Study of the Direct Costs of Asthma at a Healthcare Service Provider in Bogotá, Colombia.

OBJECTIVES: This study aimed to describe clinical characteristics and direct medical costs associated with disease treatment in Colombia patients with asthma from 1 healthcare provider. METHODS: This was a descriptive study with a retrospective data collection from a healthcare provider's electronic medical records in Colombia. A clinical, demographic, and healthcare resource utilization profile was developed over a 12-month observation period after the identification of eligible patients. To determine the mean cost per patient per year, the total frequencies of resource utilization were added, and the result was multiplied by the unit cost of each of them. RESULTS: A total of 7919 patients were included in the analysis. The mean ± SD cost per patient per year ranged from $189.5 ± $1.900.6 to $240.2 ± $1.903.6 depending on the price guidebook. The total cost had been driven by the medication use (79% of total cost) and by the outpatient visits (20% of total cost). CONCLUSIONS: In the population analyzed, the mean total direct cost per patient per year of asthma was $189.5 and $240.2, depending on the cost source. Direct medical costs were higher in cases classified as severe and in the adult and elderly population. When comparing the sources of resource utilization, it was found that the mean cost per patient obtained from real-life data is lower than the theoretical cost obtained from the bottom-up method with quantification of resources from experts. It is important to consider limitations related to study design and the evolving landscape of asthma treatments.

Estimating the health economic impact of the universal varicella vaccination in Argentina from 2015 to 2019.

Since the introduction of Universal Varicella Vaccination (UVV) in the Argentinean National Immunization Program in 2015, a significant decline in the incidence of varicella has been reported. This study aimed to estimate the economic impact of single-dose UVV in Argentina from 2015 to 2019. The economic impact was assessed based on the observed incidence of varicella in the post-UVV period and the number of cases avoided, obtained from a previously published study that used an Autoregressive Integrated Moving Average (ARIMA) model. The weighted average cost per case was calculated using local studies. The post-UVV cost reductions were calculated by multiplying the number of cases avoided from 2015 -2019 by the weighted average cost per case. Data were summarized yearly and by peak (September-November) periods for the target (1-4 years) and overall populations. We estimated avoided costs of United States dollars (USD) $65 million in the target population and $112 million in the overall population over 4 years following UVV introduction. We observed a trend toward greater reductions in costs over time, with substantial differences observed in peak periods. We estimated that the single-dose UVV program considerably reduced the economic burden of varicella in Argentina by avoiding direct and indirect costs associated with varicella management.

Effectiveness and safety of caplacizumab in acquired thrombotic thrombocytopenic purpura: health technology assessment and classification according to the methodology established in Colombia.

OBJECTIVES: Acquired thrombotic thrombocytopenic purpura (aTTP) is a rare hematological disease whose clinical management includes caplacizumab along with plasma exchange and immunosuppression, according to international guidelines. Caplacizumab has been available in Colombia since 2022. This study seeks to determine the therapeutic classification of caplacizumab according to the methodology of the Instituto de Evaluación Tecnológica en Salud. METHODS: The classification was carried out through a deliberative process following the modified Delphi technique, with a panel of experts, made up of four hemato-oncologists, a pharmaceutical chemist, and a patient. The results of effectiveness and safety obtained through a systematic review, therapeutic thresholds (clinical significance), and degree of acceptability (willingness to use the technology) were used for the classification. RESULTS: Fourteen effectiveness and safety outcomes were submitted for the classification process. Caplacizumab showed clinical significance for some effectiveness outcomes, was not considered inferior in terms of safety, and displayed acceptability of use. Through consensus, the panel determined that caplacizumab plus the standard regimen is superior to the standard regimen in terms of treatment response and composite outcome, and no different for the other effectiveness and safety outcomes. Likewise, in overall terms, the panel determined that caplacizumab together with the standard regimen is superior to the standard regimen. CONCLUSION: Treatment with caplacizumab together with the standard regimen was considered superior to the standard regimen for the treatment of patients with aTTP, as it showed clinically significant benefits in critical outcomes for decision making, and a safety profile no different to its comparator.

