Registration Number
NCT06589596

Brief Summary

This is an open-label, multicenter, first-in-human dose escalation and dose expansion study to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary antitumor activity of BGB-58067 as monotherapy in participants with advanced solid tumors and with methylthioadenosine phosphorylase (MTAP) deficiency.

Detailed Description

BGB-58067 is a new drug designed to target a specific protein called protein arginine methyltransferase 5 (PRMT5). This protein is involved in many cell activities and can promote cancer growth when it is overactive. High levels of PRMT5 are linked to poor outcomes in several types of cancer.

This new study will check how safe and helpful a potential anticancer drug called BGB-58067 is. This drug will be tested as monotherapy in participants with advanced solid tumors and with MTAP deficiency.

GroupInterventionDescription
Phase 1a: Dose Escalation and Safety ExpansionBGB-58067Sequential cohorts of increasing dose levels of BGB-58067 as monotherapy will be evaluated.
Phase 1b: Dose Expansion and OptimizationBGB-58067Recommended Dose(s) for Expansion (RDFE\[s\]) of BGB-58067 as monotherapy will be evaluated for selected indications based on emerging data.
Primary Outcome Measures
NameTimeMethod
Phase 1a: Number of Participants with Adverse Events and Serious Adverse EventsFrom first dose of the study drug(s) to 30 days after the last dose or initiation of a new anticancer therapy, whichever occurs first (approximately 2 years)

Number of participants with AEs and SAEs, including findings from physical examinations, electrocardiograms (ECGs), and laboratory assessments, and that meet protocol-defined dose-limiting toxicity (DLT) criteria.

Phase 1a: Maximum Tolerated Dose (MTD) or Maximum Administered Dose (MAD)Approximately 1.5 years

MTD is defined as the highest dose evaluated for which estimated toxicity rate is the closest to the target toxicity rate. MAD is defined as the highest dose administered if MTD is not reached.

Phase 1a: Recommended Dose(s) for Expansion (RDFE[s]) of BGB-58067Approximately 2 years

RDFE of BGB-58067 will be determined based upon the MTD or MAD.

Phase 1b: Recommended Phase 2 Dose (RP2D) of BGB-58067Approximately 2 years

RP2D established from Phase 1a for BGB-58067 for administration in selected tumor types.

Phase 1b: Objective Response Rate (ORR)Approximately 2 years

ORR is defined as the percentage of participants with confirmed complete response (CR) or partial response (PR), as assessed by the investigator.

Secondary Outcome Measures
NameTimeMethod
Phase 1a: Objective Response Rate (ORR)Approximately 2 years

ORR is defined as the percentage of participants with confirmed CR or PR, as assessed by the investigator.

Phase 1a: Maximum observed plasma concentration (Cmax) of BGB-58067Approximately 2 years
Phase 1a: Minimum observed plasma concentration (Cmin) of BGB-58067Approximately 2 years
Phase 1a: Time to reach maximum observed plasma concentration (Tmax) of BGB-58067Approximately 2 years
Phase 1a: Apparent oral clearance (CL/F) for BGB-58067Approximately 2 years
Phase 1a: Half life (t1/2) of BGB-58067Approximately 2 years
Phase 1a: Area under the concentration-time curve (AUC) of BGB-58067Approximately 2 years
Phase 1a: Apparent volume of distribution (Vz/F) for BGB-58067Approximately 2 years
Phase 1a: Accumulation ratio (AR) for BGB-58067Approximately 2 years
Phase 1a and 1b: plasma concentrations of BGB-58067Approximately 2 years
Phase 1a and 1b: Duration of Response (DOR)Approximately 2 years

DOR is defined as the time from the first determination of an objective response until first documentation of progression or death, whichever occurs first, as assessed by the investigator.

Phase 1a and 1b: Disease Control Rate (DCR)Approximately 2 years

DCR is defined as the percentage of participants with best overall response of a CR, PR, and stable disease, as assessed by the investigator.

Phase 1b: Number of Participants with AEs and SAEsFrom first dose of the study drug(s) to 30 days after the last dose or initiation of a new anticancer therapy, whichever occurs first (approximately 2 years)

Number of participants with AEs and SAEs, including findings from physical examinations, electrocardiograms (ECGs), and laboratory assessments.

Phase 1b: Progression-Free Survival (PFS)Approximately 2 years

PFS is defined as the time from the date of the first dose of study drug to the date of first documentation of progressive disease assessed by investigator or death, whichever occurs first, as assessed by the investigator.
