About this study
Official title: An Open-label, Multicenter Phase 1/2 Study to Evaluate the Safety and Efficacy of AB-2100 in Patients With Recurrent Advanced or Metastatic Clear-cell Renal Cell Carcinoma (ccRCC)
This is a multi-center, open-label phase 1/2 trial evaluating the safety and efficacy of AB-2100 cell product. The study may enroll approximately 60 patients in phase 1 and approximately 70 patients in phase 2.
Read the detailed description
This study is intended for the patients who have been diagnosed with clear-cell renal cell carcinoma that either came back or did not improve after treatment with a checkpoint inhibitor and a VEGF inhibitor. The purpose of this study is to test the safety and efficacy of AB-2100 cells in patients with renal cell carcinoma. This treatment has not been approved by the Food and Drug Administration.
The goal of this study is to determine the maximum tolerated dose of the AB-2100 cells. T cells are part of the immune system that protect the body from infection and may help fight cancer. The T cells given in this study will come from the patient and will have a genetic circuit/logic gate put in them that makes them able to recognize prostate-specific membrane antigen (PSMA) and carbonic anhydrase 9 (CA9), 2 proteins found on tumor cells. These logic-gated T cells may help the body's immune system identify and kill cancer cells while sparing normal healthy tissues from toxicity.
The AB-2100 cells are given as a single intravenous infusion. Patients may be assigned to receive conditioning chemotherapy prior to the infusion
After completion of study treatment, patients are followed with serial measurements of safety, tolerability and response.
This is a research study to obtain new information that may help people in the future.

Also called Integrated Circuit T cells
autologous T cell therapy
| Study group | Role | What they receive |
|---|---|---|
| AB-2100 | Experimental | Patients receive a single dose of AB-2100 intravenously on day 0. Patients may be assigned to receive conditioning chemotherapy prior to the infusion. Receives: Biological: AB-2100 |
What is being measured
The primary outcome is the main question the study is designed to answer.
Phase 1 (Dose escalation): incidence of adverse events
Defined as dose-limiting toxicities based on a 3+3 dose escalation study design
Measured: From AB-2100 infusion up to 21 days post infusion
Phase 2 (Cohort expansion): Objective response rate (ORR)
ORR based on Independent Review Committee (IRC) assessment, defined as the proportion of subjects who have achieved a best overall response of CR or PR according to RECIST v1.1
Measured: From AB-2100 infusion up to 24 months post-infusion

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing AB-2100 in people with Advanced/Metastatic Clear Cell Renal Cell Carcinoma and Recurrence, run by Arsenal Biosciences, Inc. at 8 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: under way, not looking for participants, as of the sponsor's last update on 2 Nov 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 8 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Phase 1 (Dose escalation): incidence of adverse events (time frame: From AB-2100 infusion up to 21 days post infusion). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Nov 2026; AzTrials last refreshed its copy on 7 Nov 2026.
