A Study of YL202 in Patients With Locally Advanced or Metastatic Non-small Cell Lung Cancer and Breast Cancer

Not Applicable

Active, not recruiting

• Conditions: Non Small Cell Lung Cancer; Breast Cancer
• Interventions: Drug: YL202

• Registration Number: NCT05653752
• Lead Sponsor: MediLink Therapeutics (Suzhou) Co., Ltd.

Brief Summary

This is a phase 1, multicenter, open-label, first-in-human study of YL202 conducted in the United States and China.

The study will evaluate the safety and tolerability of YL202 in patients with locally advanced or metastatic epidermal growth factor receptor (EGFR)-mutated NSCLC or hormone receptor (HR)-positive and HER2-negative BC, which have been heavily treated by standard treatment.

Arm && Interventions

Group	Intervention	Description
YL202 Dose escalation	YL202	YL202 will be administrated intravenously (IV) per dose level in which the patients are assigned.

Primary Outcome Measures

Name	Time	Method
Evaluate the occurrence of DLTs during the first cycle	At the end of Cycle 1 (each cycle is 21 days)
Evaluate the AEs as characterized by type, frequency, severity, timing, seriousness and relationship to study treatment	By the global end of trial date, approximately within 36 months

Secondary Outcome Measures

Name	Time	Method
Characterize the PK parameter AUC	Approximately within 36 months
Characterize the PK parameter Cmax	Approximately within 36 months
Characterize the PK parameter Ctrough	Approximately within 36 months
Characterize the PK parameter CL	Approximately within 36 months
Characterize the PK parameter Vd	Approximately within 36 months
Characterize the PK parameter t1/2	Approximately within 36 months
Assess the incidence of anti-YL202 antibodies	Approximately within 36 months
Evaluate the objective response rate (ORR)	Approximately within 36 months	ORR: defined as the proportion of patients who achieved a best overall response of complete response (CR) or partial response (PR).
Evaluate the disease control rate (DCR)	Approximately within 36 months	DCR: defined as the proportion of patients who achieved a best overall response of CR, PR or stable disease (SD).
Evaluate the best tumor response	Approximately within 36 months	Best tumor response: defined as the maximum percentage change in the sum of longest dimensions of measurable lesion(s) at any time during the study.
