Cost-effectiveness of treating advanced melanoma with tumor-infiltrating lymphocytes based on an international randomized phase 3 clinical trial
INTRODUCTION: In a multicenter, open-label randomized phase 3 clinical trial conducted in the Netherlands and Denmark, treatment with ex vivo-expanded tumor-infiltrating lymphocytes (TIL-NKI/CCIT) from autologous melanoma tumor compared with ipilimumab improved progression-free survival in patients with unresectable stage IIIC-IV melanoma after failure of first-line or second-line treatment. Based on this trial, we conducted a cost-utility analysis. METHODS: A Markov decision model was constructed to estimate expected costs (expressed in 2021€) and outcomes (quality-adjusted life years (QALYs)) of TIL-NKI/CCIT versus ipilimumab in the Netherlands. The Danish setting was assessed in a scenario analysis. A modified societal perspective was applied over a lifetime horizon. TIL-NKI/CCIT production costs were estimated via activity-based costing. Through sensitivity analyses, uncertainties and their impact on the incremental cost-effectiveness ratio (ICER) were assessed. RESULTS: Mean total undiscounted lifetime benefits were 4.47 life years (LYs) and 3.52 QALYs for TIL-NKI/CCIT and 3.33 LYs and 2.46 QALYs for ipilimumab. Total lifetime undiscounted costs in the Netherlands were €347,168 for TIL-NKI/CCIT (including €67,547 for production costs) compared with €433,634 for ipilimumab. Undiscounted lifetime cost in the Danish scenario were €337,309 and €436,135, respectively. This resulted in a dominant situation for TIL-NKI/CCIT compared with ipilimumab in both countries, meaning incremental QALYs were gained at lower costs. Survival probabilities, and utility in progressive disease affected the ICER most. CONCLUSION: Based on the data of a randomized phase 3 trial, treatment with TIL-NKI/CCIT in patients with unresectable stage IIIC-IV melanoma is cost-effective and cost-saving, both in the current Dutch and Danish setting. These findings led to inclusion of TIL-NKI/CCIT as insured care and treatment guidelines. Publicly funded development of the TIL-NKI/CCIT cell therapy shows realistic promise to further explore development of effective personalized treatment while warranting economic sustainability of healthcare systems.</p
Micro-costing diagnostics in oncology:from single-gene testing to whole- genome sequencing
Purpose: Predictive diagnostics play an increasingly important role in personalized medicine for cancer treatment. Whole-genome sequencing (WGS)-based treatment selection is expected to rapidly increase worldwide. This study aimed to calculate and compare the total cost of currently used diagnostic techniques and of WGS in treatment of non-small cell lung carcinoma (NSCLC), melanoma, colorectal cancer (CRC), and gastrointestinal stromal tumor (GIST) in the Netherlands. Methods: The activity-based costing (ABC) method was conducted to calculate total cost of included diagnostic techniques based on data provided by Dutch pathology laboratories and the Dutch-centralized cancer WGS facility. Costs were allocated to four categories: capital costs, maintenance costs, software costs, and operational costs. Results: The total cost per cancer patient per technique varied from € 58 (Sanger sequencing, three amplicons) to € 2925 (paired tumor-normal WGS). The operational costs accounted for the vast majority (over 90%) of the total per cancer patient technique costs. Conclusion: This study outlined in detail all costing aspects and cost prices of current and new diagnostic modalities used in treatment of NSCLC, melanoma, CRC, and GIST in the Netherlands. Detailed cost differences and value comparisons between these diagnostic techniques enable future economic evaluations to support decision-making
Multi-omic analysis identifies hypoalbuminemia as independent biomarker of poor outcome upon PD-1 blockade in metastatic melanoma
We evaluated the prognostic value of hypoalbuminemia in context of various biomarkers at baseline, including clinical, genomic, transcriptomic, and blood-based markers, in patients with metastatic melanoma treated with anti-PD-1 monotherapy or anti-PD-1/anti-CTLA-4 combination therapy (n = 178). An independent validation cohort (n = 79) was used to validate the performance of hypoalbuminemia compared to serum LDH (lactate dehydrogenase) levels. Pre-treatment hypoalbuminemia emerged as the strongest predictor of poor outcome for both OS (HR = 4.01, 95% CI 2.10–7.67, Cox P = 2.63e−05) and PFS (HR = 3.72, 95% CI 2.06–6.73, Cox P = 1.38e−05) in univariate analysis. In multivariate analysis, the association of hypoalbuminemia with PFS was independent of serum LDH, IFN-γ signature expression, TMB, age, ECOG PS, treatment line, treatment type (combination or monotherapy), brain and liver metastasis (HR = 2.76, 95% CI 1.24–6.13, Cox P = 0.0131). Our validation cohort confirmed the prognostic power of hypoalbuminemia for OS (HR = 1.98, 95% CI 1.16–3.38; Cox P = 0.0127) and was complementary to serum LDH in analyses for both OS (LDH-adjusted HR = 2.12, 95% CI 1.2–3.72, Cox P = 0.00925) and PFS (LDH-adjusted HR = 1.91, 95% CI 1.08–3.38, Cox P = 0.0261). In conclusion, pretreatment hypoalbuminemia was a powerful predictor of outcome in ICI in melanoma and showed remarkable complementarity to previously established biomarkers, including high LDH.</p

