Study Endpoints

Primary Endpoints

1. Incidence of participants with dose-limiting toxicities (DLTs), adverse events (AEs), including adverse events of special interest (AESI) and serious adverse events (SAEs). Determination of the recommended dose of AZD5851 for expansion phase
Through study completion, an average of 2 years

Determine if treatment with AZD5851 is safe and tolerable through assessment of DLTs, AEs, SAEs and changes from baseline in vital signs, ECGs, and laboratory parameters

Secondary Endpoints

1. Proportion of participants with a confirmed Complete Response (CR) or Partial Response (PR)
Through study completion, an average of 2 years
2. Interval between the date of AZD5851 infusion dose and first documented evidence of CR or PR
Through study completion, an average of 2 years
3. Proportion of participants who have a confirmed CR, PR, or who have stable disease (SD) for at least 5 weeks after the date of AZD5851 infusion
Through study completion, an average of 2 years

AZD5851EXPERIMENTALSubjects will receive AZD5851 following 3 consecutive doses of lymphodepleting chemotherapy (fludarabine and cyclophosphamide).

Interventions

NameTypeDescription
AZD5851BIOLOGICALSubjects will undergo leukapheresis to isolate peripheral blood mononuclear cells (PBMCs) to produce AZD5851. During AZD5851 production, subjects may receive bridging therapy for disease control. Upon successful generation of AZD5851 product, subjects will receive treatment with AZD5851 therapy. Study treatment will include lymphodepleting chemotherapy followed by one dose of AZD5851 administered by intravenous (IV) infusion.

Frequently asked questions about AZD5851

What is AZD5851 used for in hepatocellular carcinoma?

AZD5851 is an investigational monoclonal antibody being developed for the treatment of GPC3-positive advanced or recurrent hepatocellular carcinoma, a type of liver cancer. It is currently in Phase 1 clinical development and has not been approved by regulatory authorities.

What does AZD5851 target?

AZD5851 targets GPC3, a protein that is overexpressed in hepatocellular carcinoma cells. By binding to GPC3, the monoclonal antibody is designed to direct the immune system to attack and destroy cancer cells that express this protein.

Who is developing AZD5851?

AZD5851 is being developed by AstraZeneca PLC, a global biopharmaceutical company listed on the NASDAQ under the ticker symbol AZN. The company is conducting clinical trials to evaluate the safety and efficacy of this investigational therapy.

What phase is AZD5851 in?

AZD5851 is currently in Phase 1 clinical development. It is an investigational drug, meaning it has not been approved by the FDA or other regulatory agencies and is still being studied in clinical trials to assess its safety and effectiveness.

What clinical trials is AZD5851 in?

AZD5851 is being evaluated in a Phase I/II study (NCT06084884) for GPC3-positive advanced or recurrent hepatocellular carcinoma. This active, non-recruiting trial has an enrollment of 94 participants and is being conducted in the United States, Japan, and South Korea.
