Axovant Announces 6-Month Follow-Up Data From First Cohort of SUNRISE-PD Phase 2 Trial of AXO-Lenti-PD and Pipeline Update
- AXO-Lenti-PD was observed to be generally well tolerated at six months, and continued to demonstrate benefits in both patients across multiple measures after a single administration
- Totality of data across the program at 6 months supports overall favorable product profile
- Initial three-month data from second dose cohort of SUNRISE-PD Phase 2 study is expected in the fourth quarter of 2019
AXO-Lenti-PD 6-month data
“We continue to be encouraged by the consistency of the data and improvements in quality of life seen at six months in the two low-dose cohort patients, as we enroll additional patients in the second cohort of the SUNRISE-PD study,” said Dr.
At month six, the patients experienced an average improvement from baseline in UPDRS III (motor) OFF score of 17 points, representing an average improvement of 29%. Individual patient improvements at 6 months were 14 and 20 points, respectively. The patients experienced an average improvement of approximately 20 points from baseline on the UPDRS Part II (activities of daily living) OFF score, and an average improvement of 3 points from baseline on the UPDRS Part IV (complications of therapy) OFF score.
The average levodopa equivalent daily dose (LEDD) at baseline was 1117mg and at month six was 884mg, a decrease of 233 mg, or 21% from baseline. On the Rush Dyskinesia Rating Scale, at month six, patients experienced a mean 18% improvement in functional disability during activities of daily living while on oral levodopa.
The Parkinson’s Disease Questionnaire-39 (“PDQ-39”) Summary Index score, a patient and caregiver reported quality of life measure was recorded at baseline, month three and month six. The average score at baseline was 50 points, which at month three had improved to an average score of 31 points (a reduction of 19 points from baseline). At month 6, the average PDQ-39 Summary Index score was further improved to 18 points (a reduction of 32 points from baseline). These scores demonstrate an approximate 37% improvement from baseline at month three and an approximate 65% improvement from baseline at month six. These reductions in total score at both three and six months appear to indicate a substantial clinical benefit in this quality of life measure.
In addition, a patient-recorded diary was collected again at six months. On average, the patients experienced an improvement from baseline of ON time without dyskinesia of 2.7 hours, a reduction of 2.4 hours in ON time with non-troublesome dyskinesias, a reduction of ON time with troublesome dyskinesias of 1.5 hours, and an increase in OFF time of 0.9 hours.

Pavan Cheruvu, M.D., Chief Executive Officer of Axovant, commented: “We are committed to our mission of developing clinical-stage gene therapies for the treatment of neurological diseases. Based on the encouraging data seen in the Parkinson’s disease and GM2 gangliosidosis programs, the team will focus its efforts on our clinical programs.”
AXO-Lenti-PD is an investigational gene therapy for the treatment of Parkinson’s disease that is designed to deliver three genes (tyrosine hydroxylase, cyclohydrolase 1, and aromatic L-amino acid decarboxylase) via a single lentiviral vector to encode a set of critical enzymes required for dopamine synthesis, with the goal of reducing variability and restoring steady levels of dopamine in the brain. The investigational gene therapy aims to provide patient benefit for years following a single administration.
Axovant, part of the Roivant family of companies, is a clinical-stage gene therapy company focused on developing a pipeline of innovative product candidates for debilitating neurological and neuromuscular diseases. The company’s current pipeline of gene therapy candidates targets GM1 gangliosidosis, GM2 gangliosidosis (including Tay-Sachs disease and Sandhoff disease), and Parkinson’s disease. Axovant is focused on accelerating product candidates into and through clinical trials with a team of experts in gene therapy development and through external partnerships with leading gene therapy organizations.
