入选标准
- •Capable of, and willing to, provide written informed consent and comply with study procedures, including visits to the study site and visit requirements
- •Women of childbearing potential (WOCBP) and male participants with female partners who are WOCBP (based on gender assignation at birth) must agree to use highly effective (<1% failure rate) contraception for at least 30 days prior to the first dose of study medication and for the fixed period of one year following administration of the study medication. Male participants (based on gender assignation at birth) must refrain from sperm donation for the fixed period of one year following administration of the study medication; WOCBP (based on gender assignation at birth) must have a negative serum pregnancy test at Screening and a negative urine pregnancy test at Baseline (Day 1)
- •Women of nonchildbearing potential must be either surgically sterile (hysterectomy, bilateral tubal ligation, salpingectomy, and/or bilateral oophorectomy at least 26 weeks before Screening) or postmenopausal, defined as spontaneous amenorrhea for at least 2 years, with follicle-stimulating hormone (FSH) level in the postmenopausal range at Screening based on the central laboratory's range
- •Men and WOCBP (i.e., ovulating, premenopausal, and not surgically sterile) must use a highly effective method of contraception consistently and correctly for the duration of fixed period of one year following administration of study medication. Highly effective methods of contraception are those that, alone or in combination, result in a failure rate of less than 1% per year when used consistently and correctly (i.e., perfect use) o Acceptable forms of contraception for participating WOCBP include the following: ▪ Combined (estrogen and progestogen containing) oral, intravaginal, or transdermal hormonal contraception associated with inhibition of ovulation ▪ Oral, injectable, or implantable progestogen-only hormonal contraception associated with inhibition of ovulation ▪ Intrauterine device ▪ Intrauterine hormone-releasing system ▪ Bilateral tubal ligation or bilateral tubal occlusion (performed at least 3 months prior to Screening) ▪ Vasectomized partner (performed at least 3 months prior to Screening) ▪ Sexual abstinence (no sexual intercourse) o Acceptable forms of contraception for male participants include: ▪ Sexual abstinence (no sexual intercourse) ▪ History of vasectomy (performed at least 3 months prior to Screening) plus external condom ▪ Condom with spermicide used together with highly effective female contraceptive methods if the female partner(s) is of childbearing potential (see above for list of acceptable female contraceptive methods)
- •Women who are in exclusively same-sex relationships (as their preferred and usual lifestyle) are not required to use contraception; male participants in same sex relationships are also required to use an external condom to prevent exposure of their partner to the IMP
- •Men must agree to abstain from sperm donation for the fixed period of one year following administration of the study medication and are required to use an external condom when engaging in any activity that allows for passage of ejaculate to another person during the main study period
- •Women must agree to abstain from egg donation for the duration of the study
- •Women of childbearing potential cannot be pregnant or lactating/breastfeeding and must have a negative result for the serum pregnancy test (P-human chorionic gonadotropin [P-HCG]) at Screening
- •Must have pneumococcal pneumonia and shingles vaccination coverage within 10 years prior to Screening or consent to these vaccinations to be performed during the Screening period
- •Up to date with age and gender appropriate cancer screening as per local standard of care based on Principal Investigator's (PI) judgment
- •Male or female ≥ 18 years of age
- •Has a diagnosis of ALS according to the El Escorial criteria (Brooks, et al., 2000) (probable, laboratory results supported; clinically probable, clinically definite)
- •Confirmed absence of FUS and SOD1 ALS by exclusion of pathogenic or possible pathogenic genetic mutations (per central laboratory at Screening or previous result provided by Clinical Laboratory Improvement Amendments [CLIA] certified laboratory, or EU/United Kingdom equivalent accreditation)
- •A maximum of 18 months since first appearance of weakness (e.g., limb weakness, dysarthria, dysphagia, shortness of breath)

- •Treatment Research Initiative to Cure ALS (TRICALS) risk score between −2 and −6 at Screening
- •Has a reliable caregiver/partner/legal representative willing and able to support the participant in participation in the study and to give informed consent on behalf of the participant in the case that disease progression prevents the participant of giving consent (local legal rules will apply). This person should have regular contact with the participant and must sign a separate partner informed consent form (ICF) indicating that she/he understands the study requirements and is willing to participate
- •Treatment with riluzole and/or edaravone is allowed if treatment was started and maintained at a stable regimen for at least 4 weeks for riluzole and/or for a full treatment cycle for edaravone (i.e., 14 days on AND 14 days off) before the Screening visit
排除标准
- •Diagnosis of a significant CNS or peripheral nervous system disease other than ALS that may be a cause for the participant's ALS symptoms or may confound study objectives
- •Any other abnormal Screening laboratory test result deemed clinically significant by the Investigator
- •Any type of prior gene or cell therapy
- •Immunizations (live vaccines) in the 4 weeks prior to Screening. Note: Pneumococcal and shingles vaccine administrations are allowed during the Screening period
- •Pregnant or breastfeeding
- •Use of blood thinners (e.g., warfarin, heparin, and novel oral anticoagulants) in the 2 weeks prior to Screening LP or (ICM) procedure, or the anticipated need to initiate blood thinners during the study. Antiplatelet therapies (e.g., prophylactic aspirin, clopidogrel) are acceptable if the participant is medically able to temporarily stop 48 hours to 7 days (depending on the antiplatelet medication used) prior to and at least 48 hours after intracisternal injection and LP

- •Note: use of medical marijuana is permitted provided that the participant is on a stable regimen. It is also permitted if the participant resides in a state in which the recreational use of marijuana is legalized, so long as the participant does not meet the drug abuse criteria (as defined in the DSM-5)
- •Generally frail or has any medical condition, for which in view of the Investigator, participation in the study would not be in the best interest of the participant or is likely to prohibit further participation during the study
- •Known or suspected allergy or intolerance to the IMP (VTx-002 or constituents)
