RESUMEN
Advances in the digitization of health systems and expedited regulatory approvals of innovative treatments have led to increased potential for the use of real-world data (RWD) to generate real-world evidence (RWE) to complement evidence from clinical trials. However, health technology assessment (HTA) bodies and payers have concerns about the ability to generate RWE of sufficient quality to be pivotal evidence of relative treatment effectiveness. Consequently, there is a growing need for HTA bodies and payers to develop guidance for the industry and other stakeholders about the use of RWD/RWE to support access, reimbursement, and pricing. We therefore sought to (i) understand barriers to the use of RWD/RWE by HTA bodies and payers; (ii) review potential solutions in the form of published guidance; and (iii) review findings with selected HTA/payer bodies. Four themes considered key to shaping the generation of robust RWE for HTA bodies and payers were identified as: (i) data (availability, governance, and quality); (ii) methodology (design and analytics); (iii) trust (transparency and reproducibility); and (iv) policy and partnerships. A range of guidance documents were found from trusted sources that could address these themes. These were discussed with HTA experts. This commentary summarizes the potential guidance solutions available to help resolve issues faced by HTA decision-makers in the adoption of RWD/RWE. It shows that there is alignment among stakeholders about the areas that need improvement in the development of RWE and that the key priority to move forward is better collaboration to make data usable for multiple purposes.

In the recent years, a number of targeted therapies have been approved for first-line treatment of patients with metastatic renal cell carcinoma. A systematic review was conducted to assess the clinical efficacy, safety and effect of all first-line treatments evaluated to date on health-related quality of life (HRQoL). A systematic search of Embase, Cochrane and MEDLINE databases was performed to identify randomized controlled trials (1980-2015) evaluating any targeted therapy/immunotherapy against placebo or any other targeted intervention/immunotherapy in treatment-naive patients with metastatic renal cell carcinoma. Conference proceedings from major cancer congresses (2007-2015) were handsearched. Sixteen randomized controlled trials were identified, mostly phase III. Overall, targeted therapies were associated with either improved [sunitinib, bevacizumab+interferon α (IFNα) and temsirolimus] or comparable (sorafenib) progression-free survival (PFS) versus IFNα monotherapy. Sunitinib demonstrated comparable PFS and overall survival to pazopanib, comparable PFS to sorafenib and shorter PFS compared with bevacizumab+IFNα (although no conclusions were made with regard to superiority/inferiority). Compared with sorafenib, tivozanib demonstrated a significantly longer PFS, and both tivozanib and axitinib demonstrated higher response rates. Nintedanib demonstrated comparable PFS and overall survival to sunitinib in a phase II trial. Temsirolimus, sunitinib and sorafenib treatment led to better HRQoL versus IFNα; pazopanib was associated with better HRQoL versus sunitinib. No direct meta-analyses or indirect treatment comparison analysis were undertaken because of noncomparability of the trials. In general, targeted therapies demonstrated favourable clinical efficacy and improved HRQoL compared with IFNα monotherapy. The newer therapies, tivozanib and axitinib (but not nintedanib), appeared to exhibit greater clinical benefit (response rate) than older tyrosine kinase inhibitors.

BACKGROUND: Fabry disease (FD) is a rare lysosomal storage disease associated with glycolipid accumulation that impacts multiple physiological systems. We conducted a systematic literature review (SLR) to characterize the humanistic (quality of life [QoL]) and economic burden of FD. METHODS: Searches were conducted in the Embase, MEDLINE®, and MEDLINE® In-Process databases from inception to January 19, 2022. Conference abstracts of specified congresses were manually searched. Additional searches were performed in the Cochrane and ProQuest databases for the humanistic SLR and the National Health Service Economic Evaluations Database for the economic SLR. Studies of patients with FD of any sex, race, and age, and published in the English language were included. There was no restriction on intervention or comparator. For the humanistic SLR, studies that reported utility data, database/registry-based studies, questionnaires/surveys, and cohort studies were included. For the economic SLR, studies reporting economic evaluations or assessing the cost of illness and resource use were included. RESULTS: Of the 1363 records identified in the humanistic search, 36 studies were included. The most commonly used QoL assessments were the 36-item Short-Form Health Survey (n = 16), EQ-5D questionnaire descriptive system or visual analog scale (n = 9), and the Brief Pain Inventory (n = 8). Reduced QoL was reported in patients with FD compared with healthy populations across multiple domains, including pain, physical functioning, and depressive symptoms. Multiple variables-including sex, age, disease severity, and treatment status-impacted QoL. Of the 711 records identified in the economic burden search, 18 studies were included. FD was associated with high cost and healthcare resource use. Contributors to the cost burden included enzyme replacement therapy, healthcare, and social care. In the seven studies that reported health utility values, lower utility scores were generally associated with more complications (including cardiac, renal, and cerebrovascular morbidities) and with classical disease in males. CONCLUSION: FD remains associated with a high cost and healthcare resource use burden, and reduced QoL compared with healthy populations. Integrating information from QoL and economic assessments may help to identify interventions that are likely to be of most value to patients with FD.

