Bristol-Myers Squibb Company announced the companies have executed a global strategic development and commercialization collaboration for Nektar’s lead immuno-oncology program, NKTR-214.
Under the collaboration, the companies will jointly develop and commercialize NKTR-214 in combination with Bristol-Myers Squibb’s Opdivo (nivolumab) and Opdivo plus Yervoy (ipilimumab) in more than 20 indications across 9 tumor types, as well as potential combinations with other anti-cancer agents from either of the respective companies and/or third parties.
NKTR-214, a CD122-biased agonist, is an investigational immuno-stimulatory therapy designed to selectively expand cancer-fighting T cells and natural killer (NK) cells directly in the tumor micro-environment and increase PD-1 expression on those immune cells.
“We are excited to bring our leading capabilities and expertise in developing cancer therapies together with Nektar’s innovative science to jointly develop and commercialize NKTR-214 in combination with Opdivo and Opdivo plus Yervoy,” said Giovanni Caforio, M.D., Chairman and CEO, Bristol-Myers Squibb. “Bristol-Myers Squibb has established Opdivo plus Yervoy as the only approved immunotherapy combination for cancer patients and built a robust oncology pipeline.
With this commitment to the development of NKTR-214, an investigational therapy designed with a unique approach to harnessing the full potential of the interleukin-2 pathway, we now have a third validated I-O mechanism that has demonstrated a clinical benefit in patients, and holds significant potential to expand the benefits that these immuno-oncology agents can bring to patients with cancer.”
Bristol-Myers Squibb and Nektar have agreed to a joint clinical development plan to evaluate NKTR-214 with Opdivo and Opdivo plus Yervoy in registration-enabling clinical trials in more than 20 indications in 9 tumor types including melanoma, renal cell carcinoma, non-small cell lung cancer, bladder and triple negative breast cancer. Pivotal studies in renal cell carcinoma and melanoma are expected to be initiated in mid-2018.
“Bristol-Myers Squibb, the global leader in immuno-oncology, is the ideal collaborator to enable us to establish NKTR-214 as a backbone immunotherapy in the treatment of cancer,” said Howard Robin, President & CEO of Nektar. “NKTR-214’s ability to grow tumor infiltrating lymphocytes (TILs) in vivo and replenish the immune system is critically important as many patients battling cancer lack sufficient TIL populations to benefit from approved checkpoint inhibitor therapies.
This strategic collaboration allows us to very quickly develop NKTR-214 with the leading approved PD-1 immune checkpoint inhibitor in numerous registrational trials. We look forward to our continued relationship with Bristol-Myers Squibb as we work together to advance cancer treatment for patients around the world.”
Transaction Terms
Under the terms of the agreement, Bristol-Myers Squibb will make an upfront cash payment of $1.0 billion and an equity investment of $850 million (8,284,600 shares of Nektar’s common stock at $102.60 per share). Bristol-Myers Squibb has agreed to certain lock-up, standstill and voting provisions on its share ownership for a period of five years subject to certain specified exceptions.
Nektar is also eligible to receive an additional $1.78 billion in milestones, of which $1.43 billion are development and regulatory milestones and the remainder are sales milestones. Nektar will book revenue for worldwide sales of NKTR-214 and the companies will split global profits for NKTR-214 with Nektar receiving 65% and Bristol-Myers Squibb 35%. Bristol-Myers Squibb will retain 100% of product revenues for its own medicines. The parties also will share development costs relative to their ownership interest of medicines included in the trials. For trials in the joint clinical development plan that include NKTR-214 with Opdivo only, the parties will share development costs with 67.5% allocated to Bristol-Myers Squibb and 32.5% allocated to Nektar. For trials in the joint clinical development plan that include NKTR-214 with Opdivo and Yervoy, the parties will share development costs with 78% allocated to Bristol-Myers Squibb and 22% allocated to Nektar.
Both Bristol-Myers Squibb and Nektar have agreed for a specified period of time to not commence development with overlapping mechanisms of action in the same indications as those included in the joint clinical development plan. The parties are otherwise free to develop NKTR-214 with their own pipeline assets and/or any other third party compounds. Both parties have agreed to initiate registration-enabling studies in the joint clinical development plan within 14 months of the effective date of the agreement, subject to allowable delays.