Molecular Profiling Is Rather Likely to Be Cost Effective
In a recent report, Bonastre et al1 calculated the cost effectiveness of molecular profiling for adjuvant decision making in patients with node-negative breast cancer and concluded that, under the present circumstances in France, the 70-gene signature (MammaPrint) is unlikely to be cost effective
Head-to-head comparison of the 70-gene signature versus the 21-gene assay: cost-effectiveness and the effect of compliance
Both the 70-gene signature and the 21-gene assay are novel prognostic tests used to guide adjuvant chemotherapy decisions in patients with early breast cancer. Although the results of ongoing prospective trials will only become available in some years, the tests have already been included in clinical guidelines such as St. Gallen’s. In literature, the cost-effectiveness (CE) of both tests as compared to conventional prognostic tests has been described. We report on a direct comparison of CE; as different compliance rates were reported, we also taken these into account. A Markov decision model with a time horizon of 20 years was developed to assess the effects, costs and CE of three alternatives; 21-gene, 70-gene, and St. Gallen (SG) or Adjuvant Online (AO), dependent on the dataset used in patients with early, node-negative, breast cancer. Sensitivity and specificity were based on two datasets, incorporating compliances rates based on literature. For both datasets, whereas the 70-gene signature yielded more quality adjusted life years (QALYs) and was less costly; the 21-gene amounted more life years (LYs) but was more costly. The decision uncertainty surrounding the probability of CE of the Thomassen-series amounted 55% for both cost/LY and cost/QALY, for the Fan-series 80% for LY and 65% for QALYs. Taking reported compliance with discordant test results into account, in general, the effect of all strategies decreased, while the costs increased, without relatively influencing the CEA performance. This comparison indicates that the performances of the 70-gene and the 21-gene based on reported studies are close. The 21-gene has the highest probability of being cost-effective when focusing on cost/LY, while focusing on cost/QALY, the 70-gene signature was most cost-effective. The level of compliance can have serious impact on the CE. With additional data, preferably from head-to-head outcome studies and especially on compliance concerning discordant test results, calculations can be made with higher degrees of certainty
Early stage cost-effectiveness analysis of a BRCA1-like test to detect triple negative breast cancers responsive to high dose alkylating chemotherapy
Purpose
Triple negative breast cancers (TNBC) with a BRCA1-like profile may benefit from high dose alkylating chemotherapy (HDAC). This study examines whether BRCA1-like testing to target effective HDAC in TNBC patients can be more cost-effective than treating all patients with standard chemotherapy. Additionally, we estimated the minimum required prevalence of BRCA1-like and the required positive predictive value (PPV) for a BRCA1-like test to become cost-effective.
Methods
Our Markov model compared 1) the incremental costs; 2) the incremental number of respondents; 3) the incremental number of Quality Adjusted Life Years (QALYs); and 4) the incremental cost-effectiveness ratio (ICER) of treating TNBC women with personalized HDAC based on BRCA1-like testing vs. standard chemotherapy, from a Dutch societal perspective and a 20-year time horizon, using probabilistic sensitivity analysis. Furthermore, we performed one-way sensitivity analysis (SA) to all model parameters, and two-way SA to prevalence and PPV. Data were obtained from a current trial (NCT01057069), published literature and expert opinions.
Results
BRCA1-like testing to target effective HDAC would presently not be cost-effective at a willingness-to-pay threshold of €80.000/QALY (€81.981/QALY). SAs show that PPV drives the ICER changes. Lower bounds for the prevalence and the PPV were found to be 58.5% and 73.0% respectively.
