Safety and efficacy of elagolix (with and without add-back therapy) for the treatment of heavy menstrual bleeding associated with uterine leiomyomas: a systematic review and meta-analysis

Abstract Background Heavy menstrual bleeding (HMB) is a common clinical finding in patients with uterine leiomyomas that can negatively impact their quality of life. Recently, a novel oral GnRH-antagonist (elagolix) has emerged as a possible therapeutic agent for this ailment. Herein data was pooled from clinical trials assessing the safety and efficacy of elagolix with and without add-back therapy. Main text PubMed and Cochrane library were systematically searched for RCTs that measured the efficacy and safety of elagolix for the treatment of uterine fibroid-associated HMB. All safety and efficacy endpoints were compared between elagolix-alone, elagolix w/add-back therapy, and placebo. The primary efficacy endpoint was defined as the number of women who achieved menstrual blood loss (MBL) < 80 ml and a reduction in MBL from baseline of > 50% at the end of treatment. Secondary outcomes assessed included change in hemoglobin levels, incidence suppression of bleeding and amenorrhea, and the incidence of adverse events. The random effects model was used to pool data, and heterogeneity was assessed using I2. Our search identified 4 clinical trials meeting our PICO criteria, with a total of 916 patients. Analysis of the primary outcome revealed that elagolix-alone was the most effective treatment compared to both placebo (LOR = 3.47, CI = 3.03–3.91, p = 0.000, I2 = 0.0%) and add-back therapy (LOR = 0.64, CI = 0.12–1.16, p = 0.016, I2 = 43.1%). Furthermore, both elagolix groups (irrespective of add-back therapy) observed a significant improvement in post-treatment hemoglobin levels as compared to the placebo group (elagolix-alone vs PBO: LOR = 1.44, CI = 0.66–2.22, I2 = 66.0%, p = 0.000; elagolix-w/add-back therapy vs PBO: LOR = 1.22, CI = 0.78–1.66, I2 = 0.0%, p = 0.000). Concerning safety, while elagolix without add-back therapy had the highest overall incidence of adverse effects (elagolix-alone vs placebo LOR = 0.84, CI = 0.48–1.20, I2 = 7.8%, p = 0.000; elagolix-alone vs elagolix-w/add-back LOR = 0.68, CI = 0.09–1.26, p = 0.024, I2 = 64.6%), the incidence of serious (life threatening) adverse events between all 3 treatment groups was not statistically different. The inclusion of add-back therapy with elagolix made the treatment noticeably safer (elagolix-w/add-back vs placebo: LOR = 0.19, CI = − 0.10 to 0.48, I2 = 0.0%, p = 0.194) without seriously compromising its efficacy. Conclusion High-quality evidence from 4 trials suggests that elagolix is an effective treatment for leiomyoma-associated HMB, with a marked improvement in all efficacy endpoints. Furthermore, the inclusion of add-back therapy in the treatment regimen should be considered as it mitigates the hypoestrogenic effects of elagolix.

Background: Nervous and muscular adverse events (NMAEs) have garnered considerable attention after the vaccination against coronavirus disease (COVID-19). However, the incidences of NMAEs remain unclear. We aimed to calculate the pooled event rate of NMAEs after COVID-19 vaccination. Methods: A systematic review and meta-analysis of clinical trials on the incidences of NMAEs after COVID-19 vaccination was conducted. The PubMed, Medline, Embase, Cochrane Library, and Chinese National Knowledge Infrastructure databases were searched from inception to 2 June 2021. Two independent reviewers selected the study and extracted the data. Categorical variables were analyzed using Pearson’s chi-square test. The pooled odds ratio (OR) with the corresponding 95% confidence intervals (CIs) were estimated and generated with random or fixed effects models. The protocol of the present study was registered on PROSPERO (CRD42021240450). Results: In 15 phase 1/2 trials, NMAEs occurred in 29.2% vs. 21.6% (p < 0.001) vaccinated participants and controls. Headache and myalgia accounted for 98.2% and 97.7%, and their incidences were 16.4% vs. 13.9% (OR = 1.97, 95% CI = 1.28–3.06, p = 0.002) and 16.0% vs. 7.9% (OR = 3.31, 95% CI = 2.05–5.35, p < 0.001) in the vaccine and control groups, respectively. Headache and myalgia were more frequent in the newly licensed vaccines (OR = 1.97, 95% CI = 1.28–3.06, p = 0.02 and OR = 3.31, 95% CI = 2.05–5.35, p < 0.001) and younger adults (OR = 1.40, 95% CI = 1.12–1.75, p = 0.003 and OR = 1.54, 95% CI = 1.20–1.96, p < 0.001). In four open-label trials, the incidences of headache, myalgia, and unsolicited NMAEs were 38.7%, 27.4%, and 1.5%. Following vaccination in phase 3 trials, headache and myalgia were still common with a rate of 29.5% and 19.2%, although the unsolicited NMAEs with incidence rates of ≤ 0.7% were not different from the control group in each study. Conclusions: Following the vaccination, NMAEs are common of which headache and myalgia comprised a considerable measure, although life-threatening unsolicited events are rare. NMAEs should be continuously monitored during the ongoing global COVID-19 vaccination program.

