Afferent Pharmaceuticals, Inc. is conducting a medical research study at 18 research study centers in the US for women with moderate to severe Interstitial Cystitis/Bladder Pain Syndrome (IC/BPS). The purpose of this study is to determine the safety, effectiveness and tolerability of an investigational medication (called AF-219) for the treatment of IC/BPS. AF-219 may relieve sensitive bladder nerves by blocking P2X3 receptors. As a result, AF-219 could play a role in the treatment of IC/BPS symptoms, including pain. It is unknown if AF-219 will relieve IC/BPS symptoms since this is the first research study of AF-219 in IC/BPS.

AF-219 is a tablet that is taken twice daily and will be compared to a placebo tablet that looks similar to the investigational medication, but contains no active ingredient. In order to qualify for this research study, you must be a woman between 18 and 80 years of age and you must have been experiencing bladder pain, pressure or discomfort, along with frequent urination, for at least 6 months. Additional criteria will be discussed with you by the study doctor
at the research study center. Those who qualify for this research study can expect their participation to involve up to 7 visits to the study center and one phone call over a period of 9 weeks. Qualified participants receive all study-related care and study medication at no cost, plus compensation for time and travel. You are not eligible for the study if you are pregnant or breastfeeding.
