异染性脑白质营养不良
Metachromatic leukodystrophy
定义 英文原文(暂无中文)
A rare lysosomal disease characterized by accumulation of sulfatides in the central and peripheral nervous system due to deficiency of the enzyme arylsulfatase A, leading to demyelination. Three clinical subtypes can be distinguished based on the age of onset: late infantile, juvenile, and adult. Lead symptoms are deterioration in motor or cognitive function or behavioral problems, depending on the subtype, all eventually culminating in a decerebrated state and death after a highly variable disease course and duration. Mode of inheritance is autosomal recessive.

境外已获批用于本病的药物 2L2
欧盟 1 项、美国 1 项。同一药物在两地各批一次的,会分别列出。
「境外已获批」不等于「在中国能用」。中间隔着进口注册、临床急需境外新药通道、海南博鳌乐城国际医疗旅游先行区等几条路径,各有各的条件与费用。这一节能确定地告诉你的只有一件事:这个病在世界范围内已经有获得批准的药物,它叫什么名字。拿这个名字去问主治医生,是下一步最省力的做法。
药名一律保留英文原文,不作翻译——中国的药品通用名与英文名的音译经常不一致,译错会让人去找一个不存在的药。

已获孤儿药资格、尚未获批的在研药物(3 项)
孤儿药资格只是一种监管身份——它意味着监管机构认可这是罕见病用药并给予研发激励,不代表这个药已被证明有效,也不代表将来一定能上市。绝大多数最终不会成药。列在这里是为了看清有哪些方向正在被尝试。
数据来自欧洲药品管理局(EMA)的药品与孤儿药资格公开导出表,以及美国 FDA 孤儿药资格数据库。两边口径不同:欧盟一侧取的是当前状态仍为「已授权」的药品;美国一侧记录的是「曾获批准」这一事实,FDA 的公开表不追踪药物此后是否退市(例如 Relyvrio 于 2024 年撤市,表中仍记为已获批)。请以官方记录页为准。
在中国开展的临床试验 3L2
按病名在 ClinicalTrials.gov 检索、并校验研究中心含中国大陆而来。登记状态不等于现在真的能入组——务必按 NCT 号到原站核实,并与主治医生商量。

中国境外的在招试验 9L2
这些试验在中国没有研究中心,通常无法直接报名——入组一般要求在当地居住并接受随访。列在这里是因为它另有用处:看清楚全世界正在试哪些药、做到了哪一期、由谁在做。把药名和 NCT 编号记下来去问主治医生,或据此进一步查该药是否已在境外获批、是否有拓展性用药(expanded access)通道。
