NCT ID: NCT02525471

Last Updated: 2021-05-28

Results Overview

Safety will be assessed by the occurrence of adverse events over the course of 24 weeks of treatment plus the 4 week off-drug follow-up period (total of 28 weeks). Per the protocol, the first treatment was administered at Baseline (Day 0) and the 24th treatment was administered at Week 23 (Day 161), and a safety phone call performed at Week 28 (Day 196).

Timeframe: 24 Weeks

Population: Eleven (11) subjects participated in the imaging sub-study. Blood biomarkers were collected in a selected subset of subjects per protocol inclusion and exclusion criteria. Samples not collected were due to tech difficulties.

Selected biomarkers of inflammation were measured at Baseline and Week 23 on a sub-set of subjects. Biomarkers included IL-17 plasma levels and FOXP3 mRNA expression in whole blood, a marker of Treg function. Per the protocol, the first treatment was administered on Day 0 (Baseline) and the 24th treatment was administered on Day 161 (Week 23).

PRIMARY outcome

Timeframe: 24 Weeks

Population: A total of nine (9) participants completed both PET scans at Baseline and a follow-up scan after at least 18 weeks of treatment with RNS60 (study drug).

Glial activation was estimated in a subset of participants by magnetic resonance positron emission tomography (MR-PET) using the \[11C\]-PBR28 ligand. The subset excludes individuals homozygous for the T/T allele of the Ala147Thr TSPO polymorphism (rs6971) associated with low affinity for \[11C\]-PBR28. Glial activation was quantified as a mean standardized uptake value (SUV) using PET images acquired 60 to 90 minutes post-injection of approximately 430 MBq \[11C\]-PBR28. FreeSurfer v6.0 (https://surfer.nmr.mgh.harvard.edu) was employed to circumscribe a region of interest (ROI) defined anatomically as the precentral gyrus and the anterior portion of the paracentral lobule, bilaterally. SUV of the ROI was normalized to the SUV of the whole brain and expressed as a SUV ratio (SUVR) to control for inter-individual variability in the global \[11C\]-PBR28 PET signal. Per the protocol, the first treatment was administered on Day 0 (Baseline) and the 24th treatment was administered on Day 161 (

The vital capacity (VC) (percent of predicted normal) was determined using the slow VC method. Vital Capacity is the maximum amount of air a person can expel from the lungs after a maximum inhalation. A subject's VC depends on their age, sex and height. The value is recorded as the Week 23 minus the Baseline of percent of predicted normal.Per the protocol, the first treatment was administered on Day 0 (Baseline) and the 24th treatment was administered on Day 161 (Week 23).

Accurate Test of Limb Isometric Strength (ATLIS) is a non-invasive device that allows measurements of isometric strength in 12 muscle groups of the arms and legs using a standard protocol (elbow and knee flexion and extension, grip, and dorsiflexion). Results are presented as Week 23 minus Baseline of percentages of predicted normal strength based on age, gender, height, and weight using normative data. Per the protocol, the first treatment was administered on Day 0 (Baseline) and the 24th treatment was administered on Day 161 (Week 23).

The ALSFRS-R is a quickly administered (5 minute) ordinal rating scale used to determine a subject's assessment of their capability and independence in 12 functional activities. There are 12 questions, graded by the subject 0-4 (4 is normal). Score of 0 (worst) to 48 (best). Reflects change from Baseline to Week 23 in speech and swallowing, fine motor skills, large motor skills, and breathing. Per the protocol, the first treatment was administered on Day 0 (Baseline) and the 24th treatment was administered on Day 161 (Week 23).
