This study is an expanded access protocol for AMTAGVI that has not yet been released for commercial use.

Making the AMTAGVI product involves collecting immune cells from your cancer, growing more of them in the laboratory, and giving them back to you to treat your cancer. AMTAGVI is a commercially available treatment approved by the FDA (US Food and Drug Administration) for advanced melanoma. However, sometimes during the manufacturing of AMTAGVI, the final product is Out of Specification (OOS). This means that the test results for your product do not meet the accepted established criteria. The purpose of this study is to allow expanded access use of out of specification (OOS) AMATAGVI.

Expanded access is a potential pathway for a patient with an immediately life-threatening condition or serious disease or condition to gain access to an investigational medical product for treatment outside of clinical trials when no comparable or satisfactory alternative therapy options are available. While this use involves an investigational product, this is not a research study.

Risks include vitiligo, swelling of the middle layer of the eye (uveitis), shortness of breath, and increased heart rate. There will be approximately 8-10 study visits over a 24-month period. Visit durations will vary. Patients may or may not benefit from receiving OOS AMTAGVI when compared to receiving no treatment at all.
