Abstract
BACKGROUND Chronic rhinosinusitis (CRS) is common in individuals with cystic fibrosis (CF) and is marked by chronic inflammation and episodes of infection that negatively impact quality of life. Several studies have shown that elexacaftor-tezacaftor-ivacaftor (ETI) improves symptoms and examination findings in CF-CRS. The current study determines the effect of ETI on the sinonasal microbiota in CF. METHODS Sinonasal samples were collected under endoscopic visualization before and after starting ETI. Samples were subjected to 16S amplicon sequencing and sequences were processed with the QIIME2 pipeline with subsequent analysis using the vegan R-package. RESULTS Twenty-nine individual baseline samples and 23 sample pairs pre-/post-ETI were available. At baseline, the cohort had samples dominated by Staphylococcus, and alpha diversity was lower than that of a published reference set of individuals without sinonasal disease. Individuals with prior sinus surgery had lower alpha diversity as measured by Shannon Index, Observed Richness, and Faith's phylogenetic diversity Index. Beta diversity differed between individuals with and without allergic rhinitis, with higher Staphylococcus abundance in those with allergic rhinitis. No change in alpha or beta diversity was seen after a median of 9 months on ETI. With ETI, the Pseudomonas genus and the genus containing Burkholderia decreased in samples containing these taxa at baseline. Pseudomonas abundance decreased with treatment as measured by qPCR. Core sinonasal microbiome members Staphylococcus, Corynebacterium, and Streptococcus were unchanged, while Moraxella increased with ETI. CONCLUSIONS Treatment with ETI leads to a reduction in Pseudomonas abundance within the sinonasal microbiome of individuals with Pseudomonas at baseline.

Abstract
BACKGROUND Elexacaftor in combination with Tezacaftor and Ivacaftor (ETI) became licensed in the United Kingdom in early 2022 for children aged 6-11 years with cystic fibrosis (CF) and an eligible mutation. Many in this age group have excellent prior lung health making quantitative measurement of benefit challenging. Clinical trials purport that lung clearance index (LCI2.5) measurement is most suitable for this purpose. OBJECTIVES This study aimed to understand the clinical utility of LCI2.5 in detecting change after commencing ETI in the real world. PATIENT SELECTION/METHODS Baseline anthropometric data were collected along with spirometry (forced expiratory volume in 1 s [FEV1], forced vital capacityFV and LCI2.5 measures in children aged 6-11 years with CF before starting ETI. Measures were repeated after a mean (range) of 8.2 (7-14) months of ETI treatment. The primary endpoint was a change in LCI2.5, with secondary endpoints including change in FEV1 and change in body mass index (BMI) also reported. RESULTS Twelve children were studied (seven male, mean age 9.5 years at baseline). Our study population had a mean (SD) LCI2.5 of 7.01 (1.14) and FEV1 of 96 (13) %predicted at baseline. Mean (95% confidence interval) changes in LCI2.5 [-0.7 (-1.4, 0), p = .06] and BMI [+0.7 (+0.1, +1.3), p = .03] were observed, along with changes in FEV1 of +3.1 (-1.9, +8.1) %predicted. CONCLUSIONS Real-world changes in LCI2.5 (-0.7) are different to those reported in clinical trials (-2.29). Lower baseline LCI2.5 as a result of prior modulator exposure, high baseline lung health, and new LCI2.5 software analyses all contribute to lower LCI2.5 values being recorded in the real world of children with CF.

Abstract
BACKGROUND Janus kinase [JAK] inhibitors [JAKinibs] are effective small molecule therapies for treating Crohn's disease [CD] and ulcerative colitis [UC], collectively known as inflammatory bowel disease [IBD]. By preventing JAKs from phosphorylating signal transducer and activator of transcription proteins, JAKinibs disrupt cytokine signalling pathways that promote inflammation. Despite considerable overlap in the JAKs they target, first- and second-generation JAKinibs display different clinical efficacies in CD and UC. METHODS We conducted a comparative phosflow study of four JAKinibs [filgotinib, upadacitinib, tofacitinib, and deucravacitinib] to observe subtle mechanistic differences that may dictate their clinical behaviour. Resected mesenteric lymph node [MLN] cells from 19 patients [9 CD, 10 UC] were analysed by flow cytometry in the presence or absence of different cytokine stimuli and titrated JAKinibs. RESULTS We found a higher potency of the JAK 1/3-preferential inhibitor, tofacitinib, for JAK 3-dependent cytokine signalling pathways in comparison to filgotinib, but a higher potency of the JAK 1-preferential inhibitors, filgotinib and upadacitinib, for JAK 3-independent cytokine signalling pathways. Deucravacitinib, a TYK2-preferential inhibitor, demonstrated a much narrower selectivity by inhibiting only IL-10 and IFN-β pathways, albeit more potently than the other JAKinibs. Additionally, we found some differences in the sensitivity of immune cells from CD versus UC, and patients with versus without a CD-associated NOD2 polymorphism, to phosphorylate signal transducer and activator of transcriptions in response to specific cytokine stimulation. CONCLUSIONS Despite their similarities, differences exist in the relative potencies of different JAKinibs against distinct cytokine families, to explain their clinical efficacy.

Abstract
BACKGROUND Erosive esophagitis (EE) is a gastroesophageal reflux disease characterized by mucosal breaks in the esophagus. Proton pump inhibitors are widely used as maintenance therapy for EE, but many patients still relapse. In this trial, we evaluated the noninferiority of vonoprazan vs. lansoprazole as maintenance therapy in patients with healed EE. METHODS We performed a double-blind, double-dummy, multicenter, phase 3 clinical trial among non-Japanese Asian adults with endoscopically confirmed healed EE from April 2015 to February 2019. Patients from China, South Korea, and Malaysia were randomized to vonoprazan 10 mg or 20 mg once daily or lansoprazole 15 mg once daily for 24 weeks. The primary endpoint was endoscopically confirmed EE recurrence rate over 24 weeks with a noninferiority margin of 10% using a two-sided 95% confidence interval (CI). Treatment-emergent adverse events (TEAEs) were recorded. RESULTS Among 703 patients, EE recurrence was observed in 24/181 (13.3%) and 21/171 (12.3%) patients receiving vonoprazan 10 mg or 20 mg, respectively, and 47/184 (25.5%) patients receiving lansoprazole (differences: -12.3% [95% CI, -20.3% to -4.3%] and -13.3% [95% CI, -21.3% to -5.3%], respectively), meeting the primary endpoint of noninferiority to lansoprazole in preventing EE recurrence at 24 weeks. Evidence of superiority (upper bound of 95% CI <0%) was also observed. At 12 weeks, endoscopically confirmed EE recurrence was observed in 5/18, 2/20, and 7/20 of patients receiving vonoprazan 10 mg, vonoprazan 20 mg, and lansoprazole, respectively. TEAEs were experienced by 66.8% (157/235), 69.0% (156/226), and 65.3% (158/242) of patients receiving vonoprazan 10 mg, vonoprazan 20 mg, and lansoprazole, respectively. The most common TEAE was upper respiratory tract infection in 12.8% (30/235) and 12.8% (29/226) patients in vonoprazan 10 mg and 20 mg groups, respectively and 8.7% (21/242) patients in lansoprazole group. CONCLUSION Vonoprazan maintenance therapy was well-tolerated and noninferior to lansoprazole for preventing EE recurrence in Asian patients with healed EE.

