SAN FRANCISCO - Nektar Therapeutics (Nasdaq: NKTR) and Bristol-Myers Squibb Company (NYSE: BMY) announced today the companies have agreed to a new joint development plan to advance bempegaldesleukin (bempeg) plus Opdivo (nivolumab) into multiple new registrational trials.
The revision to the strategic collaboration agreement includes a new joint development plan under which Nektar and Bristol-Myers Squibb will expand the active clinical development program for bempeg plus nivolumab from three ongoing registrational trials in first-line metastatic melanoma, first-line cisplatin-ineligible metastatic urothelial cancer and first-line metastatic renal cell carcinoma (RCC) to include two additional registrational trials in adjuvant melanoma and in muscle-invasive bladder cancer. In addition, a Phase 1/2 dose escalation and expansion study will be initiated to evaluate bempeg plus nivolumab in combination with axitinib in first-line RCC in order to support a future registrational trial. The costs for these studies will be shared based upon the cost-sharing outlined in the terms of the original collaboration agreement. Also as part of the new strategic collaboration agreement, Bristol-Myers Squibb will independently conduct and fund a Phase 1/2 dose optimization and expansion study in first-line non-small-cell lung cancer with bempeg and nivolumab.
'Bristol-Myers Squibb and Nektar view bempeg as an important asset and IL-2 as an important target,' said Fouad Namouni, M.D., head of oncology development, Bristol-Myers Squibb. 'We look forward to expanding the registrational program currently underway for bempeg and are committed to the development of potential new combination therapies to address the unmet needs of patients living with cancer.'
'We are pleased to move forward with this new set of registrational trials for bempeg, including the addition of an important Phase 3 study in adjuvant melanoma which builds on the existing metastatic melanoma study and our Breakthrough Therapy Designation,' said Nektar President & CEO Howard W. Robin. 'We now have a comprehensive plan to target multiple indications and have the opportunity to continue to collaborate on development with other companies in indications outside of those in the BMS and Nektar joint development program.'
About Opdivo
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's leading global development program is based on Bristol-Myers Squibb's scientific expertise in the field of Immuno-Oncology, and includes a broad range of clinical trials across all phases, including Phase 3, in a variety of tumor types. To date, the Opdivo clinical development program has treated more than 35,000 patients. The Opdivo trials have contributed to gaining a deeper understanding of the potential role of biomarkers in patient care, particularly regarding how patients may benefit from Opdivo across the continuum of PD-L1 expression.
In July 2014, Opdivo was the first PD-1 immune checkpoint inhibitor to receive regulatory approval anywhere in the world. Opdivo is currently approved in more than 65 countries, including the United States, the European Union, Japan and China. In October 2015, the Company's Opdivo and Yervoy combination regimen was the first Immuno-Oncology combination to receive regulatory approval for the treatment of metastatic melanoma and is currently approved in more than 50 countries, including the United States and the European Union.
About Yervoy
Yervoy is a recombinant, human monoclonal antibody that binds to the cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4). CTLA-4 is a negative regulator of T-cell activity. Yervoy binds to CTLA-4 and blocks the interaction of CTLA-4 with its ligands, CD80/CD86. Blockade of CTLA-4 has been shown to augment T-cell activation and proliferation, including the activation and proliferation of tumor infiltrating T-effector cells. Inhibition of CTLA-4 signaling can also reduce T-regulatory cell function, which may contribute to a general increase in T-cell responsiveness, including the anti-tumor immune response. On March 25, 2011, the U.S. Food and Drug Administration (FDA) approved Yervoy 3 mg/kg monotherapy for patients with unresectable or metastatic melanoma. Yervoy is approved for unresectable or metastatic melanoma in more than 50 countries. There is a broad, ongoing development program in place for Yervoy spanning multiple tumor types.

About Bempegaldesleukin (BEMPEG, NKTR-214)
Bempeg is an investigational, first-in-class, CD122-preferential IL-2 pathway agonist designed to provide rapid activation and proliferation of cancer-killing immune cells, known as CD8+ effector T cells and natural killer (NK) cells, without over activating the immune system. The agent is designed to stimulate these cancer-killing immune cells in the body by targeting CD122-specific receptors found on the surface of these immune cells. CD122, which is also known as the Interleukin-2 receptor beta subunit, is a key signaling receptor that is known to increase proliferation of these effector T cells.1 In clinical and preclinical studies, treatment with bempegaldesleukin resulted in expansion of these cells and mobilization into the tumor micro-environment.2,3 Bempegaldesleukin has an antibody-like dosing regimen similar to the existing checkpoint inhibitor class of approved medicines.
