Ceritinib + Trametinib in Patients With Advanced ALK-Positive Non-Small Cell Lung Cancer (NSCLC)

A Phase I/II Study of Ceritinib + Trametinib in Patients With Advanced ALK-Positive Non-Small Cell Lung Cancer (NSCLC)

This is a phase I/II study of ceritinib and trametinib in Stage IIIB or IV anaplastic lymphoma kinase (ALK) rearranged non-small cell lung cancer (NSCLC). The Phase I portion will investigate the safety and tolerability of the combination of ceritinib and trametinib in ALK or ROS-1 rearranged NSCLC. The Phase II portion will investigate the clinical efficiency of the combination of ceritinib and trametinib in 3 single arm cohorts: ALKi (ALK inhibitor) naïve patients; post-crizotinib progressed disease (PD) patients; and PD second line ALK tyrosine kinase inhibitor (TKI) patients.

This was intended to be a phase I/II study of ceritinib and trametinib in Stage IIIB or IV ALK rearranged NSCLC.

The phase I portion is a standard 3+3 dose escalation study starting at dose level 1 and will be open to any patient with ALK-rearranged, or ROS-1 rearranged NSCLC.

The study was terminated before Phase II was initiated. The study did not open Phase II for enrollment into the planned cohorts:

• Cohort A (ALKi Naïve)
• Cohort B (Post-crizotinib PD)
• Cohort C (PD second line ALK TKI (e.g., alectinib, ceritinib, PF-06463922 or - AP21163)

Only participants in Phase 1 were enrolled.

Patients may continue treatment for up to 24 months from the time of study entry, and will receive 12 months of follow-up following completion of the drugs.

   • Female sterilization (have had surgical bilateral oophorectomy with or without 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.

     3. Barrier methods of contraception: Condom or Occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/vaginal suppository.

   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 prior to screening.

10. Sexually active males unless they use a condom during intercourse while taking drug and for 3 months after the last dose of study treatment. Male patients for 3 months should not father a child in this period. A condom is required to be used also by vasectomized men in order to prevent delivery of the drug via seminal fluid.
