NCT05070260

Brief Summary

A randomized, double blind, multicenter, multinational, placebo controlled, parallel group, single dose, adaptive phase II/III study. The study evaluates the efficacy and safety of a fixed dose of glenzocimab (1000 mg IV over 6 hrs including initial bolus of 15 minutes) on top of the best standard of care.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Adult male or female patients ≥ 18 years (i.e., at least 18 years old at time of randomization)
  • Having given their own written consent, or legal representative consent, and in any case, in strict accordance with country-specific legal requirements,
  • Presenting with an acute disabling ischemic stroke either in the anterior or in posterior circulation, with or without visible occlusion, with a known time of onset, that is ≤ 4.5 hrs
  • Presenting with a pre-IVT NIHSS ≥ 6
  • In whom IVT is or has been initiated, whether or not patients are additionally eligible to mechanical thrombectomy (MT+ IVT), according to the recommendation of the last guidelines (ASA and ESO recommandations),
  • Women of childbearing potential (WOCBP) must have a negative serum/urine pregnancy test at baseline. Women of childbearing potential, i.e., fertile, are defined as women following menarche and until becoming post-menopausal unless permanently sterile, i.e., having undergone hysterectomy, bilateral salpingectomy and bilateral oophorectomy
  • Post-menopausal women defined as not having menses for 12 months without an alternative medical cause. For WOCBP, a highly effective birth control method should be in place that can achieve a failure rate of less than 1% per year that should last for at least 2 months after IMP administration.
  • Birth control methods which may be considered as highly effective in WOCBP include:
  • combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation (intravaginal, transdermal),
  • progestogen-only hormonal contraception associated with inhibition of ovulation (injectable, implantable)
  • intrauterine device (IUD),
  • intrauterine hormone-releasing system (IUS),
  • bilateral tubal occlusion,
  • vasectomized partner,
  • Birth control methods which may be considered as highly effective for men and that should last for 4 months after IMP administration include:
  • +4 more criteria

You may not qualify if:

  • Coma, or NIHSS \>25,
  • Patients \< 18 years,
  • Protected adults under guardianship or curatorship,
  • Prior ischemic stroke within the past 3 months,
  • mRS pre-stroke known to be ≥ 2,
  • Large (more than 1/3 of the middle cerebral artery) regions of clear hypodensity on Baseline Computed Tomography Angiography (CTA) or Magnetic Resonance Imaging (MRI) or with vascular injection (MRA),
  • Significant mass effect with midline shift,
  • Stroke of hemorrhagic origin,
  • Patients likely to require dual antiplatelet therapy (DAPT) within the first 24 hrs after cessation of glenzocimab or placebo infusion for e.g., carotid stenting,
  • Known renal insufficiency (Grades 4-5 - severe or terminal with a creatinine clearance \< 30 mL/min using Cockroft formula),
  • Known allergic reaction to contrast agents,
  • Patients under anti-coagulant therapy, except preventative doses of injectable low molecular weight heparin (LMWH),
  • Known ongoing treatment with a mAb,
  • Prior cardiopulmonary resuscitation \< 10 days,
  • Childbirth within \< 10 days,
  • +5 more criteria
