About

This is a phase Ib, open-label, dose-escalation and expansion study to evaluate the safety, tolerability, pharmacokinetics and anti-tumor activity of KN026 combined with KN046 in subjects with advanced HER2 positive solid tumors.

Full description

The study is composed of 2 stages. Stage 1 consists of dose escalation cohorts for determining the maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D). Part 2 consists of 4 tumor type expansion cohorts for expanding the information on clinical safety, clinical pharmacokinetics and antitumor activity in HER2 positive patients.

KN026 combined with KN046
Experimental group
Description:
KN026 is an anti-HER2 bispecific antibody that can simultaneously bind two non-overlapping epitopes of HER2, leading to a dual HER2 signal blockade. KN046 is a PD-L1 - CTLA-4 bispecific antibody.
