RESUMEN
BACKGROUND: The purpose of this study was to evaluate the efficacy and safety of fruquintinib-based therapy as a salvage therapy for patients with advanced or metastatic sarcoma, including soft tissue sarcoma (STS) and bone sarcoma. METHODS: Patients with advanced or metastatic sarcoma were divided into two groups. One group received fruquintinib monotherapy, while the other received fruquintinib combined therapy. Safety and efficacy of fruquintinib-based therapy were recorded and reviewed retrospectively, including progression-free survival (PFS), overall response rate (ORR), and adverse events (AEs). RESULTS: Between August 2021 and December 2022, 38 sarcoma patients were retrospectively included. A total of 14 patients received fruquintinib alone (including 6 STS and 8 bone sarcoma), while 24 were treated with fruquintinib combined therapy (including 2 STS and 22 bone sarcoma). The median follow-up was 10.2 months (95% CI, 6.4-11.5). For the entire population, the median PFS was 8.0 months (95% CI, 5.5-13.0). The ORR was 13.1%, while the disease control rate (DCR) was 86.8%. The univariate analysis showed that radiotherapy history (HR, 4.56; 95% CI, 1.70-12.24; p = 0.003), bone sarcoma (HR, 0.34; 95% CI, 0.14-0.87; p = 0.024), and treatment method of fruquintinib (HR, 0.36; 95% CI, 0.15-0.85; p = 0.021) were significantly associated with PFS. The multivariate analysis showed that patients without radiotherapy history were associated with a better PFS (HR, 3.71; 95% CI: 1.31-10.55; p = 0.014) than patients with radiotherapy history. Patients in combination group reported pneumothorax (8.3%), leukopenia (33.3%), thrombocytopenia (12.5%), diarrhea (4.2%), and anemia (4.2%) as the most frequent grade 3 or higher treatment-emergent AEs (TEAEs), while there was no severe TEAEs occurred in the monotherapy group. CONCLUSIONS: Fruquintinib-based therapy displayed an optimal tumor control and an acceptable safety profile in patients with advanced or metastatic sarcoma.

INTRODUCTION: The efficacy of multitarget neuroprotective drug DL-3-n-butylphthalide (NBP) in improving cognitive function has been confirmed in patients with vascular cognitive impairment without dementia. However, its efficacy in patients with symptomatic predementia phase of Alzheimer's disease remains uncertain. This study aims to evaluate the efficacy and safety of NBP in improving cognitive function in patients with mild cognitive impairment (MCI) through a clinical randomised controlled trail. METHODS AND ANALYSIS: This study is a 12-month, randomised, double-blind, placebo-controlled, multicentric trial, involving 270 patients with MCI. Subjects are randomly assigned to receive either NBP soft capsule (200 mg, three times per day) or placebo with an allocation ratio of 1:1. The efficacy and safety of NBP are assessed by comparing the results of neuropsychological, neuroimaging and laboratory tests between the two groups. The primary endpoint is the change in Alzheimer's Disease Assessment Scale-Cognitive Subscale after 12 months. All patients will be monitored for adverse events. ETHICS AND DISSEMINATION: This study involving human participants has been reviewed and approved by Ethics Committee of Xuan Wu Hospital (No.2017058). The participants provide their written informed consent to participate in this study. Results will be published in peer-reviewed medical journals and disseminated to healthcare professionals at local and international conferences. PROTOCOL VERSION: V 3.0, 3 September 2022.

