Capmatinib Plus Trametinib for the Treatment of Metastatic Non-small Cell Lung Cancer With MET Exon 14 Skipping Mutation


Brief Summary

This phase I/Ib trial studies the side effects and best doses of capmatinib plus trametinib when given together for the treatment of patients with MET exon 14 skipping mutation non-small cell lung cancer that has spread to other places in the body (metastatic). Capmatinib is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal protein that signals cancer cells to multiply. This helps slow or stop the spread of cancer cells. Trametinib is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal protein that signals cancer cells to multiply. This helps stop the spread of cancer cells. Capmatinib and trametinib are "targeted therapies." These targeted therapies work by detecting and targeting a mutation in the MET gene. Giving Capmatinib and trametinib may kill more tumor cells in patients with metastatic non-small cell lung cancer.

  • Alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase (SGPT)) =< 3 X institutional upper limit of normal if no known liver metastases.
  • Alkaline phosphatase (ALP) =< 5.0 X institutional upper limit of normal.
  • Creatinine =< 1.5 x within institutional upper limit of normal.

  • Asymptomatic serum amylase =< grade 2.
    • Asymptomatic serum amylase increase grade 1 and 2 are allowed if at the beginning of the study is confirmed to have no signs and/or symptoms suggesting pancreatitis or pancreatic injury (e.g., elevated P-amylase, abnormal imaging findings of pancreas, etc.)
  • Serum lipase =< upper limits of normal (ULN).
  • Ability to understand a written informed consent document, and the willingness to sign it.
  • For participants with evidence of chronic hepatitis B virus (HBV) infection, the HBV viral load must be undetectable on suppressive therapy, if indicated.
  • Individuals with a history of hepatitis C virus (HCV) infection must have been treated and cured or currently be on treatment with an undetectable HCV viral load.
  • Individuals with treated brain metastases are eligible if follow-up brain imaging (within 1 month prior to first dose) after central nervous system (CNS)-directed therapy shows no evidence of progression and not on steroids.
  • Individuals with a prior or concurrent malignancy are eligible for this trial as long as they are not on active treatment and no active disease is present, and whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen. Exceptions: thyroid hormone replacement is allowed and adjuvant hormonal therapy for breast cancer is allowed.
  • Women of child-bearing potential and men with partners of child-bearing potential must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation, and for 16 weeks after last administration of study treatment. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately. Men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and 16 weeks after last administration of study treatment.

Exclusion Criteria:

  • Known activating mutations or oncogenic fusions in EGFR, KRAS g12c, ALK, ROS1, NTRK, BRAF V600E, or RET.
  • For Phase I patients enrolling into dose levels 1 or -1, intolerability of prior treatment with capmatinib 300 mg BID requiring dose reduction or permanent discontinuation is exclusionary.
  • For Phase I patients enrolling into dose level 2 or 3, intolerability of prior treatment with capmatinib 400 mg BID requiring dose reduction or permanent discontinuation is exclusionary.
  • Phase Ib patients enrolling into the dose expansion cohort must have previously tolerated the RP2D of capmatinib if they have received prior capmatinib treatment.
  • Pregnant women are excluded from this study because capmatinib and trametinib are tyrosine kinase inhibitors (TKIs) with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with capmatinib and trametinib, breastfeeding should be discontinued if the mother is treated with capmatinib and trametinib.
