Chinese scientist probed after girl dies following gene-editing trial

Where things stand

A Chinese university has opened an inquiry into one of its scientists after reports that a six-year-old girl died shortly after receiving experimental gene-editing treatment. The medical school of Shanghai Jiao Tong University said it would carry out a thorough investigation of the clinical case, following a South China Morning Post report that the girl, identified as Mei, died days after the therapy was administered and that a leading scientist involved is now under investigation by his university. Beyond that, the institution has not publicly set out what it will examine or on what timetable. At this stage the account rests largely on the South China Morning Post's reporting, and key details — including the nature of the therapy, the circumstances of the girl's death and the identity and role of the scientist under scrutiny — remain unconfirmed by the university or other authorities. No findings, disciplinary measures or regulatory action have been announced. The direction of the topic now depends on what the university's investigation establishes about the conduct of the trial and whether wider medical or regulatory bodies become involved.

Gene-editing therapies alter a patient's DNA in an attempt to correct the underlying cause of a disease, and treatments that have not completed regulatory approval are administered only within experimental clinical trials. Such trials are subject to ethical review and oversight rules governing consent, patient selection and the reporting of adverse events, which makes the death of a participant a matter for institutional investigation. In this case the patient was a six-year-old girl, referred to in reports as Mei, who according to the South China Morning Post died days after receiving the treatment. The scientist said to have been involved is affiliated with Shanghai Jiao Tong University, whose medical school has committed to investigating the case. It is not publicly confirmed what condition was being treated, what the therapy consisted of, or whether the death has been causally linked to it.
