Abstract Background Influenza epidemics significantly weight on the Brazilian healthcare system and its society. Public health authorities have progressively expanded recommendations for vaccination against influenza, particularly to the pediatric population. However, the potential mismatch between the trivalent influenza vaccine (TIV) strains and those circulating during the season remains an issue. Quadrivalent vaccines improves vaccines effectiveness by preventing any potential mismatch on influenza B lineages. Methods We evaluate the public health and economic benefits of the switch from TIV to QIV for the pediatric influenza recommendation (6mo-5yo) by using a dynamic epidemiological model able to consider the indirect impact of vaccination. Results of the epidemiological model are then imputed in a health-economic model adapted to the Brazilian context. We perform deterministic and probabilistic sensitivity analysis to account for both epidemiological and economical sources of uncertainty. Results Our results show that switching from TIV to QIV in the Brazilian pediatric population would prevent 406,600 symptomatic cases, 11,300 hospitalizations and almost 400 deaths by influenza season. This strategy would save 3400 life-years yearly for an incremental direct cost of R$169 million per year, down to R$86 million from a societal perspective. Incremental cost-effectiveness ratios for the switch would be R$49,700 per life-year saved and R$26,800 per quality-adjusted life-year gained from a public payer perspective, and even more cost-effective from a societal perspective. Our results are qualitatively similar in our sensitivity analysis. Conclusions Our analysis shows that switching from TIV to QIV to protect children aged 6mo to 5yo in the Brazilian influenza epidemiological context could have a strong public health impact and represent a cost-effective strategy from a public payer perspective, and a highly cost-effective one from a societal perspective.

Abstract Acute promyelocytic leukemia (APL) is a distinct and rare morphological, clinical and pathological variant of acute myeloid leukemia (AML). It represents approximately 10% to 15% of AML.  APL is characterized by a high incidence of coagulopathy caused by disseminated intravascular coagulation and/or excessive fibrinolysis and is associated with a high early mortality.  Current first-line treatments consist of all-trans retinoic acid (ATRA), anthracyclines and conventional chemotherapy (CT). Although considerable progress has been made in the first-line treatment of APL, about 20 to 30% of patients who achieved complete remission (CR) still relapse Trisenox® is a sterile injectable solution of arsenic trioxide (ATO) and has been approved in several countries, including Canada, for the induction of remission and consolidation in patients with APL who are refractory to, or have relapsed from, retinoid and anthracycline chemotherapy. At this time, ATO is recognized as the standard treatment for relapsed or refractory APL. However, it is not reimbursed yet by provincial public health care systems and was available through a special access program in Canada until product availability. The objective of this study was to assess, from a Canadian perspective, the economic impact of ATO in the treatment of patients with relapsed or refractory APL. A time-dependent Markov model was constructed to assess the cost-effectiveness of ATO compared to ATRA+CT in the treatment of relapsed/refractory APL. Because there was no head-to-head clinical trial available, data from the ATO treatment arm were taken from Soignet, 2001, while data for ATRA+CT were taken from Thomas, 2000. The comparative treatment was composed of ATRA + sequential CT including cytarabine, mitoxantrone or etoposide, followed by autologous hematopoietic stem cell transplantation (HSCT) in consolidation as described in Thomas, 2000. The Markov model comprises five health states: induction, second remission, treatment failure/relapse, post-failure, and death. The length of each Markov cycle was one month for the first 24-month study period then of one year. The model continued to run until all patients reached the absorbing state of death. All patients started in the induction state and could move to other health states thereafter. In case of treatment relapse/failure, patients were subsequently assigned to receive an allogeneic HSCT. The model also takes into account the incidence of treatment-induced grade 3-4 toxicity reported in both clinical trials (Soignet, 2001 and Thomas, 2000). Analyses were conducted from both a Canadian Ministry of Health (MoH) and a societal perspective over a lifetime horizon. In the treatment of relapsed/refractory APL, ATO is a cost-effective strategy over ATRA+CT, from both a health care system and a societal perspective. In fact, compared with ATRA+CT, ATO is associated with an incremental cost-effectiveness ratios (ICERs) of $20,443 per QALY and $22,219 per QALY, from a MoH and societal perspective respectively. Moreover, the results of the exhaustive sensitivity analysis confirm the robustness of the base-case results. In fact, according to the deterministic analysis results, ATO remained a cost-effective strategy compared with ATRA+CT from both perspectives. The ICERs vary between $9,785 and $40,732 / QALY from a MoH perspective and between $11,561 and $44,271 / QALY from a societal perspective. Results of the probabilistic sensitivity analysis indicated that, according to a willingness to pay of $50,000, ATO remains a cost-effective strategy in 99.37% and 98.98% of the simulations, from a MoH and a societal perspective respectively. In conclusion, this economic evaluation demonstrates that ATO+ATRA is a cost-effective strategy in the treatment of relapsed/refractory APL. Disclosures: Lachaine: Lundbeck Canada: Research Funding.

