Abstract
BACKGROUND Curcumin-piperine might synergise with vitamin D to induce clinical remission in patients with systemic lupus erythematosus (SLE). OBJECTIVE To observe the improvement of patients with SLE clinically and the levels of inflammatory cytokines after receiving supplements of curcumin-piperine and cholecalciferol (Vitamin D3). METHODS Forty-five female SLE patients were included in a three-month double-blind, randomized controlled trial. Participants were classified into: Group I (400 IU cholecalciferol + placebo three times daily, n = 15), Group II (600 mg curcumin + 15,800 m piperine once daily and three times daily placebo, n = 15), and Group III (cholecalciferol 400 IU three times and 600 mg curcumin + 15,800 mg piperine once a day, n = 15). Mexican SLE disease activity score (Mex- SLEDAI), fatigue severity scale (FSS), TGF-β, and IL-6 levels were measured from all patients before and after the treatments. RESULTS Mex-SLEDAI, FSS, and IL-6 were reduced significantly, while TGF-β serum levels were increased in all groups after the treatments (p <0.05). Changes in Mex-SLEDAI score (p = 0.003 and p = 0.008), FSS (p = 0.001 and p <0.001), and TGF-β (p = 0.003 and p = 0.004) serum levels were significantly higher in group III compared to the group I or group II. On the other hand, changes in Mex-SLEDAI, FSS, IL-6, and TGF-β serum levels were similar between groups I and II. CONCLUSION Although vitamin D or curcumin-piperine alone could improve the clinical outcome and cytokines levels in SLE, curcumin-piperine combined with vitamin D had the best outcome in improving the disease activity and cytokines levels among patients with SLE.

Abstract
BACKGROUND Mitochondrial dysfunction and impaired mitophagy are integral to myocyte loss and the progression of heart failure. Urolithin A (UA), a microbiota-produced metabolite of ellagitannins and ellagic acid, is a known stimulator of mitophagy and mitochondrial biogenesis that has shown cardioprotective effects in experimental models. METHODS A randomized, double-blind, placebo-controlled 2×2 crossover trial was conducted on 10 patients with HF with reduced ejection fraction (HFrEF). The trial design involved two 4- week intervention periods of UA (500 mg BID) and placebo, separated by a 2-week washout phase. The patients underwent two-dimensional echocardiogram examination as well as blood sampling at the beginning and end of each period. RESULTS All patients completed the study. The results failed to reveal any significant effect of UA supplementation on echocardiographic measures (LVEF, LVEDD, LVESV, and TAPSE). Plasma concentrations of pro-BNP, glucose, and CRP (p >0.05) were also not altered. Serum HDL-C levels were increased with UA compared with placebo (+6.46±2.33 mg/dL, p =0.026), whereas other lipid indices (LDL-C, triglycerides, total cholesterol, and VLDL-C) remained unchanged (p >0.05). CONCLUSION The results of the present study do not support any positive effect of UA supplementation in improving echocardiographic and biochemical indices of HFrEF. Further studies with higher doses of UA and longer supplementation duration are encouraged to be conducted. CLINICAL TRIAL REGISTRATION NUMBER IRCT20210216050375N1.

Abstract
BACKGROUND Patients with relapsed or refractory acute myeloid leukemia (R/R AML) and FLT3-internal tandem duplication (FLT3-ITD) respond infrequently to salvage chemotherapy. OBJECTIVE To investigate the efficacy of sorafenib plus triplet therapy with venetoclax, azacitidine, and homoharringtonine (VAH) as a salvage therapy in this population. METHODS This multicenter, single-arm, phase 2 study was conducted at 12 hospitals across China. Eligible patients had R/R AML with FLT3-ITD (aged 18-65 years) who were treated with VAH. The primary endpoint was composite complete remission (CRc) after two cycles. Secondary outcomes included the overall response rate (ORR), safety, and survival. RESULTS Between July 9, 2020, and March 19, 2022, 58 patients were assessed for eligibility, 51 of whom were enrolled. The median patient age was 47 years (interquartile range [IQR] 31-57). CRc was 76.5% with ORR of 82.4%. At a median follow-up of 17.7 months (IQR, 8.7-24.7), the median duration of CRc was not reached (NR), overall survival was 18.1 months (95% confidence interval [CI], 11.8-NR) and event-free survival was 11.4 months (95% CI, 5.6-NR). Grade 3 or 4 adverse events occurring in ≥10% of patients included neutropenia in 47 (92.2%), thrombocytopenia in 41 (80.4%), anemia in 35 (68.6%), febrile neutropenia in 29 (56.9%), pneumonia in 13 (25.5%), and sepsis in 6 (11.8%) patients. Treatment-related death occurred in two (3.9%) patients. CONCLUSIONS The sorafenib plus VAH regimen was well tolerated and highly active against R/R AML with FLT3-ITD. This regimen may be a suitable therapeutic option for this population, but larger population trials are needed to be explored. TRIAL REGISTRATION Clinical Trials Registry: NCT04424147.

Abstract
BACKGROUND About half of the world's population lives in dengue-endemic areas. We aimed to evaluate the long-term efficacy and safety of two doses of the tetravalent dengue vaccine TAK-003 in preventing symptomatic dengue disease of any severity and due to any dengue virus (DENV) serotypes in children and adolescents. METHODS In this ongoing double-blind, randomised, placebo-controlled trial, we enrolled healthy participants aged 4-16 years at 26 medical and research centres across eight dengue-endemic countries (Brazil, Colombia, Dominican Republic, Nicaragua, Panama, Philippines, Sri Lanka, and Thailand). The main exclusion criteria were febrile illness (body temperature ≥38°C) at the time of randomisation, hypersensitivity or allergy to any of the vaccine components, pregnancy or breastfeeding, serious chronic or progressive disease, impaired or altered immune function, and previous receipt of a dengue vaccine. Participants were randomly assigned 2:1 (stratified by age and region) using an interactive web response system and dynamic block assignment to receive two subcutaneous doses of TAK-003 or placebo 3 months apart. Investigators, participants, and their parents or legal guardians were blinded to group assignments. Active febrile illness surveillance and RT-PCR testing of febrile illness episodes were performed for identification of virologically confirmed dengue. Efficacy outcomes were assessed in the safety analysis set (all randomly assigned participants who received ≥1 dose) and the per protocol set (all participants who had no major protocol violations), and included cumulative vaccine efficacy from first vaccination to approximately 4·5 years after the second vaccination. Serious adverse events were monitored throughout. This study is registered with ClinicalTrials.gov, NCT02747927. FINDINGS Between Sept 7, 2016, and March 31, 2017, 20 099 participants were randomly assigned (TAK-003, n=13 401; placebo, n=6698). 20 071 participants (10 142 [50·5%] males; 9929 [49·5%] females; safety set) received TAK-003 or placebo, with 18 257 (91·0%) completing approximately 4·5 years of follow-up after the second vaccination (TAK-003, 12 177/13 380; placebo, 6080/6687). Overall, 1007 (placebo: 560; TAK-003: 447) of 27 684 febrile illnesses reported were virologically confirmed dengue, with 188 cases (placebo: 142; TAK-003: 46) requiring hospitalisation. Cumulative vaccine efficacy was 61·2% (95% CI 56·0-65·8) against virologically confirmed dengue and 84·1% (77·8-88·6) against hospitalised virologically confirmed dengue; corresponding efficacies were 53·5% (41·6-62·9) and 79·3% (63·5-88·2) in baseline seronegative participants (safety set). In an exploratory analysis, vaccine efficacy was shown against all four serotypes in baseline seropositive participants. In baseline seronegative participants, vaccine efficacy was shown against DENV-1 and DENV-2 but was not observed against DENV-3 and low incidence precluded evaluation against DENV-4. During part 3 of the trial (approximately 22-57 months after the first vaccination), serious adverse events were reported for 664 (5·0%) of 13 380 TAK-003 recipients and 396 (5·9%) of 6687 placebo recipients; 17 deaths (6 in the placebo group and 11 in the TAK-003 group) were reported, none were considered study-vaccine related. INTERPRETATION TAK-003 demonstrated long-term efficacy and safety against all four DENV serotypes in previously exposed individuals and against DENV-1 and DENV-2 in dengue-naive individuals.

Abstract
BACKGROUND A once-daily, three-pronged approach using an antibiotic, antibacterial, and retinoid may provide faster acne improvement versus monotherapy or dual-combination products. This post hoc analysis compared threshold acne lesion reductions with clindamycin phosphate 1.2%/adapalene 0.15%/benzoyl peroxide 3.1% (CAB) gel—the first FDA-approved triple-combination topical acne product—to its dyads and vehicle. METHODS Phase 2 (N=741; NCT03170388) and phase 3 (N=183; N=180; NCT04214639; NCT04214652), double-blind, 12-week studies randomized participants aged ≥9 years with moderate-to-severe acne to once-daily CAB or vehicle gel; the phase 2 study included three additional dyad gel arms. The pooled percentage of participants achieving ≥33%, ≥50%, and ≥75% reduction in inflammatory and noninflammatory acne lesions was evaluated. RESULTS As early as week 4 in the phase 2 study, ≥33% reduction in inflammatory lesions occurred in a significantly greater percentage of CAB gel-treated participants (82.7%) than with the 3 dyads and vehicle (61.1-69.8%; P<0.05, all). These early reductions were sustained throughout the study, with significantly (P<0.05) more CAB-treated participants achieving ≥50% reduction in inflammatory lesions versus dyads and vehicle from weeks 4-12. By week 12, CAB led to substantial reductions of ≥75% in significantly more participants than dyads and vehicle (65.8% vs 49.9-51.2% and 21.6%; P<0.05, all). Similar trends were observed for noninflammatory lesions in the phase 2 study and for inflammatory and noninflammatory lesions in the phase 3 studies. CONCLUSIONS Lesion count reductions were significantly greater with CAB versus its dyads and vehicle gel as early as week 4, with substantial reductions observed after 12 weeks of treatment. This faster-acting and sustained efficacy of CAB gel—coupled with its optimized formulation, once-daily dosing, and tolerability—may positively impact treatment adherence.

Abstract
BACKGROUND In 2005, the Institute of Medicine advised using methods other than nitrogen balance (NB) for determining protein requirements. Since then, protein requirements using indicator amino acid oxidation (IAAO) have been published and are higher than NB. Glutathione (GSH), a tripeptide of cysteine, glutamate, and glycine, is a principal antioxidant that can be used as a functional indicator of protein adequacy. OBJECTIVES The aim of this study was to measure changes in erythrocyte GSH kinetics [fractional synthesis rate (FSR) and absolute synthesis rate (ASR)] in healthy adults following a range of protein intakes at and above the current recommendations. METHODS Sixteen healthy adults [8 males and 8 females, aged 25.6 ± 0.9 y (mean ± SEM)] were studied at 4 of 6 protein intakes ranging from 0.6 to 1.5 g⋅kg-1⋅d-1. Erythrocyte GSH kinetics were assessed during a 7-h infusion of [U-13C2-15N]glycine following 2 d of adaptation to each protein intake. Blood and urine tests were performed to measure oxidative stress markers, plasma homocysteine, triglycerides, plasma amino acid concentrations, 5-L-oxoproline (5-OP), and urinary sulfate. The protein intake that maximized GSH synthesis was determined using mixed-effect change-point regression in R. Primary and secondary outcomes were analyzed using linear mixed-effects and repeated-measures analysis of variance with Tukey's post hoc test. RESULTS The protein intake that maximized GSH FSR at 78%⋅d-1 was 1.0 g⋅kg-1⋅d-1 (95% confidence interval: 0.63, 1.39). GSH ASR was significantly lower at 0.6 and 0.8 g⋅kg-1⋅d-1 than at 1.5 g⋅kg-1⋅d-1 (2.03 and 2.17, respectively, compared with 3.71 mmol⋅L-1⋅d-1). Increasing the protein intake led to increased urinary sulfate but did not affect erythrocyte GSH concentration, plasma oxidative stress markers, triglycerides, homocysteine, or 5-OP. CONCLUSIONS A protein intake of 1.0 g⋅kg-1⋅d-1 maximized GSH synthesis, which is in agreement with earlier IAAO-derived protein requirements of 0.93 to 1.2 g⋅kg-1⋅d-1. These findings suggest that recommendations based on NB (0.66 g⋅kg-1⋅d-1) may underestimate protein needs for adequate health. This trial was registered at clinicaltrials.gov as NCT02971046.

