入选标准
- •Patient able to provide informed consent, geographically accessible to the site and able and willing to comply with all study requirements of the protocol, including two lumbar punctures.
- •Satisfactory peripheral venous access; no central catheterization will be permitted.
- •Satisfactory CSF volume at screening (i.e., 1.5 mL minimum).
- •Maximum body weight ≤110 kg at baseline.
- •For female patients: not pregnant and have a negative pregnancy blood test (women of childbearing potential [WOCBP] only) at screening and baseline.
- •For female patients: must not be breastfeeding, have no intention of becoming pregnant during the study, and use acceptable methods of contraception or abstain from intercourse. WOCBP must agree to use highly effective contraception consisting of two forms of birth control, one of which must be a male barrier method such as a latex or polyurethane condom from the start of dosing throughout the clinical study period, and for 90 days after the final administration of study treatment. Women of non-childbearing potential (WONCBP) will be considered those who are sterilized or post-menopausal. A sterilized patient will have either undergone surgical sterilization (hysterectomy, bilateral oophorectomy, or bilateral salpingectomy; participant reported information) at least 90 days prior to baseline; postmenopausal patients will have been amenorrheic for > 12 consecutive months before screening and FSH levels > 30 IU/L. Essure® fallopian tube coil placement is not accepted as surgical sterilization because of the high failure rate.
- •Male patients must either declare and confirm abstinence or must be willing and able to use effective contraception. Male patients engaging in sexual intercourse with WOCBP, both the male patient and his female partner must use highly effective contraception consisting of 2 forms of birth control, one of which must be a male barrier method such as a latex or polyurethane condom from the start of dosing throughout the clinical study period, and for 90 days after the final administration of study treatment. Males who have had a vasectomy must have a confirmed zero sperm count or must agree after receiving the first dose of study drug either to use acceptable methods of contraception or abstain from intercourse.
- •For male patients: The patient must not donate sperm at any time from the start of dosing, throughout the clinical study period, and for 90 days after the final administration of study intervention.
- •Male or female, 18 years of age or older at the time of signing the ICF.
- •Patients diagnosed as having possible, probable, probable laboratory-supported, or definite ALS, either sporadic or familial, according to El Escorial Revised criteria.
- •Disease duration of ≤ 36 calendar months (i.e., ALS symptom onset to the baseline timepoint) at baseline.
- •King’s Clinical Staging Stage ≤3 at baseline.
- •Any NfL value available before screening should be compatible with the diagnosis of ALS (>10 pg/mL).
- •Serum NfL study value available at baseline.
- •SVC ≥ 55% predicted value as adjusted for gender, height, and age at baseline.
- •Patients who are being treated with riluzole or symptomatic treatment for ALS (including over the counter medication or supplements) must have been on a stable dose for at least 30 days before baseline. Riluzole-naïve patients or having stopped riluzole at least 2 weeks prior to screening are permitted in the study.
排除标准
- •Patients with any cognitive or psychological disorder, intellectual disability or other significant impairment that would result in an inability to understand and sign the informed consent.
- •Any contra-indication to glucose 5% and/or any hypersensitivity to any component of the IMP formulation.
- •Any known significant brain or spinal disease that would interfere with the lumbar puncture process, CSF circulation or safety assessment.
- •Any person who is an employee of the study sponsor or stakeholder partners involved in the conduct of the study, or an immediate relative of an investigator or study staff.
- •Minors, persons deprived of liberty by judicial or administrative decision, persons receiving psychiatric care and persons admitted to a health or social institution, adult patients under legal protection or unable to express consent.
- •Exposure to an investigational drug within 12 weeks prior to screening, or at least a period of 5 half-lives for the investigational drug, whichever is longer; for antisense therapy targeting SOD1, if the patient has completed treatment within 6 months of the screening visit. Any drug intended for ALS (other than riluzole and symptomatic treatment) will not be allowed.
- •Patient with a history of any clinically significant or unstable medical (including hepatic and renal), neurological, psychiatric condition, disorder or disease (other than ALS) or social circumstances that, based on the investigator's judgment, would 1) interfere with the patient's ability to comply with the protocol and all study procedures or 2) compromise study integrity or 3) pose a risk to the patient if they were to participate (e.g., previous acute coronary syndrome within 3 months of screening, major surgery within 2 months of screening) or physical examination, uncontrolled hypertension (blood pressure > 160/100 mm Hg), at screening or baseline.
- •History of malignancy within 3 years of screening, except for basal or squamous cell carcinoma of the skin or carcinoma in situ of the cervix that has been successfully treated. Patients with a history of other malignancies that have been treated with curative intent and which have no recurrence within 6 months may be eligible, based on the investigator’s judgement.
- •Any clinically significant abnormalities in screening laboratories, including hepatic and renal impairment (e.g., aspartate aminotransferase (AST) >3× upper limit of normal (ULN); alanine aminotransferase (ALT) >3 × ULN; total bilirubin >2 × ULN; serum creatinine >2.0 × ULN). Retesting may be performed, on discussion with the medical monitor.
- •Patient under anticoagulant treatment that cannot be held or stopped without putting at risk the patient’s life.
- •Positive test to human immunodeficiency virus (HIV) or current chronic/active infection with hepatitis C virus or hepatitis B virus.
- •Patients with active infections or, based on the investigator’s judgement, any active/uncontrolled inflammatory condition(s).
