Cost-Effectiveness Analysis of Atezolizumab Versus Chemotherapy as First-Line Treatment for Metastatic Non-Small-Cell Lung Cancer With Different PD-L1 Expression Status

BackgroundAtezolizumab could significantly improve clinical outcomes and was associated with less toxicity compared with chemotherapy as the first-line treatment of PD-L1-selected patients with EGFR and ALK wild-type metastatic non-small-cell lung cancer (NSCLC). However, the economic outcomes remain unclear yet in China. This study aimed to investigate the cost-effectiveness of atezolizumab versus chemotherapy as first-line therapy for metastatic NSCLC with different PD-L1 expression status from the Chinese health sector perspective.MethodsA decision-analytic model was conducted to evaluate the economic outcomes for the first-line treatment of EGFR and ALK wild-type metastatic NSCLC with atezolizumab and chemotherapy in high PD-L1 expression, high or intermediate PD-L1 expression and any PD-L1 expression populations, respectively. The efficacy and safety data were obtained from the IMpower110 trial. Cost and utility values were gathered from the local charges and published literatures. Incremental cost-effectiveness ratio (ICER) was estimated. A scenario analysis for a patient assistance program (PAP) was conducted. One-way and probabilistic sensitivity analyses were performed to explore the robustness of the model results.ResultsAtezolizumab yielded additional 0.91 QALYs, 0.57 QALYs, 0.42 QALYs in comparison with chemotherapy, and the ICERs were $123,778.60/QALY, $142,827.19/QALY, $168,902.66/QALY in the high PD-L1 expression, high or intermediate PD-L1 expression, and any PD-L1 expression populations, respectively. When PAP was available, the ICERs were $52,414.63/QALY, $52,329.73/QALY, $61,189.66/QALY in the three categories of PD-L1 expression status populations, respectively. The ICERs were exceed the willingness-to-pay (WTP) threshold of $30,828/QALY (three times of per capita gross domestic product of China in 2019) in China. One-way sensitivity analyses suggested that the cost of atezolizumab played a vital role in the model outcomes, and the probabilistic sensitivity analyses showed atezolizumab was unlikely to be cost-effective at the WTP threshold regardless of PD-L1 expression status and whether the PAP was available or not.ConclusionsAtezolizumab as first-line treatment for PD-L1-selected metastatic NSCLC patients without EGFR mutations or ALK translocations is unlikely to be cost-effective compared with chemotherapy regardless of PD-L1 expression status in the Chinese context.

6583 Background: The addition of rituximab (RTX) to CVP (cyclophosphamide, vincristine, prednisone) in the treatment of advanced follicular lymphoma increases median time to progression by 17 months (15 month v 32 months; p < 0.0001) (Marcus et al, Blood 2005). A societal cost-effectiveness analysis was performed to estimate projected lifetime clinical and economic implications of this treatment. Methods: The cost-effectiveness (CE) of RTX + CVP versus CVP was estimated for a 50 yr old patient. Kaplan-Meier estimates of progression-free and overall survival, up to 4 years, were obtained from the M39021 trial. After 4 years, transition rates from initiation of treatment to progression or death were assumed to be the same in both arms. The clinical and economic implications of relapse and its treatment were included in the model. Incremental costs associated with addition of RTX were estimated using Medicare reimbursement rates and published retail price data. Costs included drug and administration costs, adverse events, treatment of relapses, and end-of-life costs. Utility estimates were derived from the literature and a 3% discount rate was employed. Results: Projected mean overall survival is 1.5 yrs longer for patients assigned to RTX+ CVP versus only CVP (13.7 v 12.2 yrs). The addition of RTX to CVP is estimated to cost an additional $26,439 on average, with an expected gain of 0.85 year of quality-adjusted survival. Over a lifetime, the cost per QALY gained is $31,329. Sensitivity analyses revealed that the variables that most influenced cost-effectiveness were the time horizon (range: $18,800- $31,240) and the unit drug cost of RTX (range: $24,000-$38,000). Conclusion: The model estimates a cost-to-QALY gained ratio that is below that of many treatments used for oncology patients. The use of RTX + CVP for first-line treatment of advanced follicular lymphoma is projected to be cost-effective compared to CVP alone under a range of sensitivity analyses. No significant financial relationships to disclose.

