About

To assess:

  • efficacy of APL-101 as monotherapy for the treatment of NSCLC harboring MET Exon 14 skipping mutations, NSCLC harboring MET amplification, solid tumors harboring MET amplification, solid tumors harboring MET fusion, primary CNS tumors harboring MET alterations, solid tumors harboring wild-type MET with overexpression of HGF and MET
  • efficacy of APL-101 as an add-on therapy to EGFR inhibitor for the treatment of NSCLC harboring EGFR activating mutations and developed acquired resistance with MET amplification and disease progression after documented CR or PR with 1st line EGFR inhibitors (EGFR-I)

  3. Use or intended use of any other investigational product, including herbal medications, through Study Treatment Termination.

  4. Active uncontrolled systemic bacterial, viral, or fungal infection or clinically significant, active disease process, which in the opinion of the investigator makes the risk: benefit unfavorable for the participation of the trial.

  5. Life-threatening illness, significant organ system dysfunction or comorbid conditions, or other reasons that, in the investigator's opinion, could compromise the subject's safety or the integrity of the study outcomes, or interfere with the absorption or metabolism of APL-101.

Historical seropositive results consistent with active infection for hepatitis C virus (HCV) or hepatitis B virus (HBV) with high viral loads not actively managed with antiviral therapy and human immunodeficiency virus (HIV) positive subjects who are not clinically stable or controlled on their medication (asymptomatic subjects with CD4+ T-cell (CD4+) counts ≥ 350 cells/μL and have not had an opportunistic infection within the past 12 months prior to first dose of APL-101 would be eligible for study entry. If history is unclear, relevant test(s) at Screening will be required to confirm eligibility.

  9. Unable to swallow orally administered medication whole.

  13. Subjects who are unable or unwilling to discontinue excluded medications (drugs with known QTc risk and known strong cytochrome P450 [CYP]3A4 inducer and/or strong inhibitors) for at least 5 half-lives prior to first dose of study drug. Subjects may qualify if such medication(s) can be safely replaced with alternate medications with less risk of drug-drug interaction.

  14. Subjects with active COVID-19 infection.
