New Data Presented Demonstrates Ovulatory Effect of Teva Women's Health's Investigational 28-Day Oral Contraceptive
- Results from Phase I Clinical Trial Presented at the 61 st Annual Clinical Meeting of the American Congress of Obstetricians and Gynecologists -
NORTH WALES, Pa.--(BUSINESS WIRE)-- Teva Women's Health, a U.S.-based subsidiary of Teva Pharmaceutical Industries Ltd., presented new data on ovulation inhibition and ovarian activity from a Phase I clinical trial of Teva's investigational 28-day oral contraceptive (OC) (150 mcg desogestrel (DSG)/20 mcg ethinyl estradiol (EE) for 21 days, followed by 7 days of 10 mcg EE), an investigational monthly regimen. The results were presented at the 61st Annual Clinical Meeting of the American Congress of Obstetricians and Gynecologists (ACOG).
Data were presented from a randomized, open-label comparative study of 142 women, aged 18 to 35 years, which compared ovulation inhibition and ovarian activity of Teva's investigational 28-day OC to two contraceptive regimens containing different synthetic progestins. The primary endpoints were ovarian follicular development, and progesterone and estradiol levels. Women in the study were randomized to one of the following groups for three consecutive 28-day cycles:
- Treatment 1: Teva's investigational 28-day OC, 150 mcg DSG/20 mcg EE for 21 days, followed by seven days of 10 mcg EE
- Treatment 2: 3 mg drospirenone and 20 mcg EE for 24 days, followed by four days of placebo pills
- Treatment 3: 1 mg levonorgestrel and 20 mcg EE for 21 days, followed by seven days of placebo pills
Results showed that, following the three-month treatment period, ovarian activity was reduced in subjects receiving treatments with modified hormone-free intervals. Although all three treatment groups showed reduced ovarian activity, Teva's investigational 28-day OC reduced ovarian activity more than Treatment 3, the levonorgestrel regimen, and had effects similar to Treatment 2, the drospirenone regimen. In addition, Teva's investigational 28-day OC presented a safety profile that was similar to that of the two commercial comparators in the study as well as other commercially available 28-day OCs on the market. The most common treatment-emergent adverse events were upper respiratory tract infection (19%) and headache (17%).
"These data support the potential of Teva's new investigational 28-day oral contraceptive to prevent pregnancy by inhibiting ovulation," said Larry Seidman, D.O., principal investigator at Clinical Research of Philadelphia. "Although many contraceptive options are available, studying new regimens provides additional choices for women deciding on the appropriate contraception for them."
Traditional "21/7" oral contraceptive regimens include 21 days of "active pills" and a hormone-free interval (HFI) during which a woman takes placebo pills. Teva's investigational DSG OC regimen eliminates the HFI by adding seven days of 10 mcg EE during the traditional HFI.
"We are encouraged by the data presented on Teva's investigational 28-day oral contraceptive at ACOG this year, which demonstrated that the regimen achieves an ovulatory effect," said Nancy Ricciotti, senior director of clinical affairs, Teva Women's Health R&D. "These data are a testament to our dedication to provide women with innovative contraceptive and family planning products."
About Teva's Investigational 28-Day Oral Contraceptive
Teva's investigational 28-day oral contraceptive (150 mcg desogestrel/20 mcg ethinyl estradiol for 21 days, followed by seven days of 10 mcg ethinyl estradiol) is a desogestrel regimen that is being evaluated as a 28-day oral contraceptive. Teva's investigational 28-day oral contraceptive eliminates the traditional hormone-free interval (HFI), which means that there are no placebos (sugar pills) in the regimen. Instead, the regimen adds seven days of 10 mcg ethinyl estradiol during the traditional HFI.
