Axovant Announces Expansion of Dementia Drug Development Pipeline and Reports Financial Results for the Second Fiscal Quarter and Six Months Ended September 30, 2015

HAMILTON, Bermuda, Nov. 2, 2015 /PRNewswire/ -- Axovant Sciences Ltd. (NYSE: AXON), a leading clinical-stage biopharmaceutical company focused on the treatment of dementia, today announced an expansion of its dementia drug development pipeline with the acquisition of nelotanserin and the addition of three new clinical programs to address cognitive, behavioral and functional aspects of Lewy body dementia, a disease affecting approximately 1.4 million people in the U.S. The Company also provided an update on its ongoing Phase 3 development program for RVT-101 to treat Alzheimer's disease. In addition, the Company reported financial results for the second fiscal quarter and first half of 2015.

"Consistent with our mission, we have expanded our development pipeline in a capital-efficient manner that we believe will enable Axovant to create value for patients and our shareholders," stated Vivek Ramaswamy, Chief Executive Officer of Axovant Sciences, Inc. "The acquisition of global rights to nelotanserin and the addition of a development program for RVT-101 in dementia with Lewy bodies should lead to multiple value-creating catalysts in 2016 and help establish Axovant as the global leader in the treatment of Lewy body dementia."

Dr. James Leverenz, Chair, Scientific Advisory Council of the Lewy Body Dementia Association and Director of the Cleveland Lou Ruvo Center for Brain Health at the Cleveland Clinic, stated, "Pharmaceutical companies have historically neglected Lewy body dementia despite its status as the second leading degenerative cause of dementia, next to Alzheimer's disease. The new development programs for RVT-101 and nelotanserin represent an important and promising step towards addressing this devastating disease, and I look forward to the progress of these exciting innovations in the field."

Acquisition of Global Rights to Nelotanserin
In October 2015, Axovant exercised its option to acquire global rights to nelotanserin from its parent company, Roivant Sciences Ltd. (RSL). RSL had previously acquired the global rights from Arena Pharmaceuticals, GmbH (Arena).

After exercising the option, Axovant paid RSL approximately $4.8 million, which includes reimbursements for amounts paid to date by RSL to Arena. Under the development, marketing and supply agreement to which Axovant is now a party, Arena is eligible to receive future payments from Axovant of up to an aggregate of $101.5 million based on the achievement of specified developmental, regulatory and commercial milestone events. Under the agreement, Arena will be the sole and exclusive manufacturer of nelotanserin for both clinical and commercial supply and will provide finished drug product to Axovant from Arena's qualified manufacturing facility in Switzerland for a price equal to 15 percent of Axovant's net sales of nelotanserin.

Axovant intends to initiate two Phase 2 clinical studies with nelotanserin in the first quarter of 2016. The first study will be in patients with either dementia with Lewy bodies (DLB) or Parkinson's disease dementia (PDD) who suffer from visual hallucinations. The second study will be in DLB patients experiencing REM Behavior Disorder (RBD).

Axovant also intends, pending additional data available in 2016, to initiate programs for nelotanserin in Alzheimer's disease psychosis and Parkinson's disease psychosis.

Dominic Behan, Ph.D., D.Sc., Chief Scientific Officer and Co-Founder of Arena, commented, "We are excited to work with Axovant to bring this potentially best-in-class 5HT_2A inverse agonist to market. We chose Axovant's team based on their clear leadership in the field of dementia. The impressive development plans that Dr. Larry Friedhoff and his team have created reaffirms our belief that working with Axovant will give nelotanserin the best opportunity to reach dementia patients."

RVT-101 in Dementia with Lewy Bodies Program Initiation
Axovant plans to initiate a 24-week Phase 2b study of RVT-101 as a potential treatment for DLB. The study is expected to start in the first quarter of 2016. If the results of this study are favorable, Axovant believes that the study could serve as the basis for seeking approval of RVT-101 to treat DLB patients.

RVT-101 in Alzheimer's Disease Program Update
As announced previously, in October 2015 Axovant commenced a global, multi-center, double-blind, placebo-controlled confirmatory Phase 3 study of RVT-101 for the treatment of mild-to-moderate Alzheimer's disease called the MINDSET Study.

The MINDSET Study is evaluating the safety, tolerability and efficacy of RVT-101 and seeks to confirm the results of a prior study in which patients treated with RVT-101 were observed to have statistically significant improvements in cognition and function in mild-to-moderate Alzheimer's disease patients. Subjects completing the MINDSET Study will be eligible to enroll in a 12 month open-label extension trial in which other medications for the treatment of Alzheimer's disease, including memantine and other cholinesterase inhibitors may be administered in combination with RVT-101.

Axovant has received a Special Protocol Assessment (SPA) agreement from the FDA for the MINDSET Study. The SPA agreement states that the design and planned analysis of this study adequately address the objectives necessary to support an application for marketing approval.

Axovant intends to develop a pipeline of product candidates to comprehensively address the cognitive, functional and behavioral components of dementia and related neurological disorders. Our vision is to become the leading company focused on the treatment of dementia by addressing all forms and aspects of the disease.

About RVT-101
RVT-101 is an orally administered, potent antagonist of the 5HT₆ receptor. Antagonism of the 5HT₆ receptor is a novel mechanism of action that promotes the release of acetylcholine and other neurotransmitters thought to improve cognition and function in patients suffering from Alzheimer's disease and other forms of dementia. RVT-101 has been studied in 13 clinical trials and dosed in over 1,250 human subjects with a favorable safety and tolerability profile.

RVT-101 is an investigational new drug candidate and is not approved for any indication in any markets.

About MINDSET
MINDSET is a Phase 3 international, multi-center, double-blind, placebo-controlled clinical study designed to evaluate the safety, tolerability and efficacy of RVT-101 in patients with mild-to-moderate Alzheimer's disease. The 24-week trial will compare 35-mg, once-daily oral doses of RVT-101 to placebo in approximately 1,150 patients with mild-to-moderate Alzheimer's disease on a stable background of donepezil therapy. The primary efficacy evaluations are the Alzheimer's Disease Assessment Scale - cognitive subscale (ADAS-cog) and the Alzheimer's Disease Cooperative Study - Activities of Daily Living scale (ADCS-ADL), each of which have been used as endpoints to obtain regulatory approval of currently-marketed Alzheimer's disease treatments in the United States and Europe.

The MINDSET trial is designed to confirm the results of a 684-patient Phase 2 international, multi-center, double-blind placebo-controlled study in which patients on a stable background of donepezil therapy receiving 35 mg of RVT-101 were observed to have statistically significant improvements in their ADAS-cog and ADCS-ADL scores as compared to patients receiving donepezil alone.