Aim: The objective of this study was to compare adverse event (AE) management costs for fruquintinib, regorafenib, trifluridine/tipiracil (T/T) and trifluridine/tipiracil+bevacizumab (T/T+bev) for patients with metastatic colorectal cancer (mCRC) previously treated with at least two prior lines of therapy from the US commercial and Medicare payer perspectives. Materials & methods: A cost-consequence model was developed to calculate the per-patient and per-patient-per-month (PPPM) AE costs using rates of grade 3/4 AEs with incidence ≥5% in clinical trials, event-specific management costs and duration treatment. Anchored comparisons of AE costs were calculated using a difference-in-differences approach with best supportive care (BSC) as a common reference. AE rates and treatment duration were obtained from clinical trials: FRESCO and FRESCO-2 (fruquintinib), RECOURSE (T/T), CORRECT (regorafenib) and SUNLIGHT (T/T, T/T+bev). AE management costs for the commercial and Medicare perspectives were obtained from publicly available sources. Results: From the commercial perspective, the AE costs (presented as per-patient, PPPM) were: $4015, $1091 for fruquintinib (FRESCO); $4253, $1390 for fruquintinib (FRESCO-2); $17,110, $11,104 for T/T (RECOURSE); $9851, $4691 for T/T (SUNLIGHT); $8199, $4823 for regorafenib; and $11,620, $2324 for T/T+bev. These results were consistent in anchored comparisons: the difference-in-difference for fruquintinib based on FRESCO was -$1929 versus regorafenib and -$11,427 versus T/T; for fruquintinib based on FRESCO-2 was -$2257 versus regorafenib and -$11,756 versus T/T. Across all analyses, results were consistent from the Medicare perspective. Conclusion: Fruquintinib was associated with lower AE management costs compared with regorafenib, T/T and T/T+bev for patients with previously treated mCRC. This evidence has direct implications for treatment, formulary and pathways decision-making in this patient population.

The vascular endothelial growth factor pathway plays a key role in the pathogenesis of gastric cancer. In the multicenter, double-blind phase 3 FRUTIGA trial, 703 patients with advanced gastric or gastroesophageal junction adenocarcinoma who progressed on fluorouracil- and platinum-containing chemotherapy were randomized (1:1) to receive fruquintinib (an inhibitor of vascular endothelial growth factor receptor-1/2/3; 4 mg orally, once daily) or placebo for 3 weeks, followed by 1 week off, plus paclitaxel (80 mg/m2 intravenously on days 1/8/15 per cycle). The study results were positive as one of the dual primary endpoints, progression-free survival (PFS), was met (median PFS, 5.6 months in the fruquintinib arm versus 2.7 months in the placebo arm; hazard ratio 0.57; 95% confidence interval 0.48-0.68; P < 0.0001). The other dual primary endpoint, overall survival (OS), was not met (median OS, 9.6 months versus 8.4 months; hazard ratio 0.96, 95% confidence interval 0.81-1.13; P = 0.6064). The most common grade ≥3 adverse events were neutropenia, leukopenia and anemia. Fruquintinib plus paclitaxel as a second-line treatment significantly improved PFS, but not OS, in Chinese patients with advanced gastric or gastroesophageal junction adenocarcinoma and could potentially be another treatment option for these patients.

On November 8, 2023, the FDA approved fruquintinib, an inhibitor of vascular endothelial growth factor receptor (VEGFR)-1, -2, and -3, for the treatment of patients with metastatic colorectal cancer (mCRC) who have been previously treated with fluoropyrimidine-, oxaliplatin-, and irinotecan-based chemotherapy, an anti-VEGF therapy, and if RAS wild-type and medically appropriate, an anti-EGFR therapy. Approval was based on Study FRESCO-2, a globally conducted, double-blind, placebo-controlled randomized trial. The primary endpoint was overall survival (OS). The key secondary endpoint was progression-free survival. A total of 691 patients were randomly assigned (461 and 230 into the fruquintinib and placebo arms, respectively). Fruquintinib provided a statistically significant improvement in OS with a hazard ratio (HR) of 0.66 [95% confidence interval (CI), 0.55, 0.80; P < 0.001]. The median OS was 7.4 months (95% CI, 6.7, 8.2) in the fruquintinib arm and 4.8 months (95% CI, 4.0, 5.8) for the placebo arm. Adverse events observed were generally consistent with the known safety profile associated with the inhibition of VEGFR. The results of FRESCO-2 were supported by the FRESCO study, a double-blind, single-country, placebo-controlled, randomized trial in patients with refractory mCRC who have been previously treated with fluoropyrimidine-, oxaliplatin-, and irinotecan-based chemotherapy. In FRESCO, the OS HR was 0.65 (95% CI, 0.51, 0.83; P < 0.001). FDA concluded that the totality of the evidence from FRESCO-2 and FRESCO supported an indication for patients with mCRC with prior treatment with fluoropyrimidine, oxaliplatin-, and irinotecan-based chemotherapy, an anti-VEGF biological therapy, and if RAS wild-type and medically appropriate, an anti-EGFR therapy.

