Brief Summary:
The objective of this randomized, double-blinded, placebo-controlled Phase 1 investigation is to evaluate the safety and potential clinical effect of AAV2-GDNF delivered to the putamen in subjects with either a possible or probable diagnosis of Multiple System Atrophy.

Condition or disease Intervention/treatment Phase
Multiple System Atrophy Biological: AAV2-GDNF gene therapy Procedure: Sham (Placebo) Surgery Phase 1

Layout table for study information
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
Estimated Study Start Date : April 2023
Estimated Primary Completion Date : March 2024
Estimated Study Completion Date : March 2026

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

Primary Outcome Measures :
  1. 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.

Secondary Outcome Measures :
  1. 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.

  2. 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

  3. 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.
