The Phase III study is an open-label, multicenter, 1:1 randomized clinical trial where patients with stage IIIb/IV NSCLC will receive either avelumab or docetaxel, regardless of PD-L1 status. Approximately 650 patients will participate across 290 sites in more than 30 countries in North America, South America, Asia, Africa and Europe. In North America, clinical trials on behalf of Merck KGaA, Darmstadt, Germany, will be conducted by EMD Serono, the company’s US and Canadian biopharmaceutical businesses. The study is part of the JAVELIN clinical trial program for avelumab.

The primary endpoint of the study is overall survival (OS) in patients with programmed death-ligand 1 positive (PD-L1+) stage IIIb/IV NSCLC who have experienced disease progression after receiving a prior platinum-containing doublet therapy. Secondary endpoints will be assessed across the entire study population regardless of PD-L1 status and include OS; overall response rate (ORR); progression-free survival (PFS); and patient-reported outcomes.

"New and innovative treatment strategies are urgently needed to improve overall survival for patients with NSCLC, and we are investigating avelumab as a potential treatment option for patients with this very difficult-to-treat disease," said Dr. Luciano Rossetti, Global Head of R&D of the biopharmaceutical business of Merck KGaA, Darmstadt, Germany. "The treatment of the first patient in the Phase III trial is an important milestone for our immuno-oncology alliance."

"This trial marks the first of several registration studies we are planning to initiate this year together, and underscores our commitment to accelerating the development of medications for patients with cancer," said Dr. Mace Rothenberg, Senior Vice President of Clinical Development and Medical Affairs and Chief Medical Officer for Pfizer Oncology. "Through this alliance, we will have the opportunity to combine the promising anti-PD-L1 antibody, avelumab, with our combined portfolios of approved and investigational oncology therapies, which may provide an exciting opportunity to potentially broaden the use of immunotherapy for patients with cancer."

The JAVELIN clinical trial program also includes an international Phase II trial to investigate avelumab in patients with metastatic Merkel cell carcinoma; an international Phase I trial to investigate avelumab in patients with metastatic or locally advanced solid tumors, and a Phase I trial to investigate avelumab in Japanese patients with metastatic or locally advanced solid tumors with an expansion part in Asian patients with gastric cancer. The Phase I program for avelumab includes more than 840 patients treated across multiple tumor types, including NSCLC, breast cancer, gastric cancer, ovarian cancer, bladder cancer, melanoma and mesothelioma.

*Avelumab is the proposed International Nonproprietary Name (INN) for the anti-PD-L1 monoclonal antibody (MSB0010718C)

About Non-Small Cell Lung Cancer

Globally, lung cancer is the most common cause of cancer-related deaths in men and the second most common in women, responsible for almost twice as many deaths as both breast and prostate cancer combined1. NSCLC is the most common type of lung cancer, accounting for 85 to 90 percent of all lung cancers2. Locally advanced and metastatic disease account for approximately 35 to 40 percent3 and 70 percent4 of patients, respectively with NSCLC.

Avelumab

Avelumab (also known as MSB0010718C) is an investigational fully human anti-PD-L1 IgG1 monoclonal antibody. By inhibiting PD-L1 interactions, avelumab is thought to enable the activation of T-cells and the adaptive immune system. By retaining a native Fc-region, avelumab is thought to engage the innate immune system and induce antibody-dependent cell-mediated cytotoxicity (ADCC). In November, 2014, Merck KGaA, Darmstadt, Germany, and Pfizer announced a strategic alliance to co-develop and co-commercialize avelumab.

JAVELIN Clinical Trial Program for Avelumab

JAVELIN is an expansive international clinical trial program exploring the use of PD-L1 inhibition with avelumab to treat multiple types of cancer. The JAVELIN clinical trial program includes a Phase III study designed to assess the efficacy and safety of avelumab compared with docetaxel in patients with stage IIIb/IV NSCLC who have experienced disease progression after receiving a prior platinum-containing doublet therapy; an international Phase II open-label multicenter trial to investigate the clinical activity and safety of avelumab in patients with metastatic Merkel cell carcinoma; an international Phase I open-label, multiple ascending dose trial to investigate the safety, tolerability, pharmacokinetics, biological and clinical activity in patients with metastatic or locally advanced solid tumors; and a Phase I trial to investigate the tolerability, safety, pharmacokinetics, biological, and clinical activity of avelumab in Japanese patients with metastatic or locally advanced solid tumors with an expansion part in Asian patients with gastric cancer.

Alliance between Merck KGaA, Darmstadt, Germany, and Pfizer Inc, New York, US

Immuno-oncology is a top priority for Merck KGaA, Darmstadt, Germany, and Pfizer Inc. The global strategic alliance between Merck KGaA, Darmstadt, Germany, and Pfizer Inc, New York, US, enables the companies to benefit from each other’s strengths and capabilities and further explore the therapeutic potential of avelumab, an investigational anti-PD-L1 antibody initially discovered and developed by Merck KGaA, Darmstadt, Germany. The immuno-oncology alliance will jointly develop and commercialize avelumab and advance Pfizer’s PD-1 antibody. The companies will collaborate on up to 20 high priority immuno-oncology clinical development programs, including combination trials, many of which are expected to commence in 2015.

TetraLogic and Merck to Collaborate on the Evaluation of Birinapant in Combination with KEYTRUDA® (pembrolizumab) in Solid Tumors

On April 20, 2015 TetraLogic Pharmaceuticals and Merck reported they have entered into an oncology clinical study collaboration (Press release, Merck & Co, APR 20, 2015, http://www.mercknewsroom.com/news-release/oncology-newsroom/tetralogic-and-merck-collaborate-evaluation-birinapant-combination-ke [SID:1234503073]). The companies will collaborate on a Phase 1 study to evaluate the safety and efficacy of birinapant, TetraLogic’s SMAC-mimetic, in combination with KEYTRUDA (pembrolizumab), Merck’s anti-PD-1 therapy, in patients with relapsed or refractory solid tumors. The study is expected to begin in late 2015.

KEYTRUDA and birinapant target different elements of cancer’s block against the immune system. TetraLogic’s birinapant (TL32711) is a potent, bivalent SMAC-mimetic that binds with differential affinity to multiple members of the IAP family in order to re-establish the immune system’s ability to kill abnormal cells via an extracellular TNF signal. Merck’s KEYTRUDA is a humanized monoclonal antibody that blocks the interaction between PD-1 (programmed death receptor-1) and its ligands, PD-L1 and PD-L2. The proposed collaboration is based on preclinical data that suggest SMAC-mimetics have the potential to enhance existing immuno-oncology agents, such as KEYTRUDA.

"We are very excited to work with Merck to evaluate birinapant in combination with KEYTRUDA," said J. Kevin Buchi, President and Chief Executive Officer of TetraLogic. "Both molecules are designed to help the body’s immune system better attack cancer cells, and we think the combination could be very promising."

"We are establishing a broad base of clinical evidence with our anti-PD-1 therapy, KEYTRUDA, as monotherapy across different types of cancer," said Dr. Eric Rubin, vice president and therapeutic area head, oncology early-stage development, Merck Research Laboratories. "We believe there is great potential to advance our clinical program and the field of immuno-oncology research through strategic collaborations and synergistic combinations, such as with KEYTRUDA and birinapant."

Under the terms of the agreement, TetraLogic and Merck, through subsidiaries, will collaborate on an initial Phase 1 dose-escalation study of birinapant in combination with KEYTRUDA in patients with relapsed or refractory solid tumors. TetraLogic will sponsor and fund the study and Merck will provide KEYTRUDA. The companies have formed a Joint Development Committee to collaboratively oversee the conduct of the study. Results from the study will be used to determine the path for further clinical development of the combination.

About Birinapant

Cancer and chronically infected cells are able to evade a critical mechanism by which the immune system normally kills abnormal or genetically modified cells. They do this by upregulating the Inhibitors of Apoptosis (IAP) Proteins. Birinapant (TL32711) is a potent, bivalent SMAC-mimetic that binds with differential affinity to multiple members of the IAP family in order to re-establish the immune system’s ability to kill abnormal cells via an extracellular TNF signal. Birinapant has been studied in over 350 patients, and is currently in Phase 1 and Phase 2 trials for Myelodysplastic Syndrome (MDS), Ovarian Cancer and Hepatitis B.

About KEYTRUDA (pembrolizumab)

KEYTRUDA (pembrolizumab) is a humanized monoclonal antibody that blocks the interaction between PD-1 and its ligands, PD-L1 and PD-L2. By binding to the PD-1 receptor and blocking the interaction with the receptor ligands, KEYTRUDA releases the PD-1 pathway-mediated inhibition of the immune response, including the anti-tumor immune response.

KEYTRUDA is indicated in the United States at a dose of 2 mg/kg administered as an intravenous infusion over 30 minutes every three weeks for the treatment of patients with unresectable or metastatic melanoma and disease progression following ipilimumab and, if BRAF V600 mutation positive, a BRAF inhibitor. This indication is approved under accelerated approval based on tumor response rate and durability of response. An improvement in survival or disease-related symptoms has not yet been established. Continued approval for this indication may be contingent upon verification and description of clinical benefit in the confirmatory trials.

