New drug duo takes on multiple cancers in Mid-Stage trial
NCT ID NCT05642780
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This phase 2 study is testing a combination of two drugs, SKB264 and pembrolizumab (Keytruda), in 240 people with certain advanced solid tumors, including cervical, urothelial, ovarian, prostate, and endometrial cancers. The goal is to see if the combination is safe and effective at shrinking tumors. Participants receive both drugs by IV infusion over 42-day cycles.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- SKB264 (a drug given by IV) plus pembrolizumab (Keytruda, an immunotherapy drug)
- What this could lead to
- If it works, this combination could offer a new treatment option for several hard-to-treat cancers.
- What could go wrong
- This is an early-phase (Phase 2) study with only 240 people, so results may not apply to everyone. Side effects from the drug combination are possible and not yet fully known.