Background: The RTS,S/AS01E malaria vaccine is being assessed in Malawi, Ghana and Kenya as part of a large-scale pilot implementation programme. Even if impactful, its incorporation into immunisation programmes will depend on demonstrating cost-effectiveness. We analysed the cost-effectiveness and public health impact of the RTS,S/AS01E malaria vaccine use in Malawi. Methods: We calculated the Incremental Cost Effectiveness Ratio (ICER) per disability-adjusted life year (DALY) averted by vaccination and compared it to Malawi’s mean per capita Gross Domestic Product. We used a previously validated Markov model, which simulated malaria progression in a 2017 Malawian birth cohort for 15 years. We used a 46% vaccine efficacy, 75% vaccine coverage, USD5 estimated cost per vaccine dose, published local treatment costs for clinical malaria and Malawi specific malaria indicators for interventions such as bed net and antimalarial use. We took a healthcare provider, household and societal perspective. Costs were discounted at 3% per year, no discounting was applied to DALYs. For public health impact, we calculated the DALYs, and malaria events averted. Results: The ICER/DALY averted was USD115 and USD109 for the health system perspective and societal perspective respectively, lower than GDP per capita of USD398.6 for Malawi. Sensitivity analyses exploring the impact of variation in vaccine costs, vaccine coverage rate and coverage of four doses showed vaccine implementation would be cost-effective across a wide range of different outcomes. RTS,S/AS01 was predicted to avert a median of 93,940 (range 20,490–126,540) clinical cases and 394 (127–708) deaths for the three-dose schedule, or 116,480 (31,450–160,410) clinical cases and 484 (189–859) deaths for the four-dose schedule, per 100 000 fully vaccinated children. Conclusions: We predict the introduction of the RTS,S/AS01 vaccine in the Malawian expanded programme of immunisation (EPI) likely to be highly cost effective.

Abstract Background Vedolizumab intravenous (IV), a gut selective humanised monoclonal antibody, is indicated for the management of moderately to severely active Ulcerative Colitis (UC) and has been shown in the only head-to-head clinical trial within UC to be superior to adalimumab (NCT02497469). Furthermore, the novel vedolizumab subcutaneous (SC) has recently been proven to be an effective treatment of UC (NCT02611830). The objective of this study is to estimate the comparative cost-effectiveness of vedolizumab IV with updated efficacy data, and vedolizumab SC for the first time. Both vedolizumab IV and SC have been compared with other publicly reimbursed biologics for the treatment of patients with moderate-to-severe UC from a Canadian public healthcare payer perspective. Methods A hybrid decision tree/Markov model was developed to simulate the clinical course of UC, translating the disease course into costs and quality-adjusted life-years (QALYs). Comparative efficacy of vedolizumab SC, vedolizumab IV, adalimumab, infliximab IV, and golimumab were sourced from a network meta-analysis. Drug and disease management costs (2019 $CAD) were sourced from Ontario public payer schedules of benefits. Utilities were sourced from the literature. Clinical and economic outcomes were projected over a lifetime and discounted at 1.5% annually. Results Within a mixed bio-naïve/experienced population, vedolizumab SC resulted in slightly more QALYs than vedolizumab IV and dominated adalimumab (Table 1); vedolizumab SC yielded an incremental cost-effectiveness ratio (ICER) of $CAD 6,727 per QALY and $CAD 52,673 per QALY relative to golimumab and to infliximab (for which the price of a biosimilar was used), respectively. Further scenario analysis within bio-naïve populations supported the robustness of the base-case results, demonstrating that vedolizumab SC or vedolizumab IV were either dominant or cost-effective across all scenarios. Conclusion Our analysis suggests that vedolizumab SC and vedolizumab IV are a cost-effective therapeutic alternative relative to other biologics for moderate-to-severe UC in Canada. Future research will expand the analysis across all biologic comparators as they are used in the real world.

ObjectiveThis study aimed to estimate the cost-effectiveness of direct-acting antivirals (DAAs) among patients with non-genotype 1 for the eradication of hepatitis C virus (HCV) infection in China.MethodsA decision-analytic Markov model was developed to estimate the lifetime costs, quality-adjusted life years (QALYs) and incremental cost-effectiveness ratios (ICERs) for DAAs and pegylated interferon plus ribavirin (PEG-RBV) from a societal perspective. The model inputs were derived from the literature, a patient survey, HCV expert opinions and a specialised drug price database available in China. Sensitivity analysis was conducted to evaluate the model robustness and calculate reasonable prices of DAAs.ResultsFor patients infected with HCV genotype 2, the pan-genotypic regimen sofosbuvir/velpatasvir (SOF/VEL) was the most cost-effective strategy compared with PEG-RBV, with an ICER of US$5653/QALY. For genotype 3, the combination of sofosbuvir plus daclatasvir (SOF-DCV) was the most cost-effective approach, with an ICER of US$3314/QALY. All DAA regimens for genotype 6 were cost-saving, and sofosbuvir plus ribavirin (SOF-RBV) was the optimal regimen. One-way sensitivity analysis demonstrated that the ICERs were most sensitive to the utility values, discount rate and drug costs. Probabilistic sensitivity analysis indicated that using a threshold equal to one time the gross domestic product (GDP) per capita in China (US$9769/QALY, 2018), the probability of SOF/VEL, SOF-DCV and SOF-RBV being cost-effective was 58%, 83% and 71% for genotype 2, 3 and 6, respectively. Threshold analysis showed that the price of DAAs should be reduced by some degree to achieve better affordability.ConclusionsDAAs were cost-effective compared with traditional treatments. A reasonable reduction in the price of DAAs will increase drug affordability and is of great significance as a global strategy to eradicate viral hepatitis.

Abstract Background Clinical trials in China have demonstrated that ranibizumab can improve the clinical outcomes of branch retinal vein occlusion (BRVO) and central retinal vein occlusion (CRVO). However, no economic evaluation of ranibizumab has been conducted among Chinese patient population. Methods To provide insights into the economic profile of ranibizumab among Chinese RVO population, a Markov state-transition model was used to predict the outcomes of ranibizumab comparing to laser photocoagulation and observational-only care from the societal perspective. This model simulated changes in patient visuality, quality-adjusted of life years (QALY), medical costs, and direct non-medical costs of individuals with visual impairment due to BRVO or CRVO in lifetime. The base-case analysis used an annual discount rate of 5% for costs and benefits following the China Guidelines for Pharmacoeconomic Evaluations. Deterministic and probabilistic sensitivity analyses were performed to test the robustness of the model. Results The base-case incremental cost-effectiveness ratio (ICER) comparing ranibizumab to laser photocoagulation was ¥65,008/QALY among BRVO patients and was ¥65,815/QALY among CRVO patients, respectively. Comparing to the 2019 gross domestic product (GDP) per capita of ¥71,000, both two ICERs were far below the cost-effective threshold at three times of GDP per capita (¥213,000). The deterministic and probabilistic sensitivity analyses demonstrated the base-case results were robust in most of the simulation scenarios. Conclusion The current Markov model demonstrated that ranibizumab may be cost-effective compared with laser photocoagulation to treat BRVO and cost-effective compared to observation-only care to treat CRVO in China from the societal perspective.

BackgroundPembrolizumab was recently demonstrated to have survival benefit in patients with recurrent or metastatic head and neck squamous cell carcinoma (r/mHNSCC). However, the cost-effectiveness of pembrolizumab versus chemotherapy in China remains uncertain.ObjectiveThis analysis aimed to describe the cost-effectiveness of pembrolizumab versus standard-of-care (SOC) therapy in r/mHNSCC in China.DesignA Markov model consisting of three health states (stable, progressive and dead) was developed to compare the cost and effectiveness of pembrolizumab with SOC in platinum-resistant r/mHNSCC. Model inputs for transition probabilities and toxicity were collected from the KEYNOTE-040 trial, while health utilities were estimated from a literature review. Cost data were acquired for the payer’s perspective in China. Costs and outcomes were discounted at an annual rate of 3.0%. Sensitivity analyses were conducted to test the uncertainties surrounding model parameters.Outcome measuresThe primary outcome was incremental cost-effectiveness ratios (ICERs), which were calculated as the cost per quality-adjusted life years (QALYs).ResultsThe total mean cost of pembrolizumab and SOC was US$45 861 and US$41 950, respectively. As for effectiveness, pembrolizumab yielded 0.31 QALYs compared with 0.25 QALYs for SOC therapy. The ICER for pembrolizumab versus SOC was US$65 186/QALY, which was higher than the willingness-to-pay threshold (WTP) of US$28 130/QALY in China. The univariate sensitivity analysis indicated that utility values for progressive state, probability from stable to progressive in the SOC group, as well as cost of pembrolizumab were the three most influential variables on ICER. The probabilistic sensitivity analysis demonstrated that standard therapy was more likely to be cost-effective compared with pembrolizumab at a WTP value of US$28 130/QALY. Results were robust across both univariate analysis and probabilistic sensitivity analysis.ConclusionsPembrolizumab is not likely to be a cost-effective strategy compared with SOC therapy in patients with platinum-resistant r/mHNSCC in China.Trial registration numberNCT02252042; Post-results.

Using Data

Background: The IMbrave 150 trial revealed that atezolizumab plus bevacizumab (atezo–bev) improves survival in patients with unresectable hepatocellular carcinoma (HCC) (1 year survival rate: 67.2% vs. 54.6%). We assessed the cost-effectiveness of atezo–bev vs. sorafenib as first-line therapy in patients with unresectable HCC from the US payer perspective. Methods: Using data from the IMbrave 150, we developed a Markov model to compare the lifetime cost and efficacy of atezo–bev as first-line systemic therapy in HCC with those of sorafenib. The main outcomes were life-years, quality-adjusted life-years (QALYs), lifetime costs, and incremental cost-effectiveness ratio (ICER). Results: Atezo–bev demonstrated a gain of 0.44 QALYs, with an additional cost of USD 79,074. The ICER of atezo–bev was USD 179,729 per QALY when compared with sorafenib. The model was most sensitive to the overall survival hazard ratio and body weight. If we assumed that all patients at the end of the IMbrave 150 trial were cured of HCC, atezo–bev was cost-effective (ICER USD 53,854 per QALY). However, if all patients followed the Surveillance, Epidemiology, and End Results data, the ICER of atezo–bev was USD 385,857 per QALY. Reducing the price of atezo–bev by 20% and 29% would satisfy the USD 150,000/QALY and 100,000/QALY willingness-to-pay threshold. Moreover, capping the duration of therapy to ≤12 months or reducing the dosage of bev to ≤10 mg/kg would render atezo–bev cost-effective. Conclusions: The long-term effectiveness of atezo–bev is a critical but uncertain determinant of its cost-effectiveness. Price reduction would favorably influence cost-effectiveness, even if long-term clinical outcomes were modest. Further studies to optimize the duration and dosage of therapy are warranted.

Abstract Background TAS-102 plus bevacizumab is an anticipated combination regimen for patients who have metastatic colorectal cancer. However, evidence supporting its use for this indication is limited. We compared the cost-effectiveness of TAS-102 plus bevacizumab combination therapy with TAS-102 monotherapy for patients with chemorefractory metastatic colorectal cancer. Method Markov decision modeling using treatment costs, disease-free survival, and overall survival was performed to examine the cost-effectiveness of TAS-102 plus bevacizumab combination therapy and TAS-102 monotherapy. The Japanese health care payer’s perspective was adopted. The outcomes were modeled on the basis of published literature. The incremental cost-effectiveness ratio (ICER) between the two treatment regimens was the primary outcome. Sensitivity analysis was performed and the effect of uncertainty on the model parameters were investigated. Results TAS-102 plus bevacizumab had an ICER of $21,534 per quality-adjusted life-year (QALY) gained compared with TAS-102 monotherapy. Sensitivity analysis demonstrated that TAS-102 monotherapy was more cost-effective than TAS-102 and bevacizumab combination therapy at a willingness-to-pay of under $50,000 per QALY gained. Conclusions TAS-102 and bevacizumab combination therapy is a cost-effective option for patients who have metastatic colorectal cancer in the Japanese health care system.
