A Phase 1/1b Study Evaluating the Safety, Pharmacokinetics, and Preliminary Efficacy of LP-118 in Subjects With Relapsed or Refractory Hematological Malignancies

This is a Phase 1, multi-center, open-label study with a dose-escalation phase (Phase 1a) and a cohort expansion phase (Phase 1b), to evaluate the safety, tolerability, and PK profile of LP-118 under a once daily oral dosing schedule in up to 100 subjects.

Primary objectives of the study are to assess the safety and tolerability profile, determine the maximum tolerated dose (MTD), and/or the recommended Phase 2 dose (RP2D) of LP-118 administered once daily (QD) as a single agent dosed orally in adult subjects with relapsed/refractory NHL, RT, MM, T-PLL (Group 1) and acute leukemia (AML, ALL), MDS, MDS/MPN, MF (Group 2).

     Secondary objectives of the study are to evaluate preliminary efficacy regarding the effect of LP-118 on objective response rate (ORR) using disease specific response criteria, progression-free survival (PFS), and duration of response (DOR), and overall survival (OS) in adult subjects with relapsed/refractory NHL, RT, MM, T-PLL (Group 1); and acute leukemia (AML, ALL), MDS, MDS/MPN, MF (Group 2

             - Relapsed or refractory ALL subjects with B cell phenotype who have received at least two prior regimens (such as multi-agent chemotherapy and/or tyrosine kinase inhibitors including bosutinib, dasatinib, imatinib, nilotinib or ponatinib) and failed, or are currently ineligible/intolerant for CD19-based target therapy (e.g. Blinatumomab); Relapsed or refractory ALL subjects with T cell phenotype who have received at least one prior therapy and failed.

         - For Group 2 AML and ALL subjects only, white blood cell (WBC) count ≤ 25 × 109 cells/L at the time of enrollment (glucocorticoids or hydroxyurea is permitted to control WBC count prior to and during therapy).
