Short-term effectiveness of low dose liraglutide in combination with metformin versus high dose liraglutide alone in treatment of obese PCOS: randomized trial.

ABSTRACT: Liraglutide 3 mg was recently approved as an anti-obesity drug. Metformin is weight neutral, yet it could enhance the therapeutic index of GLP-1 agonist. We compared weight-lowering potential of liraglutide 1.2 mg in combination with metformin to liraglutide 3 mg monotherapy in obese PCOS.Thirty obese women with PCOS (aged 33.1?±?6.1 years, BMI 38.3?±?5.4 kg/m2) were randomized to combination (COMBO) of metformin (MET) 1000 mg BID and liraglutide 1.2 mg QD (N?=?15) or liraglutide 3 mg (LIRA3) QD alone (N?=?15) for 12 weeks. The primary outcome was change in anthropometric measures of obesity.Both treatments led to significant weight loss (-3.6?±?2.5 kg, p?=?0.002 in COMBO vs -6.3?±?3.7 kg, p?=?0.001 in LIRA3). BMI and waist circumference reduction in LIRA3 was greater than in COMBO (-2.2?±?1.3 vs -1.3?±?0.9 kg/m2, p?=?0.05 and -4.2?±?3.4 vs -2.2?±?6.2 cm, p?=?0.014, respectively). Both interventions resulted in a significant decrease of post-OGTT glucose levels. COMBO significantly reduced total testosterone and was associated with less nausea.Short-term interventions with COMBO and LIRA3 both led to significant improvement of measures of obesity in obese PCOS, LIRA3 being superior to COMBO. However, COMBO further improved androgen profile beyond weight reduction and was associated with better tolerability.The study was retrospectively registered with ClinicalTrials.gov ( NCT02909933 ) on 16th of September 2016.

Project description:BackgroundEffective glycemic control can reduce the risk of serious micro- and macrovascular complications in type 2 diabetes. However, many patients fail to reach glycemic targets due partly to low efficacy and adverse effects of treatment such as hypoglycemia or weight gain.ObjectiveTo evaluate the short-term cost-effectiveness of liraglutide versus sitagliptin, in terms of cost per patient reaching a glycated hemoglobin (HbA1c) target with no hypoglycemia and no weight gain after 52 weeks, based on a recently published trial. MethodsData were taken from a 52-week randomized, controlled trial (NCT00700817) in which adults with type 2 diabetes (mean age = 55 years, HbA1c = 8.4%, body mass index = 33 kg/m2) failing metformin monotherapy were randomly allocated to receive either liraglutide 1.2 mg, liraglutide 1.8 mg, or sitagliptin 100 mg daily, in addition to metformin. For the cost-effectiveness analysis, the proportion of patients achieving a clinically relevant composite endpoint, defined as HbA1c less than 7.0%, with no reported hypoglycemia  and no gain in body weight, was estimated using logistic regression. Trial data showed that 38.9% of patients on liraglutide 1.2 mg and 49.9% on liraglutide 1.8 mg achieved the composite endpoint, compared with 18.6% on sitagliptin at 52 weeks. Costs of antihyperglycemia medications were accounted for based on published wholesale acquisition costs in 2012 U.S. dollars. ResultsOverall pharmacy costs (needle costs included) were higher for patients on liraglutide than sitagliptin. The cost per patient achieving an HbA1c less than 7% was lowest for patients receiving liraglutide 1.2 mg ($7,993) and highest for patients receiving sitagliptin ($11,570). When expressed as the mean cost per patient reaching target HbA1c with no hypoglycemia or weight gain (cost of control), costs were notably lower on liraglutide than on sitagliptin. Annual mean costs of control were $10,335 on liraglutide 1.2 mg and $11,755 on liraglutide 1.8 mg versus $16,858 on sitagliptin.ConclusionThe mean cost per patient achieving control, defined as reaching HbA1c target with no hypoglycemia or weight gain, was lower with liraglutide than with sitagliptin based on data from a recently published 52-week clinical trial.

