A Safety And Efficacy Study Of HLA-G- Targeted CAR-T Cells IVS-3001 In Subjects With Previously Treated Advanced HLA-G-Positive Solid Tumors
United States31 participantsStarted 2023-06-21
Plain-language summary
The proposed clinical study is a Phase 1/2a trial to investigate the safety, tolerability, pharmacokinetics and clinical activity of anti-HLA-G CAR-T cells IVS-3001 administered to subjects with previously treated, locally advanced, or metastatic solid tumors which are HLA-G positive (HLA-G+) - as determined by immunohistochemistry (IHC) analysis on tumor biopsies using the 4H84 antibody.

Inclusion criteria
. Age ≥18 years old.
. Histologically or pathologically confirmed diagnosis of a locally advanced unresectable or metastatic HLA-G+ select solid tumor malignancy who failed or intolerant to standard of care therapies known to confer clinical benefit per treating physician.
. Cohort 1: HLA-G+ clear cell renal cell carcinoma who failed or intolerant to checkpoint inhibitor (CPI) and tyrosine kinase inhibitor (TKI)
. Cohort 2: Epithelial ovarian carcinoma who failed or intolerant to platinum-based therapy, and should have failed or intolerant for PARP inhibitor if BRCA 1/2 mutated
. Cohort 3: Other HLA-G+ tumors (biomarker driven) who failed or intolerant to at least one prior line of therapy and for whom at discretion of treating physician there is no standard therapy to confer a clinical benefit
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Incidence of Adverse Events, Graded According to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) Version (v) 5.0
Timeframe: through study completion an average of 3 years.
2
. Objective Response Rate (ORR) according to Response Evaluation Criteria in Solid Tumors (RECIST) 1.1
Timeframe: through study completion an average of 3 years
. HLA-G expression on tumor cells (any level of expression is acceptable) as determined by immunohistochemistry (IHC) analysis on tumor biopsies using the 4H84 antibody \[1, 2\]
. Measurable disease (at least one target lesion) per RECIST v1.1 \[3\]
. Life expectancy \>12 weeks.
Exclusion criteria
. Immunotherapy at enrollment and after. Note: Bridging therapies (including herbal therapies) other than immunotherapies are allowed from cell harvest to 2 weeks before lymphodepletion (5 weeks for nitrosoureas or mitomycin) or 5 half-lives, whichever is shorter and must be reported in the CRF.
. Symptomatic, untreated, or actively progressing central nervous system metastases (subjects with prior brain metastases treated at least 2 weeks prior to the planned IVS-3001 infusion who are clinically stable and do not require chronic corticosteroid treatment are allowed.
. Primary CNS tumors.
. History or presence of clinically relevant CNS pathology such as epilepsy, seizure, paresis, aphasia, stroke, severe brain injuries, dementia, Parkinson's disease, cerebellar disease, organic brain syndrome, psychosis, or leptomeningeal disease.
. Ongoing toxicities related to prior anticancer therapy that have not resolved to Grade ≤ 1 (other than alopecia). Note: Current unresolved Grade ≥ 2 non-hematologic toxicity may be allowed after discussing with the study Chair/Co-Chair.
. Participation in any investigational drug study within 4 weeks prior to cell infusion.
. Autoimmune disease, chronic infection or any disease requiring systemic immunosuppressive therapy (e.g., calcineurin inhibitors, methotrexate, immunosuppressive antibodies such as anti-IL-6 or anti-IL-6-receptor).
. Prior CAR T cell or other genetically modified T cell therapy.
