New drug combo targets stomach cancer protein in 100-Patient trial
NCT ID NCT06962137
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether adding the targeted drug zolbetuximab to standard chemotherapy (paclitaxel and ramucirumab) can help people with advanced stomach or gastroesophageal cancer live longer. It includes 100 adults whose tumors have a specific protein called CLDN18.2. Participants receive the drug combination as a second treatment after first-line therapy has stopped working.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- zolbetuximab (a targeted antibody) plus paclitaxel and ramucirumab (chemotherapy drugs)
- What this could lead to
- If it works, this could offer a more effective second-line treatment option for people with a specific type of stomach cancer.
- What could go wrong
- This is a Phase 2 trial with only 100 participants, so results are preliminary. The added drug may cause more side effects and might not improve survival compared to standard care.