BACKGROUND: Current guidelines recommend anthracycline-based chemotherapy primarily with doxorubicin either as monotherapy or in combination with ifosfamide as the first-line treatment for most advanced STS subtypes. Therapeutic options after failure of doxorubicin and/or ifosfamide are limited. This study aimed to comprehensively review available data on the activity and safety of interventions in second- or later-line treatment of advanced STS. METHODS: Electronic literature databases (Embase®, MEDLINE®, MEDLINE® In-Process, Cochrane Central Register of Controlled Trials, and Cochrane Database of Systematic Reviews) were searched from 1980 to 01 March 2012 to identify randomised controlled trials (RCTs) and non-randomised studies (both prospective and retrospective) evaluating pharmacological interventions in patients with advanced STS pre-treated with anthracycline- and/or ifosfamide-based therapy. RESULTS: The review identified six RCTs (one phase III and five phase II trials) and 94 non-randomised studies. Based on the primary trial endpoints, RCTs demonstrated favourable efficacy for pazopanib over placebo (PFS: 4.6 months vs. 1.6 months), gemcitabine plus dacarbazine over dacarbazine monotherapy (3-month PFS rate: 54.2% vs. 35.2%), and trabectedin 3-weekly schedule over weekly schedule (TTP: 3.7 months vs. 2.3 months. The non-randomised studies demonstrated heterogeneity in efficacy and safety results. CONCLUSIONS: Across the RCTs, pazopanib over placebo, gemcitabine-dacarbazine over dacarbazine, and trabectedin 3-weekly over weekly regimen clearly demonstrated a PFS advantage in the second- and later-line treatment of advanced STS. With only one phase III trial in this setting, there is a clear need for additional comparative trials to better understand the risk: benefit ratios of available agents and combinations.

The objective of this study was to develop and characterize a novel dithranol-containing phospholipid microemulsion systems for enhanced skin permeation and retention. Based on the solubility of dithranol, the selected oils were isopropyl myristate (IPM) and tocopherol acetate (TA), and the surfactants were Tween 80 (T80) and Tween 20 (T20). The ratios of cosurfactants comprising of phospholipids and ethanol (1 : 10) and surfactant to co-surfactant (1 : 1 and 2.75 : 1) were fixed for the phase diagram construction. Selected microemulsions were evaluated for globule size, zeta potential, viscosity, refractive index, per cent transmittance, stability (freeze thaw and centrifugation), ex vivo skin permeation and retention. The microemulsion systems composed of IPM and T80 with mean particle diameter of 72.8 nm showed maximum skin permeation (82.23%), skin permeation flux (0.281 mg/cm²/h) along with skin retention (8.31%) vis-à-vis systems containing TA and T20. The results suggest that the developed novel lecithinized microemulsion systems have a promising potential for the improved topical delivery of dithranol.

OBJECTIVES: To evaluate the relative clinical efficacy, safety, and tolerability associated with two non-invasive patient-controlled analgesia (PCA) treatments, sufentanil sublingual tablet system (SSTS) and fentanyl iontophoretic patient-controlled transdermal system (PCTS). These two treatments have recently been approved in the EU for the management of acute moderate-to-severe post-operative pain in adult patients. METHODS: As no head-to-head trials comparing SSTS and PCTS currently exist, indirect treatment comparison (ITC) analyses were conducted to evaluate SSTS or PCTS versus intravenous (IV) morphine PCA. RESULTS: Five studies, four assessing PCTS and one assessing SSTS, were included in this analysis. SSTS had statistical or numerical advantages over PCTS for both patient global assessment (PGA) and healthcare professional global assessment (HPGA) outcomes at all time points investigated. SSTS was also associated with greater patient ease of use (weighted mean difference [WMD]: 0.13; 95% confidence interval [CI]: -0.02-0.28) and a higher patient satisfaction score (WMD: 0.31; 95% CI: 0.05-0.57; p = .019) compared with PCTS. In terms of tolerability, all-cause withdrawals from treatment were reported to be less likely with SSTS (risk ratio: 0.65; 95% CI: 0.42-1.02). No significant differences were observed between SSTS and PCTS in terms of safety and adverse events. CONCLUSIONS: In the absence of direct head-to-head data, the combination of promising phase III trial results compared to IV morphine PCA, a SLR comparison against other opioid treatments, and the results of this exploratory analysis present a strong rationale in support of SSTS as a key option for management of post-operative pain.

