XBiotech Discovers COVID-19 Candidate TherapyThe Company has Identified Highly Targeted Anti-COVID-19 True Human Antibodies from Immune Donor Blood
AUSTIN, Texas, Aug. 17, 2020 (GLOBE NEWSWIRE) -- xBiotech USA, Inc. (NASDAQ: XBIT) announced today that it has identified True Human antibodies that could potentially be used as a therapy against SARS-CoV2, the virus that causes COVID-19. The Company discovered these antibodies through a collaboration with BioBridge Global (parent organization of the South Texas Blood & Tissue Center and QualTex Laboratories, one of the largest independent testing laboratories in the United States).
For the collaboration, BioBridge Global used XBiotech’s proprietary COVID-19 screening technology to identify blood donors who had been infected by the novel coronavirus, as part of a program to provide convalescent plasma to treat patients suffering from severe COVID-19 infections. In return, BioBridge Global provided XBiotech with blood samples from patients who had been infected with COVID-19. For its antibody discovery process, XBiotech selected blood samples from patients who had recovered rapidly from the virus without serious illness—factors that indicated these donors had antibodies that were highly effective at protecting them against the virus.
It was only May 21, 2020 that XBiotech received its donor blood and launched its discovery program for COVID-19 True Human antibodies. Today, XBiotech now has a number of True Human antibodies that precisely block the COVID-19 virus’ ability to be infectious and at the same time enable the body to naturally clear the virus.
Dr. Galina Kuzmicheva, Ph.D., XBiotech’s Principal Scientist who led the COVID-19 discovery effort, commented, “COVID-19 has resulted in an unprecedented impact on our community. We are pleased to be able to utilize our unique discovery technology to rapidly identify natural human immunity—in the form of True Human antibodies—that can potentially be used to treat the virus infection in humans.”
XBiotech is a fully integrated, global biopharmaceutical company dedicated to pioneering the discovery, development and commercialization of therapeutic antibodies. XBiotech currently is advancing a pipeline of therapies by harnessing naturally occurring antibodies from patients with immunity to certain diseases. Utilizing natural human immunity as a source of new medicines offers the potential to redefine the standards of care for a wide range of diseases.
On December 30, 2019 XBiotech sold an IL-1⍺ blocking True Human™ antibody that had been used successfully in a number of clinical trials. The sale of the antibody generated $750 million in upfront cash and up to $600 million in potential milestone payments. The Company retained the right to pursue the development of True Human™ antibodies targeting IL-1⍺ for all areas of medicine outside of dermatology. While the Company previously was focused on a single True Human™ antibody targeting IL-1⍺, it now plans to develop multiple product candidates, which will target IL-1⍺ in specific areas of medicine.
In addition to recent sale of its anti-IL-1⍺ antibody, XBiotech now has other revenue sources. Commencing January 1, 2020 XBiotech began using its proprietary manufacturing technology to produce clinical drug product for a major Pharmaceutical Company under a two-year supply agreement. In addition, XBiotech is providing clinical trial contract research operations to conduct two large, double-blind placebo-controlled Phase II clinical studies. The financial strength generated from the sale and contract operations is enabling XBiotech to expand both its anti-IL-1⍺ product development and infectious disease programs.
To accelerate advance of the Company’s pipeline, the Company is expanding its existing manufacturing and research center, and planning to build an additional 30,000ft2 infectious disease research & development center on its 48-acre property in Austin, TX which is wholly owned by the Company. The expansion and new building will be in addition to the present custom-built 33,000ft2 combined manufacturing and R&D facility that currently exists on the campus. XBiotech owns the 48-acre campus—and all structures on the property—debt-free and envisions further expansion of facilities. For more information, visit www.xbiotech.com.
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.
