Cost-effectiveness analysis comparing ceftazidime/avibactam (CAZ-AVI) as empirical treatment comparing to ceftolozane/tazobactam and to meropenem for complicated intra-abdominal infection (cIAI)

Abstract Background The rising incidence of resistance to currently available antibiotics among pathogens, particularly Gram-negative pathogens, in complicated intra-abdominal infections (cIAIs) has become a challenge for clinicians. Ceftazidime/avibactam (CAZ-AVI) is a fixed-dose antibiotic approved in Europe and the United States for treating (in combination with metronidazole) cIAI in adult hospitalised patients who have limited or no alternative treatment options. The approval was based on the results of RECLAIM, a Phase III, parallel-group, comparative study (RECLAIM 1 [NCT01499290] and RECLAIM 2 [NCT01500239]). The objective of our study was to assess the cost-effectiveness of CAZ-AVI plus metronidazole compared with 1) ceftolozane/tazobactam plus metronidazole and 2) meropenem, as an empiric treatment for the management of cIAI in Italy. Methods A sequential, patient-level simulation model, with a 5-year time horizon and 3% annual discount rate (applied to both costs and health benefits), was developed using Microsoft Excel® to demonstrate the clinical course of the disease. The impact of resistant pathogens was included as an additional factor. Results In the base-case analysis, the CAZ-AVI sequence (CAZ-AVI plus metronidazole followed by a colistin + tigecycline + high-dose meropenem combination after treatment failure), when compared to sequences for ceftolozane/tazobactam (ceftolozane/tazobactam plus metronidazole followed by colistin + tigecycline + high-dose meropenem after treatment failure) and meropenem (meropenem followed by colistin + tigecycline + high-dose meropenem after treatment failure), had better clinical outcomes with higher cure rates (93.04% vs. 91.52%; 92.98% vs. 90.24%, respectively), shorter hospital stays (∆ = − 0.38 and ∆ = − 1.24 days per patient, respectively), and higher quality-adjusted life years (QALYs) gained per patient (4.021 vs. 3.982; 4.019 vs. 3.960, respectively). The incremental cost effectiveness ratio in the CAZ-AVI sequence was €4099 and €15,574 per QALY gained versus each comparator sequence, respectively, well below the willingness-to-pay threshold of €30,000 per QALY accepted in Italy. Conclusions The model results demonstrated that CAZ-AVI plus metronidazole could be a cost-effective alternative when compared with other antibiotic treatment options, as it is expected to provide better clinical benefits in hospitalised patients with cIAI in Italy.

The Impact

Conflicting evidence is currently available concerning the impact on asthma exacerbation of triple inhaled corticosteroid (ICS), long-acting β2-adrenoceptor agonist (LABA), and long-acting muscarinic receptor antagonist (LAMA) fixed-dose combination (FDC). Since meta-analyses allow settling controversies of apparently inconsistent results, we performed a network meta-analysis of Phase III randomised controlled trials including 9535 patients to assess the effect of ICS/LABA/LAMA combinations in uncontrolled asthma. Triple combination therapies with an ICS administered at high dose (HD) were more effective (p<0.05) than medium dose (MD) ICS/LABA/LAMA FDC and both MD and HD ICS/LABA FDCs against moderate to severe exacerbation (relative risk [RR] from 0.61 to 0.80) and increasing trough forced expiratory volume in the 1st second (mL from +33 to +114). Triple combination therapies including HD ICS were superior (p<0.05) than MD ICS/LABA/LAMA FDC in preventing severe exacerbation (RR from 0.46 to 0.65), but not with respect to moderate exacerbation (p>0.05). Triple combination therapies were equally effective on asthma control, with no safety concerns. This quantitative synthesis suggests that ICS/LABA/LAMA FDCs are effective and safe in uncontrolled asthma, and that the dose of ICS in the combination represents the discriminating factor to treat patients with a history of moderate or severe exacerbation.

Abstract Background In a Phase III COMPLEMENT 2 study,ofatumumab(OFA) plusfludarabine(F) and cyclophosphamide (C) demonstrated significantly improved median progression-free survival (PFS) by 54% compared to FC treatment alone (HR=0.67, p=0.0032) in patients with relapsed chronic lymphocytic leukemia (rCLL). However, the relative value of OFA in rCLL has not been formally assessed. The objective of this study was to estimate the incremental cost per (quality-adjusted) life-year of utilizing OFA+FC vs. FC for rCLL in the US. Methods A partition survival model was developed to estimate the expected outcomes and costs of treatment of OFA+FC vs FC forrCLLover a lifetime horizon. The model includes 4 health states: PFS on treatment, PFS off-treatment, post-progression and death. Time during PFS following protocol-defined treatment duration of 6 months, was considered a treatment-free period in the model. Data on PFS, OS and frequencies of adverse events (AEs)were obtained from the Phase III clinical trial for OFA (COMPLEMENT 2). For the extrapolation of OS and PFS a piecewise approach was used, where the efficacy was based on the patient-level data (Kaplan-Meier Survivor Function) until the trial cut-off and a tail extrapolation thereafter (gamma distribution). Health state utilities and dis-utilities for AEs were obtained from previously published vignette studies. Costs incorporated in the model included drug and administration for primary and follow-up therapies, adverse event treatments, medical costs for hospitalizations and physician visits; and end of life costs. The costs were derived from databases (AnalySourceOnline, AHRQ, CMS). Results Treatment with OFA+FC led to an increase of 0.803 life years and 0.543 quality-adjusted life years (QALYs) relative to FC. The total cost of OFA+FC was higher by $6,693 per patient relative to FC. Although addition of AFA to FC lead to higher drug and adverse event costs, these were partially offset by lower follow-up costs compared to FC. The ICER per LY and per QALY gained with OFA+FC vs. FC was $8,333 and $12,322, respectively. Based on probabilistic sensitivity analyses, there wasa85% probability that OFA+FC was cost-effective compared to FC at a societal willingness-to-pay threshold of $100,000 per QALY saved. Conclusions Our analysis suggests treatment with OFA+FC compared to FC is highly cost-effective based Phase 3 within-trial analysis. These results are driven by the improved PFS and OS of OFA+FC vs. FC, as well as the treatment-free period, during which patients experienced PFS without the burden of treatment AEs or costs. Future direct comparisons of OFA+FC versus other treatment options will further clarify the cost-effectiveness of OFA+FC to inform coverage and reimbursement policy decisions.

The Impact

Abstract Background: A central goal of treatment for high-risk AML is enabling patients to receive HCT. CPX-351 is a dual-drug liposomal encapsulation of cytarabine and daunorubicin at a synergistic ratio. A large randomized, open-label, multicenter, phase 3 trial demonstrated superior outcomes, including significantly longer overall survival and a larger fraction of patients reaching HCT, for CPX-351 versus conventional cytarabine/daunorubicin (7+3 regimen) in patients aged 60 to 75 years with newly diagnosed therapy-related AML (tAML) or AML with myelodysplasia-related changes (AML-MRC; Lancet JE, et al. J Clin Oncol. 2018). In order to estimate the cost-effectiveness of treatments for AML, and for CPX-351 in particular, it is necessary to extrapolate survival of patients undergoing HCT to the long-term. The objective of this analysis was to assess the impact of different estimates of post-HCT mortality on cost-effectiveness of CPX-351. Methods: An existing economic model of CPX-351 versus 7+3 for the treatment of tAML or AML-MRC was used to project lifetime health and cost outcomes. The modeled population included 30% patients <60 years of age and 70% between 60 and 75 years of age. The model uses a survival-partition approach, with distinct survival curves for cohorts defined by treatment pathways (response and transplantation). Projected life expectancy for each cohort was estimated based on trial data (for those 60-75 years of age), US population life-tables, and published data. For patients younger than age 60, response rates were adjusted based on published literature. Standardized mortality ratio (SMR) values following HCT were selected individually for the younger and older cohorts. SMR values were calibrated in the model to match the literature finding that post-HCT mortality results in a loss of approximately 30% of life expectancy. This yielded an SMR of 2.25 for older patients and 4.0 for younger patients. Values ranged from 1.0 to 4.0 in sensitivity analyses based on recent appraisals by the United Kingdom's National Institute for Health and Care Excellence (NICE). Model outputs included survival, quality-adjusted life-years (QALYs), costs, and incremental cost-effectiveness ratio (ICER). Results: In the base case with different SMR values by age, the model yielded a predicted ICER value of $111,841/QALY in the overall cohort, which compares favorably to the typical $150,000/QALY threshold (Bae 2014) for good value care in the United States. Using the same estimates of SMR in all patients yielded ICER values of $125,280/QALY and $151,793/QALY for SMR values of 2.25 and 4.0, respectively. Assuming no excess mortality post-HCT relative to the general population, using an SMR of 1.0, resulted in modest improvements in cost-effectiveness (ICER = $102,298/QALY). Conclusions: CPX-351 is a cost-effective option for the treatment of patients with tAML or AML-MRC when accounting for potentially increased mortality following HCT.

