  • Publication number: 20220054475
    Abstract: The present invention relates to a chemo combination therapy regimen to treat cancer. More specifically, the present invention relates to a novel chemo combination therapy regimen which relates to the combination of compound AL3818 (anlotinib, catequentinib) or its pharmaceutically acceptable salts with standard platinum-based and other chemotherapy agents or immunotherapy agents. The combination of these agents should be able to provide higher efficacy than employing any agent individually.
