Xilio Therapeutics Unveils Late-Breaking Phase 2 Results for Vilastobart in MSS mCRC Patients with Elevated Plasma Tumor Mutational Burden at the 40th Annual SITC Meeting
Clinical Trial Results: Xilio Therapeutics reported a 40% objective response rate (ORR) in heavily pre-treated patients with microsatellite stable (MSS) metastatic colorectal cancer (mCRC) without liver metastases and high plasma tumor mutational burden (TMB) in their Phase 2 trial of vilastobart combined with atezolizumab.
Plasma TMB as a Biomarker: Approximately 55% of patients with MSS CRC are estimated to have high plasma TMB, indicating a significant population that may benefit from the combination treatment, highlighting the potential of plasma-based TMB as a predictive biomarker for response.
Safety Profile: The combination therapy of vilastobart and atezolizumab demonstrated a well-tolerated safety profile, with most treatment-related adverse events being Grade 1 or 2, and only a small percentage of patients discontinuing treatment due to adverse effects.
Future Plans: Xilio is seeking partnerships to further develop vilastobart in combination with PD-(L)1 or PD1-VEGF therapies for MSS CRC and other tumor types, following the promising results from the clinical trial.
