XBiotech-Developed COVID-19 Test Supports Convalescent Blood Treatments Now Approved Under FDA Emergency Use Authorization
FDA has Authorized Use of Antibody-Rich COVID-19 Therapy Derived from Convalescent Patients
Under Collaboration BioBridge Global Will Be Using XBiotech’s COVID-19 Antibody Test to Identify the Convalescent Blood Products
While XBiotech’s testing technology will be used as the first step in the production of anti-COVID-19 convalescent blood products, XBiotech (XBIT) has also used the convalescent blood samples supplied by BioBridge to identify the precise genetic information present in individuals producing these natural antibodies against COVID-19. The Company recently announced it had in fact successfully discovered candidate True Human therapeutic antibodies based on this effort.
The decision by the FDA to approve use of convalescent plasma (or blood with natural anti-COVD-19 antibodies from patients that recovered from the infection) comes from the Agency’s extensive review of scientific data developed over the past several months. These preliminary findings show that convalescent plasma is safe and effective in treating COVID-19, such that a 35% better survival rate has been observed in patients 30 days after receiving plasma treatment. Furthermore, there have been approximately 70,000 patients treated to date with no concerning safety signals.
This data strongly supports XBiotech’s approach and technology for identifying therapeutic antibodies—which it does for a variety of diseases—from convalescent blood. By identifying and manufacturing the actual antibodies from convalescent patients, the Company is able to produce candidate drug products with highly concentrated purified antibody. This approach allows the Company to harness the body’s immune response to the virus and make targeted therapies that could potentially be safe and effective.

About True Human™ Therapeutic Antibodies
XBiotech’s True Human™ antibodies are the only available antibodies derived without modification from humans who possess natural immunity to certain diseases. (Unlike all commercially available antibodies, which are called “Humanized” or “Fully Human,” XBiotech’s True Human™ antibodies are directly sourced from the natural human immune response for specific diseases without modification.) XBiotech’s True Human antibodies have the potential to harness the body’s natural immunity to fight disease with unprecedented safety, efficacy, and tolerability.
