Clinical trial: TORC1/2 Inhibitor INK128 and EGFR Inhibitor AZD9291 in Treating Patients With Advanced EGFR Mutation Positive Non-small Cell Lung Cancer After Progression on a Previous EGFR Tyrosine Kinase Inhibitor

Summary: This phase I trial studies the side effects and best dose of transducer of regulated CREB activity 1/2 (TORC1/2) inhibitor INK128 when given together with epidermal growth factor receptor (EGFR) inhibitor AZD9291in treating patients with advanced EGFR mutation positive non-small cell lung cancer that has spread to other places in the body (advanced) and has progressed after treatment with an EGFR tyrosine kinase inhibitor. TORC1/2 inhibitor INK128 and EGFR inhibitor AZD9291 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Detailed description: PRIMARY OBJECTIVES:
  I. To determine the safety and recommended phase II dose (RP2D) of MLN0128 (TORC1/2 inhibitor INK128) in combination with AZD9291 (EGFR inhibitor AZD9291) in patients with advanced epidermal growth factor receptor mutation positive (EGFRm) non-small cell lung cancer (NSCLC). (Dose escalation phase) II. To evaluate the safety and preliminary efficacy of MLN0128 in combination with AZD9291 in patients with advanced EGFRm NSCLC that is negative for the resistance mutation T790M (T790M negative [-]). (Dose expansion phase)
  SECONDARY OBJECTIVES:
  I. To evaluate pharmacokinetic profiles of MLN0128 in combination with AZD9291. II. To evaluate the response rate, disease control rate and progression free survival of the combination.
  III. To explore biomarkers of response and resistance to the combination by studying baseline biopsies, resistance biopsies, and serial plasma deoxyribonucleic acid (DNA) specimens.
  OUTLINE: This is a dose-escalation study of TORC1/2 inhibitor INK128.
  Patients receive TORC1/2 inhibitor INK128 orally (PO) once daily (QD) on days 1, 3, 5, 8, 10, 12, 15, 17, 19, 22, 24, and 26 (day 1 is omitted in course 1). Patients also receive EGFR inhibitor AZD9291 PO QD on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
  After completion of study treatment, patients are followed up at 30 days, and then every 8 weeks thereafter.

  -  DOSE EXPANSION PHASE:
  -  Progressive disease on one prior EGFR TKI (erlotinib or gefitinib or afatinib), which must be the last prior therapy and tumor must be EGFR negative for T790M based on tissue collected after progression on the prior EGFR TKI and T790M status confirmed by central testing prior to registration
  -  Prior therapy with 3rd generation TKI including CO-1686, AZD9291 is not permissible
  -  DOSE ESCALATION AND DOSE EXPANSION PHASE:
  -  A minimum of 7 days must have elapsed from the last dose of the prior EGFR inhibitor and resolution of any drug-related toxicity to =< grade 2 except for alopecia
  -  Prior chemotherapy, radiation therapy and surgery are permissible as follows:
  -  Chemotherapy- a minimum of 21 days must have elapsed from the last dose and resolution of toxicity excluding =< grade 2 peripheral neuropathy or alopecia
  -  Surgery- a minimum of 21 days must have elapsed following major surgery and complete wound healing must have occurred
  -  Radiation- minimum of 14 days must have elapsed following radiation therapy and resolution of all radiation induced toxicity
  -  Ability to understand and the willingness to sign a written informed consent document
  -  Available for long-term follow-up of their disease after treatment
  Exclusion Criteria:
