Abstract Background The anti-malarial drug, amodiaquine, a commonly used, long-acting partner drug in artemisinin-based combination therapy, is metabolized to active desethyl-amodiaquine (DEAQ) by cytochrome P450 2C8 (CYP2C8). The CYP2C8 gene carries several polymorphisms including the more frequent minor alleles, CYP2C8*2 and CYP2C8*3. These minor alleles have been associated with decreased enzymatic activity, slowing the amodiaquine biotransformation towards DEAQ. This study aimed to assess the influence of these CYP2C8 polymorphisms on the efficacy and tolerability of artesunate–amodiaquine (AS–AQ) treatment for uncomplicated Plasmodium falciparum malaria in Zanzibar. Methods Dried blood spots on filter paper were collected from 618 children enrolled in two randomized clinical trials comparing AS–AQ and artemether-lumefantrine in 2002–2005 in Zanzibar. Study participant were under five years of age with uncomplicated falciparum malaria. Human CYP2C8*2 and CYP2C8*3 genotype frequencies were determined by PCR-restriction fragment length polymorphism. Statistical associations between CYP2C8*2 and/or CYP2C8*3 allele carriers and treatment outcome or occurrence of adverse events were assessed by Fisher’s exact test. Results The allele frequencies of CYP2C8*2 and CYP2C8*3 were 17.5 % (95 % CI 15.4–19.7) and 2.7 % (95 % CI 1.8–3.7), respectively. There was no significant difference in the proportion of subjects carrying either CYP2C8*2 or CYP2C8*3 alleles amongst those with re-infections (44.1 %; 95 % CI 33.8–54.8) or those with recrudescent infections (48.3 %; 95 % CI 29.4–67.5), compared to those with an adequate clinical and parasitological response (36.7 %; 95 % CI 30.0-43.9) (P = 0.25 and P = 0.31, respectively). However, patients carrying either CYP2C8*2 or CYP2C8*3 alleles were significantly associated with an increased occurrence of non-serious adverse events, when compared with CYP2C8 *1/*1 wild type homozygotes (44.9 %; 95 % CI 36.1–54.0 vs. 28.1 %; 95 % CI 21.9–35.0, respectively; P = 0.003). Conclusions CYP2C8 genotypes did not influence treatment efficacy directly, but the tolerability to AS–AQ may be reduced in subjects carrying the CYP2C8*2 and CYP2C8*3 alleles. The importance of this non-negligible association with regard to amodiaquine-based malaria chemotherapy warrants further investigation.

Introduction: Remdesivir, an experimental antiviral drug has shown to inhibit severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), both in vitro and in vivo. The present systematic review and meta-analysis were performed to quantify the safety and tolerability of remdesivir, based on safety outcome findings from randomized controlled trials, observational studies and case reports of remdesivir in coronavirus disease 2019 (COVID-19) patients. Methods: We have performed a systematic search in the PubMed, Google Scholar and Cochrane Library using specific keywords such as ‘COVID-19’ OR ‘SARS CoV-2’ AND ‘Remdesivir’. The study endpoints include total adverse events (AEs), serious adverse events (SAEs), grade 3 and grade 4 AEs, mortality and drug tolerability. Statistical analysis was carried out by using Revman 5.4 software. Results: Total 15 studies were included for systematic review, but only 5 randomized clinical trials (RCTs) ( n = 13,622) were included for meta-analysis. Visual inspection of the forest plots for remdesivir 10-day versus placebo and remdesivir 10-day versus 5-day groups revealed that there is a significant difference in SAEs [10-day remdesivir versus control (odds ratio [OR] = 0.55, 0.40–0.74) p = 0.0001; I2 = 0%; 10-day remdesivir versus 5-day remdesivir (OR = 0.56, 0.38–0.84) p = 0.005; I2 = 13%]. In grade 4 AEs, there is a significant difference in 10-day remdesivir versus control (OR = 0.32, 0.19–0.54) p = 0.0001; I2 = 0%, but not in comparison to 5-day remdesivir (OR = 0.95, 0.59–1.54) p = 0.85; I2 = 0%. But there is no significant difference in grade 3 AEs [remdesivir 10 day versus control (OR = 0.81, 0.59–1.11) p = 0.19; I2 = 0%; 10-day remdesivir versus 5-day remdesivir (OR = 1.24, 0.86–1.80) p = 0.25; I2 = 0%], in total AEs [remdesivir 10 day versus control (OR = 1.07, 0.66–1.75) p = 0.77; I2 = 79%; remdesivir 10 day versus 5 day (OR = 1.08, 0.70–1.68) p = 0.73; I2 = 54%)], in mortality [10-day remdesivir versus control (OR = 0.93, 0.80–1.08) p = 0.32; I2 = 0%; 10-day remdesivir versus 5-day remdesivir (OR = 1.39, 0.73–2.62) p = 0.32; I2 = 0%)] and tolerability [remdesivir 10 day versus control (OR = 1.05, 0.51–2.18) p = 0.89; I2 = 65%, 10-day remdesivir versus 5-day remdesivir (OR = 0.86, 0.18–4.01) p = 0.85; I2 = 78%]. Discussion & Conclusion: Ten-day remdesivir was a safe antiviral agent but not tolerable over control in the hospitalized COVID-19 patients with a need of administration cautiousness for grade 3 AEs. There was no added benefit of 10- or 5-day remdesivir in reducing mortality over placebo. To avoid SAEs, we suggest for prior monitoring of liver function tests (LFT), renal function tests (RFT), complete blood count (CBC) and serum electrolytes for those with preexisting hepatic and renal impairments and patients receiving concomitant hepatotoxic or nephrotoxic drugs. Furthermore, a number of RCTs of remdesivir in COVID-19 patients are suggested. Plain Language Summary Ten-day remdesivir is a safe antiviral drug with common adverse events in comparison to placebo. The rate of serious adverse events and grade 3 adverse events were significantly lower in 10-day remdesivir in comparison to placebo/5-day remdesivir. There was no significant difference in the rate of tolerability and mortality reduction in 10-day remdesivir over placebo/5-day remdesivir. There were no new safety signals reported in vulnerable populations, paediatric, pregnant and lactating women.

