Multicenter Study Clinical TrialEfficacy of leuprorelin acetate depot in symptomatic fibromatous uteri: the Italian Multicentre Trial.
A total of 110 nonmenopausal women (mean age 42.1 years) presenting with symptomatic uterine leiomyomata and/or fibromatous uteri have been enrolled in this trial to evaluate the efficacy of the depot formulation of leuprorelin acetate in decreasing uterine volume and minimizing menorrhagia, dysmenorrhoea and pressure over the bladder. All patients were treated with an intramuscular injection of leuprorelin acetate depot 3.75 mg every 4 weeks for 16 weeks. Clinical examinations and hormonal and ultrasound determinations were performed before, during and at the end of treatment. ⋯ In most patients the achievement of amenorrhoea minimized the fear of surgical emergency, facilitating an increased awareness of their clinical condition. With the exception of the three patients who dropped out, side effects were mild in all patients, consisting mainly of hot flushes, which were easily tolerated. In the following 8-12 months, the regrowth of uterine volume to original size has been usual in most of the 82 patients now in follow-up.(ABSTRACT TRUNCATED AT 400 WORDS)

Comparative Study Clinical Trial Controlled Clinical TrialClinical and endocrine effects of leuprorelin acetate in pre- and postmenopausal patients with advanced breast cancer.
Premenopausal Study. Twenty-five pre- or perimenopausal patients with advanced breast cancer were treated with leuprorelin acetate 3.75 mg (n = 9) or 7.5 mg (n = 16) every 4 weeks. Serum levels of gonadotrophins and oestrogens were suppressed markedly by both doses and there was no indication that the lower dose was less effective as an oestrogen suppressant. ⋯ Endocrine effects after 4 weeks' treatment included major suppression of serum gonadotrophins to below 10% of pretreatment values and decreases in the level of serum testosterone in 12 of 14 patients. In this group there were no changes in oestradiol levels, although we had previously observed suppression in postmenopausal patients treated with goserelin. In common with other gonadotrophin-releasing hormone analogues, leuprorelin acetate cannot be recommended as a treatment for postmenopausal breast cancer.

Multicenter Study Clinical TrialTreatment of endometriosis with leuprorelin acetate depot: a German multicentre study.
During the past decade, the development of various gonadotrophin-releasing hormone (Gn-RH) agonists, which induce reversible hypo-oestrogenism has opened a new area in the medical management of endometriosis. In an open, multicentre phase III study, the efficacy, tolerance and safety of the Gn-RH agonist leuprorelin acetate were tested. The preliminary results of 104 women treated in seven German centres are presented. ⋯ During the 6 months' treatment, laboratory parameters showed no significant deviations from normal; only total cholesterol, high-density lipoprotein cholesterol and alkaline phosphatase increased. Treatment results were judged as good and satisfactory in 82% and 11% of cases, respectively. On the basis of this study, it can be concluded that leuprorelin acetate treatment is safe, well tolerated and effective in the medical management of endometriosis and endometriosis-related complaints.

Multicenter Study Clinical TrialExperience with leuprorelin acetate depot in the treatment of fibroids: a German multicentre study.
Between October 1988 and October 1990 in a noncomparative multicentre study, 114 patients were treated for uterine fibroids with the gonadotrophin-releasing hormone (Gn-RH) agonist, leuprorelin acetate depot. The mean age of the women was 33 years and 55.3% of them had a history of infertility. After confirmation of the diagnosis by ultrasound and/or operation, treatment began between day 1 and 3 of the cycle with leuprorelin acetate depot 3.75 mg subcutaneously. ⋯ Liver and lipid metabolism was almost unaffected, although increasing calcium and alkaline phosphatase serum levels as well as an increased urinary calcium/creatinine ratio demonstrated an increased metabolic turnover of the bone. Haemoglobin concentrations, however, increased in those cases with fibroid-related anaemia. Thus the slow-release form of leuprorelin acetate is an adjunct to myomectomy especially in those women in whom family planning is not yet completed.
