Breast Cancer Clinical Trial
Testing GDC-0032 (Taselisib) as a Potential Targeted Treatment in Cancers With PIK3CA Genetic Changes (MATCH-Subprotocol I)
This phase II MATCH treatment trial identifies the effects of GDC-0032 (taselisib) in patients whose cancer has a genetic change called PIK3CA mutation. Taselisib may stop the growth of cancer cells by blocking PIK3CA, a protein that may be needed for cell growth. Researchers hope to learn if taselisib 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 taselisib 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 a PIK3CA mutation as determined via the MATCH Master Protocol
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 with known left ventricular dysfunction must have echocardiogram (ECHO) or multigated acquisition scan (MUGA) within 4 weeks prior to registration to treatment and must not have left ventricular ejection fraction (LVEF) < institutional lower limit of normal (LLN). If the LLN is not defined at a site, the LVEF must be > 50% for the patient to be eligible
Patients must have a fasting glucose =< 125 mg/dL
NOTE: Please provide clear documentation that the glucose test was conducted at a fasting state
