BOSTON, April 2, 2016 /PRNewswire/ -- Findings from a clinical trial comparing Victoza^® (liraglutide [rDNA origin] injection) and sitagliptin (100 mg), both in combination with metformin, demonstrated that switching from sitagliptin to Victoza^® provided superior HbA_1creductions vs continuing with sitagliptin treatment in adults with type 2 diabetes. Results from the LIRA-SWITCH trial were presented at the Endocrine Society's 98^th Annual Meeting and Expo (ENDO 2016) in Boston, Massachusetts.¹

The 26-week LIRA-SWITCH trial assessed the efficacy and safety of Victoza^®as an add-on to metformin in 407 adults with type 2 diabetes who switched from sitagliptin.¹ Of the 407 adults uncontrolled on sitagliptin (HbA_1c 7.5–9.5%) at week 26, those who switched to Victoza^®(n=203) achieved a superior reduction in HbA_1c vs those who continued their sitagliptin treatment (n=204) (−1.14% vs −0.54%; estimated treatment difference [ETD] −0.61%, 95% confidence interval [CI]: −0.82 to −0.40, P<0.0001).¹

Additionally, adults who switched to Victoza^® experienced significantly greater body weight reductions vs those who continued with their sitagliptin dose (−3.31 kg/−7.29 lb vs −1.64 kg/−3.62 lb; ETD −1.67 kg/−3.68 lb, 95% CI: −2.34 to −0.99, P<0.0001).¹

"The LIRA-SWITCH trial results provide valuable insight that adults uncontrolled on sitagliptin may achieve a superior reduction with liraglutide 1.8 mg vs continuing on sitagliptin treatment," said Dr Maximo Maislos, Atherosclerosis and Metabolism Unit, Soroka UMC, Ben-Gurion University FOHS, Beer Sheva-Israel, and investigator of the LIRA-SWITCH trial. "These findings are valuable as there is limited clinical evidence to guide treatment strategy when people with type 2 diabetes are uncontrolled on second-line therapy."

The trial demonstrated that more adults with type 2 diabetes treated with Victoza^®vs sitagliptin achieved HbA_1ctargets <7% (50.6% vs 26.9% OR: 3.36 95%; CI: 2.08 to 5.42 P<0.0001) and ≤6.5% (29.5% vs 9.9%; OR: 5.44; 95% CI: 2.82 to 10.47, P<0.0001 for both).¹Furthermore, adults treated with Victoza^®demonstrated significantly greater reductions in fasting plasma glucose vs those treated with sitagliptin (−33.09 mg/dL vs −13.19 mg/dL; P<0.0001)¹

Adverse events were more common in the Victoza^® group vs the sitagliptin group (68.8% vs. 56.9%), with gastrointestinal side effects more frequent with Victoza^®: nausea (21.8% vs 7.8%) and diarrhea (16.3% vs 9.3%).¹ There were no reports of severe hypoglycemia and no reports of confirmed nocturnal hypoglycemia in either treatment arm.¹

About the LIRA-SWITCH Trial

The 26-week trial was a randomized, double-blind, double-dummy, active-controlled trial involving 407 adults with type 2 diabetes not achieving adequate glycemic control on sitagliptin as add-on to metformin.¹ Trial participants were previously treated with stable doses of sitagliptin (100 mg daily) and metformin (≥1500 mg daily or maximum tolerated dose ≥1000 mg daily) for ≥90 days.¹ Participants were randomized 1:1 to switch to Victoza^® 1.8 mg or continue sitagliptin 100 mg, both in combination with metformin.¹

It is not known if Victoza^® will cause thyroid tumors or a type of thyroid cancer called medullary thyroid carcinoma (MTC) in people.

Please see additional Important Safety Information on next page.

Who should not use Victoza^®(liraglutide [rDNA origin] injection)?

Do not use Victoza^® if:

you or any of your family have ever had a type of thyroid cancer called medullary thyroid carcinoma (MTC) or if you have an endocrine system condition called Multiple Endocrine Neoplasia syndrome type 2 (MEN 2).
you are allergic to liraglutide or any of the ingredients in Victoza^®.

What should I tell my health care provider before using Victoza^®?

Before using Victoza^®, tell your health care provider if you:
