Allergan to Acquire Glaucoma Treatment Company AqueSys

Pharma company Allergan plc, is to acquire AqueSys, Inc. in an all-cash transaction for a $300 million upfront payment and regulatory approval and commercialization milestone payments.


Glaucoma is a group of diseases that damage the eye’s optic nerve and can result in vision loss and blindness. To reduce intraocular pressure, AqueSys’ XEN45 is a soft shunt, implanted in the subconjunctival space in the eye through a minimally invasive procedure with a single use, pre-loaded proprietary injector(pictured). The proprietary XEN45 technology facilitates aqueous fluid flow to lower Intra-Ocular Pressure (IOP) while protecting against the potential for hypotony (IOP that is too low) that is associated with current subconjunctival procedures.

XEN45 has received a CE mark in the European Union where it is indicated for the reduction of intraocular pressure in patients with primary open angle glaucoma where previous medical treatments have failed. The CE mark allows treatment in conjunction with a cataract procedure or as a standalone procedure. XEN45 is also approved for use in Turkey, Canada and Switzerland. AqueSys is pursuing reimbursement in these countries. In the United States, XEN45 is in late-stage development, with the final US Investigational Device Exemption (IDE) clinical trial fully enrolled in the second quarter of 2015. Final approval by the U.S. Food and Drug Administration is expected by late 2016 or early 2017 via the 510K device pathway.

Pending approvals, Allergan anticipates closing the transaction in the fourth quarter of 2015.

Physician comments

“The XEN45 platform is a minimally invasive reinvention of the sub-conjunctival outflow approach to the treatment of glaucoma, one used for many years by surgeons,” said Robert N. Weinreb, M.D., Distinguished Professor of Ophthalmology and Director of the Shiley Eye Institute at the University of California San Diego. “XEN45 provides the advantage of a simpler and less invasive way of conducting a well-established procedure to treat our glaucoma patients, and if approved in the U.S., would provide an exciting new option for ophthalmologists.”

The acquisition of the XEN45 device demonstrates our commitment to alternative next-generation glaucoma treatments which are appealing to both patients and physicians and extend beyond conventional medication eyedrops.”

“The XEN45 program has been shown to provide a robust efficacy profile with minimal side effects, and if approved in the U.S., would provide an exciting new treatment option for patients, and one that is highly complementary to our ongoing portfolio and development programs in this critical treatment area,” said David Nicholson, EVP and President, Global Brands Research and Development at Allergan.

“With its pedigree in the eye care space, its deep commercial network in eye care professional communities, and its commitment to being a leading provider of treatments for glaucoma, Allergan was a natural fit and a compelling partner for us to maximize the potential for the XEN45 technology platform,” said Ron Bache, CEO of AqueSys. “The addition of the XEN45 technology to Allergan’s world-class eye care development and commercialization organization will propel the potential use of this best-in-class technology by global ophthalmologists and the patients that they treat.”
