TENAYA and LUCERNE: Two-Year Results from the Phase 3 Neovascular Age-Related Macular Degeneration Trials of Faricimab with Treat-and-Extend Dosing in Year 2

PurposeTo evaluate the 2-year efficacy, durability, and safety of the bispecific antibody, faricimab, which inhibits both angiopoietin-2 and vascular endothelial growth factor-A. DesignTENAYA (NCT03823287) and LUCERNE (NCT03823300) were identically designed, randomized, double-masked, active comparator-controlled phase 3 noninferiority trials across 271 sites worldwide. ParticipantsTreatment-naïve patients with neovascular age-related macular degeneration (nAMD) aged ≥ 50 years. MethodsRandomized (1:1) to intravitreal faricimab 6.0 mg up to every 16 weeks (Q16W) or aflibercept 2.0 mg every 8 weeks (Q8W). Faricimab fixed dosing based on protocol-defined disease activity at weeks 20 and 24 up to week 60, followed up to week 108 by a treat-and-extend−based personalized treatment interval regimen. Main Outcome MeasuresEfficacy analyses included change in best-corrected visual acuity (BCVA) from baseline at 2 years (averaged over weeks 104, 108, and 112) and proportion of patients on Q16W, every 12 weeks (Q12W), and Q8W dosing at week 112 in the intention-to-treat population. Safety analyses included ocular adverse events (AEs) in the study eye through study end at week 112 in patients who received ≥ 1 dose of study treatment. ResultsOf 1326 patients treated across the trials, 1113 (83.9%) completed study treatment (n = 555 faricimab and n = 558 aflibercept). BCVA change from baseline at 2 years was comparable between faricimab and aflibercept in TENAYA (adjusted mean change [95% confidence interval (CI)] +3.7 letters [+2.1 to +5.4] and +3.3 letters [+1.7 to +4.9], respectively; mean difference [95% CI] 0.4 letters [−1.9 to +2.8]) and in LUCERNE (adjusted mean change [95% CI] +5.0 letters [+3.4 to +6.6] and +5.2 [+3.6 to +6.8], respectively; mean difference [95% CI] −0.2 letters [−2.4 to +2.1]). At week 112 in TENAYA and LUCERNE respectively, 59.0% and 66.9% achieved Q16W faricimab dosing, increasing from year 1, and 74.1% and 81.2% achieved ≥ Q12W dosing. Ocular AEs in the study eye were comparable between faricimab and aflibercept in TENAYA (55.0% and 56.5% of patients) and LUCERNE (52.9% and 47.5% of patients) through week 112. ConclusionsTreat-and-extend−based faricimab treatment based on nAMD disease activity maintained vision gains through year 2 with most patients achieving extended dosing intervals.

Efficacy and safety of enavogliflozin vs. dapagliflozin as add-on therapy in patients with type 2 diabetes mellitus based on renal function: a pooled analysis of two randomized controlled trials

BackgroundWe assessed the efficacy and safety of enavogliflozin (0.3 mg), a newly developed SGLT-2 inhibitor, in patients with type 2 diabetes mellitus based on kidney function via pooled analysis of two 24-week, randomized, double-blind phase III trials.MethodsData from 470 patients were included (enavogliflozin: 0.3 mg/day, n = 235; dapagliflozin: 10 mg/day, n = 235). The subjects were classified by mildly reduced (60 ≤ eGFR < 90 mL/min/1.73 m², n = 247) or normal eGFR (≥ 90 mL/min/1.73 m², n = 223).ResultsIn the mildly reduced eGFR group, enavogliflozin significantly reduced the adjusted mean change of HbA1c and fasting plasma glucose levels at week 24 compared to dapagliflozin (− 0.94% vs. −0.77%, P = 0.0196). Enavogliflozin exhibited a more pronounced glucose-lowering effect by HbA1c when combined with dipeptidyl peptidase-4 inhibitors than that observed in their absence. Enavogliflozin showed potent blood glucose-lowering effects regardless of renal function. Conversely, dapagliflozin showed a significant decrease in the glucose-lowering efficacy as the renal function decreased. Enavogliflozin showed a higher urinary glucose excretion rate in both groups. The homeostatic model assessment showed that enavogliflozin markedly decreased the insulin resistance. The blood pressure, weight loss, or homeostasis model assessment of beta-cell function values did not differ significantly between enavogliflozin and dapagliflozin. Adverse events were similar between both drugs.ConclusionsThe glucose-lowering efficacy of enavogliflozin is superior to that of dapagliflozin in patients with type 2 diabetes mellitus with mild renal function impairment; this is attributed to its potent urinary glucose excretion-promoting ability. The emergence of new and potent SGLT-2 inhibitors is considered an attractive option for patients with inadequate glycemic control and decreased renal function.Trial registrationNot applicable (pooled analysis).

Pioglitazone as Add-on Therapy in Patients with Type 2 Diabetes Mellitus Inadequately Controlled with Dapagliflozin and Metformin: Double-Blind, Randomized, Placebo-Controlled Trial.

