3. From 1999 to 2007, the NIH awarded Dr. Xiao more than 2.4 million dollars for the clinical trial in SCI at New York University (NYU) [8]. It was said that 40 SCI patients had been involved with an 80% response rate [9], but so far no official results have been released, except for a conference abstract [10] that reported two cases with much worse urodynamic results than Dr. Xiao’s first 15 SCI patients in China [4]. Nevertheless, NYU discontinued its clinical study after running out of the multi-million dollar funding after several years of extension.

13 Patienten wurden bisher in den USA versorgt und wiesen eine deutlich schnellere Regeneration der Blasenfunktion von sechs Monaten auf, mit einer annahernd gleich bleibenden Erfolgswahrscheinlichkeit von 80 Prozent.

So far, 13 patients had been treated in the U.S. and it showed a noticeably fast recovery of bladder function from six months, with an almost the same constant 80% success rate (as Dr. Xiao previously reported).