Abstract Background: High-dose melphalan 200 mg/m2 (Mel) is the standard for autologous hematopoietic stem cell transplantation (autoHSCT) for multiple myeloma. Retrospective analyses suggested that a combination of busulfan and melphalan (Bu-Mel) may be associated with a longer progression-free survival (PFS). A secondary aim of a randomized, phase III trial that compared the safety and efficacy of Bu-Mel vs Mel was to compare the symptom burden of the two regimens. Symptom burden is the combined impact of disease- and therapy-related symptoms on patient functional ability. Methods: Patients were randomized to Bu-Mel (Bu 130 mg/m2 daily for 4 days, either as a fixed dose or to target an average daily area under the curve of 5000 μmol-min, followed by 2 daily doses of Mel 70 mg/m)2or Mel (Mel 100 mg/m2 daily for 2 days). A subset of patients completed the 20 symptom severity and 6 interference items of MD Anderson Symptom Inventory for Multiple Myeloma (MDASI-MM) prior to the start of the treatment regimen and weekly for 4 weeks post autoHSCT. Symptoms and interference are rated on 0-10 scales (0 = none or no interference, 10 = worst imaginable or complete interference). Differences in individual symptom severity and interference between the two arms were assessed by t-tests and mixed modeling. Results: As previously reported, 204 (Bu-Mel: 104, Mel: 100) were enrolled between October 2011 and March 2017. At last evaluation, 52 (51%) and 49 (49%) patients achieved a CR (p=0.88), and 69 (68%) and 67 (67%) patients achieved a CR+nCR (p=0.88) in Bu-Mel and Mel arms, respectively. Median PFS was 64.7 months and 34.4 months (p=0.013) in Bu-Mel and Mel arms, respectively. There was no difference in OS between the two arms. One hundred sixty-five of the patients (Bu-Mel: 81, Mel: 84) completed at least one MDASI-MM assessment. Median ages at autoHSCT were 57.2 and 57.0 years in Bu-Mel and Mel groups, respectively (p=0.86). At baseline, t-tests showed significantly higher mean severity of constipation (1.80, standard deviation [SD] = 2.87 vs 0.98, SD = 1.94; p=0.036), muscle weakness (2.38, SD=2.49 vs 1.44, SD=1.87; p=0.034), diarrhea (1.45, SD=2.43 vs 0.60, SD=1.10; p=0.005), and global symptom interference (2.96, SD=2.81 vs 1.77, SD=2.00; p=0.003) in the Bu-Mel arm than the Mel arm. The Bu-Mel patients had a significantly higher mean severity of pain (5.67, SD=2.65 vs 3.17, SD=3.07; p=0.0043) and mouth sores (7.35, SD=2.41 vs 1.25, SD=2.22; p <0.0001) than the Mel patients 7 days post autoHSCT. Longitudinal analysis using mixed modeling showed that the Bu-Mel arm had a significantly higher mean severity of pain (ED = 1.102, p=0.003), drowsiness (ED = 0.674, p=0.040), dry mouth (ED = 0.904, p=0.009), constipation (ED = 0.695, p=0.006), muscle weakness (ED = 0.815, p=0.006), mouth sores (ED = 1.683, p <0.0001), rash (ED = 0.362, p=0.019), and interference with physical functions (general activity: ED = 1.015, p=0.010; working: ED=1.229, p=0.006; walking: ED=0.920, p=0.009) than the Mel arm during the 4 weeks following autoHSCT. Conclusions: Patients receiving Bu-Mel vs Mel prior to autoHSCT report some differences in symptom severity, with Bu-Mel patients experiencing more severe sore mouth, pain, and symptom interference with daily functioning. The greater intensity of the double-alkylating agent conditioning regimen of Bu-Mel likely led to these differences. The increased severity of drowsiness, dry mouth, constipation, and muscle weakness may be due to an increased need for opioids to control severe pain and mouth sores. The effect of significant differences in symptom severity and interference at baseline between these two groups, despite randomization, is not clear. However, the longer time to progression of myeloma with the Bu-Mel regimen may offset the greater symptom burden early post autoHSCT. Systematic measurement of symptom burden during clinical trials can provide useful information for clinicians and patients in evaluating the full impact of different treatment regimens and enhance treatment decision making and discussion between clinicians and patients.

