E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Postmenopausal estrogen replacement regimen is the therapy of choice for the alleviation of climacteric symptoms. During the past few years, continuous-combined hormone replacement therapy (HRT) have become increasingly popular. Lower dose estrogen-progestogen combinations are likely to induce less bleeding disturbances and other adverse effects (AEs) and may therefore improve compliance and allow long-term treatment, necessary, e.g. for the prevention of postmenopausal bone loss.

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of the study is to investigate efficacy and safety of 3 continuous combined regimens of Indivina in alleviation of vasomotor (estrogen deficiency) symptoms in women who are more than 1 year menopausal, by measuring the change in frequency and severity of moderate to severe vasomotor symptoms from baseline to Week 12 vasomotor (estrogen deficiency) symptoms using a self-assessed symptoms diary. |
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives include investigations of bleeding days, vasomotor symptoms, alleviation of other estrogen deficiency symptoms, and quality of life (QoL). |

Definition of the end of the trial and justification where it is not the last
visit of the last subject undergoing the trial
|
Study subjects are free to withdraw from the study at any time without providing a reason, a study subject needs to discontinue the study, if the investigator considers the discontinuation to be medically necessary. Meeting any of the exclusion criteria during the study is also a criterion for discontinuation , Hyperplasia in histological evaluation of endometrial biopsy at Week 24 will be considered as a treatment failure and will lead to discontinuation in the study.
