BACKGROUND: Migraine is a disabling primary headache disorder often associated with triggers. Diet-related triggers are a common cause of migraine and certain diets have been reported to decrease the frequency of migraine attacks if dietary triggers or patterns are adjusted. OBJECTIVE: The systematic literature review was conducted to qualitatively summarize evidence from the published literature regarding the role of diet patterns, diet-related triggers, and diet interventions in people with migraine. METHODS: A literature search was carried out on diet patterns, diet-related triggers, and diet interventions used to treat and/or prevent migraine attacks, using an a priori protocol. MEDLINE and EMBASE databases were searched to identify studies assessing the effect of diet, food, and nutrition in people with migraine aged ≥18 years. Only primary literature sources (randomized controlled trials or observational studies) were included and searches were conducted from January 2000 to March 2019. The NICE checklist was used to assess the quality of the included studies of randomized controlled trials and the Downs and Black checklist was used for the assessment of observational studies. RESULTS: A total of 43 studies were included in this review, of which 11 assessed diet patterns, 12 assessed diet interventions, and 20 assessed diet-related triggers. The overall quality of evidence was low, as most of the (68%) studies assessing diet patterns and diet-related triggers were cross-sectional studies or patient surveys. The studies regarding diet interventions assessed a variety of diets, such as ketogenic diet, elimination diets, and low-fat diets. Alcohol and caffeine uses were the most common diet patterns and diet-related triggers associated with increased frequency of migraine attacks. Most of the diet interventions, such as low-fat and elimination diets, were related to a decrease in the frequency of migraine attacks. CONCLUSIONS: There is limited high-quality randomized controlled trial data on diet patterns or diet-related triggers. A few small randomized controlled trials have assessed diet interventions in preventing migraine attacks without strong results. Although many patients already reported avoiding personal diet-related triggers in their migraine management, high-quality research is needed to confirm the effect of diet in people with migraine.

BACKGROUND Long-term glycemic control reduces retinopathy risk, but transient worsening can occur with glucose control intensification. Glucagon-like peptide 1 receptor agonists (GLP-1RA) lower glucose, but the long-term impact on retinopathy is unknown. GLP-1RA cardiovascular outcome trials (CVOTs) provide long-term follow-up, allowing examination of retinopathy outcomes. PURPOSE To examine the associations between retinopathy, HbA1c, systolic blood pressure (SBP), and weight in GLP-1RA CVOTs. DATA SOURCES Systematic review identified six placebo-controlled GLP-1RA CVOTs reporting prespecified retinopathy outcomes. STUDY SELECTION Published trial reports were used as the primary data sources. DATA EXTRACTION HbA1c, SBP, and weight data throughout follow-up by treatment group were extracted. DATA SYNTHESIS Random-effects model meta-analysis showed no association between GLP-1RA treatment and retinopathy (odds ratio [OR] 1.10; 95% CI 0.93, 1.30), with high heterogeneity between studies (I2 = 52.2%; Q statistic P = 0.063). Univariate meta-regression showed an association between retinopathy and average HbA1c reduction during the overall follow-up (slope = 0.77, P = 0.007), but no relationship for SBP or weight. Sensitivity analyses for HbA1c showed a relationship at 3 months (P = 0.006) and 1 year (P = 0.002). A 0.1% (1.09 mmol/mol) increase in HbA1c reduction was associated with 6%, 14%, or 8% increased Ln(OR) for retinopathy at the 3-month, 1-year, and overall follow-up, respectively. LIMITATIONS CVOTs were not powered to assess retinopathy outcomes and differed in retinopathy-related criteria and methodology. The median follow-up of 3.4 years is short compared with the onset of retinopathy. CONCLUSIONS HbA1c reduction was significantly associated with increased retinopathy risk in meta-regression for GLP-1RA CVOTs. The magnitude of HbA1c reduction was correlated with retinopathy risk in people with diabetes and additional cardiovascular risk factors, but the long-term impact of improved glycemic control on retinopathy was unmeasured in these studies. Retinopathy status should be assessed when intensifying glucose-lowering therapy.

