Condition or disease | Intervention/treatment | Phase |
---|---|---|
Multiple System Atrophy | Biological: AAV2-GDNF gene therapy Procedure: Sham (Placebo) Surgery | Phase 1 |
Study Type : | Interventional (Clinical Trial) |
Estimated Enrollment : | 9 participants |
Allocation: | Randomized |
Intervention Model: | Parallel Assignment |
Intervention Model Description: | Up to 9 study participants meeting eligibility criteria will be randomized in a 2:1 fashion to receive either the investigational medicinal product or sham surgery in this Phase 1 trial. |
Masking: | Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor) |
Primary Purpose: | Treatment |
Official Title: | Randomized, Double-Blind, Placebo-controlled Safety Study of Glial Cell Line-Derived Neurotrophic Factor Gene Transfer (AAV2-GDNF) in Multiple System Atrophy |
Actual Study Start Date : | October 3, 2023 |
Estimated Primary Completion Date : | December 2025 |
Estimated Study Completion Date : | December 2028 |

Arm | Intervention/treatment |
---|---|
Experimental: Active Treatment |
Biological: AAV2-GDNF gene therapy
Bilateral image-guided infusion of AAV2-GDNF into putamen, single dose |
Sham Comparator: Placebo Surgery |
Procedure: Sham (Placebo) Surgery
Bilateral partial burr/twist holes without dural penetration |
- The incidence of Treatment-Emergent Adverse Events (TEAE) and Serious Adverse Events (SAE) assessed clinically by physical and neurological examinations [ Time Frame: 3 years ]Number of TEAE and SAE's reported post-treatment.
- MSA symptoms/signs as assessed by the Unified Multiple System Atrophy Rating Scale (UMSARS) [ Time Frame: 12 months ]Change from baseline in the Unified Multiple System Atrophy Rating Scale (UMSARS) and compared to placebo. UMSARS total scores range from 0-104 points with higher scores indicating greater severity of impairment.
- Change in striatal dopamine transporter binding as measured by [123-I] Ioflupane [ Time Frame: 12 months ]Percent and absolute change in ratio of specific to non-specific binding of 123I FP-CIT to DaT from baseline and compared to placebo by Single Photon Emission Computed Tomography (SPECT) dopamine transporter (DaT) imaging
- Change in the quality of life as measured by Multiple System Atrophy Quality of Life (MSA-QoL) [ Time Frame: 12 months ]Change from baseline and compared to placebo in the Multiple System Atrophy Quality of Life (MSA-QoL) scale. MSA-QoL is a self-reported questionnaire that measures MSA impact in day to day activities. Scale consists of 40 items with a five response option format (0 - no problem to 4 extreme problem) and a "not applicable" response option.
