Dupilumab in Adults With Moderate to Severe Atopic Dermatitis

Moderate to severe atopic dermatitis (AD) is a chronic inflammatory skin disease that often requires continuous long-term systemic management. Long-term safety and efficacy data for treatment options are critically important. To assess the safety and efficacy of dupilumab treatment for up to 5 years in adults with moderate to severe AD. The 5-year LIBERTY AD open-label extension study was conducted from September 2013 to June 2022 at 550 sites in 28 countries. The study enrolled adult patients with moderate to severe AD who had participated in previous dupilumab clinical trials. Data were analyzed from August 2022 to February 2023. At enrollment, patients initiated a regimen of subcutaneous dupilumab, 200 mg, weekly (400-mg loading dose). The regimen was amended in June 2014 to dupilumab, 300 mg, weekly (600-mg loading dose) based on a dose-ranging study and again in November 2019 to dupilumab, 300 mg, every 2 weeks to align with the regulatory regimen approvals. The primary end points were the incidence and rate of treatment-emergent adverse events (TEAEs). Key secondary end points included incidence and rate of serious TEAEs and adverse events of special interest, proportion of patients achieving an Investigator's Global Assessment (IGA) score of 0 or 1 (clear or almost clear), and proportion of patients with 75% or more improvement in the Eczema Area and Severity Index (EASI) from the parent study baseline. A total of 2677 patients were enrolled and treated in the open-label extension study; 1611 (60.2%) were male, and the mean (SD) age was 39.2 (13.4) years. A total of 334 patients (12.5%) completed treatment up to week 260. The most common reasons for withdrawal were due to regulatory approval of dupilumab in compliance with the study protocol (810 of 1380 [58.7%]), patient withdrawal (248 of 1380 [18.0%]), and adverse events (116 of 1380 [8.4%]). Exposure-adjusted rates of TEAEs were generally stable or declined throughout the study. Common TEAEs (incidence of 5% or greater) included nasopharyngitis, worsening AD, upper respiratory tract infection, conjunctivitis, conjunctivitis allergic, headache, oral herpes, and injection-site reaction. At week 260, 220 of 326 patients (67.5%) achieved an IGA score of 0 or 1 and 288 of 324 (88.9%) achieved 75% or greater improvement in the EASI. The mean (SD) EASI score was 16.39 (14.60) at baseline and 2.75 (5.62) at end of study. In this study, there was sustained safety and efficacy of continuous long-term dupilumab treatment for adults with moderate to severe AD.

Total neoadjuvant therapy with mFOLFIRINOX versus preoperative chemoradiotherapy in patients with locally advanced rectal cancer: long-term results of the UNICANCER-PRODIGE 23 trial

The standard of care for the treatment of locally advanced rectal cancer (LARC) results in an excellent local disease control but the metastasis rates remain high. PRODIGE 23 demonstrated improved disease-free survival (DFS) and metastasis-free survival (MFS) with total neoadjuvant therapy versus standard of care in this population. Long-term analysis of overall survival (OS) is reported here. The study design, participants, and primary endpoint DFS have been reported for this multicenter, randomized, open-label, phase III trial investigating the neoadjuvant chemotherapy with mFOLFIRINOX (6 cycles) followed by chemoradiotherapy, surgery, and adjuvant chemotherapy (6 cycles), versus chemoradiotherapy, surgery, and adjuvant chemotherapy (12 cycles) in patients with locally advanced rectal adenocarcinoma under peritoneal reflection on magnetic resonance imaging, and staged cT3/T4. Key secondary endpoints included OS, MFS, and local and metastatic recurrence rate. With a median follow-up of 82.2 months, the 7-year DFS was 67.6% [95% confidence interval (CI) 60.7% to 73.9%] and 62.5% (95% CI 55.6% to 68.6%) [restricted mean survival time (RMST) difference 5.73 months, 95% CI 0.05-11.41 months, P= 0.048] in the neoadjuvant chemotherapy and the standard-of-care groups, respectively. The 7-year MFS was 79.2% (95% CI 73.0% to 84.4%) in the neoadjuvant chemotherapy group and 72.3% (95% CI 65.8% to 77.8%) in the standard-of-care group (RMST difference 6.1 months, 95% CI 0.93-11.37 months, P= 0.021). The 7-year OS was 81.9% (95% CI 75.8% to 86.6%) in the neoadjuvant chemotherapy group and 76.1% (95% CI 69.7% to 81.2%) in the standard-of-care group (RMST difference 4.37 months, 95% CI 0.35-8.38 months, P= 0.033). The safety profile remained unchanged since the previous analysis. Neoadjuvant chemotherapy with mFOLFIRINOX followed by chemoradiotherapy improved OS, confirmed long-term DFS and MFS benefits in LARC patients, and should be considered as one of the best options of care for these patients.

