1 INDICATIONS AND USAGE TWIRLA is indicated as a method of contraception for use in women of reproductive potential with a BMI < 30 kg/m 2 for whom a combined hormonal contraceptive is appropriate.

Limitation of Use Consider TWIRLA’s reduced effectiveness in women with a BMI ≥ 25 to < 30 kg/m 2 before prescribing TWIRLA [see Use in Specific Populations ( 8.9 ) and Clinical Studies ( 14 )] .

TWIRLA is contraindicated in women with a BMI ≥ 30 kg/m 2 [see Contraindications ( 4 )] .

TWIRLA is a combination of levonorgestrel, a progestin, and ethinyl estradiol, an estrogen, indicated as a method of contraception for use in women of reproductive potential with a BMI < 30 kg/m 2 for whom a combined hormonal contraceptive is appropriate.

( 1 ) Limitation of Use Consider TWIRLA’s reduced effectiveness in women with a BMI ≥ 25 to < 30 kg/m 2 before prescribing.

6 ADVERSE REACTIONS The following serious adverse reactions with the use of CHCs, including TWIRLA, are discussed elsewhere in the labeling: Thromboembolic Disorders and Other Vascular Conditions [see Warnings and Precautions ( 5.1 )] Liver disease [see Warnings and Precautions ( 5.3 )] The most common adverse reactions (≥ 2%) in clinical trials for TWIRLA are application site disorders, nausea, headache, dysmenorrhea, and increased weight.

6.1 Clinical Trial Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of one product cannot be directly compared to rates in the clinical trials of another product and may not reflect the rates observed in practice.

The safety of TWIRLA was evaluated in a 12-month, multicenter, open-label, single-arm clinical trial (NCT02158572) conducted in the United States [see Clinical Studies ( 14 )] .

Women applied TWIRLA (120 mcg LNG/30 mcg EE) for 13 28-day treatment cycles.

One treatment cycle is defined as three consecutive weeks that one TWIRLA TDS is applied for seven-day wear followed by one week that TWIRLA is not applied.

The safety population for this clinical trial was composed of 2,031 women that contributed 18,841 treatment cycles of exposure.

Of these 2,031 women, 989 women completed 13 treatment cycles.

The mean age was 27.5 years.

The mean BMI for the safety population was 28.3 kg/m 2 .

The BMI of the safety population was widely distributed: 39.4% had a BMI < 25 kg/m 2 , 25.3% had a BMI ≥ 25 kg/m 2 and < 30 kg/m 2 , and 35.3% had a BMI ≥ 30 kg/m 2 .

For women who received TWIRLA, the most common reasons for discontinuation from the study were a womans decision (15.3%) and lost to follow-up (11.3%).

Discontinuation due to an adverse reaction occurred in 10.9% of women.

The most common (≥ 2%) adverse reactions leading to discontinuation were application site disorder (3.1%) and any bleeding irregularities (2.2%).

The most common adverse reactions that occurred in ≥ 2% of the 2,031 women that used TWIRLA are shown in Table 3.

Table 3: Adverse Drug Reactions Reported by 2% of TWIRLA-Treated Women in One Phase 3 Clinical Trial Adverse reaction TWIRLA (n=2,031) General disorders and administration site conditions Application site disorder Represents a bundle of similar terms that include the following adverse reactions: application site acne, hemorrhage, pustules, dermatitis, hypersensitivity, rash, discoloration, induration, reaction, dryness, irritation, ulcer, erosion, pain, urticaria, erythema, papules, vesicles, exfoliation, pruritis.

6.2% Gastrointestinal disorders Nausea 4.1% Nervous system disorders Headache 3.6% Reproductive system and breast disorder Dysmenorrhoea 2.3% Investigations Weight increased 2.0% Venous Thromboembolic Events (VTEs) A total of four VTEs (including pulmonary embolism and deep vein thrombosis) in TWIRLA-treated patients were identified in the clinical trial.

Of these, all were in women with a BMI > 30 kg/m 2 [see Contraindications ( 4 )] .

Other Serious Adverse Reactions The following serious adverse reactions occurred in < 1% of women who received TWIRLA: cholelithiasis, cholecystitis, major depression, suicidal ideation, appendicitis, ectopic pregnancy, pneumonia, and gastroenteritis.

6.2 Postmarketing Experience Five studies that compared breast cancer risk between ever-users (current or past use) of combined oral contraceptives (COCs) and never-users of COCs reported no association between ever use of COCs and breast cancer risk, with effect estimates ranging from 0.90 - 1.12 (Figure 2).

Three studies compared breast cancer risk between current or recent COC users (<6 months since last use) and never users of COCs (Figure 2).

One of these studies reported no association between breast cancer risk and COC use.

The other two studies found an increased relative risk of 1.19 - 1.33 with current or recent use.

Both of these studies found an increased risk of breast cancer with current use of longer duration, with relative risks ranging from 1.03 with less than one year of COC use to approximately 1.4 with more than 8-10 years of COC use.

Relevant Studies of Risk of Breast Cancer with Combined Oral Contraceptives RR = relative risk; OR = odds ratio; HR = hazard ratio.

“ever COC” are females with current or past COC use; “never COC use” are females that never used COCs.
