Janssen Announces Initiation of Phase 1b/2 Clinical Development Program Evaluating JNJ-68284528 CAR-T Cells for the Treatment of Multiple Myeloma

Spring House, PA (May 30, 2018) – The Janssen Pharmaceutical Companies of Johnson & Johnson announced today the initiation of a Phase 1b/2 clinical development program studying JNJ-68284528 (developed based on Legend’s LCAR-B38M), a chimeric antigen receptor T cell (CAR-T) therapy directed against B cell maturation antigen (BCMA), in patients with relapsed or refractory multiple myeloma. The planned start of the Phase 1b/2 study (68284528MMY2001), scheduled to begin enrollment in the second half of 2018, follows the U.S. Food and Drug Administration (FDA) clearance of the Investigational New Drug (IND) application submitted by Janssen.

As announced in December 2017, Janssen entered into a worldwide collaboration and license agreement with Legend Biotech USA Inc. and Legend Biotech Ireland Limited (“Legend”), subsidiaries of GenScript Biotech Corporation. Under the terms of the agreement, Legend granted Janssen Biotech, Inc. a worldwide license to jointly develop and commercialize JNJ-68284528 in multiple myeloma.

“We are committed to rapidly advancing JNJ-68284528, and we are pleased to initiate a global clinical development program to further evaluate this cell-based therapy,” said Peter F. Lebowitz, M.D., Ph.D., Global Therapeutic Area Head, Oncology, Janssen Research & Development, LLC. “As we strive to eliminate multiple myeloma, we are hopeful that this BCMA targeted CAR-T therapy will play an important role in the treatment of this disease.”

The Phase 1b/2, open-label, multicenter study will evaluate the safety and efficacy of JNJ-68284528 in adults with relapsed or refractory multiple myeloma. The primary objective of the Phase 1b portion of the study is to characterize the safety and establish the dose of JNJ-68284528, which was informed by the first-in-human study with LCAR-B38M CAR-T cells (Legend-2). The primary objective for the Phase 2 portion of the study is to evaluate the efficacy of JNJ-68284528 (primary endpoint: overall response rate [partial response or better] as defined by the International Myeloma Working Group response criteria).

About CAR-T and BCMA

CAR-T cells are an innovative approach to eradicating cancer cells by harnessing the power of a patient’s own immune system. BCMA is a protein that is highly expressed on myeloma cells. By targeting BCMA via a CAR-T approach, CAR-T therapies may have the potential to redefine the treatment paradigm for multiple myeloma and potentially advance towards cures for patients with the disease.

About Multiple Myeloma

Multiple myeloma is an incurable blood cancer that occurs when malignant plasma cells grow uncontrollably in the bone marrow.[1],[2] Refractory cancer occurs when a patient's disease is resistant to treatment or in the case of multiple myeloma, patients progress within 60 days of their last therapy.[3],[4] Relapsed cancer means the disease has returned after a period of initial, partial or complete remission.[5] In 2018, it is estimated that 30,700 people will be diagnosed and 12,770 will die from the disease in the United States.[6] Most patients are diagnosed due to symptoms, which can include bone fracture or pain, low red blood counts, fatigue, calcium elevation, kidney problems or infections.[7]
