Corbus Pharmaceuticals Announces Broad Alignment with FDA on Registration Path for CRB-701 in Second-Line HNSCC and Cervical Cancer
FDA feedback enables Corbus to proceed with proposed registrational study design and endpoints to support potential accelerated approval in second-line HNSCC and cervical cancer
Updated CRB-701 monotherapy data accepted for presentation at ASCO 2026
Dr. Dominic Smethurst to step down as Corbus’ Chief Medical Officer on June 30, 2026
Norwood, MA, April 7, 2026 (GLOBE NEWSWIRE) -- Corbus Pharmaceuticals Holdings, Inc. (NASDAQ: CRBP), a clinical-stage company focused on promising new therapies in oncology and obesity, today announced broad alignment with the U.S. Food and Drug Administration (FDA) on the registration path for CRB-701, the Company’s next-generation, highly stable Nectin-4 targeting ADC, in head and neck squamous cell carcinoma (HNSCC) and cervical cancer. Corbus also announced that Dr. Dominic Smethurst, MA, MRCP is stepping down from his role as Chief Medical Officer; his last day with the company will be June 30, 2026.
The agreed upon second-line registrational study designs for CRB-701 include:
Updated clinical data from the Phase 1/2 study of CRB-701 in both HNSCC and cervical cancer will be presented at the upcoming 2026 American Society of Clinical Oncology (ASCO) Annual Meeting to be held May 29 – June 2 in Chicago. Data will include clinical response durability as well as HNSCC patient subgroup analysis. Corbus previously presented dose optimization data from the study, including encouraging efficacy and safety findings, at the 2025 European Society for Medical Oncology Congress (ESMO 2025). The company also anticipates reporting data with CRB-701 in combination with Keytruda® in first-line HNSCC patients in Q4 2026 to support potential further registration-enabling trials.
“We’re pleased to share this important regulatory update as we continue to progress CRB-701 as a novel oncology therapeutic to address unmet medical needs for patients. We look forward to sharing updated monotherapy data on CRB-701 at ASCO and expect to initiate a registrational study for CRB-701 in second-line HNSCC in mid-2026,” said Yuval Cohen, Ph.D., Chief Executive Officer of Corbus.
Dr. Cohen continued, “This milestone marks an important transition from clinical proof of concept to pending late-stage registrational development and the potential for regulatory submission of CRB-701. This year we will be adding several key new senior leaders to best prepare us for this critical next phase. We are very grateful for Dr. Smethurst’s contributions to advance our pipeline programs through early development, well positioning Corbus for continued success.”
