On July 11, 2018 Seattle Genetics, Inc. (Nasdaq:SGEN) reported that results of a phase 1b clinical trial of tucatinib in combination with standard of care agents for the treatment of patients with advanced HER2-positive (HER2+) metastatic breast cancer were recently published in the journal The Lancet Oncology (Press release, Seattle Genetics, JUL 11, 2018, View Source;p=RssLanding&cat=news&id=2357794 [SID1234527644]). Results demonstrated that tucatinib in combination with trastuzumab (Herceptin) and capecitabine (Xeloda) was generally well-tolerated and had encouraging clinical activity in heavily pre-treated patients with advanced HER2+ breast cancer, including those with brain metastases (ONT-380-005/triplet study). A separate phase 1b clinical trial of tucatinib in combination with ado-trastuzumab emtansine (T-DM1, Kadcyla) was published in JAMA Oncology. Results showed an acceptable safety profile and preliminary antitumor activity among heavily pretreated patients with HER2+ metastatic breast cancer, with and without brain metastases (ONT-380-004). Tucatinib is an oral, small molecule tyrosine kinase inhibitor that is highly selective for HER2.

"There remains a need for a well-tolerated, oral targeted therapy to treat patients with HER2+ metastatic breast cancer whose disease progresses on conventional anti-HER2 treatments, particularly for those whose cancer has metastasized to the brain, which occurs in up to 50 percent of these patients," said Rashmi Murthy, M.D., MBE, Assistant Professor, Department of Breast Medical Oncology, Division of Cancer Medicine, The University of Texas MD Anderson Cancer Center. "In the ONT-380-005 triplet study, durable responses were seen in heavily pretreated patients with metastatic HER2+ breast cancer, including those with brain metastases, after treatment with tucatinib. Importantly, in the trial, tucatinib treatment was associated with few clinically significant side effects, such as diarrhea or skin rash, commonly seen with other tyrosine kinase inhibitors targeting this disease, which may allow for prolonged use and as a result potentially improve outcomes for patients."

"The results of the combination tucatinib with trastuzumab and capecitabine triplet study support the development of this regimen in the ongoing pivotal HER2CLIMB trial to provide a meaningful advancement in the use of targeted therapies to treat this disease," said Roger Dansey, M.D., Chief Medical Officer at Seattle Genetics. "In addition, based on the results of the combination of tucatinib with T-DM1, we are evaluating development opportunities for this combination in earlier lines of HER2+ metastatic breast cancer."

The manuscript entitled "Tucatinib with capecitabine and trastuzumab in advanced HER2-positive metastatic breast cancer with and without brain metastases: a non-randomized, open-label, phase 1b study" was published in the July print edition of The Lancet Oncology.

The phase 1b triplet study was an open-label dose-escalation and expansion cohort study of tucatinib in combination with capecitabine and/or trastuzumab in patients with HER2+ metastatic breast cancer, including those with or without brain metastases. The objective of the study was to assess the safety, tolerability, pharmacokinetics and antitumor activity, and to determine the recommended phase 2 dose of tucatinib in combination with these agents. Once a recommended phase 2 dose of 300 mg BID was established in the triplet combination, an expansion cohort using that regimen was opened. The trial enrolled 60 patients with HER2+ metastatic breast cancer who had previously received a median of three HER2-targeted agents, such as trastuzumab, pertuzumab (Perjeta), lapatinib (Tykerb) or T-DM1.

Data from patients treated with the triplet combination at 300 mg BID (n=27) included:

Median progression-free survival (PFS) was 7.8 months.
Objective response rate (ORR) was 61 percent (n=14/23) with a median duration of response of 11.0 months.
Median PFS for patients with brain metastases (n=11) was 6.7 months.
ORR was 42 percent (n=5/12) in patients with measurable brain metastases that had received the 300mg BID tucatinib dose in any combination.
The triplet combination was well-tolerated and the majority of adverse events were grade 1, with most patients being able to continue on the full dose of tucatinib. Grade 3 diarrhea was infrequent without a requirement for prophylactic anti-diarrheal medicine.
An ongoing randomized, double-blind, placebo-controlled pivotal trial called HER2CLIMB is comparing tucatinib vs. placebo, each in combination with capecitabine and trastuzumab in patients with pretreated, unresectable, locally advanced or metastatic HER2+ breast cancer, including patients with or without brain metastases.

"The combination of tucatinib and T-DM1 in the phase 1b clinical trial was tolerable and appeared to show antitumor activity among heavily pretreated patients with HER2+ metastatic breast cancer with and without brain metastases," said Virginia Borges, M.D., Deputy Head of the Division of Medical Oncology and the Robert F. & Patricia Young Endowed Chair in Young Women’s Breast Cancer Research at the University of Colorado School of Medicine. "Based on these data, tucatinib may have the potential to be a new therapeutic option for these patients and warrants further investigation."

