Nektar Therapeutics and Bristol-Myers Squibb Announce U.S. FDA Breakthrough Therapy Designation for Bempegaldesleukin (NKTR-214) in Combination with Opdivo® (nivolumab) for the Treatment of Patients with Untreated Advanced Melanoma
August 01, 2019 -- Nektar Therapeutics (Nasdaq: NKTR) and Bristol-Myers Squibb (NYSE: BMY) today announced that the U.S. Food and Drug Administration (FDA) has granted Breakthrough Therapy Designation for investigational agent bempegaldesleukin (NKTR-214) in combination with Bristol-Myers Squibb's Opdivo®(nivolumab) for the treatment of patients with previously untreated unresectable or metastatic melanoma. The Breakthrough Therapy Designation is based on clinical data which were recently reported at the 2019 American Society of Clinical Oncology (ASCO) Annual Meeting from the cohort of patients with metastatic melanoma that were treated with the doublet therapy in the ongoing PIVOT-02 Phase 1/2 clinical study.
FDA Breakthrough Therapy Designation is intended to expedite the development and review of medicines aimed at treating a serious or life-threatening disease where there is preliminary clinical evidence that the investigational therapy may offer substantial improvement over existing therapies on at least one clinically significant endpoint.
Bempegaldesleukin, Nektar's lead immuno-oncology candidate, is an investigational CD122-preferential IL-2 pathway agonist designed to provide activation and proliferation of cancer-killing immune cells, known as CD8+ effector T cells and natural killer (NK) cells. A Phase 3 clinical trial evaluating bempegaldesleukin in combination with nivolumab versus nivolumab in first-line advanced melanoma patients is currently recruiting patients (NCT03635983).
"In collaboration with our partner Bristol-Myers Squibb, we plan to work closely with FDA as we continue to advance our development program of bempegaldesleukin in combination with nivolumab in advanced melanoma patients," said Dr. Stephen Doberstein, SVP, Research and Development and Chief R&D Officer of Nektar Therapeutics. "Our teams are encouraged by the deepening of responses we observed in patients with previously untreated advanced melanoma who received the doublet therapy in our PIVOT-02 study. We look forward to continuing to provide updated results at a future medical meeting as the data mature further in this ongoing cohort of melanoma patients."
In February 2018, Bristol-Myers Squibb and Nektar executed a global strategic development and commercialization collaboration for bempegaldesleukin.
About Bempegaldesleukin (NKTR-214)
Bempegaldesleukin is designed to stimulate cancer-killing immune cells in the body by targeting CD122 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

Bristol-Myers Squibb: Advancing Oncology Research
At Bristol-Myers Squibb, patients are at the center of everything we do. The focus of our research is to increase quality, long-term survival for patients and make cure a possibility. Through a unique multidisciplinary approach powered by translational science, we harness our deep scientific experience in oncology and Immuno-Oncology (I-O) research to identify novel treatments tailored to individual patient needs. Our researchers are developing a diverse, purposefully built pipeline designed to target different immune system pathways and address the complex and specific interactions between the tumor, its microenvironment and the immune system. We source innovation internally, and in collaboration with academia, government, advocacy groups and biotechnology companies, to help make the promise of transformational medicines, like I-O, a reality for patients.
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 60 countries, including the United States and the European Union.
