Tralesinidase alfa is in clinical development for the treatment of patients with mucopolysaccharidosis type IIIB (MPS IIIB) also known as Sanfilippo syndrome type B. MPS IIIB is a rare and progressive genetic disorder caused by the deficiency of one of the enzymes needed to break down complex sugar molecules called mucopolysaccharides. Clinically, patients have behavioural problems, intellectual deterioration, sleep disorders, hearing impairment, facial dysmorphism, organomegaly, bowel disturbances, mild skeletal changes, and shortened life span. The clinical severity ranges from mild to severe.
Tralesinidase alfa is an investigational enzyme replacement therapy (ERT) designed to replace the faulty enzyme with a healthy one in patients with MPS IIIB. Tralesinidase alfa is delivered directly to the fluid surrounding the brain (cerebrospinal fluid). If licensed, tralesinidase alfa will offer new therapy option for patients with MPS IIIB who currently have no treatment options.
Ozanimod, administered orally, is a new sphingosine 1-phosphate (S1P) receptor modulator. Treatment with S1P modulators is believed to work by interfering with signalling pathways that contribute to tissue inflammation. If licensed, ozanimod will offer an additional treatment option for adult patients with moderate to severe UC who have had an inadequate response, lost response to, or were intolerant to conventional therapy or a tumour necrosis factor-alpha (TNF) antagonist. In one phase II clinical trial, ozanimod at a daily dose of 1mg resulted in a slightly higher rate of clinical remission of ulcerative colitis than placebo.
