*To provide a complete accounting of the 6139 randomized patients, this table includes data from patients after they received glycemic rescue therapy, whereas the primary safety analysis focuses on results excluding data after patients received rescue therapy. These numbers include patients discontinued over periods of up to 2 years, including those patients who underwent glycemic rescue during the placebo-controlled phase and were ineligible in some studies to enter into the continuation phase.

Includes patients not meeting the progressively stricter, protocol-specified, glycemic rescue criteria and/or not meeting the investigator's expectations of glycemic improvement.
