A Phase 1/2, Open-label, Multicenter, First-in-Human Study to Evaluate the Safety, Tolerability, Pharmacokinetics and Anti-tumor Activity of YH32367 in Patients With HER2-Positive Locally Advanced or Metastatic Solid Tumors
Yuhan Corporation
Summary
This first-in-human study will be counducted to evaluate the safety, tolerability, pharmacokinetics (PK) and anti-tumor activity of YH32367 in Patients with HER2-Positive Locally Advanced or Metastatic Solid Tumors.
Description
YH32367, a novel HER2/4-1BB bispecific antibody (BsAb), simultaneously targets HER2 and h4-1BB and binds to both targets. YH32367 exhibits a strong 4-1BB signal activation as well as blocking of HER2 signaling in HER2-expressing tumor cells. YH32367 stimulates IFN-γ secretion from T cells and thereby induces tumor cells lysis. This is a Phase 1/2, open-label, multicenter, first-in-human study of YH32367. This 2-part study will include both a Dose Escalation part, to identify the Maximum Tolerated Dose (MTD) and/or two dose levels for RP2D selection, and a Dose Expansion part, to determine RP2…

Cohort 1: Pathologically confirmed HER2-positive biliary tract cancer 2.

Interventions
- DrugYH32367
Dose Escalation Part: 8 Cohorts. In this part, approximately 30 patients will be enrolled and patients are assigned to receive YH32367 at a starting dose and the dose being escalated/de-escalated in adjacent dose cohorts will be up to Dose level 8. Dose Expansion Part: 2 Cohorts(Cohort 1: Biliary tract cancer, Cohort 2: Solid tumors). The part will consist of multiple cohorts in patients who were treated with at least 1 prior gemcitabine- and/or cisplatin-based therapy, HER2 positive biliary tract cancer(Cohort 1); in patients who were treated with all available standard therapies and have no available options, HER2 positive solid tumor malignancies other than breast and gastric or gastroesophageal junction adenocarcinoma and biliary tract cancer(Cohort 2). Each cohort will enroll approximately 75 and 40 patients, respectively.
