Bristol-Myers Squibb and Ono Pharmaceutical Company Enter Settlement and License Agreement with Merck to Resolve PD-1 Antibody Patent Litigation

On January 20, 2017 Bristol-Myers Squibb Company (NYSE:BMY) and Ono Pharmaceutical Company, Ltd. reported the companies have signed a global patent license agreement with Merck & Co., Inc. (NYSE: MRK) to settle all patent-infringement litigation related to Merck’s PD-1 antibody Keytruda (pembrolizumab) (Press release, Bristol-Myers Squibb, JAN 20, 2017, View Source [SID1234517479]). The agreement will result in the dismissal with prejudice of all patent litigation between the companies pertaining to Keytruda. Bristol-Myers Squibb and Ono, who discovered and developed the PD-1 antibody Opdivo (nivolumab), had asserted in litigation that Merck’s sale of Keytruda infringed the companies’ patents relating to the use of PD-1 antibodies to treat cancer in the U.S., Europe (United Kingdom, Netherlands, France, Germany, Ireland, Spain and Switzerland), Australia, and Japan.

Under the agreement, the companies have also granted certain rights to each other under their respective patent portfolios pertaining to PD-1. The royalties will be shared between Bristol-Myers Squibb and Ono in a 75/25 percent allocation, respectively.

"Bristol-Myers Squibb and Ono’s agreement with Merck protects our scientific discoveries and validates the strong intellectual property rights we secured as the early innovators in the science of PD-1, a key mechanism in Immuno-Oncology that has proven to have transformational impact in cancer care," says Giovanni Caforio, M.D., chief executive officer, Bristol-Myers Squibb. "Today’s agreement is also a good decision for patients as it supports the continuation of ongoing research and maintains access to anti-PD-1 therapies for cancer patients around the world."

Opdivo is a programmed death-1 (PD-1) immune checkpoint inhibitor that is designed to uniquely harness the body’s own immune system to help restore anti-tumor immune response. By harnessing the body’s own immune system to fight cancer, Opdivo has become an important treatment option across multiple cancers. Opdivo was the first PD-1 immune checkpoint inhibitor to receive regulatory approval anywhere in the world in July 2014, and currently has regulatory approval in 60 countries including the United States, Japan, and in the European Union.

IMPORTANT SAFETY INFORMATION

WARNING: IMMUNE-MEDIATED ADVERSE REACTIONS

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

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

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

Immune-Mediated Pneumonitis

OPDIVO can cause immune-mediated pneumonitis. Fatal cases have been reported. Monitor patients for signs with radiographic imaging and for symptoms of pneumonitis. Administer corticosteroids for Grade 2 or more severe pneumonitis. Permanently discontinue for Grade 3 or 4 and withhold until resolution for Grade 2.

Immune-Mediated Encephalitis

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

Other Immune-Mediated Adverse Reactions

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

Infusion Reactions

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

Complications of Allogeneic HSCT after OPDIVO

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

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

Embryo-Fetal Toxicity

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

Lactation

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

"We hope that the addition of ADI‑PEG 20, which has a different mechanism of action than cytarabine, will result in both safety and added efficacy", said John Bomalaski, M.D., Executive Vice President, Medical Affairs at Polaris Pharmaceuticals, Inc.

About ADI‑PEG 20

ADI‑PEG 20 is a biologic being developed by Polaris Group to treat cancers carrying a major metabolic defect that renders them unable to internally synthesize arginine. Because arginine is essential for protein synthesis and survival of cells, these cancer cells become dependent upon the external supply of arginine to survive and grow. ADI‑PEG 20 is designed to deplete the external supply of arginine, causing arginine-dependent cancer cells to die while leaving the patient’s normal cells unharmed. Multiple cancers have been reported to have a high degree of arginine-dependency and can potentially be treated with ADI‑PEG 20.

