A Phase I Study of the Safety, Pharmacokinetic and Pharmacodynamic Properties of Orally Administered APG-2449 in Patients With Advanced Solid Tumors
APG-2449 is a novel, orally active, multi-targeted tyrosine kinase inhibitor, which inhibits FAK, ALK, and ROS1 with nanomolar potencies. In preclinical studies, APG-2449 demonstrated potent antiproliferative activity in various cancer cell lines as a single agent. In combination treatment, APG-2449 enhanced anti-proliferative activities of several chemotherapeutic and targeted agents. It is indicated that APG-2449 may have a broad therapeutic potential for the treatment of human cancer as a single agent and in combination with other classes of anticancer drugs. APG-2449 is intended for the treatment of patients with advanced solid tumors. Upon completion of the Phase 1 dose escalation study to establish the maximum tolerated dose (MTD), dose-limiting toxicities (DLTs), and/or recommended phase 2 dose (RP2D), several phase Ib/II studies will be implemented accordingly.
• Dose exploration stage: non-small cell lung cancer diagnosed by histology and/or cytology and positive for ALK/ROS1 gene fusion (molecular diagnosis confirmed by the investigator) and malignant pleural mesothelioma, esophageal cancer and ovarian cancer. Kind of patients with advanced tumors.
• Expansion stage: cohort one, Patients with non-small cell lung cancer who have progressed or are not tolerated on second-generation ALK TKI therapy or any ROS1 TKI therapy treatment ; cohort two, ALK/ROS1 fusion gene positive without TKI treatment Patients with non-small cell lung cancer. The molecular diagnosis results of the above patients can be confirmed by the investigator.Cohort 3, patients with non-small cell lung cancer who have progressed or are intolerant to treatment with third-generation ALK inhibitors or second-generation ALK inhibitors, and whose pFAK expression value is greater than or equal to 70.

⁃ Men, women of childbearing age (postmenopausal women must have been menopausal for at least 12 months before they can be considered infertile) and their partners voluntarily take the study drug for at least 30 days after signing the informed consent form and taking the study drug as deemed effective by the investigator Contraceptive measures
⁃ Ability to understand and willingness to sign a written informed consent form
⁃ Subjects must be willing and able to complete the research procedures and follow-up inspections.
⁃ Subjects are required to provide fresh (for recurrent subjects only) or archived tumor tissue samples from within 28 days prior to treatment. If none of these specimens are available, they may be included after consultation with the sponsor.
⁃ Subjects should provide fresh or archived tumor tissue specimens within 28 days prior to treatment.
