This first-in-patient phase 2a pilot study will assess the safety and tolerability of MW01-6-189WH (hereafter called MW189) in patients with Intracerebral Hemorrhage (ICH).
This first-in-patient phase 2a pilot study will assess the safety and tolerability of MW01-6-189WH (hereafter called MW189) in patients with Intracerebral Hemorrhage (ICH).
This study will monitor exploratory radiographic and clinical endpoints, explore the use of biochemical biomarkers to demonstrate target engagement and biological response to a potential new therapy targeted to neuroinflammation and synaptic dysfunction mechanisms.
MW189 is a novel small molecule drug candidate developed as a selective suppressor of disease-and injury-induced proinflammatory cytokine overproduction associated with destructive neuroinflammation/synaptic dysfunction cycles. In animal models of acute brain injuries such as ICH and Traumatic Brain Injury (TBI), MW189 attenuates neuroinflammation, reduces cerebral edema, and improves functional and cognitive performance. The investigators seek to establish if these targets are modified in humans with ICH.
457 studies on the registry are indexed under Cerebral Hemorrhage; 172 are open to participants now.
This study's planned enrollment of 120 is above the median of 100 across 269 interventional studies indexed under Cerebral Hemorrhage.

Exclusion Criteria:
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.
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.
A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.
Read whether the line is about a condition or about medicines, and which medicines and doses it means.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Started Oct 2022 (actual). Primary completion is estimated for Nov 2026, 49 months after the start.
Of 24 phase 2 interventional studies under Cerebral Hemorrhage, half reached primary completion within 38 months of starting (the median), counting those still running; a quarter within 28 and three quarters within 62. This study's planned 49 months is above that.