Burden of disease of chronic pain in Ecuador.

OBJECTIVES: To estimate the burden of disease related to chronic pain in Ecuador. METHODS: We used Global Burden of Disease (GBD) methods to estimated disability-adjusted life years (DALYs) related to chronic pain in Ecuador related to lumbar pain, osteoarthritis, post-herpetic neuralgia, diabetic neuropathy, cancer-related pain, and other musculoskeletal pain. We estimated the prevalent cases by sex and age group using literature data. We only estimated years lived with disability using disability weights obtained from the GBD, with the assumption that no premature death would be related to pain. We used a prevalence-based approach to estimate cases by sex and age group using literature, without discounting or age adjustment. We calculated total DALYs and DALYs/100,000 inhabitants. RESULTS: Our estimated yielded a total of 3,644,108 patients with chronic pain. They would produce 256,090 DALYs or 1,483 DALYs/100,000 inhabitants attributable to chronic pain. Low back pain, osteoarthritis and cancer-related pain were the drivers of DALY production. CONCLUSIONS: Chronic pain is an important source of burden of disease. It is comparable to other important causes such as headaches, stroke, diabetes and chronic obstructive pulmonary disease, among others. Low back pain, osteoarthritis and other musculoskeletal pain were the biggest contributors given their high prevalence.

Estimate of the cost per responder for treatment with biological therapies of moderate-to-severe plaque psoriasis in Colombia for first-year and maintenance periods.

INTRODUCTION: Psoriasis is a chronic systemic inflammatory disease manifesting as erythematous and desquamative dermatoses. OBJECTIVES: This study estimated the cost per responder (CPR) for the treatment of moderate-to-severe plaque psoriasis with biologic therapies approved by the Colombian regulatory agency. METHODS: This secondary study used a modeling based CPR estimation to evaluate psoriasis therapies in Colombia. We calculated CPR of achieving Psoriasis Area and Severity Index (PASI) scores of 75, 90, and 100 for biological treatments based on the number needed to treat (NNT), reported in previously published network meta-analyses. We calculated CPR for the first year and for the maintenance period. We ranked alternatives using the estimated CPR from each literature source using the Borda count method. RESULTS: Adalimumab, infliximab and etanercept were the least expensive alternatives. Ixekizumab, guselkumab and secukinumab were the treatments with the lowest NNT for PASI 75, 90, and 100. For both first year and maintenance periods, adalimumab, infliximab, guselkumab and ixekizumab had the lowest CPR. Sensitivity analyzes showed consistent results. CONCLUSIONS: The application of CPR analysis of biologics to treat plaque psoriasis demonstrated that adalimumab, infliximab, guselkumab, and ixekizumab had the lowest CPR in the first year of treatment and during the maintenance period.

Burden of disease of chronic pain in Colombia.

OBJECTIVES: To assess the burden of disease of chronic pain in Colombia. METHODS: We estimated disability adjusted life years (DALYs) attributable to chronic pain using Global Burden of Disease (GBD) method. We identified diagnostic codes related to chronic pain considering lumbar pain, osteoarthritis, post-herpetic neuralgia, diabetic neuropathy, cancer-related pain, and others. We estimated the prevalent cases by sex and age-group using local administrative databases and literature. We assumed that pain would not cause premature death, so we only estimated years lived with disability using disability weights obtained from the GBD. We used a prevalence-based approach, without discounting or age-group adjustment. We calculated total DALYs and DALYs/100,000 inhabitants. RESULTS: We estimated a total of 5,545,019 patients with chronic pain. We calculated 491,626 DALYs or 976 DALYs/100,000 inhabitants attributable to chronic pain. Low back pain, osteoarthritis, and cancer-related pain were the most important groups. CONCLUSIONS: This study estimates that chronic pain contributes a significant quantity of DALYs, especially related to low back pain, osteoarthritis, and cancer-related pain. Chronic pain should be considered in the public health agenda.

