Frontiers in Neurology 2022Systematic review.
STUDY DESIGN
Systematic review.
OBJECTIVE
To provide current evidence on the efficacy of 4-aminopyridine (4-AP) to bring about functional improvement in individuals with chronic traumatic spinal cord injury (SCI).
METHODS
The Medline (PubMed), Web of Science and SCOPUS databases were systematically searched for relevant articles on the efficacy of 4-AP to treat SCI, from the dates such articles were first published until May 2022. Full-text versions of all the articles selected were examined independently by two reviewers. Methodological quality was rated using the Modified Jadad Scale, and risk of bias was assessed with the RoB-2 test. Data extracted included human models/types, PRISMA assessment protocols, and the results of each study. Descriptive syntheses are provided.
RESULTS
In total, 28 articles were initially identified, 10 of which were included after screening. Most of the studies reviewed reported some degree of patient improvement in one or more of the following parameters: motor, sensitivity and sexual function, sphincter control, spasticity, ability to function independently, quality of life, central motor conduction, pain, and pulmonary function.
CONCLUSIONS
This review confirms the efficacy of 4-AP in improving several conditions resulting from SCI but further research on this topic is warranted. Additional randomized clinical trials with 4-AP involving larger sample sizes are needed, as are consistent outcome measures in order to obtain adequate data for analysis with a view to enhance treatment benefits.

Review
OBJECTIVE
This article reviews clinical trials to assess the efficacy, safety, and clinical application of once-daily roflumilast 0.3% cream for the treatment of plaque psoriasis.
DATA SOURCES
A systematic review of the literature was performed using the terms OR OR in MEDLINE (PubMed) and EMBASE databases between January 2012 and October 2022. Bibliographies and the ClinicalTrials.gov website were also searched to identify further studies.
STUDY SELECTION AND DATA EXTRACTION
Studies written in English and relevant to pharmacology, clinical trials, and safety were considered for inclusion.
DATA SYNTHESIS
In two 8-week phase III clinical trials, disease severity as assessed by a score of "clear" or "almost clear" and a 2-point improvement on Investigator Global Assessment (IGA) was 42.4% and 37.5% at week 8 in DERMIS-1 and DERMIS-2, respectively, compared to 6.1% and 6.9% in the control groups. In the 52-week phase III trial, treatment success rates for plaque psoriasis and intertriginous psoriasis were similar to the 8-week data with 45% of patients in the treatment group were evaluated as an IGA of "clear" or "almost clear" at week 52.
RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE IN COMPARISON TO EXISTING DRUGS
Roflumilast is a new US Food and Drug Administration (FDA)-approved topical phosphodiesterase inhibitor that shows promise for the treatment of mild-severe plaque psoriasis. It is an effective and safe topical nonsteroidal alternative to currently available topical corticosteroids, but there are currently no comparative studies with other psoriasis treatments.
CONCLUSION
Roflumilast is effective and safe for the treatment of plaque psoriasis and intertriginous psoriasis. Future trials should compare its efficacy and tolerability with that of the older, clinically established topical corticosteroids. Prohibitive factors may include limited patient adherence to topical treatments and cost.

Review
BACKGROUND
Evaluation of health-related quality of life (HR-QoL) among cancer patients has gained an increasing importance and is now a key determinant of anticancer treatments' value. HR-QoL has been assessed in trials testing cyclin-dependent kinase 4/6 inhibitors (CDK4/6i) in breast cancer (BC), using various questionnaires at different timepoints. HR-QoL reports from BC patients treated with CDK4/6i in the real-world setting are also available.
METHODS
We systematically reviewed the literature, searching for full-length articles, and selected conference abstracts reporting data on HR-QoL in BC patients at any stage and of any molecular subtype treated with abemaciclib, palbociclib or ribociclib.
RESULTS
A total of 533 full-length articles and 143 abstracts were retrieved. After screening for eligibility, 38 records were included (31 clinical trials; 7 real-world reports). Assessment methods were heterogeneous across studies in terms of questionnaires, evaluation timepoints and endpoints. Overall, adding CDK4/6i to endocrine therapy did not worsen patients' HR-QoL, with a positive trend towards pain improvement. Gastrointestinal scores (diarrhea, nausea and appetite loss) statistically favored the control arm among metastatic BC patients receiving abemaciclib, whereas they were superimposable in the early setting. The combination of palbociclib and endocrine therapy showed similar HR-QoL outcomes compared with endocrine therapy alone, but determined better scores compared with chemotherapy. HR-QoL was specifically assessed in premenopausal patients treated with ribociclib, showing similar scores compared with postmenopausal patients.
CONCLUSIONS
Despite methodological heterogeneity does not allow a proper comparison, HR-QoL was generally maintained with CDK4/6i. However, differences between abemaciclib, palbociclib and ribociclib exist and mainly rely on the distinct safety profiles of the compounds. These differences should be acknowledged and taken into account in the clinical practice.

