Testing Copanlisib as a Potential Targeted Treatment in Cancers With PIK3CA Mutations (MATCH-Subprotocol Z1F)

This phase II MATCH treatment trial identifies the effects of copanlisib hydrochloride (copanlisib) in patients whose cancer has a genetic change called PIK3CA mutation. Copanlisib may stop the growth of cancer cells by blocking PIK3, a protein needed for cell growth. Researchers hope to learn if copanlisib will shrink this type of cancer or stop its growth.

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.

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.

OUTLINE:

Patients receive copanlisib intravenously (IV) over 1 hour on days 1, 8, and 15 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients also undergo tumor biopsies at screening and end of treatment and computed tomography (CT) or magnetic resonance imaging (MRI) at baseline, every 2 cycles for the first 26 cycles, and then every 3 cycles thereafter until progressive disease or start of another MATCH treatment step.

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.
