Interventions
Eligibility Criteria
You may qualify if:
- years of age or older with anatomic CCM lesions demonstrated by brain MRI
- Have symptomatic CCM
- Have provided written informed consent to participate in the study
- Have not participated in a clinical trial utilizing an investigational agent within 28 days or within 5 half-lives of the investigational drug (whichever is longer) prior to Screening
You may not qualify if:
- Symptoms deemed by the study Investigator to be caused exclusively by irreversible neuronal damage from prior stroke or neurosurgical instrumentation
- History of cranial irradiation or surgical/radiosurgical treatment of the primary symptomatic CCM lesion
- Pregnant or breast feeding
- Be unable or unwilling to participate in MRI assessments (e.g., claustrophobia, metal implant or implanted cardiac pacemaker)
- Liver dysfunction or active liver disease as defined by baseline serum transaminases \>2x upper limit of normal (ULN)
- Have moderately or severely impaired renal function (estimated glomerular filtration rate \[eGFR\] \<60ml/min) or active renal disease or have previously received a kidney transplant
- Have had a previous diagnosis of skeletal muscle disorders (myopathy) of any cause or have a baseline creatine kinase level \> 5x ULN
- History of alcohol or substance abuse within 1 year prior to screening
- Clinically significant laboratory abnormality
- Have had an intracerebral hemorrhage within 3 months of screening or any brain surgery within 6 months of screening (not including the primary symptomatic CCM lesion)
