Study Summary

This trial is testing a new cancer drug, PT-112. It is in two parts, the first of which has finished enrolling. The second part is testing PT-112's safety and how well it works in patients with thymoma or thymic carcinoma, and in patients with metastatic castrate-resistant prostate cancer.

Who is the study for?
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.Check my eligibility
What is being tested?
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.See study design
What are the potential side effects?
Potential side effects of PT-112 are not detailed here but may include typical reactions to cancer treatments such as fatigue, nausea, blood count changes leading to increased infection risk or bleeding problems; organ-specific toxicity could also occur.
