TQB3525 for Advanced Bone Sarcomas With PI3KA Mutations or PTEN Loss
China29 participantsStarted 2020-10-01
Plain-language summary
The PI3K, protein kinase B (AKT), and mTOR signaling network promotes cell growth, survival, metabolism, and motility, but becomes a critical oncogenic driver under aberrant conditions that control the tumor microenvironment and angiogenesis. The PI3K-AKT-mTOR axis is the most frequently deregulated signaling pathway in primary osteosarcoma and other bone tumors. PI3Ka has high rates of 25-50% activating mutations associated with tumor formation in osteosarcoma. Other causes of pathway hyperactivation include loss of function of the tumor suppressor PTEN, gain-of-function mutations in AKT and PDK1, or upregulation of receptor tyrosine kinases. TQB3525 is an orally bioavailable, potent, dual catalytic site inhibitor of PI3Ka and PI3Kd. Tumor growth inhibition has been demonstrated in multiple xenograft osteosarcoma models with PI3K-mutant, PTEN-null cell lines. The investigators try to investigate TQB3525 in primary osteosarcoma and other bone tumors for its safety, tolerability, dose-limiting toxicities (DLT), MTD and antitumor efficacy.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