The primary objective of this study was to determine the response rates of the gemcitabine and cisplatin combination in unresectable gall bladder cancer patients. The secondary objectives were to evaluate the toxicity, time to progressive disease, and overall survival. Chemonaïve patients with histologically proven, unresectable bidimensionally measurable gall bladder cancer were enrolled into this study. All patients were required to have a Zubrod's performance status <or=2, no prior radiotherapy, and adequate major organ function. Patients received gemcitabine (1000 mg x m(-2) intravenously over 30-60 min) on days 1 and 8, and cisplatin (70 mg x m(-2) intravenously over 2 h) on day 1, every 21 days. Response assessment was done by a CT scan after every other cycle of chemotherapy. In all, 30 patients were eligible for efficacy and toxicity analysis. There were four (13.3%) complete responders, seven (23.3%) partial responders, and seven (23.3%) with stable disease, with four (13.2%) patients showing disease progression. The median time to progression was 18 weeks (95% confidence interval (CI) 14-24 weeks), and the median duration of response was 13.5 weeks (range 5.5-104 weeks). The median overall survival was 20 weeks (95% CI 14-31 weeks), with 1-year survival rate of 18.6%. WHO grade 3 or 4 anaemia was seen in seven (23.3%) and four (13.3%) patients, respectively. Five (16.6%) patients each experienced grade 3 or 4 neutropenia, and grade 3 or 4 thrombocytopenia was seen in three (10%) and two (6.6%) patients, respectively. The present study shows that gemcitabine/cisplatin combination is well tolerated and active in advanced unresectable gall bladder cancer.

The biological activities of several derivatives of human proinsulin (HPI) containing peptide bond cleavages or peptide deletions in the connecting peptide region were examined in vivo in rats and in several in vitro systems. The two derivatives which were tested in vivo, split (32-33)HPI and des-(64,65)HPI, both demonstrated greater potency in lowering blood glucose than did intact HPI. The receptor binding affinities of split (65-66)HPI, des-(57-65)HPI, des-(64,65)HPI, des-(33-56)HPI, des-(31,32)HPI, split (32-33)HPI, and split (56-57)HPI were examined in cultured IM-9 lymphocytes, freshly isolated rat adipocytes, and purified rat liver membranes and were compared to the binding of intact HPI and insulin. In these systems, HPI averaged approximately 1% of the activity of insulin. Modification of proinsulin in the connecting peptide region near the A-chain of insulin to form split (65-66)HPI, des-(57-65)HPI, des-(64,65)HPI, or des-(33-56)HPI resulted in an increase in affinity for receptor binding ranging from 11 to 27-fold over that of intact HPI. In contrast, modifications near the B-chain of insulin to form either des-(31,32)HPI or split (32-33)HPI resulted in roughly a 5-fold increase in affinity, whereas a cleavage within the connecting peptide to form split (56-57)HPI showed only a 2-fold increase in affinity as compared to intact HPI. The biological potencies of these materials were examined in isolated rat adipocytes. At high concentrations (10(-7) M), each derivative produced the same maximal response. At lower concentrations, differences in the relative potencies paralleled the differences in receptor binding affinity previously noted.

Obstructive sleep apnea (OSA) is strongly associated with obesity. While the relationship between weight reduction and apnea-hypopnea index improvement has been documented, to our knowledge, it has not been quantified adequately. Therefore, this study aimed to quantify the relationship between weight reduction and AHI change. METHODS: A systematic literature search was performed using meta-analyses (PRISMA) guidelines for studies reporting AHI and weight loss in people with obesity/overweight and OSA between 2000 and 2023. A linear and quadratic model (weighted by treatment arm sample size) predicted percent change from baseline AHI against mean percent change from baseline weight. The quadratic term was statistically significant (P < 0.05), so the quadratic model (with 95 % prediction interval) was used. RESULTS: The literature search identified 27 studies/32 treatment arms: 15 using bariatric surgery and lifestyle intervention each and 2 using pharmacological interventions. Included studies were ≥3 months with weight intervention and participants had AHI ≥15/h. Weight reduction in people with OSA and obesity was associated with improvements in the severity of OSA. BMI reduction of 20 % was associated with AHI reduction of 57 %, while further weight reduction beyond 20 % in BMI was associated with a smaller effect on AHI. As the prediction intervals are relatively wide, a precise relationship could not be conclusively established. CONCLUSION: The degree of AHI index improvement was associated with the magnitude of weight reduction. The model suggests that with progress in weight reduction beyond 20 %, the incremental decrease in BMI appeared to translate to a smaller additional effect on AHI.

