Trial Outcomes & Findings for Clinical Study of TA-650 in Patients With Behcet's Disease (BD) With Special Lesions (NCT NCT01532570)

NCT ID: NCT01532570

Last Updated: 2016-12-16

Results Overview

We defined the patient who met the following criteria as the complete responders. The criteria of complete responders are that clinical symptoms associated with each BD have disappeared and morphological characteristics (ex. ulcers area, Computed tomography (CT) or Positron emission tomography/Computed tomography (PET/CT) findings etc) at the lesion site and inflammatory markers (ex. cerebrospinal fluid and serum inflammatory markers) are improved compared to Week 0.

The VAS evaluation measured using the "General VAS evaluation From" and the range is from 0 to 100 mm. The best condition per one week before evaluation visit for the clinical symptoms associated with each BD is defined as "0" and the worst condition is defined as "100". The time of final evaluation : Final time point for the 5 mg/kg patients, final time point during administration of 5 mg/kg for the 10 mg/kg patients, final time point during administration of 5 mg/kg for patients who discontinued the study.