Merck is advancing a broad and fast-growing clinical development program for KEYTRUDA with more than 85 clinical trials – across more than 30 tumor types and over 14,000 patients – both as a monotherapy and in combination with other therapies.

Selected Important Safety Information for KEYTRUDA

Pneumonitis occurred in 12 (2.9%) of 411 patients with advanced melanoma receiving KEYTRUDA (the approved indication in the United States), including Grade 2 or 3 cases in 8 (1.9%) and 1 (0.2%) patients, respectively. 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 pneumonitis.

Colitis (including microscopic colitis) occurred in 4 (1%) of 411 patients, including Grade 2 or 3 cases in 1 (0.2%) and 2 (0.5%) patients respectively, receiving KEYTRUDA. 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.

Hepatitis (including autoimmune hepatitis) occurred in 2 (0.5%) of 411 patients, including a Grade 4 case in 1 (0.2%) patient, receiving KEYTRUDA. 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.

Hypophysitis occurred in 2 (0.5%) of 411 patients, including a Grade 2 case in 1 and a Grade 4 case in 1 (0.2% each) patient, receiving KEYTRUDA. Monitor for signs and symptoms of hypophysitis. Administer corticosteroids for Grade 2 or greater hypophysitis. Withhold KEYTRUDA for Grade 2; withhold or discontinue for Grade 3; and permanently discontinue KEYTRUDA for Grade 4 hypophysitis.

Nephritis occurred in 3 (0.7%) patients receiving KEYTRUDA, consisting of one case of Grade 2 autoimmune nephritis (0.2%) and two cases of interstitial nephritis with renal failure (0.5%), one Grade 3 and one Grade 4. 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.

Hyperthyroidism occurred in 5 (1.2%) of 411 patients, including Grade 2 or 3 cases in 2 (0.5%) and 1 (0.2%) patients respectively, receiving KEYTRUDA. Hypothyroidism occurred in 34 (8.3%) of 411 patients, including a Grade 3 case in 1 (0.2%) patient, receiving KEYTRUDA. Thyroid disorders can occur at any time during treatment. 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 corticosteroids for Grade 3 or greater hyperthyroidism. Withhold KEYTRUDA for Grade 3; permanently discontinue KEYTRUDA for Grade 4 hyperthyroidism. Isolated hypothyroidism may be managed with replacement therapy without treatment interruption and without corticosteroids.

Other clinically important immune-mediated adverse reactions can occur. The following clinically significant, immune-mediated adverse reactions occurred in less than 1% of patients treated with KEYTRUDA: exfoliative dermatitis, uveitis, arthritis, myositis, pancreatitis, hemolytic anemia, partial seizures arising in a patient with inflammatory foci in brain parenchyma, adrenal insufficiency, myasthenic syndrome, optic neuritis, and rhabdomyolysis.

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 of the adverse reaction to Grade 1 or less, initiate corticosteroid taper and continue to taper over at least 1 month. Restart KEYTRUDA if the adverse reaction remains at Grade 1 or less. Permanently discontinue KEYTRUDA for any severe or Grade 3 immune-mediated adverse reaction that recurs and for any life-threatening immune-mediated adverse reaction.

Based on its mechanism of action, KEYTRUDA may 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.

For the treatment of advanced melanoma, KEYTRUDA was discontinued for adverse reactions in 6% of 89 patients who received the recommended dose of 2 mg/kg and 9% of 411 patients across all doses studied. Serious adverse reactions occurred in 36% of patients receiving KEYTRUDA. The most frequent serious adverse drug reactions reported in 2% or more of patients were renal failure, dyspnea, pneumonia, and cellulitis.

The most common adverse reactions (reported in ≥20% of patients) were fatigue (47%), cough (30%), nausea (30%), pruritus (30%), rash (29%), decreased appetite (26%), constipation (21%), arthralgia (20%), and diarrhea (20%).

The recommended dose of KEYTRUDA is 2 mg/kg administered as an intravenous infusion over 30 minutes every three weeks until disease progression or unacceptable toxicity. No formal pharmacokinetic drug interaction studies have been conducted with KEYTRUDA. 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. Safety and effectiveness of KEYTRUDA have not been established in pediatric patients.

Panther Biotechnology Announces New Drug Candidate to Selectively Kill Leukemia Stem Cells

On April 17, 2015 Panther Biotechnology, Inc. ( OTC PINK : PBYA ), a biotechnology company specializing in the development of enhanced therapeutics for the treatment of neoplastic disorders reported that it has entered into an exclusive global license agreement with the University of Rochester (Press release, Panther Biotechnology, APR 17, 2015, View Source [SID1234517371]).

