The study purpose is to establish the safety and tolerability of IMA201 in patients with
solid tumors that express melanoma-associated antigen 4 and/or 8 (MAGEA4/8).
SCREENING: Patient eligibility will be determined by HLA (human leukocyte antigen) screening
and the biomarkers screening. If the patient is eligible, white blood cells will be taken
during leukapheresis for the manufacture of the IMA201 product.
MANUFACTURING: IMA201 product will be made from the patient's white blood cells.
TREATMENT: Lymphodepletion with cyclophosphamide and fludarabine will occur in the days
before the IMA201 infusion to improve the duration of time that IMA201 stays in the body.
After IMA201 infusion, a low dose of IL-2 will be given twice daily for a period of time.
Patients will be closely monitored for safety and for a total of 3 years post IMA201
infusion.
Inclusion Criteria:
- Patient ≥ 18 years of age
- Pathologically confirmed advanced and/or metastatic solid tumor
- Patients may enter screening procedure before, during, or after the last available
indicated standard of care treatment. There is no limitation for prior anti cancer
treatments.
- Eastern Cooperative Oncology Group (ECOG) performance status 0-1
- HLA phenotype positive for the study
- Patients must have measurable disease according to RECIST 1.1
- Disease accessible to biopsy
- Adequate pulmonary function per protocol
- Adequate organ and bone marrow function per protocol
- Acceptable coagulation status per protocol
- Adequate hepatic function per protocol
- Adequate renal function per protocol
- Patient's tumor must express tumor antigen by qPCR using a fresh tumor biopsy specimen
- Life expectancy more than 3 months
- Confirmed availability of production capacities for IMA201 product
- Patients must have recurrent/progressing and/or refractory solid tumors and must have
received or not be eligible for all available indicated standard of care treatment.
- For hepatocellular carcinoma (HCC) patients only, Child-Pugh score of ≤ 6
- IMA201 product must have passed all of the release tests
- Female patient of childbearing potential must use adequate contraception prior to
study entry until 12 months after the infusion of IMA201
- Male patient must agree to use effective contraception or be abstinent while on study
and for 6 months after the infusion of IMA201
- The patient must have recovered from any side effects of prior therapy to Grade 1 or
lower (except for non-clinically significant toxicities; e.g., alopecia, vitiligo)
prior to lymphodepletion. As determined by the investigator, the patient may still be
eligible if the patient has not fully recovered from Grade ≥ 2 toxicities if these
toxicities are not anticipated to further improve (e.g., chronic neuropathy) and such
toxicities are not anticipated to worsen with the lymphodepletion therapy
Exclusion Criteria:
- History of other malignancies (except for adequately treated basal or squamous cell
carcinoma or carcinoma in situ) within the last 3 years
- Solid tumors with low likelihood of tumor biomarker expression per protocol
- 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 hypersensitivity to cyclophosphamide (CY), fludarabine (FLU), or IL-2, or
to any of the rescue medications
- History of or current immunodeficiency disease or prior treatment compromising immune
function at the discretion of the treating physician
- HIV infection, active hepatitis B virus (HBV), active hepatitis C virus (HCV)
infection, ongoing active anti-HCV treatment or detectable HBV or HCV viral load at
the most recent laboratory report. Patients with both HBV and HCV infections will be
excluded from screening
1. Patients with a history of HCV infection and with an undetectable viral load per
the most recent laboratory report and/or completed anti-HCV treatment but are HCV
antibody positive are permitted.
2. History of treated HBV infection is permitted if the viral load is undetectable
per the most recent laboratory report. Note: HCC patients with controlled HBV
infection, as defined by resolved (anti-hepatitis B surface antigen [HBs-Ag]
antibody (Ab) negative, anti-core antigen [HBc Ag] Ab positive) or chronic stable
(anti HBs-Ag Ab positive) HBV infection will be eligible for screening. Patients
with active HBV infection who are not on anti-HBV treatment will be excluded.
- Any condition contraindicating leukapheresis, lymphodepletion, low-dose IL-2, and/or
IMA201 treatment
- Patients with any active viral infection
- Patients with active brain metastases
NOTE: Patients with a history of brain metastases may be eligible, if an imaging scan with
contrast enhancement not older than 4 weeks is able to exclude the existence of currently
active brain metastasis, and steroid therapy has been discontinued for ≥2 weeks.
- Treatment with protocol-defined excluded treatments, medical devices, and/or
procedures per protocol
- Concurrent participation in an interventional part of another clinical trial