Project description:ObjectiveThe effect of metformin on weight reduction in polycystic ovary syndrome (PCOS) is often unsatisfactory. In this study, we investigated the potential add-on effect of treatment with the glucagon-like peptide-1 receptor agonist liraglutide on weight loss in obese nondiabetic women with PCOS who had lost <5% body weight during pretreatment with metformin.MethodsA total of 40 obese women with PCOS, who had been pretreated with metformin for at least 6 months, participated in a 12-week open-label, prospective study. They were randomized to one of three treatment arms: metformin (MET) arm 1000 mg BID, liraglutide (LIRA) arm 1.2 mg QD s.c., or combined MET 1000 mg BID and LIRA (COMBI) 1.2 mg QD s.c. Lifestyle intervention was not actively promoted. The primary outcome was change in body weight.ResultsThirty six patients (aged 31.3 ± 7.1 years, BMI 37.1 ± 4.6 kg/m²) completed the study: 14 on MET, 11 on LIRA, and 11 on combined treatment. COMBI therapy was superior to LIRA and MET monotherapy in reducing weight, BMI, and waist circumference. Subjects treated with COMBI lost on average 6.5 ± 2.8 kg compared with a 3.8 ± 3.7 kg loss in the LIRA group and a 1.2 ± 1.4 kg loss in the MET group (P<0.001). The extent of weight loss was stratified: a total of 38% of subjects were high responders who lost ≥5% body weight, 22% of them in the COMBI arm compared with 16 and 0% in the LIRA and MET arm respectively. BMI decreased by 2.4 ± 1.0 in the COMBI arm compared with 1.3 ± 1.3 in LIRA and 0.5 ± 0.5 in the MET arm (P<0.001). Waist circumference also decreased by 5.5 ± 3.8 cm in the COMBI arm compared with 3.2 ± 2.9 cm in LIRA and 1.6 ± 2.9 cm in the MET arm (P=0.029). Subjects treated with liraglutide experienced more nausea than those treated with metformin, but severity of nausea decreased over time and did not correlate with weight loss.ConclusionsShort-term combined treatment with liraglutide and metformin was associated with significant weight loss and decrease in waist circumference in obese women with PCOS who had previously been poor responders regarding weight reduction on metformin monotherapy.

Project description:IntroductionInternational and Danish guidelines recommend the use of glucagon-like peptide 1 receptor agonists (GLP-1 RA) and sodium-glucose cotransporter 2 (SGLT-2) inhibitors already in second line in the management of type 2 diabetes (T2D). The objective of this study was to evaluate the long-term cost-effectiveness (CE) of subcutaneous (SC) semaglutide (GLP-1 RA) versus empagliflozin (SGLT-2 inhibitor) in individuals with T2D uncontrolled on metformin alone from a Danish payer's perspective.MethodsCost-effectiveness analyses (CEA) were conducted from a Danish payer's perspective, using the IQVIA Core Diabetes model (CDM 9.5), with a time horizon of 50 years and an annual discount of 4% on costs and effects. Patients received either SC semaglutide or empagliflozin, in addition to metformin, until HbA1c threshold of 7.5% (58 mmol/mol) was reached, following which treatment intensification with insulin glargine in addition to empagliflozin or SC semaglutide plus metformin was considered. Baseline cohort characteristics and treatment effects were sourced from a published CEA. Utilities and cost of diabetes-related complications were also obtained from published sources. Treatment costs were derived from Danish official sources. Scenario analyses were also performed to test the accuracy of the base case results.ResultsIndividuals with T2D on SC semaglutide plus metformin gained 0.065 life-years (LYs) and 0.130 quality-adjusted LYs (QALYs), respectively, at an incremental cost of DKK 96,923 (€ 13,031) compared to empagliflozin plus metformin, resulting in an incremental cost-effectiveness ratio (ICER) of DKK 745,561(€ 100,239) per QALY gained. The probabilistic sensitivity analysis (PSA) results showed that the SC semaglutide plus metformin was cost-effective in 19% of simulations assuming a willingness-to-pay (WTP) threshold of DKK 357,100 (€ 48,011)/QALY gained. Duration of therapy with SC semaglutide seems the key driver of results.ConclusionThe current analyses suggest that SC semaglutide plus metformin is not cost-effective compared to empagliflozin plus metformin from a Danish payer's perspective.

Project description:PurposeThe KEYNOTE-062 trial demonstrated the efficacy and safety of pembrolizumab for advanced gastric cancer (GC). The current study evaluated the cost-effectiveness of pembrolizumab alone or in combination with chemotherapy versus chemotherapy for advanced GC from the perspective of the United States and China. And the results will provide evidence and data support for more drug selection-related decisions and research in the future.MethodsA partitioned survival approach with three states was created for treatment of advanced GC. The survival data were derived from KEYNOTE-062 trial and the individual patient data were generated by a specific algorithm. We fitted 21 survival functions to each treatment arm and selected the most suitable distribution type for each one. Direct costs and utility values were collected from the published, available database. Cost, quality-adjusted life-years (QALYs), and incremental cost-utility ratios (ICURs) were considered as the primary measure outcomes. One-way and probabilistic sensitivity analyses were performed to assess the reliability of the analyses.ResultsIn the base-case analysis of combined positive score (CPS) ≥1 patients, the ICUR of pembrolizumab plus chemotherapy versus chemotherapy in American and Chinese setting is $345,209/QALY and $186,802.6/QALY, respectively. And the ICUR of pembrolizumab versus chemotherapy is $473,650/QALY and $377,753/QALY in the context of the US and China, respectively. For CPS≥10 patients, the ICUR of pembrolizumab plus chemotherapy versus chemotherapy in American and Chinese setting is $483,742/QALY and $262,965/QALY, respectively. And that of pembrolizumab versus chemotherapy is $96,550/QALY and $67,896/QALY in the context of the US and China.ConclusionCompared with chemotherapy, either pembrolizumab plus chemotherapy or pembrolizumab monotherapy is not regarded as a cost-effective strategy for patients with CPS≥1, advanced gastric cancer in the current American and Chinese setting. But pembrolizumab monotherapy for CPS≥10 patients would become a cost-effective option in the American setting.
