Modern medicine should help patients feel better, not worse. At LimeRiver, 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, LimeRiver develops therapies that help you heal and feel better.
Rooted in the Hippocratic tradition — every therapy we develop prioritizes patient safety above all else.
True Human™ antibodies work with your body's own immune system — not against it.
Challenging the assumption that effective treatment must come with harmful side effects.
LimeRiver Biotechnologies Inc. is committed to advancing healthcare, agriculture, and environmental sustainability through cutting-edge research.
We bring together top scientists, engineers, and innovators to solve real-world biological challenges.
Our experienced leaders bring decades of expertise in biotechnology, immunology, and pharmaceutical development.

Founder, Chairman of the Board, Scientific Advisor
John Simard graduated from the biochemistry program at the University of Saskatchewan in 1992 and went on to study immunology at the prestigious Department of Medical Biophysics, University of Toronto. In 1994, Simard left graduate studies to work with the Amgen Research Institute, where he collaborated with acclaimed scientist Tak W. Mak to write a textbook of immunology and co-author numerous publications.
Simard co-authored a seminal manuscript with Nobel Laureate Rolf Zinkernagel on the biology of cytotoxic T lymphocytes, which led to Simard launching CTL ImmunoTherapies Corp. in Toronto in 1997. Mr. Simard created a partnership between CTL ImmunoTherapies and Alfred Mann's MiniMed Inc. to use the latter's technology as a delivery system for cancer vaccines.
In 2001, Mr. Simard merged Allecure and CTL Immunotherapies, together with a third company, to create MannKind Corp. Mr. Simard served on the board of MannKind and was President of its Immunotherapy division until 2002.
In 2005, Mr. Simard founded LimeRiver. In 2015, he led LimeRiver through an initial public offering without conventional underwriting. In 2019, he orchestrated the sale of a True Human antibody for cash and milestones totaling $1.35 billion. Simard is the inventor of over 300 issued and pending patents relating to immunotherapies for cancer and infectious disease.