The Impact

BACKGROUND: In the United States, implementation of the seven-valent conjugate vaccine into childhood immunization schedules has had an effect on the burden of pneumococcal disease in all ages of the population. To evaluate the impact in Canada, it is essential to have an estimate of the burden of pneumococcal disease before routine use of the vaccine.METHODS: The incidence and costs of pneumococcal disease in the Canadian population in 2001 were estimated from various sources, including published studies, provincial databases and expert opinion.RESULTS: In 2001, there were 565,000 cases of pneumococcal disease in the Canadian population, with invasive infections representing 0.7%, pneumonia 7.5% and acute otitis media 91.8% of cases. There were a total of 3000 deaths, mainly as a result of pneumonia and largely attributable to the population aged 65 years or older. There were 54,330 life-years lost due to pneumococcal disease, and 37,430 quality-adjusted life-years lost due to acute disease, long-term sequelae and deaths. Societal costs were estimated to be $193 million (range $155 to $295 million), with 82% borne by the health system and 18% borne by families. Invasive pneumococcal infections represented 17% of the costs and noninvasive infections represented 83%, with approximately one-half of this proportion attributable to acute otitis media and myringotomy.CONCLUSIONS: The burden of pneumococcal disease before routine use of the pneumococcal conjugate vaccine was substantial in all age groups of the Canadian population. This estimate provides a baseline for further analysis of the direct and indirect impacts of the vaccine.

Purpose Neuroendocrine tumor (NET) progression is associated with deterioration in quality of life (QoL). We assessed the impact of 177Lu-Dotatate treatment on time to deterioration in health-related QoL. Methods The NETTER-1 trial is an international phase III study in patients with midgut NETs. Patients were randomly assigned to treatment with 177Lu-Dotatate versus high-dose octreotide. European Organisation for Research and Treatment of Cancer quality-of-life questionnaires QLQ C-30 and G.I.NET-21 were assessed during the trial to determine the impact of treatment on health-related QoL. Patients completed the questionnaires at baseline and every 12 weeks until tumor progression. QoL scores were converted to a 100-point scale according to European Organisation for Research and Treatment of Cancer instructions, and individual changes from baseline scores were assessed. Time to QoL deterioration (TTD) was defined as the time from random assignment to the first QoL deterioration ≥ 10 points for each patient in the corresponding domain scale. All analyses were conducted on the intention-to-treat population. Patients with no deterioration were censored at the last QoL assessment date. Results TTD was significantly longer in the 177Lu-Dotatate arm (n = 117) versus the control arm (n = 114) for the following domains: global health status (hazard ratio [HR], 0.406), physical functioning (HR, 0.518), role functioning (HR, 0.580), fatigue (HR, 0.621), pain (HR, 0.566), diarrhea (HR, 0.473), disease-related worries (HR, 0.572), and body image (HR, 0.425). Differences in median TTD were clinically significant in several domains: 28.8 months versus 6.1 months for global health status, and 25.2 months versus 11.5 months for physical functioning. Conclusion This analysis from the NETTER-1 phase III study demonstrates that, in addition to improving progression-free survival, 177Lu-Dotatate provides a significant QoL benefit for patients with progressive midgut NETs compared with high-dose octreotide.

The Impact

Severe combined immunodeficiency (SCID) can be detected through newborn bloodspot screening. In the UK, the National Screening Committee (NSC) requires screening programmes to be cost-effective at standard UK thresholds. To assess the cost-effectiveness of SCID screening for the NSC, a decision-tree model with lifetable estimates of outcomes was built. Model structure and parameterisation were informed by systematic review and expert clinical judgment. A public service perspective was used and lifetime costs and quality-adjusted life years (QALYs) were discounted at 3.5%. Probabilistic, one-way sensitivity analyses and an exploratory disbenefit analysis for the identification of non-SCID patients were conducted. Screening for SCID was estimated to result in an incremental cost-effectiveness ratio (ICER) of £18,222 with a reduction in SCID mortality from 8.1 (5–12) to 1.7 (0.6–4.0) cases per year of screening. Results were sensitive to a number of parameters, including the cost of the screening test, the incidence of SCID and the disbenefit to the healthy at birth and false-positive cases. Screening for SCID is likely to be cost-effective at £20,000 per QALY, key uncertainties relate to the impact on false positives and the impact on the identification of children with non-SCID T Cell lymphopenia.