The impact of universal varicella vaccination on the clinical burden of varicella in Colombia: A National database Analysis, 2008-2019.

In 2015, one-dose universal varicella vaccination (UVV) was introduced in the Colombian National Immunization Program targeting children aged 12 months, expanding to a two-dose program in 2019. This study aimed to examine the effect of one-dose UVV on the burden of varicella in Colombia. A retrospective study was conducted using national databases to estimate incidence and mortality for the target (1-4 years old), non-target (less than 1 and 5 years and older) and overall (all age groups) populations from the pre-UVV period (January 2008-June 2015) to the post-UVV period (July 2015-December 2019). A time-series analyses with ARIMA modeling was used to project expected varicella incidence and mortality in the absence of UVV in the post-UVV period. UVV impact was estimated by comparing predicted and observed values, providing point estimates and prediction intervals (PI). Overall vaccination coverage rate was over 90 % from 2016-2019. Following UVV introduction, mean annual incidence rates reduced from 743.6 to 676.8 per 100,000 in the target population and from 203.2 to 198.1 per 100,000 in the overall population. Our study estimated a reduction in varicella incidence from 2017, with the highest reduction of 70.5 % (95 % PI: 78.2-54.2) and 54.8 % (95 % PI: 65.0-36.4) observed in 2019 for the target and the overall populations, respectively. The ARIMA model estimated UVV in Colombia to have prevented 198,236 varicella cases from 2015 to 2019. Mortality reduced in the overall population from 0.8 per 1,000,000 to 0.5 per 1,000,000 and from 1.3 per 1,000,000 to 0.5 per 1,000,000 in the target population, in the pre-UVV and post-UVV periods, respectively. However, these differences were not statistically significant. Our study showed a significant reduction in varicella incidence after implementation of a one-dose UVV program in Colombia, increasing over time. Further assessment is needed to evaluate the impact of a two-dose UVV program in Colombia.

Trends in Varicella Burden of Disease Following Introduction of Routine Childhood Varicella Vaccination in Argentina: A 12-Year Time Series Analysis.

One-dose universal varicella vaccination (UVV) was introduced in the Argentinian National Immunization Program in July 2015. This study examined the impact of one-dose UVV on varicella incidence and mortality in Argentina. Incidence and mortality data were obtained from official databases for pre-UVV (January 2008-June 2015) and post-UVV (July 2015-December 2019) periods. Time series analyses with autoregressive integrated moving average (ARIMA) modeling predicted varicella incidence and mortality in absence of UVV in the target (aged 1-4 years) and overall population. Predicted and observed values post-UVV were compared to estimate UVV impact. Mean annual incidence rates per 100,000 reduced from 1999 (pre-UVV) to 1122 (post-UVV) in the target population and from 178 to 154 in the overall population. Significant declines in incidence were observed, reaching reductions of 83.9% (95% prediction interval [PI]: 58.9, 90.0) and 69.1% (95% PI: 23.6, 80.7) in the target and overall populations, respectively, during peak months (September-November) post-UVV. Decreasing trends in mortality rate from 0.4 to 0.2 per 1,000,000 population were observed. Over the last four years, one-dose UVV has significantly reduced varicella burden of disease in Argentina. Continuous efforts to improve vaccination coverage rates and long-term follow-up are needed to better understand the benefits of the UVV program.

Budgetary impact analysis of alteplase - recombinant tissue plasminogen activator (rtPA) - as a thrombolytic treatment for acute ischemic stroke in Colombia.

