Study Endpoints

Primary Endpoints

Incidence of Dose-limiting Toxicities (DLTs)
The DLT observation period was from the time of chemotherapy until 30 days following the infusion of AFPc332T cells for each participant in all groups.

Number of participants experiencing at least one dose-limiting toxicity (DLT) following administration of autologous genetically modified AFPᶜ³³²T cells, assessed during the protocol-defined DLT evaluation period.

Number of Participants With Treatment-Emergent Adverse Events (TEAEs)
From first lymphodepleting chemotherapy through end of safety follow-up. Assessed at Days 9, 11, Weeks 2, 3, 4, 8, 12, 16, 24, then every 3 months until progression or withdrawal, up to approximately 4 years (data cut-off: 08 November 2022).

Number of participants experiencing at least one treatment-emergent adverse event (TEAE) following administration of lymphodepleting chemotherapy and autologous genetically modified AFPᶜ³³²T cells.

Number of Participants With Serious Adverse Events (SAEs)
From first lymphodepleting chemotherapy through end of safety follow-up. Assessed at Days 9, 11, Weeks 2, 3, 4, 8, 12, 16, 24, then every 3 months until progression or withdrawal, up to approximately 4 years (data cut-off: 08 November 2022).

Number of participants experiencing at least one serious adverse event (SAE) following administration of lymphodepleting chemotherapy and autologous genetically modified AFPᶜ³³²T cells

Secondary Endpoints

Overall Response Rate (ORR)
From first T-cell infusion; tumour assessments at Baseline, Weeks 4, 8, 16, 24, then every 3 months until disease progression or withdrawal, up to approximately 2 years (data cut-off: 08 November 2022).
Interval Between Date of First Documented Evidence of CR or PR Until First Documented Disease Progression or Death Due to Any Cause
From date of first confirmed CR or PR until disease progression or death due to any cause, assessed at Weeks 4, 8, 16, 24 and every 3 months thereafter, up to approximately 2 years (data cut-off: 08 November 2022).
Interval Between the Date of First Documented Evidence of SD Until First Documented Disease Progression or Death Due to Any Cause
From date of first documented SD until disease progression or death due to any cause, assessed at Weeks 4, 8, 16, 24 and every 3 months thereafter, up to approximately 2 years (data cut-off: 08 November 2022).

Frequently asked questions about ADP-A2AFP

What is ADP-A2AFP?

ADP-A2AFP is an investigational autologous genetically modified T-cell therapy developed by Adaptimmune Therapeutics for hepatocellular cancer and other AFP-expressing tumors. It is a gene therapy approach in which a patient's own T cells are engineered and then returned to the patient. It has been studied in a single Phase 1 trial.

What is ADP-A2AFP used for?

ADP-A2AFP has been studied for hepatocellular cancer and AFP-expressing tumors. The Phase 1 trial enrolled adults 18 years and older with advanced HCC. It is an investigational therapy and is not an approved treatment for hepatocellular cancer or any other indication.

Who is developing ADP-A2AFP?

ADP-A2AFP is developed by Adaptimmune Therapeutics PLC, which trades under the ticker ADAPY. The company sponsored the Phase 1 study of the therapy in advanced hepatocellular cancer and AFP-expressing tumors across the United States, France, Spain, and the United Kingdom.

What phase is ADP-A2AFP in?

ADP-A2AFP is in Phase 1 development. Its single clinical trial, NCT03132792, is a completed Phase 1 study that enrolled 39 patients. ADP-A2AFP is investigational and has not been approved by the FDA for any indication.

What clinical trials is ADP-A2AFP in?

ADP-A2AFP has been evaluated in one clinical trial, NCT03132792, titled AFPᶜ³³²T in Advanced HCC. The completed Phase 1 study enrolled 39 patients with hepatocellular cancer or AFP-expressing tumors in the United States, France, Spain, and the United Kingdom. It was an uncontrolled study open to all sexes.

Is ADP-A2AFP the same as autologous genetically modified AFPᶜ³³²T cells?

Yes. ADP-A2AFP is also known as autologous genetically modified AFPᶜ³³²T cells. Both names refer to the same Adaptimmune Therapeutics T-cell therapy studied in the Phase 1 trial NCT03132792 in advanced hepatocellular cancer and AFP-expressing tumors.
