- Abstract
43 p., ill., Les tests pharmacogénétiques visent à déterminer comment l’ADN des patients peut influencer l’effet qu’aura, chez eux, un traitement pharmacologique donné. Grâce à cette information, il est possible d’affiner le choix du médicament ou de son dosage. À la demande de l’INAMI, le Centre Fédéral d’Expertise des Soins de Santé (KCE) s’est penché sur l’utilisation de ces tests dans notre pays. Conclusion ? Actuellement, les conditions préalables à l’utilisation efficace de la pharmacogénétique ne sont pas suffisamment réunies, et il n’existe pas toujours de consensus quant à l’utilité clinique de certains tests. Une approche plus harmonisée et scientifiquement étayée de l’utilisation de ces tests nécessite notamment un déploiement plus important de l’expertise en pharmacologie clinique, pour conseiller les médecins et leurs patients, et pour élaborer des directives nationales quant à l’utilisation des tests pharmacogénétiques., PRÉFACE 1 -- SYNTHÈSE 2 -- 1.

- Abstract
42 p., ill., Een farmacogenetische test gaat na hoe het DNA van een patiënt de werking van een bepaald geneesmiddel kan beïnvloeden. Op die manier kan een geneesmiddel of de dosering ervan nauwkeuriger worden afgestemd. Op vraag van het RIZIV nam het Federaal Kenniscentrum voor de Gezondheidszorg (KCE) het gebruik van deze tests in ons land onder de loep. Het kwam tot de conclusie dat de randvoorwaarden voor een efficiënt gebruik van farmacogenetica momenteel niet voldoende aanwezig zijn, en dat er geen consensus bestaat over het klinisch nut van sommige farmacogenetische tests. Voor een meer geharmoniseerd en wetenschappelijk onderbouwd beleid rond deze testen is er o.a. meer inzet van expertise in klinische farmacologie nodig, om advies te verlenen aan artsen en patiënten, en om nationale richtlijnen voor het gebruik van farmacogenetische tests te ontwikkelen., VOORWOORD 1 -- SYNTHESE 2 -- 1.

Background: Although metastatic cutaneous melanoma is associated with an unfavorable prognosis, innovative therapies including immunomodulating agents and targeted therapies have shown survival benefits in clinical trials. We assessed the impact of the introduction of innovative drugs into clinical practice on the survival of patients with metastatic cutaneous melanoma during the period 2004–2017, in Belgium. The evolution of associated expenses was also analyzed. Methods: This is a retrospective population‐based study using data from the national Belgian Cancer Registry, compulsory health insurance, and administrative survival data. The immunomodulating drugs were ipilimumab, nivolumab and pembrolizumab, while targeted therapies included vemurafenib, dabrafenib and trametinib. Results: We did not identify a trend for improvement over time. Median survival (years) was 1.5 (95% CI: 1.1–1.8) in 2004–2008, 1.1 (95% CI: 0.8–1.5) in 2009–2013, and 1.6 (95% CI: 1.3–2.4) in 2014–2017, respectively. In contrast, survival improved in those with unknown primary tumor localization. In this group, median survival time was 2.0 (95% CI: 1.4–2.9) in the most recent period, while it was 1.1 (95% CI: 0.7–1.3) in 2009–2013, and 0.9 (95% CI: 0.6–1.2) in 2004–2008. The uptake of innovative drugs remained modest, with no drug being used by more than 30% of patients. Yearly expenditure was almost non‐existent, and gradually increased, reaching several million euros in 2014–2017. Conclusion: Patients with metastatic cutaneous melanoma who were diagnosed between 2004 and 2017 showed no apparent improvement in survival. In contrast, increased survival was observed in the subgroup of patients with unknown primary tumor localization. [ABSTRACT FROM AUTHOR]

- Abstract
The emergence of the precision medicine paradigm in oncology has led to increasing interest in the integration of real-world data (RWD) into cancer clinical research. As sources of real-world evidence (RWE), such data could potentially help address the uncertainties that surround the adoption of novel anticancer therapies into the clinic following their investigation in clinical trials. At present, RWE-generating studies which investigate antitumour interventions seem to primarily focus on collecting and analysing observational RWD, typically forgoing the use of randomisation despite its methodological benefits. This is appropriate in situations where randomised controlled trials (RCTs) are not feasible and non-randomised RWD analyses can offer valuable insights. Nevertheless, depending on how they are designed, RCTs have the potential to produce strong and actionable RWE themselves. The choice of which methodology to employ for RWD studies should be guided by the nature of the research question they are intended to answer. Here, we attempt to define some of the questions that do not necessarily require the conduct of RCTs. Moreover, we outline the strategy of the European Organisation for Research and Treatment of Cancer (EORTC) to contribute to the generation of robust and high-quality RWE by prioritising the execution of pragmatic trials and studies set up according to the trials-within-cohorts approach. If treatment allocation cannot be left up to random chance due to practical or ethical concerns, the EORTC will consider undertaking observational RWD research based on the target trial principle. New EORTC-sponsored RCTs may also feature concurrent prospective cohorts composed of off-trial patients.

