Study Endpoints

Primary Endpoints

Number of participants with adverse events (AE), adverse events of special interest (AESI), and serious adverse events (SAE)
From time of Informed Consent to 90 days post last dose of study intervention (up to 3 years)

Number of participants with AEs, AESIs, SAEs, including AEs leading to discontinuation of study intervention and clinically significant alterations from baseline in laboratory parameters, vital signs, ECGs and physical examination results

Number of participants with dose-limiting toxicity (DLT), as defined in the protocol (Part A only)
From first study dose to 21 OR 28 days post first dose based on schedule

A DLT is a toxicity defined by the study protocol that occurs from the first dose of study intervention up to the end of the DLT evaluation period that is assessed as clearly unrelated to the primary disease or intercurrent illness

PSA response rate (Part B only)
Up to 3 years

Number of participants with a PSA50 response

Frequently asked questions about AZD8359

What is AZD8359 used for in metastatic prostate cancer?

AZD8359 is an investigational small molecule being studied for the treatment of metastatic prostate cancer. It is currently in Phase 1 clinical development, with a first-in-human trial evaluating its safety and efficacy in participants with this condition.

What does AZD8359 target?

AZD8359 is a STEAP2 T-cell engager (TCE), meaning it is designed to target the STEAP2 protein, which is expressed on prostate cancer cells, and engage T-cells to attack those cells. This mechanism is being evaluated in the ongoing Phase 1 trial.

Who makes AZD8359?

AZD8359 is being developed by AstraZeneca PLC, a biopharmaceutical company listed on the stock exchange under the ticker symbol AZN. The company is conducting a Phase 1 clinical trial for this drug in metastatic prostate cancer.

What phase is AZD8359 in?

AZD8359 is in Phase 1 clinical development. It is an investigational drug, not yet approved by regulatory authorities, and is currently being studied in a first-in-human trial for metastatic prostate cancer.

What clinical trials is AZD8359 in?

AZD8359 is being evaluated in a Phase 1 clinical trial with the identifier NCT07529717, titled 'First-in-Human Study to Evaluate AZD8359 STEAP2 TCE in Participants With Prostate Cancer.' This trial is currently recruiting participants with metastatic prostate cancer in the United States, Australia, and South Korea.

Is AZD8359 the same as a STEAP2 T-cell engager?

Yes, AZD8359 is a STEAP2 T-cell engager (TCE), a type of small molecule designed to link T-cells to STEAP2-expressing prostate cancer cells. This mechanism is the focus of its ongoing Phase 1 clinical trial in metastatic prostate cancer.
