Study of the Safety, Tolerability, Pharmacokinetics, Immunogenicity and Antitumor Activity of KN046 in Subjects With Advanced Solid Tumors
May 20, 2018 updated by: Alphamab (Australia) Co Pty Ltd.
An Open-Label, Multi-center, Dose-Escalation Phase I Study to Evaluate Safety, Tolerability, Pharmacokinetics and Immunogenicity of KN046 in Subjects With Advanced Solid Tumors
This is an open-label, multicenter, dose-escalation phase I study to assess the safety, tolerability and preliminary efficacy of KN046 in participants with all advanced solid tumors who are not able to have current standard anti-tumor therapies.
The purpose of this study is to determine the maximum tolerated dose (MTD) or a biological effective dose (BED), to characterise the safety, pharmacokinetics (PK), immunogenicity, pharmacodynamics (PD) and anti-tumor activity of KN046 as a single agent in adult participants with advanced solid tumors

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number of participants with dose limiting toxicity (DLT)
Time Frame: During the first cycle (4 weeks) of treatment.
|
An DLT is defined as a ≥Grade 3 drug-related adverse event occurring within the first cycle (28 days) of dosing (excluding tumor flare causing local pain at sites of known or suspected tumor, localized rash, or a transient ≤Grade 3 infusion reaction) using National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE).
|