OBJECTIVE: To conduct a systematic literature review (SLR) and quantitative analysis to assess the comparative efficacy and safety of the sufentanil sublingual tablet system (SSTS) against other available patient controlled analgesia (PCA) options for post-operative analgesia. METHODS: An SLR was conducted for studies published between 2004 and 2016. Due to study heterogeneity, subgroup analyses were conducted controlling for differences in imputation methods for missing values, baseline pain severity, and type of surgery. Where sufficient data was available, a mixed treatment comparison (MTC) was performed. RESULTS: The MTC and subgroup analyses used 13 studies. In direct meta-analysis, there was a statistically significant difference in favor of SSTS compared with intravenous (IV) PCA (morphine) at 24 hours for the patient global assessment (PGA) scores of "good" or "excellent". For the Pain Intensity Score, there were numerical but not statistically significant differences in favor of the SSTS versus IV PCA (morphine) and the patient controlled transdermal system (PCTS) (fentanyl) in the MTC at 6 hours (standardized mean difference -0.27 [credible interval -2.78, 2.09] and -0.36 [-3.89, 3.03], respectively). The onset of pain relief was earlier with the SSTS versus IV PCA (morphine) as shown by the Pain Intensity Difference. Likewise, the onset was earlier compared with PCTS (fentanyl) where data was available. There was a significant difference in favor of SSTS compared with IV PCA (morphine) and with PCTS (fentanyl) for any adverse event, and numerical improvements for withdrawals due to adverse events. CONCLUSIONS: This meta-analysis shows that SSTS is an option for non-invasive management of moderate-to-severe post-operative pain which can be more effective, faster in onset and better tolerated than IV PCA (morphine) and PCTS (fentanyl).

OBJECTIVES: To assess the relative efficacy and tolerability of vortioxetine against different antidepressant monotherapies in patients with major depressive disorder (MDD) with inadequate response to selective serotonin reuptake inhibitor (SSRI) or serotonin-norepinephrine reuptake inhibitor (SNRI) therapy. METHODS: A systematic search was conducted for monotherapy studies in patients with MDD with inadequate response to first-line therapy. Treatments included SSRIs, SNRIs, and other antidepressants. Identified studies underwent a three-stage screening/data extraction process and critical appraisal. Adjusted indirect treatment comparisons (ITCs) on systematic literature review outputs were made using Bucher's method, comparing remission rates and withdrawal rates due to adverse events (AEs). RESULTS: Of 27 studies meeting the inclusion criteria, a few studies were of high quality according to the National Institute of Health and Care Excellence checklist. Three studies contributed to an evidence network for quantitative assessment comparing vortioxetine with agomelatine, sertraline, venlafaxine XR, and bupropion SR. Vortioxetine had a statistically significantly higher remission rate than agomelatine (risk difference [RD]: -11.0% [95% CI: -19.4; -2.6]), and numerically higher remission rates than sertraline (RD: -14.4% [95% CI: -29.9; 1.1]), venlafaxine (RD: -7.20% [95% CI: -24.3; 9.9]), and bupropion (RD: -10.70% [95% CI: -27.8; 6.4]). Withdrawal rates due to AEs were statistically significantly lower for vortioxetine than sertraline (RD: 12.1% [95% CI: 3.1; 21.1]), venlafaxine XR (RD: 12.3% [95% CI: 0.8; 23.8]), and bupropion SR (RD: 18.3% [95% CI: 6.4; 30.1]). CONCLUSIONS: The current systematic literature review found a few high quality switch studies assessing monotherapies in patients with MDD with inadequate response to SSRI/SNRIs. ITCs indicated that switching to vortioxetine leads to numerically higher remission rates compared with other antidepressants. Vortioxetine is a well tolerated treatment, showing statistically lower withdrawal rates due to AEs compared with other antidepressants. Vortioxetine is a relevant therapeutic alternative in patients experiencing inadequate response to prior SSRI or SNRI therapy.