This study assessed the efficacy and safety of triple therapy with pioglitazone 15 mg add-on versus placebo in patients with type 2 diabetes mellitus (T2DM) inadequately controlled with metformin and dapagliflozin. In this multicenter, double-blind, randomized, phase 3 study, patients with T2DM with an inadequate response to treatment with metformin (≥1,000 mg/day) plus dapagliflozin (10 mg/day) were randomized to receive additional pioglitazone 15 mg/day (n=125) or placebo (n=125) for 24 weeks. The primary endpoint was the change in glycosylated hemoglobin (HbA1c) levels from baseline to week 24 (ClinicalTrials.gov identifier: NCT05101135). At week 24, the adjusted mean change from baseline in HbA1c level compared with placebo was significantly greater with pioglitazone treatment (-0.47%; 95% confidence interval, -0.61 to -0.33; P<0.0001). A greater proportion of patients achieved HbA1c <7% or <6.5% at week 24 with pioglitazone compared to placebo as add-on to 10 mg dapagliflozin and metformin (56.8% vs. 28% for HbA1c <7%, and 23.2% vs. 9.6% for HbA1c <6.5%; P<0.0001 for all). The addition of pioglitazone also significantly improved triglyceride, highdensity lipoprotein cholesterol levels, and homeostatic model assessment of insulin resistance levels, while placebo did not. The incidence of treatment-emergent adverse events was similar between the groups, and the incidence of fluid retention-related side effects by pioglitazone was low (1.5%). Triple therapy with the addition of 15 mg/day of pioglitazone to dapagliflozin plus metformin was well tolerated and produced significant improvements in HbA1c in patients with T2DM inadequately controlled with dapagliflozin plus metformin.

Effectiveness of insulin degludec/liraglutide versus insulin degludec/insulin aspart in Japanese patients with type 2 diabetes.

To evaluate and compare the effectiveness of once-daily insulin degludec/liraglutide (IDegLira) to that of once-daily insulin degludec/insulin aspart (IDegAsp) after switching from basal insulin therapy at 6months by assessing changes in hemoglobin A1c (HbA1c), body weight, and insulin doses in patients with type 2 diabetes (T2D). A total of 91 patients with T2D with HbA1c levels exceeding 7.0% were included in this study. Adjusted least square mean changes in HbA1c, body weight, and total insulin doses were compared between the IDegLira group and IDegAsp group. Subgroup analyses were performed, stratified by median values of HbA1c (< 8.5 and ≥ 8.5%), obesity (body mass index < 25 and ≥ 25kg/m2), and basal insulin doses (< 14 and ≥ 14 units) at baseline to assess treatment interaction by subgroup. The IDegLira group showed a greater reduction in HbA1c levels than the IDegAsp group (-0.17 vs -0.79%, p = 0.003) with comparable body weight changes. The analyses of adjusted mean changes of total insulin doses showed that the IDegAsp group had a larger increase than the IDegLira group (3.64 vs 1.30 unis, p = 0.016). The effect of IDegLira on HbA1c levels was superior to that of IDegAsp in patients with high HbA1c. There were no inter-group differences in the rate of hypoglycemic episodes. Once-daily IDegLira had greater effects on HbA1c and a lesser increase in insulin doses than IDegAsp when patients are switched from basal insulin therapy. Moreover, the effect on HbA1c was enhanced in patients with high HbA1c levels at baseline.

One-year follow-up after active aortic aneurysm sac treatment with shape memory polymer devices during endovascular aneurysm repair

ObjectiveTo determine the safety and efficacy of treating abdominal aortic aneurysm (AAA) sacs with polyurethane shape memory polymer (SMP) devices during endovascular aneurysm repair (EVAR), using a technique to fully treat the target lumen after endograft placement (aortic flow volume minus the endograft volume). SMP devices self-expand in the sac to form a porous scaffold that supports thrombosis throughout its structure. MethodsTwo identical prospective, multicenter, single-arm studies were conducted in New Zealand and the Netherlands. The study population was adult candidates for elective EVAR of an infrarenal AAA (diameter of ≥55 mm in men and ≥50 mm in women). Key exclusion criteria were an inability to adequately seal a common iliac artery aneurysm, patent sac feeding vessels of >4 mm, and a target lumen volume of <20 mL or >135 mL. Target lumen volumes were estimated by subtracting endograft volumes from preprocedural imaging-based flow lumen volumes. SMP devices were delivered immediately after endograft deployment via a 6F sheath jailed in a bowed position in the sac. The primary efficacy end point was technical success, defined as filling the actual target lumen volume with fully expanded SMP at the completion of the procedure. Secondary efficacy outcome measures during follow-up were the change in sac volume and diameter, rate of type II endoleak and type I or III endoleaks, and the rate of open repair and related reinterventions, with data collection at 30 days, 6 months, and 1 year (to date). Baseline sac volumes and diameters for change in sac size analyses were determined from 30-day imaging studies. Baseline and follow-up volumes were normalized by subtraction of the endograft volume. ResultsOf 34 patients treated with SMP devices and followed per protocol, 33 patients were evaluable at 1 year. Preprocedural aneurysm volume was 181.4 mL (95% confidence interval [CI], 150.7-212.1 mL) and preprocedural aneurysm diameter was 60.8 mm (95% CI, 57.8-63.9 mm). The target lumen volume was 56.3 mL (95% CI, 46.9-65.8 mL). Technical success was 100% and the ratio of SMP fully expanded volume to estimated target lumen volume was 1.4 ± 0.3. Baseline normalized sac volume and diameter were 140.7 mL (95% CI, 126.6-154.9 mL) and 61.0 mm (95% CI, 59.7-62.3 mm). The adjusted mean percentage change in normalized volume at 1 year was −28.8% (95% CI, −35.3 to −22.3%; P < .001). The adjusted mean change in sac diameter at 1 year was −5.9 mm (95% CI, −7.5 to −4.4 mm; P < .001). At 1 year, 81.8% of patients (95% CI, 64.5%-93.0%) achieved a ≥10% decrease in normalized volume and 57.6% of patients (95% CI, 39.2%-74.5%) achieved a ≥5 mm decrease in diameter. No device- or study procedure-related major adverse events occurred through 1 year after the procedure. ConclusionsTreatment of AAA sacs with SMP devices during EVAR resulted in significant sac volume and diameter regression at 1 year with an acceptable safety profile in this prospective study.

