Jim Winkler, Ph.D., Vice President, Biology at FORMA Therapeutics said, "We are pleased with Celgene’s continued confidence in FORMA’s discovery research. This program represents a potential first-in-class therapeutic mechanism, by conferring both anti-tumor and immune-modulatory effects. We believe the field of protein homeostasis will deliver a promising pipeline of drugs, moving beyond cancer into immuno-oncology, inflammation and neurodegeneration."

About Protein Homeostasis

Protein homeostasis, which is important in oncology, neurodegenerative and other disorders, involves a tightly regulated network of pathways controlling the biogenesis, folding, transport and degradation of proteins. Exploring the maintenance and regulation of such competing, yet integrated, biological pathways using a chemical biology approach, should directly contribute to the understanding of diseases associated with excessive protein misfolding, aggregation and degradation

SORRENTO AND CELULARITY TO START ANTI-CD38 CAR-T PHASE 1 CLINICAL TRIAL
IN PATIENTS WITH RELAPSED OR REFRACTORY MULTIPLE MYELOMA (NCT03464916)

On April 5, 2018 Sorrento Therapeutics, Inc. (NASDAQ: SRNE) and Celularity Inc. reported that the companies have started screening patients for its leading CD38 chimeric antigen receptor (CAR) T cell therapy drug development program, following FDA review allowing clinical trial initiation (Press release, Sorrento Therapeutics, APR 5, 2018, View Source [SID1234525804]).

Phase 1, Open-Label, Dose-Escalation, Pharmacokinetic, and Pharmacodynamic Study of the Safety and Efficacy of CAR2 Anti-CD38 A2 CAR-T Cells in Patients with Relapsed or Refractory Multiple Myeloma (www.clinicaltrials.gov : NCT03464916). IND filing completed. Study cleared for patient enrollment.

The companies’ CD38 CAR-T program is their most advanced program targeting this difficult-to-treat condition. This trial is currently the only active US-based clinical trial targeting CD38 using a CAR-T cell therapy.

The first investigational site at Roger Williams Medical Center, RI, is actively engaged in the clinical study execution, with additional sites to be included.

"Our CD38 CAR-T program has now officially entered clinical stage and will be treating patients as well as collecting valuable data in the upcoming months. This represents a major milestone for Sorrento and Celularity that clearly demonstrates our keen focus on advancing our therapeutics assets as well as our ability to deliver on the timelines we previously communicated" stated Dr. Henry Ji, Chairman and CEO of Sorrento before adding, "we expect to share initial clinical data from this study as soon as it becomes available".

"We are extremely pleased that we can begin this study in our ongoing efforts to improve treatment options for this and other serious diseases. Celularity, created through the contributions from Celgene Corporation, United Therapeutics, Human Longevity Inc., and founding strategic partner Sorrento, is uniquely positioned to combine its platform cellular technology with the vast tool set accessible from Sorrento," said Dr. Robert Hariri, Chairman and CEO of Celularity. "Celularity is building a deep pipeline of immunotherapeutic products from our proprietary placental cells including ‘off-the-shelf’ CAR-T and CAR-NK cell therapies," added Dr. Hariri.

Utilizing available cGMP manufacturing, Sorrento and Celularity estimate they can produce up to 300 patient treatments per year. These existing capacities easily cover the needs of the Phase 1 clinical study and would be sufficient to meet the requirements for subsequent advanced pivotal clinical studies.

Full details about the study available on www.clinicaltrials.gov
