CytomX presented phase‑1 data on Varsetatug Masetecan (Varseta‑M) in heavily pretreated patients with metastatic colorectal cancer, reporting confirmed overall response rates of 32% (10 mg/kg) and 20% (8.6 mg/kg) and disease control rates of 84–90%. Median progression‑free survival was 7.1 months (10 mg/kg) versus historical controls of 2.0–3.7 months, and the durability of responses was described as compelling. Prophylactic measures and AIBW dosing markedly reduced the rate of severe diarrhea in optimized cohorts; severe treatment‑related adverse events occurred in 25%. Cash of $347 million (cash runway to H2 2028) and planned dose‑optimization data, FDA engagements and combination studies are near‑term milestones. » Más en de.investing.com