Abstract
INTRODUCTION The release of tumor-associated antigens with cytotoxic chemotherapy treatment may enhance the response to immune checkpoint blockade. Eribulin is a microtubule inhibitor with proven overall survival (OS) benefit in metastatic breast cancer (MBC), which may also enhance intratumoral vascular remodeling. Durvalumab, a humanized monoclonal antibody, targets the programmed cell death ligand-1 (PD-L1) receptor. This study sought to determine the maximum tolerated dose and recommended phase II dose (RP2D) of eribulin in combination with durvalumab, as well as the safety and preliminary antitumor activity of the combination in patients with previously treated HER2-negative (HER2-) MBC and recurrent ovarian cancer (ROC). METHODS Cohorts of 3-6 patients with HER2- MBC and ROC were treated in a modified 3+3 design. Eligible patients received escalating doses of eribulin (1.1 mg/m2 or 1.4 mg/m2 IV on day 1 and day 8) with durvalumab (1.12 g IV on day 1) in 21-day cycles until dose-limiting toxicity (DLT), intolerable adverse events (AEs), disease progression, or other reasons for withdrawal. PRIMARY ENDPOINT the rate of DLTs during cycles 1 and 2 of therapy. Secondary endpoints: AE rate, objective response rate (ORR), progression-free survival (PFS), and OS. RESULTS Nine patients with a median of 4 prior therapies for advanced disease were treated: 5 patients with HER2- MBC (1 with triple-negative disease and 4 with hormone-positive disease) and 4 patients with ROC. The RP2D of eribulin was 1.4 mg/m2 in combination with durvalumab. There were no DLTs experienced during the first two cycles of therapy. The most common treatment-related AEs (>50%) were fatigue, neutropenia, decreased white blood cell count, anemia, AST and alkaline phosphatase elevation, hyperglycemia, and nausea; most were grade 1 or 2. There was one immune-related AE of grade 3 (hepatitis) after 5 cycles of treatment, for which patient came off study. Two other patients discontinued study drug related to toxicity (neutropenia [n = 1], hepatic toxicity [n = 1]). ORR was 55%, and 4 additional patients experienced stable disease. All MBC patients exhibited a response to therapy. Median PFS was 6.2 months. Median OS was 15.0 months. CONCLUSION The combination of eribulin at a dose of 1.4 mg/m2 with standard dose durvalumab had a favorable AE profile in patients with previously treated HER2- MBC and ROC. The early antitumor activity observed in all MBC patients enrolled in the study suggests that further investigation of this combination is warranted.

Abstract
Natural killer T cell lymphoma (NKTCL) is highly aggressive, with advanced stage patients poorly responding to intensive chemotherapy. To explore effective and safe treatment for newly diagnosed advanced stage NKTCL, we conducted a phase II study of anti-metabolic agent pegaspargase plus PD-1 antibody sintilimab (NCT04096690). Twenty-two patients with a median age of 51 years (range, 24-74) were enrolled and treated with induction treatment of pegaspargase 2500 IU/m2 intramuscularly on day 1 and sintilimab 200 mg intravenously on day 2 for 6 cycles of 21 days, followed by maintenance treatment of sintilimab 200 mg for 28 cycles of 21 days. The complete response and overall response rate after induction treatment were 59% (95%CI, 43-79%) and 68% (95%CI, 47-84%), respectively. With a median follow-up of 30 months, the 2 year progression-free and overall survival rates were 68% (95%CI, 45-83%) and 86% (95%CI, 63-95%), respectively. The most frequently grade 3/4 adverse events were neutropenia (32%, n = 7) and hypofibrinogenemia (18%, n = 4), which were manageable and led to no discontinuation of treatment. Tumor proportion score of PD-L1, peripheral blood high-density lipoprotein cholesterol, and apolipoprotein A-I correlated with good response, while PD-1 on tumor infiltrating lymphocytes and peripheral Treg cells with poor response to pegaspargase plus sintilimab treatment. In conclusion, the chemo-free regimen pegaspargase plus sintilimab was effective and safe in newly diagnosed, advanced stage NKTCL. Dysregulated lipid profile and immunosuppressive signature contributed to treatment resistance, providing an alternative therapeutic approach dual targeting fatty acid metabolism and CTLA-4 in NKTCL.
