Conditions

  • Metastatic Castration-Resistant Prostate Cancer

The primary objective of the study is to determine the efficacy of [Lu-177]-PNT2002 ([Lu-177]-PSMA-I&T) versus abiraterone or enzalutamide in delaying radiographic progression in patients with mCRPC.

The study consists of 3 phases: Dosimetry, Randomized Treatment, and Long term Follow up.

The study will commence with a 25-patient safety and dosimetry lead-in (Part 1) and proceed to a randomization treatment phase in approximately 390 patients (Part 2). Patients in Part 2 will be randomized in a 2:1 ratio to receive either [Lu-177]-PNT2002 (Arm A), or enzalutamide or abiraterone (Arm B). Patients in Arm B who experience radiographic progression per central review and meet protocol defined eligibility, may crossover to receive [Lu-177]-PNT2002. All patients will be followed in long-term follow-up for at least 5 years from the first therapeutic dose, death, or loss to follow up (Part 3).

Only patients that meet PSMA PET avidity criteria per central review will be eligible for this study.

Local PI Neil Fleshner

Conditions:

  • Metastatic Prostate Cancer
  • Castration-resistant Prostate Cancer
  • Prostatic Neoplasm
  • Cancer of the Prostate
  • Progressive mCRPC

This is a multicenter, randomized, controlled, phase 2 clinical trial designed to evaluate the safety and efficacy of I-131-1095 radiotherapy in combination with enzalutamide compared to enzalutamide alone in participants with prostate-specific membrane antigen (PSMA)-avid metastatic castration resistant prostate cancer (mCRPC) who have progressed on abiraterone. Participants must be chemotherapy-naive and must be ineligible or refuse to receive taxane-based chemotherapy at time of study entry. PSMA-avidity will be determined by central imaging review based on assessment of 18F-DCFPyL PET/CT imaging during screening. Eligible participants meeting the PSMA-avidity criteria will be randomized in a 2:1 ratio to receive either I-131-1095 in combination with enzalutamide (80 participants) or enzalutamide alone (40 participants). An interim analysis for efficacy will be performed after a minimum of 48 evaluable participants have PSA data for at least three months following the first dose of randomized treatment.

All participants will be followed for efficacy, safety assessments, survival status, adverse events of special interest, and new anti-cancer therapy for at least one year or to the end of the study (whichever is later) following the first dose of randomized treatment. Safety data will be monitored by an independent Data Monitoring Committee and the sponsor.

177 LuPSMA-617 vs Docetaxel in Metastatic Castration Resistant and PSMA-Positive Prostate Cancer

ClinicalTrials.gov ID NCT04663997
Sponsor Canadian Cancer Trials Group
Local PI Aaron Hansen & Di Maria Jiang

Conditions:

  • Prostate Cancer

The standard or usual treatment for this disease is a chemotherapy drug called docetaxel, given by intravenous every 3 weeks, for up to 12 treatments.

177Lu-PSMA-617 is a new type of therapy for prostate cancer. Laboratory tests show that it may help slow the growth of prostate cancer. 177Lu-PSMA-617 has been shown to shrink tumours in animals and has been studied in limited numbers of men with prostate cancer and seems promising but it is not clear if it can offer better control of prostate cancer compared to docetaxel chemotherapy .
