Intervention model description
Participants will receive NIDO-361, 100 mg for at least 2 months and 200 mg for the remainder of the study or placebo administered orally once daily for 12 months.
Eligibility
Inclusion criteria
* Ambulatory male * Documented SBMA diagnosis confirmed by DNA genetic testing * Able to complete six-minute walk test (6MWT)
Exclusion criteria
* Clinically significant cardiovascular, endocrine, hepatic, renal, pulmonary, gastrointestinal, neurologic, immunologic, malignant, metabolic, psychiatric, or other condition that, in the opinion of the Investigator, precludes the participant's safe participation in the study or would interfere with the study assessments * Inability to undergo MRI (mild sedation may be allowed)
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Analysis of Thigh and Total Lean Muscle Volume (LMV) [A+B+C] | Baseline, Day 180, Days 360-374 (Last Visit) | Analysis of thigh included adductors, hamstrings, and quadriceps and total (whole-body) included muscles in the rotator cuff, arm, torso, and leg muscle regions (38 muscles in total). Muscles were categorized according to their fat content as follows: A-muscles were defined as muscle fat fraction (MFF) \< 50% and muscle fat infiltration (MFI) \< 10%. A-muscles have a low or slightly elevated fat content to a level that can be present in individuals without a neuromuscular disease. B-muscles were defined as MFF \< 50% and MFI ≥ 10%. B-muscles have a muscle fat content at a level where disease involvement is likely. C-muscles were defined as MFF ≥ 50%. C-muscles have a muscle fat content where more than 50% of the muscle tissue has been replaced by fat and most of the functional capacity is likely lost. |

Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change From Baseline to Day 180 and Day 360 in Modified-SBMAFRS (m-SBMAFRS) | Baseline, Day 180, Day 360 | The modified Spinal and Bulbar Muscular Atrophy Functional Rating Scale (m-SBMAFRS) is calculated as the sum of the items for the truncal and lower-limb domains from the SBMAFRS, which is a validated functional rating scale developed from the Amyotrophic Lateral Sclerosis Functional Rating Scale. Each item has five responses options scoring 0 (worst) to 4 (normal). A higher score indicates better functioning. Total range is 0 (worst) to 30 (normal). |
| Change From Baseline to Day 180 and Day 360 in Two-Minute Walk Test (2MWT) | Baseline, Day 180, Day 360 | 2-minute walk test (2MWT) measures the distance traveled (meters) in 2 minutes. |
| Change From Baseline to Day 180 and Day 360 in 6-Minute Walk Test (6MWT) | Baseline, Day 180, Day 360 | 6-minute walk test (6MWT) measures the distance traveled (meters) in 6 minutes. |
| Change From Baseline to Day 180 and Day 360 in Timed Up and Go (TUG) Test | Baseline, Day 180, Day 360 | The Timed Up and Go Test (TUG) is used to assess mobility and to provide an estimate on balance and risk of falling. Patients are asked to rise from a chair, walk 3 meters, turn around, return to the chair, and sit. The time that it takes to complete the task is recorded. Assistive devices, orthoses, and ankle braces are allowed. |
| Change From Baseline to Treatment (Days 331 to 360) in Actigraphy-Derived Measurement: Non-Sedentary Behavior | Baseline, Treatment (Days 331 to 360) | The Actigraph device is a non-invasive research-grade accelerometer based wearable device that was used to objectively measure free-living physical activity. The data from these devices was used to assess and detect changes in physical activity intensity, upper arm movements, and walking patterns. |
| Change From Baseline to Treatment (Days 331 to 360) in Actigraphy-Derived Measurement: 95th Percentile of 6-Minute Physical Activity Windows | Baseline, Treatment (Days 331 to 360) | The Actigraph device is a non-invasive research-grade accelerometer based wearable device that was used to objectively measure free-living physical activity. The data from these devices was used to assess and detect changes in physical activity intensity, upper arm movements, and walking patterns. |
| Change From Baseline to Treatment (Days 331 to 360) in Acitgraphy-Derived Measurement: Maximum Walking Bout Duration | Baseline, Treatment (Days 331 to 360) | The Actigraph device is a non-invasive research-grade accelerometer based wearable device that was used to objectively measure free-living physical activity. The data from these devices was used to assess and detect changes in physical activity intensity, upper arm movements, and walking patterns. |
| Change From Baseline to Treatment (Days 331 to 360) in Actigraphy-Derived Measurement: Peak 95th Percentile Cadence | Baseline, Treatment (Days 331 to 360) | The Actigraph device is a non-invasive research-grade accelerometer based wearable device that was used to objectively measure free-living physical activity. The data from these devices was used to assess and detect changes in physical activity intensity, upper arm movements, and walking patterns. |
| Change From Baseline to Treatment (Days 331 to 360) in Actigraphy Derived Measurement: Average Breathing Rate | Baseline, Treatment (Days 331 to 360) | The Actigraph device is a non-invasive research-grade accelerometer based wearable device that was used to objectively measure free-living physical activity. The data from these devices was used to assess and detect changes in physical activity intensity, upper arm movements, and walking patterns. |
| Change From Baseline to Day 180 and Day 360 in Grip Strength as Measured by Handheld Dynamometer (HHD) | Baseline, Day 180, Day 360 | Grip strength (lbs) is averaged across three trials for the right and left hands separately using a handheld dynamometer (HHD). |