INTRODUCTION: Fruquintinib is approved in China for patients with metastatic colorectal cancer (CRC) who progressed after 2 lines of chemotherapy. This postmarketing study was conducted to evaluate the safety of fruquintinib in the Chinese population, including previously treated patients with advanced CRC and other solid tumors. METHODS: Patients in the first cycle of fruquintinib or expected to start fruquintinib within a week were enrolled. Fruquintinib was administrated according to the label or per physicians' discretion. Patient characteristics and safety information were collected at baseline, 1 month, and 6 months after consent (or 30 days after the last dose). RESULTS: Overall, 3005 patients enrolled between April 24, 2019 and September 27, 2022. All enrolled patients received at least one dose of fruquintinib. Most patients had metastases at baseline. The median age was 60 years. More than half (64.0%) of the patients started fruquintinib at 5 mg, and the median treatment exposure was 2.7 months. Nearly one-third (32.5%) of patients with CRC received fruquintinib with concomitant antineoplastic agents. Treatment-emergent adverse events (TEAEs) leading to dose modification were reported in 626 (20.8%) patients, and 469 (15.6%) patients experienced TEAEs leading to treatment discontinuation. The most common grade ≥ 3 TEAEs were hypertension (6.6%), palmar-plantar erythrodysesthesia syndrome (2.2%), and platelet count decreased (1.0%). Combination therapy did not lead to excessive toxicities. CONCLUSIONS: The safety profile of fruquintinib in the real world was generally consistent with that in clinical studies, and the incidence of TEAEs was numerically lower than known VEGF/VEGFR inhibitor-related AEs. Fruquintinib exhibited manageable safety and tolerability in Chinese patients in the real-world setting.

INTRODUCTION: Colorectal cancer (CRC) is the third most diagnosed cancer globally and despite therapeutic strides, the prognosis for patients with metastatic disease (mCRC) remains poor. Fruquintinib is an oral vascular endothelial growth factor receptor (VEGFR) tyrosine kinase inhibitor (TKI) targeting VEGFR -1, -2, and -3, and has recently received approval by the U.S. Food and Drug Administration for treatment of mCRC refractory to standard chemotherapy, anti-VEGF therapy, and anti-epidermal growth factor receptor (EGFR) therapy. AREAS COVERED: This article provides an overview of the pre-clinical data, pharmacokinetics, clinical efficacy, and safety profile of fruquintinib, as well as the management of clinical toxicities associated with fruquintinib. EXPERT OPINION: Fruquintinib is a valuable additional treatment option for patients with refractory mCRC. The pivotal role of vigilant toxicity management cannot be understated. While fruquintinib offers a convenient and overall, well-tolerated treatment option, ongoing research is essential to determine its efficacy in different patient subsets, evaluate it in combination with chemotherapy and immunotherapy, and determine its role in earlier lines of therapy.

INTRODUCTION: This real-world US-based claims study compared constipation-related symptoms and complications 6 months before and after prucalopride initiation in adults with chronic idiopathic constipation (CIC). METHODS: This observational, retrospective cohort analysis used the IBM MarketScan Commercial Claims and Encounters Database and the Medicare Supplemental Database (January 2015-June 2020). Prucalopride-treated patients (≥18 years old) who had ≥1 constipation-related International Classification of Diseases, Tenth Revision, Clinical Modification ( ICD-10-CM ) diagnosis code during the baseline or study period were included. The proportions of patients with constipation-related symptoms (abdominal pain, abdominal distension [gaseous], incomplete defecation, and nausea) and constipation-related complications (anal fissure and fistula, intestinal obstruction, rectal prolapse, hemorrhoids, perianal venous thrombosis, perianal/perirectal abscess, and rectal bleeding) were examined. Constipation-related symptoms and complications were identified using ICD-10-CM , ICD-10 - Procedure Coding System , or Current Procedural Terminology codes. Data were stratified by age (overall, 18-64 years, and ≥65 years). RESULTS: This study included 690 patients: The mean (SD) patient age was 48.0 (14.7) years, and 87.5% were women. The proportions of patients overall with constipation-related symptoms decreased 6 months after prucalopride initiation (abdominal pain [50.4% vs 33.3%, P < 0.001]; abdominal distension [gaseous] [23.9% vs 13.3%, P < 0.001]; and nausea [22.6% vs 17.7%, P < 0.01]; no improvements observed for incomplete defecation). Similarly, the proportions of patients overall with constipation-related complications decreased 6 months after prucalopride initiation (intestinal obstruction [4.9% vs 2.0%, P < 0.001]; hemorrhoids [10.7% vs 7.0%, P < 0.05]; and rectal bleeding [4.1% vs 1.7%, P < 0.05]). DISCUSSION: This study suggests that prucalopride may be associated with improved constipation-related symptoms and complications 6 months after treatment initiation.

OBJECTIVE: To evaluate the efficacy and safety of Ginkgolide Meglumine Injection (GMI) combined with Butylphthalide in the treatment of Acute Ischemic Stroke (AIS), and provide reference for rational clinical medication. METHODS: PubMed, Embase, Web of science, CNKI, Wanfang, VIP and other databases were searched for published studies on the treatment of AIS with GMI combined with Butylphthalide in both Chinese and English. The search period was from the establishment of the database to July 2023. The included studies that met the inclusion criteria were analyzed using RevMan 5.3 software for Meta-analysis. RESULTS: A total of 25 studies involving 2362 patients (experimental group = 1182, control group = 1180) were included. The results of meta-analysis showed that the overall effective rate of the experimental group was significantly higher than that of the control group [RR = 1.21, 95% CI (1.16, 1.26), P< 0.00001]. In addition, compared with the control group, the experimental group showed significant improvement in NIHSS score [SMD = -1.59, % CI (-2.00-1.18), P< 0.00001] and ADL score [SMD = 2.12, 95% CI (1.52, -2.72), P<0.00001], significant decrease in CRP [SMD = -2.24, 95% CI (-3.31, -1.18), P<0.0001] and TNF-α [SMD = -2.74, 95% CI (-4.45, -1.03), P< 0.005] levels, and improvement in plasma viscosity [SMD = -0.86, 95% CI (-1.07, -0.66), P< 0.00001]. However, the influence on homocysteine level remains inconclusive. Furthermore, there was no significant difference in the incidence of adverse reactions between the two groups [SMD = 0.95, 95% CI (0.71, 1.28), P> 0.05]. CONCLUSION: GMI combined with Butylphthalide shows good clinical application effects and good safety in the treatment of AIS. However, more large-sample, multicenter, randomized controlled are needed to confirm these findings.

INTRODUCTION: Pediatric prucalopride studies for treatment of gastrointestinal (GI) disorders have reported mixed results. We aimed to assess the safety and effectiveness of prucalopride in functional constipation (FC) with and without upper GI symptoms. METHODS: Retrospective data on patients with FC receiving combined prucalopride and conventional therapy was compared with those receiving conventional therapy alone within 12 months. Thirty patients on combined therapy and those on conventional therapy were each matched on the basis of age, gender, race, and presence of fecal soiling. Response (complete, partial, or no resolution) was compared. Similarly, response to concurrent functional upper GI symptoms (postprandial pain, bloating, weight loss, vomiting, early satiety, or nausea) and dysphagia, as well as adverse effects, were evaluated in the combined group. RESULTS: Mean age of 57 cases was 14.7 ± 4.9 years and 68% were female. Comorbidities included functional upper GI (UGI) symptoms (84%), dysphagia (12%), mood disorders (49%), and hypermobility spectrum disorder (37%). Unmatched cases reported 63% improvement to FC; response did not differ between the matched cohorts (70% versus 76.6%, p = 0.84). Cases showed a 56% improvement in functional UGI symptoms and 100% in dysphagia. Adverse effects were reported in 30%, abdominal cramps being most common. Four (7%) patients with a known mood disorder reported worsened mood, of which two endorsed suicidal ideation. CONCLUSION: Prucalopride efficaciously treated concurrent UGI symptoms and dysphagia in constipated pediatric patients and was overall well tolerated. Preexisting mood disorders seemed to worsen in a small subset of cases.

