A randomized, double-blind trial assessing the efficacy and safety of two doses of dulaglutide in Japanese participants with type 2 diabetes (AWARD-JPN).

AIM: To assess the efficacy and safety of dulaglutide 1.5 mg versus dulaglutide 0.75 mg in Japanese participants with type 2 diabetes (T2D). MATERIALS AND METHODS: A Phase 3, multicentre, randomized, double-blind, parallel-group study was conducted in Japanese participants aged ≥20 years, with T2D for ≥6 months and inadequate glycaemic control, while on a single oral antihyperglycaemic medication (NCT04809220). The primary objective was to evaluate superiority of dulaglutide 1.5 mg versus dulaglutide 0.75 mg measured by mean change in glycated haemoglobin (HbA1c) from baseline to 26 weeks. Other efficacy and safety endpoints were evaluated at 26 and 52 weeks. All statistical analyses were conducted using the intention-to-treat population. RESULTS: Overall, 591 participants were randomized to once-weekly dulaglutide 1.5 mg or 0.75 mg. At Week 26, dulaglutide 1.5 mg was superior to dulaglutide 0.75 mg in HbA1c reduction from baseline (least squares mean [LSM] difference -0.29% [95% confidence interval {CI} -0.43, -0.14]). At Week 52, the dulaglutide 1.5-mg arm had a significantly greater proportion of participants who achieved HbA1c <7.0% (46.3% vs. 38.5%; p = 0.03) and showed significantly greater reduction in fasting serum glucose (LSM difference -9.4 mg/dL [95% CI -14.4, -4.3]; p < 0.001) versus the dulaglutide 0.75-mg arm. No statistically significant change in body weight was observed in either treatment arm. Overall, 442 participants (75.4%) experienced treatment emergent adverse events (TEAEs). Constipation (11.3%), diarrhoea (9.6%) and pyrexia (9.0%) were the most commonly reported TEAEs. CONCLUSIONS: Dulaglutide 1.5 mg once weekly demonstrated superior glycaemic control versus dulaglutide 0.75 mg once weekly, with comparable safety and tolerability, in Japanese people with T2D.

Long-term efficacy and safety of enavogliflozin in Korean people with type 2 diabetes: A 52-week extension of a Phase 3 randomized controlled trial.

AIMS: To evaluate the long-term safety and efficacy of enavogliflozin monotherapy (0.3 mg/day) in individuals with type 2 diabetes mellitus (T2DM). MATERIALS AND METHODS: Following a 24-week randomized, double-blind treatment period with enavogliflozin 0.3 mg/day (n = 77) or placebo (n = 69), consenting participants received enavogliflozin 0.3 mg/day for an additional 28 weeks during an open-label extension (OLE) period. The safety and efficacy of enavogliflozin were assessed at Week 52. RESULTS: A total of 37 participants continued enavogliflozin (maintenance group), and 26 participants switched from placebo to enavogliflozin (switch group). No additional adverse drug reactions related to enavogliflozin were observed during the OLE period. At Week 52, glycated haemoglobin (HbA1c) and fasting plasma glucose were significantly lower than at the baseline, by 0.9% and 24.9 mg/dL, respectively, in the maintenance group (p < 0.0001 for both), and by 0.7% and 18.0 mg/dL, respectively, in the switch group (p < 0.0001 and p = 0.002). The proportions of participants reaching HbA1c 7.0% (53 mmol/mol) at Week 52 were 69.4% in the maintenance group and 65.4% in the switch group. A significant increase in urine glucose-to-creatinine ratio was observed at Week 52, by 84.9 g/g and 67.1 g/g in the maintenance and switch groups, respectively (p < 0.0001 for both). Body weight in both groups decreased significantly (p < 0.0001) from baseline to Week 52, by 3.5 kg and 3.8 kg in the maintenance and switch groups, respectively. CONCLUSIONS: Enavogliflozin 0.3 mg monotherapy provides long-term glycaemic control in T2DM and is safe and well tolerated during a 52-week treatment period.

Ultra-rapid lispro improved postprandial glucose control compared to insulin lispro in predominantly Chinese patients with type 1 diabetes: A prospective, randomized, double-blind phase 3 study.

