A Study of LP-168 in Participants with Relapse or Refractory B-Cell Lymphoma

Phase 1
Recruiting
Conditions
B-cell Lymphoma
Interventions
Drug: LP-168 tablet
Registration Number
NCT04993690
Lead Sponsor
Guangzhou Lupeng Pharmaceutical Company LTD.
Brief Summary

This is an open-label, multi-center Phase 1/2 study of oral LP-168 in patients with CLL/SLL and NHL who have failed or are intolerant to standard of care.

Detailed Description

This study includes 2 parts: phase 1a (LP-168 monotherapy dose escalation) and phase 1b (LP-168 dose expansion). In phase 1a, patients will be enrolled using an 3+3 design. The starting dose of LP-168 in oral tablet form is 100 mg/day (e.g., 100 mg once daily \[QD\]). Once the MTD and/or RP2D is identified in phase 1a dose escalation, enrollment will continue to phase 1b dose expansion. Cycle length will be 28 days.

Any gastrointestinal conditions that may severely affect the study drug absorption or pharmacokinetic parameters.
  • Subjects who cannot tolerate urine collection, venipuncture, lymph node biopsy, and bone marrow aspiration.