Abstract Background Fremanezumab (TEV-48125) is a fully humanized immunoglobulin G isotype 2a selective monoclonal antibody that potently binds to calcitonin gene-related peptide (CGRP). It is one of novel therapeutic drugs for the prevention of migraine, which is one of the most common neurological diseases worldwide. Several clinical trails have been conducted to investigate the safety and efficacy of fremanezumab, but there is no systematic review of existing literature has been performed. Hence, we performed a meta-analysis to investigate the efficacy and safety of fremanezumab for prevention of migraine. Method Pubmed (MEDLINE), Embase, and Cochrane Library were searched from January 2001 to August 2019 for randomized controlled trials (RCTs). Five RCTs with 3379 patients were finally included in our study. Result We pooled 3379 patients from 5 RCTs, the primary endpoints were mean monthly migraine and headache days, baseline to week 12. We found that fremanezumab led to a significant reduction in migraine days (P < 0.0001) and headache days (P < 0.0001) during 12 weeks compared with placebo. In addition, after using fremanezumab, the risk of at least one adverse event (P=0.001) or related to the trail regimen (P=0.0005) significantly increase compared with placebo. Conclusions Fremanezumab has good efficacy for the prevention of migraine. The administration of fremanezumab can cause some mild adverse events but not serious adverse events.

Abstract Introduction Bortezomib, a proteasome inhibitor and lenalidomide (Len), an immunomodulatory drug are the backbone of established treatment regimens for newly diagnosed MM. Patients with dual-refractory (refractory to both bortezomib and lenalidomide) disease have a poor prognosis with overall survival estimated to be less than one year. Pomalidomide (Pom) has distinct anticancer, antiangiogenic and immunomodulatory properties and has demonstrated synergistic antiproliferative activity in combination regimens. The aim of our study is to compare different Pom based regimens to identify the most effective regimen for relapsed refractory multiple myeloma (RRMM) patients. Methods A comprehensive literature search was performed on PubMed, Cochrane library, Web of Science, Embase and AdisInsight databases on 03/29/2018 which identified a total of 1374 studies. We included phase II/III clinical trials on pomalidomide based regimens that have clearly documented efficacy outcomes. All statistical analyses were performed using Comprehensive Meta-analysis (CMA) Version 3. We used the Cochrane Q statistics (p<0.05 considered significant) and I2 index to calculate the degree of heterogeneity of the studies. A random effect model was used if there was significant heterogeneity (p>0.05 or I2 >50%). Studies were classified into subgroups according to the therapeutic regimen: dual and triplet combinations. A separate stratified analysis of triplet regimens based on type of regimen was also performed. Results A total of 35 studies (n = 4623 patients) were included. The most commonly studied regimen was Pom + LoDex (Low dose dexamethasone) with a total of 16 studies on this regimen. All patients included in our study had ≥ 2 prior lines of therapy. Mean number of prior lines of therapy was 6. Most patients were lenalidomide refractory, with 10 patient cohorts of 100% refractoriness and 8 cohorts of ≥ 90% refractoriness. Pooled analysis showed an overall response rate (ORR) of 47.1% across all Pom regimens including both doublet and triplet regimens. An I2 value of 87.3 was found, indicating high heterogeneity across all Pom regimens. With Pom-LoDex, pooled ORR was found to be 35.7% and mean OS 14.37 months. With triplet regimens, pooled ORR was found to be 61.9%. In a separate stratified analysis of triplet regimens based on type of regimen, pooled ORRs with few selected regimens were as follows; Bort-Pom-LoDex (pooled ORR 83.5%, mean PFS 15.7 months [mos]), CFZ-Pom-LoDex (pooled ORR 77.1%, mean PFS 15.3 mos), Pom-LoDex-bendamustine (pooled ORR 74.2%), Pom-Dex-daratumumab (pooled ORR 64.5%), Pom-LoDex-cyclophosphamide (pooled ORR 59.4%, mean PFS 9.5 mos), Pom-LoDex-doxorubicin (pooled ORR 32%). Most frequently reported adverse event with Pom based regimens was myelosuppression. Mean incidences of grade ≥3 hematologic adverse events were neutropenia (47.6%), anemia (26.5%), and thrombocytopenia (20.8%). Mean incidences of grade ≥3 non-hematologic adverse events were infections (29.1%), pneumonia (13.8%) and fatigue (10%). Most of the studies used pomalidomide 4mg daily dosing. Lacy et al. suggested no advantage of 4mg pomalidomide over 2 mg daily dosing. Conclusion From results of pooled analysis, we can infer that triplet combinations of Pom yield almost double response rates (pooled ORR 61.9%) when compared to dual combination of Pom-LoDex (pooled ORR 35.7%). Among three drug combinations, Bort-Pom-LoDex (pooled ORR 83.5%) and CFZ-Pom-LoDex (pooled ORR 77.1%) seem to produce better outcomes. Our study provides useful insight into relative efficacy of various Pom regimens for treatment of RRMM patients. Several trials involving various MoAbs like nivolumab, daratumumab, elotuzumab, isatuximab and pembrolizumab in combination with Pom-LoDex are currently ongoing. Pomalidomide has an acceptable safety profile. Most common treatment emergent adverse events were myelotoxicity and infections that can be effectively managed with supportive care and dose modifications.

