Voydeya is a first-in-class, oral, Factor D inhibitor developed as an add-on to standard-of-care Ultomiris or Soliris (eculizumab) to address the needs of the approximately 10-20% of patients with PNH who experience clinically significant extravascular haemolysis (EVH) while treated with a C5 inhibitor.

Professor Hubert Schrezenmeier, MD, Medical Director,
The ALPHA Phase III trial evaluated the efficacy and safety of Voydeya as add-on to Ultomiris or Soliris in patients with PNH who experienced clinically significant EVH. Results showed that Voydeya met the primary endpoint of change in haemoglobin from baseline to week 12 and all key secondary endpoints, including transfusion avoidance and change in Functional Assessment of Chronic Illness Therapy - Fatigue (FACIT-Fatigue) score.2
Results from the ALPHA Phase III trial showed Voydeya was generally well tolerated, and no new safety concerns were identified. In the trial, the most common treatment-emergent adverse events were headache, nausea, arthralgia and diarrhoea.2

Notes
PNH
PNH is a rare, chronic, progressive and potentially life-threatening blood disorder. It is characterised by red blood cell destruction within blood vessels (also known as intravascular haemolysis) and white blood cell and platelet activation, which can result in thrombosis (blood clots).
PNH is caused by an acquired genetic mutation that may happen any time after birth and results in the production of abnormal blood cells that are missing important protective blood cell surface proteins. These missing proteins enable the complement system, which is part of the immune system and is essential to the body's defence against infection, to 'attack' and destroy or activate these abnormal blood cells.4 Living with PNH can be debilitating, and signs and symptoms may include blood clots, abdominal pain, difficulty swallowing, erectile dysfunction, shortness of breath, excessive fatigue, anaemia and dark-coloured urine.
Clinically Significant EVH
EVH, the removal of red blood cells outside of the blood vessels, can sometimes occur in PNH patients who are treated with C5 inhibitors.9,10 Since C5 inhibition enables PNH red blood cells to survive and circulate, EVH may occur when these now surviving PNH red blood cells are marked by proteins in the complement system for removal by the spleen and liver.4,6,11 PNH patients with EVH may continue to experience anaemia, which can have various causes, and may require blood transfusions.9,10,12,13 A small subset of people living with PNH who are treated with a C5 inhibitor experience clinically significant EVH, which results in continued symptoms of anaemia and may require blood transfusions.
ALPHA
ALPHA is a pivotal, global Phase III trial designed as a superiority study to evaluate the efficacy and safety of Voydeya as an add-on to C5 inhibitor therapy Soliris or Ultomiris in patients with PNH who experience clinically significant EVH. In the double-blind, placebo-controlled, multiple-dose trial, patients were enrolled and randomised to receive Voydeya or placebo (2:1) in addition to their ongoing Soliris or Ultomiris therapy for 12 weeks. A prespecified interim analysis was performed once 63 randomised patients had completed 12 weeks of the primary evaluation period or discontinued treatment as of
Voydeya (danicopan)
Voydeya (danicopan) is a first-in-class, oral, Factor D inhibitor. The medication works by selectively inhibiting Factor D, a complement system protein that plays a key role in the amplification of the complement system response. When activated in an uncontrolled manner, the complement cascade over-responds, leading the body to attack its own healthy cells. Voydeya has been granted Breakthrough Therapy designation by the
Voydeya is approved in the US, EU and
Alexion is also evaluating Voydeya as a potential monotherapy for geographic atrophy in a Phase II clinical trial.
