Xenon's Epilepsy Candidate Rapidly Reduces Focal Onset Seizure Frequency

Last week, Rockwell Medical Inc RMTI closed the second $7.5-million tranche of the previously announced DaVita Inc DVA stock purchase agreement of up to $15 million in convertible preferred stock in two tranches. 

The planned Phase 2 proof of concept study design for ferric pyrophosphate citrate in home infusion patients for iron deficiency anemia and maintaining hemoglobin requires three units of the existing FDA-approved IV product to be compounded into a single unit for each patient dose.
