Medicine should make you feel better, not worse

Modern medicine should help patients feel better, not worse. At XBiotech, we believe in the Hippocratic principle of "do no harm." We believe this is inherent to the innovative True Human™ antibody medicines we are developing. True Human™ antibodies move beyond the idea that effective medicines must come with toxicity or harmful side effects.

 

By utilizing the body’s natural immune system, XBiotech develops therapies that help you heal and feel better.

XBiotech’s True Human™ antibodies are derived from individuals with natural immunity to disease.
