Rhea-AI Summary

XBiotech Inc. has initiated a randomized, open-label, placebo-controlled clinical study for Hutrukin, a novel therapy aimed at reducing brain injury from ischemic stroke. With over 10 million cases of ischemic strokes annually, the need for effective treatments is critical. Hutrukin seeks to mitigate reperfusion injury, a common complication following clot-removal procedures, by targeting inflammation before blood flow is restored. The Phase I study will evaluate three dosing levels for safety and pharmacokinetics, with results guiding further research phases. XBiotech leverages its proprietary True Human™ antibody technology to explore innovative treatments across various diseases.

Positive
  • Initiated Phase I clinical study for Hutrukin aimed at reducing brain injury from ischemic stroke.
  • Potential to address unmet medical need in stroke management by targeting reperfusion injury.
Negative
  • Clinical study is in early Phase I, outcomes and efficacy remain uncertain until further evaluation.

Hutrukin, A Therapy Discovered and Manufactured at XBiotech, Is Aimed to Reduce Brain Injury after Stroke

AUSTIN, Texas, April 17, 2023 (GLOBE NEWSWIRE) -- XBiotech Inc. (NASDAQ: XBIT) has enrolled the first subject in a randomized, open-label, placebo-controlled dose escalation clinical study to evaluate safety and pharmacokinetics of Hutrukin.

Hutrukin is being developed as a novel treatment to reduce brain injury following ischemic stroke. There are more than 10 million ischemic strokes each year—the leading cause of death and morbidity in the world today. An ischemic stroke occurs when a blood clot forms in a blood vessel that supplies blood flow to brain. Blockage of blood flow to the brain results in brain injury, loss of brain function or death.

Emergency use of “clot-busting” drugs or mechanical catheters to re-open arteries after a stroke is associated with a phenomenon known as reperfusion injury. Reperfusion injury is where the return of blood supply after removing the clot from the artery results in increased brain injury or death. Reperfusion injury is believed to be the result of a massive inflammatory response caused by blood cells as they flow back into the region of the brain that was deprived of blood supply (and oxygen).

Hutrukin therapy is intended to be provided immediately prior to the clot-busting procedure, where the drug may reduce inflammatory injury associated with reperfusion. There is currently no drug known to be effective to reduce reperfusion injury. Hutrukin could, therefore, potentially represent a significant advance in the management of stroke patients.

The current Phase I study will evaluate three dose levels of Hutrukin for safety and will measure the corresponding blood levels of Hutrukin with increasing doses. Findings will guide dosing and safety expectations for the next phase of studies.
