Pfizer Receives Positive CHMP Opinion for Two Hematology Medicines, MYLOTARG™ and BOSULIF®

On February 23, 2018 Pfizer Inc. (NYSE:PFE) reported that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has adopted positive opinions recommending that two Pfizer hematology medicines be granted marketing authorizations in the European Union (EU) (Press release, Pfizer, FEB 23, 2018, View Source [SID1234524144]). MYLOTARG (gemtuzumab ozogamicin) in combination with daunorubicin and cytarabine has been granted a positive opinion for the treatment of patients age 15 years and above with previously untreated, de novo, CD33-positive acute myeloid leukemia (AML), except acute promyelocytic leukemia (APL). BOSULIF (bosutinib) has been granted a positive opinion for the treatment of adults with newly diagnosed chronic phase Philadelphia chromosome-positive chronic myelogenous leukemia (Ph+ CML). The CHMP’s opinions for both medicines will now be reviewed separately by the European Commission (EC).

"There is an urgent need to improve outcomes for leukemia patients in Europe," said Mace Rothenberg, M.D., chief development officer, Oncology, Pfizer Global Product Development. "If approved, the addition of MYLOTARG to standard chemotherapy will provide an important new treatment option for patients with acute myeloid leukemia who would typically be treated with chemotherapy alone. Additionally, the potential expansion of the approved use of BOSULIF to include first-line therapy expands the treatment options for adult patients with newly diagnosed chronic myelogenous leukemia."

The Marketing Authorization Application (MAA) for MYLOTARG was based on data from an investigator-led, Phase 3, randomized, open-label study (ALFA-0701) in previously untreated, de novo patients.

BOSULIF currently has conditional marketing authorization in Europe related to the initial marketing authorization. The Type II Variation application for BOSULIF for adults with newly diagnosed chronic phase Ph+ CML was based on results from BFORE (Bosutinib trial in First line chrOnic myelogenous leukemia tREatment), a randomized multicenter, multinational, open-label, Phase 3, head-to-head study of BOSULIF 400 mg versus imatinib 400 mg, a current standard of care.

Pfizer and Avillion entered into an exclusive collaborative development agreement in 2014 to conduct the BFORE trial. Under the terms of the agreement, Avillion provided funding for the trial to generate the clinical data used to support this application and other potential regulatory filings for marketing authorization for BOSULIF as first-line treatment for patients with chronic phase Ph+ CML. Pfizer retains all rights to commercialize BOSULIF globally.

IMPORTANT MYLOTARG (gemtuzumab ozogamicin) SAFETY INFORMATION FROM THE U.S. PRESCRIBING INFORMATION

WARNING: Hepatotoxicity, including severe or fatal hepatic veno-occlusive disease (VOD), also known as sinusoidal obstruction syndrome (SOS), has been reported in association with the use of MYLOTARG as a single agent, and as part of a combination chemotherapy regimen. Monitor frequently for signs and symptoms of VOD after treatment with MYLOTARG.

Hepatotoxicity, Including Veno-occlusive Liver Disease (VOD): An increased risk of VOD was observed in patients with moderate/severe hepatic impairment and patients who received MYLOTARG either before or after HSCT. Assess ALT, AST, total bilirubin, and alkaline phosphatase prior to each dose of MYLOTARG. After treatment with MYLOTARG, monitor frequently for signs and symptoms of VOD; these may include elevations in ALT, AST, and total bilirubin, hepatomegaly, rapid weight gain, and ascites. Monitoring only total bilirubin may not identify all patients at risk of VOD. For patients who develop abnormal liver tests, more frequent monitoring of liver tests and clinical signs and symptoms of hepatotoxicity is recommended. For patients who proceed to HSCT, monitor liver tests frequently during the post-HSCT period, as appropriate. Manage signs or symptoms of hepatic toxicity by dose interruption or discontinuation of MYLOTARG. In patients who experience VOD, discontinue MYLOTARG and treat according to standard medical practice.

Infusion-Related Reactions (Including Anaphylaxis): Life-threatening or fatal infusion-related reactions can occur during or within 24 hours following infusion of MYLOTARG. Signs and symptoms of infusion-related reactions may include fever, chills, hypotension, tachycardia, hypoxia, and respiratory failure. Premedicate prior to MYLOTARG infusion. Monitor vital signs frequently during infusion. Interrupt infusion immediately for patients who develop evidence of infusion reaction, especially dyspnea, bronchospasm, or hypotension. Monitor patients during and for at least 1 hour after the end of the infusion or until signs and symptoms completely resolve. Discontinue use of MYLOTARG in patients who develop signs or symptoms of anaphylaxis, including severe respiratory symptoms or clinically significant hypotension.