The manuscript entitled "Tucatinib combined with ado-trastuzumab emtansine in advanced HER2-positive metastatic breast cancer: A phase 1b open-label clinical trial" was published in the July print edition of JAMA Oncology.

This phase 1b, open-label dose escalation and expansion cohort study of tucatinib in combination with T-DM1 enrolled 57 patients with HER2+ breast cancer. The objective of the study was to assess the safety, tolerability, pharmacokinetics and antitumor activity, and to determine the recommended phase 2 dose of tucatinib in combination with T-DM1. Participants in the study previously received a median of two prior HER2-directed therapies.

Data from the phase 1b study of tucatinib and T-DM1 (n=57) included:

Median PFS was 8.2 months.
ORR was 47 percent (n=34/50).
The combination of tucatinib and T-DM1 was well-tolerated and the majority of adverse events were grade 1.
About Tucatinib

Tucatinib is an investigational, orally bioavailable, potent tyrosine kinase inhibitor that is highly selective for HER2 without significant inhibition of EGFR. Inhibition of EGFR has been associated with significant toxicities, including skin rash and diarrhea. Tucatinib has shown activity as a single agent and in combination with both chemotherapy and other HER2 directed agents such as trastuzumab.1,2 Studies of tucatinib in these combinations have shown activity both systemically and in brain metastases. HER2 is a growth factor receptor that is overexpressed in multiple cancers, including breast, ovarian and gastric cancers. HER2 mediates cell growth, differentiation and survival. Tumors that overexpress HER2 are more aggressive and historically have been associated with poor overall survival, compared with HER2-negative cancers. Tucatinib has been granted orphan drug designation by the U.S. Food and Drug Administration ("FDA") for the treatment of breast cancer patients with brain metastases.

About HER2-Positive Metastatic Breast Cancer

Patients with HER2-positive breast cancer have tumors with high levels of a protein called human epidermal growth factor receptor 2 (HER2), which promotes the aggressive spread of cancer cells. The American Cancer Society estimates 268,670 new cases of invasive breast cancer will be diagnosed in the U.S. in 2018. Approximately 15 to 20 percent of breast cancers are HER2-positive.3 Historically, HER2 disease has been associated with shorter survival times as well as a higher risk of recurrence and CNS disease (brain metastases). Approximately 30 to 50 percent of HER2-positive breast cancer patients develop brain metastases over time.4,5 Over the past two decades, the approvals of four targeted treatments (trastuzumab, pertuzumab, lapatinib and T-DM1) have led to improved time to progression and survival rates of patients with HER2-positive breast cancer. Despite these advances, there is still a significant need for new therapies that can impact metastatic disease, including brain metastases, and be tolerated for longer periods of time.

On July 11, 2018 Merck (NYSE:MRK), known as MSD outside the United States and Canada, reported that the U.S. Food and Drug Administration (FDA) has accepted and granted priority review for a new supplemental Biologics License Application (sBLA) seeking approval for KEYTRUDA, Merck’s anti-PD-1 therapy, as a treatment for previously treated patients with advanced hepatocellular carcinoma (HCC) (Press release, Merck & Co, JUL 11, 2018, View Source [SID1234527643]). This sBLA, which is seeking accelerated approval for this new indication, is based on data from the Phase 2 KEYNOTE-224 trial, which were recently presented at the 2018 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting and published simultaneously in The Lancet Oncology. The FDA has set a Prescription Drug User Fee Act (PDUFA), or target action, date of Nov. 9, 2018.

"There continues to be a significant need for new options in the treatment of advanced hepatocellular carcinoma, which is the most common type of liver cancer," said Dr. Scot Ebbinghaus, vice president, clinical research, Merck Research Laboratories. "The data supporting our application provide a clear rationale for the advancement of the KEYTRUDA clinical program for hepatocellular carcinoma, and we are grateful for the opportunity to work with the FDA to potentially bring KEYTRUDA to patients living with this difficult-to-treat cancer."

Merck’s broad immuno-oncology clinical development program includes more than 10 Merck-sponsored studies investigating KEYTRUDA in gastrointestinal cancers, including HCC. In addition to KEYNOTE-224, Merck has two ongoing pivotal Phase 3 studies, KEYNOTE-240 and KEYNOTE-394, evaluating KEYTRUDA as monotherapy in second-line HCC, as well as ongoing trials investigating KEYTRUDA in combination with other treatments including LENVIMA.

About Hepatocellular Carcinoma (HCC)

Hepatocellular carcinoma (HCC) is the most common type of liver cancer in adults. In the U.S., the incidence of liver cancer has more than tripled since 1980, and it is estimated that 42,200 new cases of liver cancer will be diagnosed this year. Risk factors for liver cancer include gender, ethnicity, chronic viral hepatitis (Hep-B or Hep-C) infection, cirrhosis, alcohol use and metabolic syndrome. Hepatocellular carcinoma – which is frequently diagnosed at an advanced stage – has one of the highest mortality rates of solid cancers, with a five-year survival rate of less than 15 percent.