INTRODUCTION: Thrombolysis is effective for treating acute ischemic stroke (AIS). Trials have evaluated its effectiveness at different timepoints after stroke. The objective of the study was to evaluate the clinical and budgetary impact of increasing the proportion of thrombolyzed acute ischemic stroke patients in Colombia. METHODS: The budgetary impact was estimated for a 5-year time horizon from the perspective of the third-party payer. Costs were estimated using local standardized methods and expressed in US dollars of 2020. We compared two scenarios: a current one and an alternative one, with doubled thrombolysis access. RESULTS: The increase in thrombolyzed patients would decrease the number of patients with sequelae by 1,721, 2,594 and 1,007 in the ranges of 0-90 minutes, 91-180 and 181-270, respectively. The budget effort increase for each of the treatment initiation ranges is of USD$15,525,649(+5.5%), USD$16,665,304(+5.7%) and USD$16,963,231(+7.0%), respectively. CONCLUSIONS: Doubling the number of patients with AIS who are thrombolyzed would lead to reductions in the number of patients with sequelae and would require a budgetary effort of 5.5-7.0%. The early initiation of treatment gives an additional benefit in reducing the number of sequelae and a lower budgetary impact than initiation within the later time window.

Cost-effectiveness of dapagliflozin compared to DPP-4 inhibitors as combination therapy with metformin in the treatment of type 2 diabetes mellitus without established cardiovascular disease in Colombia.

INTRODUCTION: SGLT2 inhibitors or DPP-4 inhibitors are among the preferred options in patients with type 2 diabetes mellitus (T2DM) without established cardiovascular disease. OBJECTIVE: To evaluate the incremental cost-effectiveness of dapagliflozin versus DPP-4 inhibitors as a complement to metformin in the treatment ofT2D, from the perspective of the Colombian health system. METHODS: The Cardiff model was used to estimate the incremental cost-effectiveness ratio (ICER) of dapagliflozin plus metformin compared to DPP-4 inhibitors plus metformin in adults with T2DM who did not respond adequately to metformin monotherapy. We estimated the incidence of micro- and macrovascular complications from risk equations incorporating the effect of treatment. The time horizon for analysis was 5 years and a discount rate of 5% was applied, for both costs and outcomes. The costs were expressed in 2020 USD (1 USD = $3,693.36 COP). RESULTS: Dapagliflozin in association with metformin resulted in a higher number of quality-adjusted life years (QALYs) compared to the intervention. The ICER was US$1,964.80 per QALY gained. CONCLUSION: From the point of view of Colombian healthcare system, the combination of dapagliflozin with metformin is a cost-effective option compared to DPP-4 + metformin inhibitors in the treatment of T2D without established cardiovascular disease.

Cost-consequence analysis of diagnosis and early treatment of acquired thrombotic thrombocytopenic purpura in Colombia.

INTRODUCTION: The objective of the study was to evaluate the costs and benefits of early identification and treatment (within 24 hours of admission) of patients with aTTP in Colombia. METHODS: A cost-consequence analysis was conducted to evaluate the costs and health outcomes of diagnosis and early treament versus no treatment (scenario 1) and late treatment (scenario 2) in a hypothetical cohort of 100 patients with aTTP. The analysis perspective was that of the third-party payer. RESULTS: In scenario 1, he total cost of early treatment was USD$515,157 compared to USD$293,265 for no treatment. Early treatment avoided 65 deaths in the hypothetical cohort. The cost per death avoided was USD$3,414. In scenario 2, the cost of early treatment was USD$935,507 compared to USD$809,103 in the late start of treatment. By treating patients early, 33 deaths were avoided, 23 patients were estimated to be alive without exacerbations and 16 without relapses. The cost per death avoided was USD$3,879 and the cost per patient alive without exacerbations and relapses was USD$5,611 and USD$7,858, respectively. CONCLUSIONS: The early identification and treatment of patients with aTTP are associated with benefits in survival and recurrence-free survival, and an incremental cost in the process of care compared to no treatment or late treatment.

Cost-utility of dapagliflozin plus standard treatment compared to standard treatment for the management of heart failure with reduced ejection fraction in Colombia.

