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 data described below reflect pooled data from 5 clinical trials of estradiol transdermal system continuous delivery (once-weekly).

A total of 614 women were exposed to estradiol transdermal system continuous delivery (once-weekly) for 3 months (193 women at 0.025 mg per day, 201 women at 0.05 mg per day, 194 women at 0.1 mg per day) in randomized, double-blind trials of clinical efficacy versus placebo and versus active comparator.

All women were postmenopausal, had a serum estradiol level of less than 20 pg/mL, and a minimum of five moderate to severe hot flushes per week or a minimum of 15 hot flushes per week of any severity at baseline.

Included in this table are an additional 25 postmenopausal hysterectomized women exposed to estradiol transdermal system continuous delivery (once-weekly) 0.025 mg per day for 6 to 24 months (N = 16 at 24 months) in a randomized, double-blind, placebo-controlled study of estradiol transdermal system continuous delivery (once-weekly) for the prevention of osteoporosis.

Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
