Grifols is working with various government health authorities, plasma donation centers, research institutes, universities and hospitals across the world on multiple international clinical trials.

Potential Therapy with
Anti-SARS-CoV-2 Hyperimmune Globulin

Clinical trials with Grifols' anti-SARS-CoV-2 hyperimmune globulin are being developed through a formal collaboration with the U.S. Food and Drug Administration (FDA), the National Institutes of Health (NIH) and the Biomedical Advanced Research Development Authority (BARDA).

One month after beginning production of the anti-SARS-CoV-2 hyperimmune globulin Grifols delivered the first manufactured batches for clinical trials developed in our plant in Clayton, North Carolina. Recently, the FDA has approved the protocol to start the clinical trial that will evaluate its safety and efficacy.

The anti-SARS-CoV-2 hyperimmune globulin, which is derived from the blood plasma of healthy donors recovered from COVID-19, is a highly specific, pure and safe medicine that delivers a high and consistent concentration of protective antibodies that if proven effective could be used for the prevention and treatment of the disease.

Moving decisively against

Grifols has over 100 years of extensive experience in the research, development and successful application of plasma-derived therapies, including hyperimmune globulins for the prevention and treatment of well-known diseases such as rabies and tetanus.

Anti-SARS-CoV-2 Hyperimmune Globulin

Plasma from recovered COVID-19 donors can be converted into a potential treatment containing high and consistent concentrations of antibodies.

Potential Therapy with Convalescent Plasma for Direct Transfusion

In addition to the hyperimmune globulin, Grifols is currently conducting several clinical trials in collaboration with health regulatory agencies, both in Europe and the U.S., selected blood banks, transfusion centers and public hospitals. The aim of these trials is to study the safety and efficacy of plasma from recovered COVID-19 donors that has been virally inactivated with methylene blue.

Convalescent plasma was approved for emergency use by the FDA on August 23 to treat hospitalized patients with COVID-19.

Methylene blue inactivation

Direct transfusion of convalescent plasma to COVID-19 patients might help treat the disease. Before transfusion, the convalescent plasma is pathogen-inactivated with methylene blue technology to ensure safety.

Potential Therapies with Other Existing Plasma-derived Medicines 

Grifols is currently collaborating with a range of different experts, academics, hospitals and researchers across both the U.S. and Europe to evaluate the efficacy of other existing
plasma-derived medicines for the treatment of patients with COVID-19.

These products range from existing intravenous immunoglobulin to alpha-1 antitrypsin.

Everything starts with donations

If you have recovered from COVID-19 and would like to donate plasma and help fight the pandemic, please consider giving your plasma at a donation center or blood bank near you.

Now more than ever, we are extremely grateful to those who donate.

Grifols is proud to be part of a coalition of world-class medical and research institutions, blood centers, life-science companies, philanthropic organizations and COVID-19 survivor groups that has come together to mobilize tens of thousands of people in the United States who have recovered from COVID-19 to donate their plasma, which contains essential antibodies that have fought off the disease and could help others do the same.
