Approval of first-in-class, oral, Factor D inhibitor based on results from pivotal ALPHA Phase III trial

VOYDEYA™ (danicopan) has been approved in the US as add-on therapy to ravulizumab or eculizumab for the treatment of extravascular hemolysis (EVH) in adults with paroxysmal nocturnal hemoglobinuria (PNH).¹ VOYDEYA is a first-in-class, oral, Factor D inhibitor developed as an add-on to standard-of-care ULTOMIRIS^® (ravulizumab-cwvz) or SOLIRIS^® (eculizumab) to address the needs of the approximately 10-20% of patients with PNH who experience clinically significant EVH while treated with a C5 inhibitor.^2,3

The approval by the US Food and Drug Administration (FDA) was based on positive results from the pivotal ALPHA Phase III trial. Results from the 12-week primary evaluation period of the trial were published in The Lancet Haematology.²

Bart Scott, MD, Professor, Division of Hematology and Oncology at the University of Washington Medical Center, and Professor, Clinical Research Division at Fred Hutchinson Cancer Center, said: “The approval of VOYDEYA offers this small subset of PNH patients an add-on therapy designed to address EVH, while maintaining disease control with ULTOMIRIS or SOLIRIS. Terminal complement inhibition with ULTOMIRIS can address the life-threatening complications of PNH, building on the efficacy and safety of SOLIRIS established over nearly 20 years.”

Marc Dunoyer, Chief Executive Officer, Alexion, said: “The approval of first-in-class, Factor D inhibitor VOYDEYA marks an important advancement in the treatment of PNH and builds on our leadership and commitment to bring forward innovation in complement science. As the ALPHA trial suggests, dual complement pathway inhibition at Factor D and C5 may be an optimal treatment approach for this subset of patients with EVH, enabling them to continue with proven standard-of-care therapy.”

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 hemoglobin 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 diarrhea.²

VOYDEYA has been granted Breakthrough Therapy designation by the US FDA and PRIority MEdicines (PRIME) status by the European Medicines Agency. VOYDEYA has also been granted Orphan Drug Designation in the US, European Union (EU) and Japan for the treatment of PNH. VOYDEYA has been approved in Japan and recommended for approval in the EU. Regulatory reviews are ongoing in additional countries.

Notes

PNH

PNH is a rare, chronic, progressive and potentially life-threatening blood disorder. It is characterized by red blood cell destruction within blood vessels (also known as intravascular hemolysis) and white blood cell and platelet activation, which can result in thrombosis (blood clots).^4-6

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 defense 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, anemia and dark-colored urine.^4,7,8

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 anemia, 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 anemia and may require blood transfusions.^4,7,14,15

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 randomized 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 randomized patients had completed 12 weeks of the primary evaluation period or discontinued treatment as of June 28, 2022. At 12 weeks, patients on placebo plus SOLIRIS or ULTOMIRIS were switched to VOYDEYA plus SOLIRIS or ULTOMIRIS, and patients on VOYDEYA plus SOLIRIS or ULTOMIRIS remained on this treatment for an additional 12 weeks. Patients who completed both treatment periods (24 weeks) had the option to participate in a two-year long-term extension period and continue to receive VOYDEYA in addition to SOLIRIS or ULTOMIRIS. The open-label period of the study is ongoing.^2,16

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 US Food and Drug Administration and PRIority MEdicines (PRIME) status by the European Medicines Agency. VOYDEYA has also been granted Orphan Drug Designation in the US, EU and Japan for the treatment of PNH.

VOYDEYA is approved in the US as add-on therapy to ravulizumab or eculizumab for the treatment of EVH in adults with PNH.

VOYDEYA is also approved in Japan for certain adults with PNH in combination with C5 inhibitor therapy.

Alexion is also evaluating VOYDEYA as a potential monotherapy for geographic atrophy in a Phase II clinical trial.

ULTOMIRIS^® (ravulizumab-cwvz)

ULTOMIRIS^® (ravulizumab-cwvz), the first and only long-acting C5 complement inhibitor, provides immediate, complete and sustained complement inhibition. The medication works by inhibiting the C5 protein in the terminal complement cascade, a part of the body’s immune system. When activated in an uncontrolled manner, the complement cascade over-responds, leading the body to attack its own healthy cells. ULTOMIRIS is administered intravenously every eight weeks in adult patients, following a loading dose.

ULTOMIRIS is approved in the US, EU, Japan and other countries for the treatment of certain adults with generalized myasthenia gravis (gMG).

ULTOMIRIS is also approved in the US, EU, Japan and other countries for the treatment of certain adults with PNH and for certain children with PNH in the US and EU.

Additionally, ULTOMIRIS is approved in the US, EU, Japan and other countries for certain adults and children with atypical hemolytic uremic syndrome to inhibit complement-mediated thrombotic microangiopathy (aHUS).

Further, ULTOMIRIS is approved in the US, EU and Japan for the treatment of certain adults with neuromyelitis optica spectrum disorder (NMOSD).

As part of a broad development program, ULTOMIRIS is being assessed for the treatment of additional hematology and neurology indications.

SOLIRIS^® (eculizumab)

SOLIRIS^® (eculizumab) is a first-in-class C5 complement inhibitor. The medication works by inhibiting the C5 protein in the terminal complement cascade, a part of the body’s immune system. When activated in an uncontrolled manner, the terminal complement cascade over-responds, leading the body to attack its own healthy cells. SOLIRIS is administered intravenously every two weeks, following an introductory dosing period.

SOLIRIS is approved in the US, EU, Japan, China and other countries for the treatment of patients with PNH and aHUS.

Additionally, SOLIRIS is approved in Japan and the EU for the treatment of certain adult and pediatric patients with gMG, and in the US, China and other countries for certain adults with gMG.

Further, SOLIRIS is approved in the US, EU, Japan, China and other countries for the treatment of certain adults with NMOSD.

SOLIRIS is not indicated for the treatment of patients with Shiga-toxin E. coli-related hemolytic uremic syndrome.
