Brief summary

The purpose of this study is to assess rates of administration of add-back therapy in patients with endometriosis in the Russian Federation, during a 6-month course of gonadoliberin agonist leuprorelin 3.75 mg.

Detailed description

This was a non-interventional, observational program in which Lucrin Depot (leuprorelin acetate) and add-back therapy (hormone and non-hormone) were prescribed in the usual manner in accordance with the terms of the local marketing authorization with regards to dose, population and indication (for leuprorelin acetate) and with regards to the local guidelines or therapeutic recommendation (for add-back therapy). The rationale for the study was the necessity to characterize the patient population and long-term leuprorelin acetate administration in the Russian Federation. Further, it was important to characterize the compliance, tolerability, and safety profile of this therapy in the routine clinical care setting in the Russian Federation.

Participants by arm

ArmCount
Leuprorelin
Patients with genital endometriosis received leuprorelin (Lucrin Depot®) in accordance with the respective marketing authorization/manufacturer's directions. All participants received leuprorelin for up to 6 months intramuscularly at a dose of 3.75 mg once a month. If intramuscular administration was not possible, leuprorelin was injected subcutaneously at a dose of 3.75 mg once a month. The first injection was to be carried out on the 3rd day of a menstrual period. Accepted options for add-back therapy included: monophasic combined low-dose products for hormonal replacement therapy; combined oral contraceptives; and, if use of hormones was not possible, phytoestrogens with calcium products.
