This is a multicenter, single-arm, open label, study consisting of two cohorts. Cohort 2 explores the combination of copanlisib and pembrolizumab in patients with relapsed or refractory NKTCL, who have received at least 1 prior systemic therapy. Cohort 2 will include a phase 1 portion (cohort 2a) to determine the recommended phase 2 dose (RP2D) utilizing a standard 3+3 design, followed by a phase II portion where patients will be treated at the RP2D (cohort 2b). The primary endpoint for cohort 1 was progression-free survival; the primary endpoint for cohort 2a will be to determine RP2D for the combination therapy; and overall response rate at the end of 4 treatment cycles for cohort 2b. Patients will be assessed for response with PET CT or CT every 12 weeks using the revised Cheson criteria. Correlative endpoints will be exploratory and assess PD-1 expression on peripheral blood lymphocytes; peripheral blood T-cell and NK-cell functional assays; PD-1 and PD-L1 expression on tumor tissue; tumor infiltrating lymphocytes and gene expression panels using the nanostring technology as prognostic and predictive biomarkers, as well as monitoring of minimal residual disease via high-throughput sequencing of cell free tumor DNA, and exosome analysis.

Study summary:

Patients with relapsed or refractory (RR) NK and T-cell Lymphoma (NKTCL), who have received at least 1 prior systemic therapy, were enrolled in cohort 1. The study design for cohort 1 was a single arm phase II 2-stage design, to explore monotherapy with the PD-1 antibody pembrolizumab (or MK-3475) given intravenously at a fixed dose of 200mg every 3 weeks for up to 36 cycles. Enrollment to this cohort has been completed.

Female subjects of childbearing potential should be willing to use 2 methods of birth control or be surgically sterile, or abstain from heterosexual activity for the course of the study through 120 days after the last dose of study medication (Reference Section 5.5.2). Subjects of childbearing potential are those who have not been surgically sterilized or have not been free from menses for greater than 1 year. 9. Male subjects should agree to use an adequate method of contraception starting with the first dose of study therapy through 120 days after the last dose of study therapy. Exclusion Criteria: 1.

Patients diagnosed with Adult T-cell Leukemia/Lymphoma (ATLL) or T-cell PLL 3. Has a diagnosis of immunodeficiency or is receiving systemic steroid therapy or any other form of immunosuppressive therapy within 7 days prior to the first dose of trial treatment. 4. Has had a prior monoclonal antibody within 4 weeks prior to study Day 1 or who has not recovered (i.e., worse than Grade 1 or at baseline) from adverse events due to agents administered more than 4 weeks earlier. 5. Has had prior chemotherapy, targeted small molecule therapy, or radiation therapy within 2 weeks prior to study Day 1 or who has not recovered (i.e., ≤ Grade 1 or at baseline) from adverse events due to a previously administered agent. - Note: Subjects with worse than Grade 2 neuropathy are an exception to this criterion and may qualify for the study. - Note: If subject received major surgery, they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting therapy. 6.
