Patient case: 65-year-old female with squamous cell lung cancer; genetic feature: FGFR1 amplification

Clinical trial: Phase 1 Erlotinib and Dovitinib (TKI258) in Advanced Non-small Cell Lung Cancer (NSCLC)

Summary: This phase I trial studies the side effects and best dose of giving erlotinib and dovitinib together to treat patients with metastatic non-small cell lung cancer. Erlotinib blocks the epidermal growth factor receptor (EGFR) and has known activity in non-small cell lung cancer and dovitinib blocks the fibroblast growth factor receptor (FGFR) and other targets which may be important to treat lung cancer. The combination of both drugs may work better than either drug alone, but may also have increased side effects. This trial will look at the side effects of combining the drugs and look for how effective the combination may be.

Detailed description: PRIMARY OBJECTIVES:
  I. To characterize the safety and tolerability of the combination of erlotinib (erlotinib hydrochloride) and dovitinib (dovitinib lactate), assessing for toxicity using the Common Terminology Criteria for Adverse Events (CTCAE) version 4.0.
  II. To determine the maximum tolerated dose (MTD) of the combination of erlotinib and dovitinib.
  SECONDARY OBJECTIVES:
  I. To evaluate overall response rate (ORR), progression free survival (PFS), and overall survival (OS) of patients receiving the combination of erlotinib and dovitinib, although this phase will allow for patients who received any number of prior treatments, including prior treatment with erlotinib.
  II. To evaluate the potential impact of dovitinib on erlotinib pharmacokinetics (PK).
  OUTLINE: This is a dose-escalation study.
  Patients receive erlotinib hydrochloride orally (PO) once daily (QD). Starting on day 15, patients also receive dovitinib lactate PO QD on days 1-5 of each week. Treatment continues in the absence of disease progression or unacceptable toxicity.
  After completion of study treatment, patients are followed up for 12 months.

  -  Patients who have undergone major surgery =< 4 weeks prior to starting study drug or who have not recovered from side effects of such therapy
  -  If history of other primary cancer, subject will be eligible only if she or he has:
  -  Curatively resected non-melanomatous skin cancer, basal cell carcinoma, squamous cell carcinoma
  -  Curatively treated cervical carcinoma in situ
  -  Other primary solid tumor curatively treated with no known active disease present and no treatment administered for the last 3 years
  -  Subjects known to have chronic or active hepatitis B or C infection with impaired hepatic function (ineligible if AST and ALT > 2.5 x ULN)
  -  History of any medical or psychiatric condition or laboratory abnormality that in the opinion of the investigator may increase the risks associated with study participation or study drug administration or may interfere with the conduct of the study or interpretation of study results
  -  Patients who continue to smoke (given that smoking decreases serum levels of erlotinib)
  -  Female subject who is breast-feeding or who has positive serum pregnancy test 72 hours prior to enrollment
  -  Any of the following concurrent severe and/or uncontrolled medical conditions within 6 months of enrollment which could compromise participation in the study:
