BASEL, Switzerland I January 09, 2018 I Axovant Sciences (NASDAQ:AXON) today announced a correction to the data related to the Company’s investigational drug nelotanserin previously reported in its January 8, 2018 press release. In the results of the pilot Phase 2 Visual Hallucination study, the post-hoc subset analysis of patients with a baseline Scale for the Assessment of Positive Symptoms - Parkinson's Disease (SAPS-PD) score of greater than 8.0 was misreported. The previously reported data for this population (n=19) that nelotanserin treatment at 40 mg for two weeks followed by 80 mg for two weeks resulted in a 1.21 point improvement (p=0.011, unadjusted) were incorrect. While nelotanserin treatment at 40 mg for two weeks followed by 80 mg for two weeks did result in a 1.21 point improvement, the p-value was actually 0.531, unadjusted. Based on these updated results, the Company will continue to discuss a larger confirmatory nelotanserin study with the U.S. Food and Drug Administration (FDA) that is focused on patients with dementia with Lewy bodies (DLB) with motor function deficits. The Company may further evaluate nelotanserin for psychotic symptoms in DLB and Parkinson’s disease dementia (PDD) patients in future clinical studies.
About the Nelotanserin Visual Hallucinations Study
This multi-center, randomized, double-blind, placebo-controlled, pilot Phase 2 crossover study evaluated the safety, tolerability, and efficacy of nelotanserin over a four-week treatment period and enrolled 30 patients with DLB and PDD who were experiencing frequent and recurrent visual hallucinations. With the crossover design, every patient received placebo for four weeks and nelotanserin for four weeks (two weeks of a 40 mg dose followed by two weeks of an 80 mg dose). Study participants were allowed to be on stable antipsychotic treatments, stable anti-Parkinson’s disease treatments, and stable background cholinesterase inhibitor therapy for at least four weeks prior to screening.
The prespecified primary endpoint of the pilot study was safety including assessment of extrapyramidal symptoms as measured by the change in UPDRS scores. In addition, there were multiple exploratory efficacy assessments in the study that included UPDRS Part III, SAPS, SAPS-PD, PGIC-VH and an internally developed patient diary, that evaluated the effects of nelotanserin over a four-week treatment period. Individuals who completed this study were eligible to receive nelotanserin in an extension study.
Dementia with Lewy bodies (DLB) is a progressive neurodegenerative disorder characterized by the aggregation of Lewy bodies, abnormal deposits of a protein called alpha-synuclein. Lewy bodies build up in areas of the brain that regulate behavior, cognition and movement. DLB is the second most prevalent cause of neurodegenerative dementia in elderly patients. Approximately 1.1 million patients in the United States have DLB. Patients with DLB can present with a range of symptoms including fluctuations in cognition, attention and alertness; Parkinson’s symptoms; visual hallucinations; and REM sleep behavior disorder (RBD), in which people physically act out their dreams, impacting their quality of life and endangering their bed partners. No therapies are approved for the treatment of DLB in the United States or Europe.i
Nelotanserin is a selective inverse agonist of the 5-HT2A receptorii that was discovered by Arena Pharmaceuticals, Inc.
