Pharmacoeconomic analysis of paliperidone palmitate for treating schizophrenia in Greece

BACKGROUND: Patients having chronic schizophrenia with frequent relapses and hospitalizations represent a great challenge, both clinically and financially. Risperidone long-acting injection (RIS-LAI) has been the main LAI atypical antipsychotic treatment in Greece. Paliperidone palmitate (PP-LAI) has recently been approved. It is dosed monthly, as opposed to biweekly for RIS-LAI, but such advantages have not yet been analysed in terms of economic evaluation. PURPOSE: To compare costs and outcomes of PP-LAI versus RIS-LAI in Greece. METHODS: A cost-utility analysis was performed using a previously validated decision tree to model clinical pathways and costs over 1 year for stable patients started on either medication. Rates were taken from the literature. A local expert panel provided feedback on treatment patterns. All direct costs incurred by the national healthcare system were obtained from the literature and standard price lists; all were inflated to 2011 costs. Patient outcomes analyzed included average days with stable disease, numbers of hospitalizations, emergency room visits, and quality-adjusted life-years (QALYs). RESULTS: The total annual healthcare cost with PP-LAI was €3529; patients experienced 325 days in remission and 0.840 QALY; 28% were hospitalized and 15% received emergency room treatment. With RIS-LAI, the cost was €3695, patients experienced 318.6 days in remission and 0.815 QALY; 33% were hospitalized and 17% received emergency room treatment. Thus, PP-LAI dominated RIS-LAI. Results were generally robust in sensitivity analyses with PP-LAI dominating in 74.6% of simulations. Results were sensitive to the price of PP-LAI. CONCLUSIONS: PP-LAI appears to be a cost-effective option for treating chronic schizophrenia in Greece compared with RIS-LAI since it results in savings to the health care system along with better patient outcomes

Hair regrowth treatment efficacy and resistance in androgenetic alopecia: A systematic review and continuous Bayesian network meta-analysis

BackgroundAndrogenetic alopecia (AGA) affects almost half the population, and several treatments intending to regenerate a normal scalp hair phenotype are used. This is the first study comparing treatment efficacy response and resistance using standardized continuous outcomes.ObjectiveTo systematically compare the relative efficacy of treatments used for terminal hair (TH) regrowth in women and men with AGA.MethodsA systematic literature review was conducted (from inception to August 11, 2021) to identify randomized, Placebo-controlled trials with ≥ 20 patients and reporting changes in TH density after 24 weeks. Efficacy was analyzed by sex at 12 and 24 weeks using Bayesian network meta-analysis (B-NMA) and compared to frequentist and continuous outcomes profiles.ResultsThe search identified 2,314 unique articles. Ninety-eight were included for full-text review, and 17 articles met the inclusion criteria for data extraction and analyses. Eligible treatments included ALRV5XR, Dutasteride 0.5 mg/day, Finasteride 1 mg/day, low-level laser comb treatment (LLLT), Minoxidil 2% and 5%, Nutrafol, and Viviscal. At 24 weeks, the B-NMA regrowth efficacy in TH/cm2 and significance (**) in women were ALRV5XR: 30.09**, LLLT: 16.62**, Minoxidil 2%: 12.13**, Minoxidil 5%: 10.82**, and Nutrafol: 7.32**, and in men; ALRV5XR: 21.03**, LLLT: 18.75**, Dutasteride: 18.37**, Viviscal: 13.23, Minoxidil 5%: 13.13**, Finasteride: 12.38, and Minoxidil 2%: 10.54. Two distinct TH regrowth response profiles were found; Continuous: ALRV5XR regrowth rates were linear in men and accelerated in women; Resistant: after 12 weeks, LLLT, Nutrafol, and Viviscal regrowth rates attenuated while Dutasteride and Finasteride plateaued; Minoxidil 2% and 5% lost some regrowth. There were no statistical differences for the same treatment between women and men. B-NMA provided more accurate, statistically relevant, and conservative results than the frequentist-NMA.ConclusionSome TH regrowth can be expected from most AGA treatments with less variability in women than men. Responses to drug treatments were rapid, showing strong early efficacy followed by the greatest resistance effects from flatlining to loss of regrowth after 12–16 weeks. Finasteride, Minoxidil 2% and Viviscal in men were not statistically different from Placebo. LLLT appeared more efficacious than pharmaceuticals. The natural product formulation ALRV5XR showed better efficacy in all tested parameters without signs of treatment resistance (see Graphical abstract).Systematic review registrationwww.crd.york.ac.uk/PROSPERO/display_record.asp?ID=CRD42021268040, identifier CRD42021268040