Abstract
Objective The use of a proton pump inhibitor (PPI) reduces rebleeding and mortality in patients with upper gastrointestinal bleeding (UGIB). Vonoprazan is a novel oral agent with strong and sustained acid-inhibitory activity. We clarified the effect of vonoprazan compared with oral PPIs in such patients. Methods We analyzed the Diagnosis Procedure Combination database. The primary outcome was rebleeding, and secondary outcomes were in-hospital mortality and in-hospital mortality after rebleeding. Propensity score matching was performed to balance the comparison groups, and logistic regression analyses were used to compare the outcomes between vonoprazan and oral PPIs. Patients Patients on vonoprazan or oral PPIs who underwent endoscopic hemostasis for UGIB between 2014 and 2019 were included. Results We enrolled 78,964 patients, of whom 27,101 and 51,863 were prescribed vonoprazan and a PPI, respectively. After propensity score matching, the rebleeding rate of vonoprazan did not significantly differ from that of oral PPIs [6.4% vs. 6.1%; odds ratio (OR), 1.05; 95% confidence interval (CI), 0.98-1.13]; similarly, the in-hospital mortality rate (1.4% vs. 1.5%; OR, 0.91; 95% CI, 0.79-1.05) and in-hospital mortality after rebleeding (0.3% vs. 0.2%; OR, 1.09; 95% CI, 0.78-1.54) also did not significantly differ between the groups. The acquired findings were robust across dose-restricted analyses and several sensitivity analyses. Conclusion Rebleeding and in-hospital mortality risks in patients on vonoprazan were similar to those in patients on oral PPIs. Considering the higher cost of vonoprazan, oral PPIs might be an optimal oral agent as an acid-suppressive therapy in such patients.

Abstract
BACKGROUND Helicobacter pylori (H. pylori) infects over half the global population, causing gastrointestinal diseases like dyspepsia, gastritis, duodenitis, peptic ulcers, G-MALT lymphoma, and gastric adenocarcinoma. Eradicating H. pylori is crucial for treating and preventing these conditions. While conventional proton pump inhibitor (PPI)-based triple therapy is effective, there's growing interest in longer acid suppression therapies. Potassium competitive acid blocker (P-CAB) triple and dual therapy are new regimens for H. pylori eradication. Initially used in Asian populations, vonoprazan (VPZ) has been recently Food and Drug Administration-approved for H. pylori eradication. AIM To assess the efficacy of regimens containing P-CABs in eradicating H. pylori infection. METHODS This study, following PRISMA 2020 guidelines, conducted a systematic review and meta-analysis by searching MEDLINE and Scopus libraries for randomized clinical trials (RCTs) or observational studies with the following command: [("Helicobacter pylori" OR "H pylori") AND ("Treatment" OR "Therapy" OR "Eradication") AND ("Vonaprazan" OR "Potassium-Competitive Acid Blocker" OR "P-CAB" OR "PCAB" OR "Revaprazan" OR "Linaprazan" OR "Soraprazan" OR "Tegoprazan")]. Studies comparing the efficacy of P-CABs-based treatment to classical PPIs in eradicating H. pylori were included. Exclusion criteria included case reports, case series, unpublished trials, or conference abstracts. Data variables encompassed age, diagnosis method, sample sizes, study duration, intervention and control, and H. pylori eradication method were gathered by two independent reviewers. Meta-analysis was performed in R software, and forest plots were generated. RESULTS A total of 256 references were initially retrieved through the search command. Ultimately, fifteen studies (7 RCTs, 7 retrospective observational studies, and 1 comparative unique study) were included, comparing P-CAB triple therapy to PPI triple therapy. The intention-to-treat analysis involved 8049 patients, with 4471 in the P-CAB intervention group and 3578 in the PPI control group across these studies. The analysis revealed a significant difference in H. pylori eradication between VPZ triple therapy and PPI triple therapy in both RCTs and observational studies [risk ratio (RR) = 1.17, 95% confidence interval (CI): 1.11-1.22, P < 0.0001] and (RR = 1.13, 95%CI: 1.09-1.17, P < 0.0001], respectively. However, no significant difference was found between tegoprazan (TPZ) triple therapy and PPI triple therapy in both RCTs and observational studies (RR = 1.04, 95%CI: 0.93-1.16, P = 0.5) and (RR = 1.03, 95%CI: 0.97-1.10, P = 0.3), respectively. CONCLUSION VPZ-based triple therapy outperformed conventional PPI-based triple therapy in eradicating H. pylori, positioning it as a highly effective first-line regimen. Additionally, TPZ-based triple therapy was non-inferior to classical PPI triple therapy.

Abstract
Pancreatic cancer is highly lethal. New diagnostic and treatment modalities are desperately needed. We report here that an expanded porphyrin, cyclo[8]pyrrole (CP), with a high extinction coefficient (89.16 L/g·cm) within the second near-infrared window (NIR-II), may be formulated with an αvβ3-specific targeting peptide, cyclic-Arg-Gly-Asp (cRGD), to form cRGD-CP nanoparticles (cRGD-CPNPs) with promising NIR-II photothermal (PT) therapeutic and photoacoustic (PA) imaging properties. Studies with a ring-array PA tomography system, coupled with analysis of control nanoparticles lacking a targeting element (CPNPs), revealed that cRGD conjugation promoted the delivery of the NPs through abnormal vessels around the tumor to the solid tumor core. This proved true in both subcutaneous and orthotopic pancreatic tumor mice models, as confirmed by immunofluorescent studies. In combination with NIR-II laser photoirradiation, the cRGD-CPNPs provided near-baseline tumor growth inhibition through PTT both in vitro and in vivo. Notably, the combination of the present cRGD-CPNPs and photoirradiation was found to inhibit intra-abdominal metastases in an orthotopic pancreatic tumor mouse model. The cRGD-CPNPs also displayed good biosafety profiles, as inferred from PA tomography, blood analyses, and H&E staining. They thus appear promising for use in combined PA imaging and PT therapeutic treatment of pancreatic cancer.

