Imlifidase is in clinical development for enabling kidney transplantation in highly sensitised patients with chronic kidney disease (CKD). CKD is a long-term irreversible condition where the kidneys do not work as well as they should. Kidney transplantation is considered to be treatment of choice for patients with end stage kidney disease. Many patients on the waiting list for organ transplantation carry antibodies to human leukocyte antigen (HLA), which is known as being ‘sensitised.’ Patients who are highly sensitised may find it difficult getting a donor and may not be able to receive a transplant due to increased risk of kidney rejection.
Imlifidase is made of an enzyme derived from the bacterium called Streptococcus pyogenes. It specifically cleaves all human subclasses of proteins called immunoglobulin IgG. This mechanism inhibits all IgG mediated immunity and prevents rejection of a transplanted kidney. If licensed, imlifidase will offer a treatment that enables kidney transplantation in highly sensitised patients with CKD.
Filgotinib is in clinical development for the treatment of patients with moderately to severely active ulcerative colitis. Ulcerative colitis is a type of inflammatory bowel disease that causes inflammation and ulcers in the bowel and rectum which can cause diarrhoea, abdominal pain and faecal urgency or incontinence. The symptoms of ulcerative colitis often follow a pattern of relapse and remission where they have periods of none or mild symptoms followed by periods of increased symptoms flare-up (‘active’). There are no curative therapies for ulcerative colitis and current treatment aims to relieve symptoms during a flare-up and maintain remission by preventing symptoms from returning.
