OTP-01 for Cancer
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a new drug, OTP-01, to determine the best dose for adults with solid tumors that can't be cured or removed. Researchers aim to assess the safety of OTP-01, identify potential side effects, and evaluate its ability to shrink tumors. Participants will receive the drug intravenously, undergo blood tests, and have scans to monitor tumor changes. Individuals with advanced solid tumors who have not responded to other treatments might be suitable for this study. As a Phase 1 trial, participants will be among the first to receive this new treatment, aiding researchers in understanding its effects in people.
Will I have to stop taking my current medications?
The trial does not specify if you need to stop taking your current medications, but you cannot have had chemotherapy, immunotherapy, or investigational anticancer therapy within 3 weeks before starting the study drug. Also, you cannot be on high-dose systemic corticosteroids.
Is there any evidence suggesting that OTP-01 is safe for humans?
Research shows that OTP-01 is under study to assess its safety and tolerability. As this clinical trial is in its early stages, the main goal is to determine the optimal dose and monitor for side effects. Although detailed safety information isn't available yet, early-phase trials mark the first step in testing a treatment in humans, making safety a top priority. Researchers closely monitor participants for any adverse effects.
In this trial, participants will receive OTP-01 through an intravenous infusion, with doses administered no more than once a week. Frequent blood tests will evaluate how the body processes the drug and ensure its safety. This careful approach helps identify potential risks early. While specific safety results for OTP-01 aren't available, early-phase trials are designed to closely monitor for side effects to ensure participant safety.12345Why do researchers think this study treatment might be promising?
OTP-01 is unique because it targets cancer cells with a novel mechanism that differs from traditional chemotherapy or targeted therapy. Unlike standard treatments that often attack both cancerous and healthy cells, OTP-01 is designed to specifically disrupt cancer cell growth pathways, potentially leading to fewer side effects and more precise treatment. Researchers are excited about OTP-01 because it could represent a new class of cancer therapy that offers improved outcomes by precisely targeting cancer cells while sparing normal tissue.
What evidence suggests that OTP-01 might be an effective treatment for cancer?
Research shows that OTP-01 might help treat solid tumors by slowing or stopping their growth. Studies comparing different treatments have found that patients treated with OTP in a different setting had survival rates of 75% after one year, 38% after three years, and 30% after five years. These findings suggest that OTP-01 could improve survival chances for people with solid tumors. While detailed information about OTP-01's effects on solid tumors is still being gathered, it targets and kills cancer cells, potentially shrinking tumors. This trial will explore OTP-01's effects through two experimental arms: Monotherapy Dose Escalation with Backfill and Monotherapy Dose Expansion, to determine if these effects apply to a wider group of people with solid tumors.26789
