Testing GSK2636771 as a Potential Targeted Treatment in Cancers With PTEN Loss of Expression (MATCH-Subprotocol P)

United States35 participantsStarted 2016-03-21

Plain-language summary

This phase II MATCH treatment trial identifies the effects of GSK2636771 in patients whose cancer has a complete loss of PTEN expression. GSK2636771 may block a protein called PI3K-beta, which may be needed for growth of cancer cells with complete loss of PTEN expression. Researchers hope to learn if GSK2636771 will shrink this type of cancer or stop its growth.

Inclusion Criteria: * Patients must have met applicable eligibility criteria in the Master MATCH Protocol prior to registration to treatment subprotocol * Patients must have an electrocardiogram (ECG) within 8 weeks prior to treatment assignment and must have no clinically important abnormalities in rhythm, conduction or morphology of resting ECG (e.g. complete left bundle branch block, third degree heart block) * Patients must have complete loss of cytoplasmic and nuclear PTEN staining on immunohistochemistry as determined by the MATCH PTEN immunohistochemistry (IHC) assay performed at MD Anderson. Patients can have any PTEN mutation or deletion status, but MUST have PTEN loss by IHC * Patients must have hemoglobin \>= 9 g/dL * Patients must have a serum creatinine that is \< 1.5 x upper limit of normal (ULN) or have a 24-hour creatinine clearance of \> 50 mL/min Exclusion Criteria: * Patients must not have known hypersensitivity to GSK2636771 or compounds of similar chemical or biologic composition * Patients must not have tumors harboring co-existing aberrations activating the PI3K/MTOR and MAPK pathways, such as PIK3CA, PIK3R1, BRAF, KRAS and AKT1, TSC1/2, mTOR, NF2, NRAS, HRAS, NF1 * Patients must not have received prior treatment with agents targeting the PI3K beta, AKT, or mTOR: * This includes (but is not limited to): * mTOR inhibitors: temsirolimus, everolimus, ridaforolimus, sirolimus, salirasib, CC-223, INK128, DS-3078, CC-115, AZD-2014 * Dual PI3K/mTO…

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.
