6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
The safety of OSPHENA has been assessed in ten phase 2/3 trials (N=2209) with doses ranging from 5 to 90 mg per day.
The duration of treatment in these studies ranged from 6 weeks to 15 months.
The majority of women (N=1683) had treatment exposure up to 12 weeks;
847 had up to 52 weeks (1 year) of exposure.
The incidence rates of thromboembolic and hemorrhagic stroke were 1.13 per thousand women years (1 reported case of thromboembolic stroke) and 3.39 per thousand women years (3 reported cases of hemorrhagic stroke), respectively in OSPHENA 60 mg treatment group and 3.15 (1 case of thromboembolic stroke) and 0 per thousand women years, respectively in placebo.
There were 2 reported cases of DVT among the 1459 women in the OSPHENA 60 mg treatment group and 1 case of DVT among the 1136 women in the placebo group.
5 WARNINGS AND PRECAUTIONS Venous Thromboembolism: Risk of DVT and PE ( 5.1 ) Known, suspected, or history of breast cancer ( 5.2 ) Severe Hepatic Impairment ( 5.3 , 8.7 , 12.3 ) 5.1 Cardiovascular Disorders Manage appropriately any risk factors for cardiovascular disorders, arterial vascular disease (for example, hypertension, diabetes mellitus, tobacco use, hypercholesterolemia, and obesity) and/or venous thromboembolism (VTE) (for example, personal history or family history of VTE, obesity, and systemic lupus erythematosus).
Stroke In the clinical trials for OSPHENA (duration of treatment up to 15 months), the incidence rates of thromboembolic and hemorrhagic stroke were 1.13 and 3.39 per thousand women years, respectively in OSPHENA 60 mg treatment group and 3.15 and 0 per thousand women years in placebo.
Immediately discontinue OSPHENA if a thromboembolic or hemorrhagic stroke occurs or is suspected.
The WHI estrogen-alone substudy reported a statistically significant increased risk of stroke in women 50 to 79 years of age receiving daily CE (0.625 mg)-alone compared to women in the same age group receiving placebo (45 versus 33 strokes per ten thousand women years, respectively).
The increase in risk was demonstrated in year 1 and persisted.
Like all medications, Osphena can cause side effects. However, not everyone who takes this medication will experience them. Many side effects are dose-dependent and may improve as your body adjusts to the medication. Others may require dose adjustment or medical attention.
