Study Description

Brief Summary:

This is an open-label, phase 1 dose-escalation study of KN026 in subjects with HER2 positive advanced breast and Gastric Cancer. The standard "3 + 3" design was used for dose escalation. There are 3 proposed dose levels which are 10, 15, and 20 mg/kg, but dosing interval may be adjusted during the study (such as QW, OR Q2W, OR Q3W) based on emerging data from this trial and/or from phase 1 trial of KN026 in other country. Dose escalation will continue until the maximum tolerated dose (MTD) is reached or if MTD is not found, dose escalation will continue until the MAD of 20 mg / kg is reached.

3. Time of Maximum observed serum concentration (Tmax) of KN026 [ Time Frame: Throughout the duration of the study; up to 84 days ]
4. Frequency and titer of anti-KN026 antibody [ Time Frame: Throughout the duration of the study; up to 2 years ]
5. The proportion of patients with an objective response (partial response or complete response) as defined by RECIST 1.1 criteria [ Time Frame: Throughout the duration of the study; up to 2 years ]
6. Progression free survival according to RECIST 1.1 criteria [ Time Frame: Throughout the duration of the study; up to 2 years ]