About KEYTRUDA (pembrolizumab) Injection, 100mg

KEYTRUDA is an anti-PD-1 therapy that works by increasing the ability of the body’s immune system to help detect and fight tumor cells. KEYTRUDA is a humanized monoclonal antibody that blocks the interaction between PD-1 and its ligands, PD-L1 and PD-L2, thereby activating T lymphocytes which may affect both tumor cells and healthy cells.

Merck has the industry’s largest immuno-oncology clinical research program, which currently involves more than 750 trials studying KEYTRUDA across a wide variety of cancers and treatment settings. The KEYTRUDA clinical program seeks to understand the role of KEYTRUDA across cancers and the factors that may predict a patient’s likelihood of benefitting from treatment with KEYTRUDA, including exploring several different biomarkers.

Selected Important Safety Information for KEYTRUDA

KEYTRUDA can cause immune-mediated pneumonitis, including fatal cases. Pneumonitis occurred in 94 (3.4%) of 2799 patients receiving KEYTRUDA, including Grade 1 (0.8%), 2 (1.3%), 3 (0.9%), 4 (0.3%), and 5 (0.1%) pneumonitis, and occurred more frequently in patients with a history of prior thoracic radiation (6.9%) compared to those without (2.9%). Monitor patients for signs and symptoms of pneumonitis. Evaluate suspected pneumonitis with radiographic imaging. Administer corticosteroids for Grade 2 or greater pneumonitis. Withhold KEYTRUDA for Grade 2; permanently discontinue KEYTRUDA for Grade 3 or 4 or recurrent Grade 2 pneumonitis.

KEYTRUDA can cause immune-mediated colitis. Colitis occurred in 48 (1.7%) of 2799 patients receiving KEYTRUDA, including Grade 2 (0.4%), 3 (1.1%), and 4 (<0.1%) colitis. Monitor patients for signs and symptoms of colitis. Administer corticosteroids for Grade 2 or greater colitis. Withhold KEYTRUDA for Grade 2 or 3; permanently discontinue KEYTRUDA for Grade 4 colitis.

KEYTRUDA can cause immune-mediated hepatitis. Hepatitis occurred in 19 (0.7%) of 2799 patients receiving KEYTRUDA, including Grade 2 (0.1%), 3 (0.4%), and 4 (<0.1%) hepatitis. Monitor patients for changes in liver function. Administer corticosteroids for Grade 2 or greater hepatitis and, based on severity of liver enzyme elevations, withhold or discontinue KEYTRUDA.

KEYTRUDA can cause hypophysitis. Hypophysitis occurred in 17 (0.6%) of 2799 patients receiving KEYTRUDA, including Grade 2 (0.2%), 3 (0.3%), and 4 (<0.1%) hypophysitis. Monitor patients for signs and symptoms of hypophysitis (including hypopituitarism and adrenal insufficiency). Administer corticosteroids and hormone replacement as clinically indicated. Withhold KEYTRUDA for Grade 2; withhold or discontinue for Grade 3 or 4 hypophysitis.

KEYTRUDA can cause thyroid disorders, including hyperthyroidism, hypothyroidism, and thyroiditis. Hyperthyroidism occurred in 96 (3.4%) of 2799 patients receiving KEYTRUDA, including Grade 2 (0.8%) and 3 (0.1%) hyperthyroidism. Hypothyroidism occurred in 237 (8.5%) of 2799 patients receiving KEYTRUDA, including Grade 2 (6.2%) and 3 (0.1%) hypothyroidism. The incidence of new or worsening hypothyroidism was higher in patients with HNSCC, occurring in 28 (15%) of 192 patients with HNSCC, including Grade 3 (0.5%) hypothyroidism. Thyroiditis occurred in 16 (0.6%) of 2799 patients receiving KEYTRUDA, including Grade 2 (0.3%) thyroiditis. Monitor patients for changes in thyroid function (at the start of treatment, periodically during treatment, and as indicated based on clinical evaluation) and for clinical signs and symptoms of thyroid disorders. Administer replacement hormones for hypothyroidism and manage hyperthyroidism with thionamides and beta-blockers as appropriate. Withhold or discontinue KEYTRUDA for Grade 3 or 4 hyperthyroidism.

KEYTRUDA can cause type 1 diabetes mellitus, including diabetic ketoacidosis, which have been reported in 6 (0.2%) of 2799 patients. Monitor patients for hyperglycemia or other signs and symptoms of diabetes. Administer insulin for type 1 diabetes, and withhold KEYTRUDA and administer antihyperglycemics in patients with severe hyperglycemia.

