Clinical research
Being tested in people in registered clinical trials. Being in trials is not evidence that a treatment works or is safe.
本试验正在测试什么
The first time CRISPR was injected directly into a human organ — under the retina, to remove a faulty piece of a gene causing severe inherited blindness. Some participants saw meaningfully better. The programme was later discontinued because too few people in the world have that exact mutation.
An open-label, single ascending dose Phase 1/2 study of EDIT-101, delivered by subretinal AAV5 injection, in participants with CEP290-associated Leber congenital amaurosis type 10. Published results reported clinically meaningful improvement in visual function in a subset of participants with an acceptable safety profile. Editas subsequently discontinued development for population-size reasons.

试验结果意味着什么，又不意味着什么
早期试验结果来自少量参与者和较短的随访周期，随着人数增加和时间延长，结论可能发生变化。正在招募、进行中甚至已完成的试验，并不代表某种疗法已被证实有效。入组标准十分严格，是否符合条件由试验机构决定，而非由网站判断。