Hemorrhage: MYLOTARG is myelosuppressive and can cause fatal or life-threatening hemorrhage due to prolonged thrombocytopenia. Assess blood counts prior to each dose of MYLOTARG and monitor blood counts frequently after treatment with MYLOTARG until resolution of cytopenias. Monitor patients for signs and symptoms of bleeding during treatment with MYLOTARG. Manage severe bleeding, hemorrhage, or persistent thrombocytopenia using dose delay or permanent discontinuation of MYLOTARG, and provide supportive care per standard practice.

QT Interval Prolongation: QT interval prolongation has been observed in patients treated with other drugs containing calicheamicin. When administering MYLOTARG to patients who have a history of or predisposition for QTc prolongation, who are taking medicinal products that are known to prolong QT interval, and in patients with electrolyte disturbances, obtain electrocardiograms and electrolytes prior to the start of treatment and as needed during administration.

Adverse Cytogenetics: In a subgroup analysis in ALFA-0701, the addition of MYLOTARG to standard combination chemotherapy did not improve event-free survival in the subgroup of patients having adverse-risk cytogenetics. For patients being treated with MYLOTARG in combination with daunorubicin and cytarabine for newly diagnosed de novo AML, when cytogenetics testing results become available consider whether the potential benefit of continuing treatment with MYLOTARG outweighs the risks for the individual patient.

Embryo-Fetal Toxicity: MYLOTARG can cause embryo-fetal harm when administered to a pregnant woman. Advise patients of reproductive potential to use effective contraception during and for 3 and 6 months following treatment for males and females, respectively. Apprise pregnant women of the potential risk to the fetus. Advise women to contact their healthcare provider if they become pregnant or if pregnancy is suspected during treatment with MYLOTARG.

Adverse Reactions: The most common adverse reactions (greater than 15%) were hemorrhage, infection, fever, nausea, vomiting, constipation, headache, increased AST, increased ALT, rash, and mucositis.

Contraindications: Hypersensitivity to MYLOTARG or any of its components. Reactions have included anaphylaxis.

The full U.S. prescribing information, including BOXED WARNING, for MYLOTARG can be found here.

IMPORTANT BOSULIF (bosutinib) SAFETY INFORMATION FROM THE U.S. PRESCRIBING INFORMATION

Contraindication: History of hypersensitivity to BOSULIF. Reactions have included anaphylaxis. Anaphylactic shock occurred in less than 0.2% of treated patients in single-agent cancer studies with BOSULIF.

Gastrointestinal Toxicity: Diarrhea, nausea, vomiting, and abdominal pain can occur. In the randomized clinical trial of patients with newly diagnosed Ph+ CML, the median time to onset for diarrhea (all grades) among patients in the BOSULIF treatment group (n=268) was 3 days and the median duration per event was 3 days. Among 546 patients in a single-arm study of patients with CML who were resistant or intolerant to prior therapy, median time to onset of diarrhea (all grades) was 2 days, median duration was 2 days, and the median number of episodes per patient was 3 (range 1-268). Monitor and manage patients using standards of care, including antidiarrheals, antiemetics, and/or fluid replacement. Withhold, dose reduce, or discontinue BOSULIF as necessary.

Myelosuppression: Thrombocytopenia, anemia, and neutropenia can occur. Perform complete blood counts weekly for the first month and monthly thereafter, or as clinically indicated. Withhold, dose reduce, or discontinue BOSULIF as necessary.

Hepatic Toxicity: Elevations in serum transaminases (alanine aminotransferase [ALT] and aspartate aminotransferase [AST]) can occur. Perform hepatic enzyme tests at least monthly for the first 3 months and as clinically indicated. In patients with transaminase elevations, monitor liver enzymes more frequently. One case consistent with drug-induced liver injury occurred without alternative causes in a trial of BOSULIF in combination with letrozole. Withhold, dose reduce, or discontinue BOSULIF as necessary. In patients with mild, moderate, or severe hepatic impairment, the recommended starting dose is 200 mg daily.

Renal Toxicity: An on-treatment decline in estimated glomerular filtration rate has occurred in patients treated with BOSULIF. Monitor renal function at baseline and during therapy, with particular attention to patients with preexisting renal impairment or risk factors for renal dysfunction. Consider dose adjustment in patients with baseline and treatment-emergent renal impairment.

Reduce the BOSULIF starting dose in patients with moderate (creatinine clearance [CLcr] 30 to 50 mL/min) or severe (CLcr less than 30 mL/min) renal impairment at baseline. For patients who have declining renal function while on BOSULIF who cannot tolerate the starting dose, follow dose adjustment recommendations for toxicity.

Fluid Retention: Fluid retention can occur with BOSULIF and may cause pericardial effusion, pleural effusion, pulmonary edema, and/or peripheral edema. Among 546 patients in a single-arm study of patients with Ph+ CML who were resistant or intolerant to prior therapy, Grade 3/4 fluid retention was reported in 26 patients (5%). Monitor and manage patients using standards of care. Interrupt, dose reduce, or discontinue BOSULIF as necessary.