Review
BACKGROUND
The Creutzfeldt-Jakob disease (CJD) is a spongiform encephalopathy that manifests as a rapidly progressive dementia syndrome. Currently, CJD has no cure, and many patients die within the first year, but some drugs are being studied as options for managing this condition.
OBJECTIVE
To evaluate the effectiveness of pharmacological treatments offered to patients with CJD as a means to increase survival and reduce cognitive deterioration.
METHODS
A systematic review of the literature was performed using 4 independent reviewers and 1 extra reviewer to resolve possible divergences in the search and analysis of papers indexed in MedLINE (PubMed), SciELO and Lilacs databases. The Medical Subject Heading (MeSH) terms used were: , , , , , , , and , with the Boolean operators and . This search included controlled clinical trials, uncontrolled clinical trials, and case series published from the year 2000 onwards, in the English language.
RESULTS
A total of 85 papers were found using the descriptors used. At the end of the selection analyses, 9 articles remained, which were analyzed fully and individually.
CONCLUSIONS
None of the drugs evaluated proved significantly effective in increasing survival in patients with CJD. Flupirtine appears to have a beneficial effect in reducing cognitive deterioration in patients with CJD. However, additional studies are needed to establish better evidence and therapeutic options for the management of patients with CJD.

Meta-Analysis
OBJECTIVES
To systematically evaluate the efficacy and safety of anaplastic lymphoma kinase (ALK) inhibitors in ALK-rearranged positive non-small cell lung cancer (NSCLC) with brain metastases, and update the overall survival (OS) outcomes of the second-generation and third-generation ALK (ALK-2G/3G) inhibitors versus first-generation (ALK-1G) inhibitors.
DESIGN
The study is in accordance with the Preferred Reporting Items for Systematic Review and Meta-analysis guidelines. Randomised controlled trials (RCTs) published up to 3 November 2021 were retrieved from PubMed, EMBASE, Cochrane Library and ClinicalTrials.gov.
SETTING
RCTs from any country and healthcare setting.
PARTICIPANTS
Patients with advanced ALK-positive NSCLC with or without brain metastases.
INTERVENTIONS AND COMPARISONS
The interventions were ALK-2G/3G; the control arm was ALK-1G or crizotinib.
PRIMARY AND SECONDARY OUTCOME MEASURES
Primary outcomes included median progression-free survival and median OS. Secondary outcomes included systemic objective response rate, intracranial response rate and rate of grade ≥3 adverse events (AEs).
RESULTS
A total of 12 RCTs involving 3156 patients were analysed. Compared with ALK-1G (crizotinib), ALK-2G (alectinib, brigatinib, ceritinib and ensartinib) significantly improved the OS (HR: 0.72, 95% CI: 0.57 to 0.90, p=0.004) and intracranial response of patients with any brain metastases, especially with measurable (diameter ≥10 mm) brain metastases. Network meta-analysis demonstrated that ALK-3G (lorlatinib) had superior efficacy for patients with brain lesions, but performed a distinct side-effect profile. Moreover, alectinib showed superior efficacy and lower toxicity in ALK-positive NSCLC.
CONCLUSION
Treatment with ALK-2G inhibitors significantly improved OS compared with crizotinib, and alectinib has less severe AEs than any other ALK inhibitors with moderate-high efficacy. The limited OS follow-up and inadequate sample sizes might contribute to having no statistically significant difference in OS of lorlatinib versus crizotinib. More high-quality and longer follow-up RCTs are warranted to prove our findings.

