Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A prospective, randomised, double-blind, placebo-controlled, multicentre trial was designed to compare the the incidence of hematoma progression requiring operation or hematoma recurrence requiring re-operation and improves clinical outcomes at 24 weeks in patients with CSDH of treatment in the HXLS and placebo groups.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The CHARM trial is a prospective, randomized, double-blinded, placebo-controlled, multicenter clinical study. The trial aims to investigate the efficacy of the Chinese herbal formula HXLS as an addition to a primary conservative treatment of CSDH in an effort to prevent surgery. The investigators hypothesize that, compared with placebo, the Chinese herbal formula HXLS reduce incidence of hematoma progression requiring operation or hematoma recurrence requiring re-operation and improves clinical outcomes at 24 weeks in patients with CSDH. Consequently, the defined null hypothesis will be that there is no difference between the groups. In total, 160 patients will be randomly assigned to the HXLS group and the placebo group at a 1:1 ratio.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

HXLS group

The HXLS granules are produced from four Chinese herbal pieces: Yi Mu Cao (Leonurus heterophyllus, 15.0g), Zhi Shui Zhi (Hirudo, 1.5g), Tao Ren (Semen persicae, 6.0g), and Hong Hua (Carthamus tinctorius L, 6.0g).

Group Type EXPERIMENTAL

Chinese Herbal formula HuoXue LiShui

Intervention Type DRUG

The intervention consists of the oral administration of granule with either HXLS or a placebo substance, one bag (28.5 g) twice daily after meals for a period of 8 weeks. The granules are produced from four Chinese herbal pieces: Yi Mu Cao (Leonuri Herbal, 15.0g), Zhi Shui Zhi (Hirudo, 1.5g), Tao Ren (Semen persicae, 6.0g), and Hong Hua (Carthami Flos, 6.0g).

placebo group

The placebo will be consistent with the HXLS oral granules in appearance, taste, and weight, to the greatest extent possible. It included Hu Jing (28.0g)

Group Type PLACEBO_COMPARATOR

Chinese Herbal formula Placebo

Intervention Type DRUG

The placebo will be consistent with the HXLS oral granules in appearance, taste, and weight, to the greatest extent possible. In terms of outer packing, the HXLS and placebo granules will be exactly the same. It included Hu Jing (28.5g)
