A Research Study to Gather Scientific Information About the Efficacy, Safety, and Tolerability of the Investigational Drug APL-2 In Treating Patients With Paroxysmal Nocturnal Hemoglobinuria (PNH), a Disease Associated With Anemia, In A Randomly Assigned Comparison With the Current Standard of Care Treatment Approved for PNH At Multiple Research Centres.
- Conditions
- PNH is an acquired, rare, clonal, non-malignant hematologic disease characterized by complement-mediated RBC hemolysis with or without hemoglobinuria, an increased susceptibility to thrombotic episodes, and/or some degree of bone marrow dysfunction.PNH is caused by complement-mediated lysis of erythrocyte clones lacking functional CD55 and CD59 on their surface. These RBCs are particularly susceptible to the MAC and have been shown to lyse readily in the presence of complement activation.Therapeutic area: Diseases [C] - Blood and lymphatic diseases [C15]MedDRA version: 21.1Level: LLTClassification code 10055629Term: Paroxysmal nocturnal hemoglobinuriaSystem Organ Class: 100000004857
