Scientific titleA randomised controlled trial to determine the effect of Decapeptyl® on reduction of prostate volume pre-radiotherapy compared with standard therapy (Zoladex®)
Study acronymEDVART
Study hypothesisThe purpose of the study is to determine the cytoreductive efficacy of Decapeptyl® when used before radical radiotherapy (external beam radiotherapy or brachytherapy) to the prostate. Decapeptyl® will be compared in effect to Zoladex®, in order to show whether it gives as good an effect in reducing prostate size before radiotherapy.
Ethics approval(s)The Oxfordshire Research Ethics Committee (REC) C, 16/09/2010, ref: 10/H0606/43
ConditionProstate cancer patients who are due to undergo radical radiotherapy to the prostate
InterventionTriptorelin (Decapeptyl®) 3 mg or goserelin (Zoladex®) 3.6 mg will be given for three months before radical radiotherapy. All patients will receive a 28 day course of Bicalutamide 50 mg once daily to prevent tumour flare with the first injection of their LHRHa therapy.

Each patients involvement in the study will last for 14 weeks. The study will run for 2 years and we are hoping to start in January, estimated last patient last visit is 31/01/2012.

Due to drug formulations a fully blinded study is not possible; however the doctor performing the rectal ultrasound measurements will be blinded to study treatment.

Pharmaceutical study type(s)
PhaseNot Applicable
Drug / device / biological / vaccine name(s)Triptorelin (Decapeptyl®), goserelin (Zoladex®)

2. Quality of life using questionnaires EQ5D, QLQ-C30 and QLQ-PR25
