Evaluation of a continuous regimen of levonorgestrel/ethinyl estradiol: phase 3 study results.

OBJECTIVE: This study was conducted to evaluate the safety and efficacy of a continuous daily regimen of levonorgestrel (LNG) 90 microg/ethinyl estradiol (EE) 20 microg (continuous LNG/EE). METHODS: Healthy women aged 18-49 years with regular menstrual cycles for 3 months enrolled in this single-treatment open-label study and took one pill of LNG 90 microg/EE 20 microg daily for 12 months. RESULTS: For the 2134 subjects enrolled, the Pearl Index method failure was 1.26, and user failure was 0.34. While on Pill Pack 13, 58.7% of subjects reported amenorrhea and 79.0% reported absence of bleeding. Overall, the number of bleeding and spotting days per pill pack declined progressively. Adverse events and discontinuations were comparable to those reported for cyclic oral contraceptive (OC) regimens, except for higher rates in those related to uterine bleeding. CONCLUSIONS: Continuous LNG/EE demonstrated a good safety profile and efficacy similar to cyclic OCs. The regimen continuously inhibited menses, increased the incidence of amenorrhea over time and, except for a subset of women, decreased the number of bleeding and spotting days.

Effectiveness of simvastatin therapy in raising HDL-C in patients with type 2 diabetes and low HDL-C.

OBJECTIVE: To evaluate the efficacy of high and moderate doses of simvastatin (80 and 40 mg), for raising high density lipoprotein-cholesterol (HDL-C), improving HDL sub-fractions, and affecting other parameters, including high sensitivity C-reactive protein (hs-CRP), in patients with type 2 diabetes mellitus (DM) and low HDL-C. RESEARCH DESIGN AND METHODS: This double-blind, placebo-controlled, randomized, 3-period, complete block, 6-week crossover study examined the efficacy of simvastatin in adult men and women (N = 151) with stable type 2 DM (HbA(1C) < 9%), low density lipoprotein-cholesterol (LDL-C) > 100 mg/dL (2.6 mmol/L), HDL-C < 40 mg/dL (< 1 mmol/L), and fasting triglyceride level > 150 (> 1.7 mmol/L) and < 700 mg/dL (< 7.9 mmol/L). This study included adult men (71%) and women (29%) of various races (89% white, 6% black, 1% Asian, 3% other) enrolled from 29 practice-based sites in the United States. MAIN OUTCOME MEASURES: Percentage change in HDL-C from baseline at the end of each 6-week treatment interval. RESULTS: Both simvastatin 80 and 40 mg significantly increased total HDL-C from baseline (mean increases of 8% +/- 1 [SE] and 5% +/- 1, respectively; p < 0.001) compared with placebo, and significantly reduced plasma concentrations of LDL-C (p < 0.001), triglycerides (p < 0.001), apolipoprotein B (p < 0.001), and hs-CRP (p < or = 0.012). Compared with simvastatin 40 mg, the 80 mg dose provided additional efficacy. Simvastatin 80 mg also significantly (p < 0.001) increased HDL(2) from baseline (14% +/- 3[SE]) and placebo phases (10 +/- 3). An exploratory analysis showed 87% (simvastatin 80 mg) and 82% (simvastatin 40 mg) of patients reached the NCEP ATP III treatment goals for LDL-C compared with 14% on placebo. CONCLUSIONS: Both simvastatin 80 and 40 mg raise HDL-C and improve other measures associated with elevated coronary risk in patients with type 2 DM and low HDL-C.
