Outcome Measures

Primary Outcomes (2)

• Safety assessment

  The frequency of adverse events during the study: adverse events of an immediate type (allergic reactions) that occur within 2 hours after administration of the drug under study and identified both by the researcher and according to information provided to the researcher by the patient's parent; adverse events (local and systemic reactions) that occur within 7 days after administration of the test drug and are identified according to information provided to the researcher by the patient's parent; other adverse events that occur 7 days after administration of the test drug (from 8 to 84 days after administration of the test drug, without taking into account the permissible interval of visits) and noted by the patient's parent in the Self-observation Diary.

  14 weeks

• Efficasy assessment

  The change in the level of spasticity (decrease in score) on the Modified Ashworth Scale (MAS) scale at week 4 compared to the baseline level from 1 to 4 points.

Miotox®(Botulinum toxin type A is a hemagglutinin complex)

EXPERIMENTAL

Children of the younger age group from 2 to 12 years (2 years 0 months 0 days - 11 years 11 months 29 days) Group 1 - 40 children who were injected with the drug Miotox®;

Drug: Miotox (Botulinum toxin type A is a hemagglutinin complex)

Botox (Botulinum toxin type A - hemagglutinin complex - 100 units)

ACTIVE COMPARATOR

Children of the younger age group from 2 to 12 years (2 years 0 months 0 days - 11 years 11 months 29 days) Group 2 - 40 children who were injected with Botox®.

Drug: BOTOX®

Interventions

Miotox (Botulinum toxin type A is a hemagglutinin complex) DRUG

During the study, patients were injected with the investigational drug Miotox® . For the treatment of spasticity and equine varus deformity of the foot in children with cerebral palsy, drugs were injected into two points of each head of the calf muscle (medial and lateral). In case of damage to one limb, the total dose was 4 units / kg of body weight per affected limb. In diplegia, the total dose was 6 units / kg of body weight for both affected limbs. The total total dose should not exceed 200 units. This course of treatment is based on the current instructions for the medical use of Botox®.

• Children and their parents who are able to fulfill the requirements of the Protocol (i.e., fill out a self-observation diary, come to control visits).

You may not qualify if:

• During the study, patients were excluded if any of the following criteria were present:
