APEX-STROKE CALM-ICH Domain (CALM-ICH)

24. august 2026 opdateret af: Fudan University

Chinese Angong Niuhuang for Acute Medical Management of Intracerebral Hemorrhage (CALM-ICH) Domain of the APEX-STROKE Adaptive Platform Trial

In this domain of APEX-STROKE, participants with acute intracerebral hemorrhage (ICH) who meet the eligibility criteria for this domain will be randomized in a 1:1 ratio to receive either Angong Niuhuang pills (ANP) or matching placebo, both in addition to guideline-based standard care. The matching placebo is the control condition and is not counted as a domain intervention.

• Intervention: Angong Niuhuang pills (ANP) in addition to guideline-based standard care.

ANP should be initiated as soon as possible after randomization in the ambulance or emergency department setting, with subsequent treatment continued for a total of 14 days according to the domain-specific intervention schedule.

• Control condition: matching placebo in addition to guideline-based standard care.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: Early Angong Niuhuang Pill (ANP) treatment
Participants in this arm receive early treatment with ANP Within 6 hours of onset.
Medicin: Angong Niuhuang Pills (ANP)
Angong Niuhuang pills (ANP), a Traditional Chinese Medicine formulation supplied as 3 g pills, administered in addition to guideline-based standard care. Awake participants receive one pill orally as soon as possible after randomization. Unconscious participants receive a suspension prepared by removing the pill shell and grinding it with 15 mL room-temperature normal saline (used within 1 hour of preparation): in the ambulance setting, administered onto the tongue in 2-2.5 mL increments every 10 minutes, with the remaining dose given via nasogastric tube after hospital admission; in the emergency department, administered directly via nasogastric tube. After the initial dose, treatment continues as one pill twice daily during week 1 and one pill once daily during week 2, for a total treatment duration of 14 days.
Placebo komparator: Placebo
Participants in this arm will not receive ANP and will receive a matching placebo.
Medicin: Placebo
Matching placebo, identical to Angong Niuhuang pills (ANP) in appearance, smell, taste, dosing schedule, and treatment duration (14 days total). Contains inactive excipients only and is indistinguishable from active treatment to participants, treating teams, outcome assessors, and trial personnel.

Foranstaltningsbeskrivelse
Tidsramme
modified Rankin scale (mRS) scores
Tidsramme: 180 days
The modified Rankin Scale (mRS) is a 7-point ordinal scale assessing global disability and functional dependence after stroke, ranging from 0 (no symptoms) to 6 (death). Intermediate scores indicate increasing severity: 1, no significant disability; 2, slight disability; 3, moderate disability; 4, moderately severe disability; 5, severe disability. The primary analysis will use the ordinal distribution of scores across all 7 levels; lower scores indicate better functional outcome.

Foranstaltningsbeskrivelse
Tidsramme
NIHSS score
Tidsramme: 24 hours and 7 day
The National Institutes of Health Stroke Scale (NIHSS) ranges from 0 (no neurological deficit) to 42 (most severe deficit), assessing consciousness, gaze, visual fields, motor and sensory function, language, and neglect. Higher scores indicate more severe neurological impairment.
24 hours and 7 day
Mortality
Tidsramme: 180 days
All-cause mortality will be reported as the number and proportion of participants who died from any cause by 180 days after randomization.
180 days
Favorable functional outcome (mRS 0-2 and mRS 0-3)
Tidsramme: 180 days
Favorable functional outcome is defined using the modified Rankin Scale (mRS), which ranges from 0 (no symptoms) to 6 (death). Two thresholds will be reported: participants achieving mRS 0-2 (no symptoms to slight disability, independent living) and participants achieving mRS 0-3 (no symptoms to moderate disability, ambulatory without assistance).
180 days
Health-Related quality of Life assessed by EQ-5D
Tidsramme: 180 days
The EQ-5D assesses health-related quality of life across 5 dimensions (mobility, self-care, usual activities, pain/discomfort, anxiety/depression), each scored on a severity scale, combined into a weighted index value, with an accompanying EQ visual analogue scale (EQ-VAS) rated from 0 (worst imaginable health) to 100 (best imaginable health). Higher scores indicate better health status.
180 days
Hematoma volume
Tidsramme: 24 hours
Hematoma volume will be measured on brain CT/MRI in mL using semi-automated volumetric software.
24 hours
Hematoma Expansion at 24 Hours
Tidsramme: 24 hours
Hematoma expansion is defined as an absolute increase of ≥6 mL or a relative increase of ≥33% in hematoma volume between baseline and the 24-hour scan.

Tidsramme
Incidence of Serious Adverse Events
Tidsramme: From randomization through 180 days after randomization
Incidence of serious adverse events (SAEs) occurring during the safety follow-up period. An SAE is defined as an adverse event resulting in death, a life-threatening event, inpatient hospitalization or prolongation of existing hospitalization, persistent or significant disability or incapacity, congenital anomaly or birth defect, or an important medical event that, based on appropriate medical judgment, may jeopardize the participant or require medical or surgical intervention to prevent one of these outcomes.
From randomization through 180 days after randomization
Incidence of Adverse Events of Special Interest
Tidsramme: From randomization through 180 days after randomization
Incidence of adverse events of special interest (AESIs) during the safety follow-up period. AESIs include whole-blood mercury or arsenic concentrations ≥2 times the upper limit of normal (ULN), liver function abnormalities defined as alanine aminotransferase or aspartate aminotransferase >3 times the ULN, and renal function abnormalities defined as serum creatinine ≥2 mg/dL.
From randomization through 180 days after randomization