Preclinical study and phase II trial of adapting low-dose radiotherapy to immunotherapy in small cell lung cancer

Immune checkpoint inhibitors (ICIs) provide modest but unsatisfactory benefits for extensive-stage small cell lung cancer (ES-SCLC). Developing strategies for treating ES-SCLC is critical. We preliminarily explored the outcomes of salvage low-dose radiotherapy (LDRT) plus ICI on refractory SCLC patients. Next, we evaluated the combinational efficacy in murine SCLC. The tumor immune microenvironment (TIME) was analyzed for mechanistic study. Subsequently, we conducted a multicenter, prospective phase II trial that administered concurrent thoracic LDRT plus chemoimmunotherapy to treatment-naive ES-SCLC patients (MATCH trial, NCT04622228). The primary endpoint was confirmed objective response rate (ORR), and the key secondary endpoints included progression-free survival (PFS) and safety. Fifteen refractory SCLC patients treated with LDRT plus ICI were retrospectively reviewed. The ORR was 73.3% (95% confidence interval [CI], 44.9-92.2). We identified a specific dose of LDRT (15 Gy/5 fractions) that exhibited growth retardation and improved survival in murine SCLC when combined with ICIs. This combination recruited a special Tcell population, TCF1+ PD-1+ CD8+ stem-like Tcells, from tumor-draining lymph nodes into the TIME. The MATCH trial showed a confirmed ORR of 87.5% (95% CI, 75.9-94.8). The median PFS was 6.9months (95% CI, 5.4-9.3). These findings verified that LDRT plus chemoimmunotherapy was safe, feasible, and effective for ES-SCLC, warranting further investigation. This research was funded by West China Hospital (no. ZYJC21003), the National Natural Science Foundation of China (no. 82073336), and the MATCH trial was fully funded by Roche (China) Holding Ltd. (RCHL) and Shanghai Roche Pharmaceuticals Ltd. (SRPL).

Neoadjuvant short-course radiotherapy followed by camrelizumab and chemotherapy in locally advanced rectal cancer (UNION): early outcomes of a multicenter randomized phase III trial

Neoadjuvant short-course radiotherapy (SCRT) followed by CAPOX and camrelizumab (a programmed cell death protein 1 monoclonal antibody) has shown potential clinical activity for locally advanced rectal cancer (LARC) in a phase II trial. This study aimed to further confirm the efficacy and safety of SCRT followed by CAPOX and camrelizumab compared to long-course chemoradiotherapy (LCRT) followed by CAPOX alone as neoadjuvant treatment for LARC. In this randomized, phase III trial, patients with T3-4/N+ rectal adenocarcinoma were randomly assigned (1 : 1) to receive SCRT or long-course chemoradiotherapy (LCRT), followed by two cycles of camrelizumab and CAPOX or CAPOX alone, respectively. After surgery, each arm underwent either six cycles of camrelizumab and CAPOX, followed by up to 17 doses of camrelizumab, or six cycles of CAPOX. The primary endpoint was pathological complete response (pCR) rate (ypT0N0) assessed by a blinded independent review committee. Key secondary endpoints tested hierarchically were 3-year event-free survival (EFS) rate and overall survival (OS). Between July 2021 and March 2023, the intention-to-treat population comprised 113 patients in the experimental arm and 118 patients in the control arm, with surgery carried out in 92% and 83.9%, respectively. At data cut-off (11 July 2023), the pCR rates were 39.8% [95% confidence interval (CI) 30.7% to 49.5%] in the experimental arm compared to 15.3% (95% CI 9.3% to 23.0%) in the control arm (difference, 24.6%; odds ratio, 3.7; 95% CI 2.0-6.9; P < 0.001). In each arm, surgical complication rates were 40.0% and 40.8%, and grade ≥3 treatment-related adverse events were 29.2% and 27.2%. Three-year EFS rate and OS continue to mature. In LARC patients, neoadjuvant SCRT followed by camrelizumab plus CAPOX demonstrated a significantly higher pCR rate than LCRT followed by CAPOX, with a well-tolerated safety profile. SCRT followed by camrelizumab and chemotherapy can be recommended as a neoadjuvant treatment modality for these patients.

Efficacy and safety of Tianqi Pingchan Granule, a compound Chinese herbal medicine, for levodopa-induced dyskinesia in Parkinson’s disease: A randomized double-blind placebo-controlled trial

BackgroundPatients with Parkinson’s disease (PD) undergoing long-term levodopa therapy are prone to develop levodopa-induced dyskinesia (LID). Amantadine is the main drug recommended for the treatment of LID by current guidelines, but it is far from meeting clinical needs. Tianqi Pingchan Granule (TPG), a compound Chinese herbal medicine, has been developed to relieve symptom of LID. ObjectiveThis randomized controlled trial evaluated the efficacy and safety of the combination of TPG and amantadine for LID. Design, setting, participants and interventionsThis is a randomized double-blind placebo-controlled trial, conducted from January 2020 to August 2021 at 6 sites in Jiangsu, Zhejiang and Shanghai, China. One hundred PD patients with ≥ 0.5 h of LID were randomly assigned to either the TPG plus amantadine group (TPG group) or the placebo plus amantadine group (placebo group), and treated for a period of 12 weeks. To ensure unbiased results, all study participants, investigators and sponsors were unaware of group allocations. Additionally, the data analysts remained blinded until the analysis was finalized. Main outcome measuresThe primary outcome was assessed using the Unified Dyskinesia Rating Scale (UDysRS) (Range 0–104). The key secondary end point was improvement of motor and non-motor symptoms. Safety analyses included all enrolled patients. ResultsOne hundred patients were enrolled and randomized into the two treatment groups. The changes in UDysRS at week 12 were –11.02 for the TPG group and –4.19 for the placebo group (treatment difference –6.83 [–10.53 to –3.12]; P = 0.0004). Adverse events were reported for 2 of 50 patients (4.0%) in each of the groups. ConclusionThis study indicated that a 12-week treatment of amantadine plus TPG effectively reduced UDysRS scores and was well tolerated, demonstrating the efficacy and safety of TPG for the treatment of LID in PD.Trial registration: ClinicalTrials.gov identifier: NCT04173832.

