The novel immunomodulatory agent pixatimod (PG545) in combination with the PD-1 inhibitor nivolumab (Opdivo) may benefit patients with advanced bowel cancers, including a small subset of those with colorectal cancer (CRC) considered to be microsatellite stable (MSS), according to early results from a phase Ib trial.
“Although these are results from just a small number of patients, the effect of this drug combination on a cancer subtype known to be inherently resistant to immune checkpoint inhibitors suggest that pixatimod may boost the effectiveness of nivolumab by providing another signal to the immune system, alerting it to these cancers,” Ribas said.
