Brief summary

The purpose of this trial is to evaluate the safety and effectiveness of lowering blood pressure using nicardipine in persons with acute hypertension associated with intracerebral hemorrhage.

Detailed description

An estimated 37,000 to 52,400 people in the United States have intracerebral hemorrhage (ICH) every year. ICH--a form of stroke that has poor outcome and is difficult to treat--is associated with the highest mortality rate of all strokes. Hematoma expansion has been identified as the most common cause of neurological deterioration in persons with ICH. Early evidence suggests that acute hypertension (HTN)-or elevated blood pressure-may make some individuals more susceptible to hematoma expansion. Treating HTN acutely may prevent hematoma expansion, however, the effect of aggressive HTN treatment has not been determined. The purpose of this trial is to evaluate the treatment feasibility and safety of lowering blood pressure using nicardipine--an antihypertensive medication--in persons who have acute HTN associated with ICH. This pilot study will enroll 60 individuals who qualify with a presenting systolic blood pressure of at least 170 mmHg, have an ICH, and can be evaluated and treatment initiated within 6 hours of onset of stroke symptoms. In a stepwise fashion, the scientists will investigate the potential consequences of controlling blood pressure with intravenous nicardipine at 3 sequential levels: 170 to 200 mmHg, 140 to 170 mmHg, and 110 to 140 mmHg. Twenty participants will be enrolled per level. Treatment will last 18 to 24 hours. Participants will stay in the hospital for about 7 days (including 24 hours in the intensive care unit for close monitoring) and will return for 1-hour follow-up visits at 30 days and at 90 days after discharge from the hospital. During these visits participants will receive neurological assessments to determine their functional outcome. For participants, the study will be completed after the 90-day follow-up visit.

Masking description

Open treatment assignment was employed because it is not safe to conceal SBP measurement. Patient data routinely entered by clinical staff were used to evaluate safety.

Intervention model description

Staged intensity levels of rapid intravenous antihypertensive control for elevated SBP in patients with intracerebral hemorrhage were implemented in 3 sequential treatment arms to assess the feasibility and tolerability (safety) of this treatment.

MeasureTime frameDescription
Total Number of Serious Adverse Events Within the Initial 72 Hours From Treatment Per Subjectfrom treatment initiation through 72 hoursSerious 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.
Particpants Who Achieve and Maintain the Systolic Blood Pressure Goals for Each Treatment Tier.Within 3 hours of symptom onset and sustained through 18-24 hours.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.
Number of Participants With Neurological Deteriorations (Decrease of 2 or More Points on the GCS Score or an Increase of 4 or More Points on the NIHSS Score) During the 24 Hour Treatment,within the first 72 hours of treatment initiationNeurological 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.

Recruitment details

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.

Pre-assignment details

Outcome results

Primary

Number of Participants With Neurological Deteriorations (Decrease of 2 or More Points on the GCS Score or an Increase of 4 or More Points on the NIHSS Score) During the 24 Hour Treatment,

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.

Time frame: 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.
