Study Purpose:
Patients with rapidly progressive ALS will be assigned to IC14 intravenously on Day 1-4. This 4-day course will be repeated on Days 8-11. Patients will all undergo MR-PET scans at two time points: before treatment onset and after the last treatment cycle. This scan will measure areas of ALS disease activity and assess response to IC14 treatment. MR-PET scans will be compared to historical controls.Study Status:

Full Study Summary:
This is an open-label, biomarkers-driven study.
Patients with rapidly progressive ALS will be assigned to the following dose regimen of IC14:
• 4 mg/kg intravenously on Day 1, followed by 2 mg/kg daily x 3 days on Days 2-4. This 4-day course will be repeated on Days 8-11.
Patients will be followed for 28 days after the last dose of study drug. Patients will all undergo [11C]-PBR28-MR-PET scans at two time points: before treatment onset and after the last treatment cycle.
Patients will be followed for 28 days after the last dose of study drug for safety.

3. Stable hormonal contraception for at least 3 months prior to study through study completion; or
4. Surgical sterilization (vasectomy) of male partner at least 6 months prior to study.
10. To be considered of non-childbearing potential, females should be surgically sterilized (bilateral tubal ligation, hysterectomy, or bilateral oophorectomy at least 2 months prior to study) or be post-menopausal and at least 3 years since last menses.
