University Hospital, Basel, Switzerland
Brief Summary

Trial investigates the benefits and harms of Levodopa /Carbidopa 100/25mg compared to placebo (given in addition to standardized rehabilitation based on the principles of motor learning) and whether there is an association with a patient-relevant enhancement of functional recovery in acute stroke patients. Study participants will be randomized 1:1.

Detailed Description

Trial investigates whether Levodopa/Carbidopa compared to placebo given in addition to standardized rehabilitative therapy in patients with acute stroke is associated with

a) patient relevant improvements of physical function b) improvement in patient-self assessed general health aspects, pain, mood, anxiety, fatigue and social participation c) long-term sustainability of a patient-relevant improvement of motor function d) improvement of selective hand and wrist movement e) a higher rate of patients walking independently of the help of another person.

f) less severe impairment g) a higher level of activity of daily living h) improvements of quality of life (i) better cognitive performance (j) no signals of harms (i.e. indications for increased all-cause mortality, recurrent stroke, serious adverse events, and non-serious, pre-specified adverse events possibly related to the IMP)

Estrel-Longterm: optional prolongation of the observational study phase. To investigate the long-term outcomes of our study population the investigator aim to offer an optional prolongation of the observational phase to the participants through regular structured (once yearly) telephone visits.

The telephone visits will be carried out annually for the following 4 years.

Primary Outcome Measures
NameTimeMethod
Fugl-Meyer-Motor Assessment Score (FMMA)Assessed 3 months +/- 14 days after randomization

FMMA is a stroke-specific impairment index designed to assess motor recovery. Scale items are scored on the basis of ability to complete the item using a 3-point ordinal scale (0=cannot perform; 1=performs partially and 2= performs fully). FMMA total scores range from 0 (no movements) to 100 (normal movements) with 66 points for movements of the upper limbs (FMMA-UE) and 34 for those of the lower limbs (FMMA-LE). A difference of 5.25 points for the upper extremity and 6 points for the lower extremity part of the score are described as minimal clinically important difference. For this study, based on these data, 6 points difference are considered a patient-relevant difference between both treatment groups for the primary endpoint.

Secondary Outcome Measures
NameTimeMethod
NIH-Stroke Scale Score (NIHSS)Assessed at Day 0 (Randomization), 5 weeks after randomization, 3 months +/- 14 days after randomization, 6 months +/- 20 days after randomization and 12 months +/- 30 days after randomization

To objectively quantify the impairment caused by a stroke. NIHSS is composed of 11 items, each of which scores a specific ability between a 0 and 4. For this study, an extra item for distal arm paresis was included (score from 0-2). For each item, a score of 0 typically indicates normal function in that specific ability, while a higher score is indicative of some level of impairment. The individual scores from each item are summed in order to calculate a patient's total NIHSS score. The maximum possible score is 42 (+4 for distal arm paresis), with the minimum score being a 0.

Modified Rankin Scale Score (mRS)Assessed at Day 0 (Randomization), 5 weeks after randomization, 3 months +/- 14 days after randomization, 6 months +/- 20 days after randomization and 12/24/36/48/60 months +/- 30 days after randomization

Scale for measuring the degree of disability or dependence in the daily activities of people who have suffered a stroke or other causes of neurological disability. The scale runs from 0-6, running from perfect health without symptoms to death.

0 - No symptoms.

1. - No significant disability. Able to carry out all usual activities, despite some symptoms.

2. - Slight disability. Able to look after own affairs without assistance, but unable to carry out all previous activities.

3. - Moderate disability. Requires some help, but able to walk unassisted.

4. - Moderately severe disability. Unable to attend to own bodily needs without assistance, and unable to walk unassisted.

5. - Severe disability. Requires constant nursing care and attention, bedridden, incontinent.

6. - Dead.
