Patient case: 48-year-old male with Lung adenocarcinoma. Genetic variant: MET Amplification. Other conditions: Emphysema.

Clinical trial: INC280 and Erlotinib Hydrochloride in Treating Patients With Non-small Cell Lung Cancer

Summary: This phase I trial studies the side effects and best dose of c-Met inhibitor INCB028060 and erlotinib hydrochloride when given together in treating patients with previously treated non-small cell lung cancer. C-Met inhibitor INCB028060 and erlotinib hydrochloride 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 maximum tolerated dose of INC280 (c-Met inhibitor INCB028060) plus erlotinib (erlotinib hydrochloride) in patients with met proto-oncogene (MET) expressing non-small cell lung cancer (NSCLC).
  SECONDARY OBJECTIVES:
  I. To describe the toxicity profile of INC280 plus erlotinib. II. To determine the preliminary efficacy of INC280 plus erlotinib. III. To characterize the pharmacokinetic behavior of this combination.
  TERTIARY OBJECTIVES:
  I. To collect blood and tumor samples for exploratory analysis of the MET and epidermal growth factor receptor (EGFR) signaling pathways.
  OUTLINE: This is a dose-escalation study.
  Patients receive c-Met inhibitor INCB028060 orally (PO) twice daily (BID) and erlotinib hydrochloride PO once daily (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 for 30 days.

  -  Liver disease (i.e. cirrhosis, chronic active hepatitis, chronic persistent hepatitis)
  -  Symptomatic central nervous system (CNS) metastases that are neurologically unstable or requiring increasing doses of steroids to control CNS disease
  -  Note: Patients with controlled CNS metastases are allowed; radiotherapy or surgery for CNS metastases must have been completed > 2 weeks prior to study entry; patients must be neurologically stable, having no new neurologic deficits on clinical examination, and no new findings on CNS imaging; steroid use for management of CNS metastases must be at a stable dose for two weeks preceding study entry
  -  Receiving drugs known to be strong inducers of cytochrome P450 3A4 (CYP3A4) or inhibiting drugs known to interact with erlotinib including, but not limited to: enzyme-inducing anticonvulsants, rifampicin, rifabutin, St John wort and ketoconazole
  -  Treatment with proton pump inhibitors within 3 days prior to study entry
  -  Currently receiving any prohibited medications including vitamins and herbal supplements
  -  Any other condition that would, in the investigator's judgment, contraindicate participation in the clinical study due to safety concerns or compliance with clinical study procedures, e.g., infection/inflammation, intestinal obstruction, unable to swallow medication, social/ psychological issues, etc.
  -  Pregnant or nursing (lactating) women, where pregnancy is defined as the state of a female after conception and until the termination of gestation, confirmed by a positive human chorionic gonadotropin (hCG) laboratory test (> 5 mIU/mL)
