Study: Once-Weekly Trulicity™ (dulaglutide) Provides Greater Blood Sugar Reduction Compared to Once-Daily Victoza® (liraglutide) in Japanese Patients after 52 weeks
"These data not only reinforce once-weekly Trulicity as a safe and efficacious GLP-1 receptor agonist, but further support the value for Japanese patients, with greater A1C reductions compared to once-daily Victoza," said
The study's primary objective was met, with Trulicity 0.75 mg demonstrating a greater A1C reduction from baseline compared to placebo at 26 weeks. At the final endpoint of 52 weeks, which is the focus of the data presentation at the meeting, Trulicity 0.75 mg demonstrated statistically greater A1C reductions compared to Victoza 0.9 mg, the highest approved dose in
- Trulicity 0.75 mg provided statistically greater reductions in the average self-monitored blood glucose levels compared to Victoza 0.9 mg (-53.1 mg/dL vs. -46.8 mg/dL); and
- Trulicity 0.75 mg significantly lowered average post-meal blood glucose levels from baseline compared to Victoza 0.9 mg (-63.7 mg/dL vs. -55.4 mg/dL).1
Mean body weight did not change in either treatment group. 1
Both Trulicity and Victoza were well-tolerated in the study. No cases of adjudicated pancreatitis were reported, and no new safety signals were seen. The most frequently reported adverse events were gastrointestinal-related with Trulicity 0.75 mg and Victoza 0.9 mg, including:
- constipation (7.9 percent vs. 8 percent),
- diarrhea (7.1 percent vs. 4.4 percent),
- nausea (6.1 percent vs. 8 percent),
- abdominal distension (4.3 percent vs. 5.1 percent), and
- decreased appetite (0.7 percent vs. 5.8 percent). Reports of decreased appetite were significantly different between the two treatments.1
Total hypoglycemia incidence in both treatment groups was 2.9 percent, with no severe hypoglycemia reported.1

About the Study
This Phase 3, randomized, parallel-arm, placebo-controlled, 52-week study compared the safety and efficacy of once-weekly Trulicity 0.75 mg to once-daily Victoza 0.9 mg. The primary objective of the study, conducted in 487 Japanese patients with type 2 diabetes and an average baseline A1C of 8.1 percent, was to evaluate whether Trulicity 0.75 mg was superior to placebo in reducing A1C from baseline at 26 weeks. The study also included a comparison of Trulicity and Victoza at 26 and 52 weeks. Patients initially assigned to placebo were switched to Trulicity 0.75 mg at 26 weeks for the remainder of the trial. Victoza 0.9 mg is the highest approved dose in
Indication and Limitations of Use for Trulicity
Trulicity is indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes.
Trulicity is not recommended as first-line therapy for patients inadequately controlled on diet and exercise because of the uncertain relevance of rodent C-cell tumor findings to humans. Prescribe only if potential benefits outweigh potential risks. It has not been studied in patients with a history of pancreatitis and other antidiabetic therapies should be considered. Trulicity is not for the treatment of type 1 diabetes mellitus or diabetic ketoacidosis. Trulicity is not a substitute for insulin and has not been studied in combination with basal insulin. Trulicity has not been studied in patients with severe gastrointestinal disease, including severe gastroparesis, and is not for patients with pre-existing severe gastrointestinal disease.
Important Safety Information for Trulicity™
WARNING: RISK OF THYROID C-CELL TUMORS
Trulicity is contraindicated in patients with a personal or family history of MTC or in patients with MEN 2, and in patients with a prior serious hypersensitivity reaction to dulaglutide or any of the product components.
Risk of Thyroid C-cell Tumors: Cases of MTC in patients treated with liraglutide, another GLP-1 receptor agonist (GLP-1 RA), have been reported in the postmarketing period; the data in these reports are insufficient to establish or exclude a causal relationship between MTC and GLP-1 RA use in humans. If serum calcitonin is measured and found to be elevated or thyroid nodules are noted on physical examination or neck imaging, the patient should be further evaluated.
Pancreatitis: Has been reported in clinical trials. Observe patients for signs and symptoms including persistent severe abdominal pain. If pancreatitis is suspected, discontinue Trulicity promptly. Do not restart if pancreatitis is confirmed. Consider other antidiabetic therapies in patients with a history of pancreatitis.
Hypoglycemia: The risk of hypoglycemia is increased when Trulicity is used in combination with insulin secretagogues (e.g., sulfonylureas) or insulin. Patients may require a lower dose of the sulfonylurea or insulin to reduce the risk of hypoglycemia.
Hypersensitivity Reactions: Systemic reactions were observed in patients receiving Trulicity in clinical trials. Instruct patients who experience symptoms to discontinue Trulicity and promptly seek medical advice.
Renal Impairment: In patients treated with GLP-1 RAs, there have been postmarketing reports of acute renal failure and worsening of chronic renal failure, sometimes requiring hemodialysis. A majority of reported events occurred in patients who had experienced nausea, vomiting, diarrhea, or dehydration. In patients with renal impairment, use caution when initiating or escalating doses of Trulicity and monitor renal function in patients experiencing severe adverse gastrointestinal reactions.
Severe Gastrointestinal Disease: Use of Trulicity may be associated with gastrointestinal adverse reactions, sometimes severe. Trulicity has not been studied in patients with severe gastrointestinal disease, including severe gastroparesis, and is therefore not recommended in these patients.
Macrovascular Outcomes: There have been no clinical studies establishing conclusive evidence of macrovascular risk reduction with Trulicity or any other antidiabetic drug.
The most common adverse reactions reported in > 5% of Trulicity-treated patients in placebo-controlled trials (placebo, Trulicity 0.75 mg, and Trulicity 1.5 mg) were nausea (5.3%, 12.4%, 21.1%), diarrhea (6.7%, 8.9%, 12.6%), vomiting (2.3%, 6.0%, 12.7%), abdominal pain (4.9%, 6.5%, 9.4%), decreased appetite (1.6%, 4.9%, 8.6%), dyspepsia (2.3%, 4.1%, 5.8%), and fatigue (2.6%, 4.2%, 5.6%).
Gastric emptying is slowed by Trulicity, which may impact absorption of concomitantly administered oral medications. Use caution when oral medications are used with Trulicity. Drug levels of oral medications with a narrow therapeutic index should be adequately monitored when concomitantly administered with Trulicity. In clinical pharmacology studies, Trulicity did not affect the absorption of the tested, orally administered medications to a clinically relevant degree.
Pregnancy: There are no adequate and well-controlled studies of Trulicity in pregnant women. Use only if potential benefit outweighs potential risk to fetus.
Nursing Mothers: It is not known whether Trulicity is excreted in human milk. A decision should be made whether to discontinue nursing or to discontinue Trulicity, taking into account the importance of the drug to the mother.
Pediatric Use: Safety and effectiveness of Trulicity have not been established and use is not recommended in patients less than 18 years of age.

Approximately 29 million Americans3 and an estimated 387 million people worldwide have type 1 and type 2 diabetes. Type 2 diabetes is the most common type, accounting for an estimated 90 to 95 percent of all diabetes cases. Diabetes is a chronic disease that occurs when the body either does not properly produce, or use, the hormone insulin. 2
