Study Arms (1)
Rollover subjects from Alaunos Therapeutics TCR-T cell drug product interventional studies
This is a rollover protocol designed to provide long-term follow-up to all subjects previously enrolled in any Alaunos Therapeutics autologous, neoantigen specific TCR-T cell drug product interventional studies. Patients will be followed for up to 15 years after dosing of Alaunos Therapeutics autologous, neoantigen specific TCR-T cell drug product.
Interventions
No study drug is administered in this study. Patients who have received Neoantigen specific TCR-T cell drug product will be evaluated in this trial for long-term safety and efficacy
Eligibility Criteria
Patients will be enrolled following either the completion or early termination/discontinuation from Study NCT05194735 or any protocol in which patients were administered Neoantigen specific TCR-T cell drug product. Patients will begin the long-term follow-up period regardless of whether they responded to treatment or progressed on treatment. Patients will be followed for up to 15 years post TCR-T cell drug product infusion and will continue to be monitored for safety, immunogenicity and efficacy.
You may qualify if:
- Subjects treated with TCR-T cell drug product on study TCR001-201 or any other Alaunos TCR-T cell drug product study and have either completed their original treatment protocol or have discontinued early.
- Subject is willing and able to adhere to the study visit schedule and other protocol requirements.
- Subject must be capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol.
- Subjects agree to allow clinical samples to be collected and stored at study site and/or Alaunos Therapeutics, Inc. (Alaunos) or designee for testing.

Biospecimen
Peripheral blood samples will be collected for the analysis of TCR-T cell drug product persistence by vector copy number (VCN). The collection of tumor tissue samples is to enable the investigation of changes that may occur within the tumor associated with progression. Tissue samples will be analyzed by NGS (e.g., WES, RNA-Seq, etc.) to evaluate T cell infiltration, TCR-T cell drug product infiltration, presence of HLA alleles and presence of tumor-specific neoantigens. Additional confirmatory analyses of these samples (e.g., immunohistochemistry (IHC) or in situ hybridization (ISH)to verify target expression) may be performed based on emergent data and sufficient sample availability.
