Clinical Trials for Prostate Cancer

A Phase 1/2 Open-label, Multicenter Study to Assess the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics, and Efficacy of PC14586 in Patients With Locally Advanced or Metastatic Solid Tumors Harboring a TP53 Y220C Mutation (PYNNACLE)

Active drug

Investigational drug(s) in this trial have shown anticancer activity in clinical trials

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 (and selected adolescents) with locally advanced or metastatic solid tumors harboring a TP53 Y220C mutation, who have progressed after at least one prior therapy, to receive rezatapopt (PC14586)—a selective oral p53 reactivator targeting the Y220C mutant—as monotherapy. Patients must have ECOG 0-1 and measurable disease; cohorts include ovarian, lung, breast, endometrial, and other solid tumors, with KRAS wild-type status required for some.

MK-5684-01A Substudy: A Phase 1/2 Umbrella Substudy of MK-5684-U01 Master Protocol to Evaluate the Safety and Efficacy of MK-5684-based Treatment Combinations or MK-5684 Alone in Participants With Metastatic Castration-resistant Prostate Cancer (mCRPC)

Active drug

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 metastatic castration‑resistant prostate adenocarcinoma after 1–2 prior next‑generation hormonal agents, on continued ADT, are randomized to the CYP11A1 inhibitor opevesostat (MK‑5684) with physiologic steroid replacement as monotherapy or combined with olaparib, docetaxel, or cabazitaxel. Opevesostat blocks steroidogenesis upstream of androgen synthesis to suppress AR signaling; combinations aim to define RP2D and assess antitumor activity.
