Trial Details

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.

    • Serum albumin ≥2.5 g/dL
    • Creatinine clearance ≥60 mL/min (calculated according to Cockcroft Gault formula)
    • Activated partial thromboplastin time and international normalized ratio ≤1.5 × ULN, except for patients receiving anticoagulant therapy, who must have international normalized ratio within therapeutic range as deemed appropriate by the investigator
  5. Female patients of childbearing potential must agree to use a highly effective form of contraception and not donate, or retrieve for their own use, ova from the time of screening and throughout the study period, and for at least 6 months after the last dose of study drug. Male patients must agree to use a highly effective form of contraception and not freeze or donate sperm from the time of screening and throughout the study period, and for at least 6 months after the last dose of study drug.
  6. Life expectancy of ≥3 months
  7. Able and willing to comply with protocol visits and procedures
  8. For NSCLC patients:
    • Have a histologically or cytologically confirmed diagnosis of locally advanced or metastatic NSCLC not amenable to curative surgery or radiation
    • Have a documentation of an EGFR-activating mutation (exon 19 deletion or L858R) detected from tumor tissue at diagnosis or thereafter. Participants who have this EGFR mutation detected from blood sample may be eligible on a case-by-case basis after discussion with the sponsor.
    • Have documentation of disease progression on or after, or are intolerant to most recent treatment regimen for locally advanced or metastatic disease. Participants must have received all of the following:
      • Prior treatment with a regimen containing a 3rd-generation EGFR TKI (e.g., osimertinib). Patients receiving a 3rd-generation EGFR TKI at the time of signing informed consent should continue to take the EGFR TKI until 5 days prior to Cycle 1 Day 1
      • Systemic therapy with at least 1 platinum-based chemotherapy regimen
      • Participants in the US must have also received prior treatment with an anti-PD-(L)1 antibody, unless they have high-risk factors indicating preferable avoidance of anti-PD-(L)1 therapy (e.g., intolerance or lack of efficacy is anticipated) Note: Patients who received platinum-based chemotherapy concurrently with anti-PD-(L)1 antibody as one regimen are eligible.

      • For BC patients:

    • Have a histologically or cytologically confirmed diagnosis of unresectable locally advanced or metastatic HR-positive and HER2-negative (IHC 0, 1+, 2+/ISH-) BC (per American Society of Clinical Oncology-College of American Pathologists [ASCO-CAP] guidelines)
    • Have documentation of disease progression on or after, or were intolerant to at least 1 prior line of endocrine therapy in combination with a CDK4/6 inhibitor
    • Have received 0-4 lines of chemotherapy regimens (including ADCs) for locally advanced or metastatic disease

      • Note 1: Prior treatments with PI3K inhibitors, mTOR inhibitors, AKT inhibitors, and PARP inhibitors are allowed.

      Note 2: If a patient develops disease relapse/progression during or within 6 months after the end of the (neo-)adjuvant therapy, or radical radiotherapy and chemotherapy, the treatment regimen will be counted as one line of treatment for locally advanced or metastatic disease, for the purpose of this inclusion criteria.

  9. Have at least 1 measurable tumor lesion according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1
  10. Willing to provide archival or fresh tumor tissue samples for assessment of HER3 expression level. Patients who are not able to provide tumor samples or have inadequate samples may be eligible after discussion with the sponsor.

    11. Exclusion Criteria

    Patients who meet any of the following criteria will be disqualified from entering the study:

  11. Prior treatment with an agent targeting HER3 (including antibody, ADC, chimeric antigen receptor T cell [CAR-T], and other drugs)
