A Study of SIM0689 in Adult Participants With Locally Advanced or Metastatic Solid Tumors

18 augusti 2026 uppdaterad av: Jiangsu Simcere Pharmaceutical Co., Ltd.

Phase I First-in-Human, Open-label, Multicenter Study to Evaluate the Safety, Tolerability, Pharmacokinetics and Preliminary Antitumor Activity of SIM0689 in Adult Participants With Locally Advanced or Metastatic Solid Tumors

This study will evaluate the safety, of SIM0689 and how the body processes it, how it affects the body, and its early signs of activity against tumors when given alone to Adult Participants with Locally Advanced or Metastatic Solid Tumors. The study has a dose escalation part to find the highest dose that can be given safely, or recommended dose (RD) for SIM0689 when given alone, and a dose expansion part in subjects with specific tumor types treated with SIM0689 as a single agent at RD.

Beskrivning

Inclusion Criteria:

  • In dose-escalation cohorts (Part 1), histologically or cytologically documented advanced or metastatic solid tumor that is refractory/relapsed to standard therapies, or for which no effective standard therapy is available, or the subject refuses standard therapy.

  • Subjects must have at least one measurable lesion according to RECIST Version1.1.
  • Eastern Cooperative Oncology Group (ECOG) Performance Score of 0 or 1.
  • Adequate organ function.
  • Available archived tumor tissue sample to allow for correlative biomarker studies. If unavailable or unsuitable, the subject must consent and undergo fresh tumor biopsy.
  • Life expectancy ≥12 weeks.

  • Known hereditary or acquired predisposition to bleeding and thrombosis.
  • History of gastrointestinal perforation, gastrointestinal bleeding, fistula, or any life-threatening bleeding event within 6 months prior to enrollment.
  • Prior permanent discontinuation of PD-(L)1 and/or VEGF monoclonal antibody because of immune/anti-angiogenesis toxicities, or history of Grade ≥3 immune/anti-angiogenesis-related AEs
  • Known or suspected active autoimmune disease.
  • Patients with proteinuria at screening (Urine protein >2+ at screening, or 2+ urine protein accompanied by 24-h urine protein ≥1 g/24 h).
  • History of myocardial infarction or stroke within 6 months prior to enrollment.
