Outcomes
Primary outcome [1] 333947 0
Safety and tolerability of GLX-100 by measuring the incidence and severity of adverse events. Examples for possible adverse events include urinary tract infections and urinary urgency that will be assessed according to standard clinical practice. Medical notes will be used to collect adverse event data.