Glucagon-like peptide-1 (GLP-1)-based therapy improves glycaemic control through multiple mechanisms, with a low risk of hypoglycaemia and the additional benefit of clinically relevant weight loss. Since Starling and Bayliss first proposed the existence of intestinal secretions that stimulate the pancreas, tremendous progress has been made in the area of incretins. As a number of GLP-1 receptor agonists (GLP-1 RAs) continue to become available, physicians will soon face the challenge of selecting the right option customized to their patient's needs. The following discussion, derived from an extensive literature search using the PubMed database, applying the terms incretin, GLP-1, exenatide, liraglutide, albiglutide, dulaglutide, lixisenatide, semaglutide, and taspoglutide, provides a comprehensive review of existing and upcoming molecules in the GLP-1 RA class in terms of their structure, pharmacological profiles, efficacy, safety, and convenience. Search Methodology: A literature search was conducted using the PubMed database, applying the terms incretin, GLP-1, exenatide, liraglutide, albiglutide, dulaglutide, lixisenatide, semaglutide, and taspoglutide. Relevant articles were those that discussed structural, pharmacokinetic and pharmacodynamic differences, classification, long-acting and short-acting GLP-1 RAs, phase 3 trials, and expert opinions. Additional targeted searches were conducted on diabetes treatment guidelines and reviews on safety, as well as the American Diabetes Association/European Society for Study of Diabetes (ADA/EASD) statement on pancreatic safety.

BACKGROUND: Understanding the trend of global antifungal agent consumption could assist with identification of global healthcare policy inadequacies and promote accessibility and availability of antifungal agents. METHODS: Using pharmaceutical sales data from the IQVIA-multinational integrated data analysis system database, we assessed use of systemic antifungal agents in humans in 27 middle- and 38 high-income countries from 2008 through 2018. RESULTS: Consumption of systemic antifungal agents increased from 0.50 (in 2008) to 0.92 defined daily dose (DDD)/1000 inhabitants/day (in 2018), with a compound annual growth rate of 6.2%. High-income countries remain major consumers of antifungal agents with large variance in quantities consumed, with a gradual decline in consumption in recent years. Consumption in middle-income countries increased. Itraconazole (0.32 DDD/1000 inhabitants/day), terbinafine (0.30 DDD/1000 inhabitants/day), and fluconazole (0.23 DDD/1000 inhabitants/day) were the most commonly used antifungal agents in middle- and high-income countries in 2018. Following incorporation into the World Health Organization Essential Medicines List, itraconazole consumption in middle-income countries surged. Consumption of ketoconazole slowly declined, with 5.04% annual decrease, probably due to labelling changes in 2013 to reflect hepatotoxicity concerns. The use of polyenes (0.004 DDD/1000 inhabitants/day) and echinocandins (0.003 DDD/1000 inhabitants/day) were lowest among all the antifungal drug classes. CONCLUSION: Global consumption of triazoles and terbinafine has gradually increased in middle- and high-income countries. Life-saving antifungal agents, including echinocandins and polyenes, are available only parenterally and may be underutilized, mainly in middle-income countries. Future research on country-specific epidemiology is warranted to guide health policy coordination to ensure equitable access to appropriate use of antifungal agents.

BACKGROUND: Cisplatin-based therapy is standard in patients with advanced urothelial carcinoma but a large proportion are ineligible due to renal impairment. The safety and activity of a dose-dense carboplatin-based regimen in this patient population were explored. METHODS: Patients with advanced urothelial carcinoma who were ineligible for cisplatin were eligible based on at least 1 of the following: 1) serum creatinine >1.5 mg/dL; 2) creatinine clearance of >30 mL/min/1.73 m(2) and <60 mL/min/1.73 m(2); and/or 3) prior nephrectomy. Patients received treatment with doxorubicin plus gemcitabine every other week x 5 cycles followed by paclitaxel plus carboplatin weekly x 12 cycles. RESULTS: Twenty-five patients were treated. Myelosuppression was the major toxicity, with 28% of patients experiencing grade 3-4 neutropenia; there were only 2 (8%) episodes of febrile neutropenia. Grade > or = 3 nonhematologic toxicities were infrequent with the exception of grade > or = 3 thrombotic episodes in 4 (16%) patients. There were 5 complete responses and 9 partial responses for an overall response rate of 56% (95% confidence interval [CI]: 35%-76%). The median survival was 15 months (95% CI: 11-30). At a median follow-up for survivors of 45 months, 7 (28%) patients are disease-free. CONCLUSIONS: Dose-dense sequential chemotherapy is tolerable and active in patients with urothelial carcinoma and renal impairment. Prolonged disease-free survival is achievable in a subset of patients with primary unresectable disease or lymph-node only metastases treated with carboplatin-based therapy +/- surgical consolidation. Randomized trials are needed to define the optimal regimen in patients with advanced urothelial carcinoma and renal impairment.