Embryofetal Toxicity: BOSULIF can cause fetal harm when administered to a pregnant woman. Women of childbearing potential should be advised of the potential hazard to the fetus. Advise females of reproductive potential to use effective contraceptive measures to prevent pregnancy while being treated with BOSULIF and for at least 1 month after the final dose.

Adverse Reactions: The most common adverse reactions observed in greater than or equal to 20% of patients with newly diagnosed CML were diarrhea, nausea, thrombocytopenia, rash, increased ALT, abdominal pain, and increased AST. The most common Grade 3/4 adverse reactions and laboratory abnormalities observed in greater than 10% of newly diagnosed CML patients were thrombocytopenia and increased ALT.

The most common adverse reactions observed in greater than or equal to 20% of patients with CML who were resistant or intolerant to prior therapy were diarrhea, nausea, abdominal pain, rash, thrombocytopenia, vomiting, anemia, fatigue, pyrexia, cough, headache, ALT, and edema. The most common Grade 3/4 adverse reactions and laboratory abnormalities observed in greater than 10% of patients who were resistant or intolerant to prior therapy were thrombocytopenia, neutropenia, and anemia.

CYP3A Inhibitors and Inducers: Avoid concurrent use with strong or moderate CYP3A inhibitors or strong CYP3A inducers.

Proton Pump Inhibitors: Use short-acting antacids or H2 blockers instead of PPIs to avoid a reduction in BOSULIF exposure. Separate antacid or H2 blocker dosing and BOSULIF dosing by more than 2 hours.

Lactation: Because of the potential for serious adverse reactions in a nursing child, breastfeeding is not recommended during treatment with BOSULIF and for at least 1 month after the last dose.

Please see full U.S. Prescribing Information for BOSULIF here.

ABOUT ACUTE MYELOID LEUKEMIA (AML)

Acute myeloid leukemia is a rapidly progressing, life-threatening blood and bone marrow cancer. 1 If left untreated, patients with AML will die within months, if not weeks, of their disease. AML is the most common type of acute leukemia in adults and accounts for approximately 80% of all cases of acute leukemia.2 About 1/33,000-1/25,000 people are expected to be newly diagnosed with AML in Europe annually.2

ABOUT CHRONIC MYELOGENOUS LEUKEMIA (CML)

Chronic myelogenous leukemia (CML) is a rare blood cancer, which begins in the bone marrow, but often moves into the blood.3 Researchers estimate that by 2020, more than 412,000 people worldwide will be diagnosed with leukemia (all types).4 Across Europe, CML constitutes about 15% of all leukemia and occurs with an incidence of about 1-1.5/100,000.5

About MYLOTARG (gemtuzumab ozogamicin)

MYLOTARG is an antibody-drug conjugate (ADC) composed of the cytotoxic agent calicheamicin, attached to a monoclonal antibody (mAB) targeting CD33, an antigen expressed on the surface of myeloblasts in up to 90 percent of AML patients.6,7,8 When MYLOTARG binds to the CD33 antigen on the cell surface it is absorbed into the cell and calicheamicin is released causing cell death.7,8

MYLOTARG was approved by the U.S. Food and Drug Administration in September 2017 for adults with newly diagnosed CD33-positive AML, and adults and children 2 years and older with relapsed or refractory CD33-positive AML. MYLOTARG was originally approved in 2000 at a higher dose under the FDA’s accelerated approval program for use as a single agent in patients with CD33-positive AML who had experienced their first relapse and were 60 years or older and who were not considered candidates for other cytotoxic chemotherapy. In 2010, Pfizer voluntarily withdrew MYLOTARG in the U.S. after a confirmatory trial failed to show clinical benefit and there was a higher rate of fatal toxicity compared to chemotherapy. MYLOTARG has been available to individual patients through Pfizer’s compassionate use programs.

In addition, MYLOTARG is commercially available in Japan where it has been approved since 2005 for the treatment of patients with relapsed or refractory CD33-positive AML who are not considered candidates for other cytotoxic chemotherapy.

MYLOTARG originates from a collaboration between Pfizer and Celltech, now UCB. Pfizer has sole responsibility for all manufacturing, clinical development and commercialization activities for this molecule.

Pfizer also collaborated with SFJ Pharmaceuticals Group on the registrational program for MYLOTARG.

ABOUT BOSULIF (bosutinib)

BOSULIF (bosutinib) is an oral, once-daily, tyrosine kinase inhibitor (TKI), which inhibits the Bcr-Abl kinase that promotes CML; it is also an inhibitor of Src-family kinases. In the U.S., BOSULIF (bosutinib) is indicated for the treatment of adult patients with newly-diagnosed chronic phase Philadelphia chromosome-positive chronic myelogenous leukemia (Ph+ CML). Continued approval for this indication may be contingent upon verification and confirmation of clinical benefit in an ongoing long-term follow up trial. BOSULIF is also indicated in the U.S for the treatment of adult patients with chronic, accelerated or blast phase Ph+ CML with resistance or intolerance to prior therapy (first approved in September 2012).

