What this trial studies

This clinical trial evaluates the safety and efficacy of AB-2100, an Integrated Circuit T cell therapy, in patients with recurrent clear-cell renal cell carcinoma (ccRCC) who have not responded to previous treatments. The study involves a multi-center approach, enrolling approximately 130 patients across two phases. Participants will receive genetically modified T cells that target specific proteins found on tumor cells, following a conditioning chemotherapy regimen. The primary goal is to determine the maximum tolerated dose of the therapy and its potential effectiveness in fighting cancer.

Who should consider this trial

Good fit: Ideal candidates are patients with advanced or metastatic clear-cell renal cell carcinoma who have previously received immune checkpoint inhibitors and VEGF-targeted therapies.

Not a fit: Patients who have not received prior systemic RCC therapy or those with recent systemic anti-cancer therapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this therapy could provide a new treatment option for patients with advanced kidney cancer who have limited alternatives.

How similar studies have performed: While this approach is innovative, similar studies using genetically modified T cells have shown promise in other cancers, suggesting potential for success.

Eligibility criteria

Inclusion Criteria:

* Advanced or metastatic clear-cell renal cell carcinoma
* Must have received an immune checkpoint inhibitor and a VEGF-targeted therapy in the advanced or metastatic setting. Must have evidence of progression on or after the last treatment regimen or discontinued treatment for unacceptable toxicity.
* Adequate organ function as per protocol definitions.
* Eastern Cooperative Oncology Group (ECOG) performance status score 0 or 1.
* Measurable disease at time of enrollment as per protocol definitions.
* Female subjects of childbearing potential and male subjects must agree to use acceptable method(s) of contraception from enrollment through at least 12 months after AB-2100 infusion.

Exclusion Criteria:

* Any prior systemic RCC therapy within 14 days of time of cell collection (interval of 28 days will be required if the last immediate treatment contained an antibody-based agent).
* Systemic anti-cancer therapy within 14 days of starting of conditioning chemotherapy (interval of 28 days will be required if the last immediate treatment contained an antibody-based agent)
* Investigational cellular therapies within 8 weeks prior to start of conditioning chemotherapy
* Prior treatment with anti-CA9 therapies
* Myocardial infarction or unstable angina within 6 months prior to screening
* Pleural effusion that requires drainage for symptom management within 28 days of screening.
* Active autoimmune disease requiring immunosuppressive therapy or uncontrolled with treatment.
* Untreated brain metastasis.
