|
E.4 | Principal exclusion criteria |
-spasticity of any other origin than stroke -previous treatment with Botulinum Toxin of any serotype and for any body region within the 4 months prior to Screening (Visit 1, Day -7) -planned concomitant treatment with Botulinum Toxin of any serotype and for any body region -previous or planned treatment with phenol- or alcohol-injection in the target limb -previous surgical treatment of spasticity in the target muscle(s) -fixed contracture, defined as severe restriction of the range of joint movement on passive stretch -severe atrophy of the target limb muscles
-bilateral upper limb paresis/paralysis --surgical treatment in the target limb for any indication within the 8 weeks prior to Screening (Visit 1, Day-7) -planned surgery in the target limb -planned elective surgery under general anesthesia during the Main Period -hypersensitivity to human serum albumin, sucrose, or Botulinum Toxin type A -change in antispastic medication with centrally acting muscle relaxants (including benzodiazepines) within the 2 weeks prior to Screening (Visit 1, Day -7) and /or antispastic medication with centrally acting muscle relaxants that is intended to be changed during the Main Period. -antispastic medication with peripheral muscle relaxants (including dantrolene) within the 2 weeks prior to Screening (Visit 1, Day -7) -change in antidepressant medication within the 4 weeks prior to Screening (Visit 1, Day -7) and/or antidepressant medication that is intended to be changed during the Main Period -change in physical or occupational therapy regimens (including splinting) within the 2 weeks prior to Screening (Visit 1, Day -7) and/or physical or occupational therapy that is intended to be changed during the Main Period. -treatment with intrathecal baclofen within 2 weeks prior to Screening (Visit 1, Day -7) -other non-authorized concomitant treatments -concomitant rheumatic disease in the target limb, which in the opinion of the Investigator would affect the therapeutic outcome of treatment with Botulinum Toxin -other muscle hypertonia (e.g rigidity) -current alcoholism or other drug abuse/dependence -diagnosis of myasthenia gravis, Lambert-Eaton-Syndrome, amyotrophic lateral sclerosis, or any other significant neuromuscular disease which might interfere with the study -severe or uncontrolled systemic disease (e.g. cardiac, renal, pulmonary, hepatic, or gastrointestinal), current malignancy or anamnestic HIV infection -clinically relevant pathological findings in laboratory parameters, indicating active disease of vital organs -anticoagulation therapy which requires an International Normalized Ratio [INR] value of greater than 2.5 or Quick Value of less than 30% -INR value of greater than 2.5 on injection day -infection in the area of the planned injection points -nursing mothers -women of childbearing potential without reliable means of contraception (reliable contraception is hormonal contraception or barrier contraception combined with intrauterine contraceptive device) and women planning pregnancy during the course of the trial -in the judgement of the Investigator there is severe impairment of cognition that in the opinion of the Investigator does not enable the patient to fully understand the informed consent and participate in the trial -in the judgement of the Investigator there is severe impairment of communication (e.g. patients with significant aphasia) that in the opinion of the Investigator precludes the patient participating in the trial -participation in a clinical study within the 12 weeks prior to Screening (Visit 1, day -7) -previous participation in this clinical study -in the opinion of the Investigator the patient is unlikely to complete all study visits (Main Period and OLEX Period) -other contraindications which in the Investigator's opinion preclude participation in the study |