INTRODUCTION: The DAPA-HF study has shown that dapagliflozin added to standard treatment reduced the risks of worsening of heart failure or cardiovascular death compared to placebo. OBJECTIVES: To evaluate the cost- utility of dapagliflozin in combination with standard treatment compared to standard treatment alone for the treatment of heart failure with reduced ejection fraction from the perspective of the Colombian health system. METHODS: A Markov model using information from the DAPA-HF study was adapted to the Colombian setting. Health states considered symptom score, and transient health states were included to assess the incidence of consultations and hospitalizations for heart failure. The time horizon was 5 years and a 5% discount rate was applied. The costs were expressed in US dollars of 2020 (1 USD =$3,693.36 COP). RESULTS: The incremental cost-effectiveness ratio (ICER) of the intervention compared to standard treatment was USD $5,946 per quality adjusted life year gained. The ICER remained below the cost-effectiveness threshold in sub-group analyses. 97% of sensitivity analysis simulations showed an ICER below the cost-effectiveness threshold. CONCLUSION: From the perspective of the analysis, the addition of dapagliflozin to standard treatment is a cost-effective option in patients with heart failure with reduced ejection fraction in Colombia.

Costoefectividad del régimen combinado de mirabegron/solifenacina en el tratamiento del síndrome de vejiga hiperactiva en Colombia / Cost-effectiveness of the Combined Regimen of Mirabegron/Solifenacin in the Treatment of Overactive Bladder Syndrome in Colombia

Objetivo Evaluar la costoefectividad incremental del régimen combinado de mirabegron/solifenacina en comparación con el uso temprano de toxina botulínica, desde la perspectiva del sistema de salud colombiano, para el tratamiento de adultos con vejiga hiperactiva. Métodos Se empleó un modelo de Markov en que se comparan dos secuencias de tratamiento, una con y otra sin mirabegron/solifenacina, para evaluar la costoefectividad en un horizonte temporal de cinco años. Debido a la perspectiva de análisis, sólo se tuvieron en cuenta los costos médicos directos. La eficacia del tratamiento evaluado y su comparador fue medida en términos de la reducción de episodios diarios de incontinencia y de la frecuencia de micciones. Los costos fueron expresados en pesos colombianos de 2019, y se aplicó una tasa de descuento de 5% tanto para desenlaces como para costos. Resultados Para el caso base, el costo del tratamiento en la secuencia que incluye mirabegron/solifenacina fue mayor, pero generó un mayor número de años de vida ajustados por calidad, y así e obtuvo una razón de costoefectividad incremental de $13.637,184 si se considera el desenlace de reducción de episodios diarios de incontinencia de 50%, y de $29.313,848 si se considera el del 100%. Conclusiones De acuerdo con los resultados de esta evaluación, para un horizonte de análisis de cinco años, la secuencia de tratamiento con mirabegron/solifenacina es una alternativa costoefectiva, si se considera un umbral de disposición a pagar de tres veces el producto interno bruto (PIB) per cápita.

Aim To evaluate the incremental cost-effectiveness of the combined regimen of mirabegron/solifenacin compared with the early use of botulinum toxin, from the perspective of the Colombian health system, for the treatment of adults with overactive bladder. Methods A Markov model comparing two treatment sequences, one with and one without mirabegron/solifenacin, was used to assess cost-effectiveness over a five-year period. Due to the perspective of the analysis, only direct medical costs were considered. The efficacy of the evaluated treatment and its comparator was measured in terms of the reduction in the daily incontinence episodes and the frequency of micturition. The costs were expressed in Colombian pesos of 2019, and a discount rate of 5% was applied for both outcomes and costs. Results For the base case, the cost of the treatment in the sequence that includes mirabegron/solifenacin was higher, but it generated a greater number of quality-adjusted years of life, thus obtaining an incremental cost-effectiveness ratio of $13,637,184 when considering the outcome of 50% of reduction in the daily incontinence episodes, and $29,313,848 when considering 100%. Conclusions According to the results of the present assessment, for a five-year period of analysi, the mirabegron/solifenacin treatment sequence is a cost-effective alternative when considering a threshold of willingness to pay three times the per capita gross domestic product (GDP).

Cost-Effectiveness of the Dabrafenib Schedule in Combination With Trametinib Compared With Other Targeted Therapies, Immunotherapy, and Dacarbazine for the Treatment of Unresectable or Metastatic Melanoma With BRAFV600 Mutation in Colombia.

