recruiting iconRECRUITING


This is a randomized, multi-center, prospective, double blind study. The primary objective is to assess the efficacy and safety of glyburide (RP-1127) compared to placebo in participants with a severe anterior circulation ischemic stroke who are likely to develop malignant edema.This objective will be addressed by comparing the proportion of glyburide treated particpants and placebo treated participants with a Day 90 modified Rankin Scale (mRS) ≤ 4 without decompressive craniectomy (DC). The secondary objective is to assess the efficacy of RP-1127 compared to placebo in participants with a severe anterior circulation ischemic stroke who were likely to develop malignant edema.

Official Title

A Randomized, Multi-Center, Prospective, Double Blind, Phase II Trial of RP- 1127 (Glyburide for Injection) in Patients With a Severe Anterior Circulation Ischemic Stroke Who Are Likely to Develop Malignant Edema

Eligibility Criteria

Ages Eligible for Study: 18 Years to 80 Years
Sexes Eligible for Study: All
Accepts Healthy Volunteers: No
Inclusion Criteria:
  1. - A clinical diagnosis of acute ischemic stroke in the MCA territory (PCA and/or ACA territory involvement in addition to primary MCA territory stroke is acceptable). - Prior to stroke, no disability, or no significant disability despite symptoms (able to carry out all usual duties and activities). - A baseline DWI lesion between 82 and 300 cm3 on MRI. - Patients treated with IV rtPA should meet established criteria for IV rtPA administration in the 0-3 and 3-4.5 hr time periods at the time of rtPA administration (if rtPA is administered in the 3-4.5 hr time window, the NIHSS must be ≤ 25 at the time of rtPA administration). - The time to the start of infusion of Study Drug must be ≤ 10 hours after time of symptom onset, if known, or the time last seen well [termed "time last known at neurologic baseline" (TLK@B)]. - Provision of written informed consent by a legally authorized representative according to institutional guidelines and national regulations. Key
Exclusion Criteria:
  1. - Commitment to decompressive craniectomy (DC) prior to enrollment, or following enrollment and prior to start of Study Drug. - Treatment with intra-arterial (IA) rtPA or by mechanical means for clot disruption. - Patients unable to tolerate MRI scanning, e.g. those with pacemakers or automatic defibrillators. - Evidence (clinical or imaging) of concurrent infarction in the contralateral hemisphere deemed by the investigator to be sufficiently serious so as to affect functional outcome. - Clinical signs of herniation, e.g. one or two dilated, fixed pupils; unconsciousness (i.e., ≥ 2 on item 1a on the NIHSS); and/or loss of other brain stem reflexes attributable to edema or herniation according to the investigator's judgment. - Hemorrhage (other than small petechial hemorrhages) on CT/MRI, or CT/MRI evidence of anteroseptal/pineal shift greater ≥2 mm prior to enrollment that is due to cerebral edema. - Severe renal disorder from the patient's history (e.g. dialysis) or eGFR of < 30 mL/min/1.73 m2. - Severe liver disease or ALT >3 times normal, or bilirubin >2 times normal. - Blood glucose <55 mg/dL at enrollment or immediately prior to administration of Study Drug, or a clinically significant history of hypoglycemia. - Acute ST elevation myocardial infarction, and/or acute decompensated HF, and/or QTc>520 ms, and/or known history of cardiac arrest (PEA, VT, VF, asystole), and/or admission for an ACS, MI, or coronary intervention (PCI or coronary artery surgery) within the past 3 months. - Known sulfonylurea treatment within 7 days. Sulfonylureas include glyburide /glibenclamide (Diabeta, Glynase); glyburide plus metformin (Glucovance); glimepiride (Amaryl); repaglinide (Prandin); netaglinide (Starlix); glipizide (Glucotrol, GlibeneseR, MinodiabR); gliclazide (DiamicronR); tolbutamide (Orinase, Tolinase); glibornuride (Glutril). - Known allergy to sulfa or specific allergy to sulfonylurea drugs. - Known G6PD enzyme deficiency. - Pregnant women. Women must be either post-menopausal (as confirmed by the LAR), permanently sterilized or, if ≤ 50 years old must have a negative test for pregnancy obtained before enrollment. - Breast-feeding women who do not agree (or their LAR does not agree) to stop breast- feeding during Study Drug infusion and for 7 days following the end of Study Drug infusion. - Patients already enrolled in a non-observation-only stroke study, or with life-expectancy <3 months not related to current stroke, or those unlikely to be compliant with follow up. - Patients currently receiving an investigational drug. - Patients in whom a peripheral IV line cannot be placed. - Mentally incompetent (prior to qualifying stroke) patients and wards of the state. - Patients who, in the opinion of the investigator, are not suitable for the study (reason to be documented). NOTE: Other protocol defined inclusion/exclusion criteria may apply
