Market Dynamics and Financial Trajectory for Wixela Inhub
Introduction
Wixela Inhub, developed by Mylan (now part of Viatris), is the first FDA-approved generic equivalent of ADVAIR DISKUS, a widely used treatment for asthma and chronic obstructive pulmonary disease (COPD). This article delves into the market dynamics and financial trajectory of Wixela Inhub, highlighting its impact on the pharmaceutical industry and patient access to affordable treatments.
Market Need and Competition
The approval of Wixela Inhub addresses a significant market need by providing a more affordable alternative to ADVAIR DISKUS. ADVAIR DISKUS had substantial sales, with U.S. sales reaching $4.2 billion for the 12 months ending November 30, 2018[1].
Regulatory Approval and Therapeutic Equivalence
Wixela Inhub received FDA approval in January 2019, marking a significant milestone in the development of generic respiratory treatments. The FDA approval was based on extensive clinical trials that demonstrated the therapeutic equivalence of Wixela Inhub to ADVAIR DISKUS. These trials included a 28-day, randomized, double-blind, placebo-controlled study involving 1,128 adult asthma patients, which showed equivalent efficacy and safety profiles between the two treatments[1][4].
Launch and Availability
Following FDA approval, Wixela Inhub was launched in the second half of February 2019 in the U.S. and later in Canada in March 2020. The drug is available in various strengths: 100 mcg/50 mcg, 250 mcg/50 mcg, and 500 mcg/50 mcg for asthma patients, and 250 mcg/50 mcg and 500 mcg/50 mcg for COPD patients[1][4].
Research and Development Investment
The development of Wixela Inhub was a result of a substantial investment of over $700 million, reflecting Mylan's commitment to expanding patient access to complex treatment options. This investment included an extensive research and development program that spanned over a decade and involved close collaboration with the FDA to define the regulatory pathway[1][4].
Market Impact
The introduction of Wixela Inhub has significantly impacted the market by providing patients with a lower-cost alternative to ADVAIR DISKUS. This has been particularly beneficial for patients with asthma and COPD, who often rely on long-term treatment with these medications. The availability of a generic option has helped in reducing healthcare costs and increasing patient access to essential treatments[1].
Financial Performance
The financial performance of Wixela Inhub has been a key factor in Viatris's overall financial trajectory. Despite managing competition, complex generics and biosimilars, including Wixela Inhub, delivered strong growth. In the fourth quarter and full year of 2021, Viatris reported that generics performed better than expected, driven by favorability in certain markets[2][5].
- Revenue Contribution: Wixela Inhub has contributed to Viatris's revenue growth, particularly in the generics segment. For instance, in 2021, Viatris reported net sales of $4,331.3 million, with generics contributing significantly to this figure[2].
- Gross Profit and Margin: The adjusted gross profit and margin for Viatris's generics segment, which includes Wixela Inhub, have shown improvement. In 2021, the adjusted gross margin was 56.6%, indicating a strong financial performance[2][5].

Challenges and Competition
While Wixela Inhub has been successful, it faces competition from other generic and branded inhalers. Managing this competition has been a challenge, but Viatris has continued to execute its strategy to maintain market share. The company has also navigated regulatory changes and updates, such as the incorporation of new safety information required by the FDA[1][2].
Patient and Healthcare Provider Response
Patients and healthcare providers have welcomed Wixela Inhub as a viable and cost-effective alternative to ADVAIR DISKUS. Clinical trials and real-world use have shown that patients find Wixela Inhub easy to use and highly effective in controlling their asthma. This positive response has been echoed by specialists and primary care providers, who see the generic option as a significant benefit for many patients[1].
Global Expansion
Mylan's global reach has facilitated the expansion of Wixela Inhub beyond the U.S. and Canada. The company's commitment to providing high-quality medicines to over 7 billion people worldwide aligns with its mission to increase access to affordable treatment options globally[4].
