Penetration rates of new pharmaceutical products in Europe: A comparative study of several classes recently launched in type-2 diabetes.

BACKGROUND: Different countries have their own systems for evaluating new medicines, and they make decisions as to when and how each new medicine is adopted. PURPOSE: To compare the rate of uptake of new diabetes medicines (dipeptidyl peptidase-4 inhibitors [DPP-4Is], glucagon-like peptide-1 receptor agonists [GLP1-RAs], and sodium-glucose co-transporter-2 inhibitors [SGLT2Is]) in the five most populated European countries. METHODS: The monthly volume of sales of antidiabetic drugs was extracted for each country from the IQVIA™ MIDAS® database for the period 2007 to 2016 and the defined daily doses (DDDs) were calculated. For each new drug, market shares were expressed as a percentage of the total market of non-insulin antidiabetic agents. RESULTS: Sharp differences were observed between the countries. Overall, the highest and fastest rates of uptake were seen for Germany and Spain, compared to lower rates for the UK and Italy. This was especially marked for DPP-4Is, where the market share reached over 30% of non-insulin antidiabetic drugs in Germany and Spain, compared to around 10% in the UK and Italy. In France, there was an initial rapid uptake, which stabilized at around 20% after three years. Rates of uptake were lower for the other drugs, with the GLP1-RAs reaching a market share of 2.5-4.5% in Germany, Spain and France, compared to less than 2.5% in the UK and Italy. The SGLT2Is reached a market share of 5-8% in Spain and Germany, compared to less than 4% in the UK and Italy, and they were not launched at all in France in March 2020. CONCLUSION: The differences in the uptake of new antidiabetic drugs may reflect different methods for assessing and introducing new medicines, as well as cultural factors. The uptake of the new medicines would appear to be more cautious in the UK and Italy, perhaps due to concerns about cost-effectiveness, whereas in Germany and Spain, and possibly also France, a new medicine's potential benefits may be prioritized.

Onset of action of etanercept in rheumatoid arthritis based on patient-reported outcomes.

BACKGROUND: Onset of action is considered to be a key characteristic of the treatment of rheumatoid arthritis. The efficacy of TNF blockers is usually evaluated after 2 to 4 weeks of therapy. EULAR-RAID is a valid patient-reported outcome composite index. OBJECTIVES: To evaluate the onset of action of etanercept in rheumatoid arthritis patients according to the EULAR-RAID score. METHODS: An open-label, single-arm (etanercept 50 mg/week), 12-week study was carried out in patients with active rheumatoid arthritis. Patients were asked to fill in the RAID score questionnaire each day for the first 14 days of the study and at the 4-week and 12-week visits. Onset of action was evaluated by considering: a) changes over time of the EULAR-RAID score; b) the percentage of patients achieving an 'acceptable' condition according to the EULAR-RAID score (e.g. a score ≤3.00). RESULTS: Of the 120 screened patients, 108 (female: 75%), age 54±13 years, disease duration 8±7 years) were enrolled. At baseline, patients had active rheumatoid arthritis (DAS: 5.4±0.8; CRP: 18.±30mg/l). Eleven patients dropped out of the study. A statistically significant decrease in the EULAR-RAID score was observed by day 1 of therapy. Kaplan-Meier estimates of the proportion of patients achieving an acceptable RAID score were 29.8 [% 95% C.I. 23.8-X42.6], 50 % [95% C.I. 41-60.9], 51.9% [95% C.I. 43.8-63.7], 56% [95% C.I. 49.5-69.1, after 1, 2, 4 and 12 weeks of therapy respectively. The median time to achieve an acceptable EULAR-RAID score was 14.5 days. CONCLUSIONS: This open-label study suggests that patients can perceive a clinically relevant improvement by the first week of etanercept therapy.

The influence of the definition of patient global assessment in assessment of disease activity according to the Disease Activity Score (DAS28) in rheumatoid arthritis.

OBJECTIVE: Patient global assessment (PGA) is one of the 4 items included in the Disease Activity Score (DAS28) for evaluation of activity of rheumatoid arthritis (RA). We studied the influence of the use of 3 different techniques of PGA on the assessment of disease activity. METHODS: We evaluated 3 different DAS28 according to the technique of PGA in 108 patients with active RA before and after 12 weeks of etanercept therapy. RESULTS: The reliability (intraclass coefficient of correlation) between screening and baseline was very high and similar for the 3 DAS28. The percentage of patients in the different states of disease (from remission to higher disease activity) and the sensitivity to change across the 3 DAS28 scales were very similar. CONCLUSION: The different techniques of collection of PGA to be included in the DAS calculation yield similar results. However, an accepted, unequivocal technique should be encouraged in order to reduce heterogeneity in scoring DAS among patients with RA.

