Study Endpoints

Primary Endpoints

Undetectable prostate specific antigen (PSA) rate at 12 months after commencement of protocol therapy
Upto 32 months assuming 18 months to complete recruitment, a maximum of 1.6 months from consent to commencement of treatment for last patient and then 12 months from commencement of treatment for last patient.

Undetectable PSA is defined as PSA ≤ 0.2ng/ml at 12 months after protocol treatment commencement. Patients who experience unequivocal radiographic (by conventional imaging modality) and/or clinical disease progression within 12 months of initiating protocol treatment will be considered as not having undetectable PSA at 12 months.

Secondary Endpoints

Safety of 177Lu-PSMA followed by docetaxel compared to docetaxel alone
Through completion of treatment, maximum 26 months.
Time to development of castration resistance between treatment Arms
Through study completion, up until 2 years after the last patient commences treatment.
PSA-progression free survival (PSA-PFS) between treatment Arms
Through study completion, up until 2 years after the last patient commences treatment.

Frequently asked questions about 177Lu-PSMA-617

What is 177Lu-PSMA-617 used for in Metastatic Hormone Naive Prostate Cancer?

177Lu-PSMA-617 is an investigational small molecule being studied for the treatment of Metastatic Hormone Naive Prostate Cancer. It is a radionuclide therapy that delivers radiation to prostate-specific membrane antigen (PSMA) expressing cells. The drug is currently in Phase 2 clinical development and is not yet approved by regulatory authorities.

What does 177Lu-PSMA-617 target?

177Lu-PSMA-617 targets prostate-specific membrane antigen (PSMA), a protein highly expressed on prostate cancer cells. By binding to PSMA, the drug delivers a radioactive payload (Lutetium-177) directly to the tumor cells, potentially causing cell death while sparing normal tissues. This targeted approach is being evaluated in metastatic hormone naive prostate cancer.

Who is developing 177Lu-PSMA-617?

177Lu-PSMA-617 is being developed by Pulmonx Corporation, a company traded on the NASDAQ under the ticker symbol LUNG. The company is conducting a Phase 2 clinical trial to evaluate the safety and benefit of this radionuclide treatment in men with metastatic prostate cancer.

What phase is 177Lu-PSMA-617 in?

177Lu-PSMA-617 is currently in Phase 2 clinical development. It is an investigational drug, meaning it has not been approved by the FDA or other regulatory agencies. The ongoing Phase 2 trial is active but not recruiting participants, and it is designed to assess the safety and efficacy of the treatment in metastatic hormone naive prostate cancer.

What clinical trials is 177Lu-PSMA-617 in?

177Lu-PSMA-617 is being studied in one active Phase 2 clinical trial with the identifier NCT04343885. The trial, titled 'In Men With Metastatic Prostate Cancer, What is the Safety and Benefit of Lutetium-177 PSMA Radionuclide Treatment in Addition to Chemotherapy,' is enrolling 130 male participants aged 18 years and older in Australia. The study is randomized and controlled, but not double-blinded.
