Glaukos Corporation GKOS is well-poised for growth, backed by favorable clinical trial results and a robust product pipeline. However, stiff competition remains a concern.Shares of this Zacks Rank #3 (Hold) have gained 6.3% against the industry’s decline of 29.2% on a year-to-date basis. The S&P 500 Index has fallen 18.3% in the same time frame.Glaukos — with a market capitalization of $2.25 billion — is a leading ophthalmic medical technology and pharmaceutical company.

The company has a trailing negative four-quarter earnings surprise of 7.6%, on average.Image Source: Zacks Investment ResearchKey CatalystsClinical trials are the primary means to evaluate the efficacy and safety of new medical technologies.Glaukos launched iPrime — a new disco elastic delivery device — in the latter part of the second quarter. In the latter part of the first quarter, the company had launched the iAccess device for go anatomy procedures. The addition of these new devices will provide unique solutions designed to grow and improve treatment options for surgeons, customers and patients. The company’s iAccess device received positive market feedback.In August, Glaukos received clearance from the FDA for the commercialization of iStent infinite as an implantable device intended to reduce the intraocular pressure (IOP) of the eye in adult patients with primary open-angle glaucoma in whom previous medical and surgical treatment failed. The company plans to launch the product during the fourth quarter.In September, Glaukos announced that its targeted injectable implant candidate — iDose TR — for glaucoma patients achieved excellent tolerability and a favorable safety profile, per top-line data from two pivotal studies. The candidate achieved non-inferior reductions in IOP in three months from baseline compared to the timolol ophthalmic solution. Based on these data, the company is planning to file a new drug application (NDA), seeking approval for iDose TR from the FDA by the end of 2023. A potential approval for the candidate will substantially boost revenues for Glaukos.The company is also developing three other candidates — GLK-301, GLK-302 and third-generation iLink therapy — in separate phase II studies as a potential treatment for Dry Eye Disease, presbyopia and keratoconus, respectively.These positive developments raise our optimism about the stock.Glaukos’s better-than-expected revenues and earnings in the third quarter were also encouraging.Factor Hurting the StockGlaukos’ competitors include medical companies, academic and research institutions, and others that develop new drugs, therapies, medical devices or surgical procedures to treat glaucoma.
