"We Are Committed To Transforming Lives For People Living With Rare Diseases, And This Is A Testament To The Medical Innovation That Science Can Bring."Topline Results From The Pivotal Xtend-1 Phase 3 Study Demonstrated That Efanesoctocog Alfa Met The Primary Endpoint, Showing A Clinically Meaningful Prevention Of Bleeds In People With Severe Haemophilia A Over A 52-Week Period. Importantly, The Key Secondary Endpoint Was Also Met, Demonstrating That Efanesoctocog Alfa Was Superior To Prior Prophylactic Factor Viii Replacement Therapy In Preventing Bleeding Events Based On An Intra-Patient Comparison. Efanesoctocog Alfa Was Well-Tolerated, And Inhibitor Development To Factor Viii Was Not Detected. The Most Common Treatment-Emergent Adverse Events (>5 Per Cent Of Participants Overall) Were Headache, Arthralgia, Fall, And Back Pain.Data From The Xtend-1 Phase 3 Study Are Expected To Be Shared At An Upcoming Medical Meeting And Will Serve As The Basis For Regulatory Submission To The Fda By Mid-Year 2022.

The European Commission Also Granted Efanesoctocog Alfa Orphan Drug Designation In June 2019. Regulatory Submission In The Eu Will Follow Availability Of Data From The Ongoing Xtend-Kids Paediatric Study, Expected In 2023.Haemophilia A Occurs In About One In 5,000 Male Births Annually, And More Rarely In Females. It Is A Lifelong Condition In Which The Ability Of A Person'S Blood To Clot Is Impaired Due To A Coagulation Factor Deficiency. People With Haemophilia Can Experience Bleeding Episodes That Can Cause Pain, Irreversible Joint Damage, And Life-Threatening Haemorrhages.