Familial history of cancer and childhood acute leukemia: a French population-based case-control study.

A case-control study was conducted to investigate the role of a familial history of cancer in the etiology of childhood acute leukemia. The history of cancer in the relatives of 472 cases was compared with that of 567 population-based controls. Recruitment was frequency matched on age, sex and region. The familial history of cancer in each child's relatives was reported by the mother in response to a standardized self-administered questionnaire. A familial history of solid tumor in first or second-degree relatives was associated with an increased risk of acute lymphoblastic leukemia (odds ratio (OR)=1.6 [95% confidence interval, 1.2-2.1]), while a familial history of hematopoietic malignancies in first or second-degree relatives was associated with an increased risk of acute myeloid leukemia (OR=4.3 [1.4-13]). The ORs for the histories of cancer increased with the number of relatives with cancer (OR=1.5 [1.1-2.0] for one relative and OR=2.3 [1.3-3.8] for two relatives or more; Ptrend<0.0001). Significant associations between childhood acute leukemia and familial history of genital cancers and brain tumor were also observed (OR=2.7 [1.2-5.8] and OR=10.7 [1.3-86], respectively). This study supports the hypothesis that a familial history of cancer may play a role in the etiology of childhood acute leukemia. It also evidences some specific associations that require further investigation.

Maternal alcohol and coffee drinking, parental smoking and childhood leukaemia: a French population-based case-control study.

We investigated the role of maternal alcohol and coffee drinking during pregnancy and that of parental smoking in the aetiology of childhood leukaemia. A French, population-based, case-control study was conducted, comparing 472 [407 acute lymphoblastic leukaemia (ALL) and 62 acute myeloblastic leukaemia] cases of childhood acute leukaemia (AL) and 567 population controls, frequency-matched with cases on age, gender and region of residence. Both case and control mothers filled in a comprehensive self-administered standardised questionnaire, eliciting detailed data on maternal alcohol and coffee consumption during pregnancy and parental smoking before, during and after pregnancy. Maternal alcohol consumption of more than 1 drink per day was related to ALL (OR = 2.8 [95% CI 1.8, 5.9]). While maternal coffee consumption was not significantly related to AL (OR = 1.4 [95% CI 0.9, 2.3]), highest intake of coffee (more than 3 cups per day) during pregnancy was associated with AL in children whose mothers were non-smokers (OR = 1.9 [95% CI 1.0, 3.5]). No association with parental smoking, either maternal or paternal, was observed with AL. The present results suggest a possible role of the highest consumption of alcohol by the mother during pregnancy in the aetiology of childhood AL.

Common carotid artery intima-media thickness, carotid plaques, and walking speed.

BACKGROUND AND PURPOSE: Gait dysfunction is an important cause of disability among the elderly and may be, in part, of vascular origin. We studied the association between carotid ultrasound parameters and measures of gait and balance in subjects 65 to 85 years of age who participated in the baseline phase of the Three-City Study in the Dijon center. METHODS: The study population comprised 2572 noninstitutionalized individuals. Carotid plaques and common carotid artery intima-media thickness (CCA-IMT) were measured using ultrasonography. Gait and balance measures included walking speed and a modified version of the Tinetti scale. RESULTS: Mean maximum walking speed (MWS) decreased with increasing CCA-IMT and number of plaques (P<10(-4)). Compared with subjects in the lowest CCA-IMT quintile, the odds ratio (95% CI) for being in the lowest MWS quartile was 1.1 (0.8 to 1.6) in the second, 1.3 (0.9 to 1.8) in the third, 1.7 (1.2 to 2.4) in the fourth, and 2.2 (1.6 to 3.1) in the higher CCA-IMT quintile (P<10(-4)). Mean (SD) CCA-IMT was 0.716 (0.118) mm in subjects with a modified Tinetti score <16 (25th percentile) and 0.685 (0.109) mm in subjects with a score of > or =16 (P=0.006). The proportion of subjects in the lowest MWS quartile (P=0.006) or with a modified Tinetti score <16 (P=0.05) increased with the number of plaques. These relations were attenuated after adjustment for vascular risk factors. CONCLUSIONS: Carotid plaques and higher CCA-IMT values are associated with worse performances on gait and balance tests. Our results suggest that vascular factors may play an important and under-recognized role in motor function.