Meta-Analysis Review
Anaplastic lymphoma kinase (ALK) inhibitors are commonly used for patients harboring ALK-positive non-small cell lung cancer (NSCLC). This meta-analysis was conducted to evaluate the toxicity profile of ALK inhibitors. Pubmed, Web of Science, Embase, and the Cochrane Central Register of Controlled Trials databases were systematically searched for clinical trials conducted in advanced NSCLC treated with ALK inhibitors. The incidences of pooled adverse events (AEs) were conducted using the random effects model. We included 30 studies in the meta-analysis. Almost all patients receiving ALK inhibitor monotherapy occurred at least one AE. The pooled incidences of grade ≥ 3 AEs were 71.3% for ceritinib 750 mg, 44.6% for crizotinib, 37.4% for alectinib, and 35.3% for ensartinib. Only one study each reported the incidence of grade ≥ 3 AEs for brgatinib (72.8%), lorlatinib (72.4%), and ceritinib 450 mg (64.8%), respectively. The rates of dose reduction due to AEs ranking from high to low were ceritinib 750 mg, brigatinib, ceritinib 450 mg, lorlatinib, crizotinib, ensartinib, and alectinib. The rates of treatment discontinuation due to AEs were low, ranging from 3.8% to 10.5%. Gastrointestinal AEs were most common for ceritinib 750 mg. Hepatic transaminases elevation was mostly observed in ceritinib and brigatinib. Rash frequently occurred for ensartinib. Lorlatinib had a high incidence of hypertriglyceridemia and hypercholesterolemia, which were rarely reported in other ALK inhibitors. The incidences of grade ≥ 3 AEs for individual ALK inhibitor were moderately high yet manageable. Different toxicity spectrums were found in each ALK inhibitor.

Cyclin-dependent kinase 4 and 6 (CDK4/6) inhibitors have revolutionized the treatment of hormone-positive metastatic breast cancers (mBCs). They are currently established as standard therapies in combination with endocrine therapy as first- and second-line systemic treatment options for both endocrine-sensitive and endocrine-resistant mBC populations. In the first-line metastatic setting, the median progression-free survival for the three currently approved CDK4/6 inhibitors, palbociclib, ribociclib, and abemaciclib, with aromatase inhibitors is greater than 2 years (palbociclib 27.6 months; ribociclib 25.3 months; and abemaciclib 28.18 months). Although CDK4/6 inhibitors have significant clinical benefits and enable physicians to delay starting chemotherapy, they are expensive and can be associated with drug toxicities. Here, we have performed a systemic review of the reported molecular markers predictive of drug response including intrinsic and acquired resistance for CDK4/6 inhibition in mBC. The rapidly emerging molecular landscape is captured through next-generation sequencing of breast cancers (DNA with or without RNA), liquid biopsies (circulating tumor DNA), and protein analyses. Individual molecular candidates with robust and reliable evidence are discussed in more depth.

Meta-Analysis
BACKGROUND
Crizotinib and alectinib are the 2 most commonly used anaplastic lymphoma kinase (ALK) inhibitors for ALK-positive non-small cell lung cancer (NSCLC). We compared their antitumor efficacies and adverse effects based on a pooled analysis of the ALEX, ALESIA, and J-ALEX clinical trials.
METHODS
Seven databases were searched for eligible articles. The primary endpoints included overall survival (OS), progression-free survival (PFS), central nervous system (CNS)-PFS, drug responses, and adverse effects (AEs).
RESULTS
Seven articles on 3 randomized controlled clinical trials (ALEX, ALESIA, and J-ALEX) that included 697 patients were included. Compared with crizotinib, alectinib exhibited superior efficacy in PFS (HR [hazard ratio]: 0.35 [0.25-0.49], p < 0.00001), OS (HR: 0.66 [0.47-0.92], p = 0.02), CNS-PFS (HR: 0.17 [0.11-0.24], p < 0.00001), duration of response (HR: 0.31 [0.23-0.42], p < 0.00001), objective response rate (risk ratio [RR]: 0.87 [0.80-0.94], p = 0.0003), partial response (RR: 0.88 [0.81-0.96], p = 0.004), and grade 3-5 AEs (RR: 1.43 [1.09-1.87], p = 0.009). Additionally, compared with crizotinib, alectinib exhibited a survival advantage that increased with its prolongation of survival time. The disease control rate, complete response, and total AEs were comparable between the 2 groups. The crizotinib group reported higher rates of constipation, nausea, diarrhea, vomiting, peripheral edema, dysgeusia, visual impairment, and levels of alanine aminotransferase and aspartate aminotransferase as well as greater decreases in appetite and neutrophil count.
CONCLUSIONS
In both antitumor efficacy and safety, alectinib appears to be superior to crizotinib for the treatment of ALK-positive NSCLC.

