Official titleSafety and Incidence of Side Effects in a Cohort of Postmenopausal Women Prescribed Ospemifene Relative to Patients Diagnosed with but not Treated for Vulvar and Vaginal Atrophy (VVA) and Patients on Selective Oestrogen Receptor Modulators (SERMs) for Oestrogen-deficiency Conditions or Breast Cancer Prevention – A Post-Authorisation Safety Study
Study title acronym
Study typeObservational study
Brief description of the studyOestrogen deficiency leads to a decrease in vaginal lubrication, which is an early hallmark of vulvar and vaginal atrophy (VVA). Ospemifene is a non-steroidal selective oestrogen receptor modulator (SERM) approved in the United States for treatment of moderate to severe dyspareunia, a symptom of VVA due to menopause. The SERM class of drugs has been associated with an increased risk of venous thromboembolism (VTE) and cerebrovascular events (CVE). This post-authorisation safety study (PASS) is being undertaken to assess the safety of ospemifene in real life over a period of five years.
The primary objectives are to:
a) Compare the incidence of VTE, among postmenopausal women who are newly prescribed ospemifene (ospemifene cohort) to that among patients diagnosed with but not treated for VVA (untreated VVA comparison cohort).
b) Compare the incidence of VTE, among postmenopausal women who are newly prescribed ospemifene (ospemifene cohort) to that among postmenopausal women newly prescribed other SERM therapies (SERM comparison cohort) being utilised for oestrogen-deficiency conditions (i.e., non-cancer and non-infertility indications) or breast cancer prevention.
This is an observational, retrospective database cohort study using electronic medical records (EMR) and claims databases that will be conducted in 3-EU countries (Italy, Spain and Germany,) and in the United States. All patients with at least one ospemifene prescription or a new diagnosis of VVA with no prescription for VVA (local or systemic oestrogens) or at least one SERM prescription for an oestrogen-deficiency condition or breast cancer prevention are eligible for the study.
The study duration will be up to 5 years, and annual data updates will be obtained from each data source. Annual data updates will continue until the earliest of (1) the target sample size being reached, or (2) 5 years elapsing since first EU launch.

13. Study design
What is the design of the study?
Cohort study
14. Follow-up of patients
Will patients be followed up?Yes
Please describe duration of follow up
The follow-up time for each cohort member will extend from the cohort entry date until their data are no longer available in the database, death, or the end of the study period (estimated to be five years after the cohort entry date).
15. Data analysis plan
Please provide a brief summary of the analysis method
Descriptive statistics will summarise patient demographics, proportion of patients with VTE, proportion of patients prescribed medications related to VTE. Hazard ratios and their 95% confidence intervals will be calculated and appropriate analyses will be conducted for the events of interest. A Cox regression model with time-dependent predictors will be used for the main comparison analysis. The analyses will be carried out separately to compare ospemifene to treatment with SERM and to untreated patients. The analyses would rely on time-dependent indicators to track changes in treatments. The Cox proportional hazard models will be adjusted for confounding factors using fully covariate adjusted models (implemented through inclusion of covariates in the model).
As a secondary analysis, marginal structural models using inverse probability of treatment weighting in time-varying Cox models will be used to compare the risk of each outcome (VTE and stroke) between the treatment cohorts.
