(IRVINE, Calif., June 30, 2014) — Allergan, Inc. (NYSE: AGN) (“Allergan” or the “Company”) today announced updates on three of the Company’s key R&D pipeline programs, including abicipar pegol (Anti-VEGF DARPin^®), bimatoprost sustained-release implant for glaucoma and SEMPRANA™ (dihydroergotamine) inhalation aerosol (formerly referred to as LEVADEX^®). In addition, Allergan announced that it has received approval from the U.S. Food and Drug Administration (FDA) for OZURDEX^® (dexamethasone intravitreal implant) 0.7 mg as a treatment option for diabetic macular edema (DME) in adult patients who have an artificial lens implant (pseudophakic) or who are scheduled for cataract surgery (phakic).

“Allergan has a long track record of delivering stockholder value by efficiently investing in R&D to provide important new treatment options to address unmet patient needs,” said David E.I. Pyott, Chairman and Chief Executive Officer, Allergan. “As a company that is well-known for industry leading R&D and innovation, we are pleased to announce the FDA approval of OZURDEX^®, which marks our 12^th FDA approval since 2010. In addition, we are pleased to share updates on several of our key R&D pipeline programs including abicipar pegol (Anti-VEGF DARPin^®), which has been recognized as the most important value driver in our pipeline. With one of the most productive R&D pipelines in the industry, we are committed to advancing our R&D programs as we continue to deliver a steady stream of new treatments across the five specialty areas of our broad and balanced portfolio.”

Anti-VEGF DARPin^®

Allergan has completed the topline analysis of data from the Company’s Stage 3, Phase 2 study of abicipar pegol (Anti-VEGF DARPin^®) in neovascular, or “wet,” age-related macular degeneration (AMD). These data along with data from previous studies were reviewed with the FDA at an end of a Phase 2 meeting where the FDA supported Allergan’s decision to advance abicipar pegol to Phase 3 clinical trials and agreed with the proposed Phase 3 study plan.

The abicipar pegol Stage 3, Phase 2 study was designed to, in addition to assessing safety and efficacy, determine the appropriate dose of abicipar pegol that would provide equal or better visual acuity improvement but require less frequent injections than ranibizumab (LUCENTIS^®). In the double-masked trial, a total of 64 patients were randomized to abicipar pegol 1mg (n=25), abicipar pegol 2mg (n=23) or ranibizumab 0.5mg (n=16) and were followed for 20 weeks. All patients received doses at the start of the trial and at 4 and 8 weeks. Patients in the ranibizumab arm of the study received additional doses at 12 and 16 weeks. Patients who were treated with either dose of abicipar pegol received sham injections at 12 and 16 weeks. Patients in all arms of the study were well matched for demographics and baseline characteristics.

The analysis of the topline data showed that after 16 weeks, mean visual acuity improvement from baseline was 8.2 letters for abicipar pegol 2mg, 6.3 letters for abicipar pegol 1mg, and 5.3 letters for ranibizumab. After 20 weeks, (12 weeks after the last abicipar injection and 4 weeks after the last ranibizumab injection) mean visual acuity improvement from baseline was 9.0 letters for abicipar pegol 2mg, 7.1 letters for abicipar pegol 1mg, and 4.7 letters for ranibizumab. In addition, Optical Coherence Tomography (OCT) data was supportive of the visual acuity data. Although the study was not powered to show statistically significant differences between treatment groups, and further data will be completed and submitted to the FDA, these data suggest that abicipar at the 2mg dose is at least as effective as monthly ranibizumab with a longer duration of action.

There were no serious adverse events reported in any study group. Two patients in the abicipar pegol 2mg arm and three patients in the abicipar pegol 1mg group experienced ocular inflammation adverse events. The complete data from the Stage 3, Phase 2 study will be presented at a retina meeting in the second half of 2014.

Allergan has been working to enhance the manufacturing process for abicipar pegol and will initiate Phase 3 studies in the second quarter of 2015, when material from the new manufacturing process is

available. In the phase 3 program, Allergan will compare abicipar 2mg dosed every 8 weeks, abicipar 2mg dosed every 12 weeks and ranibizumab dosed every 4 weeks. All patients in the phase 3 program will receive three loading doses of drug.

Bimatoprost Sustained-Release Implant

Allergan has reviewed data from its Phase 2 clinical trials of bimatoprost sustained-release implant for the treatment of elevated intraocular pressure and glaucoma. Patients in this trial received a bimatoprost sustained-release implant in one eye and topical bimatoprost in the contralateral eye. The data suggests that bimatoprost sustained-release implant efficacy is comparable to daily topical bimatoprost with duration of 4-6 months.

Allergan has shared the bimatoprost sustained-release implant data with the FDA and the FDA is supportive of the company’s decision to advance to Phase 3 clinical trials. The Phase 3 clinical trials will be initiated by the end of 2014. If approved, the bimatoprost sustained-release implant may have the potential to change the treatment paradigm for patients who currently rely on daily topical eye drops to treat their condition.

