Experimental

Arm Label

Dose Escalation Phase

Dose Expansion Phase

Arm Description

Three to six subjects per treatment cohort will be assigned to receive sequentially higher oral doses of LP-168 on a once or twice daily schedule for 28 days, starting at a dose of 100 mg/day.

Additional subjects will be recruited to further explore the safety, tolerability, PK, and efficacy in specific subject subgroups.

Outcomes

Primary Outcome Measures

Maximum Tolerated Dose (MTD)
When more than 1 DLT occurs in ≤ 6 subjects in a dosing cohort, dose escalation will be stopped and this dose level will be identified as the non-tolerated dose. Doses between the non-tolerated dose and the preceding lower dose, where ≤ 1 DLT occurred, may be explored to more precisely define the MTD.
Recommended Phase 2 dose (RP2D)
The RP2D may be as high as the MTD or a lower dose and will be selected in discussion with the Investigators and the Sponsor based on longer term safety data, preliminary efficacy data, and PK data.

Secondary Outcome Measures

Progression-Free Survival (PFS)
PFS is measured from the time of first study drug administration until the first date that recurrent or progressive disease is objectively documented.
Objective Response Rate (ORR)
ORR is defined as the sum of complete response (CR) and partial remission rates.
Duration of Response (DOR)
The duration of overall response is measured from the time measurement criteria are met for CR or PR (which is first recorded) until the first date that recurrent or progressive disease is objectively documented

5. Study Description

Brief Summary
This is a phase I, multi-center, open-label, dose-escalation study to evaluate the safety, tolerability, pharmacokinetics and clinical activity of LP-168 in subjects with relapsed or refractory B-cell malignancies. LP-168 is a small molecule inhibitor.
Detailed Description
The primary objectives for 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-168 administered once or twice daily as a single agent dosed orally in adult subjects with relapsed/refractory B-cell Malignancies (CLL/SLL, WM, FL, MCL, MZL, DLBCL, HCL); and to characterize the pharmacokinetics (PK) profile of LP-168 in adult subjects with relapsed/refractory B-cell Malignancies (CLL/SLL, WM, FL, MCL, MZL, DLBCL, HCL). Secondary objectives of the study are to evaluate preliminary efficacy regarding the effect of LP-168 on progression-free survival (PFS), objective response rate (ORR), and duration of response (DOR) in adult subjects with relapsed/refractory B-cell Malignancies (CLL/SLL, WM, FL, MCL, MZL, DLBCL, HCL). Once the MTD is declared and the RP2D is established, additional subjects will be enrolled in a cohort expansion phase (Phase 1b).

Treatment
Study Phase
Phase 1
Interventional Study Model
Sequential Assignment
Model Description
A classic "3+3" design will be used to establish the dose-limiting toxicity (DLT), MTD, and RP2D. Three to six subjects per treatment cohort will be assigned to receive sequentially higher oral doses of LP-168 on a once or twice daily schedule for 28 days (a "Cycle"), starting at a dose of 100 mg/day. Once all subjects in a given cohort have reached Cycle 1 Day 28, these data will be reviewed by the Safety Review Committee (SRC) for decisions on dose escalation for a new dose cohort. Subjects will receive once-daily or twice-daily oral dose of LP-168 until disease progression, unacceptable toxicity, or a clinical observation satisfying another criterion for withdrawal from treatment is noted.
