Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 18 and older with advanced solid tumors expressing Claudin18.2 and a life expectancy of at least 12 weeks.
✕Probably not a fit
Patients with tumors that do not express Claudin18.2 or those with significant comorbidities may not benefit from this study.

What this trial studies
This clinical trial evaluates the safety, tolerability, and efficacy of AZD0901, both as a standalone treatment and in combination with other chemotherapy agents, for patients with advanced solid tumors that express the protein Claudin18.2. The study includes multiple sub-studies focusing on different types of cancers, including gastric, gastroesophageal junction, biliary tract, and pancreatic cancers. Participants will receive AZD0901 via intravenous infusion, and the study will assess various outcomes including pharmacokinetics and immunogenicity.
Why it matters
Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with advanced cancers expressing Claudin18.2.
How similar studies have gone: Other studies targeting Claudin18.2 have shown promise, indicating potential for success with this approach.