Both parties will jointly commercialize NKTR-214 on a global basis. Bristol-Myers Squibb will lead global commercialization activities for NKTR-214 combinations with Bristol-Myers Squibb medicines and Nektar will co-commercialize such combinations in the US, major EU markets and Japan. Nektar will lead global commercialization activities for NKTR-214 combinations with either Nektar medicines and/or other third-party medicines.
For Bristol-Myers Squibb, the transactions are expected to be dilutive in 2018 and 2019 to the company’s non-GAAP EPS by $0.02 and $0.10, respectively. Nektar and Bristol-Myers Squibb currently expect to complete the transaction during the second quarter of 2018, subject to the expiration or termination of applicable waiting periods under all applicable US antitrust laws and the satisfaction of other usual and customary closing conditions. Further details of the agreement can be found in Nektar’s Form 8-K filed today with the Securities and Exchange Commission. Sidley Austin LLP is acting as legal counsel to Nektar for the strategic collaboration agreement and equity investment.
Nektar and Bristol-Myers Squibb entered into a clinical collaboration in September of 2016 to evaluate the potential for the combination of Opdivo and NKTR-214 to show improved and sustained efficacy and tolerability above the current standard of care. The Phase 1/2 PIVOT clinical study is ongoing in over 350 patients with melanoma, kidney, non-small cell lung cancer, bladder, and triple-negative breast cancers.
eptors found on the surface of these immune cells, known as CD8+ effector T cells and Natural Killer (NK) cells. Growing these tumor-infiltrating lymphocytes (TILs) in vivo and replenishing the immune system is critically important as many patients battling cancer lack sufficient TIL populations to benefit from approved checkpoint inhibitor therapies. In preclinical studies, treatment with NKTR-214 resulted in a rapid expansion of these cells and mobilization into the tumor micro-environment.1,2 NKTR-214 has an antibody-like dosing regimen similar to the existing checkpoint inhibitor class of approved medicines.
Bristol-Myers Squibb & Immuno-Oncology: Advancing Oncology Research
At Bristol-Myers Squibb, patients are at the center of everything we do. Our vision for the future of cancer care is focused on researching and developing transformational Immuno-Oncology (I-O) medicines for hard-to-treat cancers that could potentially improve outcomes for these patients.
We are leading the scientific understanding of I-O through our extensive portfolio of investigational compounds and approved agents. Our differentiated clinical development program is studying broad patient populations across more than 50 types of cancers with 14 clinical-stage molecules designed to target different immune system pathways. Our deep expertise and innovative clinical trial designs position us to advance I-O/I-O, I-O/chemotherapy, I-O/targeted therapies and I-O radiation therapies across multiple tumors and potentially deliver the next wave of therapies with a sense of urgency. We also continue to pioneer research that will help facilitate a deeper understanding of the role of immune biomarkers and how patients’ tumor biology can be used as a guide for treatment decisions throughout their journey.
We understand making the promise of I-O a reality for the many patients who may benefit from these therapies requires not only innovation on our part but also close collaboration with leading experts in the field. Our partnerships with academia, government, advocacy and biotech companies support our collective goal of providing new treatment options to advance the standards of clinical practice.
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 enrolled more than 25,000 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 60 countries, including the United States, the European Union and Japan. 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 the Bristol-Myers Squibb and Ono Pharmaceutical Co., Ltd. Collaboration
In 2011, through a collaboration agreement with Ono Pharmaceutical Co., Ltd. (Ono), Bristol-Myers Squibb expanded its territorial rights to develop and commercialize Opdivo globally except in Japan, South Korea and Taiwan, where Ono had retained all rights to the compound at the time. On July 23, 2014, Bristol-Myers Squibb and Ono further expanded the companies’ strategic collaboration agreement to jointly develop and commercialize multiple immunotherapies – as single agents and combination regimens – for patients with cancer in Japan, South Korea and Taiwan.