Abstract Background: Despite the expectations regarding the effectiveness of chloroquine (CQ) and hydroxychloroquine (HCQ) for coronavirus disease (COVID-19) management, concerns about their adverse events have remained. Objectives: The objective of this systematic review was to evaluate the safety of CQ and HCQ from malarial and non-malarial randomized clinical trials (RCTs). Methods: The primary outcomes were the frequencies of serious adverse events (SAEs), retinopathy, and cardiac complications. Search strategies were applied to MEDLINE, EMBASE, LILACS, CENTRAL, Scopus, and Trip databases. We used random-effects model to pool results across studies and Peto one-step odds ratio (OR) for event rates below 1 %. Both-armed zero-event studies were excluded from the meta-analyses. We used the Grading of Recommendations Assessment, Development, and Evaluation system to evaluate the certainty of evidence.Results: Ninety-two RCTs were included. We found no significant difference between CQ/HCQ and control (placebo or non-CQ/HCQ) in the frequency of SAEs (OR: 0.98, 95 % confidence interval [CI]: 0.71–1.36, 25 trials, 11,605 participants, moderate certainty of evidence). No clear relationship was observed between CQ/HCQ and retinopathy (OR: 1,63, 95 % CI: -0.4–6.57, 5 trials, 344 participants, very low certainty of evidence). There was a low certainty of evidence of the effect of CQ/HCQ versus control on cardiac complications (Relative risk: 1.48, 95 % CI: 1.1–1.98, 8 trials, 5,970 participants).Conclusions: CQ and HCQ might be safe, with low frequency of SAEs on malarial and non-malarial conditions. No clear effect of their use on the incidence of retinopathy and cardiac complications was observed.The protocol for this systematic review was registered with PROSPERO (registration number: CRD42020177818)

Abstract Background The novel anti-malarial cipargamin (KAE609) has potent, rapid activity against Plasmodium falciparum. Transient asymptomatic liver function test elevations were previously observed in cipargamin-treated subjects in two trials: one in malaria patients in Asia and one in volunteers with experimentally induced malaria. In this study, the hepatic safety of cipargamin given as single doses of 10 to 150 mg and 10 to 50 mg once daily for 3 days was assessed. Efficacy results, frequency of treatment-emerging mutations in the atp4 gene and pharmacokinetics have been published elsewhere. Further, the R561H mutation in the k13 gene, which confers artemisinin-resistance, was associated with delayed parasite clearance following treatment with artemether–lumefantrine in Rwanda in this study. This was also the first study with cipargamin to be conducted in patients in sub-Saharan Africa. Methods This was a Phase II, multicentre, randomized, open-label, dose-escalation trial in adults with uncomplicated falciparum malaria in five sub-Saharan countries, using artemether–lumefantrine as control. The primary endpoint was ≥ 2 Common Terminology Criteria for Adverse Events (CTCAE) Grade increase from baseline in alanine aminotransferase (ALT) or aspartate transaminase (AST) during the 4-week trial. Results Overall, 2/135 patients treated with cipargamin had ≥ 2 CTCAE Grade increases from baseline in ALT or AST compared to 2/51 artemether–lumefantrine patients, with no significant difference between any cipargamin treatment group and the control group. Cipargamin exposure was comparable to or higher than those in previous studies. Hepatic adverse events and general safety and tolerability were similar for all cipargamin doses and artemether–lumefantrine. Cipargamin was well tolerated with no safety concerns. Conclusions This active-controlled, dose escalation study was a detailed assessment of the hepatic safety of cipargamin, across a wide range of doses, in patients with uncomplicated falciparum malaria. Comparison with previous cipargamin trials requires caution as no clear conclusion can be drawn as to whether hepatic safety and potential immunity to malaria would differ with ethnicity, patient age and or geography. Previous concerns regarding hepatic safety may have been confounded by factors including malaria itself, whether natural or experimental infection, and should not limit the further development of cipargamin.

Abstract Background Acupuncture for post-stroke depression (PSD) has been evolving, but uncertainty remains. To assess the existing evidence from randomized clinical trials (RCTs) of acupuncture for PSD, we sought to draw conclusions by synthesizing RCTs. Methods An exhaustive literature search was conducted in seven electronic databases from their inception dates to April 19, 2020, to identify systematic reviews (SRs) and meta-analyses (MAs) on this topic. The primary RCTs included in the SRs/MAs were identified. We also conducted a supplementary search for RCTs published from January 1, 2015, to May 12, 2020. Two reviewers extracted data separately and pooled data using RevMan 5.3 software. The quality of evidence was critically appraised with the Grades of Recommendation, Assessment, Development and Evaluation (GRADE) system. Results A total of 17 RCTs involving 1402 patients were included. Meta-analysis showed that participants who received a combination of acupuncture and conventional treatments exhibited significantly lower scores on the HAM-D17, HAM-D24 and HAM-D (MD, − 5.08 [95% CI, − 6.48 to − 3.67], I2 = 0%), (MD, − 9.72 [95% CI, − 14.54 to − 4.91], I2 = 65%) and (MD, − 2.72 [95% CI, − 3.61 to − 1.82], respectively) than those who received conventional treatment. However, there was no significant difference in acupuncture versus antidepressants in terms of the 17-item, 24-item and HAM-D scales (MD, − 0.43 [95% CI, − 1.61 to 0.75], I2 = 51%), (MD, − 3.09 [95% CI, − 10.81 to 4.63], I2 = 90%) and (MD, − 1.55 [95% CI, − 4.36 to 1.26], I2 = 95%, respectively). For adverse events, acupuncture was associated with fewer adverse events than antidepressants (RR, 0.16 [95% CI, 0.07 to 0.39], I2 = 35%), but there was no significant difference in the occurrence of adverse events between the combination of acupuncture and conventional treatments versus conventional treatments (RR, 0.63 [95% CI, 0.21 to 1.83], I2 = 38%). The quality of evidence was low to very low due to the substantial heterogeneity among the included studies. Conclusions The current review indicates that acupuncture has greater effect on PSD and better safety profile than antidepressants, but high-quality evidence evaluating acupuncture for PSD is still needed.

Background:The TNF-α inhibitor adalimumab is a biological disease modifying anti-rheumatic drug (bDMARD) that has been used in different rheumatic diseases with a resistant course. ABP-501 is a biosimilar product (BP) of adalimumab, recently approved by the FDA and EMA. To our knowledge, there is no study assess the efficacy and safety of these two molecules on pediatric patients.Objectives:We aimed to compare the efficacy and safety of the original and biosimilar adalimumab (ABP-501) molecules in childhood rheumatic diseases.Methods:This non-interventional, retrospective, single-centre analysis carried out in Umraniye Training and Resrach Hospital, Pediatric Rheumatology Clinic, Istanbul, Turkey. The study group consisted of patients who were followed due to chronic rheumatic disease between January 1, 2016 and June 1, 2020, and received reference or biosimilar adalimumab therapy for at least three months. Demographic and clinical data of patients were collected at baseline, 3rd, 6th, and 12th months of treatment. Disease activity assessment was made with JADAS-27 in JIA patients, with SUN criteria in uveitis patients, and with Behçet’s Disease Activity Index in BD patients. Efficacy and safety of treatments were compared between reference and biosimilar adalimumab groups.Results:A total of 89 patients (65 with original and 24 with biosimilar molecule) treated with adalimumab, were included in the study. There were 45 female and 44 male in the study, and the median age at the initiation of the adalimumab was 166 months (min-max: 36-231). Of the 89 patients evaluated, the primary diagnoses of 62 were juvenile idiopathic arthritis, 13 were idiopathic uveitis, eight were Behçet’s disease, three were Blau syndrome, two were chronic recurrent multifocal osteomyelitis and one was Vogt-Koyanagi-Harada syndrome. 63 of the patients were biologic-naïve, and 13 were switched from etanercept, 11 from infliximab, and two from other bDMARDs. The median exposure time of adalimumab was 16 months (min-max:3-70) in RP and 14.5 months (min-max: 3-23) in BP. All patients had active disease before treatment. In the group treated with RP, inactive disease was achieved in 60%, 76.6% and 87.2% of the patients at the 3rd, 6th and 12th months, respectively. Also, inactive disease was achieved in 62.5%, 78.2% and 78.2% of the patients at the 3rd, 6th and 12th months in the group treated with BP, respectively. There was no statistically significant difference in efficacy between the groups at the 3rd, 6th and 12th months (p=0.83, 0.07 and 0.32). Serious adverse events were seen in one patient in each groups (lymphoma in RP group, tuberculous meningitis in BP group). Non-serious adverse events were observed in eight patients (12.3%) in the RP group and in two patients (8.3%) in the BP group, without statistically significant difference between groups (p=0.86).Conclusion:No significant difference was observed between the biosimilar adalimumab ABP-501 and RP adalimumab in terms of efficacy and safety.References:[1]Renton, William D et al.

