Testing Copanlisib as Potentially Targeting Treatment in Cancers With PTEN Loss (MATCH - Subprotocol Z1G)

Inclusion Criteria: * Patients must have met applicable eligibility criteria in the Master MATCH Protocol EAY131/ NCI-2015-00054 prior to registration to treatment subprotocol * Patients must fulfill all eligibility criteria outlined in Section 3.1 of MATCH Master Protocol (excluding Section 3.1.6) at the time of registration to treatment step (Step 1, 3, 5, 7) * Patients must have complete loss of cytoplasmic and nuclear PTEN by immunohistochemistry (ICH) as determined via the MATCH Master Protocol and described in Appendix I. Patients can have any PTEN mutation or deletion status, but MUST have PTEN loss by IHC * NOTE: For patients entering the study, all patients must have PTEN IHC performed as described in the MATCH Master Protocol. This includes patients entering the study via the outside assay process * Patients must not have co-existing aberrations in the MAPK or PI3K/MTOR pathways as determined by the MATCH screening assessment in NRAS, HRAS, KRAS, BRAF, PIK3CA, AKT or mTOR * 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 not have known hypersensitivity to copanlisib or compounds of similar chemical or biologic composition * Patients must not have had prior treatment with copanlisib or other PI3K inhibitors, AKT inhibitors or mTOR inhibit…
