Benefits of technology

The patent describes a method of treating dysmenorrhea by using a natural substance called biogenic estrogrens. This substance is found in the body and has a good tolerability and safety profile when used at normal levels. The method reduces the side effects associated with other treatments, such as headaches, breast pain, and blood clots. Overall, the method has a better profile than other treatments for dysmenorrhea.

Problems solved by technology

The pain is usually crampy and intermittently intense, but may be a continuous dull ache.
Although the pain is usually strongest in the midline, some women also have severe back and / or thigh pain.
In such a case, there is a (dose dependent) risk of undesirable side-effects, such as thromboembolism, fluid retention, nausea, bloating, cholelithiasis, headache and breast pain.

example 1

[0089]During that study, healthy female subjects were treated for one 28-day cycle with either 10 or 20 mg E4 alone (n=10 and 11, respectively) or with a combination of E4 with either Progesterone (P) or Desogestrel (DSG) (n=15 or 16, respectively).

[0090]At baseline, occasional dysmenorrhea was reported by 11 subjects (21.2%), and frequent dysmenorrhea was reported by 19 subjects (36.5%). The distribution of dysmenorrhea is shown in Table 2 below. Overall, dysmenorrhea was reported by 25% to 53.3% of the subjects included in this trial.

example 2

[0092]In this clinical study comparing different doses and different combinations of estrogenic components and progestogenic components according to the invention, overall, at baseline, 68.9% of subjects had previously experienced dysmenorrhea, which was occasional in 40.4% of subjects and frequent in 28.5% of subjects.

[0093]As illustrated in Table 4 below extracted from Treatment-emergent adverse events (TE-AE) reported by at least 2 subjects in any treatment group, dysmenorrhea was more rarely reported when the progestogenic component was drospirenone than when it was levonorgestrel.

[0094]Additionally, and quite surprisingly, it is also seen in Table 4 that the lowest dose of the estrogenic component (15 mg daily) leads to fewer reports of dysmenorrhea as TE-AE than the higher dose (20 mg daily).

example 3

[0096]In this clinical study comparing the combination of estrogenic component and progestogenic component according to the invention with a commercially available contraceptive treatment using also a natural estrogen (estradiol valerate at a 1, 2 or 3 mg dose of with dienogest at a dose of 0, 2 or 3 mg, marketed as Qlaira ® by Bayer HealthCare, Germany), the number of drug-related adverse events (Treatment-emergent adverse events (TE-AE) reported by at least 2 subjects in any treatment group) and the levels of the SHBG marker were monitored.

[0097]As illustrated in Table 5 below, 13 subjects (corresponding to 16.7%) reported TE-AEs related to headache in the treatment arm with the commercial product based on estradiol valerate and dienogest, while only 6 subjects (corresponding to 7.6%) did so in the group treated with a combination of 15 mg of estetrol and 3 mg of drospirenone. The number of events related to headache was thus shown to be much lower for the treatment according to t...

Abstract

The present invention relates to a method for the management of dysmenorrhea involving administration of an estrogenic component which is preferably selected from the group consisting of estetrol and estetrol-like compounds. Estetrol-like compounds have been surprisingly found to be capable of mitigating dysmenorrhea, either when used alone or in combination with progestogenic components, and this to an extent surpassing the effect obtained with other compositions and with a favourable side-effect profile compared to currently available methods.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a method of alleviating the symptoms of dysmenorrhea in a person, comprising administering to said person an effective amount of an estrogenic component. More particularly the estrogenic component is an estetrol component, as further defined herein, and the method enjoys a favourable side-effect profile compared to currently available methods.BACKGROUND ART[0002]Dysmenorrhea is a medical condition characterized by the presence of recurrent, crampy, lower abdominal pain that occurs during menses. Most women begin having dysmenorrhea during adolescence, usually within four to five years of the first menstrual period. Painful periods become less common as women age. For clinical purposes, dysmenorrhea is divided into two broad categories, primary and secondary dysmenorrhea. Primary dysmenorrhea refers to the presence of recurrent, crampy, lower abdominal pain that occurs during menses in the absence of demonstrable disease th...