Efficacy and safety of topical minocycline foam (FMX101 4%) in treatment of Chinese subjects with moderate‐to‐severe facial acne vulgaris: A phase 3, multi‐centre, randomized, double‐blind, vehicle‐controlled study

AbstractBackgroundFMX101 4%, as a topical foam formulation of minocycline, has been approved by US Food and Drug Administration for the treatment of moderate‐to‐severe acne vulgaris (AV).ObjectiveTo evaluate the efficacy and safety of FMX101 4% in treating Chinese subjects with moderate‐to‐severe facial AV.MethodsThis was a multi‐centre, randomized, double‐blind, vehicle‐controlled phase 3 study in Chinese subjects with moderate‐to‐severe AV. Eligible subjects were randomized 2:1 to receive either FMX101 4% or vehicle foam treatment for 12 weeks. The primary efficacy endpoint was the change in inflammation lesion count (ILC) from baseline at week 12. The key secondary endpoint was the treatment success rate according to Investigator's Global Assessment (IGA) at week 12.ResultsIn total, 372 subjects were randomized into two groups (FMX101 4% group, n = 248; vehicle group, n = 124). After 12 weeks treatment, the reduction in ILC from baseline was statistically significant in favour of FMX101 4%, compared with vehicle foam (−21.0 [0.08] vs. −12.3 [1.14]; LSM [SE] difference, −8.7 [1.34]; 95% CI [−11.3, −6.0]; p &lt; 0.001). FMX101 4% treatment yielded significantly higher IGA treatment success rate at week 12 as compared to the control treatment (8.06% vs. 0%). Applying FMX101 4% also resulted in significant reduction in noninflammatory lesion count (nILC) versus vehicle foam at week 12 (−19.4 [1.03] vs. −14.9 [1.47]; LSM [SE] difference, −4.5 [1.74]; 95% CI [−8.0, −1.1]; p = 0.009). Most treatment‐emergent adverse events (TEAEs) were mild‐to‐moderate in severity, and no treatment‐related treatment‐emergent serious adverse event (TESAE) occurred. Thus, FMX101 4% was considered to be a safe and well‐tolerated product during the 12‐week treatment period.ConclusionFMX101 4% treatment for 12 weeks could lead to significantly reduced ILC and nILC, and improved IGA treatment success rate in Chinese subjects with moderate‐to‐severe facial AV. It also showed a well acceptable safe and tolerability profile.

Nemolizumab with concomitant topical therapy in adolescents and adults with moderate-to-severe atopic dermatitis (ARCADIA 1 and ARCADIA 2): results from two replicate, double-blind, randomised controlled phase 3 trials

Nemolizumab, an interleukin (IL)-31 receptor subunit α antagonist, inhibits the IL-31 pathway of itch and skin inflammation in atopic dermatitis. Two international phase 3 studies were done to assess the efficacy and safety of nemolizumab in atopic dermatitis. In this Article we report results for the 16-week initial treatment period of both trials. ARCADIA 1 and ARCADIA 2 were identical 48-week randomised, double-blind, placebo-controlled phase 3 trials in adult and adolescent participants (aged ≥12 years) with moderate-to-severe atopic dermatitis, associated pruritus, and inadequate response to topical steroids. Participants were enrolled from 281 clinics, hospitals, and academic centres in 22 countries across both trials, and were randomly assigned (2:1) to receive nemolizumab 30 mg subcutaneously (baseline loading dose 60 mg) or matching placebo once every 4 weeks with background topical corticosteroids (TCS) with or without topical calcineurin inhibitors (TCI; ie, TCS-TCI background treatment). Randomisation was done via interactive response technology and stratified by baseline disease and pruritus severity. Study staff and participants were masked throughout the study, with outcome assessors masked until database lock. Coprimary endpoints at week 16 post-baseline were Investigator's Global Assessment (IGA) success (score of 0 [clear skin] or 1 [almost clear skin] with a ≥2-point improvement from baseline) and at least 75% improvement in Eczema Area and Severity Index score from baseline (EASI-75 response). Outcome rates were compared between groups with the Cochran-Mantel-Haenszel test adjusting for randomisation strata. The key secondary endpoints were the proportion of participants with Peak Pruritus Numerical Rating Scale (PP-NRS) score improvement of at least 4 points at weeks 1, 2, 4, and 16; PP-NRS score below 2 at weeks 4 and 16; Sleep Disturbance Numerical Rating Scale score improvement of at least 4 points at week 16; EASI-75 response plus PP-NRS score improvement of at least 4 points at week 16; and IGA success plus PP-NRS score improvement of at least 4 points at week 16. Efficacy analyses were done on an intention-to-treat basis; safety analyses included all participants who received one dose of nemolizumab or placebo. Both studies are completed (ClinicalTrials.gov: ARCADIA 1, NCT03985943 and ARCADIA 2, NCT03989349). Between Aug 9, 2019, and Nov 2, 2022, 1728 participants were enrolled across both trials: 1142 were allocated to nemolizumab plus TCS-TCI (620 in ARCADIA 1 and 522 in ARCADIA 2) and 586 to placebo plus TCS-TCI (321 in ARCADIA 1 and 265 in ARCADIA 2). ARCADIA 1 included 500 (53%) male participants and 441 (47%) female participants, and ARCADIA 2 included 381 (48%) male participants and 406 (52%) female participants. Mean age ranged from 33·3 (SD 15·6) years to 35·2 (17·0) years across the treatment groups. Both trials met the coprimary endpoints; at week 16, a greater proportion of participants receiving nemolizumab plus TCS-TCI versus placebo plus TCS-TCI had IGA success (ARCADIA 1: 221 [36%] of 620 vs 79 [25%] of 321, adjusted percentage difference 11·5% [97·5% CI 4·7-18·3], p=0·0003; ARCADIA 2: 197 [38%] of 522 vs 69 [26%] of 265, adjusted difference 12·2% [4·6-19·8], p=0·0006) and an EASI-75 response (ARCADIA 1: 270 [44%] vs 93 [29%], adjusted difference 14·9% [7·8-22·0], p<0·0001; ARCADIA 2: 220 [42%] vs 80 [30%], adjusted difference 12·5% [4·6-20·3], p=0·0006). Significant benefits were observed with nemolizumab for all key secondary endpoints including improvement in itch, as early as week 1, and sleep improvement by week 16. The safety profile was similar between nemolizumab plus TCS-TCI and placebo plus TCS-TCI. In the safety sets, 306 (50%) of 616 participants (ARCADIA 1) and 215 (41%) of 519 participants (ARCADIA 2) who received nemolizumab plus TCS-TCI had at least one treatment-emergent adverse event (serious treatment-emergent adverse events in six [1%] and 13 [3%], respectively); and 146 (45%) of 321 (ARCADIA 1) and 117 (44%) of 263 (ARCADIA 2) who received placebo plus TCS-TCI had at least one treatment-emergent adverse event (serious treatment-emergent adverse events in four [1%] and three [1%], respectively). Ten serious treatment-emergent adverse events possibly related to nemolizumab were reported in five (1%) participants in ARCADIA 2. No deaths occurred. Nemolizumab plus TCS-TCI was efficacious and showed statistically and clinically significant improvements in inflammation and itch in adults and adolescents with moderate-to-severe atopic dermatitis. Nemolizumab might offer a valuable extension of current therapies if approved. Galderma.

