Study Details

Study Description

Brief Summary

This is an open-label, dose-escalation/dose-expansion, phase I clinical trial study to investigate the safety, tolerability, and efficacy of HWH340. In addition, the pharmacokinetic characteristics will also be investigated. Three parts are included in this study.

Condition or Disease	Intervention/Treatment	Phase
Advanced Solid Tumors HRD BRCA Mutation	Drug: HWH340 tablet	Phase 1

Detailed Description

Part one is a single-dose study on tolerance and pharmacokinetics, in which 21-42 patients with advanced solid tumors would be enrolled. Patients will receive escalating dose groups of HWH340 tablet.

Part two is a multiple-dose study on tolerance and pharmacokinetics. Based on the safety assessment, three or four groups would be chosen to conduct the study. 9-24 patients with advanced solid tumors will be enrolled.

Part three is a dose expansion stage on safety and efficacy. Two to four dose-groups would be chosen to conduct the study. 40-60 patients with advanced solid tumors with BRCA mutation OR homologous recombination deficiency (HRD) will be enrolled.

Arms and Interventions

Arm	Intervention/Treatment
Experimental: HWH340 monotherapy HWH340 tablet, oral administration	Drug: HWH340 tablet single escalating dose study starts from 20 mg as the initial dose until the maximum dose group (520mg) or maximum tolerated dose (MTD) has been reached. multiple-dose study conducted on oral HWH340 tablet BID. The DLTs evaluating period is 4 weeks and the safety evaluation period lasts till 4 weeks after drug withdrawal. dose-expansion study conducted on oral HWH340 tablet BID in 2 to 4 dose groups.

Tumor Objective Response Rate（ORR） [on day 42 post dose]
Response and progression is evaluated using internationally accepted response criteria and definitions proposed by the RECIST criteria.
Area under the plasma concentration versus time curve (AUC) [Prior to 0 hour, and 0.5, 1, 2, 4, 8, 12, 36 and 48 hours post dose]
AUC referred to area under the plasma concentration-time curve post dose.
Time for Maximum Observed Plasma Concentration (Tmax) [Prior to 0 hour, and 0.5, 1, 2, 4, 8, 12, 36 and 48 hours post dose]
Blood samples are obtained and plasma concentrations of HWH340 are determined using a validated atomic absorption spectrometry method.
Disease Control Rate (DCR) [through study completion, an average of 1 year]
Response and progression is evaluated using internationally accepted response criteria and definitions proposed by the RECIST criteria.
Objective Response Rate by Investigator [through study completion, an average of 1 year]
Response and progression is evaluated using internationally accepted response criteria and definitions proposed by the RECIST criteria.
Disease control rate [through study completion, an average of 1 year]
Response and progression is evaluated using internationally accepted response criteria and definitions proposed by the RECIST criteria.
Duration of response [through study completion, an average of 1 year]
Response and progression is evaluated using internationally accepted response criteria and definitions proposed by the RECIST criteria.
Best overall response [through study completion, an average of 1 year]
Response and progression is evaluated using internationally accepted response criteria and definitions proposed by the RECIST criteria.
Progression Free Survival [through study completion, an average of 1 year]
Response and progression is evaluated using internationally accepted response criteria and definitions proposed by the RECIST criteria.
