Array BioPharma Announces Strategic Collaboration with Pfizer
The companies are entering into this collaboration to explore the potential benefits of combining molecularly targeted therapeutics with the body's innate cancer-fighting abilities using immunotherapy.
"Array is excited to announce this partnership with Pfizer, an established global leader in Oncology therapeutics," said Ron Squarer, Chief Executive Officer,
"Preclinical data indicate that combining binimetinib with an immune checkpoint inhibitor and talazoparib could be a rational combination to test in the clinic," said
Under the terms of the agreement, Array and Pfizer will collaborate on a Phase 1b clinical trial to explore a series of novel combinations, investigating the safety and efficacy of the combination of binimetinib, avelumab and talazoparib across various tumor types. A multi-arm clinical trial is expected to establish recommended doses of different regimens combining the drugs. Initially the focus will be in non-small cell lung cancer (NSCLC) and pancreatic cancer, and additional indications will be explored at a later stage. The study is expected to begin by the third quarter of 2018, and results will be used to determine optimal approaches to further clinical development of these combinations.
Under the collaboration agreement, the trial will be sponsored and funded by Pfizer, with Array providing binimetinib supply.
*Avelumab is jointly developed by
MEK is a key protein kinase in the MAPK signaling pathway (RAS-RAF-MEK-ERK). Research has shown this pathway regulates several key cellular activities including proliferation, differentiation, survival and angiogenesis. Inappropriate activation of proteins in this pathway has been shown to occur in many cancers, such as melanoma, colorectal and thyroid cancers. Binimetinib is a late-stage, small molecule MEK inhibitor which targets key enzymes in this pathway. Binimetinib is an investigational medicine and is not currently approved in any country.
Binimetinib is being studied in clinical trials in advanced cancer patients, including the Phase 3 COLUMBUS trial in patients with BRAF-mutant melanoma and the Phase 3 BEACON CRC trial in patients with BRAF V600E-mutant colorectal cancer.
Avelumab is a human anti-programmed death ligand-1 (PD-L1) antibody. Avelumab has been shown in preclinical models to engage both the adaptive and innate immune functions. By blocking the interaction of PD-L1 with PD-1 receptors, avelumab has been shown to release the suppression of the T cell-mediated antitumor immune response in preclinical models. Avelumab has also been shown to induce NK cell-mediated direct tumor cell lysis via antibody-dependent cell-mediated cytotoxicity (ADCC) in vitro. In
Avelumab is currently being evaluated in the JAVELIN clinical development program, which involves at least 30 clinical programs, including nine Phase III trials, and more than 7,000 patients across more than 15 different tumor types, including gastric/gastroesophageal junction, non-small cell lung cancer, renal cell carcinoma and ovarian cancer. For a comprehensive list of all avelumab trials, please visit clinicaltrials.gov.
Indications in the US
Important Safety Information from the US FDA Approved Label
The warnings and precautions for BAVENCIO include immune-mediated adverse reactions (such as pneumonitis, hepatitis, colitis, endocrinopathies, nephritis and renal dysfunction and other adverse reactions), infusion-related reactions and embryo-fetal toxicity.
Common adverse reactions (reported in at least 20% of patients) in patients treated with BAVENCIO for mMCC and patients with locally advanced or metastatic UC include fatigue, musculoskeletal pain, diarrhea, nausea, infusion-related reaction, peripheral edema, decreased appetite/hypophagia, urinary tract infection and rash.
For full prescribing information and medication guide for BAVENCIO, please see www.BAVENCIO.com.
Talazoparib is an investigational anti-cancer compound called a PARP (poly ADP ribose polymerase) inhibitor. Preclinical studies suggest that talazoparib is highly potent and has a dual mechanism of action, with the potential to induce tumor cell death by blocking PARP enzyme activity and trapping PARP on the sites of DNA damage. Talazoparib is currently being evaluated in advanced germline (inherited) BRCA+ breast cancer as well as other cancer types with deficiencies in DNA damage repair (DDR). Talazoparib has not been approved by any regulatory authorities for the treatment of any disease.