In the present multicentre, open-label, prospective, phase III study, we evaluated the real-world effectiveness and ease of use of nasal glucagon (NG) in the treatment of moderate/severe hypoglycaemic events (HEs) in adults with type 1 diabetes (T1D). Patients and caregivers were taught how to use NG (3 mg) to treat moderate/severe HEs, record the time taken to awaken or return to normal status, and measure blood glucose (BG) levels over time. Questionnaires were used to collect information about adverse events and ease of use of NG. In the efficacy analysis population, 69 patients experienced 157 HEs. In 95.7% patients, HEs resolved within 30 minutes of NG administration. In all the 12 severe HEs, patients awakened or returned to normal status within 15 minutes of NG administration without additional external medical help. Most caregivers reported that NG was easy to use. Most adverse events were local and of low to moderate severity. In this study, a single, 3-mg dose of NG demonstrated real-life effectiveness in treating moderate and severe HEs in adults with T1D. NG was well tolerated and easy to use.

The signed informed consent form provides documentary evidence that the patient has given informed consent to participate in a clinical trial and that the patient has been given the requisite information. However, this document must not only provide the necessary information, it must also be provided in a way that can be understood by the patient. Non conclusive information suggests that research participants frequently may not understand the information presented during the informed consent procedure. Comprehension requires that the patient be able to understand the information presented and have the time and opportunity to read, evaluate and consider the information presented.A shortened Informed Consent Form, with information that a reasonable person would want to understand along with specific information that the person wants in particular would be a good option to improve understanding or comprehensibility. Additional informational meetings with a qualified person like a counselor could help in comprehension. Questionnaires designed to test comprehension of patient, peer review, patient writing the salient features could help evaluate the comprehensibility of the Informed Consent Form.

The aim of the present paper was to compare the efficacy and safety of duloxetine with paroxetine in the acute treatment of major depressive disorder (MDD). In a randomized, double-blind trial of 8 weeks active treatment, patients with non-psychotic MDD were randomized to duloxetine 60 mg (n = 238) or paroxetine 20 mg (n = 240) once daily. Efficacy was primarily measured on change in the 17-item Hamilton Rating Scale for Depression (HAMD(17)) using a non-inferiority test with a margin of 2.2. Secondary efficacy measures included the HAMD(17) subscales, Hamilton Rating Scale for Anxiety, Clinical Global Impressions-Severity, Patient Global Impressions-Improvement, Somatic Symptoms Inventory and Visual Analog Scales (VAS) for pain. Safety measures included treatment-emergent adverse events (TEAE), vital signs, weight, laboratory analyses and electrocardiograms. Non-inferiority of duloxetine to paroxetine was demonstrated because the upper bound of the confidence interval for mean difference in HAMD(17) change (0.71) was less than the non-inferiority margin. Secondary efficacy end-points did not differ significantly between treatments with the exception of VAS back pain, where the pooled mean was lower in the duloxetine group (17.1) compared with the paroxetine group (20.3, P = 0.048). No significant differences were observed in the number of early discontinuations and overall TEAE. However, significantly greater proportions of patients in the duloxetine group experienced nausea and palpitations. No clinically relevant changes in laboratory values, vital signs, weight or electrocardiograms were observed with either treatment. The present study verifies the utility of duloxetine as an efficacious and safe treatment for both emotional and physical symptoms of MDD in this predominantly Asian patient sample.

