About pegcetacoplan

Pegcetacoplan is a therapy targeting C3, the central protein in the complement cascade. It acts proximally in the complement cascade controlling both C3bmediated extravascular haemolysis and terminal complementmediated intravascular haemolysis. Pegcetacoplan is being evaluated in several clinical studies across haematology, ophthalmology, nephrology, and neurology. In May 2021, pegcetacoplan was approved as EMPAVELI™ in the US for the treatment of adults with paroxysmal nocturnal haemoglobinuria (PNH). The marketing authorisation application for pegcetacoplan for paroxysmal nocturnal haemoglobinuria (PNH) is under review by the European Medicines Agency (EMA). Pegcetacoplan was also granted Fast Track designation by the FDA for the treatment of geographic atrophy and received orphan drug designation for the treatment of C3 glomerulopathy by the FDA and EMA.

About Doptelet® (avatrombopag)

Doptelet is an orally administered thrombopoietin receptor agonist (TPO-RA) that mimics the biologic effects of TPO in stimulating the development and maturation of megakaryocytes, resulting in increased platelet count. It is approved by EMA and FDA for the treatment of thrombocytopenia in adult patients with chronic liver disease who are scheduled to undergo a procedure, and for the treatment of thrombocytopenia in adult patients with chronic immune thrombocytopenia (ITP) who have had an insufficient response to a previous treatment. Chronic ITP is a rare autoimmune bleeding disorder characterised by low number of platelets. The incidence of primary ITP in adults is 3.3/100 000 adults per year with a prevalence of 9.5 per 100 000 adults¹.
