Lumena Pharmaceuticals
San Diego, CA
Lumena Pharmaceuticals is a privately-held biotechnology company developing oral therapeutics for rare liver diseases to improve liver function, relieve disease symptoms and dramatically impact patient health.

Lumena’s lead candidate, LUM001, has been extensively evaluated in other indications across 12 clinical studies in more than 1,400 subjects. Because of the extensive preclinical and clinical data package, LUM001 is positioned to rapidly progress through the clinic in pediatric and adult patients with several types of cholestatic liver disease.

ZS Pharma, Inc.
Coppell, TX
ZS Pharma is a late-stage company developing a drug to treat Hyperkalemia. Hyperkalemia is a serious and potentially life-threating condition where one’s potassium levels become dangerously elevated causing arrhythmias and cardiac arrest. Hyperkalemia is most often seen in patients with chronic kidney disease (CKD) due to renal insufficiency and the condition is exacerbated by medications that these patients typically take (i.e. they increase serum potassium). In the U.S. alone there are approximately 25 million people with CKD and this number is expected to increase for the foreseeable future.