BACKGROUND: Fruquintinib has demonstrated significant improvement in overall survival (OS) among previously treated metastatic colorectal cancer (mCRC) patients. However, the utilization of fruquintinib has been constrained by various toxicities, such as hand-foot skin reaction (HFSR) and hypertension, particularly in elderly patients with reduced tolerance to the standard dosage. This study aims to investigate the efficacy and safety of fruquintinib dose-escalation strategy for elderly refractory mCRC patients. PATIENTS AND METHODS: This open-label, single-arm, phase II trial included patients aged 65 years or over with mCRC who had progressed after two or more lines of chemotherapy. Fruquintinib was administered for 21 consecutive days of a 28-day treatment cycle. The starting dose of fruquintinib was 3 mg/day and escalated to 4 mg/day in Week 2 and 5 mg/day in Week 3 if no significant drug-related toxicity was observed. The highest tolerated dose from Cycle 1 would be administered in Cycle 2 and all subsequent cycles. Before commencing treatment, all enrolled patients underwent a G8 questionnaire and comprehensive geriatric assessments. The primary endpoint of the study was progression-free survival (PFS). RESULTS: A total of 29 patients were enrolled and all started fruquintinib at 3 mg/day. Fifteen patients (51.7%) were subsequently escalated to 4 mg/day and 4 (13.8%) to 5 mg/day. Only four (13.8%) patients discontinued treatment due to adverse events (AEs). The median PFS was 3.8 months (95% CI, 2.7-4.9), and the median OS was 7.6 months (95% CI, 6.5-8.7). Treatment-related adverse events (TRAEs) were observed in all 29 patients (100%). The most frequently occurring (>10%) TRAEs greater than Grade 3 were HFSR (20.7%), hypertension (20.7%), and diarrhea (10.3%). CONCLUSION: Our study indicated that a dose of 4 mg/day was well tolerated by most elderly patients, suggesting that fruquintinib dose-escalation strategy during the first cycle could serve as a viable alternative to the standard 5 mg/day dosing.

This open-label, phase 1/1b study was conducted to evaluate the safety, tolerability, and pharmacokinetics (PK) of fruquintinib in United States (U.S.) patients to confirm the recommended phase 2 dose (RP2D) established in China. Patients with advanced solid tumors who had progressed on approved systemic therapy, were enrolled into 2 successive dose escalation cohorts, fruquintinib 3 mg (n = 7) or 5 mg (n = 7), orally, once daily (QD), 3 weeks on and 1 week off (3/1) with a 3 + 3 design followed by a dose expansion cohort at the RP2D 5 mg dose (n = 6). PK samples were collected on Days 1, 14, and 21 (Cycle 1). One of 6 dose-limiting toxicity (DLT)-evaluable patients in the 3 mg cohort had a DLT of grade 4 hypertension; there were no DLTs in the 5 mg cohort. The RP2D was confirmed to be 5 mg QD 3/1. All 20 patients experienced a treatment-emergent adverse event; grade ≥ 3 in 5 (71.4%; 3 mg dose) and 12 (92.3%; 5 mg dose) patients. Two patients had a confirmed partial response. After single and multiple doses, median peak plasma concentrations occurred at 2 h post-dose. Steady-state was achieved after 14 days of QD dosing with systemic exposure four-fold higher than that after a single dose. Fruquintinib was well tolerated, and the safety and PK profile at the 5 mg RP2D in U.S. patients with advanced solid tumors was consistent with dose-finding studies in China. Preliminary anticancer activity was observed. This study is registered at Clinicaltrials.gov NCT03251378.

