A Phase 1/2, Open-label, Multicenter Study to Investigate the Safety, Pharmacokinetics, and Efficacy of Fadraciclib (CYC065), an Oral CDK2/9 Inhibitor, in Subjects With Advanced Solid Tumors and Lymphoma

Primary objectives: Phase 1: To determine the maximum-tolerated dose (MTD) and/or recommended Phase 2 dose (RP2D) of fadraciclib when administered orally twice daily (BID) in 28-day cycles in adult subjects with advanced solid tumors and lymphoma Phase 2: To evaluate preliminary efficacy of fadraciclib as measured by overall response rate (ORR) in subjects with locally advanced, recurrent, or metastatic, histologically confirmed advanced solid tumors or lymphoma who have failed all standard therapies or for whom standard therapy does not exist Primary endpoints: Phase 1: The incidence rate of dose-limiting toxicities (first cycle only) at each dose level Phase 2:ORR according to Response Evaluation Criteria in Solid Tumors: RECIST guidelines (Lugano Criteria for lymphoma, mSWAT for CTCL) for each tumor type
