Santarus, Inc. (NASDAQ: SNTS) and VeroScience, LLC today announced publication of positive data from a double-blind, placebo-controlled, multi-center pivotal study with CYCLOSET® (bromocriptine mesylate) tablets. Patient groups in the evaluable per protocol (EPP) population that added CYCLOSET to their treatment regimen achieved a 0.60% to 0.70% reduction in HbA1c (p<0.0001) relative to placebo after 24 weeks, the primary endpoint of the study. These results appear in the November/December 2012 print edition of Endocrine Practice, a peer-reviewed medical journal.
Additionally, among the EPP population with no concomitant change in diabetes medication, treatment with CYCLOSET resulted in:
CYCLOSET is a unique, quick release form of bromocriptine, a dopamine receptor agonist that is approved as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus. The study included 515 patients with type 2 diabetes with baseline HbA1c of =7.5% and =10.0% (average baseline HbA1c: 8.3) taking one or two oral anti-diabetes medications (metformin, sulfonylurea and/or thiazolidinediones). These poorly controlled patients were randomized 2:1 to CYCLOSET add-on (1.6 mg/day to 4.8 mg/day) or placebo add-on for a 24-week treatment period. Study investigators were allowed to adjust patient anti-diabetes medications during the study to attempt to achieve glycemic control in case of glycemic deterioration. The impact of CYCLOSET treatment was assessed in patients taking: (1) one or two oral anti-diabetes medications, (2) metformin with or without another oral anti-diabetes medication, or (3) metformin plus a sulfonylurea. The study was conducted in a cohort of patients imbedded in a larger randomized safety study.
The results of the primary endpoint analysis for the intent-to-treat (ITT) and EPP populations are summarized in the table below.

The most frequent adverse events in the study for CYCLOSET and placebo were, respectively, nausea (33% vs. 6%), fatigue (11% vs. 8%), dizziness (14% vs. 11%), headache (12% vs. 8%), constipation (7% vs. 3%), back pain (6% vs. 3%) and vomiting (6% vs. 2%). The discontinuation rate due to any adverse event was 20% for CYCLOSET-treated and 9% for placebo-treated patients.
“The results of this pivotal study show that the addition of CYCLOSET to the treatment regimen in this poorly controlled type 2 diabetes patient population produces significant and clinically relevant improvements in glycemic control markedly increasing the percent of patients reaching the HbA1c goal of = 7.0 vs. placebo,” stated Aaron I. Vinik, M.D., Ph.D, Strelitz Diabetes Center and Neuroendocrine Unit, Norfolk, Virginia and lead author of the paper.
