Introduction to Combigan
Combigan is a prescription eye drop approved for reducing elevated intraocular pressure (IOP) in patients with glaucoma or ocular hypertension. It is a fixed-dose combination product containing brimonidine tartrate 0.2% and timolol maleate 0.5%, developed and marketed by Allergan[4].
Market Context
The global glaucoma therapeutics market is experiencing significant growth, driven primarily by the increasing prevalence of glaucoma, particularly in aging populations. By 2027, the global glaucoma therapeutics market is projected to reach $11.05 billion, growing at a compound annual growth rate (CAGR) of 6.1% from 2019 to 2027[3].
Current Market Position
Combigan, approved in October 2007, is one of the key players in the glaucoma treatment market. It combines the efficacy of two older IOP agents, Alphagan (brimonidine tartrate) and Timoptic (timolol maleate), offering a two-pronged approach to reduce IOP. This combination has been shown to provide an additional IOP-lowering effect compared to the separate use of these drugs[4].
Sales Projections and Market Trends
Historical Performance
In the past, Combigan has been a significant contributor to the glaucoma treatment market. However, its sales have been influenced by various market dynamics. For instance, the introduction of new products and the loss of patent protection for existing drugs can impact sales.
Future Outlook
The glaucoma treatment market is expected to see sustained growth due to the introduction of new products and the increasing prevalence of glaucoma. However, Combigan's sales are anticipated to face challenges:
- Patent Expiration: Allergan will lose patent protection for Combigan (brimonidine and timolol) in 2022, which could lead to increased competition from generic versions and impact sales[1].
- Market Competition: The market will see the introduction of new fixed-dose combination (FDC) products, such as Roclatan (a prostaglandin analog-containing FDC), which is expected to achieve high sales and become a market driver[1].
Regional Performance
The United States is the dominant market for glaucoma treatments, and Combigan has a significant presence here. However, the overall market share of the U.S. is expected to rise slightly from 70.7% to 71.6% between 2013 and 2023, driven by the introduction of new products and an aging population[1].
Efficacy and Tolerability
Combigan's marketing strategy focuses on its efficacy and tolerability. Clinical studies have shown that Combigan, dosed twice daily, provides an additional IOP-lowering effect compared to the separate use of brimonidine and timolol. However, the IOP-lowering effect of Combigan is less than that seen with the concomitant administration of timolol and brimonidine at different dosing frequencies[4].
Adverse Reactions and Safety Profile
The most commonly observed adverse reactions associated with Combigan include somnolence and reduced alertness, particularly in pediatric patients using brimonidine tartrate as adjunctive therapy to beta-blockers[4].
Competitive Landscape
The glaucoma therapeutics market is highly competitive, with major players such as Novartis AG, Pfizer, Inc., and AbbVie Inc. The launch of new products by these market players is expected to drive the adoption of glaucoma therapeutics. For example, the introduction of Roclatan, a prostaglandin analog-containing FDC, is anticipated to generate significant sales and market share[3].
