A Study to Evaluate the Safety and Efficacy of A2B395, an Allogeneic Logic-gated CAR T, in Participants With Solid Tumors That Express EGFR and Have Lost HLA-A*02 Expression
United States240 participantsStarted 2025-05-22
Plain-language summary
The goal of this study is to test A2B395, an allogeneic logic-gated Tmod™ CAR T-cell product in subjects with solid tumors including colorectal cancer (CRC), non-small cell lung cancer (NSCLC), head and neck squamous cell carcinoma (HNSCC), triple-negative breast cancer (TNBC), renal cell carcinoma (RCC) and other solid tumors that express EGFR and have lost HLA-A\*02 expression.
The main questions this study aims to answer are:
* Phase 1: What is the recommended dose of A2B395 that is safe for patients
* Phase 2: Does the recommended dose of A2B395 kill the solid tumor cells and protect the patient's healthy cells
Participants will be required to perform study procedures and assessments, and will also receive the following study treatments:
* Enrollment in BASECAMP-1 (NCT04981119)
* Preconditioning lymphodepletion (PCLD) regimen
* A2B395 Tmod CAR T cells at the assigned dose

Inclusion criteria
. Appropriately enrolled in the BASECAMP-1 A2 Biotherapeutics, Inc. study, with tissue demonstrating LOH of HLA-A\*02 by NGS (whenever possible from the primary site).
. Histologically confirmed recurrent unresectable, locally advanced, or metastatic CRC, NSCLC, HNSCC, TNBC, RCC, or other solid tumors with EGFR expression. Measurable disease is required with lesions of ≥1.0 cm by CT.
. Received previous required therapy for the appropriate solid tumor disease as described in the protocol
. Has adequate organ function as described in the protocol
. ECOG performance status of 0 to 1
. Life expectancy of ≥3 months
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
Phase 1: Rate of adverse events and dose limiting toxicities (DLTs) by dose level
Timeframe: From the time of Informed consent until 24 months (2 years) post A2B395 infusion
2
Phase 1: Recommended phase 2 dose (RP2D)
Timeframe: 28 days post A2B395 infusion
3
Phase 2: The overall response rate (ORR) for patients
. Willing to comply with study schedule of assessments including long-term safety follow-up
Exclusion criteria
. Has disease that is suitable for local therapy or able to receive standard of care therapy that is therapeutic and not palliative
. Prior allogeneic stem cell transplant
. Prior solid organ transplant
. Cancer therapy within 3 weeks or 3 half lives of A2B395 infusion
. Radiotherapy within 28 days of A2B395 infusion
. Unstable angina, arrhythmia, myocardial infarction, or any other significant cardiac disease within the last 6 months
. Any new symptomatic pulmonary embolism (PE) or a deep vein thrombosis (DVT) within 3 months of enrollment. Therapeutic dosing of anticoagulants is allowed for history of PE or DVT if greater than 3 months from time of enrollment, and adequately treated
. History of interstitial lung disease including drug-induced interstitial lung disease and radiation pneumonitis that requires treatment with prolonged steroids or other immune suppressive agents within 1 year
