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).

Condition or Disease Intervention/Treatment Phase
  • Biological: IMA203 Product
  • Biological: IMA203CD8 Product
  • Device: IMADetect®
  • Drug: nivolumab (Opdivo®)
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.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Dose Escalation

Dose escalation of IMA203

Biological: IMA203 Product
The cell dose will be based on viable CD3+CD8+ HLA-Dextramer+ cells per body surface area (BSA) as defined by the Mosteller formula.

Device: IMADetect®
IMADetect® is developed as a companion diagnostic to aid in selecting patients with relapsed and/or refractory solid cancers who might be eligible for enrollment in Immatics clinical trials. IMADetect® is intended for investigational use only.

Experimental: Extension Cohort A

Experimental: Extension Cohort B

IMA203 at RP2D + nivolumab

Biological: IMA203 Product
The cell dose will be based on viable CD3+CD8+ HLA-Dextramer+ cells per body surface area (BSA) as defined by the Mosteller formula.

Device: IMADetect®
IMADetect® is developed as a companion diagnostic to aid in selecting patients with relapsed and/or refractory solid cancers who might be eligible for enrollment in Immatics clinical trials. IMADetect® is intended for investigational use only.

Drug: nivolumab (Opdivo®)
Nivolumab will be given post IMA203 infusion, after hematologic recovery is achieved. Clinical supply provided by Bristol Myers Squibb.
