Patients with congenital hearing loss could benefit from a gene therapy currently in development. Although there are approaches that could reverse the process in children and young people before it becomes severe, so far, adults do not have any treatment that prevents the progressive deterioration of auditory sensory cells caused by this disease.

Many patients with amyotrophic lateral sclerosis (ALS) or frontotemporal dementia (FTD) harbor the (G4C2)n pathogenic repeat expansion in the C9orf72 gene, which leads to aggregating dipeptide proteins, mainly poly-glycine-alanine (poly-GA).

Abata Therapeutics Inc. has obtained FDA clearance for its IND application enabling initiation of a first-in-human study of ABA-101 in patients with progressive multiple sclerosis (MS). A phase I study will open later this year.

Brains from people with heroin use disorder have an increased number of hypocretin (Hcrt, orexin) neurons, which in turn are significantly smaller than in healthy controls. Meanwhile, human narcolepsy is known to present an average 90% loss of Hcrt neurons and no risk for drug abuse or overdose, even under methamphetamine or methylphenidate prescription, because of a greatly reduced reward activation of the ventral tegmental area (VTA).