KEYTRUDA can cause immune-mediated nephritis. Nephritis occurred in 9 (0.3%) of 2799 patients receiving KEYTRUDA, including Grade 2 (0.1%), 3 (0.1%), and 4 (<0.1%) nephritis. Monitor patients for changes in renal function. Administer corticosteroids for Grade 2 or greater nephritis. Withhold KEYTRUDA for Grade 2; permanently discontinue KEYTRUDA for Grade 3 or 4 nephritis.

Immune-mediated rashes, including Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN) (some cases with fatal outcome), exfoliative dermatitis, and bullous pemphigoid, can occur. Monitor patients for suspected severe skin reactions and based on the severity of the adverse reaction, withhold or permanently discontinue KEYTRUDA and administer corticosteroids. For signs or symptoms of SJS or TEN, withhold KEYTRUDA and refer the patient for specialized care for assessment and treatment. If SJS or TEN is confirmed, permanently discontinue KEYTRUDA.

Immune-mediated adverse reactions, which may be severe or fatal, can occur in any organ system or tissue in patients receiving KEYTRUDA. While immune-mediated adverse reactions usually occur during treatment with PD-1/PD-L1 blocking antibodies, they may occur after discontinuation of treatment. For suspected immune-mediated adverse reactions, ensure adequate evaluation to confirm etiology or exclude other causes. Based on the severity of the adverse reaction, withhold KEYTRUDA and administer corticosteroids. Upon improvement to Grade 1 or less, initiate corticosteroid taper and continue to taper over at least 1 month. Based on limited data from clinical studies in patients whose immune-related adverse reactions could not be controlled with corticosteroid use, administration of other systemic immunosuppressants can be considered. Resume KEYTRUDA when the adverse reaction remains at Grade 1 or less following corticosteroid taper. Permanently discontinue KEYTRUDA for any Grade 3 immune-mediated adverse reaction that recurs and for any life-threatening immune-mediated adverse reaction.

The following clinically significant immune-mediated adverse reactions occurred in less than 1% (unless otherwise indicated) of 2799 patients: arthritis (1.5%), uveitis, myositis, Guillain-Barré syndrome, myasthenia gravis, vasculitis, pancreatitis, hemolytic anemia, sarcoidosis, and encephalitis. In addition, myelitis and myocarditis were reported in other clinical trials, including cHL, and postmarketing use.

Solid organ transplant rejection has been reported in postmarketing use of KEYTRUDA. Treatment with KEYTRUDA may increase the risk of rejection in solid organ transplant recipients. Consider the benefit of treatment with KEYTRUDA vs the risk of possible organ rejection in these patients.

KEYTRUDA can cause severe or life-threatening infusion-related reactions, including hypersensitivity and anaphylaxis, which have been reported in 6 (0.2%) of 2799 patients. Monitor patients for signs and symptoms of infusion-related reactions, including rigors, chills, wheezing, pruritus, flushing, rash, hypotension, hypoxemia, and fever. For Grade 3 or 4 reactions, stop infusion and permanently discontinue KEYTRUDA.

Immune-mediated complications, including fatal events, occurred in patients who underwent allogeneic hematopoietic stem cell transplantation (HSCT) after treatment with KEYTRUDA. Of 23 patients with cHL who proceeded to allogeneic HSCT after KEYTRUDA, 6 developed graft-versus-host disease (GVHD) (one fatal case), and 2 developed severe hepatic veno-occlusive disease (VOD) after reduced-intensity conditioning (one fatal case). Cases of fatal hyperacute GVHD after allogeneic HSCT have also been reported in patients with lymphoma who received a PD-1 receptor–blocking antibody before transplantation. Follow patients closely for early evidence of transplant-related complications such as hyperacute GVHD, Grade 3 to 4 acute GVHD, steroid-requiring febrile syndrome, hepatic VOD, and other immune-mediated adverse reactions, and intervene promptly.

In patients with a history of allogeneic HSCT, acute GVHD, including fatal GVHD, has been reported after treatment with KEYTRUDA. Patients who experienced GVHD after their transplant procedure may be at increased risk for GVHD after KEYTRUDA. Consider the benefit of KEYTRUDA vs the risk of GVHD in these patients.

In clinical trials in patients with multiple myeloma, the addition of KEYTRUDA to a thalidomide analogue plus dexamethasone resulted in increased mortality. Treatment of these patients with a PD-1 or PD-L1 blocking antibody in this combination is not recommended outside of controlled clinical trials.

Based on its mechanism of action, KEYTRUDA can cause fetal harm when administered to a pregnant woman. If used during pregnancy, or if the patient becomes pregnant during treatment, apprise the patient of the potential hazard to a fetus. Advise females of reproductive potential to use highly effective contraception during treatment and for 4 months after the last dose of KEYTRUDA.