AIMS: To investigate the efficacy and safety of ultra-rapid lispro (URLi) versus insulin lispro in predominantly Chinese patients with type 1 diabetes (T1D) in a prospective, randomized, double-blind, treat-to-target, phase 3 study. MATERIALS AND METHODS: Following a lead-in period, during which insulin glargine U-100 or insulin degludec U-100 was optimized, patients were randomly assigned (1:1) to URLi (n = 176) or insulin lispro (n = 178). The primary objective was to test the noninferiority of URLi to insulin lispro in glycaemic control (noninferiority margin = 0.4% for glycated haemoglobin [HbA1c] change from baseline to week 26), with testing for the superiority of URLi to insulin lispro with regard to 1- and 2-hour postprandial glucose (PPG) excursions during a mixed-meal tolerance test and HbA1c change at week 26 as the multiplicity-adjusted objectives. RESULTS: From baseline to week 26, HbA1c decreased by 0.21% and 0.28% with URLi and insulin lispro, respectively, with a least squares mean treatment difference of 0.07% (95% confidence interval -0.11 to 0.24; P = 0.467). URLi demonstrated smaller 1- and 2-hour PPG excursions at week 26 with least squares mean treatment differences of -1.0 mmol/L (-17.8 mg/dL) and -1.4 mmol/L (-25.5 mg/dL), respectively (p < 0.005 for both) versus insulin lispro. The safety profiles of URLi and insulin lispro were similar. CONCLUSIONS: In this study, URLi administered in a basal-bolus regimen demonstrated superiority to insulin lispro in controlling PPG excursions, with noninferiority of HbA1c control in predominantly Chinese patients with T1D.

Durvalumab with or without tremelimumab versus the EXTREME regimen as first-line treatment for recurrent or metastatic squamous cell carcinoma of the head and neck: KESTREL, a randomized, open-label, phase III study.

BACKGROUND: Patients with recurrent or metastatic head and neck squamous cell carcinoma (R/M HNSCC) have a poor prognosis. The phase III KESTREL study evaluated the efficacy of durvalumab [programmed death-ligand 1 (PD-L1) antibody] with or without tremelimumab [cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) antibody], versus the EXTREME regimen in patients with R/M HNSCC. PATIENTS AND METHODS: Patients with HNSCC who had not received prior systemic treatment for R/M disease were randomized (2 : 1 : 1) to receive durvalumab 1500 mg every 4 weeks (Q4W) plus tremelimumab 75 mg Q4W (up to four doses), durvalumab monotherapy 1500 mg Q4W, or the EXTREME regimen (platinum, 5-fluorouracil, and cetuximab) until disease progression. Durvalumab efficacy, with or without tremelimumab, versus the EXTREME regimen in patients with PD-L1-high tumors and in all randomized patients was assessed. Safety was also assessed. RESULTS: Durvalumab and durvalumab plus tremelimumab were not superior to EXTREME for overall survival (OS) in patients with PD-L1-high expression [median, 10.9 and 11.2 versus 10.9 months, respectively; hazard ratio (HR) = 0.96; 95% confidence interval (CI) 0.69-1.32; P = 0.787 and HR = 1.05; 95% CI 0.80-1.39, respectively]. Durvalumab and durvalumab plus tremelimumab prolonged duration of response versus EXTREME (49.3% and 48.1% versus 9.8% of patients remaining in response at 12 months), correlating with long-term OS for responding patients; however, median progression-free survival was longer with EXTREME (2.8 and 2.8 versus 5.4 months). Exploratory analyses suggested that subsequent immunotherapy use by 24.3% of patients in the EXTREME regimen arm contributed to the similar OS outcomes between arms. Grade 3/4 treatment-related adverse events (TRAEs) for durvalumab, durvalumab plus tremelimumab, and EXTREME were 8.9%, 19.1%, and 53.1%, respectively. CONCLUSIONS: In patients with PD-L1-high expression, OS was comparable between durvalumab and the EXTREME regimen. Durvalumab alone, and with tremelimumab, demonstrated durable responses and reduced TRAEs versus the EXTREME regimen in R/M HNSCC.

Safety and tolerability of semaglutide across the SUSTAIN and PIONEER phase IIIa clinical trial programmes.