Conclusion
BRCA1-like testing to target effective HDAC treatment in TNBC patients is currently not cost-effective at a willingness-to-pay of €80.000/QALY, but it can be when a minimum PPV of 73% is obtained in clinical practice. This information can help test developers and clinicians in decisions on further research and development of BRCA1-like tests
A cost-effectiveness analysis of using TheraBite in a preventive exercise program for patients with advanced head and neck cancer treated with concomitant chemo-radiotherapy
Previous studies have shown that a “Preventive Exercise Program” (PREP) is cost-effective compared to the standard exercise program provided in “Usual Care” (UC) in patients with advanced head and neck cancer. The current paper specifically estimates the cost-effectiveness of the TheraBite jaw rehabilitation device (TB) which is used as part of the PREP, compared to Speech Language Pathology (SLP) sessions as part of UC, and herewith intents to inform reimbursement discussions regarding the TheraBite device. Costs and outcomes [quality-adjusted life-years (QALYs)] of the TB compared to SLP were estimated using a Markov model of advanced head and neck cancer patients. Secondary outcome variables were trismus, feeding substitutes, facial pain, and pneumonia. The incremental cost-effectiveness ratio (ICER) was estimated from a health care perspective of the Netherlands, with a time horizon of 2 years. The total health care costs per patient were estimated to amount to €5,129 for the TB strategy and €6,915 for the SLP strategy. Based on the current data, the TB strategy yielded more quality-adjusted life-years (1.28) compared to the SLP strategy (1.24). Thus, the TB strategy seems more effective (+0.04) and less costly (−€1,786) than the SLP only strategy. At the prevailing threshold of €20,000/QALY the probability for the TB strategy being cost-effective compared to SLP was 70 %. To conclude, analysis of presently available data indicates that TB is expected to be cost-effective compared to SLP in a preventive exercise program for concomitant chemo-radiotherapy for advanced head and neck cancer patients
Cost-effectiveness of heat and moisture exchangers compared to usual care for pulmonary rehabilitation after total laryngectomy in Poland
The beneficial physical and psychosocial effects of heat and moisture exchangers (HMEs) for pulmonary rehabilitation of laryngectomy patients are well evidenced. However, cost-effectiveness in terms of costs per additional quality-adjusted life years (QALYs) has not yet been investigated. Therefore, a model-based cost-effectiveness analysis of using HMEs versus usual care (UC) (including stoma covers, suction system and/or external humidifier) for patients after laryngectomy was performed. Primary outcomes were costs, QALYs and incremental cost-effectiveness ratio (ICER). Secondary outcomes were pulmonary infections, and sleeping problems. The analysis was performed from a health care perspective of Poland, using a time horizon of 10 years and cycle length of 1 year. Transition probabilities were derived from various sources, amongst others a Polish randomized clinical trial. Quality of life data was derived from an Italian study on similar patients. Data on frequencies and mortality-related tracheobronchitis and/or pneumonia were derived from a Europe-wide survey amongst head and neck cancer experts. Substantial differences in quality-adjusted survival between the use of HMEs (3.63 QALYs) versus UC (2.95 QALYs) were observed. Total health care costs/patient were 39,553 PLN (9465 Euro) for the HME strategy and 4889 PLN (1168 Euro) for the UC strategy. HME use resulted in fewer pulmonary infections, and less sleeping problems. We could conclude that given the Polish threshold of 99,000 PLN/QALY, using HMEs is cost-effective compared to UC, resulting in 51,326 PLN/QALY (12,264 Euro/QALY) gained for patients after total laryngectomy. For the hospital period alone (2 weeks), HMEs were cost-saving: less costly and more effective
H-TArget model: Early technology assessment for ext generation sequencing in oncology
Background:
Next Generation Sequencing (NGS) promises to find mutations (targets) in individual cancer patients, to subsequently prescribe targeted therapy. Currently, NGS is in development, the effects on choice of therapy and prognosis are still unclear, and the costs for targeted therapies are high. To accelerate the reimbursement process of NGS and potential new targeted therapies, and have a NGS-panel available for patients in the earliest possible stage, early Technology Assessment (TA) is performed to inform policy making around NGS in the Netherlands. One of the aims of the TA was to conduct a cost-effectiveness analysis.
Methods:
We constructed a target-based decision model (H-TArget) to estimate the cost-effectiveness of NGS versus single- and no testing. Standard- and targeted therapies in first and second line for 9 targets (BRAF, KRAS, NRAS, EGFR, ERBB/HER, MET, ROS, ALK, RET) over 3 tumor types (melanoma, non-small-cell lung cancer (NSCLC), colorectal cancer (CRC)) were incorporated. A Dutch healthcare perspective and a 5-year time horizon were adopted. Outcomes were incremental cost-effectiveness ratios (ICER) expressed in {euro}/quality adjusted life year (QALY). The threshold for cost-effectiveness is 80k in the Netherlands, which means that the concerning technology is cost-effective if the ICER is below this threshold. Expected Value of Partial Perfect Information (EVP(P)I) was calculated to quantify the value of further research into particular subsets of uncertain parameters.
Results:
The expected ICER was {euro}65k/QALY for melanoma, {euro}188k/QALY for NSCLC, and {euro}103k/QALY for CRC. As a weighted average to the three populations, the overall ICER yielded {euro}160k/QALY. The EVPI was {euro}25M for melanoma, the subsets of parameters to focus on in future research were: {euro}2M together for failures, prevalence, survival, and {euro}23M for costs. Conclusions:
At the moment, using NGS is only cost-effective for melanoma. This is mostly due to the high costs of targeted therapies and the fact that the effects are still small. Based on our findings, industry should strive for a significant cost reduction of targeted therapies or achieve a spectacular improvement in effectiveness, which could improve the cost-effectiveness
