Brief Summary:

In India Duphaston is approved and widely used for the treatment of progesterone deficiencies such as for management of dysmenorrhea, endometriosis, secondary amenorrhea, irregular cycles, dysfunctional uterine bleeding, pre-menstrual syndrome, threatened and habitual abortion, infertility due to luteal insufficiency, as well as part of hormone replacement therapy. One Indian study reported normalization of the cycle in 91.6% of women with menstrual problems after three cycles of therapy with dydrogesterone 10 mg given from 11th to the 25th day of the menstrual cycle. The mean cycle duration during dydrogesterone therapy in this study was noted to be 28.8 days, in contrast to 17.9 days (in the polymenorrhea group) and 50.6 days (in the oligomenorrhea group) before therapy. Furthermore, dydrogesterone also decreased the amount and duration of menstrual bleeding in this study.

However, there are limited data regarding Duphaston's role in achieving cycle regularization from post-marketing settings. Moreover, it is not well-known if the effect of Duphaston therapy persists after cessation of treatment and whether the persistent effect, if any, is related to the duration of Duphaston therapy.

Hence, in this observational study, given that (based on previous clinical studies as mentioned above) Duphaston plays a role in menstrual irregularities treatment, the goal is to tease out the possible implications of such treatment in terms of treatment length and response pattern.


Condition or disease
Irregular Menstrual Cycle

Detailed Description:

Primary objective:

• To determine percentage of patients reporting a regular cycle (defined as cycle duration between 21 to 35 days, inclusive) at the end of treatment period.

Secondary objectives:

A. For all patients:

  • To describe evolution of cycle duration from baseline to end of treatment by assessing mean cycle duration (in days) at baseline, separately in polymenorrhea, (i.e., cycle duration < 21 days) and oligomenorrhea (i.e., cycle duration > 35 days) groups, and at the end of treatment.
  • To describe evolution of duration of menstrual bleeding from baseline to end of treatment by assessing mean duration of menstrual bleeding (in days) at baseline and at the end of treatment.
  • To describe evolution of amount of menstrual bleeding from baseline to end of treatment, by assessing average number of pads changed per day at baseline and at the end of treatment.
  • To describe evolution of pain during menstruation (on a 11 point Likert Scale where 0 means no pain and 10 means worst pain) ) from baseline to end of treatment, by assessing mean and standard deviation of pain scores at baseline and at the end of treatment.
  • To describe overall patient satisfaction (on a 5 point Clinical Global Impression of Severity scale, where 1 = very dissatisfied, 2 = dissatisfied, 3 = somewhat satisfied, 4 = satisfied, 5 = very satisfied) at the end of treatment, by assessing percentages of patients in each category at the end of treatment.
  • To describe overall clinical response (on a 7 point Clinical Global Impression of Severity scale, where 1 = Normal, not at all ill, 2 = Borderline mentally ill, 3 = Mildly ill, 4 = Moderately ill, 5 = Markedly ill, 6 = Severely ill, 7 = Most extremely ill) ) at the end of treatment by assessing percentages of patients in each category at the end of treatment.

B. For patients who had achieved regular cycle at the end of treatment:

  • To determine the percentage of patients still experiencing regular cycle (i.e., duration 21-35 days, inclusive) at the end of follow up period, out of total number of patients who had achieved cycle regularization at the end of treatment period.
  • To determine median time to relapse (defined as cycle duration < 21 days or > 35 days) during the follow up period, for patients who had achieved regular cycle at the end of treatment, using Kaplan Meier's method to graphically plot time after cessation of treatment versus percentage of patients still having regular cycles.
  • To determine any correlation between treatment duration (number of cycles of Duphaston treatment received) and persistence of effect (number of months until when regular cycles are maintained after cessation of Duphaston therapy), using linear regression analysis model.
  • To describe evolution of duration of menstrual bleeding from cessation of treatment to end follow up, by assessing mean duration of menstrual bleeding (in days) at end of treatment and at the end of follow up.
  • To describe evolution of amount of menstrual bleeding from cessation of treatment to end follow up, by assessing average number of pads changed per day at end of treatment and at the end of follow up.
  • To describe evolution of pain during menstruation (on a 11 point Likert Scale where 0 means no pain and 10 means worst pain) from cessation of treatment to end follow up, by assessing mean and standard deviation of pain scores at end of treatment and at the end of follow up.

Primary Outcome Measures :
  1. Percentage of Patients Reporting a Regular Cycle [ Time Frame: 6 months ]
    Regular cycle is defined as cycle duration between 21 to 35 days, inclusive at the end of treatment period.


Secondary Outcome Measures :
  1. Change in Cycle Duration (in Days) From Baseline to End of Treatment (EOT) [ Time Frame: 6 months ]
    The evolution of cycle duration from baseline to EOT was assessed by mean cycle duration (in days) at baseline, separately in polymenorrhea and oligomenorrhea groups, and at the EOT. The patients were included in polymenorrhea group in case the cycle duration at baseline was less than 21 days and in oligomenorrhea group in case the cycle duration at baseline was greater than 35 days.

  2. Amount of Menstrual Bleeding From Baseline to End of Treatment [ Time Frame: 6 months ]
    Assessment of average number of pads changed per day at baseline and at the end of treatment (EOT).

  3. Evolution of Pain During Menstruation From Baseline to End of Treatment [ Time Frame: 6 months ]
    The scores for pain during menstruation were recorded on 11-point Likert scale on baseline and end of treatment where 0 means no pain, and 10 means worst pain.

  4. Overall Patient Satisfaction [ Time Frame: 6 months ]
    The overall patient satisfaction was recorded on a 5 point Clinical Global Impression of Severity scale, where 1 = very dissatisfied, 2 = dissatisfied, 3 = somewhat satisfied, 4 = satisfied, 5 = very satisfied).

  5. Evolution of Duration of Menstrual Bleeding From Baseline to End of Treatment [ Time Frame: 6 months ]
    To observe the evolution of duration of menstrual bleeding from baseline to end of treatment by assessing mean duration of menstrual bleeding (in days) at baseline and at the end of treatment.

  6. Overall Clinical Response [ Time Frame: 6 months ]
    Overall response (on a 7 point Clinical Global Impression of Severity scale, where 1 = Normal, not at all ill, 2 = Borderline ill, 3 = Mildly ill, 4 = Moderately ill, 5 = Markedly ill, 6 = Severely ill, 7 = Most extremely ill) at the EOT by assessing percentages of patients in each category at the EOT.