Background: The aim of this study is to evaluate the pharmacoeconomic profile of adding enzalutamide to first-line treatment for metastatic, hormone-sensitive prostate cancer (mHSPC) from the US and Chinese payers' perspectives.Materials and Methods: A Markov model with three health states: progression-free survival (PFS), progressive disease (PD), and death, was constructed. All patients were assumed to enter the model in the PFS state and transit according to the transition structure. Efficacy data were derived from the ENZAMET trial and Weibull distribution curves were modeled to fit the survival curves. Costs in the model included cost of drugs, best-supportive care (BSC), follow-up, tests, and adverse events (AEs)-related treatments. The primary endpoint of the study was incremental cost-effectiveness ratio (ICER). In addition, the impact of several key parameters on the results of the cost-effectiveness analysis was tested with one-way sensitivity analyses and probabilistic sensitivity analyses.Results: Overall, ICERs were $430,933.95/QALY and $225,444.74/QALY of addition of enzalutamide to androgen deprivation therapy (ADT) vs. ADT from the US and Chinese payers' perspective, respectively. The most influential factors were the utility for the PFS state and the cost of enzalutamide. At the willingness-to-pay (WTP) thresholds of $100,000.00/QALY in the US and $28,988.40/QALY in China, the probability of adding enzalutamide to first-line treatment being a cost-effective option for mHSPC was 0%.Conclusions: Based on the data from the ENZAMET trial and the current price of enzalutamide, adding enzalutamide to first-line treatment is not cost-effective for patients with mHSPC from the US and Chinse payers' perspectives.

Abstract Background：The phase III clinical trial Keynote-604 indicated that pembrolizumab plus chemotherapy could generate clinical benefits in Extensive-Stage Small-Cell Lung Cancer (ES-SCLC). We aim to evaluate the cost-effectiveness of pembrolizumab plus chemotherapy as the first-line treatment of ES-SCLC from the United States (US) payers’ perspective.Methods: A synthetical Markov model was used to evaluate cost and effectiveness of pembrolizumab plus platinum-etoposide (EP) versus EP in first-line therapy for ES-SCLC from the data of Keynote-604. Lifetime costs life-years (LYs), quality adjusted LYs (QALYs), and incremental cost-effectiveness ratios (ICERs) were estimated. One-way and probabilistic sensitivity analyses were performed. In addition, We also considered subgroup cost-effectiveness.Results: Pembrolizumab plus EP resulted in additional 0.18 QALYs (0.32 LYs) and corresponding incremental costs $113,625, resulting an ICER of $647,509 per QALY versus EP. The most influential factor in this model was the cost of pembrolizumab. Probabilistic sensitivity analysis showed there was 0% probability that pembrolizumab combination chemotherapy was cost-effective at willingness-to-pay (WTP) values of $150,000 per QALY in the US. The results of subgroup probabilistic sensitivity analyses suggested that all subgroups were not cost-effective.Conclusion: From the perspective of the US payer, pembrolizumab plus EP is not a cost-effective option as first-line treatment for patients with ES-SCLC at a WTP threshold of $150,000 per QALY.