Comparison of Efficacy between Pemafibrate and Omega-3-Acid Ethyl Ester in the Liver: the PORTRAIT Study.

No pharmacotherapeutic treatment has been established for metabolic dysfunction-associated steatotic liver disease (MASLD) and metabolic dysfunction-associated steatohepatitis (MASH). This trial compared the effects of pemafibrate and omega-3-acid ethyl ester on hepatic function in patients with hypertriglyceridemia complicated by MASLD. Patients with hypertriglyceridemia complicated by MASLD were enrolled, randomly assigned to the pemafibrate or omega-3-acid ethyl ester group, and followed for 24 weeks. The primary endpoint was the change in alanine aminotransferase (ALT) from baseline to week 24. The secondary endpoints included other hepatic enzymes, lipid profiles, and hepatic fibrosis biomarkers. A total of 80 patients were enrolled and randomized. The adjusted mean change in ALT from baseline to week 24 was significantly lower in the pemafibrate group (-19.7±5.9 U/L) than in the omega-3-acid ethyl ester group (6.8±5.5 U/L) (intergroup difference, -26.5 U/L; 95% confidence interval, -42.3 to -10.7 U/L; p=0.001). Pemafibrate significantly improved the levels of other hepatic enzymes (aspartate aminotransferase and gamma-glutamyl transpeptidase), lipid profiles (triglycerides, total cholesterol, high-density lipoprotein cholesterol, and non-high-density lipoprotein cholesterol), and hepatic fibrosis biomarkers (Mac-2 binding protein glycan isomer and Fibrosis-4 index). No cases of discontinuation due to adverse drug reactions were identified in either group, and there were no safety concerns. Pemafibrate is recommended over omega-3-acid ethyl ester for lipid management and MASLD treatment in patients with hypertriglyceridemia complicated by MASLD. The study results may contribute to the development of future treatment strategies for patients with MASLD/MASH.

Phase III study of bilayer sustained-release tramadol tablets in patients with cancer pain: a double-blind parallel-group, non-inferiority study with immediate-release tramadol capsules as an active comparator

PurposeWe investigated whether twice-daily administration of a bilayer tablet formulation of tramadol (35% immediate-release [IR] and 65% sustained-release) is as effective as four-times-daily IR tramadol capsules for managing cancer pain.MethodsThis randomized, double-blind, double-dummy, active-comparator, non-inferiority study enrolled opioid-naïve patients using non-steroidal anti-inflammatory drugs or acetaminophen (paracetamol) to manage cancer pain and self-reported pain (mean value over 3 days ≥ 25 mm on a 100-mm visual analog scale [VAS]). Patients were randomized to either bilayer tablets or IR capsules for 14 days. The starting dose was 100 mg/day and could be escalated to 300 mg/day. The primary endpoint was the change in VAS (averaged over 3 days) for pain at rest from baseline to end of treatment/discontinuation.ResultsOverall, 251 patients were randomized. The baseline mean VAS at rest was 47.67 mm (range: 25.6–82.7 mm). In the full analysis set, the adjusted mean change in VAS was − 22.07 and − 19.08 mm in the bilayer tablet (n = 124) and IR capsule (n = 120) groups, respectively. The adjusted mean difference was − 2.99 mm (95% confidence interval [CI] − 7.96 to 1.99 mm). The upper 95% CI was less than the predefined non-inferiority margin of 7.5 mm. Other efficacy outcomes were similar in both groups. Adverse events were reported for 97/126 (77.0%) and 101/125 (80.8%) patients in the bilayer tablet and IR capsule groups, respectively.ConclusionTwice-daily administration of bilayer tramadol tablets was as effective as four-times-daily administration of IR capsules regarding the improvement in pain VAS, with comparable safety outcomes.Clinical trial registrationJapicCTI-184143/jRCT2080224082 (October 5, 2018).

TANGO: a placebo-controlled randomized phase 2 study of efficacy and safety of the anti-tau monoclonal antibody gosuranemab in early Alzheimer’s disease

In Alzheimer’s disease, the spread of aberrantly phosphorylated tau is an important criterion in the Braak staging of disease severity and correlates with disease symptomatology. Here, we report the results of TANGO (NCT03352557), a randomized, double-blind, placebo-controlled, parallel-group and multiple-dose long-term trial of gosuranemab—a monoclonal antibody to N-terminal tau—in patients with early Alzheimer’s disease. The primary objective was to assess the safety and tolerability of gosuranemab compared to placebo. The secondary objectives were to assess the efficacy of multiple doses of gosuranemab in slowing cognitive and functional impairment (using the Clinical Dementia Rating Scale Sum of Boxes (CDR-SB) scores at week 78) and evaluate the immunogenicity of gosuranemab (using the incidence of anti-gosuranemab antibody responses). Participants were randomized (n = 654); received (n = 650) low-dose (125 mg once every 4 weeks (q4w), n = 58; 375 mg q12w, n = 58), intermediate-dose (600 mg q4w, n = 106) or high-dose (2,000 mg q4w, n = 214) gosuranemab or placebo (q4w, n = 214) intravenously for 78 weeks; and assigned to cerebrospinal fluid (n = 327) and/or tau positron emission tomography (n = 357) biomarker substudies. Gosuranemab had an acceptable safety profile and was generally well tolerated (incidence of serious adverse events: placebo, 12.1%; low dose, 10.3%; intermediate dose, 12.3%; high dose, 11.7%). The incidence of treatment-emergent gosuranemab antibody responses was low at all time points. No significant effects were identified in cognitive and functional tests as no dose resulted in a favorable change from the baseline CDR-SB score at week 78 compared to placebo control (adjusted mean change: placebo, 1.85; low dose, 2.20; intermediate dose, 2.24; high dose, 1.85). At week 76, all doses caused significant (P < 0.0001) reductions in the cerebrospinal fluid levels of unbound N-terminal tau compared to placebo.

