A Phase 2 interventional study of Glyburide for Injection and Placebo in Ischemic Stroke and Malignant Edema, sponsored by Remedy Pharmaceuticals, Inc.. Completed at 17 sites in United States. Open to participants aged 18 Years to 80 Years. Per ClinicalTrials.gov, last updated 2024-11-12.
Sponsored by Remedy Pharmaceuticals, Inc. · Phase 2, Interventional, and Prevention
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.
The study population consists of participants with a clinical diagnosis of acute severe anterior circulation ischemic stroke, a baseline diffusion weighted image (DWI) lesion between 82 and 300 cm3, age 18-80 years, and time from symptom onset to start of study infusion of ≤10 hours. The study will enroll both participants that do not receive intravenous (IV) recombinant tissue plasminogen activator (rtPA) and those that receive IV rtPA within 4.5 hours of stroke.
Enrollment will be randomized controlling for site, age ≤60 (yes/no), and IV rtPA treatment at baseline (yes/no). Participants will be randomized equally between glyburide and placebo.
2,612 studies on the registry are indexed under Ischemic Stroke; 971 are open to participants now.
This study's enrollment of 86 is below the median of 120 across 1,776 interventional studies indexed under Ischemic Stroke.

Key Exclusion Criteria:
NOTE: Other protocol defined inclusion/exclusion criteria may apply
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².
Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.
Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.
Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.
On an ECG, the QT interval is the time the heart’s lower chambers take to activate electrically and recover in each beat. QTc is that time adjusted for heart rate (QTcF by Fridericia’s formula, QTcB by Bazett’s). Some medicines lengthen it, and a long QTc can raise the risk of a dangerous heart rhythm.
The study may name a correction formula and a limit in milliseconds, often around 450–480.
Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Ran from Jun 2013 to primary completion in Apr 2016, 33 months.
Of 41 industry-sponsored phase 2 interventional studies under Ischemic Stroke, half reached primary completion within 24 months of starting (the median), counting those still running; a quarter within 12 and three quarters within 35. This study's 33 months is above that.
Counting every sponsor, half of 124 studies reached it within 28 months; a quarter within 15 and three quarters within 39.
