Details and patient eligibility


This open-label, non-randomized, multicenter, Phase 1/2 study will evaluate the safety and efficacy of alectinib in participants with non-small cell lung cancer who have ALK mutation and failed crizotinib treatment. In Part 1, cohorts of participants will receive escalating doses of alectinib orally twice daily. In Part 2, participants will receive the recommended phase 2 dose (RP2D) of alectinib as determined in Part 1. Treatment will continue in Part 1 and Part 2 on the same dose until disease progression. In Part 3, following disease progression, participants without epidermal growth factor receptor (EGFR) mutation will be offered continued treatment with alectinib, participants with EGFR mutations will be offered a combination of alectinib and erlotinib.

Inclusion criteria

  • Locally advanced or metastatic non-small cell lung cancer (stage IIIB or IV by American Joint Committee on Cancer [AJCC])
  • Eastern Cooperative Oncology Group (ECOG) performance status 0-2
  • Documented ALK rearrangement based on Food and Drug Administration (FDA)-approved test
  • Prior treatment with crizotinib and progression according to response evaluation criteria in solid tumors version 1.1 (RECIST v1.1) criteria. Participants had to have a minimum 1-week wash-out period between the last dose of crizotinib and the first dose of study treatment. Participants can either be chemotherapy-naïve or have received at least one line of platinum-based chemotherapy
  • Adequate hematologic, hepatic, and renal function
  • Participants with brain or leptomeningeal metastases are allowed if protocol defined criteria are met
  • Measurable disease according to RECIST v1.1 prior to administration of first dose of study drug

Exclusion criteria

  • Receipt of any other ALK inhibitors in addition to crizotinib
  • Receipt of any prior cytotoxic chemotherapy for ALK-positive NSCLC within 4 weeks prior to the first dose of study drug
  • Participants who received crizotinib or any other tyrosine kinase inhibitors need to have a minimum 1-week washout period before the first dose of study drug
  • Active or uncontrolled infectious diseases requiring treatment
  • National Cancer Institute Common Terminology Criteria for Adverse Events version 4.03 (NCI CTCAE v4.03) Grade 3 or higher toxicities due to prior therapy that have not shown improvement and are considered to interfere with current study medication
  • History of organ transplant
  • Co-administration of anti-cancer therapies other than those administered in this study
  • Baseline corrected Q-T interval (QTc) greater than (>) 470 milliseconds, or baseline symptomatic bradycardia (less than 45 heart beats per minute)
  • Pregnant or breastfeeding women
  • Known Human Immunodeficiency Virus (HIV) positivity or Acquired Immunodeficiency Syndrome (AIDS)-related illness
  • History of hypersensitivity to any of the additives in the alectinib formulation
  • Any clinically significant concomitant disease or condition that could interfere with, or for which treatment might interfere with, the conduct of the study, or absorption of oral medications, or that would, in the opinion of the principal investigator, pose an unacceptable risk to the participant in the study

Trial design

Primary purpose




Interventional model

Single Group Assignment


None (Open label)

138 participants in 1 patient group

Experimental group
Participants will receive alectinib treatment continuously starting from Day 1 Cycle 1 (in 28-day cycles) until disease progression, death, or withdrawal for any other reasons, whichever occurs first. After PD, participants without EGFR mutation will continue treatment with alectinib alone and participants with EGFR mutation will receive alectinib in combination with erlotinib as per discretion of the treating physician.