Efficacy and safety of iscalimab, a novel anti-CD40 monoclonal antibody, in moderate-to-severe myasthenia gravis: A phase 2 randomized study

BackgroundIncreased morbidity in many patients with myasthenia gravis (MG) on long-term immunosuppression highlights the need for improved treatments.The aim of this study is to investigate the safety and efficacy of iscalimab (CFZ533), a fully human anti-CD40 monoclonal antibody, in patients with moderate-to-severe MG receiving standard-of-care (SoC) therapies. MethodsIn this double-blind, placebo-controlled phase 2 study, symptomatic patients (n = 44) despite SoC were randomized 1:1 to receive intravenous iscalimab (10 mg/kg; n = 22) or placebo (n = 22) every 4 weeks for 6 doses in total. Patients were followed up for 6 months after the last dose. The total duration of the study was 52 weeks. ResultsIn total, 34 of 44 patients (77.3 %) completed the study. The primary endpoint, Quantitative MG score, did not change significantly between baseline and week 25 for iscalimab (median [90 % CI], −4.07 [−5.67, −2.47]) versus placebo (−2.93 [−4.53, −1.33]); however, non-thymectomized patients (n = 29) showed more favorable results (iscalimab, −4.35 [−6.07, −2.64] vs placebo, −2.26 [−4.16, −0.36]). A statistically significant difference between iscalimab and placebo groups was observed in MG Composite score (adjusted mean change: −4.19 [−6.67, −1.72]; p = 0.007) at week 13, and MG-Activities of Daily Living score (−1.93 [−3.24, −0.62]; p = 0.018) at week 21. Adverse events were comparable between the iscalimab (91 %) and placebo (96 %) groups. ConclusionIscalimab showed favorable safety and improvements compared with placebo in non-thymectomized patients with moderate-to-severe MG. It did not show any protective effect in patients with moderate-to-severe MG.

Factor B Inhibition with Oral Iptacopan Monotherapy Demonstrates Sustained Long-Term Efficacy and Safety in Anti-C5-Treated Patients (pts) with Paroxysmal Nocturnal Hemoglobinuria (PNH) and Persistent Anemia: Final 48-Week Results from the Multicenter, Phase III APPLY-PNH Trial

Drs Roeth and Kulasekararaj contributed equally as authors. Background: Iptacopan is the first oral complement inhibitor that acts proximally in the complement system to target factor B in the alternative pathway. Iptacopan has shown efficacy/safety in PNH pts with persistent anemia despite anti-C5 therapy and complement inhibitor-naive pts. In the Phase III APPLY-PNH trial (NCT04558918), iptacopan monotherapy led to clinically meaningful hemoglobin (Hb) increases and normal/near-normal Hb levels in a majority of pts, transfusion avoidance and improved pt-reported fatigue, showing superiority vs C5 inhibitors at Week (Wk) 24. Aim: We report the final APPLY-PNH data after a 24-wk extension period in which all pts received iptacopan monotherapy (study completion: 6 March 2023). Methods: Adult PNH pts (mean Hb &amp;lt;10 g/dL, receiving anti-C5 therapy for ≥6 months) were randomized to receive iptacopan 200 mg twice daily or continue their anti-C5 regimen for 24 wks. Pts could then opt to enter an extension period; pts in the iptacopan arm received iptacopan for another 24 wks and pts who had been receiving anti-C5 switched to iptacopan monotherapy. Results: In the extension period, 95 pts received iptacopan: 61/62 in the iptacopan arm (1 discontinued iptacopan in the randomized period because of pregnancy) and 34/35 in the anti-C5-to-iptacopan arm (1 did not enter the extension period [investigator's decision]). In the iptacopan arm, the improvements at 24 wks were sustained at 48 wks, with maintenance of increased Hb, normal/near-normal mean Hb levels (Figure), improved Functional Assessment of Chronic Illness Therapy - Fatigue (FACIT-F) scores, decreased absolute reticulocyte counts (ARCs) and transfusion avoidance (Table). Pts who switched from anti-C5 to iptacopan had rapid changes in Hb, FACIT-F and ARC, achieving comparable improvements to the iptacopan arm. Mean Hb levels at Wk 48 were 12.2 and 12.1 g/dL in the iptacopan and anti-C5-to-iptacopan arms, respectively (standard deviations 1.6 and 1.4). At Wk 48, the adjusted mean change from baseline in the iptacopan arm was +3.35 g/dL for Hb, +9.80 FACIT-F points and −106.26 × 10 9/L for ARC. In the anti-C5-to-iptacopan arm, the adjusted mean change from baseline at Wk 48 was +3.36 g/dL for Hb, +10.96 FACIT-F points and −107.95 × 10 9/L for ARC (adjusted mean difference in change from baseline at Wk 48 vs Wk 24: +3.02 g/dL, +10.79 points and −102.29 × 10 9/L, respectively). Transfusion avoidance was achieved by 93.5% of pts in the iptacopan arm (Wks 2 to 48) and 94.1% in the anti-C5-to-iptacopan arm (Wks 26 to 48). Mean lactate dehydrogenase levels were generally maintained &amp;lt;1.5 × upper limit of normal in both arms. In the trial, 6/62 pts in the iptacopan arm had clinical breakthrough hemolysis (BTH). One pt in the anti-C5-to-iptacopan arm had clinical BTH after switching to iptacopan. BTH resolved without changing iptacopan dosing. Three pts had major adverse vascular events (MAVEs; randomized period: 1 serious transient ischemic attack [TIA]; extension period: 1 non-serious TIA, 1 serious portal vein thrombosis [PVT]). The pt with PVT had a history of PVT and discontinued heparin prior to the MAVE. All MAVEs were considered unrelated to iptacopan and resolved without changing iptacopan dosing. After 48 wks in the iptacopan arm, the most frequently reported treatment-emergent adverse events (TEAEs) were COVID-19 (29.0% of pts), headache (19.4%), diarrhea (16.1%) and nasopharyngitis (14.5%). There were no deaths, no serious hemolysis TEAEs on iptacopan, no serious infections caused by N. meningitidis, S. pneumoniae or H. influenzae and no pts discontinued treatment because of TEAEs. Conclusions: Long-term data from the Phase III APPLY-PNH trial show a durable response to iptacopan monotherapy in anti-C5-treated PNH pts with persistent anemia. Pts who received iptacopan for 48 wks had sustained improvements in multiple hematological and clinical outcomes, including maintenance of increased Hb, mean normal/near-normal Hb levels, transfusion avoidance and decreased pt-reported fatigue; these benefits quickly emerged in the anti-C5-to-iptacopan arm, supporting the benefit of switching from C5 inhibitors to iptacopan monotherapy. The data indicate good control of hemolysis by iptacopan and a similar safety profile at Wk 48 vs Wk 24. Our findings continue to support oral iptacopan monotherapy as a potentially practice-changing treatment for hemolytic PNH.

