"When will the renal trial start recruiting/enrolling patients?"
Clayton let me know that the anticipated study start date of June 15th, 2017 originally listed on ClinicalTrials.gov has been changed to September 15, 2017. Looks like there was an update to ClinicalTrials.gov on July 5th. Well, there goes one potential news release before the end of August.
