Dose Escalation of BIBF 1120 Combined With Pemetrexed in Advanced Non Small Cell Lung Cancer

A Phase I Open Label Study of Continuous Oral Treatment With BIBF 1120 Together With Pemetrexed in Previously Treated Patients With Non-small Cell Lung Cancer

The primary objective was to determine the safety, tolerability and maximum tolerate dose (MTD) of BIBF 1120 in combination with pemetrexed. Secondary objectives were to characterize the pharmacokinetic profiles of BIBF 1120 and pemetrexed and to obtain preliminary anti-tumour efficacy information.

Inclusion Criteria:

• Pathologic confirmation of metastatic, unresectable, or locally advanced NSCLC (non-small cell lung cancer)
• Disease progression during or following one prior platinum-based (including prior neoadjuvant or adjuvant therapy) chemotherapy regimen for advanced disease
• Bi-dimensionally measurable disease by one or more techniques (CT (computed tomography), MRI (magnetic resonance imaging), X-ray)
• Age 18 years or older
• Life expectancy of at least three (3) months
• Eastern Cooperative Oncology Group (ECOG) performance score 0-2
• Written informed consent that is consistent with ICH-GCP (International Conference on Harmonization - Good Clinical Practice) guidelines

Exclusion Criteria:

• Participation in another clinical study within the past 28 days prior to the start of therapy or concomitantly with this study
• Treatment for NSCLC (except radiotherapy for palliative reasons) within the past 28 days prior to Treatment Day 1 of this trial. All toxicities of the previous therapy must have resolved to baseline prior to Treatment Day 1
• Patient has received more than one prior chemotherapy regimen for advanced disease
• Radiotherapy to an area of measurable disease (unless disease progression had been documented following completion of therapy)
• Patients who are unwilling or unable to take folic acid and vitamin B12 supplementation
• Radiotherapy within 4 weeks prior to Treatment Day 1
• Prior treatment with agents that target the vascular endothelial growth factor (VEGF) pathways, including monoclonal antibody therapy (such as bevacizumab) or tyrosine kinase inhibitors
• Active brain metastases (stable for <28 days, symptomatic, or requiring concurrent steroids or antiepileptic therapy). Patients who have received prior whole brain irradiation and whose brain metastases are stable according to the criteria above will not be excluded
• Centrally located tumors with radiologic evidence (CT or MRI) of local invasion of major blood vessels, with exception of those tumors which have received prior irradiation and are stable
• Cavitary or necrotic tumors
• Sanguinous pleural effusion due to disease or pericardial effusion suspicious for disease
• Other active malignancy diagnosed within the past 3 years (other than non-melanomatous skin cancer)
• Gastrointestinal abnormalities that would interfere with intake or absorption (with exception of patients with gastric esophageal reflux disease controlled with proton pump inhibitors) of the study drug, such as a requirement for intravenous alimentation, prior surgical procedures affecting absorption, treatment for peptic ulcer disease within the last 6 months, active gastrointestinal bleeding unrelated to cancer (as evidenced by either hematemesis, hematochezia, or melena in the past 3 months and without endoscopic documented resolution), or malabsorption syndromes
• Significant cardiovascular disease (i.e., uncontrolled hypertension, myocardial infarction within 6 months, unstable angina, serious cardiac arrhythmia, >2 New York Heart Association (NYHA) Grade 2 congestive heart failure)
• History of hemorrhagic or thrombotic event (including transient ischemic attacks) in the past 12 months or clinically significant hemoptysis in the past 3 months
• Patients receiving any anti-coagulant therapy (including coumadin, heparin, low molecular weight heparin, and aspirin
• Patient has received prior therapy with pemetrexed
• Absolute neutrophil count (ANC) ≤1,500/μl, platelet count ≤100,000/μl, or hemoglobin <9 gm/dL
• Total bilirubin >1.5 mg/dL (26 μmole/L, SI-Unit equivalent), alanine amino transferase (ALT) and/or aspartate amino transferase (AST) ≥1.5 X upper limit of normal (ULN)
• Inadequate renal function determined by a serum creatinine level >1.5 X ULN
• Patient is unable or unwilling to interrupt aspirin or other NSAIDS for a 5-day period (8 days period for long lasting agents like piroxicam)
• Persistent hematuria or proteinuria (more than trace)
• Women and men who are sexually active and unwilling to use a medically acceptable method of contraception
• Pregnancy or breast feeding
• Known or suspected active alcohol or drug abuse
• Patients unable to comply with the protocol
