Trial Outcomes & Findings for Antihypertensive Treatment in Acute Cerebral Hemorrhage (NCT NCT00415610)

NCT ID: NCT00415610

Last Updated: 2017-11-21

Results Overview

Feasibility of treatment was assessed by whether SBP reduction and maintenance within the respective target range was achieved (treatment success) or not (treatment failure), and secondarily by whether a significant difference between treatment arms was achieved. Treatment failure was defined based on the observed hourly hourly minimum SBP remaining greater than the upper limit of the target range for 2 consecutive hours after initiation of nicardipine infusion. Spontaneous decline of SBP below the lower limit of the specific tier was not considered treatment failure as all such declines were asymptomatic.The lower number in the more intensive treatment groups reflects in part the greater challenge of rapidly lowering systolic blood pressure to a more intensive (lower) range, as a higher number of treatment failures as pre-defined by meeting the SBP range goal within 3 hours of symptom onset in this group predictably occurred.

Participant Flow

Patients 18 years and older presenting to site hospital ED and ICU areas within 6 hours of symptom onset for ≤ 60 cc volume intracerebral hemorrhage, with GCS ≥ 8, systolic blood pressure ≥ 170 mmHg and meeting all inclusion/exclusion criteria were enrolled following consent by themselves or a family member/legally authorized representative.

A progressive, three-tiered approach to lowering systolic blood pressure with DSMB review after enrollment in each successive SBP range was completed. Safety was determined at each level before progressing to the next. Subjects meeting criteria and consenting to participate were considered enrolled and have been included in the data analysis.

Timeframe: within the first 72 hours of treatment initiation

Population: All subjects entered in the trial were followed and their data analyzed for safety measures. Not all subjects entered in the trial survived or remained in the trial to assess final outcomes at 1 or 3 months. When safety stopping rules could not have triggered after 18 initial subjects recruitment was adjusted to weight the subsequent tiers.

Neurological status was monitored quantitatively and independently of other adverse events using two scales. The Glasgow Coma Scale (GCS) score measures level of consciousness in eye, motor, and verbal components. At least one point is given in each category. The scale ranges from 3 to 15, with 3 indicating deep unconsciousness and 15 indicating consciousness is not impaired. The National Institutes of Health Stroke Scale (NIHSS) quantifies neurologic deficits in 11 categories. Level of consciousness, horizontal eye movements, visual fields, facial palsy, movement in each limb, sensation, language and speech, and extinction or inattention on one side of the body are tested. Scores range from 0 to 42; 0 indicates normal function and higher scores indicate greater deficit severity.

Serious adverse events were ascertained by site investigators using FDA-defined guidelines, defined as any untoward clinical events having been fatal, life-threatening, resulting in new or prolonged hospitalization, resulting in disability or congenital anomaly, or requiring intervention to prevent permanent impairment or damage. Subjects were followed closely from randomization through 90 days. The initial 72-hour period was chosen as the most meaningful time period for which to examine SAEs likely to be related to the acute safety of the study treatment.

OTHER_PRE_SPECIFIED outcome

Timeframe: From enrollment through 3 months

Population: Serious adverse events were monitored for all patients throughout the 3-month study period; when mortality resulted death was categorized as having occurred prior to or following hospital discharge. The 3-month mortality count includes deaths that occurred earlier. Survival was confirmed at hospital discharge, 1 month, and 3 months.

The tolerability of the study treatment was further ascertained by examination of in-hospital, 1-month, or 3-month mortality in each treatment group. This pilot study was not powered (did not plan to enroll an adequate number of patients) to draw meaningful conclusions about individual adverse event categories, outcome measures, or to make comparisons between the treatment arms beyond the overall feasibility and tolerability of rapidly and significantly lowering SBP following intracerebral hemorrhage. The timing and magnitude of SBP reduction was also compared to the timing of individual safety events to further evaluate possible relationships between the study treatment, adverse events, and any recognizable safety concerns.

Measure
Tier 1
n=18 participants at risk
Dose escalation: Initial range The scientists will investigate the potential consequences of controlling blood pressure with intravenous nicardipine at 170 to 200 mmHg Nicardipine: Intravenous (IV) nicardipine infusion. It is expected that the treatment duration will vary between 18 and 24 hours. * Started at 5mg/h * Titrated by 2.5mg/hour every 15 minutes to bring systolic blood pressure in target range for the applicable Tier. Max dose 15mg/hour \*Once target systolic blood pressure reached, dose decreased by 2.5mg/hour every 15 minutes until systolic blood pressure maintained in the target range or the medication is discontinued. The DSMB will review safety, tolerability, and feasibility before escalation to the next level.
Tier 2
n=20 participants at risk
Dose escalation: The scientists will investigate the potential consequences of controlling blood pressure with intravenous nicardipine at 140 to 170 mmHg Nicardipine: Intravenous (IV) nicardipine infusion. It is expected that the treatment duration will vary between 18 and 24 hours. * Started at 5mg/h * Titrated by 2.5mg/hour every 15 minutes to bring systolic blood pressure in target range for the applicable Tier. Max dose 15mg/hour \*Once target systolic blood pressure reached, dose decreased by 2.5mg/hour every 15 minutes until systolic blood pressure maintained in the target range or the medication is discontinued. The DSMB will review safety, tolerability, and feasibility before escalation to the next level.
Tier 3
n=22 participants at risk
Dose escalation: The scientists will investigate the potential consequences of controlling blood pressure with intravenous nicardipine at 110 to 140 mmHg Nicardipine: Intravenous (IV) nicardipine infusion. It is expected that the treatment duration will vary between 18 and 24 hours. * Started at 5mg/h * Titrated by 2.5mg/hour every 15 minutes to bring systolic blood pressure in target range for the applicable Tier. Max dose 15mg/hour \*Once target systolic blood pressure reached, dose decreased by 2.5mg/hour every 15 minutes until systolic blood pressure maintained in the target range or the medication is discontinued.