Comparison of BMI and HbA1c changes before and during the COVID-19 pandemic in type 1 diabetes: a longitudinal population-based study

PurposeTo compare the changes in body weight and glycemic control before and during the COVID-19 pandemic in people with type 1 diabetes (T1D).MethodsIn 47,065 individuals with T1D from the German Diabetes Prospective Follow-up Registry (DPV), we compared the adjusted mean changes in BMI-Z-scores and HbA1c as well as the distribution of individual changes between four periods from March 2018 to February 2022, by sex and age group (4- < 11, 11- < 16, 16–50 years).ResultsAt population level, the only significant pandemic effects were a slight increase in BMI Z-score in prepubertal children (girls: + 0.03 in the first COVID year vs. before, P < 0.01; boys: + 0.04, P < 0.01) as well as a stabilization of HbA1c in all subgroups or even improvement in women (− 0.08%, P < 0.01). At individual level, however, heterogeneity increased significantly (p < 0.01), especially in children. More prepubertal children gained weight (girls: 45% vs. 35% before COVID; boys: 39% vs. 33%). More pubertal girls lost weight (30% vs. 21%) and fewer gained weight (43% vs. 54%). More children had a decreasing HbA1c (prepubertal group: 29% vs. 22%; pubertal girls: 33% vs. 28%; pubertal boys: 32% vs. 25%) and fewer had increasing values. More women had stable HbA1c and fewer had increasing values (30% vs. 37%). In men, no significant changes were observed.ConclusionThis real-world analysis shows no detrimental consequences of the two first COVID years on weight and HbA1c in T1D on average, but reveals, beyond the mean trends, a greater variability at the individual level.

Dapagliflozin or Saxagliptin in Pediatric Type 2 Diabetes

BackgroundIncidence of type 2 diabetes (T2D) in children and adolescents is increasing, but treatment options are limited.MethodsThis was a 26-week, phase 3 trial with a 26-week extension among patients (10 to 17 years of age) with uncontrolled T2D (A1C 6.5 to 10.5%) receiving metformin, insulin, or both. Participants were randomly assigned 1:1:1 to 5 mg of dapagliflozin (N=81), 2.5 mg of saxagliptin (N=88), or placebo (N=76). Patients in active treatment groups with A1C ≥7% at week 12 were further randomly assigned 1:1 at week 14 to continue the dose or up-titrate to a higher dose (10 mg of dapagliflozin or 5 mg of saxagliptin). The primary end point was change in A1C at week 26. Safety was assessed over 52 weeks.ResultsAt week 26, the difference versus placebo in adjusted mean change in A1C was −1.03 percentage points (95% confidence interval [CI], −1.57 to −0.49; P<0.001) for dapagliflozin and −0.44 percentage points (95% CI, −0.93 to 0.05; P=0.078) for saxagliptin. Adverse events (AEs) and serious AEs occurred in 72.8% and 8.6% of patients receiving dapagliflozin, 69.3% and 8.0% of patients receiving saxagliptin, and 71.1% and 6.6% of patients receiving placebo. Severe hypoglycemia occurred in 4.9%, 4.5%, and 7.9% of patients in each group, respectively. Over 52 weeks, the most common AE was headache (dapagliflozin 14.8%; placebo 5.3%). Most events were mild and none was considered serious or resulted in discontinuation.ConclusionsDapagliflozin, but not saxagliptin, showed significant improvement in A1C compared with placebo. Nonserious headaches were more common in participants treated with dapagliflozin than in those receiving placebo. (Funded by AstraZeneca; ClinicalTrials.gov number, NCT03199053.)