Comparative Study Meta-Analysis
BACKGROUND
Whereas there are many pharmacological interventions prescribed for patients with advanced anaplastic lymphoma kinase (ALK)- rearranged non-small cell lung cancer (NSCLC), comparative data between novel generation ALK-tyrosine kinase inhibitors (TKIs) remain scant. Here, we indirectly compared the efficacy and safety of first-line systemic therapeutic options used for the treatment of ALK-rearranged NSCLC.
METHODS
We included all phase 2 and 3 randomised controlled trials (RCTs) comparing any two or three treatment options. Eligible studies reported at least one of the following outcomes: progression free survival (PFS), overall survival (OS), objective response rate (ORR), or adverse events of grade 3 or higher (Grade ≥ 3 AEs). Subgroup analysis was conducted according to central nervous system (CNS) metastases.
RESULTS
A total of 9 RCTs consisting of 2484 patients with 8 treatment options were included in the systematic review. Our analysis showed that alectinib (300 mg and 600 mg), brigatinib, lorlatinib and ensartinib yielded the most favorable PFS. Whereas there was no significant OS or ORR difference among the ALK-TKIs. According to Bayesian ranking profiles, lorlatinib, alectinib 600 mg and alectinib 300 mg had the best PFS (63.7%), OS (35.9%) and ORR (37%), respectively. On the other hand, ceritinib showed the highest rate of severe adverse events (60%).
CONCLUSION
Our analysis indicated that alectinib and lorlatinib might be associated with the best therapeutic efficacy in first-line treatment for major population of advanced NSCLC patients with ALK-rearrangement. However, since there is little comparative evidence on the treatment options, there is need for relative trials to fully determine the best treatment options as well as the rapidly evolving treatment landscape.

Meta-Analysis
INTRODUCTION
Anaplastic Lymphoma Kinase (ALK) inhibitors have revolutionized the treatment of advanced ALK-positive non-small cell lung cancer (NSCLC), improving progression-free survival. Bradycardia is a potential adverse effect of these agents. We aimed to determine the risk of bradycardia associated with ALK inhibitors in patients with advanced NSCLC.
MATERIALS AND METHODS
We conducted a systematic search of MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, National clinical trial registry, and Web of Science Core Collection. We included all randomized controlled trials in which an ALK-inhibitor was compared with another ALK-inhibitor or standard chemotherapy. Meta-analyses were conducted to evaluate the pooled incidence rates of bradycardia and dizziness using fixed effect models.
RESULTS
The pooled incidence of bradycardia among 1737 individuals prescribed ALK inhibitors was 8% during a mean follow-up of 1.26 years. Crizotinib led to more bradycardia than standard chemotherapy (relative risk, RR 24.68, 95% CI 7.11-85.), while no difference was seen between crizotinib and alectinib (RR 1.12, 95% CI 0.79-1.59). The next-generation ALK inhibitors alectinib, brigatinib and lorlatinib combined resulted in a similar rate of bradycardia when compared to crizotinib (RR 0.77, 95% CI 0.57-1.04). All ALK inhibitors (as an aggregate) caused more dizziness (as a potential symptom of bradycardia) than standard chemotherapy (RR 1.88, 95% CI 1.44-2.44).
CONCLUSION
Crizotinib for the treatment of NSCLC is associated with a higher risk for bradycardia compared to standard chemotherapy. There is no evidence of a difference in bradycardia risk between crizotinib and newer ALK inhibitors.
