Clinical trial: Erlotinib Hydrochloride and Quinacrine Dihydrochloride in Stage IIIB-IV Non-Small Cell Lung Cancer

Summary: This phase I trial studies the side effects and best dose of quinacrine dihydrochloride when given together with erlotinib hydrochloride and to see how well it works in treating patients with stage IIIB-IV non-small cell lung cancer. Erlotinib hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as quinacrine dihydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving erlotinib hydrochloride together with quinacrine dihydrochloride may kill more tumor cells

Detailed description: PRIMARY OBJECTIVES:
  I. To assess the safety and tolerability of the combination of erlotinib (erlotinib hydrochloride) and quinacrine (quinacrine dihydrochloride) in patients with advanced non-small-cell lung cancer.
  II. To determine the recommended Maximum Tolerated Dose (MTD) of the combination of erlotinib and quinacrine in patients with advanced non-small-cell lung cancer.
  SECONDARY OBJECTIVES:
  I. To describe the dose limiting toxicity of the erlotinib and quinacrine combination.
  II. To determine the pharmacokinetic profile of the erlotinib and quinacrine combination.
  III. To determine objective response rate (complete response [CR]+partial response [PR]) and clinical benefit rate (CR+PR+ stable disease [SD]) of the erlotinib and quinacrine combination.
  IV. To estimate overall survival (OS)
  OUTLINE: This is a phase I, dose escalation study of quinacrine dihydrochloride
  Escalation Portion: Patients receive erlotinib hydrochloride orally (PO)daily on days 1-28 and quinacrine dihydrochloride PO thrice daily (TID) on days, 1-7 and PO daily from days 8-28.
  After Maximum Tolerated Dose is established: Patients are randomized to 1 of 2 treatment arms.
  ARM I: Patients receive erlotinib hydrochloride PO daily on days 1-28.
  ARM II: Patients receive erlotinib hydrochloride PO and quinacrine dihydrochloride PO daily (TID) on days, 1-7 and PO daily from days 8-28.
  In both arms, courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
  After completion of study treatment, patients are followed up for 30 days.

Eligibility: Inclusion Criteria:
  -  Patients must have histologically or cytologically confirmed incurable malignancy that is surgically unresectable locally advanced, recurrent, or metastatic (stage IIIB/IV) non-small cell lung cancer (NSCLC). Patients with adenocarcinoma, squamous cell carcinoma, large cell carcinoma and sarcomatoid carcinoma will be eligible.
  -  Patients must have received at least one platinum-containing regimen for the treatment of advanced or metastatic disease (except for EGFR-mutant patients). Prior maintenance therapy is allowed and will be considered as the same line of therapy when continued without discontinuation after initiation of a treatment regimen. NSCLC with documented EGFR mutation will be eligible after progression on an EGFR-TKI alone. NSCLC with other molecular targets, such as fusion gene involving the anaplastic lymphoma kinase (ALK) gene (such as echinoderm microtubule associated protein like 4 [EML4]-ALK) or ROS-1 will be eligible if they have progressed on targeted agents (ALK inhibitor) and chemotherapy or are not a candidate for chemotherapy. Adjuvant/neoadjuvant chemotherapy or chemoradiation is considered a line of therapy if < 12 months have elapsed between the last dose and the date of recurrence. Combined treatment with chemotherapy and radiation constitutes a single regimen.

NSCLC patients with EGFR mutation can enroll within 7 days of discontinuing EGFR-TKI.