Synthetic glucocorticoid administration has been reported to play a role in depression and cognitive decline. The present study investigated the 2-phenyl-3-(phenylselanyl)benzofuran (SeBZF1) effects against the depressive-like behavior, memory impairment, and neurochemical alterations caused by acute dexamethasone administration in female Swiss mice. A dexamethasone dose-response curve (0.07-0.5 mg/kg, subcutaneous route, s.c.) was initially performed to validate the depressive-like behavior induction, in which the 0.25 mg/kg dose was more effective. Two experimental sets were performed to test the SeBZF1 (5 and 50 mg/kg, intragastric route, i.g.) pharmacological effect in this animal model. The 1st set revealed that the SeBZF1 reverses the dexamethasone-induced depressive-like behavior in the tail suspension test and in the splash test. In the 2nd experimental set, the compound effects of reversing the depressive-like behavior in the forced swimming test and the memory deficit in the Y-maze test induced by acute treatment with dexamethasone were demonstrated. Furthermore, SeBZF1 reversed the increase in the monoamine oxidase (MAO) activity in the prefrontal cortex (isoforms A and B) and in the hypothalamus (isoform A) caused by dexamethasone. However, no changes were observed in hippocampal MAO activity. Furthermore, animals treated with dexamethasone and SeBZF1 demonstrated a partially lower acetylcholinesterase activity in the prefrontal cortex compared with the induced group. In summary, the present study demonstrated that SeBZF1 reverses depressive-like behavior and memory deficits caused by acute dexamethasone treatment in female Swiss mice. Possibly the compound exerts its antidepressant-like action by increasing the availability of monoamines, while its effects on memory are still partially understood.

BACKGROUND: Fruquintinib (anti-vascular endothelial growth factor 1/2/3) plus sintilimab (anti-programmed death-1) demonstrated enhanced anti-tumour effects versus monotherapy in a preclinical study. We investigated the combination in patients with advanced solid tumours, including metastatic colorectal cancer (mCRC). METHODS: In this phase 1b/2, open-label, multi-centre, multi-cohort dose-escalation and dose-expansion study, patients with advanced solid tumours (dose-escalation) or mCRC (one cohort in dose-expansion) received different doses of fruquintinib plus a fixed dose of sintilimab once every 4 weeks (Q4W) or 3 weeks (Q3W). Primary objectives were safety, tolerability, and the preliminary efficacy. This study is registered at ClinicalTrials.gov, NCT03903705. FINDINGS: By the data cut-off date (30th December 2021), 23 patients were enrolled in the dose-escalation and 37 patients in the mCRC cohort of the dose-expansion; 44 patients with mCRC who received sintilimab Q3W were pooled for analysis. One dose-limiting toxicity event (grade 3 troponin T increased) occurred during the dose escalation. Grade ≥3 treatment-related adverse events occurred in 43.5% and 47.7% of patients in the dose-escalation phase and pooled mCRC analysis, respectively. Among patients treated with the recommended phase 2 dose (fruquintinib 5 mg once daily, 2 weeks on/1 week off, plus sintilimab 200 mg Q3W) in pooled mCRC analysis, the objective response rate was 23.8% (95% CI 8.2-47.2), median progression-free survival was 6.9 months (95% CI 5.4-8.3), and overall survival was 14.8 months (95% CI 8.8-not reached); in patients with mismatch repair-proficient mCRC, these were 20.0% (95% CI 4.3-48.1), 6.9 months (95% CI 4.8-10.1), and 20.0 months (95% CI 8.1-not reached), respectively. INTERPRETATION: Fruquintinib plus sintilimab was well tolerated in patients with advanced solid tumours and showed promising efficacy in mCRC.

