Brief Summary

The study purpose is to establish the safety and tolerability of IMA203/IMA203CD8 products with or without combination with nivolumab in patients with solid tumors that express preferentially expressed antigen in melanoma (PRAME).

Detailed Description

SCREENING: Patient eligibility will be determined by protocol inclusion/exclusion criteria including HLA (human leukocyte antigen) screening and a biopsy (or collection of archival tumor tissue) for biomarker screening. If the patient is eligible, white blood cells will be taken during leukapheresis for the manufacture of an IMA203 or an IMA203CD8 product.

MANUFACTURING: IMA203 or IMA203CD8 products will be made from the patients' white blood cells.

TREATMENT: Lymphodepletion with cyclophosphamide and fludarabine will occur in the days before the IMA203/IMA203CD8 product infusion to improve the duration of time that IMA203/IMA203CD8 product stays in the body. The patient will be admitted to the hospital during the T-cell infusion.

After the IMA203/IMA203CD8 product infusion, if applicable, a low dose of IL-2 will be given subcutaneously until day 10.

In Extension Cohort B (IMA203) nivolumab will be administered intravenously.

Patients will be monitored closely throughout the study. The follow-up phase ends 5 years post infusion.

Exclusion Criteria
  • History of other malignancies (except for adequately treated basal or squamous cell carcinoma or carcinoma in situ) within the last 3 years
  • Pregnant or breastfeeding
  • Serious autoimmune disease Note: At the discretion of the investigator, these patients may be included if their disease is well controlled without the use of immunosuppressive agents.
  • History of cardiac conditions as per protocol
  • Prior stem cell transplantation or solid organ transplantation
  • Concurrent severe and/or uncontrolled medical disease that could compromise participation in the study
  • History of or current immunodeficiency disease or prior treatment compromising immune function at the discretion of the treating physician

  • Patients with active brain metastases
  • Concurrent treatment in another clinical trial.
  • For nivolumab treatment, patients must not have a history of severe immune-related toxicities, defined as any Grade 3 or 4 toxicities related to prior PD1/PD-L1 inhibitor therapy (e.g., atezolizumab, pembrolizumab or nivolumab etc.).

Other protocol defined inclusion/exclusion criteria could apply
