Corbus Pharmaceuticals Appoints Pharma Industry Veteran Brent Pfeiffenberger to Board of Directors

NORWOOD, Mass., May 14, 2026 (GLOBE NEWSWIRE) -- Corbus Pharmaceuticals Holdings, Inc. (NASDAQ:CRBP), a clinical-stage company focused on developing promising new therapies in oncology and obesity, today announced the appointment of Brent Pfeiffenberger, PharmD, MBA, to the Company's Board of Directors.

"Brent is an accomplished pharma industry leader with deep expertise across research, development, and commercialization of life-saving drugs," said Rachelle Jacques, Chair of the Corbus Board of Directors. "His proven record of delivering value-generating commercial successes and steering notable corporate evolutions adds distinctive perspective to the Corbus Board. We look forward to Brent's contributions as we work to advance our CRB-701 and CRB-913 clinical programs."

Dr. Pfeiffenberger is currently President and Chief Executive Officer of Century Therapeutics (NASDAQ:IPSC) and the Chair of its Board of Directors. Prior to joining Century, Dr. Pfeiffenberger served as Chief Operating Officer of Neogene Therapeutics. He played a central role in driving Neogene's evolution from a preclinical company to a global, clinical-stage organization with multiple assets, ultimately culminating in its acquisition by AstraZeneca in 2023. Prior to Neogene, Dr. Pfeiffenberger spent nearly two decades in leadership roles of increasing responsibility at Bristol Myers Squibb, most recently as Senior Vice President, Head of U.S. Oncology, where he oversaw business operations for the multi-billion-dollar franchise. Earlier, he held several critical global leadership positions at Bristol Myers Squibb, building, leading, and expanding commercial and business operations, including serving as Co-Lead, Head of Worldwide Commercial Oncology. In this role, he led strategy and execution for a large-scale oncology portfolio, working in close partnership with Research and Development to shape global development strategies. Dr. Pfeiffenberger received his PharmD from Duquesne University and his MBA from the Wharton School of Business at the University of Pennsylvania.

"I'm impressed with the clinical opportunities presented by CRB-701 in oncology and CRB-913 in obesity, and the Corbus team's strategic cultivation of these assets' markedly differentiated profiles," said Dr. Pfeiffenberger. "With important data readouts for both programs expected this summer, as well as the anticipated initiation of a registrational study for CRB-701, it's a particularly exciting time to join Corbus's board," said Dr. Pfeiffenberger. "I look forward to working with the management team and my fellow Board colleagues as Corbus advances toward critical near- and longer-term milestones."

Updated clinical data from Corbus's Phase 1/2 study of CRB-701, a next generation Nectin-4 ADC, in both head and neck squamous cell carcinoma (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, IL. Corbus recently announced broad alignment with the FDA on the registration path for CRB-701 in HNSCC and expects to initiate a registrational study for CRB-701 in second-line HNSCC this summer. The Company's CANYON-1 Phase 1b dose-ranging 16-week study (n=240) for CRB-913, a highly peripherally restricted oral CB1 inverse agonist, is on track to be completed in the summer of 2026.