BACKGROUND: Current evidence for the efficacy of pharmacological treatment in improving cognitive function is absent. Recent studies have reported that 3-n-butylphthalide (NBP) has a positive effect on improving cognitive impairment; however, its clinical efficacy and safety is unclear. Therefore, we conducted a meta-analysis to assess its efficacy and safety for cognitive impairment. METHODS: We systematically searched the PubMed, EMBASE, Cochrane Library, Web of Science, and Scopus databases, and two reviewers independently screened and extracted the data from included studies. We synthesized the data using the Review Manager Software version 5.3. RESULTS: We included six randomized clinical trials (RCTs), encompassing 851 patients with cognitive impairment. The results showed that NBP improved cognitive impairment. Specifically, the clinical efficacy was better than that in the control group, with better performance in improving the Mini-Mental State Examination and the Montreal Cognitive Assessment scores, while decreasing the Alzheimer's Disease Assessment Scale-Cognitive subscale and the Clinician's Interview-Based Impression of Change plus caregiver input scores. There was no significant difference in the incidence of adverse events between both groups. CONCLUSION: The NBP is effective and safe in improving cognitive impairment; however, more high-quality RCTs are needed to confirm these findings.

BACKGROUND: As one of the leading causes of morbidity and mortality, stroke and its recurrence has attracted more and more attention. Dl-3-n-butylphthalidle(NBP) has been widely used for treating acute ischemic stroke in China and shows a great clinical effect. NBP plays a role in different pathophysiological processes in the treatment of ischemic stroke, including antioxidants, anti-inflammatory, anti-apoptotic, anti-thrombosis, and mitochondrial protection. Many randomized, double-blind, placebo-controlled, multicenter clinical trials suggest that NBP is a safe and effective treatment for ischemic stroke. To sum up, the current research is mainly focused on the short-term treatment of stroke patients with RCT (randomized controlled trial). Therefore, we designed this study to confirm the role of butylphthalide in secondary stroke prevention in the real world. METHODS: This study will be a multicenter, prospective real-world trial. We would recruit 8000 patients with ischemic stroke from 78 public hospitals in China. All participants will be allocated to one of two parallel treatment groups according to their own wills: (1) butylphthalide group: 0.2 g of butylphthalide capsules three times daily plus routine treatment (aspirin 50-300 mg/d, clopidogrel 75 mg/d, etc.); (2) control group: routine treatment (aspirin 50-300 mg/d, clopidogrel 75 mg/d, etc.). Treatment duration is 90 consecutive days or more. The primary outcome is recurrence rate of stroke within 1 month, 3 months, 6 months and 1 year in butylphthalide group and control group. The secondary outcomes included NIHSS score, the mRS score, other clinical cardiovascular events within one year (sudden death / myocardial infarction / arrhythmia / heart failure, etc.), and adverse events of patients in groups. NIHSS will be captured in the first month after discharge, and the others will be captured at the same time points as the primary end point. DISCUSSION: This trial will be exploring the efficacy and safety of butylphthalide in secondary prevention of ischemic stroke to expand the scope of application of butylphthalide soft capsules and provide new ideas for enriching the secondary prevention of stroke.

