Study Details

Study Description

Brief Summary

This is a phase II single-arm open label trial to evaluate the intracranial efficacy of capmatinib in advanced stage NSCLC with asymptomatic BM with positive MET amplification or METΔex14 detected on cfDNA.

Condition or Disease Intervention/Treatment Phase
Phase 2

Detailed Description

This will be a phase II single-arm open label trial of capmatinib at a dose of 400 mg orally twice daily in advanced stage NSCLC with asymptomatic BM with positive MET amplification or METΔex14 detected on cfDNA. This trial will evaluate the intracranial efficacy of capmatinib in cfDNA MET amplification or mutation positive NSCLC. Potentially eligible patients will undergo prescreening with Predicine's cfDNA assay to identify cfDNA MET amplification or mutation positive NSCLC patients. Radiographic assessments for cranial and extracranial disease response will occur every 8 weeks. Capmatinib will be given until disease progression or intolerability of treatment. A two-stage single arm design will be used to establish whether the proportion of responses is sufficiently high to warrant further testing and to allow stopping for futility at the first stage.

    28. Pregnant or nursing (lactating) women.

    29. Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, unless they are using highly effective methods of contraception during dosing and for 7 days after stopping treatment. Highly effective contraception methods include:

    • Total abstinence (when this is in line with the preferred and usual lifestyle of the subject. Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception

    • Female sterilization (have had surgical bilateral oophorectomy with or without hysterectomy) total hysterectomy, or tubal ligation at least six weeks before taking study treatment. In case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment

    • Male sterilization (at least 6 months prior to screening). For female subjects on the study the vasectomized male partner should be the sole partner for that subject

    • Use of oral, injected or implanted hormonal methods of contraception or placement of an intrauterine device (IUD) or intrauterine system (IUS), or other forms of hormonal contraception that have comparable efficacy (failure rate <1%), for example hormone vaginal ring or transdermal hormone contraception. In case of use of oral contraception women should have been stable on the same pill for a minimum of 3 months before taking study treatment.

    Women are considered post-menopausal and not of child bearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g., age appropriate, history of vasomotor symptoms) or have had surgical bilateral oophorectomy (with or without hysterectomy) or tubal ligation at least six weeks before study entry. In the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment is she considered not of child bearing potential

    1. Sexually active males unless they use a condom during intercourse while taking drug and for 7 days after stopping treatment and should not father a child in this period. A condom is required for all sexually active male to prevent them from fathering a child AND to prevent delivery of study treatment via seminal fluid to partner. In addition, male participants must not donate sperm for the time period specified above

    2. Patients who received live vaccines (e.g., intranasal influenza, measles, mumps, rubella, oral polio, BCG, yellow fever, varicella, TY21a typhoid vaccines and COVID 19 vaccines if a live COVID 19 vaccine becomes available) within 30 days prior to the first dose of IP.
