Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.Plan One-Step was studied in randomized, double-blinded multicenter clinical trial. In this study, all women who had received at least one dose of study medication were included in the safety analysis: 1,379 women in the Plan One-Step group, and 1,377 women in the Plan group (2 doses of 0.75 mg levonorgestrel taken 12 hours apart). The mean age of women given Plan One-Step was 27 years. The racial demographic of those enrolled was 54% Chinese, 12% Other Asian or Black, and 34% were Caucasian in each treatment group. 1.6% of women in the Plan One-Step group and 1.4% in Plan group were lost to follow-up. The most common adverse events (>10%) in the clinical trial for women receiving Plan One-Step included heavier menstrual bleeding (30.9%), nausea (13.7%), lower abdominal pain (13.3%), fatigue (13.3%), and headache (10.3%).

CARCINOGENESIS & MUTAGENESIS & IMPAIRMENT OF FERTILITY SECTION.


13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility. Carcinogenicity: There is no evidence of increased risk of cancer with short-term use of progestins. There was no increase in tumorgenicity following administration of levonorgestrel to rats for years at approximately ug/day, to dogs for years at up to 0.125 mg/kg/day, or to rhesus monkeys for 10 years at up to 250 ug/kg/day. In another year dog study, administration of levonorgestrel at 0.5 mg/kg/day did increase the number of mammary adenomas in treated dogs compared to controls. There were no malignancies.Genotoxicity: Levonorgestrel was not found to be mutagenic or genotoxic in the Ames Assay, in vitro mammalian culture assays utilizing mouse lymphoma cells and Chinese hamster ovary cells, and in an in vivo micronucleus assay in mice. Fertility: There are no irreversible effects on fertility following cessation of exposures to levonorgestrel or progestins in general.

CLINICAL PHARMACOLOGY SECTION.


12 CLINICAL PHARMACOLOGY. 12.1 Mechanism of Action. Emergency contraceptive pills are not effective if woman is already pregnant. Plan One-Step is believed to act as an emergency contraceptive principally by preventing ovulation or fertilization (by altering tubal transport of sperm and/or ova). In addition, it may inhibit implantation (by altering the endometrium). It is not effective once the process of implantation has begun.. 12.3 Pharmacokinetics. AbsorptionFollowing single dose administration of Plan One-Step in 30 women under fasting conditions, maximum plasma concentrations of levonorgestrel of 19.1 ng/mL were reached at 1.7 hours. See Table 2.Table 2. Pharmacokinetic Parameter Values Following Single Dose Administration of Plan One-Step (levonorgestrel) tablet 1.5 mg to 30 Healthy Female Volunteers under Fasting ConditionsMean (+- SD)Cmax (ng/mL)AUCt (ng.hr/mL)N=29 AUCinf (ng.hr/mL) Tmax (hr)median (range) t1/2 (hr)Levonorgestrel19.1 9.7)294.8 208.8)307.5( 218.5)1.7 (1.0-4.0)27.5 5.6)Cmax maximum concentrationAUCt area under the drug concentration curve from time to time of last determinable concentrationAUCinf area under the drug concentration curve from time to infinityTmax time to maximum concentrationt1/2 elimination half lifeEffect of Food: The effect of food on the rate and the extent of levonorgestrel absorption following single oral administration of Plan One-Step has not been evaluated. DistributionThe apparent volume of distribution of levonorgestrel is reported to be approximately 1.8 L/kg. It is about 97.5 to 99% protein-bound, principally to sex hormone binding globulin (SHBG) and, to lesser extent, serum albumin.MetabolismFollowing absorption, levonorgestrel is conjugated at the 17-OH position to form sulfate conjugates and, to lesser extent, glucuronide conjugates in plasma. Significant amounts of conjugated and unconjugated 3, 5-tetrahydrolevonorgestrel are also present in plasma, along with much smaller amounts of 3, 5-tetrahydrolevonorgestrel and 16hydroxylevonorgestrel. Levonorgestrel and its phase metabolites are excreted primarily as glucuronide conjugates. Metabolic clearance rates may differ among individuals by several-fold, and this may account in part for the wide variation observed in levonorgestrel concentrations among users. ExcretionAbout 45% of levonorgestrel and its metabolites are excreted in the urine and about 32% are excreted in feces, mostly as glucuronide conjugates. Specific Populations PediatricThis product is not intended for use in the premenarcheal population, and pharmacokinetic data are not available for this population.GeriatricThis product is not intended for use in postmenopausal women, and pharmacokinetic data are not available for this population.RaceNo formal studies have evaluated the effect of race. However, clinical trials demonstrated higher pregnancy rate in Chinese women with both Plan and the Yuzpe regimen (another form of emergency contraception). There was non-statistically significant increased rate of pregnancy among Chinese women in the Plan One-Step trial. The reason for this apparent increase in the pregnancy rate with emergency contraceptives in Chinese women is unknown [see USE IN SPECIFIC POPULATIONS (8.6)]. Hepatic ImpairmentNo formal studies were conducted to evaluate the effect of hepatic disease on the disposition of Plan One-Step.Renal ImpairmentNo formal studies were conducted to evaluate the effect of renal disease on the disposition of Plan One-Step.Drug-Drug InteractionsNo formal drug-drug interaction studies were conducted with Plan One-Step [see DRUG INTERACTIONS (7)].

CLINICAL STUDIES SECTION.


14 CLINICAL STUDIES. double-blind, randomized, multicenter, multinational study evaluated and compared the efficacy and safety of three different regimens for emergency contraception. Subjects were enrolled at 15 sites in 10 countries; the racial/ethnic characteristics of the study population overall were 54% Chinese, 34% Caucasian, and 12% Black or Asian (other than Chinese). 2,381 healthy women with mean age of 27 years, who needed emergency contraception within 72 hours of unprotected intercourse were involved and randomly allocated into one of the two levonorgestrel groups. single dose of 1.5 mg of levonorgestrel (Plan One-Step) was administered to women allocated into group 1. Two doses of 0.75 mg levonorgestrel 12 hours apart (Plan B) were administered to women in group 2. In the Plan One-Step group, 16 pregnancies occurred in 1,198 women and in the Plan group, 20 pregnancies occurred in 1,183 women. The number of pregnancies expected in each group was calculated based on the timing of intercourse with regard to each womans menstrual cycle. Among women receiving Plan One-Step, 84% of expected pregnancies were prevented and among those women taking Plan B, 79% of expected pregnancies were prevented. The expected pregnancy rate of 8% (with no contraceptive use) was reduced to approximately 1% with Plan One-Step.Emergency contraceptives are not as effective as routine contraception since their failure rate, while low based on single use, would accumulate over time with repeated use [see INDICATIONS AND USAGE (1)].In the clinical study, bleeding disturbances were the most common adverse event reported after taking the levonorgestrel-containing regimens. More than half of the women had menses within two days of the expected time; however, 31% of women experienced change in their bleeding pattern during the study period; 4.5% of women had menses more than days after the expected time.