Objectives. The aim of this study was to provide the first study to systematically analyze the efficacy and safety of PCSK9-mAbs in the treatment of familial hypercholesterolemia (FH). Methods. A computer was used to search the electronic Cochrane Library, PubMed/MEDLINE, and Embase databases for clinical trials using the following search terms: “AMG 145”, “evolocumab”, “SAR236553/REGN727”, “alirocumab”, “RG7652”, “LY3015014”, “RN316/bococizumab”, “PCSK9”, and “familial hypercholesterolemia” up to November 2020. Study quality was assessed with the Cochrane Collaboration’s tool, and publication bias was evaluated by a contour-enhanced funnel plot and the Harbord modification of the Egger test. After obtaining the data, a meta-analysis was performed using R software, version 4.0.3. Results. A meta-analysis was performed on 7 clinical trials (926 total patients). The results showed that PCSK9-mAbs reduced the LDL-C level by the greatest margin, WMD −49.14%, 95% CI: −55.81 to −42.47%, on FH versus control groups. PCSK9-mAbs also significantly reduced lipoprotein (a) (Lp (a)), total cholesterol (TC), triglycerides (TG), apolipoprotein-B (Apo-B), and non-high-density lipoprotein cholesterol (non-HDL-C) levels and increased HDL-C and apolipoprotein-A1 (Apo-A1) levels of beneficial lipoproteins. Moreover, no significant difference was found between PCSK9-mAbs treatment and placebo in common adverse events, serious events, and laboratory adverse events. Conclusion. PCSK9-mAbs significantly decreased LDL-C and other lipid levels with satisfactory safety and tolerability in FH treatment.

Abstract Background Uterine leiomyomas are the most common neoplasm affecting women and frequently cause heavy menstrual bleeding and pain. Gonadotropin-releasing hormone (GnRH) receptor antagonists provide fast symptom relief and show promise as a medical (non-surgical) treatment option and as a presurgical treatment to reduce leiomyoma size. The aim of this study was to evaluate the efficacy and safety of three dose levels of oral relugolix, a small molecule GnRH receptor antagonist, in Japanese women with uterine leiomyomas and heavy menstrual bleeding. Methods This phase 2, multicenter, double-blind, parallel-group study was conducted at 36 sites in Japan in women with uterine leiomyomas and heavy menstrual bleeding, defined as a pictorial blood loss assessment chart (PBAC) score of ≥ 120 in one menstrual cycle. Patients were randomized 1:1:1:1 to relugolix 10, 20, or 40 mg, or placebo, orally once daily for 12 weeks. The primary endpoint was the proportion of patients with a total PBAC score of < 10 from week 6 to 12. A sample size of 50 patients per group was estimated to provide ≥ 95% power, based on the comparison of relugolix 40 mg with placebo using a chi-square test with a significance level of 5% (two-sided). Results From November 2011 to September 2012, 216 patients were randomized and 214 patients (99.1%) were analyzed. The proportion (difference vs. placebo) of patients that achieved the primary endpoint in the placebo and 10-, 20-, and 40-mg relugolix groups were 0%, 20.8% (95% confidence interval [CI]: 9.3–32.3, P < .001), 42.6% (95% CI: 29.4–55.8, P < .001), and 83.3% (95% CI: 73.4–93.3, P < .001), respectively. Though treatment-emergent adverse events were similar between the 20- and 40-mg groups, the incidence rates were more frequent compared with the placebo group. Most of these adverse events were mild or moderate in intensity. Conclusions Relugolix decreased menstrual blood loss in women with uterine leiomyomas in a dose–response manner, and was generally well tolerated.

AbstractObjectiveThe aim of this systematic review is to evaluate the data currently available regarding the repurposing of different drugs for Covid-19 treatment. Participants with suspected or diagnosed Covid-19 will be included. The interventions being considered are drugs being repurposed, and comparators will include standard of care treatment or placebo.MethodsWe searched Ovid-MEDLINE, EMBASE, Cochrane library, clinical trial registration site in the UK(NIHR), Europe (clinicaltrialsregister.eu), US (ClinicalTrials.gov) and internationally (isrctn.com), and reviewed the reference lists of articles for eligible articles published up to April 22, 2020. All studies in English that evaluated the efficacy of the listed drugs were included. Cochrane RoB 2.0 and ROBINS-I tool were used to assess study quality. This systematic review adheres to the PRISMA guidelines. The protocol is available at PROSPERO (CRD42020180915).ResultsFrom 708 identified studies or clinical trials, 16 studies and 16 case reports met our eligibility criteria. Of these, 6 were randomized controlled trials (763 patients), 7 cohort studies (321 patients) and 3 case series (191 patients). Chloroquine (CQ) had a 100% discharge rate compared to 50% with lopinavir-ritonavir at day 14, however a trial has recommended against a high dosage due to cardiotoxic events. Hydroxychloroquine (HCQ) has shown no significant improvement in negative seroconversion rate which is also seen in our meta-analysis (p=0.68). Adverse events with HCQ have a significant difference compared to the control group (p=0.001). Lopinavir-ritonavir has shown no improvement in time to clinical improvement which is seen in our meta-analyses (p=0.1). Remdesivir has shown no significant improvement in time to clinical improvement but this trial had insufficient power.DiscussionDue to the paucity in evidence, it is difficult to establish the efficacy of these drugs in the treatment of Covid-19 as currently there is no significant clinical effectiveness of the repurposed drugs. Further large clinical trials are required to achieve more reliable findings. A risk-benefit analysis is required on an individual basis to weigh out the potential improvement in clinical outcome and viral load reduction compared to the risks of the adverse events. (1-16)

Abstract Background: Elotuzumab (elo) is a humanized monoclonal antibody, which has been approved by the FDA for use in combination with lenalidomide (lena) and dexamethasone (dexa) in patients (pts) with relapsed and refractory multiple myeloma (RRMM). Elotuzumab is effective as a single agent, as well as in combination for multiple myeloma treatments, supporting the use of elo in pts with RRMM and newly diagnosed multiple myeloma (NDMM) pts. Method: After review of literature using database searches was done on 6/27/18 (Pubmed, Embase, Cochrane Library, Web of Science and Clinical Trials.gov), 9 prospective and 1 retrospective study with 1128 enrolled pts met the inclusion criteria to date in RRMM and 2 clinical trials including 123 pts in NDMM (Table 1). CMA software v.3 was used for meta-analysis. A random-effect model was applied. Result: Regimens used in RRMM: Based on pooled analysis (95% CI), an overall response rate (ORR) of 66% (54-76.2) was calculated in 685 evaluable pts treated with elo based regimens in RRMM (Figure 1). Most common grade (G) ≥ 3 hematological adverse events (HAE) and non-hematological adverse events (NHAE) based on regimen were calculated using pooled analysis in RRMM pts (Table 2). Anemia was noted in 12.1% ( 7.7-18.6) in 559 pts, while neutropenia in 14.5% (7.5-26.4) out of 591 pts and thrombocytopenia (tcp) in 11.9% (7.9-17.4) in 198 evaluable pts. Diarrhea 5.5% (3.6-8.3), pyrexia 2.4% (1.5-4), peripheral neuropathy (PN) 8.4% (3.8-17.8) were measured in 626, 668 and 143 pts respectively. Elotuzumab as monotherapy: 1 study (n=34) evaluated the efficacy of elo as single agent in RRMM. The median age, time from diagnosis and number of prior therapies were 64.5 years (y) (46-87), 4.4 y (0.9-12.8) and 4.5 y (2-10) respectively. It produced an ORR of 1.4% (0.1-19.1 95% CI) in 34 evaluable pts. Adverse events recorded were pyrexia and fatigue in 17.6% and 8.8% pts respectively. Elotuzumab in two drug regimen: In RRMM, 2 clinical trials (n=49) evaluated the efficacy (95% CI) of elo, ORR of 25% (4.1-72.3) was calculated. The best PFS (progression free survival) produced was in combination of elo 20 mg with bortezumib (bort) 1.3mg/m2 of 9.46 months as compared to 1.8 months when elo10mg/kg + dexamethasone (dexa) 28mg was used. In our analysis for safety, common G≥ 3 HAE calculated were, thrombocytopenia 8.7% (3.3-21.1) n=49, neutropenia 10.7 % (3.5-28.4) n=28 pts and anemia 7.1% (1.8-24.5) n=28 pts. NHAE included diarrhea 1.7% (0.1-22.3), PN 10.7% (3.5-28.4), pyrexia 1.7% (0.1-22.3) in 28 evaluable pts each. Elotuzumab in three drug regimen: In RRMM, 10 clinical trials including 602 pts evaluated the efficacy of elo as a part of triple drug regimen, producing an ORR of 72.2% (54-76.2). The best results were produced with the combination of elo 10-20mg/kg + lenalidomide (lena) 25mg + dexa 40mg producing a PFS of 32.2 mo and 28.62 mo in its phase I and II cohorts respectively. Based on pooled analysis (95% CI) common HAE calculated were neutropenia 17.5% (7.6-35.4) in n=563, thrombocytopenia 12.7% (8.2-19.4) in n=149 and anemia 13% (8-20.5) in n=531 pts. Common G ≥ 3 NHAE estimated were diarrhea 5.7% (3.7-8.6), PN 6.6% (2-19.2), pyrexia 2.5% (1.5-4.1) in 598, 115 and 640 pts respectively. Elotuzumab based regimen in NDMM: A currently ongoing clinical trial NCT02272803 has produced promising results in NDMM pts. As a part of three drug regimen with dose of elo 10mg/kg-20mg/kg, lena 25mg, dexa 20mg in 40 pts produced an ORR of 87.5% (73.2-95.8) versus control group of lena 25mg plus dexa 40mg in 42 pts with an ORR of 73.8% (58-86.1). The PFS rate recorded at 1 year was 93% (79-98%) and 91% (73-97%) respectively. The HAE G ≥ 3 included, neutropenia 18% and leukopenia 15%. In another study with 41 pts, elo was used in combination with lena, bort and dexa producing an ORR of 100% and greater than grade 3 adverse events including Tcp 15%, PN 2%. Conclusion: Results produced in our study suggest that elotuzumab is highly effective when used in pts with RRMM and NDMM. Combination regimens for elo produces an ORR ranging from 79-83% with elo + lena+ dexa, proving that the best results were produced by three drug regimens. Large prospective studies are required to evaluate efficacy and safety of elotuzumab in combination therapies. Disclosures No relevant conflicts of interest to declare.