AIM: Glucagon-like peptide-1 receptor agonists improve glycaemic control: some are now available as oral and subcutaneous formulations, and some have indications for reducing cardiovascular risk. The expanded scope for these therapies warrants comprehensive safety evaluations. We report the safety/tolerability of subcutaneous and oral semaglutide from the SUSTAIN and PIONEER clinical trial programmes, respectively. MATERIALS AND METHODS: Adverse events (AEs) from 16 randomized placebo- or active-controlled phase IIIa trials in patients with type 2 diabetes (n = 11 159) including once-weekly subcutaneous semaglutide (n = 3150; SUSTAIN trials) or once-daily oral semaglutide (n = 4116; PIONEER trials) were analysed. Data pools were analysed for each programme, with separate analyses of cardiovascular outcomes trials (CVOTs; n = 6480). RESULTS: In the phase IIIa pools, gastrointestinal disorders were reported in 41.9%/39.1% of patients with subcutaneous/oral semaglutide, respectively (most prevalent during initiation/escalation) versus 22.0%/24.8% with comparators. Rates of kidney disorders, acute pancreatitis, malignant neoplasms, hypoglycaemia, diabetic retinopathy, heart failure and other cardiovascular events were similar for semaglutide versus comparators. Cholelithiasis incidence was higher with subcutaneous and oral semaglutide versus placebo. Diabetic retinopathy incidence was higher with subcutaneous semaglutide versus placebo in SUSTAIN 6. Small pulse rate increases occurred with both formulations; there was no increased rate of arrhythmias. Fatal AE incidence was similar between semaglutide and comparators. Versus placebo, CVOTs showed a reduced risk of major adverse cardiovascular events with subcutaneous semaglutide and non-inferiority criteria were met with oral semaglutide. CONCLUSIONS: The most common AEs with semaglutide were gastrointestinal disorders, which decreased with continued therapy. These comprehensive safety/tolerability data may better inform patient selection and guidance in care.

Rationale and design of the phase 3a development programme (ONWARDS 1-6 trials) investigating once-weekly insulin icodec in diabetes.

AIM: To describe the phase 3a ONWARDS clinical development programme investigating insulin icodec (icodec), a once-weekly basal insulin, including the design and rationale for each of the ONWARDS 1-6 trials. MATERIALS AND METHODS: Six randomized controlled trials have been initiated in adults with type 2 diabetes (T2D) (insulin-naive: ONWARDS 1, 3 and 5; previously insulin-treated: ONWARDS 2 and 4) and type 1 diabetes (T1D) (ONWARDS 6). Each trial will investigate icodec use in a unique clinical scenario, with consideration of long-term safety and varied comparator treatments (insulin glargine U100 or U300 or insulin degludec). ONWARDS 5 will incorporate real-world elements and a digital dose titration solution to guide icodec dosing. The primary objective for each of the trials is to compare the change in HbA1c from baseline to week 26 or week 52 between icodec and comparator arms. Secondary objectives include investigating other glycaemic control and safety parameters, such as fasting glucose, time in glycaemic range and hypoglycaemia. Patient-reported outcomes will assess treatment satisfaction. CONCLUSIONS: The ONWARDS 1-6 trials will evaluate the efficacy and safety of once-weekly icodec compared with currently available daily basal insulin analogues in T2D and T1D. These trials will generate comprehensive evidence of icodec use in diverse populations across the spectrum of diabetes progression and treatment experience.

The impact of obesity on cardiovascular and kidney outcomes in patients with chronic kidney disease and type 2 diabetes treated with finerenone: Post hoc analysis of the FIDELITY study.

AIM: To assess the effect of finerenone on the risk of cardiovascular and kidney outcomes in patients with chronic kidney disease and type 2 diabetes, with and without obesity. MATERIALS AND METHODS: A post hoc analysis of the prespecified pooled FIDELITY dataset assessed the association between waist circumference (WC), composite cardiovascular and kidney outcomes, and the effects of finerenone. Participants were stratified by WC risk groups (representing visceral obesity) as low-risk or high-very high-risk (H-/VH-risk). RESULTS: Of 12 986 patients analysed, 90.8% occupied the H-/VH-risk WC group. Incidence of the composite cardiovascular outcome was similar between finerenone and placebo in the low-risk WC group (hazard ratio [HR] 1.03; 95% confidence interval [CI], 0.72-1.47); finerenone reduced the risk in the H-/VH-risk WC group (HR 0.85; 95% CI, 0.77-0.93). For the kidney outcome, the risk was similar in the low-risk WC group (HR 0.98; 95% CI, 0.66-1.46) and reduced within the H-/VH-risk WC group (HR 0.75; 95% CI, 0.65-0.87) with finerenone versus placebo. There was no significant heterogeneity between the low-risk and H-/VH-risk WC groups for cardiovascular and kidney composite outcomes (P interaction = .26 and .34, respectively). The apparent greater benefit of finerenone on cardiorenal outcomes but lack of significant heterogeneity observed in H-/VH-risk WC patients may be because of the small size of the low-risk group. Adverse events were consistent across WC groups. CONCLUSION: In FIDELITY, benefits of finerenone in lowering the risk of cardiovascular and kidney outcomes were not significantly modified by patient obesity.

Glycaemic variability in patients with type 2 diabetes mellitus treated with dulaglutide, with and without concomitant insulin: Post hoc analyses of randomized clinical trials.