Lecanemab Clarity AD: Quality-of-Life Results from a Randomized, Double-Blind Phase 3 Trial in Early Alzheimer’s Disease

BackgroundLecanemab is a humanized IgG1 monoclonal antibody binding with high affinity to amyloid-beta protein protofibrils. In phase 3 development, lecanemab has been shown to reduce markers of amyloid in early Alzheimer’s disease and reduce decline on clinical endpoints of cognition and function at 18 months.ObjectivesTo describe the health-related quality-of-life (HRQoL) results from Clarity AD which were exploratory outcomes in this trial.DesignClarity AD was an 18-month, multi-center, doubleblind, phase 3 trial.SettingEarly Alzheimer’s disease.ParticipantsIndividuals 50–90 years of age with a diagnosis of mild cognitive impairment or mild dementia due to Alzheimer’s disease and positron emission tomography or cerebrospinal fluid evidence of cerebral amyloid accumulation.InterventionPlacebo or lecanemab 10-mg/kg IV biweekly.MeasurementsHRQoL was measured at baseline and every 6 months using the European Quality of Life–5 Dimensions (EQ-5D-5L; by subject) and Quality of Life in AD (QOL-AD; by subject and proxy). Study partner burden was measured using the Zarit Burden Interview (ZBI).ResultsA total of 1795 participants were enrolled (lecanemab:898; placebo:897). At month 18, adjusted mean change from baseline in EQ-5D-5L and QOL-AD by subject showed 49% and 56% less decline, respectively. QOL-AD rated by study partner as proxy resulted in 23% less decline. ZBI adjusted mean change from baseline at 18 months resulted in 38% less increase of care partner burden. Individual HRQoL test items and dimensions also showed lecanemab benefit.ConclusionsLecanemab was associated with a relative preservation of HRQoL and less increase in caregiver burden, with consistent benefits seen across different quality of life scales and within scale subdomains. These benefits provide valuable patient reported outcomes which, together with previously reported benefits of lecanemab across multiple measures of cognition, function, disease progression, and biomarkers, demonstrate that lecanemab treatment may offer meaningful benefits to patients, care partners, and society.

Midwife or doctor leader to implement a national guideline in babies on postnatal wards (DesIGN): A cluster-randomised, controlled, trial.

The aim of this trial was to determine if midwives or doctor leaders are more effective at implementing a clinical practice guideline for oral dextrose gel to treat neonatal hypoglycaemia. This was a cluster-randomised, controlled, trial. New Zealand maternity hospitals were randomised to guideline implementation by a midwife or doctor implementation leader. The primary outcome was the change in the proportion of hypoglycaemic babies (blood glucose concentration <2.6 mmol/L in the first 48 hours after birth), treated with dextrose gel from before, to three months after, implementation. Twenty-one maternity hospitals that cared for babies at risk of hypoglycaemia consented to participate, of which 15 treated babies with hypoglycaemia at both time points (7 randomised to midwifery led, 8 randomised to doctor led implementation). The primary outcome included 463 hypoglycaemic babies (292 midwifery led, 171 doctor led implementation). There was no difference in the primary outcome between hospitals randomised to midwifery or doctor led implementation (proportion treated with gel, mean(SD); midwifery led: before 71 (38)%, 3 months after 87 (12)%; doctor led: before 63 (43)%, 3 months after 86 (16)%; adjusted mean change in proportion (95%CI); 19.3% (-4.5-43.1), p = 0.11). There was an increase in the proportion of eligible babies treated with oral dextrose gel from before to 3 months after implementation of the guideline (122/153 (80%) v 144/163 (88%), OR (95%CI); 3.42 (1.67-6.98), p<0.001). Implementation of a clinical practice guideline improved uptake of oral dextrose gel. There was no evidence of a difference between midwife and doctor implementation leaders for implementing this guideline for treatment of hypoglycaemic babies. The trial was prospectively registered on the ISRCTN registry on the 20/05/2015 (ISRCTN61154098).

Eplontersen for Hereditary Transthyretin Amyloidosis With Polyneuropathy

Transthyretin gene silencing is an emerging treatment strategy for hereditary transthyretin (ATTRv) amyloidosis. To evaluate eplontersen, an investigational ligand-conjugated antisense oligonucleotide, in ATTRv polyneuropathy. NEURO-TTRansform was an open-label, single-group, phase 3 trial conducted at 40 sites across 15 countries (December 2019-April 2023) in 168 adults with Coutinho stage 1 or 2 ATTRv polyneuropathy, Neuropathy Impairment Score 10-130, and a documented TTR variant. Patients treated with placebo from NEURO-TTR (NCT01737398; March 2013-November 2017), an inotersen trial with similar eligibility criteria and end points, served as a historical placebo ("placebo") group. Subcutaneous eplontersen (45 mg every 4 weeks; n = 144); a small reference group received subcutaneous inotersen (300 mg weekly; n = 24); subcutaneous placebo weekly (in NEURO-TTR; n = 60). Primary efficacy end points at week 65/66 were changes from baseline in serum transthyretin concentration, modified Neuropathy Impairment Score +7 (mNIS+7) composite score (scoring range, -22.3 to 346.3; higher scores indicate poorer function), and Norfolk Quality of Life Questionnaire-Diabetic Neuropathy (Norfolk QoL-DN) total score (scoring range, -4 to 136; higher scores indicate poorer quality of life). Analyses of efficacy end points were based on a mixed-effects model with repeated measures adjusted by propensity score weights. Among 144 eplontersen-treated patients (mean age, 53.0 years; 69% male), 136 (94.4%) completed week-66 follow-up; among 60 placebo patients (mean age, 59.5 years; 68% male), 52 (86.7%) completed week-66 follow-up. At week 65, adjusted mean percentage reduction in serum transthyretin was -81.7% with eplontersen and -11.2% with placebo (difference, -70.4% [95% CI, -75.2% to -65.7%]; P < .001). Adjusted mean change from baseline to week 66 was lower (better) with eplontersen vs placebo for mNIS+7 composite score (0.3 vs 25.1; difference, -24.8 [95% CI, -31.0 to -18.6; P < .001) and for Norfolk QoL-DN (-5.5 vs 14.2; difference, -19.7 [95% CI, -25.6 to -13.8]; P < .001). Adverse events by week 66 that led to study drug discontinuation occurred in 6 patients (4%) in the eplontersen group vs 2 (3%) in the placebo group. Through week 66, there were 2 deaths in the eplontersen group consistent with known disease-related sequelae (cardiac arrhythmia; intracerebral hemorrhage); there were no deaths in the placebo group. In patients with ATTRv polyneuropathy, the eplontersen treatment group demonstrated changes consistent with significantly lowered serum transthyretin concentration, less neuropathy impairment, and better quality of life compared with a historical placebo.

