Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The HEMERA-1 Extension (Part III) is a prospective, open-label, multicenter study to evaluate safety of two doses of PP-007 in Acute Ischemic Stroke (AIS) subjects receiving Intravenous Thrombolysis (IVT) or mechanical thrombectomy (MT) or IVT+MT as standard of care (SOC). Subjects will receive two doses of PP-007 infusion 24 ± 6 hours apart in addition to the site-specific SOC protocol. PP-007 is PEGylated bovine carboxyhemoglobin and will be administered via IV infusion. The effects on collateral flow, infarct size and functional outcomes will be evaluated.
