GeoMETry-III: This phase III trial is trying to understand whether an oral targeted therapy (capmatinib) is able to control lung cancer better than standard chemotherapy (docetaxel) and is safe to use in patients with lung cancerA Phase III, Randomized, Controlled, Open-label, Multicenter, Global Study of Capmatinib Versus SoC Docetaxel Chemotherapy in Previously Treated Patients With EGFR wt, ALK Negative, Locally Advanced or Metastatic (Stage IIIB/IIIC or IV) NSCLC Harboring MET Exon 14 Skipping Mutation (METΔex14).

Clinical summary

Summary

Eligible patients will be randomised to receive 400mg oral capmatinib twice daily, or 75mg intravenous docetaxel on Day 1 of each 21-Day cycle.

Conditions

This trial is treating people with non-small cell lung cancer

Eligibility

Inclusion

  • Stage IIIB/IIIC (not amenable to surgery, radiation or multi modality therapy) or IV NSCLC (according to Version 8 of the American Joint Committee on Cancer (AJCC) Staging Manual) at the time of study entry.
  • Histologically or cytologically confirmed diagnosis of NSCLC that is:

    1. EGFR wt. Assessed as part of participant's standard of care by a validated test for EGFR mutations as per local guidelines. The EGFR wt status (for EGFR mutations that predict sensitivity to EGFR therapy, including, but not limited to exon 19 deletions and exon 21 L858R substitution mutations.
    2. AND ALK rearrangement negative. Assessed as part of participant's standard of care by a validated test.
    3. AND has METΔex14 mutation as determined by Novartis-designated central laboratory or by locally performed, tissue-based test, validated according to local regulation, from a Clinical Laboratory Improvement Amendments (CLIA)-certified US laboratory or an accredited local laboratory outside of the US. The positive METΔex14 mutation result as determined per local test must be documented in the participant's source documents and in the CRF prior to entering main screening.
  • Mandatory provision of a formalin-fixed, paraffin embedded tumor tissue sample (archival tumor block or slides, or a newly obtained tumor sample) with quality and quantity sufficient to allow assessment of METΔex14 mutation status (as defined in the study [laboratory manual]). This pertains to all participants, including those who have a METΔex14 mutation result from a local test. Tumor samples must contain at least 10% tumor content.

    6. Participants must have progressed on one or two prior lines of

  • Progressed on one or two prior lines of systemic therapy for advanced/metastatic disease (stage IIIB/IIIC [not candidates for surgery, radiation or multi modality therapy] or IV NSCLC) and must be docetaxel naïve and candidates for single agent chemotherapy (docetaxel). Treatment failure is defined as documented disease progression or intolerance to treatment., however participants must have progressed on or after the last therapy before study entry.
  • At least one measurable lesion as defined by RECIST 1.1
  • Adequate organ function
  • Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0 or 1.
  • Participants must have a life expectancy of at least 3 months.

Exclusion

  • Prior treatment with any MET inhibitor or HGF-targeting therapy.
  • Participants with symptomatic central nervous system (CNS) metastases who are neurologically unstable or have required increasing doses of steroids within the 2 weeks prior to study entry to manage CNS symptoms.
  • Participants with known druggable molecular alterations (such as ROS1and RET rearrangement, BRAF mutation, KRAS mutation, NTRK fusion, etc.) which might be a candidate for alternative targeted therapies.
  • Presence or history of interstitial lung disease or interstitial pneumonitis, including clinically significant radiation pneumonitis (i.e., affecting activities of daily living or requiring therapeutic intervention).
  • Substance abuse, active infection or other severe, acute, or chronic medical or psychotic conditions or laboratory abnormalities that in the opinion of the investigator may increase the risk associated with study participation

Other protocol-defined inclusion/exclusion criteria may apply.

Inclusion

  • Your cancer has spread to other parts of the body (metastatic) or has grown into nearby parts of the body (locally advanced).
  • You have had treatment but your cancer has gotten worse or has not responded to the treatment you have been given.

Exclusion

  • You have certain types of non-cancer medical conditions.
  • You have had certain treatments, surgical procedures or drugs.
