Study Description
Brief Summary
The purpose of this study is to assess the safety and tolerability of an oral solution of CDX-6114 when administered as a single dose in healthy volunteers

Phase 1 |
Detailed Description
This is a second Phase 1, double-blind, placebo-controlled study in approximately 24 healthy volunteers who are 18 to 55 years old. Three cohorts are planned each consisting of 8 subjects; the cohorts as planned are 7.5, 15.0 and 22.5 g of CDX-6114 (or matching placebo) in oral solution. Increasing doses of CDX-6114 will be assessed sequentially un til the final dose is evaluated or any of the stopping criteria are reached. Subjects will each receive either a single dose of CDX-6114 or matching placebo, with food, and will then be followed for a total of 22 days (3 weeks).

Outcome Measures
Primary Outcome Measures
- The incidence of treatment-emergent adverse events experienced by the subjects following oral administration of CDX-6114 [Up to 22 days after drug administartion]
Will be measured by assessing the frequency and the nature of the AEs reported
Secondary Outcome Measures
- Pharmacokinetics of CDX-6114 [Up to 24 hours after drug administration]
Assessed by the serum levels of CDX-6114 following oral administration of CDX-6114
- Pharmacodynamics of CDX-6114 [Up to 24 hours after drug administration]
Assessed by the plasma levels of phenylalanine and cinnamic acid following oral administration of CDX-6114
