Corbus Pharmaceuticals Reports Promising Results for CRB-701
Corbus Pharmaceuticals Unveils Efficacy of CRB-701
Corbus Pharmaceuticals Holdings, Inc. (NASDAQ: CRBP) has unveiled significant advancements with CRB-701, a next-generation antibody-drug conjugate, at the recent European Society for Medical Oncology (ESMO25) Congress. This event was pivotal as the company presented compelling data from its Phase 1/2 clinical study of CRB-701, which targets Nectin-4, a tumor-associated antigen linked to various cancers.
Impressive Clinical Results
The results showcased the drug's impressive objective response rates (ORR) in various cancer types. For head and neck squamous cell carcinoma (HNSCC), a noteworthy 47.6% ORR was reported with a dosing of 3.6 mg/kg, while cervical cancer observed a 37.5% ORR. Moreover, in metastatic urothelial cancer (mUC), CRB-701 achieved an exceptional ORR of 55.6% with the same dosage. These results signify CRB-701's potential to offer effective treatment options where conventional therapies have failed.
Safety Profile and Tolerability
An even more encouraging aspect of CRB-701 is its favorable safety and tolerability profile. Across a cohort of 167 patients, no dose-limiting toxicities were reported during the trial. The most common treatment-emergent adverse events included dysgeusia and fatigue; however, the rates were manageable, with only a small fraction experiencing grade 3 adverse events. The low discontinuation rate of 6% underlines CRB-701's potential as a safe option for patients in need.
Detailed Efficacy Across Various Tumor Types
Furthermore, the comprehensive study detailed the efficacy based on a range of factors. The Phase 1/2 study enrolled patients with varying expressions of biomarkers such as Nectin-4, PDL-1, and HPV status. It showed that clinical responses were observed in patients with both high and low expressions of these biomarkers, suggesting that CRB-701 could be effective across a broader patient population.
Next Steps for Corbus Pharmaceuticals
Corbus Pharmaceuticals is not resting on its laurels, as plans are underway to initiate registrational studies for CRB-701 by mid-2026. The company's Chief Medical Officer, Dominic Smethurst, expressed optimism regarding the preliminary efficacy data, recognizing the urgent need for new treatments in HNSCC.
Collaboration and Future Developments
As they move forward, Corbus aims to engage with the FDA and potential stakeholders to discuss the fastest path to market for CRB-701. CEO Yuval Cohen emphasized the importance of collaboration and noted their commitment to updating stakeholders on progress by early 2026.
Engagement and Education Efforts
To further enhance understanding and support around the new treatment, Corbus will host a Key Opinion Leader (KOL) event during ESMO25. This event will feature discussions with leading cancer experts, reinforcing the company’s commitment to education and collaboration in advancing cancer treatment.
