入选标准
- •Informed Consent
- •Provide written informed consent (signed and dated). Patients should be assessed for their ability to give informed consent using the Evaluation to Sign Consent tool.
- •Is ≥25 and ≤60 years of age inclusive, of any gender, at the time of signing the informed consent.
- •Type of Indications and Disease Characteristics
- •Have SCA1, SCA3 or HD meeting one of the following criteria: a. SCA1 and SCA3: mild to moderate disease with a Scale for Assessment and Rating of Ataxia (SARA) score of ≥3 and ≤18 b. HD: early manifest, Stage I disease with a Total Functional Capacity (TFC) Score of ≥11 and ≤13 and a Unified Huntington’s Disease Rating Scale (UHDRS) Diagnostic Confidence Level (DCL) of
- •Have genetically confirmed disease, defined by increased cytosine, adenine, and guanine (CAG) repeat length in the disease-causing allele by direct DNA testing (detail see Section 8.6.1). For each indication the requirements are: a. SCA1: ≥41 contiguous, uninterrupted CAG repeats in ATXN1 b. SCA3: ≥61 repeats in ATXN3 c. HD: ≥36 CAG repeats in HTT. NOTE: Genetic testing will be performed during screening, which will serve as a reference for criterion.
- •Have good general health, in the opinion of the investigator, apart from having SCA1, SCA3, or HD. NOTE: Patients with chronic illness (e.g., hypertension) will be eligible if the illness is stable and well-controlled in the opinion of the investigator that will not impact the primary objectives of the trial.
- •Body weight of ≥50 kg and body mass index (BMI) within the range of 18-32 kg/m2 (inclusive).
- •Reproductive status and Contraceptive/Barrier Requirements
- •Is willing to follow contraceptive requirements per local regulations regarding the methods of contraception for those participating in clinical trials. In case local regulations deviate from the contraception methods listed in Section 10.4, local regulations apply and will be described in the Informed Consent Form (ICF). a. Male participants: Applicable for Europe (NOTE: details according to the Clinical Trial Facilitation Group [CTFG] Contraception Guidance Version 1.1, issued 2020; see Section 10.4): Non-sterilised males who are sexually active with a female partner of childbearing potential: Agreement to use a condom as a method of contraception during the entire period from first IMP (VO659) administration up to 90 days after the last IMP administration and not to donate sperm during this period. Additionally, contraception for the female partner of childbearing potential should be considered. b. Female participants: Applicable for Europe (NOTE: Details according to CTFG Contraception Guidance version 1.1, issued 2020; see Section 10.4): Women of childbearing potential: a negative result in a pregnancy test at screening and prior to each IMP administration AND agreement to practice a highly effective method of contraception during the entire period from informed consent up to 6 months after the last IMP administration. A woman is considered of childbearing potential, i.e., fertile, following menarche and until becoming postmenopausal unless permanently sterile. Permanent sterilisation methods include hysterectomy, bilateral salpingectomy, and bilateral oophorectomy. A postmenopausal state is defined as no menses for at least 12 months without an alternative medical cause. Women under the age of 55 years must have both no menses for at least 12 months and a follicle-stimulating hormone (FSH) level >40m IU/mL (while not on any therapy that may interfere with FSH levels) in order to confirm menopause. In the absence of 12 months of amenorrhea, an FSH measurement in itself is insufficient to establish menopause.
