Theophylline can still have a role in the management of stable chronic obstructive pulmonary disease (COPD), but its use remains controversial, mainly due to its narrow therapeutic window. Doxofylline, another xanthine, is an effective bronchodilator and displays a better safety profile than theophylline. Therefore, we performed a quantitative synthesis to compare the efficacy and safety profile of different xanthines in COPD.The primary end-point of this meta-analysis was the impact of xanthines on lung function. In addition, we assessed the risk of adverse events by normalising data on safety as a function of person-weeks. Data obtained from 998 COPD patients were selected from 14 studies and meta-analysed using a network approach.The combined surface under the cumulative ranking curve (SUCRA) analysis of efficacy (change from baseline in forced expiratory volume in 1 s) and safety (risk of adverse events) showed that doxofylline was superior to aminophylline (comparable efficacy and significantly better safety), bamiphylline (significantly better efficacy and comparable safety), and theophylline (comparable efficacy and significantly better safety).Considering the overall efficacy/safety profile of the investigated agents, the results of this quantitative synthesis suggest that doxofylline seems to be the best xanthine for the treatment of COPD.

Background: Oral methylxanthines are effective drugs for the treatment of chronic obstructive respiratory disorders. The novel methylxanthine doxofylline, that has bronchodilator and anti-inflammatory activities, is not affected by the major drawback of theophylline. Nowadays large-scale quantitative synthesis comparing the efficacy and safety profile of doxofylline vs. theophylline in the treatment of asthma is still lacking. Therefore, we performed a quantitative synthesis to compare the efficacy/safety profile of doxofylline and theophylline in asthma. Methods: A pairwise and network meta-analyses were performed to assess the impact of doxofylline vs. theophylline and placebo on the change in asthma events, risk of adverse events (AEs), forced expiratory volume in 1 s (FEV1), and salbutamol use. Results: Data obtained from 696 asthmatic patients were extracted from 4 randomized controlled trials published between 2015 and 2018. Doxofylline was significantly (P < 0.05) more effective than theophylline in reducing the daily asthma events (mean difference − 0.14, 95%CI -0.27 – 0.00) and risk of AEs (relative risk 0.76, 95%CI 0.59–0.99). Doxofylline was as effective as theophylline in improving FEV1, and a trend of superiority (P = 0.058) was detected for doxofylline over theophylline with respect to the reduction in the use of salbutamol as rescue medication. The rank of effectiveness was doxofylline>theophylline> > placebo, and the rank of safety was placebo>doxofylline> > theophylline. Conclusions: Doxofylline is an effective and safe methylxanthine for the treatment of asthma, with an efficacy/ safety profile greater than that of theophylline.

Background: Chronic obstructive pulmonary disease (COPD) guidelines recommend both long-acting and dual bronchodilator therapy. It is unclear if there are differences in efficacy and safety. Objective: This meta-analysis evaluates the efficacy of dual therapy with long-acting β-agonist (LABA) + long acting muscarinic antagonist (LAMA) compared with monotherapy with LAMA for COPD. Methods: We searched PubMed, CINAHL, and Web of Science databases from inception through March 2020 to identify English-language, prospective randomized controlled trials (RCTs) that compared dual therapy with monotherapy in adult patients with COPD. Risk of bias was assessed using the Jadad score. Overall analysis was performed using Review Manager 5.3. Treatment effect was determined with the random-effects model using the Mantel-Haenszel method and was reported as mean difference (MD) with 95% CI. Results: A total of 18 RCTs were included (n = 6086; median Jadad score 5/5) that compared LAMA + LABA with LAMA. There was a greater improvement in forced expiratory volume at 1 s (FEV1) with dual therapy compared with LAMA: MD = 0.08; 95% CI = [0.05, 0.11]. There was no difference in St George Respiratory Questionnaire (SGRQ) scores between groups: OR = −0.85; 95% CI = [−1.83, 0.13]. There were no differences in overall adverse events (OR = 1.00; 95% CI = 0.92, 1.09), serious adverse events (OR = 1.01; 95% CI = 0.86, 1.18), or cardiovascular events (OR = 0.88; 95% CI = 0.58, 1.34). Conclusion and Relevance: Dual therapy improves FEV1 and is as safe as LAMA. Dual therapy does not improve SGRQ scores more than LAMA.

