGEVA. Reactions may include hypotension, dyspnea, upper airway edema, lip swelling, rash, pruritus, and urticaria. If an anaphylactic or other clinically significant allergic reaction occurs, initiate appropriate therapy and discontinue XGEVA therapy permanently.

Drug Products with Same Active Ingredient
Patients receiving XGEVA should not take Prolia (denosumab).

Osteonecrosis of the Jaw
Osteonecrosis of the jaw (ONJ) has been reported in patients receiving XGEVA, manifesting as jaw pain, osteomyelitis, osteitis, bone erosion, tooth or periodontal infection, toothache, gingival ulceration, or gingival erosion. Persistent pain or slow healing of the mouth or jaw after dental surgery may also be manifestations of ONJ. In clinical trials in patients with osseous metastasis, the incidence of ONJ was higher with longer duration of exposure.

Patients with a history of tooth extraction, poor oral hygiene, or use of a dental appliance are at a greater risk to develop ONJ. Other risk factors for the development of ONJ include immunosuppressive therapy, treatment with angiogenesis inhibitors, systemic corticosteroids, diabetes, and gingival infections.

Perform an oral examination and appropriate preventive dentistry prior to the initiation of XGEVA and periodically during XGEVA therapy. Advise patients regarding oral hygiene practices. Avoid invasive dental procedures during treatment with XGEVA. Consider temporarily interrupting XGEVA therapy if an invasive dental procedure must be performed.

Patients who are suspected of having or who develop ONJ while on XGEVA should receive care by a dentist or an oral surgeon. In these patients, extensive dental surgery to treat ONJ may exacerbate the condition.

Atypical Subtrochanteric and Diaphyseal Femoral Fracture
Atypical femoral fracture has been reported with XGEVA. These fractures can occur anywhere in the femoral shaft from just below the lesser trochanter to above the supracondylar flare and are transverse or short oblique in orientation without evidence of comminution.

Atypical femoral fractures most commonly occur with minimal or no trauma to the affected area. They may be bilateral and many patients report prodromal pain in the affected area, usually presenting as dull, aching thigh pain, weeks to months before a complete fracture occurs. A number of reports note that patients were also receiving treatment with glucocorticoids (e.g. prednisone) at the time of fracture. During XGEVA treatment, patients should be advised to report new or unusual thigh, hip, or groin pain. Any patient who presents with thigh or groin pain should be suspected of having an atypical fracture and should be evaluated to rule out an incomplete femur fracture. Patients presenting with an atypical femur fracture should also be assessed for symptoms and signs of fracture in the contralateral limb. Interruption of XGEVA therapy should be considered, pending a risk/benefit assessment, on an individual basis.

Hypercalcemia Following Treatment Discontinuation in Patients with Growing Skeletons
Clinically significant hypercalcemia has been reported in XGEVA treated patients with growing skeletons, weeks to months following treatment discontinuation. Monitor patients for signs and symptoms of hypercalcemia and treat appropriately.

Embryo-Fetal Toxicity
XGEVA can cause fetal harm when administered to a pregnant woman. Based on findings in animals, XGEVA is expected to result in adverse reproductive effects.

Advise females of reproductive potential to use highly effective contraception during therapy, and for at least 5 months after the last dose of XGEVA. Apprise the patient of the potential hazard to a fetus if XGEVA is used during pregnancy or if the patient becomes pregnant while patients are exposed to XGEVA.

Adverse Reactions
The most common adverse reactions in patients receiving XGEVA with bone metastasis from solid tumors were fatigue/asthenia, hypophosphatemia, and nausea. The most common serious adverse reaction was dyspnea. The most common adverse reactions resulting in discontinuation were osteonecrosis and hypocalcemia.

The most common adverse reactions in patients receiving XGEVA for giant cell tumor of bone were arthralgia, headache, nausea, back pain, fatigue, and pain in extremity. The most common serious adverse reactions were osteonecrosis of the jaw and osteomyelitis. The most common adverse reactions resulting in discontinuation of XGEVA were osteonecrosis of the jaw and tooth abscess or tooth infection.

The most common adverse reactions in patients receiving XGEVA for hypercalcemia of malignancy were nausea, dyspnea, decreased appetite, headache, peripheral edema, vomiting, anemia, constipation, and diarrhea.

Denosumab is also marketed as Prolia in other indications.
