BLA submission based on results from pivotal Phase 2 KarMMa study evaluating ide-cel in heavily pre-treated patient population

Companies are committed to working with the FDA to rapidly advance ide-cel through the regulatory review process

PRINCETON, N.J., & CAMBRIDGE, Mass.--(BUSINESS WIRE)--Jul. 29, 2020-- Bristol Myers Squibb (NYSE: BMY) and bluebird bio, Inc. (Nasdaq: BLUE) today announced the submission of their Biologics License Application (BLA) to the U.S. Food and Drug Administration (FDA) for idecabtagene vicleucel (ide-cel; bb2121), the companies’ investigational B-cell maturation antigen (BCMA)-directed chimeric antigen receptor (CAR) T cell immunotherapy, for the treatment of adult patients with relapsed and refractory multiple myeloma. This submission provides further details on the Chemistry, Manufacturing and Controls (CMC) module to address the outstanding regulatory requests from the FDA in May 2020 following the original BLA submission from March 2020.

The submission is based on results from the pivotal Phase 2 KarMMa study evaluating the efficacy and safety of ide-cel in relapsed and refractory multiple myeloma patients exposed to an immunomodulatory (IMiD) agent, a proteasome inhibitor (PI) and an anti-CD38 antibody. Results from the study were shared during an oral presentation as part of the American Society of Clinical Oncology 2020 (ASCO20) Virtual Scientific Program.¹

Multiple myeloma is a cancer of plasma cells.² The cause of multiple myeloma is not known and currently there is no cure; however, there are a number of treatment options available that can lead to response.² Patients who have already been treated with some available therapies but continue to have progression of their disease have “relapsed” and “refractory” multiple myeloma, meaning their cancer has returned after they have received initial treatments. Patients with relapsed and refractory multiple myeloma that have been exposed to all three major drug classes, including an IMiD agent, a PI and an anti-CD38 antibody, have fewer treatment options and poor outcomes, including shorter response durations and lower overall survival.³

Ide-cel was granted Breakthrough Therapy Designation (BTD) by the FDA, and PRIority MEdicines (PRIME) designation and validation of its Marketing Authorization Application (MAA) by the European Medicines Agency for relapsed and refractory multiple myeloma.

Ide-cel is not approved for any indication in any geography.

For Holders of Contingent Value Rights (CVR), Ticker BMY-RT

U.S. FDA approval of ide-cel by March 31, 2021 is one of the required remaining milestones of the Contingent Value Rights issued upon the close of the Celgene acquisition in the fourth quarter of 2019. The other is U.S. FDA approval of liso-cel by December 31, 2020. The company is committed to working with FDA to progress both applications and achieve the remaining regulatory milestones required by the CVR.

About Ide-cel

Ide-cel is a B-cell maturation antigen (BCMA)-directed genetically modified autologous chimeric antigen receptor (CAR) T cell immunotherapy. The ide-cel CAR is comprised of a murine extracellular single-chain variable fragment (scFv) specific for recognizing BCMA, attached to a human CD8 α hinge and transmembrane domain fused to the T cell cytoplasmic signaling domains of CD137 4-1BB and CD3-ζ chain, in tandem. Ide-cel recognizes and binds to BCMA on the surface of multiple myeloma cells leading to CAR T cell proliferation, cytokine secretion, and subsequent cytolytic killing of BCMA-expressing cells.

Ide-cel is being developed as part of a Co-Development, Co-Promotion and Profit Share Agreement between Bristol Myers Squibb and bluebird bio. Ide-cel was granted accelerated assessment by the European Medicines Agency (EMA) on March 26, 2020, and the MAA was validated by the EMA on May 20, 2020.

About KarMMa

KarMMa (NCT03361748) is a pivotal, open-label, single-arm, multicenter, multinational, Phase 2 study evaluating the efficacy and safety of ide-cel in adults with relapsed and refractory multiple myeloma in North America and Europe. The primary endpoint of the study is overall response rate as assessed by an independent review committee (IRC) according to the International Myeloma Working Group (IMWG) criteria. Complete response rate is a key secondary endpoint. Other efficacy endpoints include time to response, duration of response, progression-free survival, overall survival, minimal residual disease evaluated by Next-Generation Sequencing (NGS) assay and safety. The study enrolled 140 patients, of whom 128 received ide-cel across the target dose levels of 150-450 x 10⁶ CAR+ T cells after receiving lymphodepleting chemotherapy. All enrolled patients had received at least three prior treatment regimens, including an immunomodulatory agent, a proteasome inhibitor and an anti-CD38 antibody, and were refractory to their last regimen, defined as progression during or within 60 days of their last therapy.

Bristol Myers Squibb: Advancing Cancer Research

At Bristol Myers Squibb, patients are at the center of everything we do. The goal of our cancer research is to increase patients’ quality of life, long-term survival and make cure a possibility. We harness our deep scientific experience, cutting-edge technologies and discovery platforms to discover, develop and deliver novel treatments for patients.

Building upon our transformative work and legacy in hematology and Immuno-Oncology that has changed survival expectations for many cancers, our researchers are advancing a deep and diverse pipeline across multiple modalities. In the field of immune cell therapy, this includes registrational CAR T cell agents for numerous diseases, and a growing early-stage pipeline that expands cell and gene therapy targets, and technologies. We are developing cancer treatments directed at key biological pathways using our protein homeostasis platform, a research capability that has been the basis of our approved therapies for multiple myeloma and several promising compounds in early- to mid-stage development. Our scientists are targeting different immune system pathways to address interactions between tumors, the microenvironment and the immune system to further expand upon the progress we have made and help more patients respond to treatment. Combining these approaches is key to delivering potential new options for the treatment of cancer and addressing the growing issue of resistance to immunotherapy. We source innovation internally, and in collaboration with academia, government, advocacy groups and biotechnology companies, to help make the promise of transformational medicines a reality for patients.