The CRT Pioneer Fund and Cancer Research UK’s Manchester Institute nominate cancer drug candidate

On January 20, 2017 The Cancer Research Technology Pioneer Fund LP (CPF) reported that it will further develop a promising class of cancer drugs called RET inhibitors, through a collaboration with the Cancer Research UK Manchester Institute Drug Discovery Unit*, at The University of Manchester (Press release, Cancer Research Technology, 20 20, 2017, View Source [SID1234523171]).

A potential drug candidate identified through the collaboration has entered preclinical studies, the stage necessary to enable an investigational new drug (IND) application. These studies ensure the drug is safe to be given to patients. If the studies are successful the experimental drug will be funded through early clinical trials.

Ian Miscampbell, managing partner of Sixth Element Capital which manages the CPF, said: "We’re delighted to announce this significant project milestone. And the further investment we’ve made will pave the way for a potential new cancer drug to be taken into phase I clinical trials. If the first studies are successful we’ll seek industry partners to further develop and commercialise these drugs."

The RET inhibitor programme was led by scientists at Cancer Research UK’s Manchester Institute. Investment by the CPF in 2014 built on the research of the group and enabled the acceleration of the programme.

The RET gene plays a critical role in the development of medullary thyroid cancer. Up to two percent of non-small cell lung adenocarcinomas – originating in the mucus-secreting cells lining the airways – have RET mutations. The project aims to discover novel compounds targeting the RET gene in a specific population of patients.

Dr Donald Ogilvie, head of drug discovery at the Cancer Research UK Manchester Institute at The University of Manchester, said: "We’re pleased to work with the CRT Pioneer Fund to accelerate progress on the exciting RET inhibitors discovered by Cancer Research UK scientists at our Institute.

"Lung cancer can be difficult to treat successfully. As part of the Cancer Research UK Lung Cancer Centre of Excellence, we’re determined to get new lung cancer treatments to patients. Identifying this candidate drug molecule offers the potential to help boost survival from this disease."

Dr Phil L’Huillier, Cancer Research Technology’s director of business development, said: "It’s fantastic news that CRT’s Pioneer Fund has helped speed up this important research from the lab to potentially benefit patients. It’s essential that we bridge the innovation gap in UK drug discovery, so that patients can quickly get the promising new drugs being developed in Cancer Research UK labs and elsewhere around the world."

The Phase 1b trial is intended to determine the maximum-tolerated dose of brontictuzumab in combination with trifluridine/tipiracil (Lonsurf). The Phase 1b trial is designed to assess safety, preliminary efficacy and immunogenicity, as well as predictive and pharmacodynamics biomarkers. Metastatic colorectal cancer patients who have received at least two prior lines of therapy will be enrolled in the dose-escalation portion of the trial, and once a maximum tolerated dose is identified, additional patients whose tumors test high for the activated form of Notch1 will be enrolled in an expansion cohort.

"Brontictuzumab targets Notch1, a key receptor in the Notch pathway, and preclinical data suggest that elevated Notch1 gene expression appears to be an oncogenic driver in a number of tumor types, including colorectal cancer," said Robert Stagg, Pharm.D., OncoMed’s Senior Vice President, Clinical Research and Development. "In this Phase 1b trial, we expect to determine the safety and optimal therapeutic index of brontictuzumab in combination with chemotherapy, assess preliminary efficacy and explore the correlation of biomarker status and anti-tumor responses."

About Brontictuzumab
Brontictuzumab (anti-Notch1, OMP-52M51) blocks signaling of Notch, an important cancer stem cell pathway implicated in chemoresistance, tumor angiogenesis and stem cell self-renewal, proliferation and differentiation. Notch1 signaling is prevalent in several solid tumor types, including certain breast, esophageal, colorectal, gastric, pancreatic and small cell lung cancers, as well as adenoid cystic carcinoma and cholangiocarcinoma. Single-agent anti-tumor activity was observed in OncoMed’s Phase 1a dose escalation study of brontictuzumab in patients with certain advanced solid tumors, particularly in biomarker-defined patients whose tumors tested positive for overexpression of the activated form of Notch1. Brontictuzumab was generally well tolerated, with the most common adverse event being manageable diarrhea.1