Aims: To assess the impact of cytochrome P450 (CYP) 2C19 polymorphisms on the clinical efficacy and safety of voriconazole. Methods: We systematically searched PubMed, EMBASE, CENTRAL, ClinicalTrials.gov, and three Chinese databases from their inception to March 18, 2021 using a predefined search algorithm to identify relevant studies. Studies that reported voriconazole-treated patients and information on CYP2C19 polymorphisms were included. The efficacy outcome was success rate. The safety outcomes included overall adverse events, hepatotoxicity and neurotoxicity. Results: A total of 20 studies were included. Intermediate metabolizers (IMs) and Poor metabolizers (PMs) were associated with increased success rates compared with normal metabolizers (NMs) (risk ratio (RR): 1.18, 95% confidence interval (CI): 1.03~1.34, I2=0%, p=0.02; RR: 1.28, 95%CI: 1.06~1.54, I2=0%, p=0.01). PMs were at increased risk of overall adverse events in comparison with NMs and IMs (RR: 2.18, 95%CI: 1.35~3.53, I2=0%, p=0.001; RR: 1.80, 95% CI: 1.23~2.64, I2=0%, p=0.003). PMs demonstrated a trend towards an increased incidence of hepatotoxicity when compared with NMs (RR: 1.60, 95%CI: 0.94~2.74, I2=27%, p=0.08), although there was no statistically significant difference. In addition, there was no significant association between CYP2C19 polymorphisms and neurotoxicity. Conclusions: IMs and PMs were at a significant higher success rate in comparison with NMs. PMs were significantly associated with an increased incidence of all adverse events compared with NMs and IMs. Researches are expected to further confirm these findings. Additionally, the relationship between hepatotoxicity and CYP2C19 polymorphisms deservers clinical attention.

Introduction: Pancreatic cancer is an aggressive tumor that had an estimated 57,600 new cases and 47,050 deaths in 2020 in the US alone. Recent studies have targeted tumor microenvironment (TME) for better delivery of systemic chemotherapy like PEGPH20, which degrades hyaluronic acid in the extracellular matrix (ECM). A meta-analysis of these Randomized controlled trials (RCTs) to test the efficacy of PEGPH20 was performed. Methods: A systematic search was performed using PubMed, Embase, and Cochrane library without language limitations from inception to July 30, 2020. A total of 59 articles was identified, and 3 RCTs were included in the final analysis. The primary outcome was progression-free survival (PFS), and secondary outcomes were overall survival (OS), deaths from adverse events, thromboembolic events, serious adverse events (SAE), and febrile neutropenia. Results: There was no statistically significant improvement in PFS (HR= 0.94; 95%CI (0.79, 1.11)) in the PEGPH20 group when compared to the standard treatment/placebo group. There was no significant difference among OS (HR= 0.99, 95%CI (0.83, 1.17), deaths from adverse events (RR=0.97; 95%CI (0.54, 1.73)), thromboembolic events (RR= 1.49; 95%CI (0.92, 2.44)), and febrile neutropenia (RR= 0.88; 95%CI (0.45, 1.72), however, there was statistically significant increase in SAE (RR = 1.59; 95%CI (1.01, 2.52) in the PEGPH20 group compared to the placebo group. Conclusion: This meta-analysis showed that PEGPH20 did not improve the PFS or OS. Moreover, there is an increased incidence of serious adverse events with the use of PEGPH20 compared to standard therapies.
