Multiple Myeloma Clinical Trial
Testing GSK2636771 as a Potential Targeted Treatment in Cancers With PTEN Loss of Expression (MATCH-Subprotocol P)
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.
I. To evaluate the proportion of patients with objective response (OR) to targeted study agent(s) in patients with advanced refractory cancers/lymphomas/multiple myeloma.
I. To evaluate the proportion of patients alive and progression free at 6 months of treatment with targeted study agent in patients with advanced refractory cancers/lymphomas/multiple myeloma.
II. To evaluate time until death or disease progression. III. To identify potential predictive biomarkers beyond the genomic alteration by which treatment is assigned or resistance mechanisms using additional genomic, ribonucleic acid (RNA), protein and imaging-based assessment platforms.
IV. To assess whether radiomic phenotypes obtained from pre-treatment imaging and changes from pre- through post-therapy imaging can predict objective response and progression free survival and to evaluate the association between pre-treatment radiomic phenotypes and targeted gene mutation patterns of tumor biopsy specimens.
Patients receive PI3K-beta inhibitor GSK2636771 (GSK2636771) orally (PO) once daily (QD) on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 3 months if less than 2 years from study entry, and then every 6 months for year 3 from study entry.
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
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:
