Clinical Trial Summary

This is a Phase 1/2, multicenter, open-label study to evaluate the efficacy, and safety of various combinations with selinexor in participants with RR DLBCL. The study will be conducted in two phases: Phase 1 and 2. The Phase 1 of the study will be a standard 3 + 3 dose escalation to determine the maximal tolerated dose (MTD), recommended Phase 2 dose (RP2D) for each treatment arm, and assess the dose limiting toxicities (DLTs). The Phase 2 of the study will be a dose expansion study to assess the efficacy and safety of for RP2D selected at the end of Phase 1 of the study for each treatment arm.

Any AE, by Cycle 1 Day 1 (C1D1), which has not recovered to Grade =1 (CTCAE, v. 5.0), or returned to baseline, related to the previous DLBCL therapy, except alopecia. 7. Major surgery <14 days of C1D1. 8. Autologous stem cell transplant (SCT) <100 days or allogeneic SCT <180 days prior to C1D1 or active graft-versus-host disease after allogeneic SCT (or cannot discontinue graft versus host disease [GVHD] treatment or prophylaxis). 9. Prior chimeric antigen receptor T cell (CAR-T cell) infusion at any time (Phase 1 only); prior CAR-T cell infusion =120 days prior to C1D1 (Phase 2 only). 10. Any life-threatening illness, medical condition, or organ system dysfunction which, in the Investigator's opinion, could compromise the participant's safety, or able to comply with the study procedures. 11. Uncontrolled (i.e., clinically unstable) infection requiring parenteral antibiotics, antivirals, or antifungals within 7 days prior to first dose of study treatment; however, prophylactic use of these agents is acceptable (including parenteral). 12. Inability to swallow tablets, malabsorption syndrome, or any other GI disease or dysfunction that could interfere with absorption of study treatment. 13. Breastfeeding women or pregnant women. 14. Inability or unwillingness to sign informed consent form. 15.

Known allergy to any of the drug planned to be given. The following are Arm Specific exclusion criteria: 17. Arm B (S-PR): Serum total bilirubin >1.5 * ULN, Neuropathy Grade =2 (CTCAE, v5.0). 18. Arm C (S-PBR): Serum total bilirubin >1.5 * ULN, Neuropathy Grade =2 (CTCAE, v5.0). 19. Arm D (S-R-GemOx): Neuropathy Grade 2= (CTCAE, v5.0) interstitial lung disease or pulmonary fibrosis.