In KEYNOTE-006, KEYTRUDA was discontinued due to adverse reactions in 9% of 555 patients with advanced melanoma; adverse reactions leading to discontinuation in more than one patient were colitis (1.4%), autoimmune hepatitis (0.7%), allergic reaction (0.4%), polyneuropathy (0.4%), and cardiac failure (0.4%). Adverse reactions leading to interruption of KEYTRUDA occurred in 21% of patients; the most common (≥1%) was diarrhea (2.5%). The most common adverse reactions with KEYTRUDA vs ipilimumab were fatigue (28% vs 28%), diarrhea (26% with KEYTRUDA), rash (24% vs 23%), and nausea (21% with KEYTRUDA).

The most frequent serious adverse reactions reported in at least 2% of patients were pneumonia, dyspnea, confusional state, vomiting, pleural effusion, and respiratory failure. The most common adverse reactions (reported in at least 20% of patients) were fatigue, decreased appetite, and dyspnea. Adverse reactions occurring in patients with HNSCC were generally similar to those occurring in patients with melanoma or NSCLC, with the exception of increased incidences of facial edema (10% all Grades; 2.1% Grades 3 or 4) and new or worsening hypothyroidism.

In KEYNOTE-087, KEYTRUDA was discontinued due to adverse reactions in 5% of 210 patients with cHL, and treatment was interrupted due to adverse reactions in 26% of patients. Fifteen percent (15%) of patients had an adverse reaction requiring systemic corticosteroid therapy. Serious adverse reactions occurred in 16% of patients. The most frequent serious adverse reactions (≥1%) included pneumonia, pneumonitis, pyrexia, dyspnea, GVHD, and herpes zoster. Two patients died from causes other than disease progression; one from GVHD after subsequent allogeneic HSCT and one from septic shock. The most common adverse reactions (occurring in ≥20% of patients) were fatigue (26%), pyrexia (24%), cough (24%), musculoskeletal pain (21%), diarrhea (20%), and rash (20%).

The most common adverse reactions (in ≥20% of patients) were fatigue (38%), musculoskeletal pain (24%), decreased appetite (22%), constipation (21%), rash (21%), and diarrhea (20%). Eighteen patients (5%) died from causes other than disease progression. Five patients (1.4%) who were treated with KEYTRUDA experienced sepsis which led to death, and 3 patients (0.8%) experienced pneumonia which led to death. Adverse reactions leading to interruption of KEYTRUDA occurred in 22% of patients; the most common (≥1%) were liver enzyme increase, diarrhea, urinary tract infection, acute kidney injury, fatigue, joint pain, and pneumonia. Serious adverse reactions occurred in 42% of patients, the most frequent (≥2%) of which were urinary tract infection, hematuria, acute kidney injury, pneumonia, and urosepsis.

In KEYNOTE-045, KEYTRUDA was discontinued due to adverse reactions in 8% of 266 patients with locally advanced or metastatic urothelial carcinoma. The most common adverse reaction resulting in permanent discontinuation of KEYTRUDA was pneumonitis (1.9%). Adverse reactions leading to interruption of KEYTRUDA occurred in 20% of patients; the most common (≥1%) were urinary tract infection (1.5%), diarrhea (1.5%), and colitis (1.1%). The most common adverse reactions (≥20%) in patients who received KEYTRUDA vs those who received chemotherapy were fatigue (38% vs 56%), musculoskeletal pain (32% vs 27%), pruritus (23% vs 6%), decreased appetite (21% vs 21%), nausea (21% vs 29%), and rash (20% vs 13%). Serious adverse reactions occurred in 39% of KEYTRUDA-treated patients, the most frequent (≥2%) of which were urinary tract infection, pneumonia, anemia, and pneumonitis.

In KEYNOTE-158, KEYTRUDA was discontinued due to adverse reactions in 8% of 98 patients (in Cohort E) with recurrent or metastatic cervical cancer. Serious adverse reactions occurred in 39% of patients receiving KEYTRUDA. The most frequent serious adverse reactions reported included anemia (7%), fistula, hemorrhage, and infections [except urinary tract infections] (4.1% each). The most common adverse reactions (occurring in ≥20% of patients) were fatigue (43%), musculoskeletal pain (27%), diarrhea (23%), pain and abdominal pain (22% each), and decreased appetite (21%).

It is not known whether KEYTRUDA is excreted in human milk. Because many drugs are excreted in human milk, instruct women to discontinue nursing during treatment with KEYTRUDA and for 4 months after the final dose.