AIM: To investigate the association between treatment with dulaglutide and glycaemic variability (GV) in adult patients with type 2 diabetes mellitus (T2D). MATERIALS AND METHODS: Post hoc analyses of six randomized, phase 3 studies were conducted to investigate the association between treatment with dulaglutide 1.5 mg once weekly and GV in adult patients with T2D. Using data from seven- and eight-point self-monitored plasma glucose (SMPG) profiles over up to 28 weeks of treatment, GV in within- and between-day SMPG, and between-day fasting glucose from SMPG (FSMPG) was assessed according to standard deviation and coefficient of variation. RESULTS: Pooled data from five studies with dulaglutide as monotherapy or added to oral glucose-lowering medication, without concomitant insulin treatment, revealed clinically meaningful reductions in within- and between-day SMPG, and between-day FSMPG variability from baseline in the dulaglutide group. Comparisons between treatment groups in two studies demonstrated that reductions from baseline in within-day and between-day SMPG, and between-day FSMPG variability were greater for treatment with dulaglutide compared with insulin glargine, as well as for treatment with dulaglutide when added to insulin glargine compared with insulin glargine alone. CONCLUSIONS: In patients with T2D, treatment with dulaglutide as monotherapy or added to oral glucose-lowering medication, without concomitant insulin treatment, was potentially associated with a reduction in GV. Treatment with dulaglutide was associated with a reduction in GV to a greater degree than insulin glargine. When added to insulin glargine, treatment with dulaglutide was associated with greater decreases in GV compared with insulin glargine alone. As reduced GV may be associated with better outcomes, these findings may have clinical relevance.

Long-term effects of dapagliflozin plus saxagliptin versus glimepiride on a background of metformin in patients with type 2 diabetes: Results of a 104-week extension to a 52-week randomized, phase 3 study and liver fat MRI substudy.

AIM: To report the results of a 104-week extension to a 52-week study in which dapagliflozin plus saxagliptin (DAPA+SAXA) improved glycaemic control, liver fat and metabolic variables compared with glimepiride (GLIM) in participants with type 2 diabetes (T2D) receiving background metformin. MATERIALS AND METHODS: This extension to a 52-week global, multicentre, parallel-group, active-controlled, double-blind study (NCT02419612) continued randomized participants (1:1) on DAPA+SAXA (10/5 mg) plus placebo, or GLIM (1-6 mg) plus placebo, once daily. Eligible participants were aged ≥18 years, had T2D (glycated haemoglobin [HbA1c] 58.5-91.3 mmol/mol [7.5%-10.5%]), and a body mass index of 20.0 to 45.0 kg/m2 , and were receiving metformin (MET; ≥1500 mg/d). Key outcomes were: requirement for treatment intensification, based on HbA1c ≥53 mmol/mol (7%); achieving therapeutic glycaemic response; and changes in adipose tissue and liver fat on magnetic resonance imaging in a substudy. RESULTS: Overall, 382 participants entered and 338 completed the 104-week extension period (MRI substudy, n = 82). The need for treatment intensification during the 156-week period was lower for DAPA+SAXA+MET (37.0%) than GLIM+MET (55.6%; hazard ratio 0.52, 95% confidence interval [CI] 0.39-0.68; P < 0.001). At week 156, 21.4% of DAPA+SAXA+MET versus 11.7% of GLIM+MET participants achieved therapeutic glycaemic response (HbA1c <53 mmol/mol; odds ratio 2.1, 95% CI 1.23-3.42; P = 0.006). DAPA+SAXA+MET led to greater adjusted mean reductions from baseline in liver fat and visceral and subcutaneous adipose tissue volumes versus GLIM+MET at week 122 (least-squares mean difference from GLIM+MET -4.89%, -0.41 L and -0.44 L, respectively; nominal P values ≤ 0.008). Safety was consistent with that of the monocomponents. CONCLUSIONS: Overall, glycaemic control, metabolic benefits and efficacy were better maintained with DAPA+SAXA+MET than with GLIM+MET in T2D.

Weight regain and cardiometabolic effects after withdrawal of semaglutide: The STEP 1 trial extension.

AIM: To explore changes in body weight and cardiometabolic risk factors after treatment withdrawal in the STEP 1 trial extension. MATERIALS AND METHODS: STEP 1 (NCT03548935) randomized 1961 adults with a body mass index ≥ 30 kg/m2 (or ≥ 27 kg/m2 with ≥ 1 weight-related co-morbidity) without diabetes to 68 weeks of once-weekly subcutaneous semaglutide 2.4 mg (including 16 weeks of dose escalation) or placebo, as an adjunct to lifestyle intervention. At week 68, treatments (including lifestyle intervention) were discontinued. An off-treatment extension assessed for a further year a representative subset of participants who had completed 68 weeks of treatment. This subset comprised all eligible participants from any site in Canada, Germany and the UK, and sites in the United States and Japan with the highest main phase recruitment. All analyses in the extension were exploratory. RESULTS: Extension analyses included 327 participants. From week 0 to week 68, mean weight loss was 17.3% (SD: 9.3%) with semaglutide and 2.0% (SD: 6.1%) with placebo. Following treatment withdrawal, semaglutide and placebo participants regained 11.6 (SD: 7.7) and 1.9 (SD: 4.8) percentage points of lost weight, respectively, by week 120, resulting in net losses of 5.6% (SD: 8.9%) and 0.1% (SD: 5.8%), respectively, from week 0 to week 120. Cardiometabolic improvements seen from week 0 to week 68 with semaglutide reverted towards baseline at week 120 for most variables. CONCLUSIONS: One year after withdrawal of once-weekly subcutaneous semaglutide 2.4 mg and lifestyle intervention, participants regained two-thirds of their prior weight loss, with similar changes in cardiometabolic variables. Findings confirm the chronicity of obesity and suggest ongoing treatment is required to maintain improvements in weight and health.

Gastrointestinal tolerability of once-weekly semaglutide 2.4 mg in adults with overweight or obesity, and the relationship between gastrointestinal adverse events and weight loss.

AIM: We evaluated gastrointestinal (GI) adverse events (AEs) with once-weekly semaglutide 2.4 mg in adults with overweight or obesity and their contribution to weight loss (WL). MATERIALS AND METHODS: AE analyses pooled data from the Semaglutide Treatment Effect in People With Obesity (STEP) 1-3 trials for participants randomized to 68 weeks of semaglutide 2.4 mg (n = 2117) or placebo (n = 1262). WL was analysed by presence/absence of GI AEs. Mediation analysis estimated WL effects mediated by and unrelated to GI AEs. GI tolerability with semaglutide 2.4 mg maintenance and cessation after dose escalation was evaluated using STEP 4 data among 803 participants tolerating 20 weeks of semaglutide run-in. RESULTS: GI AEs were more common with semaglutide 2.4 mg than placebo, with most frequently nausea (43.9% vs. 16.1% of participants), diarrhoea (29.7% vs. 15.9%), vomiting (24.5% vs. 6.3%) and constipation (24.2% vs. 11.1%). Most GI AEs with semaglutide were non-serious (99.5% of AEs), mild-to-moderate (98.1%), transient and occurred most frequently during/shortly after dose escalation. Few semaglutide-treated participants (4.3%) permanently discontinued treatment for GI AEs. In STEP 1-3, mean WL with semaglutide 2.4 mg was similar in participants without (9.6%-17.1%) versus with GI AEs (11.4%-17.7%). Consistent with this observation, mediation analysis found that GI AEs contributed little to semaglutide-induced WL: of the additional 7.6%-14.4% WL with semaglutide versus placebo, <1 percentage point was mediated by GI AEs. In STEP 4, semaglutide 2.4 mg maintenance was well tolerated. CONCLUSIONS: GI AEs were more common with semaglutide 2.4 mg than placebo, but typically mild-to-moderate and transient. Semaglutide-induced WL was largely independent of GI AEs.

Pembrolizumab for the treatment of advanced esophageal cancer.

The prognosis of patients with advanced esophageal cancer (EC) remains poor and there are limited effective therapeutic agents for EC. Pembrolizumab monotherapy exerts clinically meaningful benefits for advanced esophageal squamous cell carcinoma patients with a combined positive score of ≥10. Additionally, pembrolizumab plus doublet chemotherapy results in a significant survival benefit for patients with advanced EC as first-line treatment compared with chemotherapy alone. We provide an overview of immune checkpoint inhibitors and present important clinical data related to treatment for EC patients. In our opinion, pembrolizumab plus chemotherapy should be the standard first-line treatment for patients with advanced EC, regardless of histology and combined positive score. Biomarker studies to identify patient populations in which immune checkpoint inhibitors are expected to show efficacy are needed.

Lurbinectedin versus pegylated liposomal doxorubicin or topotecan in patients with platinum-resistant ovarian cancer: A multicenter, randomized, controlled, open-label phase 3 study (CORAIL).

OBJECTIVE: The randomized phase 3 CORAIL trial evaluated whether lurbinectedin improved progression-free survival (PFS) compared to pegylated liposomal doxorubicin (PLD) or topotecan in patients with platinum-resistant ovarian cancer. METHODS: Patients were randomly assigned (1:1) to lurbinectedin 3.2 mg/m2 1-h i.v. infusion q3wk (experimental arm), versus PLD 50 mg/m2 1-h i.v. infusion q4wk or topotecan 1.50 mg/m2 30-min i.v. infusion Days 1-5 q3wk (control arm). Stratification factors were PS (0 vs. ≥1), prior PFI (1-3 months vs. >3 months), and prior chemotherapy lines (1-2 vs. 3). The primary endpoint was PFS by Independent Review Committee in all randomized patients. This study was registered with ClinicalTrials.gov, NCT02421588. RESULTS: 442 patients were randomized: 221 in lurbinectedin arm and 221 in control arm (127 PLD and 94 topotecan). With a median follow-up of 25.6 months, median PFS was 3.5 months (95% CI, 2.1-3.7) in the lurbinectedin arm and 3.6 months (95% CI, 2.7-3.8) in the control arm (stratified log-rank p = 0.6294; HR = 1.057). Grade ≥ 3 treatment-related adverse events (AEs) were most frequent in the control arm: 64.8% vs. 47.9% (p = 0.0005), mainly due to hematological toxicities. The most common grade ≥ 3 AEs were: fatigue (7.3% of patients) and nausea (5.9%) with lurbinectedin; mucosal inflammation (8.5%) and fatigue (8.0%) in the control arm. CONCLUSIONS: The primary endpoint of improvement in PFS was not met. Lurbinectedin showed similar antitumor efficacy and was better tolerated than current standard of care in patients with platinum-resistant ovarian cancer.

Effects of dapagliflozin on prevention of major clinical events and recovery in patients with respiratory failure because of COVID-19: Design and rationale for the DARE-19 study.

AIMS: Coronavirus disease 2019 (COVID-19) is caused by a novel severe acute respiratory syndrome coronavirus 2. It can lead to multiorgan failure, including respiratory and cardiovascular decompensation, and kidney injury, with significant associated morbidity and mortality, particularly in patients with underlying metabolic, cardiovascular, respiratory or kidney disease. Dapagliflozin, a sodium-glucose cotransporter-2 inhibitor, has shown significant cardio- and renoprotective benefits in patients with type 2 diabetes (with and without atherosclerotic cardiovascular disease), heart failure and chronic kidney disease, and may provide similar organ protection in high-risk patients with COVID-19. MATERIALS AND METHODS: DARE-19 (NCT04350593) is an investigator-initiated, collaborative, international, multicentre, randomized, double-blind, placebo-controlled study testing the dual hypotheses that dapagliflozin can reduce the incidence of cardiovascular, kidney and/or respiratory complications or all-cause mortality, or improve clinical recovery, in adult patients hospitalized with COVID-19 but not critically ill on admission. Eligible patients will have ≥1 cardiometabolic risk factor for COVID-19 complications. Patients will be randomized 1:1 to dapagliflozin 10 mg or placebo. Primary efficacy endpoints are time to development of new or worsened organ dysfunction during index hospitalization, or all-cause mortality, and the hierarchical composite endpoint of change in clinical status through day 30 of treatment. Safety of dapagliflozin in individuals with COVID-19 will be assessed. CONCLUSIONS: DARE-19 will evaluate whether dapagliflozin can prevent COVID-19-related complications and all-cause mortality, or improve clinical recovery, and assess the safety profile of dapagliflozin in this patient population. Currently, DARE-19 is the first large randomized controlled trial investigating use of sodium-glucose cotransporter 2 inhibitors in patients with COVID-19.

Efficacy and safety of once-weekly semaglutide versus once-daily sitagliptin as add-on to metformin in patients with type 2 diabetes in SUSTAIN China: A 30-week, double-blind, phase 3a, randomized trial.

AIM: To evaluate the efficacy and safety of once-weekly subcutaneous semaglutide, a glucagon-like peptide-1 (GLP-1) analogue, versus once-daily sitagliptin as add-on to metformin in patients with type 2 diabetes (T2D) in a multiregional clinical trial. MATERIALS AND METHODS: In the 30-week, randomized, double-blind, double-dummy, active comparator SUSTAIN China trial, 868 adults with T2D inadequately controlled on metformin (HbA1c 7.0%-10.5%) were randomized to receive once-weekly semaglutide 0.5 mg (n = 288), semaglutide 1.0 mg (n = 290) or once-daily sitagliptin 100 mg (n = 290). The primary and confirmatory secondary endpoints were change from baseline to week 30 in HbA1c and body weight, respectively. RESULTS: The trial enrolled ~70% (605/868) of the patients in China, and the remaining patients from four other countries, including the Republic of Korea. Both doses of semaglutide were superior to sitagliptin in reducing HbA1c and body weight after 30 weeks of treatment. The odds of achieving target HbA1c of less than 7.0% (53 mmol/mol), weight loss of 5% or higher, or 10% or higher, and the composite endpoint of HbA1c less than 7.0% (53 mmol/mol) without severe or blood glucose-confirmed symptomatic hypoglycaemia no weight gain, were all significantly higher with both semaglutide doses compared with sitagliptin. The safety profile for semaglutide was consistent with the known class effects of GLP-1 receptor agonists (RAs). Consistent efficacy and safety findings were seen in the Chinese subpopulation. CONCLUSIONS: Once-weekly semaglutide was superior to sitagliptin in improving glycaemic control and reducing body weight in patients with T2D inadequately controlled on metformin. The safety and tolerability profiles were consistent with those of semaglutide and other GLP-1 RAs. Semaglutide is an effective once-weekly treatment option for the Chinese population.

