简要总结
This is a dose escalation study to assess the safety, tolerability, pharmacokinetics and pharmacodynamics of SIF001, a monoclonal antibody with the potential to treat epilespy
详细描述
Nonclinical studies including disease animal model studies and toxicological studies indicate that SIF001 has the potential to be a therapeutical agent for epilepsy treatment through addressing the underlying pathology. This a phase 1 dose escalation study to assess the safety, tolerability, pharmacokinetics and pharmacodynamics of SIF001 in healthy subjects and in a patient cohort with epilepsy.

排除标准
- •Healthy Volunteers (Stage I and II (Phase 1a and 1b)):
- •Subjects with any unresolved history of clinically significant disease, in the opinion of the investigator.
- •Past or intended use of over-the-counter (OTC) or prescription medication (other than ≤ 2 g/day paracetamol [acetaminophen] or ≤ 800-mg/day ibuprofen), vitamins, and dietary or herbal supplements within 7 days or 5 half-lives of the respective drug, if known (whichever is longer), prior to dosing.
- •Patients with Epilepsy (Stage II (Phase 1b)):
- •Acute precipitant of seizure within the past 3 months prior to screening such as major trauma, hypoglycemia, hyperglycemia, cardiac arrest, or post-anoxia
- •All Subjects:
- •Any uncontrolled medical or psychiatric condition (e.g., hypertension, diabetes, chronic obstructive pulmonary disorder, asthma, depression) as judged by the investigator.
- •Any clinically significant findings in medical examination, including physical examination, 12-lead ECG, vital signs, clinical laboratory tests. Specifically:

- •Known history of hypersensitivity or anaphylactic reaction to intravenous medications, biologicals, or fluids.
- •History of any clinically significant disease or disorder which, in the opinion of the investigators, may either put the subject at risk because of participation in the study, or influence the results or the subject's ability to participate in the study.
- •History of status epilepticus within 2 years of screening
- •Known history of suicidality within 2 years of screening, or answering "yes" to questions 4 and 5 of the Columbia Suicide Severity Rating Scale (C-SSRS)
- •Unable to complete this study for other reasons or the investigator believes that the subject should be excluded.
