A Study of ILB2109 in Patients With Advanced Solid Malignancies

Phase 1
Active, not recruiting
Conditions
Advanced Solid Tumor
Interventions
Registration Number
NCT05278546
Lead Sponsor
Innolake Biopharm
Brief Summary

This is a multicenter, open-label, phase Ia study to evaluate the safety, tolerability and preliminary efficacy of ILB2109, a A2a receptor antagonist, in patients with locally advanced or metastatic solid malignancies.

Detailed Description

This is a two-part study consists of dose escalation and dose expansion. The dose escalation part adopts a 3+3 protocol design and consists of 5 cohorts. Based on the data obtained from the escalation study, selected cohorts will be expanded to further investigate the safety and efficacy of the study drug. The escalation part consists of a single-dose cycle (Cycle 0) followed by multiple-dose cycles (Cycle 1 and above). Subjects will be assessed for safety and efficacy outcomes at pre-specified time points.

Objective Response Rate (ORR)Tumor assessment every 6 weeks (+/- 7 days) until disease progression, expected follow-up period 6 months

n tumor treatment, the proportion of patients whose tumor volume has shrunk to a predetermined value and can be maintained for a certain period of time. It includes the proportion of patients with complete remission (CR) and partial remission (PR) to the total number of evaluable cases.

Duration Of Response (DOR)Tumor assessment every 6 weeks (+/- 7 days) until disease progression, expected follow-up period 6 months

The time from response to progression/death

Clinical Benefit Response (CBR)Tumor assessment every 6 weeks (+/- 7 days) until disease progression, expected follow-up period 6 months

The total percentage of patients who achieved a complete response, partial response, or had stable disease for 6 months or more.

Area Under the plasma drug concentration-time Curve (AUC)Blood samples will be collected at pre-specified time points in Cycles 0, 1 and 2 (Cycle 0 is 3 days, Cycles 1&2 each is 21 days)

Characterize the single-dose and multiple-dose plasma concentration of ILB2109

1-Year OSTumor assessment every 6 weeks (+/- 7 days) until disease progression, expected follow-up period 6 months

Maximum Plasma Concentration (Cmax)Blood samples will be collected at pre-specified time points in Cycles 0, 1 and 2 (Cycle 0 is 3 days, Cycles 1&2 each is 21 days)

Characterize the single-dose and multiple-dose plasma concentration of ILB2109

Overall Survival (OS)Tumor assessment every 6 weeks (+/- 7 days) until disease progression, expected follow-up period 6 months