Efficacy and safety of linagliptin as add-on therapy to insulin in Chinese patients with type 2 diabetes mellitus: A randomized, double-blind, placebo-controlled trial.

This 24-week, double-blind, placebo-controlled, phase III trial evaluated the efficacy and safety of linagliptin in 206 Chinese patients with inadequately controlled (glycated haemoglobin [HbA1c] 7.5%-10.0%) type 2 diabetes mellitus (T2DM) receiving insulin (basal or premixed) ± metformin. Patients were randomized (1:1) to receive linagliptin 5 mg/d or placebo. The decrease from baseline in HbA1c (primary endpoint) was greater with linagliptin than with placebo (-0.61% vs. -0.20%, adjusted mean difference -0.40%; P = 0.0016). Linagliptin demonstrated significantly greater improvement in 2-hour postprandial glucose (-1.77 mmol/L [-31.95 mg/dL]; P < 0.001), and a numerical reduction in fasting plasma glucose (-0.34 mmol/L [-6.2 mg/dL]; P = 0.2241) versus placebo. Proportionally more patients on linagliptin achieved a HbA1c reduction of ≥0.5% versus those on placebo (odds ratio 2.293, P < 0.01). Adverse events in both groups were similar, with no new safety findings or clinically relevant changes in body weight. Among investigator-defined hypoglycaemic events (linagliptin: 17.3%; placebo: 12.7%; odds ratio 1.48, P = 0.337), none were severe. In Chinese patients with T2DM, linagliptin add-on to insulin improved glycaemic control and was well tolerated, without increased risk of hypoglycaemia or weight gain.

Extended-release naltrexone/bupropion and liver health: Pooled, post hoc analysis from four randomized controlled trials.

Sustained weight loss improves liver histology in non-alcoholic fatty liver disease. This post hoc analysis of four phase III, 56-week, randomized controlled trials investigated if extended-release naltrexone and bupropion (NB) affects alanine aminotransferase (ALT) and Fibrosis-4 (FIB-4) index in adults with overweight or obesity. Two thousand and seventy-three subjects (NB = 1310; placebo = 763; 79.0% female; 81.6% Caucasian) had baseline mean weight 101 kg, body mass index 36.2 kg/m2 , ALT 26.9 IU/L and FIB-4 0.79. At 56 weeks, NB-treated subjects experienced more weight loss than placebo (8.7 vs. 3.2 kg, respectively, P < .0001). Weight loss, independent of treatment, was associated with improved ALT and FIB-4 (P < .0001). There was a significant independent effect of NB on change from baseline for FIB-4 (P < .0001), but not for ALT (P = .54). Categorical ALT response (from above to within normal ranges: 10-40 IU/L for men; 7-35 IU/L for women) and achievement of 25% and 50% reduction in ALT were greater for NB versus placebo, and independently affected by weight loss (P < .0001), but not treatment. NB-associated weight loss may improve liver health by normalizing ALT values for those with high baseline levels.

Efficacy and safety of exenatide as add-on therapy for patients with type 2 diabetes with an intensive insulin regimen: A randomized double-blind trial.

