Clinical Trials for Prostate Cancer

Prospective Evaluation of Pencil Beam Scanning Proton Therapy for Previously Irradiated Tumors

Moderate burden on patient

The trial has a moderate burden on patients. An example would be a trial testing an IV drug, with scans every 8 weeks which would be more frequent than standard of care.

Started >3 years ago

The trial was activated more than 3 years ago. This is not always bad but can indicate that the trial has less current treatments, or has had trouble getting enough patients to enroll due to other issues.

TrialFetch AI summary: This trial enrolls adults with recurrent or second primary tumors in body sites previously treated with radiotherapy—including CNS, head and neck, breast, thoracic, GI, GU, and gynecological cancers—to evaluate reirradiation using pencil beam scanning proton therapy, which aims to provide effective tumor control with reduced toxicity compared to standard photon techniques. No investigational drugs are included, and some cohorts may not allow concurrent chemotherapy.

A Pharmacodynamics-Driven Trial of Talazoparib, an Oral PARP Inhibitor, in Patients With Advanced Solid Tumors and Aberrations in Genes Involved in DNA Damage Response

Moderate burden on patient

The trial has a moderate burden on patients. An example would be a trial testing an IV drug, with scans every 8 weeks which would be more frequent than standard of care.

Started >3 years ago

The trial was activated more than 3 years ago. This is not always bad but can indicate that the trial has less current treatments, or has had trouble getting enough patients to enroll due to other issues.

TrialFetch AI summary: This trial enrolls adults with advanced or metastatic solid tumors harboring deleterious germline or somatic DNA damage response (DDR) gene aberrations who have progressed after standard therapy, including those with prior platinum or PARP inhibitor exposure. Patients receive oral talazoparib, a PARP1/2 inhibitor that exploits defective DNA repair in cancer cells, administered daily in 28-day cycles until disease progression or unacceptable toxicity.

TrialFetch AI summary: This trial enrolls adults with previously treated, castration-sensitive oligometastatic prostate adenocarcinoma (1-5 PET-detected bone or nodal/soft tissue metastases, including at least one extrapelvic), randomizing them to stereotactic ablative body radiation therapy (SABR) plus either relugolix (an oral GnRH receptor antagonist) or placebo for 6 months.

ClinicalTrials.gov ID: NCT05053152

Bipolar Androgen Therapy (BAT) and Radium-223 (RAD) in Metastatic Castration-resistant Prostate Cancer (mCRPC) (BAT-RAD Study)

Moderate burden on patient

The trial has a moderate burden on patients. An example would be a trial testing an IV drug, with scans every 8 weeks which would be more frequent than standard of care.

Started >3 years ago

The trial was activated more than 3 years ago. This is not always bad but can indicate that the trial has less current treatments, or has had trouble getting enough patients to enroll due to other issues.

TrialFetch AI summary: Men with mCRPC with bone-predominant disease, asymptomatic/minimally symptomatic, castrate testosterone, prior exposure to ≤1 novel AR-targeted agent (and no visceral metastases) receive radium-223 plus Bipolar Androgen Therapy (testosterone cypionate). Radium-223 is an alpha-emitting bone-targeted radiopharmaceutical, and BAT cycles supraphysiologic testosterone to induce DNA damage and potentially re-sensitize AR signaling.

ClinicalTrials.gov ID: NCT04704505

LuCarbo - a Phase 1a/1b Study of 177Lu-PSMA-617 Plus Carboplatin in Metastatic Castrate-resistant Prostate Cancer

High burden on patient

The trial has a high burden on patients. An example would be a phase 1 trial with extra tumor biopsies and frequent pharmacokinetic blood draws.

TrialFetch AI summary: Adults with progressive mCRPC post–ARPI and taxane, ECOG 0–2, PSMA-avid on 68Ga-PSMA PET, receive 177Lu-PSMA-617 radioligand therapy (targets PSMA to deliver beta radiation) combined with carboplatin DNA–crosslinking chemotherapy; prior PARPi/Ra-223 allowed, prior 177Lu-PSMA-617 excluded. Single-arm dose-escalation/expansion evaluates safety and preliminary efficacy, with carboplatin Days 1/22 and 177Lu-PSMA-617 Day 2 every 6 weeks for up to 6 cycles.

A Phase II Randomized Study of Sipuleucel-T With or Without Continuing New Hormonal Agents (NHA) in Metastatic Prostate Cancer With PSA Progression While on NHA and LHRH Analog

Moderate burden on patient

The trial has a moderate burden on patients. An example would be a trial testing an IV drug, with scans every 8 weeks which would be more frequent than standard of care.

Started >3 years ago

The trial was activated more than 3 years ago. This is not always bad but can indicate that the trial has less current treatments, or has had trouble getting enough patients to enroll due to other issues.

TrialFetch AI summary: Asymptomatic or minimally symptomatic mCRPC patients with PSA-only progression on continuous ADT plus a new hormonal agent (abiraterone, enzalutamide, or apalutamide) and no visceral disease are randomized to receive sipuleucel‑T with the NHA continued versus stopped. Sipuleucel‑T is an autologous cellular immunotherapy activating APCs ex vivo with a PAP–GM‑CSF fusion protein; NHAs include the androgen biosynthesis inhibitor abiraterone (with prednisone) and AR signaling inhibitors enzalutamide/apalutamide.
