Recruiting Phase 1

A Study of HLX18 vs. OPDIVO® in Multiple Resected Solid Tumors

About this study

This is a multicenter, randomized, double-blind, parallel-controlled phase I clinical study to evaluate the similarity in PK profile, efficacy, safety and immunogenicity of HLX18 and OPDIVO® in patients with resected esophageal or gastroesophageal junction cancer (EC/GEJC), melanoma (MEL), or urothelial carcinoma (UC).

Condition
Esophageal and/or Cardia Cancer, Melanoma, Urothelial Carcinoma (UC)
Tested
HLX18, OPDIVO®
Sponsor
Shanghai Henlius Biotech

Inclusion 15

  • Minimum age: 18 years
  • Maximum age: 70 years
  • Study condition: Esophageal and/or Cardia Cancer, Melanoma, Urothelial Carcinoma (UC)
  • Participants must have signed and dated an IRB/IEC approved written informed consent form.
  • Aged 18 to 70 years at the time of signing the ICF.
  • 18 kg/m² ≤ BMI ≤ 30 kg/m² and 50 kg ≤ body weight ≤ 85 kg.
  • Histologically confirmed solid tumors (EC/GEJC, Melanoma, or UC) status post R0 resection.
  • For EC/GEJC: residual pathologic disease (non-pCR) following neoadjuvant chemoradiotherapy and R0 resection.
  • For Melanoma: Stage IIB-IV after complete surgical resection with documented negative margins.
  • For UC: High-risk muscle-invasive urothelial carcinoma (MIUC) following radical resection (R0).
  • Documented disease-free status (no recurrence) by imaging and physical exam within 4 weeks prior to randomization.
  • Adequate recovery from prior surgery or systemic therapy.
  • ECOG Performance Status of 0.
  • Adequate organ function.
  • Agreement to use effective contraception (negative pregnancy test for WOCBP).

Exclusion 16

  • History of illicit drug use or alcohol abuse within 12 months prior to randomization.
  • Tumor-specific exclusions: cervical esophageal cancer, Stage IV EC/GEJC, or ocular melanoma.
  • UC-specific surgical exclusions: status post partial cystectomy or partial nephrectomy.
  • EC/GEJC treatment violations: failure to receive mandatory preoperative concurrent CRT (mono-therapy is ineligible).
  • Prior treatment with nivolumab or any other immune checkpoint inhibitors (PD-1, PD-L1, CTLA-4).
  • Other primary active malignancies within 5 years or history of organ/bone marrow transplantation.
  • Significant cardiovascular disease (MI, cerebrovascular disease) or unstable arrhythmia (QTc \> 450ms/470ms) within 6 months.
  • Chronic heart failure (NYHA Class III-IV) or LVEF \< 50% at screening.
  • Presence of interstitial pneumonia, pneumonitis, or severe lung function abnormalities.
  • Active autoimmune disease requiring systemic immunosuppressive therapy.
  • Known HIV infection, active Hepatitis B/C, or active pulmonary tuberculosis.
  • Peripheral neuropathy ≥ Grade 2 or history of carcinomatosis meningitis.
  • Use of systemic corticosteroids (\>10 mg/day prednisone equivalent), immunosuppressants, or live vaccines within 28 days.
  • Recent or planned participation in other investigational drug, device, or surgical studies.
  • Severe allergic reactions to monoclonal antibodies or any condition deemed unsuitable by the investigator.
  • The investigator has a clear reason to believe that participation in this study would be detrimental to the participant.
