Abliva announced that NV354, the company's second candidate within the primary mitochondrial disease space, will progress to clinical phase. NV354 is initially being developed for the fatal Leigh syndrome, a disease that usually debuts before the age of 2 and patients often die before the age of 5. With NV354 about to join Abliva's leading candidate against primary mitochondrial disease, KL1333, in clinical development, BioStock takes a closer look at the candidate.
