2026年9月23日 更新者:Iksuda Therapeutics Ltd.

進行性HER2+固形腫瘍の参加者を対象に、HER2標的抗体薬物複合体(ADC)であるIKS014の安全性、忍容性、最大耐用量、予備抗腫瘍活性を判定するための第1相用量漸増試験

This study will evaluate the recommended dose for further clinical development, safety, tolerability, anti-tumor activity, immunogenicity, pharmacokinetics and pharmacodynamics of IKS014, a HER2 targeting antibody-drug conjugate, in patients with advanced solid tumors.

詳細な説明

The study will consist of 2 parts: dose-escalation (Part 1) and dose-expansion (Part 2). The dose-escalation part (Part 1) of the study is to evaluate the safety and tolerability of increasing dose levels of IKS014 to establish a recommended phase 2 dose (RP2D); and the dose-expansion part (Part 2) of the study is to further evaluate the safety, pharmacokinetics/pharmacodynamics, and efficacy of IKS014 at the RP2D.

  • Current evidence of ≥ Grade 2 keratitis or other corneal abnormality.

  • Evidence of a clinically significant (≥ Grade 2) abnormality on slit-lamp examination or other clinically significant ophthalmologic finding, as determined by an ophthalmologist.

  • Evidence of clinically significant (≥ Grade 2) confluent superficial keratitis, a corneal epithelial defect, a corneal ulcer, or stromal opacity.

  • Participant must not use contact lenses while participating in this study.

  • Central nervous system metastatic disease unless treated with definitive local therapy (surgical resection, stereotactic radiotherapy, or whole brain radiotherapy) and participant is clinically, radiologically and neurologically stable for at least 4 weeks prior to the first dose of study drug not on steroid therapy or are on a stable or decreasing dose of steroids for at least 7 days prior to first dose of study drug. Prophylactic anticonvulsant medications are allowed.

  • Active second malignancy or history of another malignancy within the last 2 years with the exception of:

    • Treated, non-melanoma skin cancers
    • Treated carcinoma in situ (CIS) (e.g., breast, cervix)
    • Controlled, superficial carcinoma of the urinary bladder
    • T1a or b carcinoma of the prostate treated according to local standard of care, with prostate specific antigen (PSA) within normal limits (WNL) for the institution
    • Papillary thyroid carcinoma Stage I treated surgically for cure
  • Clinically significant cardiovascular disease or condition

  • Clinically significant liver disease

  • Any other serious/active/uncontrolled infection, any infection requiring parenteral antibiotics, or unexplained fever > 38ºC within 2 weeks prior to first trial drug administration.

  • Any other serious, life-threatening, or unstable preexisting medical condition (aside from the underlying malignancy), including significant organ system dysfunction, or clinically significant laboratory abnormality(ies), which, in the opinion of the Investigator, would either compromise the participant's safety or interfere with obtaining informed consent, compliance with trial procedures, or evaluation of the safety of the trial drug.
