Clinical Trial Summary

The experimental design is an open-label two-week trial of tolcapone to evaluate which clinical domains are affected by tolcapone treatment and to identify "responders" to tolcapone treatment in the two subject groups (BI and NCD)


Clinical Trial Description

Each patient will receive a two-week specified dosing amount of tolcapone (100mg TID on Day 1; 200mg TID on Days 2-14). The patient will be instructed to take the study drug three times daily. Tolcapone will be tapered after Day 14 to avoid potential withdrawal reactions.

Clinical Instruments for patients:

- Question banks from large patient-reported outcome measure initiatives will be used and administered and used by computerized-adaptive tests (CATs). These include the TBI-QoL for patients with TBI and question banks from the patient-reported outcome measure information systems (PROMIS) and neurology quality of life measurement initiative (Neuro-QoL). Patients will answer questions related to their mobility, fatigue, pain interference, positive affect and well-being, depression, anxiety, anger and irritability, and emotional and behavioral dyscontrol.
