Study information

Primary study design	Interventional
Study design	Prospective open multi-centr, randomised controlled phase IIb trial
Secondary study design	Randomised controlled trial
Scientific title	A Prospective, Randomised trial Of Simultaneous Pancreatic cancer treatment with Enoxaparin and ChemoTherapy
Study acronym	PROSPECT
Study objectives	To reduce thromboembolic events from 10% to 3% within three months with treatment with Enoxaparin.
Ethics approval(s)	Ethical approval granted from the local ethical committee (Charite - Universitaetsmedizin Berlin Ethik-Kommission) on the 29th March 2004 (ref: 69/2004).
Health condition(s) or problem(s) studied	Pancreatic cancer
Intervention	After stratification according to Karnofsky Performance Status (KPS), kidney function, tumour stage, recurrent disease, primary disease, DVT in the past patients will be randomised to treatment with/without enoxaparin. Patients with KPS greater than 80% and normal kidney function receive gemcitabine 1 g/m^2 (30 minutes), cisplatin 30 mg/m^2 (90 minutes), 5-fluorouracil 750 mg/m^2 (24-hours) and folinic acid 200 mg/m^2 (30 minutes) (GFFC), with/without low molecular weight heparin (LMWH) on days 1 and 8 every three weeks with/without enoxaparin 1 mg/kg daily subcutaneously (sc). Patients with KPS less than 80% and increased creatinine plasma levels (greater than 1.3 mg/dl) receive the current standard therapy (gemcitabine 1 g/m^2 (30 minutes) on days 1, 8 and 15 every four weeks) with/without enoxaparin 1 mg/kg daily sc. After 12 weeks of initial chemotherapy all patients who have not progressed received the standard therapy (gemcitabine 1 g/m^2 (30 minutes) on days 1, 8 and 15 every four weeks) with/without enoxaparin 40 mg daily sc.
Intervention type	Drug
Phase	Phase II/III
Drug / device / biological / vaccine name(s)	Enoxaparin
Primary outcome measure(s)	To reduce thromboembolic events from 10% to 3% within three months (Kaplan Meyer estimation).
Key secondary outcome measure(s)	1. Reduction of thromboembolic rate at timepoints 6, 9 and 12 months (Kaplan Meyer estimation) 2. Time to progression 3. Overall survival, progression free survival: Kaplan Meyer Plot (current version of SPSS) 4. Rate of remission: description with tabulations, as percentage of the two treatment groups, duration of remission 5. Toxicity: National Cancer Institute (NCI) Common Toxicity Criteria (CTC) grade differentation, description with tabulations 6. Quality of life: tabulation descriptions, assesment with box-plot (current version of SPSS)
Completion date	01/04/2009
