Lumena’s lead candidate, LUM001, has been extensively evaluated in other indications across 12 clinical studies in more than 1,400 subjects.

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.