Abstract
PURPOSE The efficacy of the selective KIT/PDGFRA inhibitor avapritinib (300 mg once daily) was explored in patients with non-PDGFRA-mutant gastrointestinal stromal tumors (GISTs) from the phase I NAVIGATOR and phase I/II CS3007-001 trials. PATIENTS AND METHODS Adults with unresectable/metastatic, KIT-only-mutant GISTs and progression following ≥1 tyrosine kinase inhibitors (TKIs) were included in this post hoc analysis. Baseline mutational status was identified in tumor and plasma. Primary endpoints were objective response rate (ORR) and progression-free survival (PFS) by blinded independent radiology review per modified RECIST v1.1 in patients harboring KIT activation-loop mutations (KIT exons 17 or 18) without ATP binding-pocket mutations (KIT exons 13 or 14; ALposABPneg), and other KIT mutations (OTHERS). RESULTS Sixty KIT ALposABPneg and 100 KIT OTHERS predominantly heavily pretreated patients (61.3% with ≥3 prior TKIs) were included. ORR was significantly higher in KIT ALposABPneg than KIT OTHERS patients (unadjusted: 26.7% vs. 12.0%; P = 0.0852; adjusted: 31.4% vs. 12.1%; P = 0.0047). Median PFS (mPFS) was significantly longer in KIT ALposABPneg patients compared with KIT OTHERS patients (unadjusted: 9.1 vs. 3.5 months; P = 0.0002; adjusted: 9.1 vs. 3.4 months; P < 0.0001), and longer in second- versus later-line settings (19.3 vs. 5.6-10.6 months). Benefit with avapritinib was observed in patients with KIT exon 9 mutations in the ≥4 line settings (mPFS: 5.6 and 3.7 months for 4 line and >4 line, respectively). CONCLUSIONS Avapritinib showed greater antitumor activity in patients with GISTs harboring KIT ALposABPneg mutations versus KIT OTHERS, and may be considered in the former subpopulation. Patients with KIT exon 9 mutations may also benefit in ≥4 line settings.

Abstract
Brain injury in preterm infants is a major cause of disability and mortality in children. GSK-3β is a common pathogenic factor for cognitive dysfunction and involves in neuronal proliferation and differentiation. However, GSK-3β affected neuronal differentiation and its molecular pathogenesis after hypoxic-ischemic brain damage in neonatal rats remains unclear. This study investigated the effects of GSK-3β inhibitor (TWS119) on cell cycle regulatory proteins, a neuronal differentiation factor (CEND1), maturation neurons, T-box brain transcription factor 1 (TBR1)-positive neurons to clarify the mechanisms of hypoxic-ischemic brain damage in neonatal rats. We used hypoxic-ischemic Sprague-Dawley neonatal rats with brain damage as models. These rats were used for investigating the effect of GSK-3β on cell cycle regulatory proteins, neuronal differentiation factor (CEND1), maturation neurons, TBR1-positive neurons by western blot and immunofluorescence. Cyclin D1 (a positive cell cycle regulator) expression decreased, and p21 (a negative cell cycle regulator) expression increased in the TWS119 group compared to the hypoxia-ischemia (HI) group 7 days after HI. Additionally, compared to the HI group, TWS119 treatment up-regulated CEND1 expression and promoted neuronal differentiation and cortex development based on NeuN and TBR1 expression. Our study suggests that the GSK-3β inhibitor TWS119 promotes neuronal differentiation after hypoxic-ischemic brain damage in neonatal rats by inhibiting cell cycle pathway.

Abstract
BACKGROUND A consistent connection has been increasingly reported between rheumatoid arthritis (RA), insulin resistance (IR), and type 2 diabetes (T2D). The β-cell apoptosis induced by pro-inflammatory cytokines, which could be exaggerated in the context of RA, is associated with increased expression pro-apoptotic proteins, which is dependent on JAnus Kinase/Signal Transducer and Activator of Transcription (JAK/STAT) activation. On these bases, we aimed to evaluate if the administration of tofacitinib, a potent and selective JAK inhibitor, could simultaneously improve glycaemic parameters and inflammatory markers in patients with RA and comorbid T2D. METHODS The primary endpoint was the change in the 1998-updated homeostatic model assessment of IR (HOMA2-IR) after 6 months of treatment with tofacitinib in RA patients with T2D. Consecutive RA patients with T2D diagnosis were included in this proof-of-concept, open, prospective, clinical study, which was planned before the recent emergence of safety signals about tofacitinib. Additional endpoints were also assessed regarding RA disease activity and metabolic parameters. RESULTS Forty consecutive RA patients with T2D were included (female sex 68.9%, mean age of 63.4 ± 9.9 years). During 6-month follow-up, a progressive reduction of HOMA2-IR was observed in RA patients with T2D treated with tofacitinib. Specifically, a significant effect of tofacitinib was shown on the overall reduction of HOMA2-IR (β = - 1.1, p = 0.019, 95%CI - 1.5 to - 0.76). Also, HOMA2-β enhanced in these patients highlighting an improvement of insulin sensitivity. Furthermore, although a longer follow-up is required, a trend in glycated haemoglobin reduction was also recorded. The administration of tofacitinib induced an improvement in RA disease activity, and a significant reduction of DAS28-CRP and SDAI was observed; 76.8% of patients achieved a good clinical response. In this study, no major adverse events (AEs) were retrieved without the identification of new safety signals. Specifically, no life-threatening AEs and cardiovascular and/or thromboembolic events were recorded. CONCLUSIONS The administration of tofacitinib in RA with T2D led to a simultaneous improvement of IR and inflammatory disease activity, inducing a "bidirectional" benefit in these patients. However, further specific designed and powered studies are warranted to entirely evaluate the metabolic effects of tofacitinib in RA patients with T2D.

Abstract
Avapritinib is the only potent and selective inhibitor approved for the treatment of D842V-mutant gastrointestinal stromal tumors (GIST), the most common primary mutation of the platelet-derived growth factor receptor α (PDGFRA). The approval was based on the NAVIGATOR trial, which revealed overall response rates of more than 90%. Despite this transformational activity, patients eventually progress, mostly due to acquired resistance mutations or following discontinuation due to neuro-cognitive side effects. These patients have no therapeutic alternative and face a dismal prognosis. Notable, little is known about this drug's binding mode and its medicinal chemistry development, which is instrumental for the development of the next generation of drugs. Against this background, we solve the crystal structures of avapritinib in complex with wild-type and mutant PDGFRA and stem cell factor receptor (KIT), which provide evidence and understanding of inhibitor binding and lead to the identification of a sub-pocket (Gα-pocket). We utilize this information to design, synthesize and characterize avapritinib derivatives for the determination of key pharmacophoric features to overcome drug resistance and limit potential blood-brain barrier penetration.

Abstract
The main challenges in the use of immune checkpoint inhibitors (ICIs) are ascribed to the immunosuppressive tumor microenvironment and the lack of sufficient infiltration of activated CD8+ T cells. Transforming the tumor microenvironment (TME) from "cold" to "hot" and thus more likely to potentiate the effects of ICIs is a promising strategy for cancer treatment. We found that the selective BCL-2 inhibitor APG-2575 can enhance the antitumor efficacy of anti-PD-1 therapy in syngeneic and humanized CD34+ mouse models. Using single-cell RNA sequencing, we found that APG-2575 polarized M2-like immunosuppressive macrophages toward the M1-like immunostimulatory phenotype with increased CCL5 and CXCL10 secretion, restoring T-cell function and promoting a favorable immunotherapy response. Mechanistically, we demonstrated that APG-2575 directly binds to NF-κB p65 to activate NLRP3 signaling, thereby mediating macrophage repolarization and the activation of proinflammatory caspases and subsequently increasing CCL5 and CXCL10 chemokine production. As a result, APG-2575-induced macrophage repolarization could remodel the tumor immune microenvironment, thus improving tumor immunosuppression and further enhancing antitumor T-cell immunity. Multiplex immunohistochemistry confirmed that patients with better immunotherapeutic efficacy had higher CD86, p-NF-κB p65 and NLRP3 levels, accompanied by lower CD206 expression on macrophages. Collectively, these data provide evidence that further study on APG-2575 in combination with immunotherapy for tumor treatment is required.

