简要总结
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.
详细描述
PRIMARY OBJECTIVE:
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.
SECONDARY OBJECTIVES:
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.

入选标准
- •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
- •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

研究组 & 干预措施
Treatment (taselisib)
Patients receive taselisib 4 mg PO QD on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
干预措施: Taselisib (Drug)
结局指标
主要结局
Overall Response Rate (ORR)
时间窗: 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
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.
次要结局
- 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)
- 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)
