DMC concluded that the results of 382 included patients were clear.

Primary objectives of the study are to investigate whether adjuvant treatment in the form of Tranexamic acid (Cyklokapron) and Tocilizumab (RoAcmera) to surgery in patients with chronic subdural hematomaina can:

1. effectively decrease the rate of lesion recurrence requiring re-operation,
2. effectively shorten the time of lesion resolution.

Secondary objectives of the study are:1) assess the postoperative functional outcome and quality of life of participants, 2) assess the postoperative mortality of participants, 3) assess the treatment safety data, 4) assess the cure rate of participants.

Primary endpoints in the study are: 1) determine postoperative recurrence requiring reoperation using clinical examination and CT imaging, 2) determine the time period necessary to complete healing using clinical examination and CT imaging.

Secondary endpoints in the study are: 1) to determine the functional outcome and quality of life of the participants using questionnaires, 2) to determine the mortality of the participants related to chronic subdural hematoma, 3) to determine the treatments complications and adverse events of the participants, 4) to determine the curation using clinical examination and CT imaging.

Inclusion Criteria:

• patients with informed consent, without presenting of any known contraindication for the use of Tranexamic acid and Tocilizumab.

Exclusion Criteria:

• patients or relatives who refused to consent, presenting of any known contraindication for the use of Tranexamic acid and Tocilizumab.