Left ventricular diastolic dysfunction in patients with heart failure with mildly reduced ejection fraction

ObjectiveThis study investigates the prevalence and prognostic impact of diastolic dysfunction (DD) in patients hospitalized with heart failure (HF) with mildly reduced ejection fraction (HFmrEF) in sinus rhythm. BackgroundData regarding the prognostic impact of DD in patients with HFmrEF is limited. MethodsFrom 2016 to 2022, all patients hospitalized with HFmrEF (i.e., left ventricular ejection fraction 41–49% and signs and/or symptoms of HF) were retrospectively included at one institution. Patients with DD were compared to patients without (i.e., non-DD), further risk stratification was performed according to the severity of DD. The primary endpoint was all-cause mortality at 30 months (interquartile range (IQR) 15–61 months), key secondary endpoint was rehospitalization for worsening HF. ResultsFrom a total of 1154 patients (median age 68 years, 68% males) hospitalized with HFmrEF, concomitant DD was present in 72% (grade I: 56%, grade II: 14%, grade III: 2%). Patients with DD were older (71 years vs. 65 years; p = 0.001) and presented with higher rates of cardiovascular comorbidities. The presence of DD was not associated with the risk of long-term all-cause mortality (adjusted HR = 0.815; 95% CI 0.612–1.085; p = 0.161) or HF-related rehospitalization (adjusted HR = 0.736; 95% CI 0.442–1.225; p = 0.238). Furthermore, the outcome did not differ in patients with more advanced stages of DD. ConclusionDD is commonly prevalent in patients with HFmrEF, but not associated with long-term prognosis.

Efficacy and safety of deuruxolitinib, an oral selective Janus kinase inhibitor, in adults with alopecia areata: Results from the Phase 3 randomized, controlled trial (THRIVE-AA1)

BackgroundAlopecia areata (AA) is a hair loss disorder that can seriously impact quality of life. Janus kinase (JAK) inhibitors, including deuruxolitinib, have previously demonstrated significant hair regrowth in AA. ObjectiveThe Phase 3 THRIVE-AA1 randomized, double-blinded, placebo-controlled trial (NCT04518995) evaluated safety and efficacy of the oral JAK1/JAK2 inhibitor deuruxolitinib in adult patients with AA. MethodsPatients aged 18–65 years with ≥50% hair loss were randomized to deuruxolitinib 8 mg BID, deuruxolitinib 12 mg BID, or placebo for 24 weeks. The primary endpoint was percentage of patients achieving Severity of Alopecia Tool (SALT) score ≤20. A key secondary endpoint was percentage of satisfaction of hair patient-reported outcome (SPRO) responders. ResultsSignificantly higher proportions of patients taking deuruxolitinib met the primary endpoint (8 mg 29.6%; 12 mg 41.5% versus placebo 0.8%). Both deuruxolitinib doses achieved significant improvements in all secondary endpoints versus placebo, including SPRO (8 mg 42.1%; 12 mg 53.0% versus placebo 4.7%). Most treatment-emergent adverse events were mild or moderate, consistent with other oral JAK inhibitors. LimitationsFurther studies are required to understand longer-term safety, efficacy, and impact of treatment cessation. ConclusionBoth doses of deuruxolitinib were effective for hair regrowth. Patient satisfaction aligned with hair growth.

Early Conversion to Everolimus Within 180 Days of Living Donor Liver Transplantation.

Early conversion to Everolimus (EVR) post deceased donor liver transplant has been associated with improved renal function but increased rejection. Early EVR conversion has not been evaluated after living donor liver transplant (LDLT). A retrospective cohort study was conducted to compare the rate of rejection and renal function in patients converted to EVR early post-LDLT to patients on calcineurin inhibitors (CNIs). This was a single center retrospective cohort study of adult LDLT recipients between January 2012 and July 2019. Patients converted to EVR within 180 days of transplant were compared to patients on CNIs. The primary endpoint was biopsy proven acute rejection (BPAR) at 24 months posttransplant. Key secondary endpoints included eGFR at 24 months, change in eGFR, adverse events, and all-cause mortality. From a total of 173 patients involved in the study: 58 were included in the EVR group and 115 in the CNI group. Median conversion to EVR was 26 days post-LDLT. At 24 months, there was no difference in BPAR (22.7% EVR vs. 19.1% CNI, p = 0.63). Median eGFR at 24 months posttransplant was not significantly different (68.6 [24.8 to 112.4] mL/min EVR vs. 75.9 [35.6-116.2] mL/min CNI, p = 0.103). Change in eGFR from baseline was worse in the EVR group (-13.0 [-39.9 to 13.9] mL/min EVR vs. -5.0 [-31.2 to 21.2] mL/min CNI, p = 0.047). Median change from conversion to 24 months posttransplant (EVR group only) was -3.43mL/min/1.73 m2 (-21.0 to 9.6). Early EVR conversion was not associated with increased risk of rejection among LDLT recipients. Renal function was not impacted. EVR may be considered as an alternative after LDLT in patients intolerant of CNIs.

Salvaging the transected hypoglossal nerve using descendens hypoglossi in patients undergoing hypoglossal-facial nerve anastomosis for facial palsy: a randomized clinical trial.

Hypoglossal-facial nerve anastomosis (HFA) is the most commonly used surgical treatment for severe facial palsy that does not respond to conservative treatments. A major complication of HFA is the loss of tongue function. The authors aimed to evaluate whether anastomosing the transected hypoglossal nerve using the ramus descendens hypoglossi could prevent tongue deviation and dysfunction in patients undergoing HFA. In this randomized trial, adult patients with severe peripheral facial palsy (House-Brackmann grade V or VI) who did not respond to at least 6 months of conservative treatment were randomized at a 1:1 ratio to undergo either HFA alone (control group) or HFA plus anastomosis between the hypoglossal nerve and descendens hypoglossi (intervention group). The primary endpoint was tongue deviation angle at 12 months. Key secondary endpoints included tongue disability (chewing difficulty, swallowing defect, and articulation defect), tongue disability index (TDI; range 1-4, with a higher score indicating more severe disability), and facial nerve function. Twenty patients were enrolled (10 in each group). At 12 months, the tongue deviation angle was significantly lower in the intervention group than in the control group (7.8° ± 5.1° vs 23.6° ± 9.6°, p < 0.001). Although not statistically significant, the intervention group had lower rates of chewing difficulty (1/10 vs 3/10, p = 0.58), swallowing defect (1/10 vs 5/10, p = 0.14), and articulation defect (2/10 vs 6/10, p = 0.17). TDI was significantly lower in the intervention group (1.5 ± 0.6 vs 2.5 ± 0.3, p < 0.001). The percentage of the patients achieving House-Brackmann grade II or III was 80% in each group. Anastomosis of the descendens hypoglossi to the transected hypoglossal nerve attenuated tongue deviation in patients undergoing HFA for facial palsy, without compromising facial nerve function.

Empagliflozin to prevent post-operative atrial fibrillation in patients undergoing coronary artery bypass graft surgery: Rationale and design of the EMPOAF trial.

Postoperative atrial fibrillation (POAF) is one of the most common types of acute AF and can complicate the treatment course of approximately one third of patients undergoing cardiac surgery. Sodium-glucose cotransporter-2 (SGLT2) inhibitors are among the newest antidiabetic drugs which can be therapeutic options for preventing POAF by different mechanisms. Empagliflozin to Prevent POAF (EMPOAF) is an interventional, investigator-initiated, double-blind, placebo-controlled, multicenter, randomized controlled trial which will be conducted in two referral teaching cardiology hospitals in Tehran. Four-hundred ninety-two adult patients who are scheduled for elective isolated coronary artery bypass graft (CABG) surgery will be randomly assigned to one of the groups of intervention (empagliflozin 10mg daily) or placebo starting at least 3 days before surgery until discharge. Key exclusion criteria are a history of diabetes mellitus, AF, ketoacidosis, or recurrent urinary tract infections along with severe renal or hepatic impairment, unstable hemodynamics, and patients receiving SGLT2 inhibitors for another indication. The primary outcome will be the incidence of POAF. Key secondary endpoints will be the composite rate of life-threatening arrhythmias, postoperative acute kidney injury, hospitalization length, in-hospital mortality, stroke, and systemic embolization. Key safety endpoints will be the rate of life-threatening and/or genitourinary tract infections, hypoglycemia, and ketoacidosis. EMPOAF will prospectively evaluate whether empagliflozin 10mg daily can reduce the rate of POAF in patients undergoing elective CABG. Enrolment into this study has started by November 2023 and is expected to be ended before the end of 2025.

