Baxalta Submits Marketing Authorization Application To The European Medicines Agency For ADYNOVI For Treatment Of Hemophilia A Patients

BANNOCKBURN, Ill.--(BUSINESS WIRE)--Baxalta Incorporated (NYSE:BXLT), a global biopharmaceutical leader dedicated to delivering transformative therapies to patients with orphan diseases and underserved conditions, today announced that it has submitted a Marketing Authorization Application (MAA) to the European Medicines Agency (EMA) for approval of ADYNOVI, an extended circulating half-life recombinant Factor VIII (rFVIII) treatment, for pediatric, adolescent and adult patients with hemophilia A and for use during surgery. Currently licensed in the U.S. as ADYNOVATE [Antihemophilic Factor (Recombinant), PEGylated] and under regulatory review in Japan, Canada and Switzerland, ADYNOVI is the only rFVIII treatment for hemophilia A developed based on the demonstrated efficacy of ADVATE [Antihemophilic Factor (Recombinant)].

''We are dedicated to bringing ADYNOVI to hemophilia A patients all over the world,’' said Brian Goff, executive vice president and president, Hematology, Baxalta. ''As we build on our market-leading portfolio of direct factor replacement treatments, we continually bring new options to hemophilia patients, empowering them to manage their hemophilia, with their caregivers, in the way that works best for them.’'

ADYNOVI was studied in patients, 12 to 65 years of age, in a prospective, global, multi-center, open label, non-randomized study; in patients 12 years of age and younger, in a prospective, uncontrolled, open-label, multi-center study; and for the perioperative control of hemostasis among 15 patients with severe hemophilia A undergoing surgical procedures. The EMA filing is based on data from these three Phase 3 clinical trials, which Baxalta shared publicly in December 2015.

Hemophilia A is a challenging chronic disease; treatment regimens require regular infusions to reduce the risk of bleeding. Working closely with their health professionals, many patients continue to seek treatment options that can be better personalized to fit their needs, providing both effective bleed protection and simplified dosing schedules. Today, hemophilia affects more than 400,000 people globally and an estimated 75 percent of people with hemophilia are inadequately treated.¹ Baxalta continues to innovate in order to address some of the greatest challenges associated with hematologic disorders, including hemophilia.

About ADYNOVATE in the United States

ADYNOVATE is built on the full-length ADVATE molecule, a leading treatment for hemophilia A that been used by patients worldwide for more than 12 years. Through a collaboration with Nektar Therapeutics (NASDAQ: NKTR), ADYNOVATE leverages proprietary PEGylation technology designed to extend the amount of FVIII available for use in the body. The technology was selected because it maintains the integrity of the parent molecule (ADVATE) and reduces the time at which the body clears ADYNOVATE, resulting in an extended circulating half-life. This proprietary technology has been used for more than 15 years in a number of approved medicines that treat chronic or serious conditions.

Indications:

In the United States, ADYNOVATE, [Antihemophilic Factor (Recombinant), PEGylated], is a human antihemophilic factor indicated in adolescent and adult patients (12 years and older) with hemophilia A (congenital factor VIII deficiency) for:

• On-demand treatment and control of bleeding episodes
• Routine prophylaxis to reduce the frequency of bleeding episodes

ADYNOVATE is not indicated for the treatment of von Willebrand disease.

Detailed Important Risk Information

CONTRAINDICATIONS

ADYNOVATE is contraindicated in patients who have had prior anaphylactic reaction to ADYNOVATE, to the parent molecule (ADVATE), mouse or hamster protein, or excipients of ADYNOVATE (e.g. Tris, mannitol, trehalose, glutathione, and/or polysorbate 80).

WARNINGS & PRECAUTIONS

Hypersensitivity Reactions

Hypersensitivity reactions are possible with ADYNOVATE. Allergic-type hypersensitivity reactions, including anaphylaxis, have been reported with other recombinant antihemophilic factor VIII products, including the parent molecule, ADVATE. Early signs of hypersensitivity reactions that can progress to anaphylaxis may include angioedema, chest tightness, dyspnea, wheezing, urticaria, and pruritus. Immediately discontinue administration and initiate appropriate treatment if hypersensitivity reactions occur.

Neutralizing Antibodies

Formation of neutralizing antibodies (inhibitors) to factor VIII can occur following administration of ADYNOVATE. Monitor patients regularly for the development of factor VIII inhibitors by appropriate clinical observations and laboratory tests. Perform an assay that measures factor VIII inhibitor concentration if the plasma factor VIII level fails to increase as expected, or if bleeding is not controlled with expected dose.

ADVERSE REACTIONS

Common adverse reactions (=1% of subjects) reported in the clinical studies were headache and nausea.

About ADVATE in the United States

ADVATE has a demonstrated efficacy and safety profile for the treatment of hemophilia A. ADVATE is a full-length (derived from the complete FVIII gene) recombinant FVIII product that is processed without any blood-based additives. Because no blood-derived components are added at any stage of the manufacturing process, the potential risk of transmitting pathogens that may be carried in blood-based additives is virtually eliminated. There have been no confirmed reports of transmission of HIV, HBV or HCV with rFVIII treatments.

ADVATE is the world’s most prescribed FVIII treatment. It is currently approved in 67 countries worldwide, including the United States, Canada, 28 countries in the European Union, Algeria, Argentina, Australia, Brazil, Brunei, Chile, China, Colombia, Ecuador, Hong Kong, Iceland, India, Iraq, Israel, Japan, Kuwait, Macau, Malaysia, Mexico, Morocco, New Zealand, Norway, Panama, Puerto Rico, Qatar, Russia, Saudi Arabia, Serbia, Singapore, South Korea, Suriname, Switzerland, Taiwan, Tunisia, Turkey, Ukraine, Uruguay, and Venezuela.

Indications:

ADVATE [Antihemophilic Factor (Recombinant)] is a recombinant antihemophilic factor indicated for use in children and adults with hemophilia A (congenital factor VIII deficiency) for:

• Control and prevention of bleeding episodes
• Perioperative management
• Routine prophylaxis to prevent or reduce the frequency of bleeding episodes

ADVATE is not indicated for the treatment of von Willebrand disease.

Detailed Important Risk Information

CONTRAINDICATIONS

ADVATE is contraindicated in patients who have life-threatening hypersensitivity reactions, including anaphylaxis, to mouse or hamster protein or other constituents of the product.

WARNINGS & PRECAUTIONS

Hypersensitivity Reactions

Allergic-type hypersensitivity reactions, including anaphylaxis, have been reported with ADVATE. Symptoms include dizziness, paresthesia, rash, flushing, facial swelling, urticaria, dyspnea, pruritus, and vomiting.

Discontinue ADVATE if hypersensitivity symptoms occur and administer appropriate emergency treatment.

Neutralizing Antibodies

Neutralizing antibodies (inhibitors) have been reported following administration of ADVATE predominantly in previously untreated patients (PUPs) and previously minimally treated patients (MTPs). Monitor all patients for the development of factor VIII inhibitors by appropriate clinical observation and laboratory testing. If expected plasma factor VIII activity levels are not attained, or if bleeding is not controlled with an expected dose, perform an assay that measures factor VIII inhibitor concentration.

ADVERSE REACTIONS

Serious adverse reactions seen with ADVATE are hypersensitivity reactions, including anaphylaxis, and the development of high-titer inhibitors necessitating alternative treatments to factor VIII.

The most common adverse reactions observed in clinical trials (frequency =5% of subjects) were pyrexia, headache, cough, nasopharyngitis, arthralgia, vomiting, upper respiratory tract infection, limb injury, nasal congestion, and diarrhea.
