NCT06057922

Brief Summary

This is A Multicenter, Open-Label, Phase 1/2 Study to Evaluate the Safety, Efficacy, and Pharmacokinetics of YL201 in Patients with Selected Advanced Solid Tumors. The study will include 2 parts: Phase 1 dose expansion stage (Part 1) followed by a Phase 2 stage with expanded sample size (Part 2). Part 1 will estimate the RP2D in dose expansion cohorts of patients with not linited to non-small cell lung cancer (NSCLC), small cell lung cancer (SCLC), nasopharyngeal carcinoma (NPC), esophageal squamous cell carcinoma (ESCC), metastatic castration-resistant prostate cancer (mCRPC), head and neck squamous cell carcinoma (HNSCC), sarcoma, ductal adenocarcinoma of pancreas (PDAC), hepatocellular carcinoma (HCC), biliary tract cancer (BTC), etc.. Part 2 will include patients with selected advanced solid tumor types enrolled at the RP2D to further assess the efficacy and safety of YL201.

Outcome Measures

Primary Outcomes (3)

  • 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

  • Evaluate the objective response rate (ORR) for patients with solid tumors which assessed using RECIST version 1.1

    ORR: defined as the proportion of patients who achieved a best overall response of complete response (CR) or partial response (PR).

    Time Frame: Approximately within 36 months

  • Evaluate the prostate-specific antigen (PSA) response rate for patients with prostate cancer

    PSA response rate: defined as the proportion of patients who achieved a ≥50% decrease in PSA from baseline

    Time Frame: Approximately within 36 months

Secondary Outcomes (16)

  • 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

  • +11 more secondary outcomes

Study Arms (2)

Phase 1 dose expansion stage

EXPERIMENTAL

Patients will be treated with YL201 intravenous (IV) infusion once every 3 weeks (Q3W) as a cycle; and at dose levels of 1.0 mg/kg and 1.2 mg/kg administered on Days 1 and 8 of each Q3W treatment cycle.

Drug: YL201 for Injection

Phase 2 stage with expanded sample size

EXPERIMENTAL

Patients will be treated with YL201 intravenous (IV) infusion at PR2D once every 3 weeks (Q3W) as a cycle; and at dose levels of 1.0 mg/kg and 1.2 mg/kg administered on Days 1 and 8 of each Q3W treatment cycle.

Drug: YL201 for Injection

Interventions

Patients will be treated with YL201 intravenous (IV) infusion once every 3 weeks (Q3W) as a cycle; and at dose levels of 1.0 mg/kg and 1.2 mg/kg administered on Days 1 and 8 of each Q3W treatment cycle.