There is limited experience in pediatric patients. In a study, 40 pediatric patients (16 children aged 2 years to younger than 12 years and 24 adolescents aged 12 years to 18 years) with advanced melanoma, lymphoma, or PD-L1–positive advanced, relapsed, or refractory solid tumors were administered KEYTRUDA 2 mg/kg every 3 weeks. Patients received KEYTRUDA for a median of 3 doses (range 1–17 doses), with 34 patients (85%) receiving 2 doses or more. The safety profile in these pediatric patients was similar to that seen in adults treated with KEYTRUDA. Toxicities that occurred at a higher rate (≥15% difference) in these patients when compared to adults under 65 years of age were fatigue (45%), vomiting (38%), abdominal pain (28%), hypertransaminasemia (28%), and hyponatremia (18%).

"Bristol-Myers Squibb is pleased to bring forward Opdivo plus Yervoy as the first I-O/I-O combination therapy to be approved in this type of colorectal cancer," said Ian M. Waxman, M.D., development lead, gastrointestinal cancers, Bristol-Myers Squibb. "Our commitment to studying Opdivo plus Yervoy, which target distinct but complementary immune pathways, results from our strong belief that rational combinations in biomarker-selected populations may improve clinical benefit for patients."

Opdivo + Yervoy is associated with the following Warnings and Precautions: immune-mediated pneumonitis, colitis, hepatitis, endocrinopathies, nephritis and renal dysfunction, skin adverse reactions, encephalitis, other adverse reactions; infusion reactions; and embryo-fetal toxicity. Please see the Important Safety Information section below, including Boxed WARNING for Yervoy regarding immune-mediated adverse reactions, as well as additional information on CheckMate -142.1,2

Today’s approved indication was based on data from the ongoing Phase 2 CheckMate -142 study evaluating the Opdivo + Yervoy combination in patients with MSI-H or dMMR mCRC previously treated with a fluoropyrimidine-, oxaliplatin- or irinotecan-based chemotherapy.1,3,4 The application was granted Priority Review and Breakthrough Therapy Designation by the FDA.

The Opdivo + Yervoy cohort of the CheckMate -142 trial enrolled MSI-H/dMMR mCRC patients who had received at least one prior line of therapy for metastatic disease, and efficacy was analyzed for both patients who had received prior treatment with a fluoropyrimidine, oxaliplatin and irinotecan (82 of the total 119 patients) as well as for all enrolled patients.1

Among the 82 patients who received prior treatment with a fluoropyrimidine, oxaliplatin and irinotecan, 46% (95% CI: 35-58; n = 38/82) responded to treatment with Opdivo + Yervoy as assessed by Independent Radiographic Review Committee (IRRC).1
The percentage of these patients with a complete response was 3.7% (n = 3/82), and the percentage of patients with a partial response was 43% (n = 35/82).1 Among these 38 responders, the median DOR was not reached (range: 1.9-23.2+ months); 89% of those patients had responses of six months or longer, and 21% had responses of 12 months or longer.1,5,6 This trial is ongoing.3
Among all enrolled patients, 49% (95% CI: 39-58; n = 58/119) responded to treatment with Opdivo + Yervoy; 4.2% (n = 5/119) experienced a complete response, while 45% (n = 53/119) experienced a partial response.1 Among these 58 responders, the median DOR was not reached (range: 1.9-23.2+ months)5,6; 83% of those patients had responses of six months or longer, and 19% had responses of 12 months or longer.1 In the combination cohort, 51 of 58 responders were ongoing at the time of database lock; 78% of these ongoing responders had not reached 12 months of follow-up from the date of onset of response.1
The recommended dosing schedule includes the Opdivo + low-dose Yervoy combination (Opdivo 3 mg/kg, administered as an I.V. infusion over 30 minutes, followed by Yervoy 1 mg/kg, administered as an I.V. infusion over 30 minutes, on the same day, every three weeks for four doses), followed by Opdivo maintenance therapy (240 mg, administered as an I.V. infusion over 30 minutes, every two weeks) after completion of four doses of the combination until disease progression or unacceptable toxicity.1 Please review the U.S. Full Prescribing Information for Yervoy prior to initiation.

In the Opdivo + Yervoy cohort of CheckMate -142, 86% of patients received all four doses of Opdivo + Yervoy.7 Opdivo was discontinued in 13% of patients and delayed in 45% of patients due to an adverse reaction.1 Serious adverse reactions occurred in 47% of patients.1

"Metastatic colorectal cancers with dMMR or MSI-H biomarkers can be difficult to treat and some patients may need additional options," said Heinz-Josef Lenz, M.D., FACP, L. Terrence Lanni Chair in Gastrointestinal Cancer Research, Keck School of Medicine of University of Southern California and principal investigator of the study at USC Norris Comprehensive Cancer Center. "The FDA’s approval of an I-O/I-O combination provides us with an encouraging approach to address this challenging disease in patients who have progressed following treatment with three standard chemotherapy options."

