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.

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.

Suffering from other serious internal diseases, including but not limited to: uncontrolled diabetes, active peptic ulcer, liver cirrhosis, active bleeding, etc., those with uncontrollable or severe cardiovascular diseases, such as NYHA Class II or higher congestive heart failure, unstable angina, myocardial infarction, etc., within 6 months before the first dose, difficult to control hypertension (systolic blood pressure ≥180mmHg and/or diastolic blood pressure ≥100mmHg). 2. Uncontrollable pleural effusion, peritoneal effusion, or pericardial effusion requiring puncture and drainage, or recurrence requiring re-drainage after puncture and drainage. 3. History of pulmonary fibrosis, interstitial pneumonia, pneumoconiosis, radiation pneumonitis, drug-related pneumonia, or severe lung function impairment. 4. Previous IO drug treatment with adverse events related to the drug that required permanent discontinuation of IO treatment.
