Overview
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.

Arms & Interventions
Phase 1 dose expansion stage
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.
Intervention: YL201 for Injection
Phase 2 stage with expanded sample size
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.
Intervention: YL201 for Injection
Outcomes
Primary Outcomes
Evaluate the prostate-specific antigen (PSA) response rate for patients with prostate cancer
Time Frame: Time Frame: Approximately within 36 months
PSA response rate: defined as the proportion of patients who achieved a ≥50% decrease in PSA from baseline
Evaluate the AEs as characterized by type, frequency, severity, timing, seriousness and relationship to study treatment
Time Frame: 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
Time Frame: Time Frame: 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).
Secondary Outcomes
- Characterize the PK parameter AUC(Approximately within 36 months)
- Characterize the PK parameter Vd(Approximately within 36 months)
- Characterize the PK parameter t1/2(Approximately within 36 months)
- Characterize the PK parameter CL(Approximately within 36 months)
- Evaluate the time to response (TTR) for patients assessed using RECIST version 1.1(Approximately within 36 months)
- Evaluate the overall survival (OS) for patients(Approximately within 36 months)
- Evaluate the duration of response (DoR) for patients assessed using RECIST version 1.1(DoR: defined as the time interval from the date of the first documentation of objective response (CR or PR) to the date of the first documentation of PD. DoR will be assessed for patients with a response (CR or PR) only.)

- Characterize the PK parameter Cmax(Approximately within 36 months)
- Evaluate the disease control rate (DCR) for patients assessed using RECIST version 1.1(DCR: defined as the proportion of patients who achieved a best overall response of CR, PR or stable disease (SD).)
- Evaluate the radiographic progression-free survival (rPFS) for patients with prostate cancer(Approximately within 36 months)
- Evaluate the PSA duration of response (PDoR) for patients with prostate cancer(Approximately within 36 months)