ObjectivesCetuximab plus leucovorin, fluorouracil and oxaliplatin (FOLFOX-4) is superior to FOLFOX-4 alone as a first-line treatment for patients with metastatic colorectal cancer with RAS wild-type (RAS wt mCRC), with significantly improved survival benefit by TAILOR, an open-label, randomised, multicentre, phase III trial. Nevertheless, the cost-effectiveness of these two regimens remains uncertain. The following study aims to determine whether cetuximab combined with FOLFOX-4 is a cost-effective regimen for patients with specific RAS wt mCRC in China.DesignA cost-effectiveness model combined decision tree and Markov model was built to simulate pateints with RAS wt mCRC based on health states of dead, progressive and stable. The health outcomes from the TAILOR trial and utilities from published data were used respectively. Costs were calculated with reference to the Chinese societal perspective. The robustness of the results was evaluated by univariate and probabilistic sensitivity analyses.ParticipantsThe included patients were newly diagnosed Chinese patients with fully RAS wt mCRC.InterventionsFirst-line treatment with either cetuximab plus FOLFOX-4 or FOLFOX-4.Main outcome measuresThe primary outcomes are costs, quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratios (ICERs).ResultsBaseline analysis disclosed that the QALYs was increased by 0.383 caused by additional cetuximab, while an increase of US$62 947 was observed in relation to FOLFOX-4 chemotherapy. The ICER was US$164 044 per QALY, which exceeded the willingness-to-pay threshold of US$28 106 per QALY.ConclusionsDespite the survival benefit, cetuximab combined with FOLFOX-4 is not a cost-effective treatment for the first-line regime of patients with RAS wt mCRC in China.Trial registration numberTAILOR trial (NCT01228734); Post-results.

e16150 Background: Renal cell carcinoma has increased its incidence by 126% since 1950. A local study developed a complete economic evaluation of sunitinib versus IFN in first-line treatment of mRCC in Colombia, finding that sunitinib was more cost-useful and cost-effective. Methods: A Markov model was developed using 6-week cycles for evaluating the cost-effectiveness of four interventions (IFN, sunitinib, bevacizumab+IFN, sorafenib) approved as first-line treatment for mRCC in Colombia. The model used the third-party payer perspective and a 5-year time-line; it also presumed that all the patients (pts) continued with active treatment until progression when it became acceptable to continue with a second-line treatment or BSC. Overall survival (OS) and progression-free survival (PFS) curves of IFN were used as reference framework; they were obtained form a published clinical trial. The hazard ratios (HR) for PFS and OS were estimated for comparing new generation medicaments with IFN. The information about frequency of use and health service cost units consumed in Colombia was taken from a series of 24 pts treated in Manizales, Pereira, Medellín and Bogotá. Service costs were requested from an external consultant and corresponded to the average value billed by the EPSs, calculated from 33 sources of information which were representative of the country's market. The cost of the medicaments was obtained from LCLC. The costs and benefits were discounted annually at 3%. (all cost are presented in Colombian pesos Col$ 2008 with an exchange rate 1 USD = 1836.20 Col$). Results: Incremental analysis indicated a difference of 41.1 million Col$ in the average total cost of treatment when Sunitinib was compared to IFN; in contrast, comparing sorafenib and Bevacizumab+INF to sunitinib demonstrated that the average total cost was less for the sunitinib by 8.3 and 104.2 million Col$, respectively. Additionally, the ratios of incremental cost-effectiveness by life years (LY) gained demonstrated sunitinib's simple dominance over sorafenib and the combination of bevacizumab+IFN, and an average by LY gained of 100.5 million Col$ compared to IFN. Conclusions: Sunitinib is the most cost-effective option as first-line treatment for mRCC pts in Colombia. [Table: see text]

Background. Doxorubicin/ifosfamide is a first-line systemic chemotherapy for the majority of advanced soft tissue sarcoma (ASTS) subtypes. Trabectedin is indicated for the treatment of ASTS after failure of anthracyclines and/or ifosfamide; however it is being increasingly used off-label as a first-line treatment. This study estimated the cost effectiveness of these two treatments in the first-line management of ASTS in Italy, Spain, and Sweden.Methods. A Markov model was constructed to estimate the cost effectiveness of doxorubicin/ifosfamide compared to trabectedin monotherapy, defined as the cost per QALY gained, in each country.Results. First-line treatment with doxorubicin/ifosfamide resulted in lower two-year healthcare costs and more QALYs than first-line treatment with trabectedin monotherapy in all three countries. Probabilistic sensitivity analysis showed that at a cost per QALY threshold of €35,000, >90% of a cohort would be cost effectively treated with doxorubicin/ifosfamide compared to trabectedin monotherapy in all three countries.Conclusion. Within the model’s limitations, first-line treatment of patients with ASTS with doxorubicin/ifosfamide instead of trabectedin monotherapy affords a cost-effective use of publicly funded healthcare resources in Italy, Spain, and Sweden and is therefore the preferred treatment in all three countries. These findings support the recommendation that trabectedin should remain a second-line treatment.