In Europe, BOSULIF was granted conditional marketing authorization in March 2013 for the treatment of adult patients with Ph+ CML previously treated with one or more TKIs and for whom imatinib, nilotinib and dasatinib are not considered appropriate treatment options.

Jazz Pharmaceuticals Announces First Patient Enrolled in Phase 2 Clinical Trial Evaluating Defibrotide for the Prevention of Acute Graft-versus-Host Disease

On February 23, 2018 Jazz Pharmaceuticals plc (Nasdaq: JAZZ) reported that the first patient has been enrolled in a Phase 2 clinical trial evaluating the efficacy and safety of defibrotide for the prevention of acute Graft-versus-Host-Disease (aGvHD) in adult and pediatric patients after allogeneic hematopoietic stem cell transplant (HSCT) (Press release, Jazz Pharmaceuticals, FEB 23, 2018, View Source;p=RssLanding&cat=news&id=2334320 [SID1234524137]). The defibrotide clinical trial will be conducted across approximately 60 medical centers in the United States (U.S.), Canada and European Union.

"Potential complications of hematopoietic stem cell transplant such as acute Graft-versus-Host Disease can be life threatening and even fatal," said Karen Smith, M.D., Ph.D., executive vice president, research and development and chief medical officer at Jazz Pharmaceuticals. "Despite the use of current immunoprophylaxis strategies, Graft-versus-Host Disease remains a leading cause of non-relapse mortality after allogeneic stem cell transplant. Jazz is committed to advancing our understanding of how defibrotide may address this unmet need."

The Phase 2 clinical trial is a prospective, randomized, open-label study of the efficacy and safety of defibrotide added to standard of care immunoprophylaxis for the prevention of aGvHD, compared to the standard of care alone. Jazz expects to enroll approximately 150 adult and pediatric patients who have undergone allogeneic HSCT from an unrelated donor. The primary endpoint is cumulative incidence of Grade B-D aGvHD by day +100 post-allogeneic HSCT. Additional information about the trial, including eligibility criteria and a list of clinical trial sites can be found at: View Source (ClinicalTrials.gov Identifier: NCT03339297).

This Phase 2 trial complements the company’s ongoing Phase 3 clinical trial evaluating defibrotide for prevention of hepatic veno-occlusive disease (VOD) in high-risk adult and pediatric patients undergoing hematopoietic stem cell transplant.

About GvHD
Graft-versus-Host-Disease (GvHD) is a life-threatening complication of HSCT, a potentially curative option for several malignant and non-malignant disorders, and occurs when immune cells from a non-identical donor (graft) recognize the transplant recipient (host) as foreign. GvHD is the most frequent cause of morbidity and non-relapse mortality following allogeneic HSCT.1 One in five patients receiving a transplant from an unrelated donor dies from GvHD. Approximately 24,000 allogeneic patients in the United States and Europe are at risk for acute GvHD (aGvHD), which usually occurs within the first 100 days following HSCT and typically involves damage to the skin, gastrointestinal tract and/or liver.1,2,3,4 The International Bone Marrow Transplant Registry (IBMTR) Severity Index grades aGvHD as follows: Grade A includes patients with stage 1 skin aGvHD only; B includes those with stage 2 skin and no visceral aGvHD or stage 0-2 skin with stage 1 or 2 visceral aGvHD; C includes patients with stage 3 skin, liver and/or gut aGvHD; D includes those with stage 4 skin, liver and/or gut aGvHD.5

About Defitelio (defibrotide sodium)
In the U.S., Defitelio (defibrotide sodium) injection 80mg/mL received U.S. FDA marketing approval on March 30, 2016 for the treatment of adult and pediatric patients with hepatic veno-occlusive disease (VOD), also known as sinusoidal obstruction syndrome (SOS), with renal or pulmonary dysfunction following hematopoietic stem-cell transplantation (HSCT) and is the first and only FDA-approved therapy for patients with this rare, potentially fatal complication. Defitelio is not approved for the treatment of prevention of GvHD or prevention of VOD.

Defitelio is contraindicated in patients currently taking anticoagulants or fibrinolytics and in patients who are allergic to Defitelio or any of its ingredients. Defitelio may increase the risk of bleeding and should be withheld or stopped if significant bleeding occurs. Patients should be monitored for allergic reactions, especially if there is a history of previous exposure to Defitelio. The most common side effects of Defitelio are decreased blood pressure, diarrhea, vomiting, nausea and nose bleeds.

Please see full Prescribing Information for Defitelio.

In Europe, defibrotide is marketed under the name Defitelio▼(defibrotide). In October 2013, the European Commission granted marketing authorization to Defitelio under exceptional circumstances for the treatment of severe VOD in patients undergoing HSCT therapy. It is the first and only approved treatment in Europe for severe VOD. In Europe, Defitelio is indicated in patients over one month of age. It is not indicated in patients with hypersensitivity to defibrotide or any of its excipients or with concomitant use of thrombolytic therapy.

▼This medicinal product is subject to additional monitoring. This will allow quick identification of new safety information. Healthcare professionals are asked to report any suspected adverse reactions via the national reporting system found under section 4.8 of the SmPC. (View Source)

About VOD
HSCT is an aggressive, potentially curative procedure to treat patients with malignant and non-cancerous hematologic disorders such as leukemia, lymphoma and aplastic anemia, and congenital immunodeficiency and autoimmune disorders.6 VOD is a rare complication of HSCT that occurs in approximately 9-14% of HSCT patients.7,8 Hepatic VOD, also known as SOS, is an early and life-threatening complication affecting the sinusoidal endothelial cells of the liver, which can typically occur within the first 21 days following HSCT.8,9 Hepatic VOD progresses to become life-threatening in approximately 30-50% of cases.9 VOD with multi-organ dysfunction (MOD), when left untreated, can be associated with an overall mortality (death) rate of 84%.7 MOD is characterized by the presence of renal or pulmonary dysfunction.10,11 VOD is often characterized by sudden weight gain, hepatomegaly (abnormally enlarged liver), and elevated bilirubin.10,11

Bellicum Announces Update on Clinical Hold of U.S. BPX-501 Studies

On February 23, 2018 Bellicum Pharmaceuticals, Inc. (NASDAQ:BLCM), a leader in developing novel, controllable cellular immunotherapies for cancers and orphan inherited blood disorders, reported that it has received notification from the U.S. Food and Drug Administration (FDA) outlining the criteria required for lifting the clinical hold on U.S. studies of BPX-501 (Press release, Bellicum Pharmaceuticals, FEB 23, 2018, View Source [SID1234524133]). To address the FDA requirements, the Company plans to implement revisions to the U.S. study protocols, including the addition of more comprehensive monitoring and management of neurotoxicity. In addition, the Company will revise the Investigator Brochure and Informed Consent Documents to inform healthcare providers, patients and caregivers of the changes. The Company expects to provide a full response to the FDA within a few weeks.

The clinical hold does not affect the Company’s BP-004 registration trial in Europe.

About BPX-501
BPX-501 is an adjunct T cell therapy administered after allogeneic hematopoietic stem cell transplant (HSCT) to improve outcomes in patients who lack a matched donor. It is comprised of genetically modified donor T cells incorporating Bellicum’s CaspaCIDe safety switch. BPX-501 is designed to provide a safety net to eliminate alloreactive BPX-501 T cells (via administration of activator agent rimiducid) should uncontrollable GvHD occur. This enables physicians to more safely perform stem cell transplants by administering BPX-501 engineered T cells to speed immune reconstitution, provide control over viral infections and enhance Graft-versus-leukemic effect without unacceptable GvHD risk.

Lynparza receives positive EU CHMP opinion in platinum-sensitive relapsed ovarian cancer

On February 23, 2018 AstraZeneca and Merck & Co., Inc., Kenilworth, NJ, US (known as MSD outside the US and Canada) reported that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency has adopted a positive opinion, recommending a marketing authorisation of Lynparza (olaparib) tablets (300mg twice daily) for use as a maintenance therapy for patients with platinum-sensitive relapsed high grade, epithelial ovarian, fallopian tube, or primary peritoneal cancer who are in complete response or partial response to platinum-based chemotherapy (Press release, AstraZeneca, FEB 23, 2018, View Source [SID1234524132]). Lynparza is recommended for treatment in this setting regardless of patients’ BRCA mutation status.

Sean Bohen, Executive Vice President, Global Medicines Development and Chief Medical Officer at AstraZeneca, said: "The data show that Lynparza provides long-term disease control, delaying the need for further chemotherapy for this broader group of women with platinum-sensitive relapsed ovarian cancer, irrespective of their BRCA status. It also offers a well-characterised safety and tolerability profile, which is critical to help enable patients to stay on treatment."

Roy Baynes, Senior Vice President and Head of Global Clinical Development, Chief Medical Officer, MSD Research Laboratories, said: "We welcome this positive opinion based upon data which indicate the potential impact for Lynparza as maintenance therapy for women with platinum-sensitive relapsed ovarian cancer. We look forward to our continued work with AstraZeneca to bring Lynparza to patients in the EU."

The CHMP recommendation is based on two randomised trials, SOLO-2 and Study 19, which showed Lynparza reduced the risk of disease progression or death for platinum-sensitive relapsed patients compared to placebo.

The most frequently observed adverse reactions across clinical trials in patients receiving Lynparza monotherapy (≥ 10%) were nausea, vomiting, diarrhoea, dyspepsia, fatigue, headache, dysgeusia, decreased appetite, dizziness and anaemia.

