“Our Phase 2 program is designed to explore the activity of RXC004 both as monotherapy and in combination with immune checkpoint inhibitors, consistent with its postulated dual mechanism of action. Our primary efficacy hypothesis is that in combination it can overcome immune evasion and anti-PD-1 resistance, which could open new patient segments,” said Dr Jane Robertson, Chief Medical Officer, Redx Pharma. “While today’s results do not support further clinical development of RXC004 as monotherapy in recurrent BTC, where very few drugs have received regulatory approval as single agents in this hard-to-treat disease, they are nonetheless consistent with the overall hypothesis that RXC004 has potential as an active component of combination therapy. We look forward to the data read out from the combination module with pembrolizumab, that is expected in the second half of this year.”
