Is this trial a fit for you?
✓Likely a good fit
Adults (18+) with advanced NSCLC, pancreatic, gastric/GEJ, or esophageal cancer who have had at least one prior therapy and whose disease progressed or recurred.
✕Probably not a fit
Patients whose cancer does not respond to the study drug or who cannot tolerate its side effects may not benefit.

What this trial studies
This Phase 1 trial evaluates the safety and how PF-08098488 behaves in the body of adults with advanced solid tumors including NSCLC, pancreatic, gastric, GEJ, and esophageal cancers. Participants receive PF-08098488 by IV infusion and are monitored for side effects and signals of helpful activity. The study also looks at how the drug moves through and is processed by the body, to guide future research. Enrollment requires measurable disease, prior therapy, and good performance status.
Why it matters
Potential benefit: If successful, participants may experience disease stabilization or tumor shrinkage and gain medical knowledge that could support future cancer treatments.
How similar studies have gone: Prior early-phase studies in other cancers have shown safety signals; whether PF-08098488 will be beneficial remains to be determined.
