Open Actively Recruiting

A Study to Investigate the Safety, Pharmacokinetics, Pharmacodynamics, and Preliminary Efficacy of KD033 in Subjects With Metastatic or Locally Advanced Solid Tumors.

About

Brief Summary

This is a First-in-Human, open-label, sequential dose-escalation and dose-expansion study of KD033 in adult subjects with advanced or metastatic solid tumors. The main purpose of this study is to test KD033 at different dose levels to see if it is safe and well tolerated when given once every 2 weeks. Additional purposes of the study are to find out whether the study drug has anti-cancer effects and how the study drug is processed by the body.

  • Eastern Cooperative Oncology Group Performance Status (ECOG PS) score ≤ 1.
  • Adequate organ and bone marrow functions.
  • All toxicities related to prior radiotherapy, chemotherapy, or surgical procedure must have recovered to baseline or Grade ≤ 1 based on NCI-CTCAE v5.0 except alopecia (any grade), Grade 2 peripheral neuropathy and adverse events that are clinically non significant or stable on supportive care.
  • All subjects, male and female, who are not surgically sterilized or postmenopausal must agree to use "highly effective methods of contraception" during the study and for at least 60 days after the last dose of KD033.

Exclusion Criteria:

  • Use of immunotherapy, biological therapy, cytokine therapy < 21 days prior to the first dose of study drug.
  • Use of immunomodulating agents < 21 days prior to the first dose of study drug.
  • Use of chemotherapy and approved tyrosine kinase inhibitor (TKI) therapy < 14 days prior to the first dose of study drug.
  • Anti PD-L1 or anti PD-1 therapy < 6 weeks prior to the first dose of study drug.

  • Systemic therapy with immunosuppressive agents including corticosteroids within 14 days before the start of trial treatment.
  • Rapidly progressive disease which, in the opinion of Investigator, may predispose to inability to tolerate treatment or trial procedure.

  • Has a paraneoplastic syndrome of autoimmune nature.
  • History of interstitial lung disease or severe obstructive pulmonary disease.
  • Clinically significant cardiovascular/cerebrovascular disease.
  • QTc(F) interval > 450 ms for men or > 470 ms for women)