Willingness to Pay for a Treatment for Pain in Multiple Sclerosis

BackgroundBackground Multiple sclerosis (MS) is a chronic neurological disease that affects 240 per 100 000 Canadians. Of these patients, 10-80% (average 70%) experience pain. Sativex is a cannabis-based drug recently approved for neuropathic pain. Abstract: ObjectivesObjectives In this study, we determine individuals' preferences between two treatment options as well as the willingness to pay (WTP) for Sativex, expressed as the amount they would pay in insurance premiums to have access to that treatment. Abstract: MethodsMethods The WTP instrument comprised a decision board as a visual aid, and a questionnaire. A decision board helps clinicians standardize the presentation of treatment information. In this study, the decision board described two treatment options: a three-drug combination (gabapentin, amytriptyline, acetaminophen [paracetamol] {i.e. pills}) and the three-drug combination plus Sativex (i.e. 'pills and oral spray'). Information on efficacy and adverse effects was taken from trial data; wording was guided by a panel of neurologists and tested for clarity on lay people. The instrument was administered to 500 participants from Canada's general population using the bidding game approach. Descriptive statistics were calculated. Abstract: ResultsResults Mean (SD) age of participants was 39 (13) years, with a female : male distribution of 56 : 44. The decision board was presented in both English (85%) and French (15%). Of 500 interviewees, 253 (50.6%) chose the 'pills and oral spray'. Mean monthly WTP for the insurance premium for those who chose the 'pills and oral spray' was $Can8 (SD ± 15, median 4, range 0-200). Abstract: ConclusionsConclusions Assuming that 51% of the general population are willing to pay additional premiums as reported in this study, the premiums collected would cover the cost of Sativex for all Canadian MS patients experiencing pain, with a surplus.

Pain Due to Multiple Sclerosis: Analysis of the Prevalence and Economic Burden in Canada

BACKGROUND: Multiple sclerosis (MS) is a neurological disease affecting approximately 50,000 Canadians. Although studies have described overall MS costs, none have focused specifically on MS-related pain.OBJECTIVES: To estimate the prevalence of MS-related pain in Canada, the proportion of patients treated and responding to treatment for MS-related pain, and the associated economic burden.METHODS: Results were captured through physician and patient surveys. Patients were recruited through MS clinics and the MS Society. Patient-reported outcomes and resource utilization over the previous six months were collected by telephone interview. Costs were measured in 2004 Canadian dollars. The economic burden was extrapolated to the population using national demographics and prevalence. Spearman’s ρ assessed the relationship between cost and pain severity.RESULTS: Physicians estimated that 46% of their MS patients experienced MS-related pain, and that 35% received treatment for pain. Pain was reported to be relieved somewhat in 29%±10% of their patients, adequately in 26%±19% and poorly in 27%±13%, while 17%±9% received no relief. Two hundred ninety-seven participants completed the patient survey. Seventy-one per cent (211 of 297 patients) experienced MS-related pain. Eighty per cent of patients reported taking some type of medication to manage their pain, and of these, 82% reported some reduction in pain. The mean ± SD direct cost per patient of MS-related pain was $2,528±5,695. The mean ± SD indirect cost per patient was$669±875. Total costs were positively correlated with levels of self-reported pain (ρ=0.291, Pud_less_than0.0001). The estimated six-month burden of pain of MS patients in Canada was $79,444,888.CONCLUSIONS: The prevalence of pain is high in MS patients. This condition may be underdiagnosed and undertreated, and results in a significant economic burden on society.Peer Reviewe