Nanoparticle albumin-bound paclitaxel (nab-paclitaxel) is an approved treatment for metastatic breast cancer (MBC). However, there is an ongoing debate about the efficacy and safety of nab-paclitaxel in elderly patients. We conducted a meta-analysis to evaluate nab-paclitaxel efficacy and adverse events in MBC patients 65 years and older, compared with MBC patients younger than 65 years (control group). We performed a literature search using PubMed, the Cochrane Library, and EMBASE, from their inception to 30 September 2019. The relevant studies compared overall response rates (ORRs) and incidence of adverse events; four studies comprising 1204 patients were identified and included. ORRs were similar in patients older than 65 years and controls (odds ratio (OR) 0.71, 95% confidence interval (CI) 0.42–1.21). On subgroup analysis, both first-line therapy (OR 2.54, 95% CI 1.92–3.36) and lower Eastern Cooperative Oncology Group (ECOG) performance status (OR 0.20, 95% CI 0.06–0.69) were associated with a higher ORR. Adverse events including neutropenia, sensory neuropathy, diarrhea, and nausea were comparable between the groups. In conclusion, nab-paclitaxel showed comparable efficacy and safety in older and younger patients with MBC. Nab-paclitaxel can be a first-line treatment option for MBC patients 65 years and older.

The efficacy and safety of twice-daily aclidinium bromide/formoterol fumarate was compared with that of salmeterol/fluticasone propionate in patients with stable, moderate-to-severe chronic obstructive pulmonary disease (COPD).AFFIRM COPD (Aclidinium and Formoterol Findings in Respiratory Medicine COPD) was a 24-week, double-blind, double-dummy, active-controlled study. Patients were randomised (1:1) to aclidinium/formoterol 400/12 µg twice-daily via Genuair/Pressair or salmeterol/fluticasone 50/500 µg twice-daily via Accuhaler. The primary end-point was peak forced expiratory volume in 1 s (FEV1) at week 24. Other end-points included Transition Dyspnoea Index (TDI) focal score at week 24, TDI and St George's Respiratory Questionnaire (SGRQ) responders, COPD Assessment Test and SGRQ scores, assessment of COPD symptoms and exacerbations, use of reliever medication, and device preference. Adverse events were monitored throughout.In total, 933 patients were eligible (mean age 63.4 years, 65.1% male). Aclidinium/formoterol was superior to salmeterol/fluticasone in peak FEV1 and noninferior in TDI. Health status and reduction in exacerbation risk were similar in both groups. While both treatments were well tolerated, pneumonia occurred less frequently with aclidinium/formoterol than salmeterol/fluticasone.In stable COPD, aclidinium/formoterol significantly improved bronchodilation versus salmeterol/fluticasone, with equivalent benefits in symptom control and reduction in exacerbation risk. Both treatments were well tolerated and treatment-related adverse events were less common with aclidinium/formoterol.