Lynparza, the first poly ADP-ribose polymerase (PARP) inhibitor approved, was initially licensed as a capsule formulation. The new tablet formulation will reduce dosing from 8 capsules twice daily to 2 tablets twice daily.

Lynparza is available in nearly 60 countries and has treated more than 20,000 patients globally. It has the broadest clinical development programme of any PARP inhibitor, and AstraZeneca and MSD are working together to bring Lynparza to more patients across multiple cancers. In January 2018, Lynparza was approved by the US FDA for use in metastatic breast cancer, becoming the first PARP inhibitor licensed beyond ovarian cancer.

NOTES TO EDITORS
About Ovarian Cancer in Europe

Among women in Europe, ovarian cancer is the fifth most common cancer and the sixth leading cause of cancer death. The five-year survival rate for ovarian cancer in Europe is 38%. In 2012, there were nearly 65,000 new cases diagnosed and around 42,700 deaths. As there is no cure for relapsed ovarian cancer, the primary aim of treatment is to slow progression of the disease for as long as possible and improve or maintain the patient’s quality of life.

About SOLO-2

SOLO-2 was a Phase III, randomised, double-blinded, multicentre trial designed to determine the efficacy of Lynparza tablets compared to placebo as maintenance monotherapy in patients with platinum-sensitive relapsed or recurrent germline BRCA-mutated ovarian, fallopian tube and primary peritoneal cancer. The trial, conducted in collaboration with the European Network for Gynaecological Oncological Trial Groups (ENGOT) and Groupe d’Investigateurs National pour l’Etude des Cancers de l’Ovaire et du sein (GINECO), randomised 295 patients with documented germline BRCA1 or BRCA2 mutations who had received at least two prior lines of platinum-based chemotherapy and were in complete or partial response. Eligible patients were randomised to receive 300mg Lynparza tablets twice daily or placebo tablets twice daily.

About Study 19

Study 19 was a Phase II, randomised, double-blinded, placebo-controlled, multicentre trial, which evaluated the efficacy and safety of Lynparza capsules compared with placebo in relapsed, high-grade serous ovarian cancer patients. The trial randomised 265 patients regardless of BRCA mutation status and who had completed at least two courses of platinum-based chemotherapy and their most recent treatment regimen. Eligible patients were randomised to receive Lynparza maintenance monotherapy at a dose of 400mg per day or matching placebo.

About Lynparza (olaparib)

Lynparza is a first-in-class poly ADP-ribose polymerase (PARP) inhibitor and the first targeted treatment to potentially exploit tumour DNA damage response (DDR)-pathway deficiencies to preferentially kill cancer cells. Specifically, in vitro studies have shown that Lynparza-induced cytotoxicity may involve inhibition of PARP enzymatic activity and increased formation of PARP-DNA complexes, resulting in DNA damage and cancer cell death.

Lynparza is being investigated in a range of DDR-deficient tumour types and is the foundation of AstraZeneca’s industry-leading portfolio of compounds targeting DDR mechanisms in cancer cells.

About the AstraZeneca and MSD Strategic Oncology Collaboration

In July 2017, AstraZeneca and Merck & Co., Inc., Kenilworth, NJ, US, known as MSD outside the United States and Canada, announced a global strategic oncology collaboration to co-develop and co-commercialise Lynparza, the world’s first PARP inhibitor, and potential new medicine selumetinib, a MEK inhibitor, for multiple cancer types. The collaboration is based on increasing evidence that PARP and MEK inhibitors can be combined with PD-L1/PD-1 inhibitors for a range of tumour types. Working together, the companies will develop Lynparza and selumetinib in combination with other potential new medicines and as a monotherapy. Independently, the companies will develop Lynparza and selumetinib in combination with their respective PD-L1 and PD-1 medicines.

About AstraZeneca in Oncology
AstraZeneca has a deep-rooted heritage in Oncology and offers a quickly-growing portfolio of new medicines that has the potential to transform patients’ lives and the Company’s future. With at least six new medicines to be launched between 2014 and 2020, and a broad pipeline of small molecules and biologics in development, we are committed to advance New Oncology as one of AstraZeneca’s five Growth Platforms focused on lung, ovarian, breast and blood cancers. In addition to our core capabilities, we actively pursue innovative partnerships and investments that accelerate the delivery of our strategy as illustrated by our investment in Acerta Pharma in haematology.

By harnessing the power of four scientific platforms – Immuno-Oncology, Tumour Drivers and Resistance, DNA Damage Response and Antibody-Drug Conjugates – and by championing the development of personalised combinations, AstraZeneca has the vision to redefine cancer treatment and one day eliminate cancer as a cause of death.

