dihydroxyphenylalanine and Bilateral Headache

dihydroxyphenylalanine has been researched along with Bilateral Headache in 4 studies

Dihydroxyphenylalanine: A beta-hydroxylated derivative of phenylalanine. The D-form of dihydroxyphenylalanine has less physiologic activity than the L-form and is commonly used experimentally to determine whether the pharmacological effects of LEVODOPA are stereospecific.
dopa : A hydroxyphenylalanine carrying hydroxy substituents at positions 3 and 4 of the benzene ring.

Trial Outcomes

Change From Baseline in Movement Disorder's Society - Unified Parkinson's Disease Rating Scale (MDS-UPDRS) (Parts I-III Combined Scores)

"To evaluate clinical progression of PD as assessed by the MDS-UPDRS, combined score, Parts I, II, and III.~Part I - non-motor experiences of daily living; Part II - motor experiences of daily living; Part III - motor examination. Parts I and II each contain 13 questions measured on a 5-point scale (0-4). Part III contains 18 objective rater assessments of the motor signs of PD measured on a 5-point scale (0-4).~Total range for combined score (Part I-III) is = 0-176. Generally for MDS-UPDRS scores and sub-scores, the lower the score, the better.~Parts I, II, and III are summed to make the total score." (NCT02202551)
Timeframe: Up to 101 weeks. MDS-UPDRS was performed at the following visits: Screening, Week 8, Week 16, Week 28, Week 40, Week 52, Week 64, Week 76, Week 88, Week 100 (or ET).

Change From Baseline in Movement Disorder's Society - Unified Parkinson's Disease Rating Scale MDS-UPDRS (Part IV - Motor Complications)

"This component (Questions 4.1 - 4.6) includes time spent with dyskinesia, functional impact of dyskinesia, time spent in OFF state, functional impact of fluctuations, complexity of motor fluctuations, painful OFF-state dystonia. Questions 4.1-4.6 are summed to make the Part IV score.~Generally for MDS-UPDRS scores and sub-scores, the lower the score, the better. Total range for Part IV is = 0-24" (NCT02202551)
Timeframe: 100 Weeks. MDS-UPDRS was performed at the following visits: Screening, Week 8, Week 16, Week 28, Week 40, Week 52, Week 64, Week 76, Week 88, Week 100 (or ET).

Number of Participants With Reported AEs and Safety-Related Study Drug Discontinuations

The primary objective of the study was to evaluate the safety and tolerability of ADS-5102 oral capsules, an extended release (ER) formulation of amantadine, administered at a dose of 340 mg once daily at bedtime for the treatment of levodopa-induced dyskinesia (LID) in subjects with Parkinson's disease (PD). (NCT02202551)
Timeframe: Up to 101 weeks
