1. First-in-human optogenetic therapy partially restores light sensitivity in blind RP patients.
In a 10-patient phase 1/2 study published in NEJM, a single eye injection of GS030 plus camera goggles improved light sensitivity in 7 participants; 6 met the threshold for a clinically meaningful gain [1][2][3]. Four of 8 tested patients did better on object tasks, but none could read or recognise faces [2][4]. See the lead article above.
2. Kenya confirms its first Ebola case, imported from Congo.
Health Minister Aden Duale said on October 6 that a Kenyan man who had lived in Congo for seven years tested positive in Nairobi and died; he had travelled by road to Kampala before flying to Nairobi [5][6]. Contacts, including family and health workers, plus 23 passengers and four crew from his flight are being traced [5][6]. Congo's outbreak has passed 8,000 cases and 4,000 deaths [5][6].
3. FDA approves tucatinib for HER2-positive breast cancer maintenance.
On October 7, the FDA approved tucatinib (Tukysa) with trastuzumab and pertuzumab as maintenance after induction therapy for unresectable locally advanced or metastatic HER2-positive breast cancer [7]. In the 654-patient HER2CLIMB-05 trial, median progression-free survival was 24.9 vs 16.3 months with placebo (HR 0.64); overall survival data were immature [7]. The label carries a boxed warning for hepatotoxicity [7].
4. WHO issues first global guidelines on child and adolescent obesity.
WHO does not recommend obesity medicines, bariatric surgery or weight-loss devices for children under 10 [8]. For ages 10–19, approved medicines may be considered only after a supervised lifestyle programme fails, and surgery only under strict conditions for severe obesity [8]. WHO estimates about 170 million people aged 5–19 had obesity in 2024 [8]. WHO officials said the medicine and surgery recommendations are conditional [9].