Specific Symptoms

BackgroundAnti-interleukin (IL)-23 agents are widely used for autoimmune disease treatment; however, the safety and risks of specific symptoms have not been systematically assessed.ObjectivesThe aim of this study was to summarize the characteristics and mechanisms of occurrence of five immunological and non-immunological adverse events caused by different anti-IL-23 agents.MethodsThe Cochrane Library, EMBASE, PubMed, and Web of Science databases were searched for eligible randomized clinical trials published from inception through May 1, 2020. Randomized clinical trials that reported at least one type of adverse event after treatment were included, regardless of sex, age, ethnicity, and diagnosis. Two investigators independently screened and extracted the characteristics of the studies, participants, drugs, and adverse event types. The Cochrane Handbook was used to assess the methodological quality of the included randomized clinical trials. Heterogeneity was assessed using the I2 statistic. Meta-regression was applied to determine the sources of heterogeneity, and subgroup analysis was used to identify the factors contributing to adverse events.ResultsForty-eight studies were included in the meta-analysis, comprising 25,624 patients treated with anti-IL-23 agents. Serious immunological or non-immunological adverse events were rare. Anti-IL-12/23-p40 agents appeared to cause adverse events more easily than anti-IL-23-p19 agents. The incidence of cancer did not appear to be related to anti-IL-23 agent treatment, and long-term medication could lead to mental diseases. The prevention of complications should be carefully monitored when administered for over approximately 40 weeks to avoid further adverse reactions, and the incidence of infection was the highest among general immunological adverse events.ConclusionsThe application of anti-IL-23 agents induced a series of immunological and non-immunological adverse events, but these agents tend to be well-tolerated with good safety profiles.

Purpose: To evaluate the safety and efficacy of remdesivir in adult patients with COVID-19. Methods: PubMed, Embase, Scopus, Web of Science, Cochrane Library, ClinicalTrials.gov, and medRxiv databases were searched using a search strategy tailored to each database. The Consolidated Standards of Reporting Trials (CONSORT) and Strengthening the reporting of observational studies in epidemiology (STROBE) checklists were used for the studies' qualitative assessment. The outcomes studied were mortality, all adverse events, serious adverse events, and clinical improvement. The quantitative synthesis was conducted using fixed and random effects models in the CMA 2.2. Heterogeneity was tested using the I-squared (I2) measure. Results: In general, six studies, including five randomized controlled trials and one cohort study were found eligible. Comparison of the findings related to both groups receiving remdesivir (10-day remdesivir group) and placebo/control group showed that remdesivir treatment had no significant effect on mortality at day 14 of the treatment (RR=0.769; 95% CI :0.563-1.050; p=0.098), and all adverse events (RR= 1.078; 95% CI: 0.908-1.279; p= 0.392). However, remdesivir had a significant effect on clinical improvement at day 14 compared to placebo/control (OR= 1.447; 95% CI: 1.005-2.085; p= 0.047) and reduced serious adverse events (RR= 0.736; 95% CI: 0.611-0.887; p= 0.001). Conclusion: Remdesivir has positive effects on clinical improvement, and reduction of the risk of serious adverse events. However, it does not influence the mortality at day 14 of treatment.

Introduction. Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) imposes a large burden on economy and society worldwide. In addition to western medicine, multiple kinds of qi-tonifying Chinese medicine injections have been widely used in China as adjunctive treatments. Previous small-sample clinical trials have proven their efficacy in the treatment of AECOPD. However, data on comparative effectiveness and safety of qi-tonifying injections are limited. We conducted this network meta-analysis to compare the efficacy and safety of 7 commonly used qi-tonifying injections in patients with AECOPD. Methods. Literature search was conducted through electronic databases, including PubMed, the Cochrane Library, EMBASE, CINAHL, AMED, CBM, CNKI, Wanfang database, and VIP database. Randomized clinical trials (RCTs) exploring the efficacy of any of these 7 qi-tonifying injections were included. The primary outcome was lung function (FEV1 and FVC). R 4.0.0 and STATA 12.0 were adopted to perform the network meta-analysis using Bayesian statistics. Results. A total of 36 RCTs involving 2657 participants were included. The results of network meta-analyses indicated that Chuankezhi injection (CKZ) combined with routine treatment (RT) was superior to other qi-tonifying injections combined with RT in terms of FEV1 improvement (MD = 0.63, 95% CI: 0.22, 1.04). For improving FVC, Shengmai injection (SGM) combined with RT showed the greatest therapeutic effect (MD = 0.38, 95% CI: 0.13, 0.61). Moreover, SGM combined with RT revealed the best estimates for response rate (MD = 4.00, 95% CI: 1.34, 13.63). The main adverse events in this study were gastrointestinal reactions and injection site reactions. No serious adverse events were reported. Conclusion. In this network meta-analysis, SGM and CKZ were potential best adjunctive therapies in the treatment of AECOPD.