A Phase I/II Trial of Sapanisertib in Advanced Anaplastic and Radioiodine Refractory Differentiated Thyroid Carcinoma

Abstract Background There are limited therapeutic options for patients with recurrent/metastatic anaplastic thyroid carcinoma (ATC) and radioiodine refractory (RAIR) differentiated thyroid carcinoma (DTC) refractory to multikinase inhibitors. This multicenter trial evaluated sapanisertib, a next-generation oral kinase inhibitor of mTOR complexes 1/2, in ATC and RAIR DTC. Methods A safety run-in phase I was followed by nonrandomized phase II trial in ATC, with an exploratory cohort in RAIR DTC. The primary endpoint was the proportion of patients with ATC who were without disease progression at 4 months. Safety and survival outcomes were key secondary endpoints. Results Forty-six patients (20 ATC, 26 DTC) were enrolled including 40 (18 ATC, 22 DTC) who received recommended phase II dose of 5 mg daily. Eleven percent [2/18, 95% confidence interval (CI): 1.4-34.7%] of patients with ATC were progression-free at 4 months; 22.2% (4/18) had stable disease as best response. Enrollment in the ATC cohort stopped early with 18 patients out of the proposed 23 due to overall futility. One confirmed partial response (4.5%, 1/22) occurred in RAIR DTC, with stable disease in 63.6% (14/22) patients. Median progression-free survival was 1.6 (95% CI: 0.9-2.8) months and 7.8 (2.0–not reached) months in ATC and DTC, respectively. Grade 3 treatment-related adverse events occurred in 30% of patients who received the phase II dose, with the most common being anorexia, nausea, diarrhea, fatigue, skin rash, and hyperglycemia. Genomic alterations in the PI3K/AKT/mTOR pathway were not associated with response or progression-free survival. Conclusion Sapanisertib monotherapy did not meet the primary endpoint of this trial (proportion progression-free at 4 months) in ATC and did not show clinically meaningful activity. Clinical trials with alternative therapeutic strategies are needed.

Neoadjuvant anthracycline followed by toripalimab combined with nab-paclitaxel in patients with early triple-negative breast cancer (NeoTENNIS): a single-arm, phase II study

Toripalimab, a novel PD-1 antibody, is approved for treatment of multiple solid tumors; however, its neoadjuvant use with chemotherapy for triple-negative breast cancer (TNBC) remains unevaluated. Additionally, induction chemotherapy followed by de-escalation of neoadjuvant immunotherapy remains underexplored. Therefore, we conducted a phase II trial investigating a novel neoadjuvant chemoimmunotherapy regimen including de-escalation of immunotherapy for early-stage TNBC. Chemotherapy and anti-PD-1 therapy were sequentially administered in a neoadjuvant setting to female patients with histologically confirmed stage II-III TNBC between June 9, 2020, and March 24, 2022. Patients received neoadjuvant therapy with four cycles of epirubicin-cyclophosphamide every 2 weeks, followed by toripalimab (240mg) every 3 weeks plus nab-paclitaxel weekly for 12 weeks. The primary endpoint was total pathological complete response (tpCR; ypT0/is ypN0). Key secondary endpoints included breast pCR (bpCR; ypT0/is), event-free survival and biomarker analysis. Safety was also assessed. This study was registered with ClinicalTrials.gov (NCT04418154). Among 70 enrolled patients (median age, 51 years; 62.9% stage III), 66 completed treatment without progression and subsequently underwent surgery. The percentages of patients with a tpCR and bpCR were 39 of 70 (55.7%, 95% confidence interval [CI]: 43.3-67.6) and 41 of 70 (58.6%, 95% CI 46.2-70.2), respectively. Sixteen (22.9%) patients experienced grade ≥3 adverse events (AEs), frequently neutropenia (12, 17.1%) and leukopenia (11, 15.7%). The most common immune-related AE was hypothyroidism (5, 7.1%, all grade 1-2). Including 12 weeks of toripalimab in neoadjuvant chemotherapy conferred encouraging activity and manageable toxicity in patients with early TNBC, and this regimen warrants further investigation.

Dupilumab for Eosinophilic Esophagitis in Patients 1 to 11 Years of Age

BackgroundDupilumab is a human monoclonal antibody that blocks interleukin-4 and interleukin-13 pathways and has shown efficacy in five different atopic diseases marked by type 2 inflammation, including eosinophilic esophagitis in adults and adolescents.MethodsIn this phase 3 trial, we randomly assigned, in a 2:2:1:1 ratio, patients 1 to 11 years of age with active eosinophilic esophagitis who had had no response to proton-pump inhibitors to 16 weeks of a higher-exposure or lower-exposure subcutaneous dupilumab regimen or to placebo (two groups) (Part A). At the end of Part A, eligible patients in each dupilumab group continued the same regimen and those in the placebo groups were assigned to higher-exposure or lower-exposure dupilumab for 36 weeks (Part B). At each level of exposure, dupilumab was administered in one of four doses tiered according to baseline body weight. The primary end point was histologic remission (peak esophageal intraepithelial eosinophil count, ≤6 per high-power field) at week 16. Key secondary end points were tested hierarchically.ResultsIn Part A, histologic remission occurred in 25 of the 37 patients (68%) in the higher-exposure group, in 18 of the 31 patients (58%) in the lower-exposure group, and in 1 of the 34 patients (3%) in the placebo group (difference between the higher-exposure regimen and placebo, 65 percentage points [95% confidence interval {CI}, 48 to 81; P<0.001]; difference between the lower-exposure regimen and placebo, 55 percentage points [95% CI, 37 to 73; P<0.001]). The higher-exposure dupilumab regimen led to significant improvements in histologic, endoscopic, and transcriptomic measures as compared with placebo. The improvements in histologic, endoscopic, and transcriptomic measures between baseline and week 52 in all the patients were generally similar to the improvements between baseline and week 16 in the patients who received dupilumab in Part A. In Part A, the incidence of coronavirus disease 2019, nausea, injection-site pain, and headache was at least 10 percentage points higher among the patients who received dupilumab (at either dose) than among those who received placebo. Serious adverse events were reported in 3 patients who received dupilumab during Part A and in 6 patients overall during Part B.ConclusionsDupilumab resulted in histologic remission in a significantly higher percentage of children with eosinophilic esophagitis than placebo. The higher-exposure dupilumab regimen also led to improvements in measures of key secondary end points as compared with placebo.

