Brief Summary

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.

Conditions

Refractory Lymphoma; Refractory Multiple Myeloma; Advanced Lymphoma; Advanced Malignant Solid Neoplasm; Hematopoietic and Lymphoid Cell Neoplasm; Refractory Malignant Solid Neoplasm

Outcome Measures

Primary Outcomes (1)

• Overall Response Rate (ORR)

  Overall response rate was defined as the proportion of patients with best overall response of complete response (CR) or partial response (PR) among all eligible and treated patients. Best overall response was evaluated using the Response Evaluation Criteria in Solid Tumors version 1.1, the Cheson (2014) criteria for lymphoma patients, and the Response Assessment in Neuro-Oncology criteria for glioblastoma patients. The 90% two-sided binomial exact confidence interval was calculated for ORR.

  Tumor assessments occurred at baseline, then every 2 cycles for the first 26 cycles and every 3 cycles thereafter until disease progression, up to 3 years post registration

Secondary Outcomes (2)

• 6-Month Progression-free Survival (PFS) Rate

  Assessed at baseline, then every 2 cycles for the first 26 cycles, and every 3 cycles thereafter until disease progression, up to 3 years post registration, from which 6-month PFS is determined

• Progression-free Survival (PFS)

  Assessed at baseline, then every 2 cycles for the first 26 cycles and every 3 cycles thereafter until disease progression, up to 3 years post registration

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
• Patients with prior treatment with an mTOR inhibitor are acceptable. These include, but are not limited to: temsirolimus, everolimus, ridaforolimus, sirolimus, CC-223, MLN128 (INK128), DS-3078, CC-115, AZD-2014, AZD8055