The Opdivo + Yervoy combination is also approved in two other tumor types. The Opdivo (3 mg/kg) + low-dose Yervoy (1 mg/kg) combination is approved for previously untreated patients with intermediate- or poor-risk advanced renal cell carcinoma. Opdivo (1 mg/kg) + Yervoy (3 mg/kg) is approved for patients with unresectable or metastatic melanoma under accelerated approval based on progression-free survival. Opdivo as a single agent is approved for the treatment of adult and pediatric (12 years and older) patients with MSI-H or dMMR metastatic colorectal cancer that has progressed following treatment with a fluoropyrimidine, oxaliplatin and irinotecan under accelerated approval based on ORR and DOR. Continued approval for these accelerated approval indications may be contingent upon verification and description of clinical benefit in the confirmatory trials. The infusion time for each indication differs, please see U.S. Full Prescribing Information for Opdivo and Yervoy for details.1

Approval Based on CheckMate -142 Trial

CheckMate -142 included a multicenter, non-randomized, multiple-parallel cohort, open-label study investigating Opdivo + Yervoy in patients with locally determined dMMR or MSI-H mCRC whose disease had progressed during or after prior treatment with a fluoropyrimidine-, oxaliplatin- or irinotecan-based chemotherapy.1,8 In the combination cohort, patients received Opdivo 3 mg/kg with Yervoy 1 mg/kg every three weeks for four doses, followed by Opdivo 3 mg/kg as a single agent every two weeks.1 Treatment continued until unacceptable toxicity or radiographic progression.1 Tumor assessments were conducted every six weeks for the first 24 weeks and every 12 weeks thereafter.1 Efficacy outcome measures included ORR as assessed by IRRC using Response Evaluation Criteria in Solid Tumors (RECIST v1.1) and DOR.1 Data from this study were presented in January at the 2018 Gastrointestinal Cancers Symposium and published simultaneously in the Journal of Clinical Oncology.

Select Safety Profile for the CheckMate -142 Trial

The most frequent serious adverse reactions reported in at least 2% of patients were colitis/diarrhea, hepatic events, abdominal pain, acute kidney injury, pyrexia, and dehydration.1 The most common adverse reactions (reported in at least 20% of patients) were fatigue (49%), diarrhea (45%), pyrexia (36%), musculoskeletal pain (36%), abdominal pain (30%), pruritus (28%), nausea (26%), rash (25%), decreased appetite (20%), and vomiting (20%).1

About MSI-H or dMMR Colorectal Cancer

Colorectal cancer (CRC) is cancer that develops in the colon or the rectum, which are part of the body’s digestive or gastrointestinal system.10 In the United States, CRC is the third most common cancer.10 In 2018, it is estimated that there will be approximately 140,000 new cases of the disease and that it will be the third leading cause of cancer-related deaths among men and women combined.10

DNA mismatch repair deficiency (dMMR) occurs when the proteins that repair mismatch errors in DNA replication are missing or non-functional, leading to microsatellite instability-high (MSI-H) tumors.11,12 Approximately 5% of metastatic CRC patients have dMMR or MSI-H tumors.13 Patients with these biomarkers are less likely to benefit from conventional chemotherapy and typically have a poor prognosis.11,13,14

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.

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 1 mg/kg with YERVOY 3 mg/kg (0.2%) after 1.7 months of exposure. Encephalitis occurred in one RCC patient receiving OPDIVO 3 mg/kg with YERVOY 1 mg/kg (0.2%) after approximately 4 months of exposure. Encephalitis occurred in one MSI-H/dMMR mCRC patient (0.8%) receiving OPDIVO 3 mg/kg with YERVOY 1 mg/kg after 15 days of exposure.

Other Immune-Mediated Adverse Reactions

Based on the severity of the adverse reaction, permanently discontinue or withhold OPDIVO, administer high-dose corticosteroids, and if appropriate, initiate hormone-replacement therapy. Across clinical trials of OPDIVO monotherapy or in combination with YERVOY, the following clinically significant immune-mediated adverse reactions, some with fatal outcome, occurred in <1.0% of patients receiving OPDIVO: myocarditis, rhabdomyolysis, myositis, 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), motor dysfunction, vasculitis, aplastic anemia, pericarditis, and myasthenic syndrome.

If uveitis occurs in combination with other immune-mediated adverse reactions, consider a Vogt-Koyanagi-Harada-like syndrome, which has been observed in patients receiving OPDIVO and may require treatment with systemic steroids to reduce the risk of permanent vision loss.

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 as a 60-minute infusion, infusion-related reactions occurred in 6.4% (127/1994) of patients. In a separate study in which patients received OPDIVO monotherapy as a 60-minute infusion or a 30-minute infusion, infusion-related reactions occurred in 2.2% (8/368) and 2.7% (10/369) of patients, respectively. Additionally, 0.5% (2/368) and 1.4% (5/369) of patients, respectively, experienced adverse reactions within 48 hours of infusion that led to dose delay, permanent discontinuation or withholding of OPDIVO. In patients receiving OPDIVO 1 mg/kg with YERVOY 3 mg/kg every 3 weeks, infusion-related reactions occurred in 2.5% (10/407) of patients. In RCC patients receiving OPDIVO 3 mg/kg with YERVOY 1 mg/kg, infusion-related reactions occurred in 5.1% (28/547) of patients. In MSI-H/dMMR mCRC patients receiving OPDIVO 3 mg/kg with YERVOY 1 mg/kg, infusion-related reactions occurred in 4.2% (5/119) of patients.

