HY-0102 Monotherapy in Patients With Locally Advanced/Metastatic Solid Tumours

A Phase Ⅰ, Multi-center, Open-label, Single-arm, Dose Escalation, First-in-human Clinical Study of HY-0102 Monotherapy in Patients With Locally Advanced/Metastatic Solid Tumours

This is a Phase I, first-in-human trial to evaluate the Safety, Tolerability, Pharmacokinetics and Preliminary Antitumor Activity of HY-0102 administered intravenously (IV) once every two weeks in adult patients with locally advanced/metastatic malignant solid tumors.

Study Overview

• Status: Completed
• Conditions: Locally Advanced/Metastatic Solid Tumors
• Intervention / Treatment: Drug: HY-0102

Detailed Description

This is a Phase I, first-in-human trial to evaluate the Safety, Tolerability, Pharmacokinetics and Preliminary Antitumor Activity of HY-0102 administered intravenously (IV) once every two weeks in adult patients with locally advanced/metastatic malignant solid tumors (head and neck, liver, colorectal and lung cancers, etc).

Six dosing cohorts are planned with the dose of 0.03, 0.3, 1, 2, 4 and 10 mg/kg. The first two dose levels (0.03 and 0.3 mg/kg) will each enroll one patient using an accelerated escalation design that will convert to a 3+3 design upon the occurrence of one treatment-related Grade 2 toxicity occurring in the safety evaluation window following the first dose of treatment. After the initial two cohorts are completed, the study will use a standard 3+3 dose escalation design.

The number of enrolled patients is estimated to be up to 32. The dose limiting toxicity evaluation period will be the first 28 days (Cycle 1) and subsequent cycles will be 4 weeks in duration. Patients will receive the investigational drug on Day 1 of cycle 1 followed by 28 days of observation. HY-0102 will be administered IV once every two weeks for Cycle 2 and beyond.

6. ECOG performance status 0 or 1; Life expectancy ≥ 3 months.

7. Adequate hepatic function as evidenced by meeting all the following requirements:

   1. Total bilirubin ≤ 1.5 ×within institutional upper limit of normal (ULN); or ≤ 2.5 × institutional ULN for patients who have serum bilirubin increases due to underlying Gilbert's Syndrome or familial benign.
   2. Aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALP) ≤ 2.5 × ULN; AST or ALT ≤ 5 × ULN if liver metastases are present.