Amgen Receives Positive Opinion Expanding Use Of XGEVA® (denosumab) To Cover Prevention Of Skeletal-Related Events In Patients With Multiple Myeloma In Europe

On February 23, 2018 Amgen (NASDAQ:AMGN) reported that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has adopted a positive opinion to expand the current indication for XGEVA (denosumab) to cover skeletal-related events in patients with multiple myeloma (Press release, Amgen, FEB 23, 2018, View Source;p=RssLanding&cat=news&id=2334313 [SID1234524131]). If approved, XGEVA will be indicated for the prevention of skeletal-related events in adults with advanced malignancies involving bone. The application included new data from the Phase 3 ‘482 study, the largest international multiple myeloma trial for the prevention of skeletal-related events ever conducted.

In the ‘482 study, XGEVA successfully met the primary endpoint, demonstrating non-inferiority 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). The median time to first on-study skeletal-related event was 22.83 months for XGEVA and 23.98 months for zoledronic acid. The safety profile was consistent with known adverse events of XGEVA.

"More than 90 percent of patients with multiple myeloma develop bone lesions over the course of the disease. These can result in fractures and other bone complications," said David M. Reese, M.D., senior vice president of Translational Sciences and Oncology at Amgen. "The positive opinion from the CHMP to expand XGEVA’s indication to cover skeletal-related events in patients with multiple myeloma is an important step forward in Amgen’s commitment to improving care for multiple myeloma patients at risk for developing bone complications."

Bone complications, also known as skeletal-related events, are defined as radiation to bone, pathologic fracture, surgery to bone and spinal cord compression.1

XGEVA is the first fully human monoclonal antibody that binds to and neutralizes RANK ligand (RANKL) – a protein essential for the formation, function and survival of osteoclasts, cells which break down bone – thereby inhibiting osteoclast-mediated bone destruction. On Jan. 5, 2018, the U.S. Food and Drug Administration (FDA) approved the supplemental Biologics License Application (sBLA) for XGEVA to expand the currently approved indication for the prevention of skeletal-related events in patients with bone metastases from solid tumors to include patients with multiple myeloma. Additional regulatory applications for XGEVA for the prevention of skeletal-related events in patients with multiple myeloma are underway and have been submitted to health authorities worldwide.

Following the CHMP positive opinion, the centralized European marketing authorization of XGEVA will be expanded to cover the multiple myeloma patient population. Norway, Iceland and Liechtenstein, as members of the European Economic Area (EEA), will take corresponding decisions on the basis of the decision of the European Commission.

About ‘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 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 at baseline) and subcutaneous placebo every four weeks, plus investigators’ choice first-line antimyeloma therapy. Skeletal surveys using conventional radiography were obtained every 12 to 24 weeks per protocol. 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). The safety and tolerability of XGEVA were also compared with zoledronic acid. An open-label extension of the study is ongoing.

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).1,4 Each year an estimated 114,000 new cases of multiple myeloma are diagnosed worldwide, resulting in more than 80,000 deaths per year.1

More than 90 percent of patients develop osteolytic lesions during the course of the disease.1 Preventing bone complications is a critical aspect of caring for patients with multiple myeloma, because these events can result in significant morbidity.5 Current treatment options to prevent bone complications are limited to bisphosphonates, including zoledronic acid, which are cleared through the kidneys.6 Approximately 60 percent of all multiple myeloma patients have or will develop renal impairment over the course of the disease.7

About XGEVA (denosumab)
XGEVA targets the RANKL pathway to prevent the formation, function and survival of osteoclasts, which break down bone. XGEVA is indicated for the prevention of skeletal-related events in patients with multiple myeloma and in patients with bone metastases from solid tumors. 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. Additionally, XGEVA is indicated in the U.S. for the treatment of hypercalcemia of malignancy refractory to bisphosphonate therapy.

EU Important Safety Information

∇ This medicinal product is subject to additional monitoring. This will allow quick identification of new safety information. Healthcare professionals are asked to report any suspected adverse reactions.

Calcium and Vitamin D supplementation
Supplementation with calcium and vitamin D is required in all patients unless hypercalcaemia is present.

Hypocalcaemia
Pre-existing hypocalcaemia must be corrected prior to initiating therapy with XGEVA. Hypocalcaemia can occur at any time during therapy with XGEVA. Monitoring of calcium levels should be conducted (i) prior to the initial dose of XGEVA, (ii) within two weeks after the initial dose, (iii) if suspected symptoms of hypocalcaemia occur. Additional monitoring of calcium level should be considered during therapy in patients with risk factors for hypocalcaemia, or if otherwise indicated based on the clinical condition of the patient.

Patients should be encouraged to report symptoms indicative of hypocalcaemia. If hypocalcaemia occurs while receiving XGEVA, additional calcium supplementation and additional monitoring may be necessary.

In the post marketing setting, severe symptomatic hypocalcaemia (including fatal cases) has been reported, with most cases occurring in the first weeks of initiating therapy, but can occur later.

