ACTengine® IMA203/IMA203CD8 as Monotherapy or in Combination With Nivolumab in Recurrent and/or Refractory Solid Tumors
Study Details
Study Description
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).

Phase 1 |
Detailed Description
SCREENING: Patient eligibility will be determined by protocol inclusion/exclusion criteria including HLA (human leukocyte antigen) screening and a biopsy 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 and 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, a low dose of IL-2 will be given subcutaneously daily for 10 days.
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.
