Oral Treatment With BIBF 1120 Together With Docetaxel and Prednisone in Patients With Hormone Refractory Prostate Cancer

A Phase I Open Label Dose Escalation Study of Continuous (Except on the Days of Chemotherapy Infusion) Oral Treatment With BIBF 1120 Together With Docetaxel and Prednisone in Patients With Hormone Refractory Prostate Cancer

The primary objective of this study was to determine the safety and Maximum tolerated dose (MTD) of BIBF 1120 combination therapy with docetaxel and prednisone in patients with hormone refractory prostate cancer. Secondary objectives were to characterise the pharmacokinetic profiles of BIBF 1120 and docetaxel and possible Pharmacokinetic (PK) interactions between BIBF 1120 and docetaxel and to obtain preliminary information on anti-tumour activity.

Gastrointestinal abnormalities that would interfere with intake or absorption 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, or melena in the past 3 months and without endoscopic documented resolution), or malabsorption syndromes
8. Previous history of stroke, angor pectoris, ischemic cardiomyopathy, cerebral ischemia, arteritis in the past 6 months
9. Recent history of hemorrhagic or evolutive thrombotic event (including transient ischemic attacks) in the past 6 months
10. Patients who require full-dose anticoagulation or heparinization
11. Absolute neutrophil count (ANC) < 1,500/μl, platelet count < 100,000/μl, or hemoglobin < 8 mg/dL
12. Total bilirubin > upper limit of normal (ULN); alanine amino transferase (ALT) and/or aspartate amino transferase (AST) >1.5 X ULN
13. Serum creatinine > 1.5 mg/dL (> 132 μ mole/L, SI Unit equivalent)
14. Known or suspected active alcohol or drug abuse
15. Patients unable to comply with the protocol

IPD Plan Description

Clinical studies sponsored by Boehringer Ingelheim, phases I to IV, interventional and non-interventional, are in scope for sharing of the raw clinical study data and clinical study documents. Exceptions might apply, e.g. studies in products where Boehringer Ingelheim is not the license holder; studies regarding pharmaceutical formulations and associated analytical methods, and studies pertinent to pharmacokinetics using human biomaterials; studies conducted in a single center or targeting rare diseases (in case of low number of patients and therefore limitations with anonymization).
