DISCOVER THE EFFICACY OF CYCLOSET®1

Proven HbA1c reduction when added glycemic control is needed1

Complementary efficacy of CYCLOSET® in clinical studies1

HbA1c=hemoglobin A1C.
*Study Design (CYCLOSET® Monotherapy): A 24-week, multicenter, double-blind, placebo-controlled study. CYCLOSET® monotherapy, n=80; placebo, n=79. At baseline and Week 24, patients received standardized meals at 7 AM (breakfast), 12 PM (lunch), and 5 PM (dinner). Blood samples were taken prior to and 1 and 2 hours following each meal and analyzed for insulin and glucose concentrations. Premeal plasma glucose levels at Week 24: fasting: CYCLOSET®=-2 mg/dL, placebo=+28 mg/dL; lunch: CYCLOSET®=-16 mg/dL, placebo=+15 mg/dL; dinner: CYCLOSET®=-2 mg/dL, placebo=+13 mg/dL.1-3
Study Design (CYCLOSET® + Sulfonylurea): Two 24-week, multicenter, placebo-controlled, double-blind studies. The primary endpoint was reduction in HbA1c relative to placebo. Study K: CYCLOSET®, n=114; placebo, n=122. Study L: CYCLOSET®, n=114; placebo, n=123. Intent-to-treat population using last observation carried forward between-group change from baseline in HbA1c.1,3
sup>‡Study Design (CYCLOSET® + 1-2 OADs): A 52-week, randomized, double-blind, multicenter, placebo-controlled safety study with subgroup efficacy assessments at Week 24. CYCLOSET® or placebo + 1 or 2 OAD medications, n=376; placebo, n=183. CYCLOSET® + metformin + sulfonylurea, n=177; placebo, n=90. CYCLOSET® + thiazolidinedione (TZD) +/- OAD, n=78; placebo, n=44. Patients in the “metformin + sulfonylurea” and “TZD +/- OAD” subgroups were also counted in the “adjunct to 1 to 2 OAD” subgroup. OADs included metformin, sulfonylurea, alpha-glucosidase inhibitor, meglitinide, phenylalanine derivative, or oral combination therapy formulated as 1 pill. Doses of background antidiabetic medications could be adjusted at any time during the trial, and additional antidiabetic medications were permitted after Week 12, if needed to maintain ideal glycemic control.1,2,4-6

In a pharmacodynamic study:

The CNS-acting insulin sensitizer helped reduce postprandial plasma glucose (PPG)1

The once-daily dose of CYCLOSET®, taken within 2 hours of waking, reduced PPG at 1 and 2 hours after each meal. CYCLOSET® helped reduce fasting and postprandial hyperglycemia throughout the meals of the day—without raising plasma insulin levels.1

CYCLOSET® was associated with improved insulin-mediated glucose disposal and glucose tolerance, which resulted in lower plasma glucose levels.1

§Study Design: Patients with type 2 diabetes mellitus (T2DM) on diet therapy alone and with poor glycemic control were randomized to treatment with CYCLOSET® or placebo (baseline fasting plasma glucose: 214 ± 6 and 203 ± 6 mg/dL; HbA1c: 9.0 ± 0.1 and 8.8 ± 0.1, respectively) and administered standardized meals at breakfast, lunch, and dinner, before and 24 weeks following treatment. Plasma samples taken before and 1 and 2 hours after each meal were analyzed for glucose and insulin.3
||A 2-way repeated-measures (ANOVA) analysis of treatment and hour indicate a significant treatment effect over the entire diurnal (7 AM to 7 PM) period (P=0.0012). The change from baseline in 2-hour glucose level is significantly different for CYCLOSET® vs placebo at all 3 meals (P<0.05). The improvements on diurnal and postprandial glucose were not associated with an increase in insulin level measured at any of these test times.3

IMPORTANT SAFETY INFORMATION

Contraindications

CYCLOSET is contraindicated in:

  • Patients with hypersensitivity to ergot-related drugs, bromocriptine or to any of the excipients in CYCLOSET.
  • Patients with syncopal migraines. May precipitate hypotension.
  • Postpartum patients. Serious and life-threatening adverse reactions have been reported.
  • Lactating patients. CYCLOSET contains bromocriptine which inhibits lactation.

INDICATION

CYCLOSET® (bromocriptine mesylate) 0.8 mg tablets is a dopamine receptor agonist indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus.

LIMITATIONS OF USE

  • CYCLOSET should not be used to treat type 1 diabetes or diabetic ketoacidosis.
  • Limited efficacy data in combination with thiazolidinediones.
  • Efficacy has not been confirmed in combination with insulin.

IMPORTANT SAFETY INFORMATION

Contraindications

CYCLOSET is contraindicated in:

  • Patients with hypersensitivity to ergot-related drugs, bromocriptine or to any of the excipients in CYCLOSET.
  • Patients with syncopal migraines. May precipitate hypotension.
  • Postpartum patients. Serious and life-threatening adverse reactions have been reported.
  • Lactating patients. CYCLOSET contains bromocriptine which inhibits lactation.

Orthostatic Hypotension/Syncope

  • CYCLOSET can cause orthostatic hypotension and syncope, particularly upon initiation or dose escalation. Use caution in patients taking antihypertensive medications. Orthostatic vital signs should be assessed prior to initiation of CYCLOSET and periodically thereafter.
  • Advise patients during early treatment to avoid situations that could lead to injury if syncope were to occur, and to make slow postural changes.

Psychotic Disorders

  • The use of CYCLOSET in patients with severe psychotic disorders is not recommended.

Impulse Control/Compulsive Behaviors

  • Consider dose reduction or discontinuation of CYCLOSET if a patient develops intense urges to gamble, increased sexual urges, intense urges to spend money uncontrollably and/or other intense urges.

Somnolence

  • CYCLOSET may cause somnolence, particularly when initiating therapy. Advise patients not to drive or operate heavy machinery if symptoms of somnolence occur.

Concomitant Use of Dopamine Antagonists or Agonists

  • Concomitant use with dopamine antagonists, such as neuroleptic agents, may diminish the effectiveness of both drugs and is not recommended.
  • Effectiveness and safety are unknown in patients already taking dopamine receptor agonists for other indications and concomitant use is not recommended.

Risks in Postpartum Patients

  • CYCLOSET is contraindicated in postpartum patients. Serious and life-threatening adverse reactions have been reported in postpartum women who were administered bromocriptine for inhibition of lactation. These risks may be higher in postpartum patients with cardiovascular disease. The indication for use of bromocriptine for inhibition of postpartum lactation was withdrawn from bromocriptine-containing products and is not approved for CYCLOSET.

Safety and Effectiveness in Pediatrics

  • The safety and effectiveness of CYCLOSET in pediatric patients have not been established.

Adverse Reactions

  • In clinical trials, the most common adverse reactions reported in ≥5% of patients treated with CYCLOSET, and reported more commonly than in patients treated with placebo, included nausea, fatigue, dizziness, vomiting, and headache. Postmarketing reports with higher doses of bromocriptine used for other indications include psychotic disorders, hallucinations, and fibrotic complications.

Drug Interactions

  • May increase the unbound fraction of highly protein-bound therapies, altering their effectiveness and safety profiles.
  • May increase ergot-related side effects or reduce ergot effectiveness for migraines if co-administered within 6 hours of ergot-related drugs.
  • Extensively metabolized by CYP3A4. Limit CYCLOSET dose to 1.6 mg/day during concomitant use of moderate CYP3A4 inhibitors. Avoid concomitant use of CYCLOSET with strong CYP3A4 inhibitors.
