Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Therapeutic management of gait disorders in very advanced Parkinson's disease (PD) patients can sometimes be disappointing, since dopaminergic drug treatments and subthalamic nucleus (STN) stimulation are more effective for limb-related Parkinsonian signs than for gait disorders. Gait disorders could be also partly related to noradrenergic system impairment, pharmacological modulation of both dopamine and noradrenaline pathways could potentially improve the symptomatology. The investigators have demonstrated using an open label study on 17 advanced PD patients that chronic, high doses of methylphenidate (MPD) improved gait, freezing of gait, motor symptoms and attention in the absence of L-Dopa and increased the intensity of response of these symptoms to L-Dopa (Devos et al., 2007). The investigators aimed to confirm their results using a randomized, double-blind, placebo-controlled, parallel-group, multicentric trial. The investigators will assess the clinical value of chronic, high doses (1 mg/kg/day) of MPD vs placebo in 88 non demented PD patients suffering from severe gait disorders with freezing despite their use of optimal dopaminergic doses and eventually STN stimulation parameters. Efficacy will be assessed directly and on video in the absence of L-Dopa and again after acute administration of the drug, both before and after a 3-month course of MPD, using Stand Walk Sit test (primary criteria), the "Freezing Of Gait trajectory", RGSE scale, the UPDRS scores, the dyskinesia rating scale, Achiron scales and using auto-questionnaires of Giladi, ABC scale and PDQ 39. Attention will be assessed using reactions times. Drowsiness will be assessed using Epworth and Parkinson's disease Sleep Scales. Apathy and depression will be monitored with Lille Apathy Rating Scale, MADRS, BPRS, MINI and psychiatric interview. Cardiologic and general tolerance will be also monitored. This study could lead to propose methylphenidate with a good efficacy/ risk balance in advanced PD patients suffering from severe gait disorders with freezing of gait, drowsiness and attention deficit.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Overall study duration: 2 years. Planned inclusion period: 12 months. Study duration for individual patients: 4 months and 2 weeks(2 weeks between screening and randomization, 3 months of double-blind treatment and then a 4-week wash-out period).

Primary objective (V1 and V4):

To assess efficacy of methylphenidate treatment on severe gait disorders including freezing assessed by the Stand Walk Sit Test in patients with advanced Parkinson's disease without dementia or depression and under subthalamic stimulation

Additional Efficacy Endpoints (V1 and V4):

* Gait and motor symptoms: the "Freezing Of Gait trajectory", RGSE scale, the UPDRS scores (partI, II, III, IV), the dyskinesia rating scale
* auto-questionnaires of Giladi, ABC scale and PDQ 39
* Attention: simple and complex reactions times
* Drowsiness: Epworth and Parkinson's disease Sleep Scales
* Apathy Lille Apathy Rating Scale
* Depression and other psychiatric disorders: MADRS, BPRS, MINI and psychiatric interview

Safety and Tolerability Endpoints (V1, V2, V3 and V4):

Tolerability Number of subjects (%) who discontinue the study Number of subjects (%) who discontinue the study due to AEs Safety Measures AE incidence Safety laboratory values Vital signs Blood pressure monitoring ECG Physical and neurological examination

Study Design:

Multicentric study: 12-week double blind, placebo-controlled phase. After being found eligible to participate in the study, subjects will be allocated in a 1:1 ratio into one of the following two treatment groups based on a randomization scheme with blocks stratified:

one methylphenidate

* 1st week: 1/2cp 3 times a day (morning, at noon and at 16h)
* 2nd week: 1cp 3 times a day
* 3rd week: 1cp + 1/2cp 3 times a day
* 4th week: depending on the weight: 2 to 3 cp 3 times a day (1 mg/kg/day)

During the 2 following month: 2 to 3 cp 3 times a day (1 mg/kg/day) one placebo during 3 months same as methylphenidate

Schedule: 10 visits Six short consultations: screening (V0), safety visits every 15 days (V2, V3, V4, V5, V6) and two last consultation for the decrease titration (V8, V9) Two long visits during an hospitalization of two days: randomization (V1, 15 days after V0) and visit of termination (V7, 3 months after randomization)

Patients 76 subjects with Parkinson's disease duration of more than 5 years, without dementia (Mattis Dementia Rating Scale ≥ 130, MMSE ≥ 27 and DSM IV), without major depression (MADRS \< 18) who have severe gait disorders including freezing of gait (defined by an answer 2 or 3 at the 3rd question of the autoquestionnaire of Giladi: Do your gait disorders impede your daily living activities and your independence: answer: yes, moderately or severely. But the patient requires no physical assistance to walk) despite an optimal dopaminergic treatment and optimal and if present stable subthalamic stimulation parameters. No additional therapy will be permitted during the study.