Defocus incorporated multiple segments (DIMS) spectacle lenses increase the choroidal thickness: a two-year randomized clinical trial

BackgroundMyopia control interventions, such as defocus incorporated multiple segments (DIMS) spectacle lenses, have been adopted in school-aged children to reduce the prevalence of myopia and its complications. This study aimed to investigate the effect of DIMS spectacle lenses on subfoveal choroidal thickness (SfChT) over a period of two years, as the choroidal response to myopic control is a crucial factor in exploring its potential effect on predicting myopia progression.MethodsThis study involved a secondary analysis of our previous randomized clinical trial. Myopic school-aged children aged 8–13 years were recruited in a two-year study investigating the effect of DIMS spectacle lenses on myopia progression. The treated group received DIMS spectacle lenses (n = 78), while the control group was treated with a pair of single vision (SV) spectacle lenses (n = 80). SfChT was monitored at 1 week, 1, 3, 6, 12, 18 and 24 months post lens wear using spectral-domain optical coherence tomography and a custom made auto-segmentation algorithm utilizing convolutional neural networks.ResultsSfChT increased significantly after one week of DIMS spectacle lens wear compared to those wearing SV spectacle lenses (adjusted mean change relative to baseline ± SEM at one week; DIMS vs. SV, 6.75 ± 1.52 µm vs. − 3.17 ± 1.48 µm; P < 0.0001, general linear model). The thickness of choroid increased to 13.64 ± 2.62 µm after 12 months of DIMS lens wear while the choroid thinned in SV group (− 9.46 ± 2.55 µm). Choroidal changes demonstrated a significant negative association with axial elongation over two years in both the DIMS and SV groups. Choroidal change at three months significantly predicted the changes in AL at 12 months after controlling the effect of age and gender.ConclusionsOur study demonstrated a significant choroidal thickening in response to myopic defocus incorporated in a spectacle lens after one week of lens wear, sustained over the two-year study period. The results suggested that choroidal changes at three months may help predict changes in axial length after one year.Trial registration ClinicalTrials.gov. Myopia control with the multi-segment lens.

Left ventricular remodeling and its correlates among adolescents with perinatally acquired HIV in South Africa

BackgroundLeft ventricular (LV) remodeling and its transitions from compensatory adaptations to LV dysfunction have not been examined in adolescents with perinatally acquired HIV infection (PHIV). We used cardiovascular magnetic resonance (CMR) in a cross-sectional study to characterize PHIV-related progressive LV remodeling in adolescents in South Africa. MethodsAdolescents with PHIV on antiretroviral treatment and their HIV uninfected peers completed 3 T CMR examination. We defined LV remodeling by LV mass/volume (M/V) ratio, modelling progressive LV remodeling as increasing M/V ratio. Linear regression models were applied to estimate the correlates of progressive LV remodeling. ResultsOverall, 71 adolescents with PHIV [mean age: 15.2 years; 54% male] and 36 HIV uninfected [15.1 years; 42% male] peers were enrolled. Adolescents with PHIV had lower mean LV M/V ratio (0.68 vs. 0.75 g/mL; p = 0.004) than HIV uninfected peers, without LV hypertrophy in either group. Among adolescents with PHIV, increasing M/V ratio was accompanied by increasing interstitial volume [adjusted mean change (AMC) per 0.1 g/mL M/V ratio: 1.75 mL, p < 0.001] with no change in global circumferential strain (GCS) [AMC per 0.1 g/mL M/V ratio: −0.21%, p = 0.48]. However, in HIV uninfected individuals, increasing M/V ratio was accompanied by increasing peak GCS [AMC per 0.1 g/mL M/V ratio: −1.25%, p = 0.039] with no change in interstitial volume (AMC per 0.1 g/mL M/V ratio: 1.16 mL, p = 0.32]. ConclusionsSuccessfully treated PHIV is associated with less severe LV remodeling in adolescence when compared to HIV uninfected controls. LV remodeling in PHIV is associated with disproportionate expansion of the non-contractile interstitium not accompanied by improved GCS.

Two-year outcomes of temperature-controlled radiofrequency device treatment of the nasal valve for patients with nasal airway obstruction.