OZURDEX^® (dexamethasone intravitreal implant) 0.7 mg

Allergan has received approval from the FDA for OZURDEX^® as a new treatment option for diabetic macular edema (DME) in adult patients who have an artificial lens implant (pseudophakic) or who are scheduled for cataract surgery (phakic). OZURDEX^® is a sustained-release biodegradable steroid implant that demonstrated long-term efficacy without the need for monthly injections.¹

DME currently impacts more than 560,000 Americans.² It is an eye condition that can occur in people with diabetes (types 1 and 2) and causes fluid to leak into the part of the eye where focusing occurs (macula), causing blurred vision, vision loss and eventual blindness.³ The OZURDEX^® implant uses the proprietary and innovative NOVADUR^® solid polymer delivery system – a biodegradable implant that releases medicine over an extended period of time – to suppress inflammation, which plays a key role in the development of DME.¹

“The approval of OZURDEX^® for certain patients with DME further strengthens Allergan’s leadership position in ophthalmology and the retina subspecialty,” said Scott M. Whitcup, M.D., Executive Vice President, Research and Development and Chief Scientific Officer, Allergan. “In addition to receiving this

important FDA approval, we are also pleased that two of our innovative pipeline programs are advancing to Phase 3 clinical development. These therapies involve novel molecules or innovative drug delivery systems which may help to improve patient outcomes.”

SEMPRANA™ (dihydroergotamine), formerly LEVADEX^®

Allergan has received a Complete Response Letter (CRL) from the FDA to its New Drug Application (NDA) for SEMPRANA^™ (dihydroergotamine), formerly referred to as LEVADEX^®, which is being developed as an acute treatment of migraine in adults. In the CRL, the FDA acknowledged that Allergan has made improvements in the canister filling process.

The two specific items listed in the CRL are related to specifications around content uniformity on the improved canister filling process and on standards for device actuation. There were no issues related to the clinical safety and efficacy of the product and Allergan received draft labeling from the FDA for the product in June 2013. Allergan plans to meet with the FDA and will work to fully address these issues to the satisfaction of the FDA. The Company estimates that the next FDA action will occur by the end of the second quarter of 2015.

FDA Approved Uses for OZURDEX^® (dexamethasone intravitreal implant) 0.7 mg

OZURDEX^® (dexamethasone intravitreal implant) is a prescription medicine that is an implant injected into the eye (vitreous) and used:

IMPORTANT SAFETY INFORMATION

OZURDEX^® should not be used if you have any infections or diseases in the eye, or surrounding eye area, including most viral diseases of the cornea and conjunctiva, including active herpes viral infection of the eye, vaccinia, varicella, mycobacterial infections, and fungal diseases.

OZURDEX^® should not be used if you have advanced glaucoma.

OZURDEX^® should not be used if you have a posterior lens capsule that is not intact.

You should not use OZURDEX^® if you are allergic to any of its ingredients.

Injections into the vitreous in the eye, including those with OZURDEX^®, are associated with serious eye infection (endophthalmitis), eye inflammation, increased eye pressure, and retinal detachments. Your eye doctor may monitor you regularly after the injection.

Use of corticosteroids may produce posterior subcapsular cataracts, increased eye pressure, glaucoma, and may increase the establishment of secondary eye infections due to bacteria, fungi, or viruses. Let your doctor know if you have a history of ocular herpes simplex.

There may be a risk of the implant moving into the front chamber of the eye if you had the posterior capsule of the lens removed or if you have a tear in the capsule.

The most common side effects reported in patients for retinal vein occlusion and uveitis include: increased eye pressure, conjunctival blood spot, eye pain, eye redness, ocular hypertension, cataract, vitreous detachment, and headache.

The most common side effects reported in patients with diabetic macular edema include: cataract, increased eye pressure, conjunctival blood spot, reduced vision, inflammation of the conjunctiva, specks that float in the field of vision, swelling of the conjunctiva, dry eye, vitreous detachment, vitreous opacities, retinal aneurysm, foreign body sensation, corneal erosion, inflammation of the cornea, anterior chamber inflammation, retinal tear, drooping eyelid and high blood pressure.

After repeated injections with OZURDEX^®, a cataract may occur. If this occurs, your vision will decrease and you will need an operation to remove the cataract and restore your vision. You may develop increased eye pressure with OZURDEX^® that will need to be managed with eye drops, and rarely, with surgery.

In the days following injection with OZURDEX^®, you may be at risk for potential complications including in particular, but not limited to, the development of serious eye infection or increased eye pressure. If your eye becomes red, sensitive to light, painful, or develops a change in vision, you should seek immediate care from your eye doctor. You may experience temporary visual blurring after receiving an injection and should not drive or use machinery until your vision has resolved.