Under the terms of the agreement, Panther has licensed from the University of Rochester, the rights to develop and commercialize a first in class new chemical entity with demonstrated powerful anti-leukemia activity. The licensed compound, called TDZD-8, is a small molecule engineered to kill leukemic stem cells. TDZD-8 has demonstrated broad and selective in vitro activity against many different types of leukemia. In addition, TDZD-8 has no significant toxicity in normal hematopoietic stem cells. The license is based on the pending US patent 12/374,002, pending EU patent 07810619.2, issued Australia patent 2007275686, and issued New Zealand patent 574619, all filed under "Thiadiazolidinone Derivatives."

"Leukemia is thought to arise from malignant stem cells that are relatively resistant to current chemotherapy and likely contribute to disease relapse and progression. Therefore, the identification of drugs that can efficiently eradicate leukemia stem cells is an important priority," stated Craig T. Jordan, PhD., the University of Rochester Medical Center leading inventor. "We believe that TDZD-8 uses a unique and previously unknown mechanism to rapidly target leukemia cells, including malignant stem and progenitor populations."

Studies of TDZD-8 were performed to determine the effects on different types of leukemia cells taken from patients (AML, bcCML, CLL and ALL), and on normal blood cells as well. All forms of leukemia cells were strongly inhibited and induced to die by TDZD-8, however, there was minimal effect on normal blood cells. Further, TDZD-8 was submitted for screening against the NCI60 panel and found to be selectively cytotoxic to leukemia cells and cells from related diseases. The compound does not greatly impact tumors derived from non-blood tissues.

TDZD-8 is a kinase inhibitor and induces oxidative stress, causing its striking ability to induce the leukemia cells to die after less than 2 hours of exposure to the drug.

"This license agreement represents an opportunity to augment our chemotherapeutics portfolio with drugs aimed at survival extension and low toxicity with a cutting edge, cancer stem cell targeting drug," stated Evan Levine, Chief Executive Officer of Panther. "As we continue advancing our programs, we look forward to moving TDZD-8 into the clinic to target cancer stem cells and complement our other drugs that target the bulk tumor." Mr. Levine added, "Panther has now established a robust pipeline and is continuing its acquisition strategy with the goal of adding more advanced clinical stage products."

"Even as targeted agents and immunotherapeutic approaches come of age, chemotherapy remains a staple of a large number of effective cancer treatment regimens — and will remain so for a long time. Improving chemotherapy by adding new compounds such as Numonafide and TRF-DOX (transferrin-doxorubicin conjugate) to the clinical toolbox will undoubtedly improve patient outcome," stated Jayesh Mehta MD, Professor of Medicine and Director of Hematopoietic Stem Cell Transplantation at the Northwestern University Feinberg School of Medicine. "With our new collaboration with the University of Rochester, Panther is now looking into the future and we are excited to complement our growing pipeline with TDZD-8, which is a state-of-the-art compound directed at the leukemic stem cell. This type of drug will eventually change the way we treat patients and improve response rates."

CheckMate -057, a Pivotal Phase III Opdivo (nivolumab) Lung Cancer Trial, Stopped Early

On April 17, 2015 Bristol-Myers Squibb reported that an open-label, randomized Phase III study evaluating Opdivo (nivolumab) versus docetaxel in previously treated patients with advanced non-squamous non-small cell lung cancer (NSCLC) was stopped early because an assessment conducted by the independent Data Monitoring Committee (DMC) concluded that the study met its endpoint, demonstrating superior overall survival in patients receiving Opdivo compared to the control arm (Press release, Bristol-Myers Squibb, APR 17, 2015, View Source [SID:1234503038]). The company looks forward to sharing these data with health authorities soon.

"The results of CheckMate -057 mark the second time Opdivo has demonstrated a survival advantage in lung cancer," said Michael Giordano, senior vice president, Head of Development, Oncology, Bristol-Myers Squibb. "Through our Opdivo clinical development program, we seek to bring the potential for long-term survival to a broad range of patients, across lines of therapy and stages of disease."

CheckMate -057 investigators are being informed of the decision to stop the comparative portion of the trial. Bristol-Myers Squibb is working to ensure that eligible patients will be informed of the opportunity to continue or start treatment with Opdivo in an open-label extension as part of the company’s commitment to providing patient access to Opdivo, and characterizing long-term survival. The company will complete a full evaluation of the final CheckMate -057 data and work with investigators on the future presentation and publication of the results.