Abstract
OBJECTIVES To explore the clinical efficacy and safety of generic tofacitinib vs brand name tofacitinib in patients with rheumatoid arthritis (RA) in a single-center comparative study based on a prospective real-world cohort. METHODS Patients with RA receiving tofacitinib, either generic (Kelejia) or branded (Xeljanz), from March 2017, to December 31, 2022, were enrolled. The primary outcome was the simplified disease activity index (SDAI)-defined remission rate at month 6. Secondary outcomes included the rates of remission and low disease activity defined by other composite scores; European Alliance of Associations for Rheumatology response rate, and ultrasonic synovitis scores at months 1, 3, 6, and 12. Cost-effectiveness was investigated. Propensity score-based inverse probability of treatment weighting was adopted to reduce selection bias. RESULTS A total of 204 patients were enrolled: 59 in the generic group and 145 in the branded group. An SDAI-defined remission was achieved in 41.1% and 39.2% of patients in the generic and branded groups, respectively, at month 6 (P=.85). Rates of remission and low disease activity achievement, changes in clinical disease activity scores, and power Doppler and gray scale synovitis scores at months 1, 3, 6, and 12 were comparable between the 2 groups. Similar proportions of patients in the groups achieved moderate/good response at months 1, 3, 6, and 12. Rates of drug retention and adverse effects were also similar in the 2 groups. Both Kelejia and Xeljanz were cost-effective, but Kelejia had a lower average cost-effectiveness ratio. CONCLUSION Generic tofacitinib (Keljia) had equivalent clinical efficacy and safety and better cost-effectiveness compared with its originator (Xeljanz).

Abstract
BACKGROUND Statins reduce cardiovascular events and may improve bone mineral density. METHODS We conducted a sub-analysis of a randomized clinical trial that investigated the differential effect of moderate vs intensive low-density lipoprotein cholesterol (LDL-C) lowering therapies on coronary artery calcium (CAC) scores, and used the acquired images to assess the change in radiological attenuation of selected thoracic vertebrae. Baseline and 12-month unenhanced chest CT scans were performed in 420 hyperlipidemic, postmenopausal women randomized to atorvastatin (ATV) 80 mg/day or pravastatin (PRV) 40 mg/day in the Beyond Endorsed Lipid Lowering with Electron Beam Tomography Scanning (BELLES) trial. Bone attenuation was measured in three contiguous thoracic vertebrae at baseline and 12 months. RESULTS There were no differences in baseline demographic and clinical characteristics between treatment arms. The median percent lowering (interquartile range) in LDL-C was significantly greater with ATV than PRV [-53 (-69 to 20)% vs -28 (-55 to 74)%, p < 0.001], although the CAC score change was similar [12 (-63 to 208)% vs 13 (-75 to 358)%; p = 0.44]. At follow-up, the median bone attenuation loss was significantly greater with PRV than with ATV [-2.6 (-27 to 11)% vs 0 (-11 to 25)%; p < 0.001]. The attenuation loss in the PRV group was comparable to that of a historical untreated general population sample. In the entire cohort, the changes in LDL-C and total cholesterol were inversely correlated with bone attenuation change (p < 0.01). In adjusted multivariable linear regression analyses, race and percent change in LDL-C were independent predictors of bone attenuation change. Age, body mass index, history of smoking, diabetes mellitus, hypertension, peripheral vascular disease, or hormone replacement therapy did not affect percent change in BMD. CONCLUSIONS These findings support the hypothesis that there is an interaction between bone and cardiometabolic health and that intensive lipid lowering has a beneficial effect on bone health.

Abstract
BACKGROUND Sunitinib (SUN) malate is an oral, multitargeted, tyrosine kinase inhibitor approved for the treatment of metastatic renal cell carcinoma, imatinib-resistant or imatinib-intolerant gastrointestinal stromal tumors, and pancreatic neuroendocrine tumors. SUN has a narrow therapeutic window and high variability in interpatient pharmacokinetic parameters. Clinical detection methods for SUN and N -desethyl SUN limit the application of SUN to therapeutic drug monitoring. All published methods for quantifying SUN in human plasma require strict light protection to avoid light-induced isomerism or the use of additional quantitative software. To avoid these difficult processes in clinical routines, the authors propose a novel method that merges the peaks of the E -isomer and Z -isomer of SUN or N -desethyl SUN into a single peak. METHODS The E -isomer and Z -isomer peaks of SUN or N -desethyl SUN were merged into a single peak by optimizing the mobile phases to decrease the resolution of the isomers. A suitable chromatographic column was selected to obtain a good peak shape. Thereafter, the conventional and single-peak methods (SPM) were simultaneously validated and compared according to the guidelines published by the Food and Drug Administration in 2018 and the Chinese Pharmacopoeia in 2020. RESULTS The verification results showed that the SPM was superior to the conventional method in the matrix effect and met the requirements for biological sample analysis. SPM was then applied to detect the total steady-state concentration of SUN and N -desethyl SUN in tumor patients who received SUN malate. CONCLUSIONS The established SPM makes the detection of SUN and N -desethyl SUN easier and faster without light protection or extra quantitative software, making it more appropriate for routine clinical use. The clinical application results showed that 12 patients took 37.5 mg per day, with a median total trough steady-state concentration of 75.0 ng/mL.

Abstract
BACKGROUND Famitinib, the novel oral multitargeting tyrosine kinase inhibitor, was developed for treatment of patients with advanced solid cancer. This investigation assessed the pharmacokinetic (PK) effects of itraconazole, an officially recommended CYP3A4 strong inhibitor, on famitinib and its metabolite (SHR116637). METHODS A single-center, single-arm, open-label, and fixed sequence study was conducted in 22 healthy subjects. Famitinib was administered as a single oral 15 mg on Day1. Itraconazole 200 mg once daily was given from Day12 to Day24, concomitantly with famitinib on Day15 and for follow-up during Day30 to Day32. Blood sampling followed each famitinib dosage for PK analysis of famitinib and SHR116637. Safety and tolerability were also assessed throughout the treatment. RESULTS Cmax, AUC0-t and AUC0-∞ were raised by 40.6%, 77.7% and 81.6%, respectively, and t1/2 was prolonged from 36.08 hours to 48.24 hours for famitinib. In contrast, Cmax, AUC0-t and AUC0-∞ were reduced by 63.5%, 42.6%, and 39.0%, respectively, for SHR116637. Eight (36.4%) subjects reported seventeen treatments that emerged adverse events (all grade 1-2 in severity) all recovered at follow-up period. CONCLUSIONS Single oral dose of 15 mg famitinib and co-therapy with 200 mg intraconazole were safe and well tolerated in healthy subjects. Famitinib should be avoided in conjunction with strong CYP3A inhibitors if possible. TRIAL REGISTRATION This trial was registered at http://www.chinadrugtrials.org.cn/index.html.

