Bioequivalence study of two injectable sustained release formulations of Triptorelin (Decatrip® and Dipherelin®) in Patients with prostate cancer
Design
A randomized, two treatment, one period, parallel study
Settings and conduct
This study will be done in Mehr and Imam Khomeini hospitals. 40 Patients with advanced prostate cancer will participate. They will receive a dose of 3.75 mg of triptorelin. Five mL of blood samples will be obtained at 0, 1, 2, 3, 4, 6, 8, 12, 24 hours and 2, 3, 4, 7, 14, 21, 28 day after administration. This is a single blind and parallel study.

Randomization (investigator's opinion)
Randomized
Randomization description
Simple randomization
Administrating of test or reference product for each subject is determined according to the randomization schedule. The randomization schedule is prepared according to entrancing of subject to the study. Each subject is identified by a number from 1 to 40 according to entrancing of subject to the study. Subjects with odd numbers receive the test drug and the subjects with even number receive the reference drug. (test or reference is the same drug but produced with different manufacturers).
Blinding (investigator's opinion)
Single blinded
Blinding description
The study is a single-blind. Patients are blind in this study. Patients are aware of what medication they are taking but do not know whether they are taking the test or reference drug.
The main investigator creates a table using randomization and divides 40 patients in 2 groups which only he knows the details of group. Test or reference drug is prepared base on its brochure, so patients are blinded regarding to the kind of drugs.
Patients are informed that they will be given the Iranian test drug or approved reference drug, although they are unaware of which drug is the test and which is the reference.
Test or reference is the same drug but produced with different manufacturers, so there is not any intervention in treatment.
