Details and patient eligibility

About

The goal of this clinical trial is to evaluate the safety and tolerability of escalating doses of LP-284 and to determine the maximum tolerated dose (MTD) and the recommended Phase 2 dose (RP2D) in patients with relapsed or refractory (R/R) lymphomas and solid tumors. The secondary objectives are to characterize the pharmacokinetics (PK) of LP-284 and to assess clinical activity of LP-284.

Full description

This FIH study is an open-label Phase 1a/1b dose escalation and dose expansion study in adult patients with R/R lymphoma and solid tumors. Patients who provide informed consent and meet the eligibility criteria for the study will be enrolled and treated with LP-284 administered intravenously (IV) on Days 1, 8, 15 of a 28-day schedule. The study will be conducted in 2 parts: dose escalation with MTD and/or RP2D confirmation (Phase 1a) and dose expansion (Phase 1b). Up to 30 evaluable patients will be enrolled in Phase 1a; the total number of patients will depend on the number of dose levels explored. Up to 40 evaluable patients will be enrolled in each of the 2 cohorts of MCL and DLBCL tumors in Phase 1b. Patients will remain on study treatment for up to a total of one-year OR until disease progression, unacceptable toxicity, withdrawal of consent, any study-specific discontinuation criteria are met, or the Investigator determines that it is in the best interest of the patient to discontinue study treatment, whichever is shorter.

Phase 1 Single Arm Multicenter Study to Assess the Safety and Tolerability of LP-284
Experimental group
Description:
The Phase 1a dose escalation portion of the study will identify the maximum tolerated dose (MTD) and/or optimal dose(s) of LP-284 as the RP2D, based on all available safety, PK, PD, and/or preliminary efficacy data. Phase 1b will consist of the dose expansion portion in a separate cohort(s) of patients to further evaluate the safety of LP-284 at the RP2D and obtain preliminary estimates of clinical activity of LP-284 in patients with DLBCL and MCL.