Abstract
BACKGROUND We compared the efficacy and safety of low-intensity atorvastatin and ezetimibe combination therapy with moderate-intensity atorvastatin monotherapy in patients requiring cholesterol-lowering therapy. METHODS At 19 centers in Korea, 290 patients were randomized to 4 groups: atorvastatin 5 mg and ezetimibe 10 mg (A5E), ezetimibe 10 mg (E), atorvastatin 5 mg (A5), and atorvastatin 10 mg (A10). Clinical and laboratory examinations were performed at baseline, and at 4-week and 8-week follow-ups. The primary endpoint was percentage change from baseline in low-density lipoprotein (LDL) cholesterol levels at the 8-week follow-up. Secondary endpoints included percentage changes from baseline in additional lipid parameters. RESULTS Baseline characteristics were similar among the study groups. At the 8-week follow-up, percentage changes in LDL cholesterol levels were significantly greater in the A5E group (49.2%) than in the E (18.7%), A5 (27.9%), and A10 (36.4%) groups. Similar findings were observed regarding the percentage changes in total cholesterol, non-high-density lipoprotein cholesterol, and apolipoprotein B levels. Triglyceride levels were also significantly decreased in the A5E group than in the E group, whereas high-density lipoprotein levels substantially increased in the A5E group than in the E group. In patients with low- and intermediate-cardiovascular risk, 93.3% achieved the target LDL cholesterol levels in the A5E group, 40.0% in the E group, 66.7% in the A5 group, and 92.9% in the A10 group. In addition, 31.4% of patients in the A5E group, 8.1% in E, 9.7% in A5, and 7.3% in the A10 group reached the target levels of both LDL cholesterol < 70 mg/dL and reduction of LDL ≥ 50% from baseline. CONCLUSIONS The addition of ezetimibe to low-intensity atorvastatin had a greater effect on lowering LDL cholesterol than moderate-intensity atorvastatin alone, offering an effective treatment option for cholesterol management, especially in patients with low and intermediate risks.

Abstract
Lower extremity deep venous thrombosis (LEDVT) affects patient's quality of life for a long time, and even causes pulmonary embolism, which threatens human health. Current anticoagulant drugs in clinical treatment are hampered by the risk of bleeding due to poor targeting and low drug penetration. Here, we used platelet (PLT)-like biological targeting to enhance the delivery and accumulation of nanomedicines in thrombus and reduce the risk of bleeding. Meanwhile, the parallel strategy of "thrombus thermal ablation and anticoagulation" was applied to increase the permeability of drugs in thrombus and achieve the optimal antithrombotic effect. Polypyrrole (PPy) and rivaroxban (Riv, an anticoagulant drug) were co-assembled into platelet membrane-coated nanoparticles (NPs), PLT-PPy/Riv NPs, which actively targeted the thrombotic lesion at multiple targets in the platelet membrane and were thermally and drug-specific thrombolysed by 808 nm laser irradiation. The combination therapy resulted in up to 90% thrombolysis in a femoral vein thrombosis model compared to single phototherapy or drug therapy. The results showed that the nanoformulation provided a new direction for remote precise and controlled sustained thrombolysis, which was in line with the trend of nanomedicine towards clinical translation.

Abstract
BACKGROUND Vonoprazan is a new potassium-competitive acid blocker (P-CAB) that was recently approved by the FDA. It is associated with a fast onset of action and a longer acid inhibition time. Vonoprazan-containing therapy for helicobacter pylori eradication is highly effective and several studies have demonstrated that a vonoprazan-antibiotic regimen affects gut microbiota. However, the impact of vonoprazan alone on gut microbiota is still unclear.Please check and confirm the authors (Maria Cristina Riascos, Hala Al Asadi) given name and family name are correct. Also, kindly confirm the details in the metadata are correct.Yes they are correct. METHODS: We conducted a prospective randomized 12-week experimental trial with 18 Wistar rats. Rats were randomly assigned to one of 3 groups: (1) drinking water as negative control group, (2) oral vonoprazan (4 mg/kg) for 12 weeks, and (3) oral vonoprazan (4 mg/kg) for 4 weeks, followed by 8 weeks off vonoprazan. To investigate gut microbiota, we carried out a metagenomic shotgun sequencing of fecal samples at week 0 and week 12.Please confirm the inserted city and country name is correct for affiliation 2.Yes it's correct. RESULTS For alpha diversity metrics at week 12, both long and short vonoprazan groups had lower Pielou's evenness index than the control group (p = 0.019); however, observed operational taxonomic units (p = 0.332) and Shannon's diversity index (p = 0.070) were not statistically different between groups. Beta diversity was significantly different in the three groups, using Bray-Curtis (p = 0.003) and Jaccard distances (p = 0.002). At week 12, differences in relative abundance were observed at all levels. At phylum level, short vonoprazan group had less of Actinobacteria (log fold change = - 1.88, adjusted p-value = 0.048) and Verrucomicrobia (lfc = - 1.76, p = 0.009).Please check and confirm that the author (Ileana Miranda) and their respective affiliation 3 details have been correctly identified and amend if necessary.Yes it's correct. At the genus level, long vonoprazan group had more Bacteroidales (lfc = 5.01, p = 0.021) and Prevotella (lfc = 7.79, p = 0.001). At family level, long vonoprazan group had more Lactobacillaceae (lfc = 0.97, p = 0.001), Prevotellaceae (lfc = 8.01, p < 0.001), and less Erysipelotrichaceae (lfc = - 2.9, p = 0.029). CONCLUSION This study provides evidence that vonoprazan impacts the gut microbiota and permits a precise delineation of the composition and relative abundance of the bacteria at all different taxonomic levels.

Abstract
The runt-related transcription factor (RUNX) family is known to play important roles in the progression of cancer. Conjugate 1, which covalently binds to the RUNX-binding sequences, was reported to inhibit the binding of RUNX proteins to their target sites and suppress cancer growth. Here, we evaluated the anticancer effects of 1 and its analogs 2-4 against p53-mutated PANC-1 pancreatic cancer cells. We found that they possessed different DNA-alkylating properties in vitro. And conjugates 1-3 were shown to have anticancer effects by inducing apoptosis in PANC-1 cells. Furthermore, conjugates 2 and 3 suppressed cancer growth in PANC-1 xenograft mice, with activity equivalent to a 50-fold dose of gemcitabine. Especially, 3 showed the highest alkylation efficiency, specificity, and better anticancer effects against pancreatic cancer than 1 in vivo without significant body weight loss. Our results revealed the potential of our compounds as new candidates for cancer therapy.

Abstract
PURPOSE For many years, statins have been the most commonly used drugs in cholesterol-lowering therapy. In addition to these therapeutic effects, statins exhibit other, pleiotropic effects that can be beneficial, but also harmful to cells and tissues. The aim of this research was to determine and compare the pleiotropic effects of structurally different statins: atorvastatin, simvastatin and rosuvastatin at different concentrations on hepatocellular carcinoma (HepG2) cells. MATERIALS AND METHODS The MTT assay was used to determine the cytotoxic effects of statins. The influence of statins on the production of reactive oxygen species (ROS) was determined by measuring fluorescent response of 2,7-dichlorofluorescein diacetate (DCFH-DA). The effect of statins on glucose production and excretion was determined with glucose production assay. RESULTS The obtained results confirmed that all tested statins exhibit cytotoxic effects, increase the production of ROS as well as the production and excretion of glucose from HepG2 cells. It was observed that all the mentioned effects are more pronounced with lipophilic statins, atorvastatin and simvastatin compared to hydrophilic rosuvastatin. CONCLUSION The less pronounced pleiotropic effects of rosuvastatin on HepG2 cells are probably due to differences in structure and solubility compared to atorvastatin and simvastatin. Transporter-dependent and a slower influx of rosuvastatin into cells compared to the tested lipophilic statins probably lead to a weaker accumulation of rosuvastatin in HepG2 cells, which results in less pronounced pleiotropic effects compared to lipophilic atorvastatin and simvastatin.

Abstract
PURPOSE OF REVIEW Gepants are small molecules that antagonize calcitonin gene-related peptide (CGRP) receptors. Due to their favorable side effect profile and versatility in treating headaches acutely and preventively, gepants are preferred over triptans. We will cover the indications for the four FDA-approved gepants in adults: rimegepant, atogepant, ubrogepant, and zavegepant. This review will illustrate how gepants will continue to revolutionize the acute and preventive treatment of headaches. RECENT FINDINGS Gepants are now available in oral tablet, dissolving tablet, and intra-nasal spray formulations. Recent studies have shown promising utility in treating the pre-headache or prodromal phase. They have favorable tolerability, no evidence for association with medication overuse, and remain a safer alternative in those who have cerebrovascular risk factors. Additional research is needed to explore occurrence of Raynaud's phenomenon in participants treated with gepants, as it has been associated with CGRP monoclonal antibodies, but are not extensively studied in gepants. Gepants are expected to play a significant role in the next generation of migraine treatments.

Abstract
ABSTRACT Acute migraine affects millions of people and is one of the most common primary care complaints in the United States. Available first-line abortive treatments are limited and vary in efficacy. Newer medications such as calcitonin gene-related peptide (CGRP) receptor antagonists may be a useful alternative. This article describes the use of ubrogepant, a new CGRP receptor antagonist, in a patient with contraindications to traditional medications used for acute migraine.

Abstract
Futibatinib is a covalently binding FGFR1-4 inhibitor that received US Food and Drug Administration approval for the treatment of patients with previously treated, advanced intrahepatic cholangiocarcinoma harboring FGFR2 gene fusions/rearrangements. This phase I trial evaluated the pharmacokinetics (PKs), safety, and tolerability of futibatinib in subjects with impaired hepatic function and matched healthy volunteers. Twenty-two subjects with hepatic impairment (8 mild [Child-Pugh 5-6], 8 moderate [7-9], and 6 severe [10-15]) and 16 matched healthy control subjects received a single oral dose of futibatinib 20 mg. Futibatinib PKs were compared between subjects with mild/moderate/severe hepatic impairment and each corresponding control cohort and the overall control cohort. Relationships between futibatinib PKs and Child-Pugh scores and liver function tests were examined via scatter/regression plots. Compared with matched controls, the area under the plasma concentration-time curve from time zero to infinity increased by 21%/20%/18% and the maximum plasma concentration (Cmax ) increased by 43%/15%/10% in subjects with mild/moderate/severe hepatic impairment, respectively. Changes were not considered clinically relevant: geometric mean ratios were within 80%-125%, except for Cmax in subjects with mild hepatic impairment (143%). No obvious trends were observed among futibatinib PK parameters versus Child-Pugh scores, bilirubin, albumin, international normalized ratio, and aspartate aminotransferase (all p > 0.05). Futibatinib was well-tolerated, with only four grade 1 treatment-emergent adverse events (mild hepatic impairment = 2 and control = 2). The results demonstrate that futibatinib dose adjustments due to mild/moderate/severe hepatic impairment are not necessary in patients receiving futibatinib 20 mg daily.

Abstract
Pancreatic cancer is a highly aggressive cancer, and is primarily treated with gemcitabine, with increasing resistance. SIRT6 as a member of sirtuin family plays important roles in lifespan and diverse diseases, such as cancer, diabetes, inflammation and neurodegenerative diseases. Considering the role of SIRT6 in the cytoprotective effect, it might be a potential anticancer drug target, and is associated with resistance to anticancer therapy. However, very few SIRT6 inhibitors have been reported. Here, we reported the discovery of a pyrrole-pyridinimidazole derivative, 8a, as a new non-competitive SIRT6 inhibitor, and studied its roles and mechanisms in the antitumor activity and sensitization of pancreatic cancer to gemcitabine. Firstly, we found a potent SIRT6 inhibitor compound 8a by virtual screening and identified by molecular and cellular SIRT6 activity assays. 8a could effectively inhibit SIRT6 deacetylation activity with IC50 values of 7.46 ± 0.79 μM in FLUOR DE LYS assay, and 8a significantly increased the acetylation levels of H3 in cells. Then, we found that 8a could inhibit the cell proliferation and induce cell apoptosis in pancreatic cancer cells. We further demonstrate that 8a sensitize pancreatic cancer cells to gemcitabine via reversing the activation of PI3K/AKT/mTOR and ERK signaling pathways induced by gemcitabine and blocking the DNA damage repair pathway. Moreover, combination of 8a and gemcitabine induces cooperative antitumor activity in pancreatic cancer xenograft model in vivo. Overall, we demonstrate that 8a, a novel SIRT6 inhibitor, could be a promising potential drug candidate for pancreatic cancer treatment.