OBJECTIVE: This meta-analysis examined suicide-related events in the acute phases of double-blind, placebo-controlled atomoxetine trials in pediatric and adult patients with attention-deficit/hyperactivity disorder (ADHD). METHODS: A total of 3883 pediatric and 3365 adult patients were included. Potential events were identified from the adverse events database using a text-string search. Mantel-Haenszel risk ratios (MHRR) were calculated for potential suicide-related events categorized according to United States Food and Drug Administration defined codes. RESULTS: In this data set, no completed suicides were reported in the pediatric or adult populations. One pediatric (attempted suicide) (and no adult patient events) was categorized as suicidal behavior in the atomoxetine group. The frequency of combined suicidal behavior or ideation with atomoxetine treatment was 0.37% in pediatric patients (vs. 0.07% with placebo) and 0.11% in adults (vs. 0.12% with placebo) and the risk compared with placebo was not statistically significant (MHRR=1.57; p=0.42 and MHRR=0.96; p=0.96, respectively). In pediatric patients, suicidal ideation only was reported more frequently compared with placebo (MHRR=1.63; p=0.41). CONCLUSIONS: Overall in this data set, no completed suicides and 1 pediatric patient suicidal behavior event were reported in atomoxetine-treated pediatric and adult patients. Suicidal ideation was uncommon among atomoxetine-treated pediatric and adult patients, although it was reported more frequently in atomoxetine-treated pediatric patients compared with placebo; the reporting rate difference was not statistically significant. The MHRR of suicidal ideation was consistent with a previous meta-analysis of similar design. There was no evidence of increased risk for suicidal behavior in atomoxetine-treated pediatric or adult patients. CLINICAL TRIAL REGISTRATION INFORMATION: http://www.clinicaltrials.gov . The data reported are from an analysis of 23 pediatric and 9 adult clinical trials completed between 1998 and 2011. Ten pediatric (Studies HFBD, HFBK, LYAC, LYAS, LYAT, LYAW, LYAX, LYBG, LYBI, and LYBP) and two adult trials (Studies LYAA and LYAO) were conducted before the requirement to post trials at initiation (ongoing as of July 1, 2005) and, therefore, do not have a registration number. The registration numbers for the 13 pediatric trials meeting this requirement are: NCT00191698 (LYBX), NCT00486122 (LYCC), NCT00386581 (LYCZ), NCT00485459 (S010), NCT00191542 (LY15), NCT00191295 (LYBC), NCT00191906 (LYCK), NCT00192023 (LYCY), NCT00191945 (LYDM), NCT00546910 (LYDV), NCT00406354 (LYDW), NCT00380692 (S017), and NCT00607919 (LYEB). For the seven adult trials, the registration numbers are: NCT00190931 (LYBV), NCT00190957 (LYBY), NCT00190736 (LYCU), NCT00190775 (LYCW), NCT00190879 (LYDQ), NCT00510276 (LYDZ), and NCT00962104 (LYEE).

OBJECTIVE: This multicenter, open-label study was designed to evaluate real-world effectiveness and ease of use of nasal glucagon (NG) in treating moderate or severe hypoglycemic events in children and adolescents with type 1 diabetes (T1D). METHODS: Caregivers were trained to administer NG (3 mg) to the child/adolescent with T1D during spontaneous, symptomatic moderate or severe hypoglycemic events, observe treatment response (defined as awakening or returning to normal status within 30 minutes), and measure blood glucose (BG) levels every 15 minutes. Data regarding adverse events and ease of use were solicited using questionnaires. RESULTS: The analysis population included 14 patients who experienced 33 moderate hypoglycemic events with neuroglycopenic symptoms and BG level ≤70 mg/dL. Patients returned to normal status within 30 minutes of NG administration in all 33 events. Mean BG levels increased from 55.5 mg/dL (range 42-70 mg/dL) at baseline to 113.7 mg/dL (range 79-173 mg/dL) within 15 minutes of NG administration. In most hypoglycemic events (93.9%), caregivers reported that NG administration was easy or very easy; they could administer NG within 30 seconds in 60.6% of events. There were no serious adverse events. CONCLUSIONS: A single 3-mg dose of NG was effective in treating moderate, symptomatic, hypoglycemic events in children and adolescents with T1D in a real-world setting. It was easy-to-use and reasonably well tolerated. NG shows promise as an effective, needle-free, and user-friendly alternative to injectable glucagon.