About CheckMate -057

CheckMate -057 is a Phase III, open-label, randomized study of Opdivo versus docetaxel in previously treated patients with advanced or metastatic non-squamous NSCLC. The trial randomized 582 patients to receive either nivolumab 3 mg/kg intravenously every two weeks or docetaxel 75 mg/m2 intravenously every three weeks. The primary endpoint is overall survival. Secondary endpoints include objective response rate and progression free survival.

About Lung Cancer

Lung cancer is the leading cause of cancer deaths globally, resulting in more than 1.5 million deaths each year according the World Health Organization. NSCLC is one of the most common types of the disease and accounts for approximately 85 percent of cases. Survival rates vary depending on the stage and type of the cancer when it is diagnosed. Globally, the five-year survival rate for Stage I NSCLC is between 47 and 50 percent; for Stage IV NSCLC, the five-year survival rate drops to two percent.

Immuno-Oncology at Bristol-Myers Squibb

Surgery, radiation, cytotoxic or targeted therapies have represented the mainstay of cancer treatment over the last several decades, but long-term survival and a positive quality of life have remained elusive for many patients with advanced disease.

To address this unmet medical need, Bristol-Myers Squibb is leading research in an innovative field of cancer research and treatment known as immuno-oncology, which involves agents whose primary mechanism is to work directly with the body’s immune system to fight cancer. The company is exploring a variety of compounds and immunotherapeutic approaches for patients with different types of cancer, including researching the potential of combining immuno-oncology agents that target different and complementary pathways in the treatment of cancer.

Bristol-Myers Squibb is committed to advancing the science of immuno-oncology, with the goal of changing survival expectations and the way patients live with cancer.

About Opdivo

Opdivo is a programmed death-1 (PD-1) immune checkpoint inhibitor that has received approval from the U.S. Food and Drug Administration as a monotherapy in two cancer indications. On March 5, 2015, Opdivo received FDA approval for the treatment of patients with metastatic squamous non-small cell lung cancer (NSCLC) with progression on or after platinum-based chemotherapy.

In the U.S., Opdivo is also indicated for the treatment of patients with unresectable or metastatic melanoma and disease progression following Yervoy (ipilimumab) and, if BRAF V600 mutation positive, a BRAF inhibitor. This indication is approved under accelerated approval based on tumor response rate and durability of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in the confirmatory trials. Opdivo became the first PD-1 immune checkpoint inhibitor to receive regulatory approval anywhere in the world on July 4, 2014 when Ono Pharmaceutical Co. announced that it received manufacturing and marketing approval in Japan for the treatment of patients with unresectable melanoma. Bristol-Myers Squibb has a broad, global development program to study Opdivo in multiple tumor types consisting of more than 50 trials – as monotherapy or in combination with other therapies – in which more than 7,000 patients have been enrolled worldwide.

Selumetinib granted Orphan Drug Designation by US FDA for treatment of uveal melanoma

On April 17, 2015 AstraZeneca reported that the US Food and Drug Administration has granted Orphan Drug Designation for the MEK inhibitor selumetinib, for the treatment of uveal melanoma (Press release, AstraZeneca, APR 17, 2015, View Source;selumetinib-granted-orphan-drug-designation-by-us-fda [SID:1234503032]).

Uveal melanoma is a rare disease in which cancer cells form in the tissues of the eye. It is the most common primary intraocular malignancy in adults and comprises 5% of all melanomas1,2.

"Uveal melanoma is a rare and devastating disease for which there are currently no effective treatment options once it spreads beyond the tissues of the eye. Selumetinib could potentially become the first effective treatment for these patients. The Orphan Drug Designation is an important regulatory advancement as we further our development plans for selumetinib in uveal melanoma," said Antoine Yver, Head of Oncology, Global Medicines Development at AstraZeneca.

The Orphan Drug Designation programme provides orphan status to drugs and biologics, which are defined as those intended for the safe and effective treatment, diagnosis or prevention of rare diseases or disorders that affect fewer than 200,000 people in the US3.

Selumetinib, originally licensed from Array BioPharma Inc., inhibits the MEK pathway in cancer cells to prevent the tumour from growing. Data from a phase III study evaluating selumetinib in combination with chemotherapy in patients with first-line metastatic uveal melanoma is expected to be available later this year. In addition to uveal melanoma, selumetinib is being investigated in Phase III studies in KRAS mutation positive lung cancer and thyroid cancer and in Phase II in children with neurofibromatosis Type 1.

Initial data from a combination study of selumetinib with other AstraZeneca pipeline molecules including AZD9291 (T790M-directed EGFR inhibitor) and MEDI4736 (anti-PD-L1) in non-small cell lung cancer will be presented at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) annual meeting 2015.
