NORWOOD, Mass., June 25, 2025 (GLOBE NEWSWIRE) — Corbus Pharmaceuticals Holdings, Inc. (NASDAQ: CRBP) (“Corbus” or the “Company”), a clinical-stage company focused on oncology and obesity, today announced the dosing of the first participant in the PD-1 combination arm of its Phase 1 study investigating CRB-701 in solid tumors (the Phase 1 Western study). Participants in this arm of the study are being randomized to the 2.7 mg/kg and 3.6 mg/kg cohorts in combination with Keytruda® (pembrolizumab).

“We are very pleased to reach this important milestone and with such an encouraging rate of enrollment in our CRB-701 program,” said Dr. Dominic Smethurst, MA MRCP, Chief Medical Officer of Corbus. “CRB-701 data demonstrates differentiated safety, tolerability and efficacy profiles in HNSCC, cervical and mUC tumors.”

The three-part Phase 1 study (NCT06265727) is evaluating the safety, pharmacokinetics and efficacy of CRB-701 in participants with advanced solid tumors associated with high Nectin-4 expression. The Part A dose escalation of the study evaluated four predetermined doses (1.8 mg/kg, 2.7 mg/kg, 3.6 mg/kg and 4.5 mg/kg Q3W) and is followed by Part B (dose optimization) and Part C (dose expansion). The Company expects to provide a data update and establish the recommended Phase 2 dose (RP2D) in the fourth quarter of this year.
