Who this trial is looking for
This trial is looking for adults with specific types of cancer that have certain markers, such as colorectal cancer and lung cancer. Participants will receive a treatment called A2B395 and will undergo specific medical assessments throughout the study.
Are You a Good Fit for This Trial?
You may be able to join if
I have been diagnosed with a solid tumor that expresses EGFR.
I have measurable cancer that has come back or spread.
I have received the required treatment for my cancer before.
I have good organ function.
I am able to participate in the study assessments.
I expect to live for at least 3 more months.
I have an ECOG performance status of 0 or 1.
You may not be able to join if
I have cancer that can be treated with standard local therapy.
I have had an allogeneic stem cell transplant.
I have had a solid organ transplant.
I have received cancer therapy within the last 3 weeks.
I have had radiotherapy within 28 days of the treatment.
I have serious heart problems within the last 6 months.
I need supplemental home oxygen.
I am pregnant or breastfeeding.

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 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

2. 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.
3. Received previous required therapy for the appropriate solid tumor disease as described in the protocol
4. Has adequate organ function as described in the protocol
5. ECOG performance status of 0 to 1
6. Life expectancy of ≥3 months
7. Willing to comply with study schedule of assessments including long-term safety follow-up
Key Exclusion Criteria:
1. Has disease that is suitable for local therapy or able to receive standard of care therapy that is therapeutic and not palliative
2. Prior allogeneic stem cell transplant
3. Prior solid organ transplant
4. Cancer therapy within 3 weeks or 3 half lives of A2B395 infusion
5. Radiotherapy within 28 days of A2B395 infusion
6. Unstable angina, arrhythmia, myocardial infarction, or any other significant cardiac disease within the last 6 months
7. 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
8. 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
9. Requires supplemental home oxygen
10. Females of childbearing potential who are pregnant or breastfeeding
11. Subjects, both male and female, of childbearing potential who are not willing to practice birth control from the time of consent through 6 months post infusion of A2B395
