Ethinyl estradiol; ferrous fumarate; norethindrone Market Analysis and Financial Projection

Market Dynamics and Financial Trajectory for Ethinyl Estradiol, Ferrous Fumarate, and Norethindrone

Introduction

The combination of ethinyl estradiol, ferrous fumarate, and norethindrone is a widely used oral contraceptive, marketed under various brand names such as LO LOESTRIN FE, Femcon® Fe, and others. This article delves into the market dynamics and financial trajectory of these drugs, highlighting their target markets, marketing strategies, financial performance, and future outlook.

Target Market

Demographics

The primary target market for these oral contraceptives is young millennial women aged 18 to 24 who are either starting birth control for the first time or switching from other methods. This demographic is crucial due to their high likelihood of being sexually active and seeking effective, convenient, and safe birth control options[3].

Psychographics

These women are often health-conscious, tech-savvy, and highly influenced by social media and online health resources. Marketing strategies therefore focus on connecting with this demographic through humor, real-world scenarios, and bold messaging across various media channels[3].

Marketing Strategies

Campaigns and Promotions

Allergan, the developer of LO LOESTRIN FE, has implemented effective marketing strategies, including the "Women Who Know" campaign. This campaign is featured across TV, print, and digital platforms, and is promoted through outlets like Refinery29, Instagram, Bravo!, HGTV, and Cosmopolitan. Such campaigns aim to increase brand awareness and engagement among the target demographic[3].

Product Differentiation

LO LOESTRIN FE differentiates itself by having the lowest dose of estrogen among oral contraceptives, which is a key selling point. This unique feature appeals to women who are concerned about the potential side effects associated with higher estrogen levels[3].

Financial Performance

Quarterly and Annual Revenue

LO LOESTRIN FE has demonstrated significant revenue growth. In the fourth quarter of 2019, it generated net revenues of $156.2 million, representing an 8.6% increase compared to the same quarter in the previous year. For the full year 2019, it continued to be a major revenue driver for Allergan's women's health business. In the first quarter of 2018, LO LOESTRIN FE brought in $114 million, a 14% increase over the first quarter of 2017, despite a 33% decline in Allergan's overall women's health business during the same period[3].

Market Impact and Sales Trends

The shift in promotional focus from LOESTRIN 24 FE to LO LOESTRIN FE, starting in early 2011, significantly impacted sales. While LOESTRIN 24 FE saw a decline in net sales and filled prescriptions, LO LOESTRIN FE generated $33 million in net sales in the quarter ended September 30, 2012, and continued to be the primary focus of Allergan's women's healthcare sales efforts[3].

Competitive Landscape

Other Products

Other products containing the combination of norethindrone and ethinyl estradiol, such as Femcon® Fe and Ovcon-35, also compete in the market. These products have similar indications but may differ in dosage and regimen. For example, Femcon® Fe contains 0.4 mg norethindrone and 35 mcg ethinyl estradiol, and is taken once daily for 21 days followed by one tablet of ferrous fumarate once daily for seven days[1][2].

Regulatory and Patent Landscape

Patent Protection

LO LOESTRIN FE is protected by one patent, with nine patent family members in seven countries. There is one Paragraph IV patent challenge, which may lead to patent invalidation or a license for generic production. This could potentially impact the market dynamics and financial trajectory of the drug in the future[3].

Clinical and Safety Profile

Mechanism of Action

The combination of ethinyl estradiol and norethindrone works by suppressing gonadotropins, primarily inhibiting ovulation. Additionally, it alters cervical mucus and the endometrium, making it more difficult for sperm to enter the uterus and reducing the likelihood of implantation[2].

Pharmacokinetics

Ethinyl estradiol and norethindrone are rapidly absorbed, with maximum plasma concentrations occurring within 2 hours. They are excreted in both urine and feces, primarily as metabolites. The mean terminal elimination half-lives are approximately 9 hours for norethindrone and 17 hours for ethinyl estradiol[2].

Safety Considerations

The safety profile of these drugs has been demonstrated in clinical trials, with no new or unexpected safety concerns raised. However, the effects of renal and hepatic insufficiency on the disposition of these drugs have not been fully evaluated. In patients with impaired liver function, ethinyl estradiol and norethindrone may be poorly metabolized[2].

Future Outlook

Given its strong financial performance, unique selling points, and effective marketing strategies, LO LOESTRIN FE is poised to continue as a significant player in the oral contraceptive market. Ongoing efforts to make the product more affordable and accessible through savings programs will likely sustain its growth trajectory.

"Encouraging women to be aware of the pill they are prescribed – the same way we’ve grown hyper aware of the foods that we eat, we also need to be aware of what’s in the pill, and how it can affect us," - Cindy Schwartz, Associate VP of Marketing at Allergan Women’s Healthcare[3].