Background and Objective: We performed this systematic review and meta-analysis to assess the efficacy and safety of antigen-specific immunotherapy (Belagenpumatucel-L, MAGE-A3, L-BLP25, and TG4010) in the treatment of patients with non-small-cell lung cancer (NSCLC). </P><P> Methods: A comprehensive literature search on PubMed, Embase, and Web of Science was conducted. Eligible studies were clinical trials of patients with NSCLC who received the antigenspecific immunotherapy. Pooled hazard ratios (HRs) with 95% confidence intervals (95%CIs) were calculated for overall survival (OS), progression-free survival (PFS). Pooled risk ratios (RRs) were calculated for overall response rate (ORR) and the incidence of adverse events. </P><P> Results: In total, six randomized controlled trials (RCTs) with 4,806 patients were included. Pooled results showed that, antigen-specific immunotherapy did not significantly prolong OS (HR=0.92, 95%CI: 0.83, 1.01; P=0.087) and PFS (HR=0.93, 95%CI: 0.85, 1.01; P=0.088), but improved ORR (RR=1.72, 95%CI: 1.11, 2.68; P=0.016). Subgroup analysis based on treatment agents showed that, tecemotide was associated with a significant improvement in OS (HR=0.85, 95%CI: 0.74, 0.99; P=0.03) and PFS (HR=0.70, 95%CI: 0.49, 0.99, P=0.044); TG4010 was associated with an improvement in PFS (HR=0.87, 95%CI: 0.75, 1.00, P=0.058). In addition, NSCLC patients who were treated with antigen-specific immunotherapy exhibited a significantly higher incidence of adverse events than those treated with other treatments (RR=1.11, 95%CI: 1.00, 1.24; P=0.046). </P><P> Conclusion: Our study demonstrated the clinical survival benefits of tecemotide and TG4010 in the treatment of NSCLC. However, these evidence might be limited by potential biases. Therefore, further well-conducted, large-scale RCTs are needed to verify our findings.

ObjectiveTo give a comprehensive efficacy and safety ranking of different therapeutic regimens of ranibizumab for neovascular age-related macular degeneration (nAMD).DesignA systematic review and network meta-analysis.MethodsThe PubMed, Embase, Cochrane Central Register of Controlled Trials, and other clinical trial registries were searched up to 1 October 2019 to identify related randomised controlled trials (RCT) of different regimens of ranibizumab for nAMD. The primary efficacy outcome was the changes of best-corrected visual acuity (BCVA) at 1 year, the primary safety outcome was the incidence of severe ocular adverse events. Secondary outcomes such as changes of central retinal thickness (CRT) were evaluated. We estimated the standardised mean difference (SMD), ORs, 95% CIs, the surface under the cumulative ranking curves and the mean ranks for each outcome using network meta-analyses with random effects by Stata 14.0.ResultsWe identified 26 RCTs involving 10 821 patients with nAMD randomly assigned to 21 different therapeutic regimens of ranibizumab or sham treatment. Ranibizumab 0.5 mg (treat and extend, T&E) is most effective in terms of changes of BCVA (letters, SMD=21.41, 95% CI 19.86 to 22.95) and three or more lines of BCVA improvement (OR=2.83, 95% CI 1.27 to 4.38). However, it could not significantly reduce retreatment times compared with monthly injection (SMD=−0.94, 95% CI −2.26 to 0.39). Ranibizumab 0.5 mg (3+pro re nata)+non-steroidal anti-inflammatory drugs (NSAIDs) is most effective in reducing CRT and port delivery system of ranibizumab (100 mg/mL) could reduce the number of retreatment most significantly. All regimes have no more risk of severe ocular complications (including vitreous haemorrhage, rhegmatogenous retinal detachment, endophthalmitis, retinal tear and retinal pigment epithelium tear) or cardiocerebral vascular complications.ConclusionsRanibizumab 0.5 mg (T&E) is most effective in improving the visual outcome. The administration of topical NSAIDs could achieve additional efficacy in CRT reduction and visual improvement. Both interventions had acceptable risks of adverse events.

