Is this trial a fit for you?

Likely a good fit

Adults aged 18–75 with histologically or cytologically confirmed advanced solid tumors who can give informed consent and meet the study's health criteria.

Probably not a fit

Patients with uncontrolled serious internal diseases, severe cardiovascular conditions, recurrent or untreated effusions, or other exclusionary medical issues may not receive benefit from the study drug.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This single-arm, open-label Phase I investigator-initiated study tests WTX212A monotherapy (Cohort A) and WTX212A plus radiotherapy (Cohort B) in adults with advanced solid tumors. The trial includes an initial exploratory phase followed by an expansion phase to refine dosing and gather additional evidence of activity. Key outcomes are preliminary antitumor activity, safety, tolerability, immunogenicity, and pharmacokinetics. The study is run at the Cancer Center of Sun Yat-sen University in Guangzhou in collaboration with Westlake Therapeutics.

Why it matters

Potential benefit: If successful, WTX212A could offer a new treatment option that shrinks tumors or prolongs disease control, potentially more so when combined with radiotherapy.

How similar studies have gone: Combining systemic biologics or immunotherapies with radiotherapy has shown promising signals in early trials, but WTX212A's safety and activity in this setting remain preliminary and unproven.