AIM: To assess the safety and efficacy of the short-acting glucagon-like peptide-1 receptor agonist exenatide on a population of patients with type 2 diabetes (T2D) mostly treated with continuous subcutaneous insulin injection (CSII). MATERIALS AND METHODS: A phase 2/3, multicentre, randomized, parallel-group, double-blind, placebo-controlled, 6-month trial was conducted. Patients were randomized to receive subcutaneous (SC) injections of exenatide (10 µg BID) or matched placebo. RESULTS: A total of 46 patients with T2D and elevated HbA1c were randomized (42% of the planned sample size): exenatide (n = 28) and placebo (n = 18). CSII treatment was used by 75% and 89% of patients of the exenatide and placebo groups, respectively. At 6 months, the change in HbA1c was -0.62% ± 0.94% and 0.08% ± 0.81% in the exenatide and placebo groups, respectively (difference, -0.70%; 95% CI [-1.24%; -0.15%], P = .014); body weight and body mass index decreased in the exenatide group (-2.55 ± 3.25 kg and -1.00 ± 1.31 kg/m2 ) and increased in the placebo group (1.29 ± 2.82 kg and 0.46 ± 1.16 kg/m2 ) (observed difference, -3.85 and -1.45, respectively, both P < .001); the postdinner capillary blood glucose value was lower in the exenatide group compared with the placebo group (162.4 ± 80.5 vs. 259.1 ± 94.4 mg/dL, respectively; observed difference, -96.7, P < .01). Hypoglycaemic risk, quality of life and overall safety were not different between the groups, apart from the expected occurrence of digestive effects in the exenatide group. CONCLUSIONS: Although we failed to reach our planned sample size, the addition of exenatide treatment 10 µg BID SC in T2D patients with uncontrolled HbA1c despite an intensified insulin regimen, resulted in a significant reduction of HbA1c and body weight with a good overall safety profile and acceptance.

FRESCO-2: a global Phase III study investigating the efficacy and safety of fruquintinib in metastatic colorectal cancer.

Fruquintinib, a novel, highly selective, small-molecule tyrosine kinase inhibitor of VEGF receptors (VEGFRs)-1, -2 and -3, is approved in China for the treatment of metastatic colorectal cancer. FRESCO-2, a global, randomized, double-blind, placebo-controlled, Phase III study, is investigating the efficacy and safety of fruquintinib in patients with refractory metastatic colorectal cancer. Key inclusion criteria include: progression on or intolerance to TAS-102 and/or regorafenib; and prior treatment with approved chemotherapy, anti-VEGF therapy, and, if RAS wild-type, anti-EGFR therapy. Approximately 687 patients will be randomized 2:1 to fruquintinib plus best supportive care or placebo plus best supportive care. Primary and key secondary end points are overall survival and progression-free survival, respectively. FRESCO-2 is enrolling in the USA, Europe, Australia and Japan.

Lay abstract Fruquintinib is a drug that slows down, reduces or prevents the growth of vessels that supply blood to certain tumors. Fruquintinib is approved in China for the treatment of cancer of the colon and rectum that has spread to these parts of the body from the primary site of cancer: metastatic colorectal cancer. The FRESCO-2 study is being conducted globally to determine how safe and effective fruquintinib is at treating patients with metastatic colorectal cancer that has grown or spread following other forms of treatment, such as chemotherapy. About 687 patients will be enrolled globally to receive either fruquintinib or a matching placebo in a 2:1 ratio, respectively. The FRESCO-2 study is enrolling patients in the USA, Europe, Australia and Japan. Clinical trial registration: NCT04322539 (ClinicalTrials.gov).

iGlarLixi effectively reduces residual hyperglycaemia in patients with type 2 diabetes on basal insulin: A post hoc analysis from the LixiLan-L study.

Globally, nearly half of patients with type 2 diabetes (T2D) do not successfully achieve target HbA1c with basal insulin, despite meeting fasting plasma glucose (FPG) targets. In this post hoc analysis of the LixiLan-L study, we determined whether iGlarLixi, a fixed-ratio combination of insulin glargine Gla-100 (iGlar) and the glucagon-like peptide-1 receptor agonist lixisenatide (Lixi), addresses the challenge of reducing residual hyperglycaemia in patients with T2D. In LixiLan-L, a randomized, open-label study, 1018 patients with T2D on basal insulin for ≥6 months ± oral antidiabetes drugs entered a 6-week run-in period, during which they were switched to and/or optimized for a daily dose of iGlar while continuing only metformin. Following the run-in period, 736 patients were then randomized to receive iGlarLixi or were continued on iGlar for 30 weeks ± metformin. Residual hyperglycaemia was defined as HbA1c ≥ 7.0% despite FPG of <140 mg/dL. The proportion of patients with residual hyperglycaemia was similar in both treatment arms at screening (~~42%), and increased after the run-in period (~~62%). After 30 weeks, the proportion of patients with residual hyperglycaemia declined to 23.8% in the iGlarLixi versus 47.1% in the iGlar arm (P < .0001). The proportion of patients achieving both HbA1c (<7.0%) and FPG (<140 mg/dL) targets was higher in the iGlarLixi compared with the iGlar arm (50.3% vs. 27.4%, respectively; P < .0001). iGlarLixi effectively reduces residual hyperglycaemia in patients with T2D on basal insulin therapy.