Abstract Background: Caspofungin was shown to be more effective than fluconazole in treating patients with invasive candidiasis and/or candidaemia (IC/C). However, cost-effectiveness of caspofungin for treating IC/C in Ethiopia remains unknown. We aimed to assess the cost-effectiveness of caspofungin compared to fluconazole as primary treatment of IC/C in Ethiopia.Methods: A Markov cohort model was developed to compare the cost-utility of caspofungin versus fluconazole antifungal agents as first-line treatment for adult inpatients with IC/C from the Ethiopian health system perspective. Treatment outcome was categorized as either a clinical success or failure, with clinical failure being switched to a different antifungal medication. Liposomal amphotericin B (L-AmB) was used as a rescue agent for patients who had failed caspofungin treatment, while caspofungin or L-AmB were used for patients who had failed fluconazole treatment. Primary outcomes were expected quality-adjusted life years (QALYs), costs (US$2021), and the incremental cost-effectiveness ratio (ICER). QALYs and costs were discounted at 3% annually. Cost data was obtained from Addis Ababa hospitals while locally unavailable data were derived from the literature. Cost-effectiveness was assessed against the recommended threshold of 50% of Ethiopia’s gross domestic product/capita. Deterministic and probabilistic sensitivity analyses were conducted to assess the robustness of the findings.Results: In the base-case analysis, treatment of IC/C with caspofungin as first-line treatment resulted in better health outcomes (12.86 QALYs) but higher costs (US$7,714) compared to fluconazole-initiated treatment followed by caspofungin (12.30 QALYs; US$3,217) or L-AmB (10.92 QALYs; US$2,781) as second-line treatment. Caspofungin as primary treatment for IC/C was not cost-effective when compared to fluconazole-initiated therapies. Fluconazole-initiated treatment followed by caspofungin was cost-effective for the treatment of IC/C compared to fluconazole with L-AmB as second-line treatment, at US$316/QALY gained. Our findings were sensitive to medication costs, drug effectiveness, infection recurrence, and infection-related mortality rates. Probabilistic sensitivity analysis confirmed the stability of our findings.Conclusions: Our study showed that the use of caspofungin as primary treatment for IC/C in Ethiopia was not cost-effective when compared with fluconazole-initiated treatment alternatives. The findings supported the use of fluconazole-initiated therapy with caspofungin as a second-line treatment to treat IC/C in Ethiopia and other low-income countries.

133 Background: Adding cetuximab to FOLFIRI chemotherapy (cet+CT) as first-line (1L) treatment for RAS wild-type (wt) metastatic colorectal cancer (mCRC) has been reported as cost-effective vs bevacizumab + FOLFIRI (bev+CT) in multiple jurisdictions. This study determined the cost-effectiveness (CE) of cet+CT for patients with mCRC in China. Methods: A published 3–health-state (nonprogressive, progressive, death) CE model was adapted to reflect Chinese patient characteristics, health state utilities, unit costs, and discounting rates, applying FIRE-3 trial–based resource utilization and adverse event rates. Progression-free and overall survival estimates were based on published FIRE-3 trial simulations to statistically adjust for available later-line treatment modalities in China vs those observed in FIRE-3. [1] Cetuximab and bevacizumab costs were based on up-to-date prices after the 2019 national reimbursement drug listing negotiations. Incremental CE ratios (ICERs) are given as cost (Chinese Yuan [¥]) per life-year (LY) and quality-adjusted LY (QALY) gained. The willingness-to-pay (WTP) threshold was ¥193,931, equivalent to 3 times the gross domestic product per capita, following WHO guidance. Results: Overall costs/costs restricted to 1L treatment were ¥483,771/¥249,619 (cet+CT) and ¥366,036/¥156,802 (bev+CT). Health effects were 3.32/2.68 (cet+CT) and 2.39/1.94 (bev+CT) LYs/QALYs gained. Discounted ICERs for cet+CT vs bev+CT were ¥148,311 and ¥186,517 per LY and QALY gained in deterministic analysis. cet+CT had a 71.8% (LY) and 52.5% (QALY) probability of being cost-effective. Treatment duration with a biologic in 1L, utilities in 3L treatment, and duration of 2L treatment were the main outcome drivers. Conclusions: Projections suggest that cet+CT is cost-effective vs bev+CT for 1L treatment of patients with RAS wt mCRC in China, with ICERs below the current WTP threshold in deterministic and probabilistic sensitivity analyses.

