CC100: Phase 1 Multiple-Dose Safety and Tolerability in Subjects With ALS

Study Overview
=================
Brief Summary
-----------------
Approximately 21 subjects with amyotrophic lateral sclerosis (ALS) will be randomized (6 to 1) to receive by mouth seven morning doses of CC100 or placebo for 7 days. Subjects are required to stay in the Clinic for approximately 9 hours following the first and last dose. Subjects will also have a mid-week clinic visit and will be contacted by phone within 3 to 5 days after the last dose. Funding Source - FDA OOPD

Detailed Description
-----------------
Primary objective: to assess the safety and tolerability of multiple doses of orally administered CC100 in subjects with amyotrophic lateral sclerosis (ALS). Secondary objectives: to determine pharmacokinetics and pharmacodynamics of CC100 in plasma after single and after multiple doses; and to determine short-term effects of CC100 on potential blood-cell ALS biomarkers. Study Design: Phase 1 double-blind, randomized, placebo-controlled multiple-dose of three CC100-dose cohorts. Approximately 18 subjects will receive CC100. Approximately 3 subjects will be randomized to placebo (across 3 cohorts). Periodic Assessment Committee safety reviews. Note: Participation will not exclude subjects from future CC100 studies Criteria for Evaluation: Safety Endpoints: Adverse events, blood chemistry, hematology, urinalysis, vital signs, 12-lead ECGs. Pharmacokinetic (PK)/Pharmacodynamic (PD): Plasma for CC100 concentrations (PK). Blood collected at baseline and after each subject's last dose will be assayed for potential biomarker(s). Stored specimens will be de-identified or combined for validating diagnostic tools/assays related to ALS. Statistical Methods: A minimum of 6 subjects per CC100 dose group and 3 placebo-dosed subjects (total across cohorts) are considered sufficient to evaluate initial safety and tolerability for the cohorts. Pharmacokinetic parameter estimates will be calculated by standard noncompartmental methods of analysis. Absolute bioavailability of administration will be estimated based on the total area under the time- concentration curve (AUC0-∞).

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Safety and Tolerability: Adverse events, safety labs, vital signs, and ECGs | Safety and tolerability assessed by group/dose measured by number of unsolicited adverse events (MedDRA), and changes in blood chemistry, hematology, urinalysis, vital signs, and 12-lead ECGs from baseline (prior to dosing). | From start of first dose to a minimum of 3 days after last dose | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Pharmacokinetics (PK)--Peak plasma concentration (Cmax) | Cmax after first (single) and last (multiple) CC100 doses | 0.5, 1, 2, 4, and 8 hours after first and last dose | 
| Pharmacokinetics (PK)--Area under the plasma concentration versus time curve (AUC) | AUC after first (single) and last (multiple) CC100 doses | 0.5, 1, 2, 4, and 8 hours after first and last dose | 
| Pharmacokinetics (PK)--Half life (T 1/2) | Estimated half-life after first (single) and last (multiple) CC100 doses | 0.5, 1, 2, 4, and 8 hours after first and last dose | 
| Pharmacodynamics (PD)--Monocyte chemotactic protein 1 (MCP-1) | Short-term effects of CC100 on potential ALS inflammation biomarker MCP-1 | Pretreatment and 8 hours post last dose |