Abstract Background Idiopathic pulmonary fibrosis (IPF) predominantly affects individuals aged > 60 years who have several comorbidities. Nintedanib is an approved treatment for IPF, which reduces the rate of decline in forced vital capacity (FVC). We assessed the efficacy and safety of nintedanib in patients with IPF who were elderly and who had multiple comorbidities. Methods Data were pooled from five clinical trials in which patients were randomised to receive nintedanib 150 mg twice daily or placebo. We assessed outcomes in subgroups by age < 75 versus ≥ 75 years, by < 5 and ≥ 5 comorbidities, and by Charlson Comorbidity Index (CCI) ≤ 3 and > 3 at baseline. Results The data set comprised 1690 patients. Nintedanib reduced the rate of decline in FVC (mL/year) over 52 weeks versus placebo in patients aged ≥ 75 years (difference: 105.3 [95% CI 39.3, 171.2]) (n = 326) and < 75 years (difference 125.2 [90.1, 160.4]) (n = 1364) (p = 0.60 for treatment-by-time-by-subgroup interaction), in patients with < 5 comorbidities (difference: 107.9 [95% CI 65.0, 150.9]) (n = 843) and ≥ 5 comorbidities (difference 139.3 [93.8, 184.8]) (n = 847) (p = 0.41 for treatment-by-time-by-subgroup interaction) and in patients with CCI score ≤ 3 (difference: 106.4 [95% CI 70.4, 142.4]) (n = 1330) and CCI score > 3 (difference: 129.5 [57.6, 201.4]) (n = 360) (p = 0.57 for treatment-by-time-by-subgroup interaction). The adverse event profile of nintedanib was generally similar across subgroups. The proportion of patients with adverse events leading to treatment discontinuation was greater in patients aged ≥ 75 years than < 75 years in both the nintedanib (26.4% versus 16.0%) and placebo (12.2% versus 10.8%) groups. Similarly the proportion of patients with adverse events leading to treatment discontinuation was greater in patients with ≥ 5 than < 5 comorbidities (nintedanib: 20.5% versus 15.7%; placebo: 12.1% versus 10.0%). Conclusions Our findings suggest that the effect of nintedanib on reducing the rate of FVC decline is consistent across subgroups based on age and comorbidity burden. Proactive management of adverse events is important to reduce the impact of adverse events and help patients remain on therapy. Trial registration: ClinicalTrials.gov NCT00514683, NCT01335464, NCT01335477, NCT02788474, NCT01979952.

Background: Chronic obstructive pulmonary disease (COPD) is a progressive condition characterized by chronic airway inflammation and lung parenchyma damage. Systemic inflammation and oxidative stress also play a role in the pathogenesis of COPD. Serum albumin is a negative acute-phase protein with antioxidant effects and an important marker of malnutrition. The aim of this meta-analysis was to investigate differences in serum albumin concentrations between patients with stable COPD and non-COPD subjects. Methods: A systematic search was conducted, using the terms “albumin” and “chronic obstructive pulmonary disease” or “COPD”, in the electronic databases PubMed and Web of Science, from inception to May 2020. Results: Twenty-six studies were identified on a total of 2554 COPD patients and 2055 non-COPD controls. Pooled results showed that serum albumin concentrations were significantly lower in COPD patients (standard mean difference, SMD = −0.50, 95% CI −0.67 to −0.32; p < 0.001). No significant differences were observed in SMD of serum albumin concentrations between COPD patients with forced expiratory volume in the 1st second (FEV1) < 50% and those with FEV1 > 50%. Conclusions: Our systematic review and meta-analysis showed that serum albumin concentrations are significantly lower in patients with stable COPD compared to non-COPD controls. This supports the presence of a deficit in systemic anti-inflammatory and antioxidant defense mechanisms in COPD.

ABSTRACTPurposeof Review: To investigate the efficacy and safety of CVT-301 for motor fluctuation in Parkinson’s disease (PD).Recent Findings:This study demonstrated that the CVT-301 group had a higher proportion of patients achieving an ON state than the placebo group (OR=2.68; 95% CI: 1.86-3.86; p<0.00001). Moreover, CVT-301 had also shown to improve motor function by UPDRS-III score (SMD=3.83; 95% CI: 2.44-5.23; p<0.00001) and promote an overall improvement of PD by PGIC self-rating (OR=2.95; 95% CI: 1.78-4.9; p<0.00001). The most common adverse events encountered were respiratory symptoms (OR=12.18; 95% CI: 5.01-29.62; p<0.00001) and nausea (OR=3.95; 95% CI: 1.01-15.41; p=0.05).Summary:CVT-301 had the potential to be an alternative or even a preferred treatment for motor fluctuation in PD patients.