Application of computational methods to understanding and predicting properties of analogues for drug discovery has enjoyed a long history of success. However, the drug development space (post-candidate selection) is currently experiencing a rapid growth in this arena. Due to the revolution in computing hardware development and improved computational techniques, quantum chemical (QC) calculations have become an essential tool in this space, allowing results from complex calculations to inform chemical development efforts. As a result, numerous pharmaceutical companies are employing QC as part of their drug development workflow. Calculations cover the range of transition state calculations, reaction path determination, and potential energy surface scans, among others. The impact of this rapid growth is realized by providing an in-depth understanding of chemical processes and predictive insight into the outcome of potential process routes and conditions. This review surveys the state of the art in these drug development applications in the pharmaceutical industry. Statistics of computational methods, software, and other metrics for publications in the last 14 years (2005–2019) are presented. Predictive applications of quantum chemistry for influencing experiments in reaction optimization and catalyst design are described. Important gaps in hardware and software capabilities that need to be addressed in order for quantum chemistry to become a more practical and impactful tool in pharmaceutical drug development are discussed. Perspectives for the future direction of application of QC to pharmaceutical drug development are proposed.

BACKGROUND: Rheumatoid arthritis (RA) is associated with significantly diminished health-related quality of life. Patient-reported outcomes (PROs) are considered important in RA; however, some symptoms such as morning joint stiffness (MJS) and fatigue that are considered important by patients are not captured by the American College of Rheumatology "core set" measures for RA trials. The US Food and Drug Administration has endorsed electronic capture of clinical trial data including PROs, and electronic PRO (ePRO) systems may lead to more accurate and complete data capture, improved compliance, and patient acceptance compared with paper-based methods. Our objective was to assess the implementation of ePRO measures of Duration and Severity of MJS, Severity of Worst Tiredness, and Severity of Worst Joint Pain in baricitinib RA-BEAM and RA-BUILD phase 3 randomized clinical trials (RCTs). METHODS: A daily electronic diary (handheld device; Invivodata®, Inc.) was utilized to capture PRO data in the RCTs. Three "reporting window" options were incorporated to accommodate differences in patients' routine daily schedules, and alarms were programmed for each reporting window. Duration of MJS was recorded in "hours and minutes," and Severity of MJS, Worst Tiredness, and Worst Joint Pain were captured on a 0 to 10 rating scale, with a higher score indicating more severe symptoms. The patients and site staff were trained to use the daily electronic diary. RESULTS: Patients with moderately to severely active RA used the daily electronic diary in the RA-BEAM study (N = 1305) and RA-BUILD study (N = 684). The average compliance, calculated as total days completed by patients compared with total days expected to complete the diary, through Week 12 was high (RA-BEAM 94% patients; RA-BUILD 93% patients), potentially attributable to appropriate training, clarity of instructions, simple user interface, and electronic device design. Identified process challenges included non-timely issuance of the device, low battery, inadequate training of patients before data collection, inappropriate diary set-up, and first response entry 1 day after the baseline visit. CONCLUSIONS: High compliance rates support the use of the daily electronic PRO diary in large RCTs. Despite the anticipated issues, the daily electronic diary is expected to reduce recall bias and improve the quality of PRO data collection. TRIAL REGISTRATION: RA-BEAM ( NCT01710358 ) and RA-BUILD ( NCT01721057 ).

This study examined the pathological complete response (pCR) rate and safety of sequential gemcitabine-based combinations in breast cancer. We also examined gene expression profiles from tumour biopsies to identify biomarkers predictive of response. Indian women with large or locally advanced breast cancer received 4 cycles of gemcitabine 1200 mg m(-2) plus doxorubicin 60 mg m(-2) (Gem+Dox), then 4 cycles of gemcitabine 1000 mg m(-2) plus cisplatin 70 mg m(-2) (Gem+Cis), and surgery. Three alternate dosing sequences were used during cycle 1 to examine dynamic changes in molecular profiles. Of 65 women treated, 13 (24.5% of 53 patients with surgery) had a pCR and 22 (33.8%) had a complete clinical response. Patients administered Gem d1, 8 and Dox d2 in cycle 1 (20 of 65) reported more toxicities, with G3/4 neutropenic infection/febrile neutropenia (7 of 20) as the most common cycle-1 event. Four drug-related deaths occurred. In 46 of 65 patients, 10-fold cross validated supervised analyses identified gene expression patterns that predicted with >or=73% accuracy (1) clinical complete response after eight cycles, (2) overall clinical complete response, and (3) pCR. This regimen shows strong activity. Patients receiving Gem d1, 8 and Dox d2 experienced unacceptable toxicity, whereas patients on other sequences had manageable safety profiles. Gene expression patterns may predict benefit from gemcitabine-containing neoadjuvant therapy.

