Eligibility Criteria
- Ages
- 18 years to 65+ years (65+ Years, 18-64 Years)
- Accepts Healthy Volunteers
- Yes
Inclusion Criteria
- •Patients ≥ 18 years old
- •Pathologically confirmed and documented advanced and/or metastatic solid tumors with defined PRAME tumor target expression
- •Confirmed HLA status
- •Measurable disease according to Response Evaluation Criteria in Solid Tumors (RECIST 1.1)
- •Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 to 1
- •Patients must have received or not be eligible for all available indicated standard-of-care treatments
- •Adequate baseline hematologic, renal and hepatic function, acceptable coagulation status
Exclusion Criteria
- •Other active malignancies that require treatment or that might interfere with the trial endpoints
- •Patient is pregnant or is breastfeeding
- •History of hypersensitivity to components of IMA402, CPI treatment or rescue medications; contraindication for pembrolizumab
- •The patient has concurrent severe and/or uncontrolled medical disease. Any other health condition that would, in the investigator’s or sponsor’s judgement, contraindicate the patient’s participation in the clinical trial because of safety concerns or compliance with clinical trial procedures
- •Patients with active CNS metastases