OBJECTIVES: Advanced melanoma accounts for 4% of malignant skin tumors, and approximately 80% of deaths are attributed to it. The most frequent mutation of the RAF gene is BRAFV600, which has been associated with a worse prognosis. The objective of the research was to evaluate the cost-effectiveness of the combined regimen of dabrafenib plus trametinib (D + T) compared with other targeted therapies, immunotherapy, and dacarbazine for the treatment of unresectable/metastatic melanoma with BRAFV600 mutation from the perspective of the Colombian health system. METHODS: A partitioned survival model with 3 states (progression-free survival, progression, and death) was used to evaluate the cost-effectiveness for a time horizon of 20 years. Owing to the perspective of the analysis, only direct medical costs were taken into account. The efficacy of the evaluated treatment and the comparators were measured in terms of overall survival and progression-free survival. All costs were expressed in Colombian pesos as of 2018, and outcomes and costs were discounted at 5% annually. Two analysis scenarios were considered, one in which only monitoring and follow-up costs were included in the progression phase and another in which costs of acquisition of possible treatment sequences were also included. RESULTS: In the first scenario (without postprogression medication costs), the combined D + T regimen was a dominant alternative to vemurafenib + cobimetinib but was not a cost-effective option compared with vemurafenib, nivolumab, ipilimumab, nivolumab + ipilimumab, pembrolizumab, and dacarbazine. In the second scenario (with drug costs in postprogression), D + T was dominant compared with vemurafenib + cobimetinib and cost-effective compared with nivolumab and pembrolizumab. Compared with other schemes, the incremental cost-effectiveness ratio was above the threshold of 3 gross domestic product per capita. Probabilistic sensitivity analyses showed that a willingness-to-pay threshold of Col$56 484 300 (US$19 108) per quality-adjusted life-year would not be reached at the current price of schema in Colombia. CONCLUSIONS: The combined scheme could be a cost-effective and even a cost-saving alternative to vemurafenib + cobimetinib, nivolumab, and pembrolizumab if the costs associated with the use of other medications are taken into account after progression to the first line of treatment. Compared with the other comparators, it produces a greater number of quality-adjusted life-years, but the incremental cost-effectiveness ratio is above that of the willingness to pay.

Analysis of the experience of the geriatric fracture program in two institutions in Colombia: a reproducible model? / Análisis de la experiencia del programa de fracturas geriátricas en dos instituciones en Colombia: ¿un modelo reproducible?

Abstract Background: hip fracture is the major cause of morbidity and mortality. Geriatric fracture programs promise to improve the quality of care, health outcomes and reduce costs. Objective: To describe the results related to the Geriatric fracture programs implementation in two Colombian institutions to assess reproducibility. Methods: We performed A retrospective descriptive study of the patients treated under the Geriatric fracture programs in two institutions in Colombia. The information was collected from the initial year of implementation until 2018. Demographic characteristics, length of stay, hospitalization complications, readmissions and mortality were described. Consumption of healthcare resources was defined using base cases determined with local experts and costs were estimated using standard methods. Results: 475 patients were included in the Geriatric fracture programs. We observed an increase in the number of patients. The length of stay decreased between 8.5% and 26.1% as did the proportion of total complications, with delirium having the greatest reduction. A similar situation was seen for first year mortality (from 10.9% to 4.7%), in-hospital deaths and readmissions. Estimates of costs of stay and complications showed reductions in all scenarios, varying between 22% and 68.3%. Conclusions: The present study presents the experience of two institutions that implemented the Geriatric fracture programs with increase in the number of patients treated and reductions in the time of hospital stay, the proportion of complications, readmissions, mortality and estimated costs. These are similar between both institutions and with other published implementations. This could hint that geriatric fracture program may be implemented with reproducible results.

Incremental cost-effectiveness analysis of tyrosine kinase inhibitors in advanced non-small cell lung cancer with mutations of the epidermal growth factor receptor in Colombia.