BACKGROUND: Efficacy of galcanezumab in chronic migraine has been demonstrated in a pivotal Phase 3 study. Here, we assess efficacy in patients who have failed ≥2 and ≥1 prior migraine preventives for efficacy and/or safety reasons, and in those who never failed. STUDY DESIGN/METHODS: REGAIN (NCT02614261) was a Phase 3, randomized, double-blind, placebo-controlled study in patients with chronic migraine. Patients were randomized 2:1:1 to receive placebo, galcanezumab 120 mg/240 mg once monthly during a double-blind treatment period lasting three months. Subgroup analyses were conducted among patients who failed ≥2 and ≥1 prior preventives and who never failed previously. Outcomes assessed were change from baseline in number of monthly migraine headache days, proportion of patients with ≥50% and ≥75% response (reduction in monthly migraine headache days), change in number of monthly migraine headache days with acute medication use and change in patient functioning per Migraine-Specific Quality of Life Questionnaire Role Function Restrictive (MSQ RF-R) domain score. RESULTS: < 0.01) in overall reduction (Months 1-3) from baseline in the number of monthly migraine headache days in patients with prior failures (LS mean change [SE]: ≥2 prior failures: galcanezumab 120 mg: -5.35 (0.71); galcanezumab 240 mg: -2.77 (0.66); placebo: -1.01 (0.54); ≥1 prior failures: galcanezumab 120 mg: -5.53 (0.60), galcanezumab 240 mg: -3.53 (0.59); placebo: -2.02 (0.49). Similarly, significant results were seen with galcanezumab versus placebo for ≥50% and ≥75% response rates, reductions in acute medication use and improvements in MSQ RF-R domain score. In the subgroup with no prior preventive failures, results were statistically significant for the 240 mg galcanezumab group versus placebo on all outcome measures, and for the 120 mg group on the reduction in migraine headache days with acute medication use. There was also a higher placebo response observed in the patients with no prior preventive failures. CONCLUSION: Galcanezumab is consistently efficacious versus placebo in reducing monthly migraine headache days and several other key outcomes in patients with chronic migraine who have failed ≥2 or ≥1 preventives previously. In the subgroup with no prior failures, greater numerical differences were seen with galcanezumab, but statistical separation from placebo varied by dose and outcome. CLINICALTRIALS.GOV IDENTIFIER NUMBER: NCT02614261.

BACKGROUND AND PURPOSE: The efficacy of galcanezumab, a monoclonal antibody for migraine prevention, has been demonstrated in two pivotal trials in patients with episodic migraine. METHODS: EVOLVE-1 and EVOLVE-2 were identical phase 3, randomized, double-blind, placebo-controlled studies in patients with episodic migraine. Mean migraine headache days per month at baseline was 9. Patients were randomized 2:1:1 to monthly injections of placebo, galcanezumab 120 mg/240 mg during the 6-month double-blind treatment period. Key efficacy outcomes were assessed in subgroups amongst patients for whom, previously, for efficacy and/or safety/tolerability reasons (i) one or more (≥1) preventives failed, (ii) two or more (≥2) preventives failed and (iii) preventives were never used, or used but not failed (no prior failure). RESULTS: In an integrated analysis of EVOLVE studies, galcanezumab 120 mg/240 mg versus placebo led to larger overall mean (SE) reductions in monthly migraine headache days across 6 months in patients with prior preventive failures (P < 0.001): ≥1 failure: 120 mg: -4.0 (0.4); 240 mg: -4.2 (0.5); placebo: -1.3 (0.4); ≥2 failures: 120 mg: -3.1 (0.7); 240 mg: -3.8 (0.8); placebo: -0.5 (0.6). Similar results were observed amongst patients with no prior failure, but the placebo response was larger: 120 mg: -4.7 (0.2); 240 mg: -4.5 (0.2); placebo: -3.0 (0.2) (P < 0.001 versus placebo). Significant improvements were observed with galcanezumab versus placebo for ≥50% and ≥75% reduction in monthly migraine headache days. CONCLUSION: In patients with episodic migraine treated with galcanezumab, those with ≥1 or ≥2 prior preventive failures had significantly larger improvements, versus placebo, in efficacy outcomes. Similar results were observed in patients with no prior failure, with a larger placebo response.

