FDA approval of genetic test for alpha-1 deficiency and EMA approval of fibrin sealant

Barcelona, November 17, 2017.- Grifols (MCE:GRF, MCE:GRF.P NASDAQ:GRFS) has received approval by the U.S. Food and Drug Administration (FDA) for a new genetic test to detect alpha-1 antitrypsin deficiency. The authorization marks an important milestone in the industry as it is the first time the FDA has approved a biological molecular test that uses the DNA of the patient for the diagnostic.

The FDA has approved the test for both DNA extracted from blood, as well as a drop of blood collected on paper (dry blood spot). A1AT Genotyping Test, developed by Progenika Biopharma, a Grifols subsidiary headquartered in Bilbao (Spain) is capable of simultaneously analyzing 99% of the most prevalent known mutations causing alpha-1 antitrypsin deficiency.

The molecular test analyzes simultaneously 192 samples per kit, and in a single reaction, identifies 14 of the most prevalent known mutations in the SERPINA1 gene, responsible for this genetic disorder. Although highly complex, the test has been designed so any molecular biology laboratory can process it with minimal human intervention.

A1AT Genotyping Test also has the CE marking from December 2016.

Grifols, global leader in the production and sale of alpha-1 antitrypsin, focus its growth strategy for this plasma protein on improving the diagnosis of the alpha-1 antitrypsin deficiency.

Grifols' portfolio of products already includes a diagnostic test that measures the level of this protein in the bloodstream. With this latest FDA approval, Grifols further consolidates its strategy and adds a new diagnostic test to continue actively advancing the diagnosis of alpha-1 antitrypsin deficiency in the United States, Europe, and more recently in Latin America.

The FDA approval also reinforces Grifols' strategy of promoting synergies among its business lines through the development of complementary products and services for its divisions.

New Fibrin Biological Sealant

The European Commission, following a favorable recommendation from the European Medicines Agency's (EMA) Committee for Medicinal Products for Human Use (CHMP), has approved a new Grifols product, a fibrin sealant composed of two plasma proteins (human fibrinogen and thrombin) for surgical use in adult patients.

Grifols obtained FDA approval for this product on November 1, 2017.

The recent approval of the product by the European and U.S. health authorities culminates an important R&D effort for Grifols, allowing it to expand its offer of plasma-derived products. The biological sealant will be manufactured at the Grifols industrial complex located in Parets del Vallès (Barcelona, Spain).

Alpha-1 antitrypsin deficiency, an inherited and under-diagnosed disorder

Alpha-1 deficiency is an inherited disorder that causes a deficiency or absence of the
alpha-1 protein in the plasma. It has a higher prevalence than other rare lung diseases such as cystic fibrosis and pulmonary arterial hypertension. While AATD symptoms vary depending on the degree of severity and type of genetic mutation, the most common is a progressive loss of pulmonary function.

Alpha-1-antitrypsin deficiency affects an estimated 25 cases per 100,000 people¹, more than 90% of cases remain undiagnosed. In the U.S., approximately 100,000 people suffer from AATD, with similar numbers estimated in Europe. In Spain, roughly 10,000 to 12,000 people have alpha-1 antitrypsin deficiency.

Common symptoms of alpha-1 deficiency include dyspnea, or shortness of breath following physical exertion; chronic coughing; excessive mucous production; and wheezing, with or without the presence of respiratory infections. The symptomology of AATD concurs with that of chronic obstructive pulmonary disease (COPD), asthma, and other pulmonary diseases, leading many patients to be treated for other disorders while the root cause remains unaddressed.

Early diagnosis of AATD is vital. Without adequate treatment, patients are at risk for pulmonary emphysema, which can prove fatal without a lung transplant. AATD is also the most common cause of liver disease in children.
