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.
OTL-200 is a gene therapy that involves extraction of certain stem cells from a patient’s bone marrow or blood. These stem cells are genetically modified and then returned to the patient by intravenous infusion to deliver the corrected version of the gene to the cells in charge of creating key proteins. The corrected cells then produce the protein that was missing or defective prior to treatment, aiming to halt disease progression or modify its natural course. If licensed, OTL-200 will offer a potentially curative treatment option for patients with MLD, who currently have no effective therapies available.