Background Infections with SARS-CoV-2 continue to cause significant morbidity and mortality. Interleukin (IL)-1 and IL-6 blockade have been proposed as therapeutic strategies in COVID-19, but study outcomes have been conflicting. We sought to study whether blockade of the IL-6 or IL-1 pathway shortened the time to clinical improvement in patients with COVID-19, hypoxic respiratory failure, and signs of systemic cytokine release syndrome. Methods We did a prospective, multicentre, open-label, randomised, controlled trial, in hospitalised patients with COVID-19, hypoxia, and signs of a cytokine release syndrome across 16 hospitals in Belgium. Eligible patients had a proven diagnosis of COVID-19 with symptoms between 6 and 16 days, a ratio of the partial pressure of oxygen to the fraction of inspired oxygen (PaO2:FiO(2)) of less than 350 mm Hg on room air or less than 280 mm Hg on supplemental oxygen, and signs of a cytokine release syndrome in their serum (either a single ferritin measurement of more than 2000 mu g/L and immediately requiring high flow oxygen or mechanical ventilation, or a ferritin concentration of more than 1000 mu g/L, which had been increasing over the previous 24 h, or lyrnphopenia below 800/mL with two of the following criteria: an increasing ferritin concentration of more than 700 mu g/L, an increasing lactate dehydrogenase concentration of more than 300 international units per L, an increasing C-reactive protein concentration of more than 70 mg/L, or an increasing D-dimers concentration of more than 1000 ng/mL). The COV-AID trial has a 2 x 2 factorial design to evaluate IL-1 blockade versus no IL-1 blockade and IL-6 blockade versus no IL-6 blockade. Patients were randomly assigned by means of permuted block randomisation with varying block size and stratification by centre. In a first randomisation, patients were assigned to receive subcutaneous anakinra once daily (100 mg) for 28 days or until discharge, or to receive no IL-1 blockade (1:2). In a second randomisation step, patients were allocated to receive a single dose of siltuximab (11 mg/kg) intravenously, or a single dose of tocilizumab (8 mg/kg) intravenously, or to receive no IL-6 blockade (1:1:1). The primary outcome was the time to clinical improvement, defined as time from randomisation to an increase of at least two points on a 6-category ordinal scale or to discharge from hospital alive. The primary and supportive efficacy endpoints were assessed in the intention-to-treat population. Safety was assessed in the safety population. This study is registered online with ClinicalTrials.gov (NCT04330638) and EudraCT (2020-001500-41) and is complete. Findings Between April 4, and Dec 6,2020,342 patients were randomly assigned to IL-1 blockade n=112) or no IL-1 blockade (n=230) and simultaneously randomly assigned to IL-6 blockade (n=227; 114 for tocilizumab and 113 for siltuximab) or no IL-6 blockade (n=115). Most patients were male (265 [77%] of 342), median age was 65 years (IQR 54-73), and median Systematic Organ Failure Assessment (SOFA) score at randomisation was 3 (2-4). All 342 patients were included in the primary intention-to-treat analysis. The estimated median time to clinical improvement was 12 days (95% CI 10-16) in the IL-1 blockade group versus 12 days (10-15) in the no IL-1 blockade group (hazard ratio [HR] 0.94 [95% CI 0.73-1.21]). For the IL-6 blockade group, the estimated median time to clinical improvement was 11 days (95% CI 10-16) versus 12 days (11-16) in the no IL-6 blockade group (HR 1.00[0-78-1-29]). 55 patients died during the study, but no evidence for differences in mortality between treatment groups was found. The incidence of serious adverse events and serious infections was similar across study groups. Interpretation Drugs targeting IL-1 or IL-6 did not shorten the time to clinical improvement in this sample of patients with COVID-19, hypoxic respiratory failure, low SOFA score, and low baseline mortality risk.
