Study Purpose:
This is a multi-center, open-label study of MN-166 (ibudilast) in subjects with ALS. To be eligible subjects must meet the El Escorial criteria of possible, laboratory-supported probable, probable, or definite criteria for a diagnosis of ALS. Safety, tolerability, blood, neuro-imaging biomarkers, and clinical outcomes will be collected on all subjects. Subjects will receive study drug for 36 weeks.The study will consist of a Screening Phase (up to 6 weeks), an Open-Label Treatment Phase (36 weeks) and a Off-Treatment Follow-up Phase (4 Weeks).
Number of Subjects (Planned):
Approximately 45 subjects are planned to be screened with the goal of enrolling 35 subjects.

Full Study Summary:
This is a multi-center, open-label study of MN-166 (ibudilast) in subjects with ALS. To be eligible subjects must meet the El Escorial criteria of possible, laboratory-supported probable, probable, or definite criteria for a diagnosis of ALS. Safety, tolerability, blood, neuro-imaging biomarkers, and clinical outcomes will be collected on all subjects. Subjects will receive study drug for 36 weeks.
The study will consist of a Screening Phase (up to 6 weeks), an Open-Label Treatment Phase (36 weeks) and a Off-Treatment Follow-up Phase (4 Weeks).
During the Screening Phase, eligible ALS subjects will sign an informed consent form and the following screening assessments will be performed: review of inclusion/exclusion criteria: El Escorial ALS Diagnostic criteria, medical history and demographics, ALS diagnosis history, physical and neurological examination, U. Penn upper motor Neuron Burden (UMNB), pulmonary function tests, vital signs including height and weight, blood for safety labs including TSPO affinity test, ECG and review and documentation of concomitant medications and therapies.
Screening Phase (up to 6 weeks) The Treatment Phase will consist of a Baseline visit and 3 subsequent clinic visits at Weeks 4, 12, 24, and 36. Telephone follow-ups will occur at Weeks 1, 2, 8, 16, 20, 28, and 32.
Open-Label Treatment Phase (36 weeks) At the Baseline visit, subjects will return to the clinic and the following assessments will be performed/administered: review of inclusion and exclusion criteria for continued eligibility, vital signs, blood for safety labs and biomarkers, ECG, ALSFRS-R questionnaire, slow vital capacity (SVC), baseline strength as measured by hand held dynamometry (HHD), and Columbia Suicide Severity Rating Scale (C-SSRS). At this visit, study drug will be dispensed, and adverse events, concomitant medications and therapies will be assessed and documented. At subsequent visits during the Treatment Phase, similar assessments will be performed.
In addition, a [11C]PBR28-PET scan will be performed once between the Screening and Baseline visit, and once between the Week 20 and Week 28 phone calls. The ALSFRS-R, SVC and U Penn Upper Motor Neuron Burden will be repeated on the same day as the PET scans.
The follow-up visit will consist of a telephone call to document adverse events and concomitant therapies

Can participants use Riluzole?
Yes
Inclusion Criteria:1. Subjects must be diagnosed as having possible, probable, probable-laboratory supported, or definite ALS, either sporadic or familial according to modified El Escorial criteria.