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 breastfeeding during treatment with YERVOY and for 3 months following the final dose.

Serious Adverse Reactions

In Checkmate 067, serious adverse reactions (73% and 37%), adverse reactions leading to permanent discontinuation (43% and 14%) or to dosing delays (55% and 28%), and Grade 3 or 4 adverse reactions (72% and 44%) all occurred more frequently in the OPDIVO plus YERVOY arm (n=313) relative to the OPDIVO arm (n=313). The most frequent (≥10%) serious adverse reactions in the OPDIVO plus YERVOY arm and the OPDIVO arm, respectively, were diarrhea (13% and 2.6%), colitis (10% and 1.6%), and pyrexia (10% and 0.6%). In Checkmate 214, serious adverse reactions occurred in 59% of patients receiving OPDIVO plus YERVOY and in 43% of patients receiving sunitinib. The most frequent serious adverse reactions reported in ≥2% of patients were diarrhea, pyrexia, pneumonia, pneumonitis, hypophysitis, acute kidney injury, dyspnea, adrenal insufficiency, and colitis; in patients treated with sunitinib, they were pneumonia, pleural effusion, and dyspnea. In Checkmate 142 in MSI-H/dMMR mCRC patients receiving OPDIVO with YERVOY, serious adverse reactions occurred in 47% of patients. The most frequent serious adverse reactions reported in ≥2% of patients were colitis/diarrhea, hepatic events, abdominal pain, acute kidney injury, pyrexia, and dehydration.

On July 10, 2018 Applied BioMath (www.appliedbiomath.com), the industry-leader in applying mechanistic modeling, simulation, and analysis to de-risk and accelerate drug research and development, reported a collaboration with Revitope for an in-vitro and human mechanistic PK/PD modeling of Revitope’s bispecific T Cell Engaging Antibody Circuits (TEAC) targeting solid tumors (Press release, Applied BioMath, JUL 10, 2018, View Source [SID1234633659]). "TEAC are designed to increase tumor specificity and launch an immune activation only when bound to the cancer cell surface. This innovative engineering approach has the potential to unleash potent immune responses that are focused entirely on the tumor," said Werner Meier, CSO and acting CEO of Revitope Oncology. "Our goal in this collaboration is to leverage Applied BioMath’s modeling and analyses capabilities to identify TEAC drug properties that drive the potential for a better therapeutic index and ideally more efficacy in immuno-oncology."

Applied BioMath employs a rigorous fit-for-purpose model development process, referred to as Model-Aided Drug Invention (MADI), which aims to quantitatively integrate knowledge about therapeutics with an understanding of its mechanism of action in the context of human disease mechanisms. Their MADI approach employs proprietary algorithms and software that were designed specifically for mechanistic PK/PD modeling. "Our mechanistic modeling approach allows our collaborators to assess the feasibility of their therapeutic much more quickly than if they were to rely on experiments alone," said Dr. John Burke, PhD, Co-Founder, President, and CEO of Applied BioMath. "They’ll be able to quickly answer strategic questions about the ideal properties for their therapeutic concept and help accelerate development in Lead Generation and by prioritizing experiments, thus helping them get into the clinical faster and for less money with potentially a BIC therapeutic, giving themselves a much higher chance of clinical success and maximizing R&D ROI."

Buparlisib (BKM120) is an oral pan-PI3K inhibitor that targets all class 1 PI3K isoforms and is active in both hematologic malignancies and solid tumors. It has shown promising efficacy in combination with paclitaxel in head and neck squamous cell carcinoma (HNSCC) and has received a Fast-Track designation from the FDA.

"Combination of buparlisib and paclitaxel demonstrated improved clinical efficacy with a manageable safety profile in patients with HNSCC compared to paclitaxel alone," said Dr. Lars Birgerson, Chief Development Officer of Adlai Nortye and President & CEO of Adlai Nortye USA Inc. "We believe that buparlisib will be another key component in furthering development of our oncology pipeline, and it has great potential for future application in cancer treatment."

"Buparlisib has been extensively profiled in breast cancer and other tumor types. Buparlisib when combined with other therapies has shown impressive anti-cancer efficacy in HNSCC," said Carsten Lu, CEO of Adlai Nortye, "It has very good market prospects when combined with paclitaxel, and we are planning to carry out clinical trials of combination of buparlisib and immune check point inhibitor treatment."
