What You Need to Know Before You Apply

What is the purpose of this trial?

This is a Phase 1/2, open-label, multi-center, non-randomized, dose-escalation study to be conducted in two parts: the Dose Escalation Phase and the Dose Expansion Phase. The Dose Escalation Phase will determine the Maximum Tolerated Dose (MTD) and recommended Phase 2 dose(s) (RP2D) of PT-112 Injection and evaluate its safety and tolerability, and PK (pharmacokinetics).The Dose Escalation Phase is complete and no longer enrolling.The Dose Expansion Phase has two cohorts: one cohort for the study of PT-112 in patients with thymoma and thymic carcinoma (Cohort A), and one cohort for the study of PT-112 in metastatic castrate-resistant prostate cancer (mCRPC) (Cohort D).

This trial is for adults with advanced solid tumors, including metastatic castrate-resistant prostate cancer, who have limited treatment options. Participants must be in good physical condition (ECOG 0-1), have stable brain metastases if present, and adequate organ function. They can't join if they've had extensive chemotherapy, uncontrolled heart issues, recent major surgery or radiotherapy, active infections or certain previous cancers.

What Are the Treatments Tested in This Trial?

Interventions

  • PT-112 Injection
Trial Overview The study tests PT-112 Injection's safety and how the body processes it. It has two parts: an initial phase to find the highest dose patients can tolerate without severe side effects (completed) and a second phase focusing on specific cancers like thymoma/thymic carcinoma and metastatic prostate cancer.
