Idiopathic Parkinson´s Disease
Conditions
Brief summary
The aim of this phase Ila trial is to provide evidence on safety, tolerability and symptomatic efficacy of the ROCK-inhibitor Fasudil in patients with early Parkinson's disease (PD). Fasudil has shown neuroprotective and pro-regenerative effects, modulated microglial activity and attenuated alpha-synuclein aggregation in PD models in vitro and in vivo. It has been licensed in Japan since 1995 for the treatment of vasospasms and has a beneficial safety profile arguing for its repurposing. Up to 15 trial centers in Germany will recruit patients. Blinded trial medication will be prepared and shipped by the University Pharmacy Leipzig. Fasudil in two dosages or placebo will be administered orally twice daily to 75 early PD patients for a total of 3 weeks. Safety, tolerability and symptomatic efficacy endpoints will be assessed up to 4 weeks after end of treatment. Its well-known safety profile and the lack of disease-modifying treatments for PD justifies its use in patients with early Parkinson's disease. ROCK-PD is a prerequisite for subsequent long-term clinical trials assessing disease-modification in PD in addition to symptomatic efficacy.

Inclusion criteria
1. Patients with a diagnosis of at least probable PD according to MDS criteria (Postuma et al. MovDis 2015) and 2. Hoehn \& Yahr stage 1 - 3 3. must be non-fluctuating (no wearing-off, no dyskinesia) and stable on symptomatic PD medication for at least 6 weeks 4. age: 30 - 80 years 5. Women of childbearing potential must be non-lactating and surgically sterile or using a highly effective method of birth control and have a negative pregnancy test. Acceptable methods of birth control with a low failure rate (i.e. less than 1% per year) when used consistently and correct are for example implants, injectables, combined oral contraceptives, hormonal intrauterine devices (IUDs), sexual abstinence or vasectomized partner 6. Capable of thoroughly understanding all information given and giving full informed consent according to GCP
Exclusion criteria
1. Atypical, secondary Parkinsonian syndromes, PD mimics, or any other medical condition known to have an association with Parkinsonian syndromes, which might confound or obscure the diagnosis of PD 2. Patients with a history of intracranial bleeding, known intracerebral aneurysms or Moyamoya disease, or positive family history for the above. If only family history positive, MR- or x-ray-based cranial imaging not older than 24 months must confirm absence of bleeding, aneurysms, or Moyamoya 3. Presence of any concomitant life-threatening disease or impairment likely to interfere with functional assessment 4. Patients with known arterial hypotension (resting blood pressure \<90/60 mmHg) or previous hypotensive episodes or requiring treatment for increasing of blood pressure, such as fludrocortisone, midodrine, etilefrine, cafedrine, or theodrenaline 5. Patients with an uncontrollable or unstable arterial hypertensive disease (resting blood pressure \>180 mmHg systolic and/or \>120 mmHg diastolic under current antihypertensive medication) 6. Known pulmonary hypertension and any medication prescribed for treatment of pulmonary hypertension 7. Confirmed hepatic insufficiency or abnormal liver function (stable ASAT and/or ALAT greater than 3 times the upper limit of the normal range) and determined to be non-transient through repeat testing 8. Renal insufficiency with a glomerular filtration rate (GFR) \<60 ml/min/1,73m² (calculated by MDRD equation or byCKD-EPI equation) and determined to be non-transient through repeat testing 9. Major psychiatric disorder, significant cognitive impairment or clinically evident dementia precluding evaluation of symptoms 10. Hypersensitivity to any component of the IMP 11. Liable to be not cooperative or comply with the trial requirements (as assessed by the investigator), or unable to be reached in the case of emergency 12. Pregnant or breast-feeding females or females with childbearing potential, if no adequate contraceptive measures are used 13. Previous participation in another clinical study involving trial medication within the preceding 12 weeks or five terminal half times of the longest to be eliminated trial medications (whichever is longer) or previous participation in this trial