e16088 Background: Recently, several therapies have been approved for treatment of metastatic renal cell carcinoma (mRCC) in the United Kingdom (UK); however, there is scarcity of comparative evidence to assist treatment decisions. We evaluated the cost-effectiveness of pazopanib as first-line treatment of mRCC from a UK National Health Service perspective. Methods: A partitioned-survival analysis model with 3 health states (alive with no progression, alive with progression, or dead) was used to evaluate the cost-effectiveness of pazopanib compared to sunitinib, tivozanib and cabozantinib in treatment-naive mRCC patients with treatment cycle length of 1 week and time horizon of 10 years. The model was populated with clinical effectiveness data obtained from network meta-analysis of pivotal trials and data on costs and utilities collected from UK-specific resources. The key model outcomes were quality-adjusted life years (QALY) and incremental cost-effectiveness ratio (ICER). Probabilistic and one-way sensitivity analyses were performed to test the uncertainty regarding model results. Results: Base-case analysis found that pazopanib was dominant (i.e. less costly and more effective) compared to sunitinib and tivozanib. Pazopanib had lower total costs (£69,861 vs £71,398 and £73,530) and higher QALYs (1.901 vs 1.835 and 1.669, respectively) compared to sunitinib and tivozanib. When compared with cabozantinib, pazopanib was found to be less costly (£174,735 vs £69,861) and less effective (total QALYs, 2.213 vs 1.901, respectively). Results of the probabilistic sensitivity analysis showed that at a willingness-to-pay (WTP) threshold of £30,000 per QALY, the probability of pazopanib being cost-effective was highest as compared to all comparators (84% vs sunitinib, 98% vs tivozanib and 100% vs cabozantinib). One-way sensitivity analysis revealed that effectiveness inputs, time horizon and others are model influencers. Conclusions: Based on a WTP threshold of £30,000/QALY gained, pazopanib is the most cost-effective treatment option compared to sunitinib, tivozanib and cabozantinib, for mRCC patients in UK.

Purpose To assess the cost effectiveness and cost utility of sunitinib malate as a first-line treatment in metastatic renal cell carcinoma (mRCC) compared with interferon-alfa (IFN-α) and interleukin-2 (IL-2) from a US societal perspective. Methods A Markov model was developed to simulate disease progression and to determine progression-free survival, total life-years (LYs), and quality-adjusted life-years (QALYs) gained. Model parameters were derived from the pivotal trial of sunitinib, published literature, government sources, and clinical experts’ opinions. The model included trial-based adverse events (AEs). Costs of drug treatment, routine follow-up, AEs, disease progression, and best supportive care (BSC) of terminally ill patients were included. Results were tested using probabilistic and deterministic sensitivity analyses. Results Treatment with sunitinib is associated with a gain in progression-free years of 0.41 and 0.35 over IFN-α and IL-2. The estimated gains over IFN-α were 0.11 LYs and 0.14 QALYs, and over IL-2 were 0.24 LYs and 0.20 QALYs. Both IFN-α and sunitinib treatments dominate IL-2 treatment; the incremental cost-effectiveness ratio of sunitinib versus IFN-α was $18,611 per progression-free year gained and $67,215 per LY gained, and the cost-utility ratio is $52,593 per QALY gained (at a 5% discount rate). Sensitivity analyses found the results to be most sensitive to utility values during treatment, the cost of sunitinib, and the cost of BSC. Model results were robust to changes in other model variables. Conclusion These results suggest that sunitinib is a cost-effective alternative to IFN-α as a first-line treatment for mRCC.
