| Primary | Change From Baseline in I-V Interwave Latency on Brainstem Auditory Evoked Potentials (BAEP) at a Stimulus Intensity of 80 Decibels (dB) From the Right Side at Month 9 | Baseline, Month 9 (Baseline was defined as the last non-missing measurement obtained before the first dose in the placebo-controlled phase) | BAEP interwave I-V latency (in milliseconds) was the primary endpoint for this study. High-intensity stimulation (80dB) was used. Participants had BAEP evaluations performed at the same evaluation center, by the same audiology professional using the same equipment, during the study. Audiology and BAEP evaluations were done on the same day, with audiology assessment first. If they could not be done on the same day, assessments had to be within 7 days of each other. A central reader was used for BAEP to confirm that locally read BAEP waves were labelled appropriately and at their peak so that latency were accurate. Central reading also ensured consistency in BAEP interpretation. |

| Secondary | Change From Baseline in Percentage of Intraepidermal Nerve Fiber (IENF) With Axonal Swelling in Skin Punch Biopsies at Month 9 | Baseline, Month 9 (Month 6 for the 2 participants who entered the Active Therapy Extension Phase at Month 6). Baseline was defined as the last non-missing measurement obtained before the first dose in the placebo-controlled phase. | The endpoint "axonal dystrophy" referred to the percentage of IENF with axonal swellings. Axonal swellings were evaluated in peripheral skin punch biopsies from the distal part of lower extremities. Axonal swellings were counted by axon. Any IENF with single or multiple swellings was counted as a single event, ie, a single axon with axonal swellings. For each participant, data were reported as the percentage of IENF with any number of swellings. IENF was assessed at Day 1 and Month 9. Participants who had entered the Active Therapy Extension Phase at Month 6 had a skin punch biopsy taken at Month 6 for IENF assessments instead of at Month 9. The skin biopsy was collected before the start of Active Therapy Extension Phase. |

| Secondary | Change From Baseline in Intraepidermal Nerve Fiber Density (IENFD) in Skin Punch Biopsies at Month 9 | Baseline, Month 9 (Month 6 for the 2 participants who entered the Active Therapy Extension Phase at Month 6). Baseline was defined as the last non-missing measurement obtained before the first dose in the placebo-controlled phase. | IENFD was evaluated in peripheral skin punch biopsies from the distal part of lower extremities. IENFD was measured by counting the number of fibers and fiber branches that independently crossed the dermal-epidermal barrier (basement membrane). Secondary branching was excluded from quantification and fragments were not counted. The length of the histology section was measured (mm) and the linear epidermal nerve fiber density was reported as number of intraepidermal nerve fibers/mm. |

| Secondary | Number of Participants With Treatment-Emergent Adverse Events (TEAEs) and Treatment-Emergent Serious Adverse Events (TESAEs) | Approximately 16 months | An adverse event (AE) was any untoward medical occurrence in a participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. Seriousness of an AE was assessed under the criteria of serious adverse event (SAE). An SAE was defined as any untoward medical occurrence that, at any dose: resulted in death; was life-threatening; required inpatient hospitalization or prolongation of existing hospitalization; resulted in persistent disability/incapacity; was a congenital anomaly/birth defect, etc. Treatment-emergent events were with onset date occurring during the on-treatment period. Relatedness to study treatment was determined by the investigator. |
| Secondary | Number of Participants Who Discontinued From Study Due to Adverse Event (AEs) | Approximately 16 months | An AE was any untoward medical occurrence in a participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. Participants who had an AE record that indicated that the AE caused the participant to be discontinued from the study. Relatedness to study treatment was determined by the investigator. |