The efficacy and safety of iGlarLixi versus IDegAsp in Chinese people with type 2 diabetes suboptimally controlled with oral antidiabetic drugs: The Soli-D randomized controlled trial.

To compare the efficacy and safety of a fixed-ratio combination of insulin glargine 100 U/mL plus lixisenatide (iGlarLixi) with premixed insulin, insulin degludec plus insulin aspart (IDegAsp), in Chinese people with type 2 diabetes (T2D) suboptimally controlled with oral antidiabetic drug(s) (OADs). In Soli-D, a 24-week, multicentre, open-label, study, insulin-naïve adults were randomized 1:1 to once-daily injections of iGlarLixi (n = 291) or IDegAsp (n = 291), with continued metformin ± sodium-glucose co-transporter-2 inhibitors. The primary endpoint was non-inferiority in HbA1c change from baseline to week 24. Key secondary endpoints included superiority in HbA1c change and body weight (BW) change at week 24. Hypoglycaemia rates were also assessed. At week 24, iGlarLixi showed non-inferiority and superiority over IDegAsp in HbA1c reduction (least squares [LS] mean difference: -0.20 [95% confidence interval {CI}: -0.33, -0.07]; P < .001 for non-inferiority; [97.5% CI: -0.35, -0.05]; P = .003 for superiority). iGlarLixi decreased BW and IDegAsp increased BW from baseline to week 24, with a statistically significant LS mean difference of -1.49 kg in favour of iGlarLixi (97.5% CI: -2.32, -0.66; P < .001). Event rates (per person-year) for American Diabetes Association (ADA) Level 1, 2 or 3 hypoglycaemia were lower for iGlarLixi (1.90) versus IDegAsp (2.72) (relative risk: 0.71; 95% CI: 0.52, 0.98). No ADA Level 3 hypoglycaemia or unexpected safety findings were reported. In Chinese people with T2D suboptimally controlled with OADs, once-daily iGlarLixi provided better glycaemic control with BW benefit and lower hypoglycaemia event rates versus IDegAsp.

TRLS-12. EFFICACY AND SAFETY OF ENTRECTINIB IN CHILDREN WITHNTRK ORROS1 FUSION-POSITIVE (FP) PRIMARY CENTRAL NERVOUS SYSTEM (CNS) TUMORS

Abstract BACKGROUND Entrectinib (CNS-penetrant, TRK/ROS1 inhibitor) has shown efficacy and safety in children with NTRK/ROS1-fp CNS tumors. We present updated data from an integrated analysis of children with NTRK/ROS1-fp CNS tumors enrolled in three early-phase trials: STARTRK-NG (NCT02650401), TAPISTRY (NCT04589845) and STARTRK-2 (NCT02568267). METHODS TRK/ROS1 inhibitor-naïve patients &amp;lt;18 years old (YO) with NTRK/ROS1-fp CNS tumors with measurable/evaluable-only disease, who received ≥1 entrectinib dose before disease progression, unacceptable toxicity, or consent withdrawal, and with ≥6 months’ follow-up were efficacy evaluable. Any &amp;lt;18 YO on study who received ≥1 entrectinib dose, regardless of genetic alteration and follow-up duration, was evaluable for safety. Primary endpoint: blinded independent central review (BICR)-assessed confirmed objective response rate (ORR). Key secondary endpoints: BICR-assessed confirmed ORR in patients with measurable disease; duration of confirmed response (DoR); time to confirmed response (TtR); progression-free survival (PFS); safety. RESULTS On 16 July 2023 (cut-off for analysis), 27 patients were efficacy evaluable (NTRK-fp: n=20; ROS1-fp: n=7). Median age at enrolment: 4.0 Y (NTRK-fp) and 6.0 Y (ROS1-fp); 45.0% (NTRK-fp) and 42.9% (ROS1-fp) of patients received ≥2 prior therapy lines. Median survival follow-up: 26.2 months (NTRK-fp); 36.1 months (ROS1-fp). ORR: 50.0% (NTRK-fp) and 71.4% (ROS1-fp) in efficacy-evaluable patients, and 58.8% (n=10/17; NTRK-fp) and 83.3% (n=5/6; ROS1-fp) in patients with measurable disease. Median DoR: 25.4 months, TtR: 1.9 months, PFS: 23.1 months in NTRK-fp patients. DoR and PFS were not evaluable in ROS1-fp patients; median TtR was 1.9 months. In the safety-evaluable population (N=34), the most common adverse events were weight increase (50.0%), blood creatinine increase and anemia (each 41.2%). Bone fractures were reported in 26.5% of patients. Most fractures occurred in children 2–12 YO (n=7/9). CONCLUSIONS Our analysis confirms the rapid and durable activity of entrectinib in children with NTRK/ROS1-fp primary CNS tumors. The safety profile described was in line with previous reports.