Abstract
AIM This systematic review and meta-analysis was conducted to evaluate the efficacy and safety of 4 mg saroglitazar treatment in patients with non-alcoholic fatty liver disease (NAFLD) or non-alcoholic steatohepatitis (NASH). METHODS PubMed, Embase, Scopus, Cochrane CENTRAL, medRxiv (pre-print), bioRxiv (pre-print), and ClinicalTrials.gov databases were searched for relevant studies. The primary outcome was the change in the serum alanine transaminase (ALT) level. The secondary outcomes were changes in liver stiffness, liver function test parameters, and metabolic parameters. Pooled mean differences were calculated using random-effects models. RESULTS Of 331 studies that were screened, ten were included. Treatment with adjunct saroglitazar showed a reduction in ALT [mean difference: 26.01 U/L (95% CI: 10.67 to 41.35); p = 0.009; i2: 98%; moderate GRADE evidence] and aspartate transaminase [mean difference: 19.68 U/L (95% CI: 8.93 to 30.43); p<0.001; i2: 97%; moderate GRADE evidence] levels. There was a significant improvement in liver stiffness [mean difference: 2.22 kPa (95% CI: 0.80 to 3.63); p = 0.002; i2: 99%; moderate GRADE evidence]. There were significant improvements in glycated hemoglobin [mean difference: 0.59% (95% CI: 0.32 to 0.86); p<0.001; i2: 78%; moderate GRADE evidence], total cholesterol [mean difference: 19.20 (95% CI: 1.54 to 36.87); p = 0.03; i2: 95%; moderate GRADE evidence], and triglyceride [mean difference: 105.49 mg/dL (95% CI: 11.18 to 199.80); p = 0.03; i2: 100%; moderate GRADE evidence] levels. Saroglitazar treatment was safe. CONCLUSION Treatment with adjunct 4 mg saroglitazar could significantly improve liver enzymes, reduce liver stiffness, and improve metabolic parameters (serum glucose and lipid profile) in patients with NAFLD or NASH.

Abstract
BACKGROUND Atogepant is an oral, small-molecule, calcitonin gene-related peptide receptor antagonist for the preventive treatment of episodic migraine. METHODS In this 52-week, multicenter, randomized, open-label trial, adults with 4-14 monthly migraine days received atogepant 60 mg once-daily or standard care. Health outcome endpoints collected from participants randomized to atogepant included change from baseline in Migraine-Specific Quality of Life Questionnaire version 2.1 (MSQ v2.1) Role Function-Restrictive (RFR), Role Function-Preventive (RFP) and Emotional Function (EF) domain scores, change in Activity Impairment in Migraine-Diary (AIM-D) Performance of Daily Activities (PDA) and Physical Impairment (PI) domain scores, and change in Headache Impact Test-6 (HIT-6) total score. RESULTS Of 744 randomized participants, 521 received atogepant 60 mg in the modified intent-to-treat population. Least-squares mean changes from baseline in MSQ-RFR score were 30.02 (95% confidence interval = 28.16-31.87) at week 12 and 34.70 (95% confidence interval = 32.74-36.66) at week 52. Improvements were also observed in other MSQ domains, AIM-D PDA, PI and HIT-6 total scores. A ≥5-point improvement from baseline in HIT-6 score was observed in 59.9% of participants at week 4 and 80.8% of participants at week 52. CONCLUSION Over 52 weeks, atogepant 60 mg once-daily was associated with sustained improvements in quality of life and reductions in activity impairment and headache impact.Trial Registration: NCT03700320.

Abstract
Aim: 20 mg of vonoprazan (VPZ20) is recommended in most countries to treat erosive esophagitis (EE). Whether other doses of vonoprazan, such as 5 mg (VPZ5), 10 mg (VPZ10), 20 mg (VPZ20), and 40 mg (VPZ40) are more effective is unknown. Materials & methods: Three databases were electronically searched to identify studies published before November 2021. Network meta-analysis was performed using STATA 14.0. Results: VPZ20 and VPZ40 were comparable to PPI, VPZ5 and VPZ10 in 4- and 8-week healing rates, and this was also detected in patients with refractory EE. All regimens resulted in similar treatment-emergent adverse events (TEAEs). However, VPZ40 ranked first for healing rate and TEAEs; however, VPZ20 ranked worst for TEAEs. Conclusion: Different doses of VPZ are comparable in efficacy and safety, but VPZ40 may be best in both effectiveness and safety.

Abstract
Proton pump inhibitors (PPIs) are a mainstay treatment for acid peptic disorders such as gastroesophageal reflux disease (GERD). Although PPIs are considered first-line medications for acid suppression, they have notable limitations such as requiring acid-mediated activation, short half-life and duration of action, and metabolic variability. Fexuprazan is a newly developed potassium-competitive acid blocker (P-CAB), which inhibits acid generation and secretion in a competitive and reversible manner. Fexuprazan, like other P-CABs, has significantly different pharmacodynamic and pharmacokinetic properties than PPIs with potential advantages including rapid, robust, and durable acid suppression, lack of CYP2C19 metabolism, independence from food intake, and no requirement for activation into an active form. Completed clinical trials of fexuprazan have demonstrated comparable efficacy to PPIs for the healing of erosive esophagitis and relief of GERD-related esophageal symptoms without concerning safety signals. Ongoing clinical trials are evaluating fexuprazan for the prevention of NSAID-induced peptic ulcer disease, non-erosive GERD, and acute and chronic gastritis, as well as healing efficacy and maintenance of erosive esophagitis (EE). Fexuprazan is approved in South Korea for the treatment of EE and at the time of this writing is being considered for regulatory approval in several other countries. In this article, we summarize and discuss the pharmacology, efficacy, and safety of fexuprazan.

Abstract
In recent years, strategies targeting β-cell protection via autoimmune regulation have been suggested as novel and potent immunotherapeutic interventions against type 1 diabetes mellitus (T1D). Here, we investigated the potential of toceranib (TOC), a receptor-type tyrosine kinase (RTK) inhibitor used in veterinary practice, to ameliorate T1D. TOC reversed streptozotocin-induced T1D and improved the abnormalities in muscle and bone metabolism characteristic of T1D. Histopathological examination revealed that TOC significantly suppressed β-cell depletion and improved glycemic control with restoration of serum insulin levels. However, the effect of TOC on blood glucose levels and insulin secretion capacity is attenuated in chronic T1D, a more β-cell depleted state. These findings suggest that TOC improves glycemic control by ameliorating the streptozotocin-induced decrease in insulin secretory capacity. Finally, we examined the role of platelet-derived growth factor receptor (PDGFR) inhibition, a target of TOC, and found that inhibition of PDGFR reverses established T1D in mice. Our results show that TOC reverses T1D by preserving islet function via inhibition of RTK. The previously unrecognized pharmacological properties of TOC have been revealed, and these properties could lead to its application in the treatment of T1D in the veterinary field.

Abstract
PURPOSE Diabetes and dyslipidemia are leading causes of mortality and morbidity. According to international guidelines, statins are the cornerstone of treatment in patients with diabetes and/or dyslipidemia. However, statins and antidiabetic agents have opposite pharmacological effects, because statins, particularly atorvastatin and rosuvastatin, impair glucose homeostasis, increasing the risk of new-onset diabetes, whereas antidiabetic drugs improve glycemic homeostasis. The aim of this study was to investigate the effect of atorvastatin, rosuvastatin, and pitavastatin on glucose homeostasis in patients with type 2 diabetes mellitus (T2DM) and dyslipidemia during stable treatment with hypoglycemic drugs. MATERIALS AND METHODS The study was conducted as a pilot, prospective, randomized, open label, parallel group with blinded-endpoints (PROBE) study. Of 180 recruited patients with T2DM and dyslipidemia, 131 were randomized to atorvastatin (n=44), rosuvastatin (n=45), and pitavastatin (n=42) and treated for 6 months. RESULTS Fasting plasma glucose (FPG) marginally decreased in patients assigned to atorvastatin (-3.5 mg/dL, p=0.42) and rosuvastatin (-6.5 mg/dL, p=0.17), while it decreased much more in patients treated with pitavastatin (-19.0 mg/dL, p<0.001). Mean glycated hemoglobin A1c (HbA1c ) values remained unchanged during treatment with atorvastatin (-0.10%, p=0.53) and rosuvastatin (0.20%, p=0.40), but were significantly reduced with pitavastatin (-0.75%, p=0.01). Atorvastatin, rosuvastatin, and pitavastatin significantly lowered (p<0.001) plasma levels of total cholesterol, low-density lipoprotein-cholesterol, and triglycerides, while high-density lipoprotein-cholesterol (HDL-C) levels increased significantly (p=0.04) only in the pitavastatin group. CONCLUSION The results of the present study suggest that pitavastatin affects FPG and HbA1c less than atorvastatin and rosuvastatin in patients with T2DM and concomitant dyslipidemia. Lipid-lowering efficacies were not significantly different among the three statins, with the exception of HDL-C, which increased significantly with pitavastatin. Although the pharmacological mechanism of pitavastatin on glucose homeostasis in patients with T2DM during stable antidiabetic therapy is not known, it can be assumed that pitavastatin has less drug interaction with hypoglycemic agents or that it increases plasma levels of adiponectin.

Abstract
Currently, renal cell carcinoma (RCC) is the most prevalent type of kidney cancer. Targeted therapy has replaced radiation therapy and chemotherapy as the main treatment option for RCC due to the lack of significant efficacy with these conventional therapeutic regimens. Sunitinib, a drug used to treat gastrointestinal tumors and renal cell carcinoma, inhibits the tyrosine kinase activity of a number of receptor tyrosine kinases, including vascular endothelial growth factor receptor (VEGFR), platelet-derived growth factor receptor (PDGFR), c-Kit, rearranged during transfection (RET) and fms-related receptor tyrosine kinase 3 (Flt3). Although sunitinib has been shown to be efficacious in the treatment of patients with advanced RCC, a significant number of patients have primary resistance to sunitinib or acquired drug resistance within the 6-15 months of therapy. Thus, in order to develop more efficacious and long-lasting treatment strategies for patients with advanced RCC, it will be crucial to ascertain how to overcome sunitinib resistance that is produced by various drug resistance mechanisms. In this review, we discuss: 1) molecular mechanisms of sunitinib resistance; 2) strategies to overcome sunitinib resistance and 3) potential predictive biomarkers of sunitinib resistance.

Abstract
BACKGROUND Rheumatoid arthritis (RA), a chronic systemic autoimmune disease, is characterized by synovitis and progressive damage to the bone and cartilage of the joints, leading to disability and reduced quality of life. This study was a randomized clinical trial comparing the outcomes between withdrawal and dose reduction of tofacitinib in patients with RA who achieved sustained disease control. METHODS The study was designed as a multicenter, open-label, randomized controlled trial. Eligible patients who were taking tofacitinib (5 mg twice daily) and had achieved sustained RA remission or low disease activity (disease activity score in 28 joints [DAS28] ≤3.2) for at least 3 months were enrolled at six centers in Shanghai, China. Patients were randomly assigned (1:1:1) to one of three treatment groups: continuation of tofacitinib (5 mg twice daily); reduction in tofacitinib dose (5 mg daily); and withdrawal of tofacitinib. Efficacy and safety were assessed up to 6 months. RESULTS Overall, 122 eligible patients were enrolled, with 41 in the continuation group, 42 in the dose-reduction group, and 39 in the withdrawal group. After 6 months, the percentage of patients with a DAS28-erythrocyte sedimentation rate (ESR) of <3.2 was significantly lower in the withdrawal group than that in the reduction and continuation groups (20.5%, 64.3%, and 95.1%, respectively; P < 0.0001 for both comparisons). The average flare-free time was 5.8 months for the continuation group, 4.7 months for the dose reduction group, and 2.4 months for the withdrawal group. CONCLUSION Withdrawal of tofacitinib in patients with RA with stable disease control resulted in a rapid and significant loss of efficacy, while standard or reduced doses of tofacitinib maintained a favorable state.

Abstract
PURPOSE Vonoprazan (VPZ), a reversible H+-K+ ATPase inhibitor, has a relatively fast and sustained acid-suppression action that is unaffected by diet or gene polymorphisms. Several randomized controlled trials have evaluated the difference in the eradication rate of Helicobacter pylori (HP) between VPZ-based and proton pump inhibitor (PPI)-based regimens. The present review aimed to (1) evaluate the efficacy, safety, and compliance of VPZ-based regimens compared with those of PPI-based regimens as first-line treatments for HP infection and (2) perform a subgroup analysis to examine the influence of differences in clarithromycin-resistance status, treatment duration, treatment regimens, and research region on treatment outcomes. METHODS We conducted a systematic literature search on PubMed, Embase, Cochrane Library, Web of Science, and ChiCTR Register. Systematic searches, study selection, data extraction, risk of bias assessment, and statistical analysis were performed according to pre-registered protocol on the PROSPERO (CRD42022336608). RESULTS Eight studies and 2956 HP-infected patients were enrolled. Only first-line therapy and RCT study were considered. VPZ-based group had a superior eradication efficacy compared to PPI-based group by intention-to-treat (ITT) (pooled risk ratio (RR): 1.14, 95% CI: 1.08-1.21, p < 0.00001) and per-protocol analysis (pooled RR: 1.13, 95% CI: 1.07-1.20, p < 0.00001). This finding was further validated by subgroup analysis depending on treatment regimens, duration, region, and clarithromycin resistance. In addition, there was no significant difference in adverse events (p = 0.33) and compliances (p = 0.30) between the regimens. CONCLUSION The VPZ-based regimens showed a superior eradication efficacy compared to the already frequently used PPI-based regimens. Furthermore, VPZ-based therapy showed comparable tolerability and incidence of adverse events.

Abstract
Prototheca bovis has been associated with several cases of mastitis in cattle but no record of intramammary infections has been reported in goats. This infection does not respond to available treatments and the disposal recommendation of affected animals cause great damage to the dairy industry. Alternatives for dealing with infections caused by Prototheca spp. are required worldwide. In vitro results suggest polypyrrole as promising molecule for combating this alga, because an algaecide effect was observed on tested Prototheca spp. isolates. Thus, this study evaluated goats as an experimental model for intramammary infection by P. bovis and a protocol for treating these animals with an intramammary polypyrrole solution. The possibility of P. bovis promoting an intramammary infection in goats was experimentally proven, demonstrating this species as an important model for studies involving algae mastitis. Furthermore, polypyrrole reduced the counts of Prototheca sp. in the analyzed samples, showing potential to fight this microorganism also in vivo. The results obtained in this study demonstrate the ability of P. bovis to colonize breast tissue in lactating goats and the highly soluble molecule of polypyrrole has potential use for the treatment of protothecosis.
