On February 13, 2020 Bristol-Myers Squibb Company (NYSE: BMY) reported that the U.S. Food and Drug Administration (FDA) has accepted for Priority Review its Biologics License Application (BLA) for lisocabtagene maraleucel (liso-cel), the company’s autologous anti-CD19 chimeric antigen receptor (CAR) T-cell immunotherapy with a defined composition of purified CD8+ and CD4+ CAR T cells for the treatment of adult patients with relapsed or refractory (R/R) large B-cell lymphoma after at least two prior therapies (Press release, Bristol-Myers Squibb, FEB 13, 2020, View Source [SID1234554259]). The FDA has set a Prescription Drug User Fee Act (PDUFA) goal date of August 17, 2020.

"There remains a critical need for additional therapies in large B-cell lymphoma, particularly for relapsed or refractory patients," said Stanley Frankel, M.D., senior vice president, Cellular Therapy Development, Bristol-Myers Squibb. "Based on the TRANSCEND NHL 001 data, liso-cel has the potential to expand treatment options for those affected by this aggressive blood cancer who did not respond to initial therapies or whose disease has relapsed. This BLA acceptance and Priority Review designation is an important step as we work to improve treatment for these patients in need."

The BLA, submitted by Juno Therapeutics, a wholly owned subsidiary of Bristol-Myers Squibb Company, is based on the safety and efficacy results from the TRANSCEND NHL 001 trial, evaluating liso-cel in 268 patients with R/R large B-cell lymphoma, including diffuse large B-cell lymphoma (DLBCL), high-grade lymphoma, primary mediastinal B-cell lymphoma and Grade 3B follicular lymphoma. TRANSCEND NHL 001 is the largest study of CD19-directed CAR T cells to support a BLA to date and was recently the subject of an oral presentation at the 61st American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting and Exposition.

According to the FDA, a Priority Review designation will direct overall attention and resources to the evaluation of applications for drugs that, if approved, would be significant improvements in the safety or effectiveness of the treatment, diagnosis, or prevention of serious conditions when compared to standard applications.

Liso-cel was previously granted Breakthrough Therapy and Regenerative Medicine Advanced Therapy designations by the FDA for R/R aggressive large B-cell non-Hodgkin lymphoma, including DLBCL, not otherwise specified (de novo or transformed from indolent lymphoma), PMBCL or Grade 3B FL, and Priority Medicines (PRIME) scheme by the European Medicines Agency for R/R DLBCL.

Liso-cel is an investigational compound that is not approved for use in any country.

About Large B-cell Lymphoma

Diffuse large B-cell lymphoma (DLBCL) is the most common of large B-cell lymphomas. It is an aggressive form of non-Hodgkin lymphoma (NHL), accounting for three out of every five cases. Approximately one-third of patients with DLBCL relapse after receiving first-line treatment, and about 10% have refractory disease. Historically, median life expectancy for patients who relapse or are refractory to current standard of care treatments is approximately six months.

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 quality, 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 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.

About Lisocabtagene Maraleucel (liso-cel)

Liso-cel is an investigational chimeric antigen receptor (CAR) T-cell therapy designed to target CD19, which is a surface glycoprotein expressed during normal B-cell development and maintained following malignant transformation of B cells. Liso-cel aims to target CD19-expressing cells through a CAR construct that includes an anti-CD19 single-chain variable fragment (scFv) targeting domain for antigen specificity, a transmembrane domain, a 4-1BB costimulatory domain hypothesized to increase T-cell proliferation and persistence, and a CD3-zeta T-cell activation domain. The defined composition of CAR-positive viable T-cells (consisting of CD8 and CD4 components) in liso-cel may reduce product variability; however, the clinical significance of defined composition is unknown.

About TRANSCEND NHL 001

TRANSCEND NHL 001 is an open-label, multicenter, pivotal phase 1 study to determine the safety, antitumor activity, and pharmacokinetics of liso-cel in patients with R/R B-cell NHL, including DLBCL, HGL, PMBCL, Grade 3B FL. Mantle cell lymphoma is investigated in a separate cohort. The primary outcome measures included treatment-related adverse events, dose-limiting toxicities and objective response rate. Key secondary outcome measures included complete response rate, duration of response, and progression-free survival. The TRANSCEND program is a broad clinical program evaluating liso-cel in multiple disease states and treatment stages.