OBJECTIVE: To estimate the cost-effectiveness of sequences starting with tyrosine kinase inhibitors (TKI), afatinib and osimertinib, for the treatment of epidermal growth factor receptor (EGFR) mutation-positive (Exon 19 deletion or L858R) non-small cell lung cancer (NSCLC), stages IIIB - IV in Colombia. METHODS: A partitioned survival model was designed, using information from global and progression-free survival curves. For first and second-generation TKI, second line treatment was assumed according to the presence of T790M mutation to define the use of osimertinib or chemotherapy. The cost of the states without progression and post-progression was estimated using the base case approach, identified through consultation with clinical experts. RESULTS: The cost of treatment starting with afatinib in the first line was of 222,247 USD (1 USD = 3171.99 COP) and produced 1.36 QALYs. The strategy with afatinib was dominant with respect to that of first line TKI (227,289 USD and 1.34 QALY). The strategy with osimertinib resulted in more QALYs and higher costs, with ICERs of 35,062 USD, exceeding the current willingness to pay threshold for Colombia. CONCLUSIONS: Treatment starting with afatinib in the first line is dominant with respect to the strategy with first line TKI. The ICER of osimertinib sequence exceeds the threshold when compared with afatinib one.

Efficacy and safety of dabrafenib-trametinib in the treatment of unresectable or metastatic melanoma with BRAF V600 mutation: A systematic review and network meta-analysis.

The current systematic review aimed to evaluate the efficacy and safety of dabrafenib plus trametinib (dabrafenib-trametinib) with those of other therapeutic alternatives in the treatment of patients with BRAF V600 mutation unresectable or metastatic melanoma. The search was carried out on four databases up to July-2018. Two separate network meta-analyses (NMA) were performed using the frequentist method (random effects): one with an exclusive population with BRAF V600 mutation (NMA-pBRAFV600) and another with a mixed population (with or without the mutation: NMA-pMixed). An evidence profile was included using the GRADE method for NMA. The validity of the final estimator in the NMA-pMixed was assessed via sensitivity analysis. Five clinical trials were included in the NMA-pBRAFV600. In the NMA-pBRAFV600 population, dabrafenib-trametinib had a favorable effect on overall survival (OS) and progression-free survival (PFS) compared with dabrafenib, vemurafenib, and dacarbazine, and on partial response rate (PRR) and overall response rate (ORR) compared with dacarbazine and vemurafenib. In the NMA-pMixed population, dabrafenib-trametinib had a positive effect on OS vs ipilimumab 3 mg/kg and on PFS and PRR vs ipilimumab (3 and 10 mg/kg), nivolumab, and pembrolizumab. However, dabrafenib-trametinib, and vemurafenib-cobimetinib were comparable in terms of clinical efficacy. In addition, dabrafenib-trametinib was associated with less grades 3 and 4 adverse events.

International Experience in Therapeutic Value and Value-Based Pricing: A Rapid Review of the Literature.

OBJECTIVES: To characterize at a global level the concept of therapeutic value (TV) and describe the experience of value-based pricing (VBP) policies in 6 reference countries. METHODS: We conducted a rapid review of the literature that addressed 2 exploratory research questions. A systematic and exhaustive search was carried out up to July 2018 in MEDLINE (Ovid), Embase, Scopus, and Web of Science. RESULTS: The concepts of TV and VBP are related; value frameworks for medicines should include social preferences, comparative effectiveness, safety, adoption viability, social impact, high quality of evidence, severity of illness, and innovation. The added therapeutic value (ATV) is the manner of measuring the therapeutic advantages of new medicines compared with existing ones in terms of comparative effectiveness and safety. There are variations in the mechanisms of reimbursement and drug pricing regulation between the countries of study. CONCLUSION: In a VBP system it is essential to establish the TV and ATV of a new medicine. Although there are no methodological guidelines for the implementation of VBP policies, the process implies from the beginning the definition of TV categories that will be included in the drug pricing and reimbursement systems. Agreements between the pharmaceutical industry and governments have become a useful tool as a negotiating mechanism in most countries.