Renal impairment
Patients with severe renal impairment (creatinine clearance < 30 ml/min) or receiving dialysis are at greater risk of developing hypocalcaemia. The risk of developing hypocalcaemia and accompanying elevations in parathyroid hormone increases with increasing degree of renal impairment. Regular monitoring of calcium levels is especially important in these patients.

Osteonecrosis of the jaw (ONJ)
ONJ has been reported commonly in patients receiving XGEVA.

The start of treatment/new treatment course should be delayed in patients with unhealed open soft tissue lesions in the mouth. A dental examination with preventive dentistry and an individual benefit-risk assessment is recommended prior to treatment with XGEVA.

The following risk factors should be considered when evaluating a patient’s risk of developing ONJ:

potency of the medicinal product that inhibits bone resorption (higher risk for highly potent compounds), route of administration (higher risk for parenteral administration) and cumulative dose of bone resorption therapy.
cancer, co-morbid conditions (e.g. anaemia, coagulopathies, infection), smoking.
concomitant therapies: corticosteroids, chemotherapy, angiogenesis inhibitors, radiotherapy to head and neck.
poor oral hygiene, periodontal disease, poorly fitting dentures, pre-existing dental disease, invasive dental procedures (e.g. tooth extractions).
All patients should be encouraged to maintain good oral hygiene, receive routine dental check-ups, and immediately report any oral symptoms such as dental mobility, pain or swelling, or non-healing of sores or discharge during treatment with XGEVA. While on treatment, invasive dental procedures should be performed only after careful consideration and be avoided in close proximity to XGEVA administration.

The management plan of the patients who develop ONJ should be set up in close collaboration between the treating physician and a dentist or oral surgeon with expertise in ONJ. Temporary interruption of XGEVA treatment should be considered until the condition resolves and contributing risk factors are mitigated where possible.

Osteonecrosis of the external auditory canal
Osteonecrosis of the external auditory canal has been reported with denosumab. Possible risk factors for osteonecrosis of the external auditory canal include steroid use and chemotherapy and/or local risk factors such as infection or trauma. The possibility of osteonecrosis of the external auditory canal should be considered in patients receiving denosumab who present with ear symptoms including chronic ear infections.

Atypical fractures of the femur
Atypical femoral fractures have been reported in patients receiving XGEVA. Atypical femoral fractures may occur with little or no trauma in the subtrochanteric and diaphyseal regions of the femur. Specific radiographic findings characterise these events. Atypical femoral fractures have also been reported in patients with certain comorbid conditions (e.g. vitamin D deficiency, rheumatoid arthritis, hypophosphatasia) and with use of certain pharmaceutical agents (e.g. bisphosphonates, glucocorticoids, proton pump inhibitors). These events have also occurred without antiresorptive therapy. Similar fractures reported in association with bisphosphonates are often bilateral; therefore the contralateral femur should be examined in denosumab-treated patients who have sustained a femoral shaft fracture. Discontinuation of XGEVA therapy in patients suspected to have an atypical femur fracture should be considered pending evaluation of the patient based on an individual benefit risk assessment. During XGEVA treatment, patients should be advised to report new or unusual thigh, hip, or groin pain. Patients presenting with such symptoms should be evaluated for an incomplete femoral fracture.

Patients with growing skeletons
XGEVA is not recommended in patients with growing skeletons. Clinically significant hypercalcaemia has been reported in XGEVA-treated patients with growing skeletons weeks to months following treatment discontinuation.

Others
Patients being treated with XGEVA should not be treated concomitantly with other denosumab containing medicinal products (for osteoporosis indications).

Patients being treated with XGEVA should not be treated concomitantly with bisphosphonates.

Malignancy in Giant Cell Tumour of Bone or progression to metastatic disease is an infrequent event and a known risk in patients with Giant Cell Tumour of Bone. Patients should be monitored for radiological signs of malignancy, new radiolucency or osteolysis. Available clinical data does not suggest an increased risk of malignancy in GCTB patients treated with XGEVA.

Warnings for excipients
XGEVA contains sorbitol. Patients with rare hereditary problems of fructose intolerance should not use XGEVA.

This medicinal product contains less than 1 mmol sodium (23 mg) per 120 mg, i.e. essentially ‘sodium-free’.

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.

Multiple Vertebral Fractures (MVF) Following Treatment Discontinuation
Multiple vertebral fractures (MVF) have been reported following discontinuation of treatment with denosumab. Patients at higher risk for MVF include those with risk factors for or a history of osteoporosis or prior fractures. When XGEVA treatment is discontinued, evaluate the individual patient’s risk for vertebral fractures.

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.

For multiple myeloma patients receiving XGEVA, the most common adverse reactions were diarrhea, nausea, anemia, back pain, thrombocytopenia, peripheral edema, hypocalcemia, upper respiratory tract infection, rash, and headache. The most common serious adverse reaction was pneumonia. The most common adverse reaction resulting in discontinuation of XGEVA was osteonecrosis of the jaw.

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.
