The Symptomatic Cerebral Cavernous Malformation Trial of REC-994 (SYCAMORE)
July 18, 2023 updated by: Recursion Pharmaceuticals Inc.
A Two-Part Study of REC-994 in the Treatment of Adults With Symptomatic Cerebral Cavernous Malformation (CCM); Part 1: A Phase 2 Randomized, Double-Blind, Placebo-Controlled Clinical Trial to Evaluate the Safety, Efficacy and Pharmacokinetics of Two Doses of REC-994; Part 2: A Long-Term Blinded Extension Clinical Trial to Evaluate Long-Term Safety Tolerability and Efficacy of REC-994
This is a two-part, multi-center, randomized, double-blind, placebo-controlled study to investigate the safety, efficacy and pharmacokinetics of REC-994 (200 mg and 400 mg) compared to placebo in subjects with symptomatic cerebral cavernous malformation (CCM).

Participation Criteria
Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.
Eligibility Criteria
Ages Eligible for Study
18 years and older (Adult, Older Adult)
Accepts Healthy Volunteers
No
Description
Inclusion criteria:
- 18 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
Exclusion Criteria:
- 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)