Background: The United States Food and Drug Administration issued a black box warning on the mental health adverse effects of montelukast in 2020. Age-related effects on the risk of developing specific neuropsychiatric events in montelukast users remain largely unknown. Objective: To describe the risk of neuropsychiatric events associated with montelukast in adults and children with asthma. Methods: A systematic search of all studies investigating neuropsychiatric events in montelukast users was performed in PubMed, the Cochrane Library and Embase from inception to 7 September 2022. Animal studies and conference abstracts were excluded. Results: 59 studies (21 pharmacovigilance studies, four reviews from 172 randomised controlled trials, 20 observational studies, 10 case reports and four case series) evaluating neuropsychiatric events in patients with asthma on montelukast were reviewed. No significant association was shown between montelukast and suicide-related events in six of the observational studies. No association was found for depression as defined by the International Classification of Diseases 10 th revision codes in three observational studies and a review of randomised clinical trials. However, findings from four studies using antidepressant prescriptions as the outcome identified significant associations. Consistent with nine pharmacovigilance studies, two large-scale observational studies revealed possible associations of montelukast with anxiety and sleeping disorders in adult patients with asthma, respectively. However, the results were not replicated in two observational studies on children. Conclusion: Montelukast is not associated with suicide- and depression-related events in asthma patients. Older adults may be particularly susceptible to anxiety and sleeping disorders.

OBJECTIVE: To evaluate the measurement properties of all three domains of the Migraine-Specific Quality of Life questionnaire version 2.1 (MSQ v2.1) electronic patient-reported outcome (ePRO) to assess the functional impact of migraine in patients with episodic or chronic migraine (CM); and identify meaningful within-patient change thresholds for the Role Function-Restrictive (RFR), Role Function-Preventive (RFP), and Emotional Function (EF) domains. METHODS: Data were drawn from three double-blind, placebo-controlled, and randomized Phase 3 clinical studies (episodic migraine [EM]: EVOLVE-1 and EVOLVE-2; CM: REGAIN). The psychometric properties of the MSQ v2.1 ePRO domains were demonstrated by evaluating reliability (internal consistency and test-retest), construct validity (convergent and known groups), and responsiveness. Meaningful within-patient change thresholds for domains were estimated using anchor-based approaches, supplemented by empirical cumulative distribution function curves and probability density function plots to enable interpretation of meaningful change over 3 months. The Patient Global Impression of Severity (PGI-S) and Patient Global Impression of Improvement served as anchors. RESULTS: A total of 2,850 patients with either EM (EVOLVE-1: 851; EVOLVE-2: 909) or CM (REGAIN: 1,090) were included. The Cronbach's alpha estimates of internal consistency exceeded the recommended threshold of ≥0.70 for all domains from the three studies, indicating adequate internal consistency. Test-retest reliability intraclass correlation coefficients were ≥0.80 for all domains across all three studies, demonstrating almost perfect agreement. Convergent validity was supported by moderate-to-strong correlation (r ≥ 0.30) between all domains of MSQ v2.1 ePRO and studied anchors (Migraine Disability Assessment Score and PGI-S scores) across all three studies. Known group validity was established between all domains and subgroups of patients stratified by baseline PGI-S scores and baseline number of monthly migraine headache days for all three studies. The 3-month meaningful within-patient change thresholds were the same for EM and CM for RFP: 20.00 and EF: 26.67; and for RFR: 25.71. CONCLUSIONS: These findings demonstrate that all three domains of the MSQ v2.1 ePRO have sufficient reliability, validity, responsiveness, and appropriate interpretation standards. Our results suggest that MSQ v2.1 ePRO is a well-defined and reliable patient-reported outcome instrument that is suitable for use in clinical studies for evaluating the impact of migraine on patient functioning in episodic and CM.
