About Us

 

Led by a team with vast experience in biopharmaceuticals, toxicology, botany, and emergency medicine, ToxEM LLC is a pharmaceutical company committed to the development of drugs derived from botanical sources that target life-threatening illnesses with high impact to the public health. 

 

ToxEM seeks to capitalize on the opportunity created by the FDA upon issuance of its Guidance for Industry-Botanical Drug Products which seeks to encourage and clarify the development of new therapies from botanical sources.  

 

ToxEM’s first drug product (TXM-24631) targets a complex bleeding disorder, disseminated intravascular coagulopathy (DIC), a life-threatening by-product of sepsis and a complication associated with a number of other acute diseases.  The main feature of DIC is abnormal release of thrombin which leads to rampant clotting until clotting factors are consumed. The result is unchecked bleeding.  DIC complicates up to 60 % of cases of severe sepsis, which is a significant cause of mortality in the United States, and globally.  Once contracted, DIC increases mortality by up to 40%. Hence, an effective treatment for DIC in sepsis should significantly decrease death rate from sepsis, especially if given early in treatment. ToxEM’s product acts as an anti-coagulant (antithrombotic) to prevent the abnormal clotting that characterizes DIC. DIC complicates other diseases with high impact to public health such as trauma, especially traumatic brain injury, and neoplasms. Moreover, its anti-coagulant activity suggests potential follow-on indications for thromboembolic diseases such as stroke, acute coronary syndromes, pulmonary embolism, and deep vein thrombosis.


      The Team

Mary E. Palmer, MD – Founder and Board Member

Dr Palmer is broadly experienced in botany, emergency medicine, toxicology and environmental conservation with particular focus on research and education. While Assistant Endangered Species Botanist for NC Department of Agriculture, she initiated the first comprehensive review of stewardship methods to monitor endangered plant populations on selected conservation lands in the US. As Director/Research Botanist for the Model Virginia Heritage Program for The Nature Conservancy (TNC), she successfully ushered the program into permanency into VA state government. In medicine she transferred her research interests into promotion of evidence-based clinical standards through co-Chairing the Practice Guidelines Committee of American Academy of Emergency Medicine (AAEM) as well as by organizing international (Iceland 2002) and national educational conferences at The George Washington University in 2004 and 2005. Blending botany, medicine and toxicology, Dr. Palmer has authored publications on plant toxicity including a multi-center study of adverse events associated with dietary supplements which was published in The Lancet. Dr. Palmer earned a BA from Kenyon College, an MS from The University of Virginia, her MD from The George Washington University before completing her residency in EM at the Medical College of Pennsylvania in Philadelphia and fellowship training in Medical Toxicology at the NYC Poison Control Center associated with NYU/Belleview Medical Centers.  Dr. Palmer currently practices EM part-time in the Washington metropolitan area.

 

Stephen N. Kirnon, Ed.D. – Business Advisor and Board Member