This study evaluated the cost-effectiveness of the consumption of a milk powder product fortified with potassium (+1050.28 mg/day) and phytosterols (+1200 mg/day) to lower systolic blood pressure and low-density lipoprotein cholesterol, respectively, and, therefore, the risk of myocardial infarction (MI) and stroke among the 35–75-year-old population in Malaysia. A Markov model was created against a do-nothing option, from a governmental perspective, and with a time horizon of 40 years. Different data sources, encompassing clinical studies, practice guidelines, grey literature, and statistical yearbooks, were used. Sensitivity analyses were performed to evaluate the impact of uncertainty on the base case estimates. With an incremental cost-effectiveness ratio equal to international dollars (int$) 22,518.03 per quality-adjusted life-years gained, the intervention can be classified as very cost-effective. If adopted nationwide, it would help prevent at least 13,400 MIs, 30,500 strokes, and more than 10,600 and 17,100 MI- and stroke-related deaths. The discounted cost savings generated for the health care system by those who consume the fortified milk powder would amount to int$8.1 per person, corresponding to 0.7% of the total yearly health expenditure per capita. Sensitivity analyses confirmed the robustness of the results. Together with other preventive interventions, the consumption of milk powder fortified with potassium and phytosterols represents a cost-effective strategy to attenuate the rapid increase in cardiovascular burden in Malaysia.

Abstract Study Objectives To examine the cost-effectiveness and potential net monetary benefit (NMB) of a fully automated digital cognitive behavioral therapy (CBT) intervention for insomnia compared with no insomnia treatment in the United States (US). Similar relative comparisons were made for pharmacotherapy and clinician-delivered CBT (individual and group). Methods We simulated a Markov model of 100,000 individuals using parameters calibrated from the literature including direct (treatment) and indirect costs (e.g. insomnia-related healthcare expenditure and lost workplace productivity). Health utility estimates were converted into quality-adjusted life years (QALYs) and one QALY was worth $50,000. Simulated individuals were randomized equally to one of five arms (digital CBT, pharmacotherapy, individual CBT, group CBT, or no insomnia treatment). Sensitivity was assessed by bootstrapping the calibrated parameters. Cost estimates were expressed in 2019 US dollars. Results Digital CBT was cost beneficial when compared with no insomnia treatment and had a positive NMB of $681.06 (per individual over 6 months). Bootstrap sensitivity analysis demonstrated that the NMB was positive in 94.7% of simulations. Relative to other insomnia treatments, digital CBT was the most cost-effective treatment because it generated the smallest incremental cost-effectiveness ratio (−$3,124.73). Conclusions Digital CBT was the most cost-effective insomnia treatment followed by group CBT, pharmacotherapy, and individual CBT. It is financially prudent and beneficial from a societal perspective to utilize automated digital CBT to treat insomnia at a population scale.

IntroductionStereotactic body radiotherapy (SBRT) is a non-invasive alternative to surgery for the treatment of non-metastatic prostate cancer (PC). The objectives of the Novel Integration ofNew prostate radiation schedules with adJuvant Androgen deprivation (NINJA) clinical trial are to compare two emerging SBRT regimens for efficacy with technical substudies focussing on MRI only planning and the use of knowledge-based planning (KBP) to assess radiotherapy plan quality.Methods and analysisEligible patients must have biopsy-proven unfavourable intermediate or favourable high-risk PC, have an Eastern Collaborative Oncology Group (ECOG) performance status 0-1 and provide written informed consent. All patients will receive 6 months in total of androgen deprivation therapy. Patients will be randomised to one of two SBRT regimens. The first will be 40 Gy in five fractions given on alternating days (SBRT monotherapy). The second will be 20 Gy in two fractions given 1 week apart followed 2 weeks later by 36 Gy in 12 fractions given five times per week (virtual high-dose rate boost (HDRB)). The primary efficacy outcome will be biochemical clinical control at 5 years. Secondary endpoints for the initial portion of NINJA look at the transition of centres towards MRI only planning and the impact of KBP on real-time (RT) plan assessment. The first 150 men will demonstrate accrual feasibility as well as addressing the KBP and MRI planning aims, prior to proceeding with total accrual to 472 patients as a phase III randomised controlled trial.Ethics and disseminationNINJA is a multicentre cooperative clinical trial comparing two SBRT regimens for men with PC. It builds on promising results from several single-armed studies, and explores radiation dose escalation in the Virtual HDRB arm. The initial component includes novel technical elements, and will form an important platform set for a definitive phase III study.Trial registration numberANZCTN 12615000223538.
