| Primary | Time to First Achieve Initial Prespecified SBP Target Range and 15% Reduction From Baseline Within First 30 Minutes | Time to first achieve the initial pre-specified systolic blood pressure (SBP) target range and a 15% SBP reduction from baseline is the time in minutes between the initiation of study medication and the time the patient first achieved both components. Median time was estimated using Kaplan Meier method. 95% two-sided confidence interval of the median time is from 'Simon and Lee, 1982'. If patients did not reach both components within 30 minutes from the initial treatment with study medication, or another antihypertensive agent was administered, the patient was censored at 30 minutes or the time when another antihypertensive agent is given, whichever came first. | mITT population: All randomized and eligible patients who were dosed with study drug and have a baseline SBP ≥160 mm Hg, at least one post-baseline on-treatment SBP measurement, and a confirmed diagnosis of AHF | Posted | | Median | 95% Confidence Interval | Minutes | | Initiation of study drug through the initial 30-minutes | | | | ID | Title | Description |

| OG000 | Clevidipine | Clevidipine was titrated to effect thereafter by doubling the dose every 3 minutes, per physician discretion and as tolerated by the patient, until the desired SBP target range was attained. The infusion rate could then be increased or decreased as needed in order to maintain blood pressure for minimum of 30 minutes and a maximum duration of 96 hours. The minimum infusion rate was 1 mg/h and maximum infusion rate was 32 mg/h. | | OG001 | Standard of Care | The selection of the standard of care (SOC) IV antihypertensive treatment agent was at the discretion of the investigator. The infusion was administered per the institution's treatment practice. Dose titrations were to be performed to the maximum allowed or tolerated dose in order to achieve SBP control within the patient-specified SBP target range within the first 30 minutes. SOC was to be administered for a minimum of 30 minutes and, if medically warranted, could continue beyond 96 hours at the investigator's discretion. |

| - OG00015.0(15.0 to 21.0)
- OG001NA(NA to NA)NA=Not Reached: Median time to achieve this goal could not be determined in the SOC IV therapy group because less than 50% (15/41; 36.6%) of patients achieved both the pre-specified target range and a 15% reduction in SBP within the first 30 minutes.
