Vorbipiprant (CR6086) / Balstilimab (AGEN2034) Combination in Stage IV Refractory pMMR - MSS CRC, and Other Metastatic GI Cancers

Summary

This Phase Ib/IIa study comprises a Main Study and a Study Extension. The Main Study has been designed according to a 3+3 Dose Escalation/dose Expansion design in refractory pMMR-MSS mCRC patients. The fixed-dose Expansion phase will be conducted at the recommended dose for expansion (RDE), with the purpose of generating additional and more robust safety and efficacy data. 27 patients are predicted in the Dose Escalation phase and 52 in the Expansion phase, respectively. The Study Extension explores in other metastatic GI cancers the Vorbipiprant (CR6086) RDE obtained in the Main Study. 27 patients are predicted. No control arm was included, as the target patient population of this study consists of patients in whom the overall survival is less than 6 months and treatment options are very limited and often poorly tolerated, making unlikely that the study results can be significantly biased.