The objective of this study was to evaluate long-term symptom improvements in patients with nasal airway obstruction (NAO) secondary to nasal valve collapse (NVC) following minimally invasive temperature-controlled radiofrequency (TCRF) treatment. A prospective, single-arm, multicenter study in patients >18 years with NAO due to NVC. Inclusion criteria were response to nasal valve dilation (e.g., modified Cottle maneuver) and baseline Nasal Obstruction Symptom Evaluation (NOSE) Scale score ≥60. Patients were treated in the nasal valve region with a TCRF device and followed through 2 years. A responder was ≥20% reduction NOSE Scale score or ≥1 reduction in severity class. A total of 122 patients were treated and 91 reached 2 years. The mean baseline NOSE Scale score was 80.3 (95% CI, 78.1-82.6). The adjusted mean change in score at 2 years was -45.8 (95% CI, -53.5 to -38.1), p < 0.001; a 57.0% improvement. The 2-year responder rate was 90.1% (95% CI, 82.3%-94.7%). Significant and sustained symptom improvement was achieved in subpopulations based on sex, age, body mass index, baseline NAO severity, nasal surgery history, NVC mechanism, septal deviation, and other anatomic contributors of NAO. No serious adverse events with a relationship to the study device and/or procedure were reported. Minimally invasive TCRF device treatment of the internal nasal valve for NAO is well tolerated and leads to significant and sustained improvement in NAO symptom severity through 2 years, including in patients with both static and dynamic NVC, septal deviation, turbinate enlargement, or prior nasal surgery. 2b.

Antenatal mobile-delivered mindfulness-based intervention to reduce perinatal depression risk and improve obstetric and neonatal outcomes: A randomized controlled trial

ObjectivesOne in five mothers will experience perinatal depression (PND) during pregnancy and within their first year following childbirth. Current evidence suggests the short-term efficacy of Mindfulness-based interventions (MBI) for perinatal women, but the extent to which this positive impact remains the early postpartum period is unclear. This study investigated the short- and maintenance efficacy of a mobile-delivered four-immeasurable MBI on PND, and obstetric and neonatal outcomes. MethodsSeventy-five adult pregnant women suffering from heightened distress were randomized to receive a mobile-delivered four-immeasurable MBI (n = 38) or a web-based perinatal education program (n = 37). PND was measured by Edinburgh Postnatal Depression Scale at baseline, post-intervention, 37th-week gestation, and 4–6 weeks postpartum. Outcomes also included obstetric and neonatal outcomes, trait mindfulness, self-compassion, and positive affect. ResultsParticipants reported an average age of 30.6 (SD = 3.1) years with a mean gestational age of 18.8 (SD = 4.6) weeks. In intention-to-treat analyses, women in the mindfulness group showed a significantly greater reduction in depression from baseline to post-intervention (adjusted mean change difference [β] = −3.9; 95%CI = [−6.05, −1.81]; d = −0.6), and the reduction sustained until 4–6 weeks postpartum (β = −6.3; 95%CI = [−8.43, −4.12]; d = −1.0), compared with control. They had a significantly reduced risk of emergent cesarean section (relative risk = 0.5) and gave birth to infants with higher Apgar scores (β = 0.6;p = .03; d = 0.7). Depression reduction before giving birth significantly mediated the intervention effect on lowering the emergency cesarean risk. ConclusionsWith a reasonably low dropout rate (13.2 %), the mobile-delivered MBI can be an acceptable and effective intervention for reducing depression throughout pregnancy and postpartum. Our study also suggests the potential benefits of early prevention for mitigating emergent cesarean section risk and enhancing neonatal health.

Impact of Ambulatory Care Pharmacist-Led Management on Hemoglobin A1c Values among Patients with Uncontrolled Diabetes in a Primary Care Clinic vs Usual Care over Two Years.

Background: Literature has shown the positive impact of ambulatory care pharmacists on diabetes management, yet additional research on clinical outcomes compared to traditional care models is warranted. Objective: The objective of this study is to evaluate the impact of an ambulatory care pharmacist on glycemic control over two years compared to patients who received usual care. Methods: This retrospective cohort study matched patients with a baseline hemoglobin A1c (HgbA1c) ≥8% managed by the ambulatory care pharmacist to patients who received usual care. The primary outcome was the mean change in HgbA1c over two years. The secondary outcomes were to evaluate the difference in (1) the proportion of patients achieving HgbA1c <8%, (2) the proportion of patients achieving blood pressure <130/80mmHg, (3) mean LDL, (4) the proportion of patients prescribed SGLT2 inhibitors, GLP-1RA, and sulfonylureas, and (5) severe hypoglycemia after two years. Results: Data for 180 patients was analyzed over two years. The mean HgbA1c was 10% at baseline vs 8.2% after two years (adjusted mean change -1.92) among pharmacist-managed patients, compared to 9.9% vs 9% respectively for usual care patients (adjusted mean change -0.98) (p=0.004). Among pharmacist-managed patients, 53.5% achieved HgbA1c <8% compared with 34.2% of usual care patients (p=0.014). There were no statistically significant differences in proportion of patients at goal blood pressure, mean LDL, or hypoglycemia between the two groups. After two years, 18.3% of pharmacist-managed and 5.8% of usual care patients were on an SGLT2 inhibitor (p=0.008), and 46.7% of pharmacist-managed and 9.2% of usual care patients were on a GLP-1RA (p<0.001). No difference was found in sulfonylurea utilization. Conclusion: Patients with HgbA1c >8% managed by an ambulatory care pharmacist had twice the HgbA1c reduction and significantly more utilization of GLP-1RA and SGLT2 inhibitors as compared to controls provided usual care.
