Summary

This trial tests TP-1287, an oral medicine that blocks a protein needed by cancer cells to grow. It targets patients with advanced cancers who do not respond to standard treatments. The goal is to find the best dose and see if it helps control the cancer.

Who is the study for?
This trial is for adults with advanced solid tumors who've had 1-3 prior treatments including an anthracycline, are not responding to standard therapy, and have a life expectancy of at least 3 months. Ewing sarcoma patients over 12 years old weighing more than 40 kg can also join. Participants must have acceptable organ function and agree to use contraception.
What is being tested?
TP-1287, an oral drug designed to inhibit CDK9, is being tested in this Phase 1 study. The goal is to find the highest dose patients can take without serious side effects (MTD) by gradually increasing doses among small groups of participants (dose escalation), then giving this dose to more people (dose expansion).
What are the potential side effects?
Potential side effects include those common with cancer drugs targeting cell division such as fatigue, nausea, diarrhea, low blood counts leading to increased infection risk or bleeding problems. Specific side effects related to TP-1287 will be monitored closely due to its experimental nature.

Mechanism Of Action

Prior Approvals
Other Research
Common treatments for sarcoma include chemotherapy, targeted therapy, and immunotherapy. Chemotherapy agents like doxorubicin work by damaging the DNA of cancer cells, leading to cell death. Targeted therapies, such as tyrosine kinase inhibitors (e.g., pazopanib) and mTOR inhibitors (e.g., temsirolimus), interfere with specific molecular pathways crucial for tumor growth and survival. CDK inhibitors, like the investigational CDK9 inhibitor TP-1287, block cyclin-dependent kinases involved in cell cycle regulation, potentially halting tumor proliferation. These treatments are vital for sarcoma patients due to the complex and aggressive nature of these tumors, often requiring a multifaceted approach to improve outcomes.