1856-LB: Efficacy and Safety of Mazdutide in Chinese Participants with Overweight or Obesity (GLORY-1)

Introduction &amp; Objective: To evaluate the efficacy and safety of mazdutide, a once-weekly GLP-1 and glucagon receptor dual agonist, in Chinese participants with overweight or obesity. Methods: In this phase 3 randomized, double-blind, placebo-controlled trial (NCT05607680), we assigned 610 Chinese adults with a BMI of 28 kg/m2 or more, or 24 kg/m2 or more and at least one weight-related comorbidity, in a 1:1:1 ratio to receive once-weekly, subcutaneous mazdutide 4 mg, 6 mg or placebo for 48 weeks. Co-primary endpoints were the percentage change in weight from baseline and a weight reduction of 5% or more at week 32. Results: At baseline, the mean body weight was 87.2 kg, the mean BMI was 31.1 kg/m2, and 83.1% of participants had a BMI of 28 kg/m2 or more. Mazdutide met co-primary endpoints and all key secondary endpoints, demonstrating superiority to placebo on body weight changes, weight-loss targets, and improvements on multiple cardiometabolic risk factors (Table). Mazdutide was well tolerated, with adverse events leading to treatment discontinuation reported in 1.5% of participants with mazdutide 4 mg, 0.5% with mazdutide 6 mg and 1.0% with placebo. The most frequently reported adverse events were gastrointestinal, mostly mild to moderate in severity. Conclusion: In Chinese adults with overweight or obesity, mazdutide provides significant reductions in body weight and cardiometabolic risk factors. Disclosure L. Ji: None. H. Jiang: None. H.

Association between prenatal glucocorticoid exposure and adolescent neurodevelopment: An observational follow-up study.

Prenatal exposure to supraphysiological glucocorticoid (GC) levels may lead to long-lasting developmental changes in numerous biological systems. Our prior study identified an association between prenatal GC prophylaxis and reduced cognitive performance, electrocortical changes, and altered autonomic nervous system (ANS) activity in children aged 8-9 years. This follow-up study aimed to examine whether these findings persisted into adolescence. Prospective observational follow-up study involving twenty-one 14- to 15-year-old adolescents born to mothers who received betamethasone for induction of fetal lung maturation in threatened preterm birth, but who were born with a normal weight appropriate for their gestational age (median 37+4 gestational weeks). Thirty-five children not exposed to betamethasone served as the reference group (median 37+6 gestational weeks). The primary endpoint was cognitive performance, measured by intelligence quotient (IQ). Key secondary endpoints included symptoms of attention-deficit/hyperactivity disorder (ADHD) and metabolic markers. Additionally, we determined electrocortical (electroencephalogram), hypothalamus-pituitary-adrenal axis (HPAA), and ANS activity in response to a standardized stress paradigm. No statistically significant group difference was observed in global IQ (adjusted mean: betamethasone 103.9 vs references 105.9, mean difference -2.0, 95% confidence interval [CI]: -7.12 to 3.12, p = 0.44). Similarly, ADHD symptoms, metabolic markers, the overall and stress-induced activity of the HPAA and the ANS did not differ significantly between groups. However, the betamethasone group exhibited reduced electrocortical activity in the frontal brain region (spectral edge frequency-adjusted means: 16.0 Hz vs 17.8 Hz, mean difference -1.83 Hz, 95% CI: -3.21 to -0.45, p = 0.01). In 14- to 15-year-old adolescents, prenatal GC exposure was not associated with differences in IQ scores or ANS activity compared to unexposed controls. However, decelerated electrocortical activity in the frontal region potentially reflects disturbances in the maturation of cortical and/or subcortical brain structures. The clinical significance of these changes remains unknown. Given the small sample size, selective participation/loss of follow-up and potential residual confounding, these findings should be interpreted cautiously. Further research is required to replicate these results in larger cohorts before drawing firm clinical conclusions.

One-Month Versus Three-Month Dual-Antiplatelet Therapy in High Bleeding Risk Patients With Chronic Kidney Disease

Shortening the duration of dual-antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI) was shown to be effective and safe in patients at high bleeding risk (HBR). We aimed to investigate the effect of 1 versus 3-month DAPT on outcomes after drug-eluting stent in HBR patients with or without chronic kidney disease (CKD). Data from 3 prospective single-arm studies (XIENCE Short DAPT Program) enrolling HBR patients after successful coronary implantation of cobalt-chromium everolimus-eluting stent (XIENCE, Abbott) were analyzed. Subjects were eligible for DAPT discontinuation at 1 or 3 months if free from ischemic events. The primary end point was all-cause death or any myocardial infarction. The key secondary end point was Bleeding Academic Research Consortium Type 2 to 5 bleeding. Outcomes were assessed from 1 to 12 months after PCI. CKD was defined as baseline creatinine clearance <60 ml/min. Of 3,286 patients, 1,432 (43.6%) had CKD. One-month versus 3-month DAPT was associated with a similar 12-month risk of the primary outcome irrespective of CKD status (CKD: 9.5% vs 10.9%, adjusted hazard ratio 0.86, 95% confidence interval 0.60 to 1.22; no-CKD: 6.6% vs 5.6%, adjusted hazard ratio 1.15, 95% confidence interval 0.77 to 1.73; p interaction 0.299). Bleeding Academic Research Consortium 2 to 5 bleeding rates were numerically but not significantly lower with 1-month versus 3-month DAPT in both CKD (9.9% vs 12%) and no-CKD (6.4% vs 9.0%) patients. In conclusion, in HBR patients, 1-month versus 3-month DAPT was associated with a similar risk of ischemic complications and a trend toward fewer bleeding events at 12 months after PCI, irrespective of CKD status.