Polybrominated dibenzo-p-dioxins and dibenzofurans (PBDD/DFs) are byproducts of brominated flame retardants and can cause adverse health effects. Although exposure to polychlorinated (PC) DD/DFs induces toxic effects, including liver injury and neurobehavioral disorder, little is known about toxicities associated with PBDD/DF exposure. Thus, we examined effects of perinatal exposure to brominated congener on the infant mouse. Gene expression in several organs, such as the liver and brain, was analyzed in mouse offspring born to dams administered 2,3,7,8-tetrabromodibenzofuran (TBDF; 9 or 45 µg/kg body weight) or 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD; 3 µg/kg body weight) on gestational day 12.5. An increase in liver size was observed in TBDF- or TCDD-exposed offspring in infancy. Gene microarray analysis revealed that 163 and 36 genes were markedly upregulated and downregulated, respectively, in the liver of TBDF-exposed mice compared with those in vehicle-treated mice on postnatal day (PND) 5. Significant increases in Cyp1a1, Cyp1a2, Fmo3, and Pnliprp1 and decreases in Tff3, Ocstamp, Kcnk16, and Lgals2 mRNA levels in TBDF-exposed offspring on PNDs 5 and 12 were confirmed by quantitative PCR. In particular, a significant reduction in Tff3 mRNA in the liver, but not in the brain, small intestine, colon, and kidney, was observed in offspring perinatally exposed to TBDF or TCDD. Ultrasonic calls of TBDF- or TCDD-exposed offspring on PNDs 3-5 were impaired. Taken together, perinatal exposure to polyhalogenated dioxin/furan congeners disrupts gene expression patterns in the liver and ultrasonic calling during infancy. These results suggest that liver injury may contribute to neurobehavioral disorder.

BACKGROUND: Stroke can cause physical and mental problems. This study examined how the sequential therapy of N-butylphthalide (NBP) could effectively improve physical movement, life activities, and psychological disorders in stroke patients. METHODS: This double-blind, randomized controlled trial included middle-aged or elderly patients with acute ischemic stroke that had commenced within 48âhours before enrolment in the study. The experimental group was administered 100âmL NBP injections twice a day in the first 14âdays, and a sequential 200âmg NBP soft capsule 3 times a day for the next 76âdays. The control group was administered 100âmL NBP placebo injections twice a day in the first 14âdays and 200âmg sequential NBP placebo soft capsule 3 times a day for the next 76âdays. Primary outcomes were the National Institutes of Health Stroke Scale, the Barthel Index of activities of daily living, and Modified Rankin Scale which were evaluated at day 0, day 14, and month 1 or at day 14, month 3, and month 6. Secondary outcomes included the Hamilton Anxiety Scale and the Hamilton Depression Scale, all were evaluated on day 0, month 3, and month 6. Moreover, the adverse reaction of NBP or other serious adverse events were evaluated at each time. RESULTS: Our therapy significantly increased the Barthel Index of activities of daily living scores, decreased the National Institutes of Health Stroke Scale and Modified Rankin Scale scores, and the incidence of the Hamilton Anxiety Scale and the Hamilton Depression Scale of ischemic stroke patients (Pâ<â.05). CONCLUSION: Our results indicated that 90 days' sequential therapy with NBP as an additional therapy in the treatment of ischemic stroke can better improve patients' psychological and behavioral functions without significant side effects.

This study examined the safety, tolerability, and pharmacokinetics (PK) of napabucasin in healthy Asian and non-Asian participants and investigated the potential for QT/QTc interval prolongation. This five-part (A-E) study proceeded in a stepwise manner, unless stopping criteria were met. Parts A-D were randomized, double-blind, placebo-controlled, and included healthy Asian male and female and non-Asian male participants. PK parameters were measured following single-dose napabucasin (80-1200 mg) in the fasted or fed state (Part D). Potential QT/QTc interval prolongation was assessed using digital 12-lead electrocardiogram (Parts B and C). Part E was open-label, and examined the PK of single-dose napabucasin (240-720 mg) in healthy non-Asian males. Safety and tolerability were measured in Parts A-E. Changes from baseline in the Fridericia-corrected QT interval (ΔQTcF) and other electrocardiogram parameters were analyzed using a linear mixed-effects model. Napabucasin was well-tolerated across the study (n = 70), and no serious adverse events or significant safety issues were reported when administered with or without food. The most frequent treatment-emergent adverse events were diarrhea and abdominal pain, and these were mild in severity. No prolongation of the QTcF interval was reported following single-dose napabucasin (240-1200 mg) and changes in other cardiac parameters were negligible. The PK profile of napabucasin was consistent with earlier studies. Single-dose napabucasin was tolerated in healthy male and female participants, and no significant safety (including no QTcF prolongation) or tolerability issues were identified, irrespective of food intake. Clinical studies of napabucasin in advanced cancers are ongoing.
