#### Ivonescimab plus chemotherapy versus chemotherapy in EGFR-mutated nonsquamous NSCLC after EGFR TKI therapy, China: Long et al. (2025)

Relevance: Evaluates ivonescimab plus chemotherapy against chemotherapy alone in EGFR-mutated nonsquamous non-small-cell lung cancer from the perspective of the Chinese healthcare system, the cost-effectiveness analysis by Long et al. summarized in section 4.1.

> “This investigation systematically analyzed the cost-effectiveness of treating advanced/metastatic nsq-NSCLC with EGFR mutations with a combination of ivonescimab and chemotherapy from the standpoint of the Chinese healthcare system.”
> “A decision-embedded Markov model with three specific health states was established for predicting the economic and health outcomes associated with ivonescimab plus chemotherapy or chemotherapy alone over a 10-year time frame.”
> “Additionally, a 5% discount was applied annually to medical benefits and costs”
> “Relative to the use of chemotherapy alone, the combination of chemotherapy with ivonescimab resulted in an additional 0.13 QALY (0.17 LYs) with a marginal cost of $35,166 and an ICER of $277,594 per additional QALY, which far exceeded the pre-set WTP threshold of $36,997/QALY.”
> “In the PSA, all ICER scatter points in the cost-effectiveness scatter plot fell above the WTP threshold, indicating that at a WTP cutoff of $36,997 per QALY, the probability that ivonescimab-chemotherapy treatment is cost-effective compared to chemotherapy alone was 0%”

#### First-line or second-line osimertinib versus first-generation EGFR TKI followed by chemotherapy in newly diagnosed EGFR-mutated advanced NSCLC, United States and China: Wu et al. (2019)

Relevance: Evaluates first-line and second-line osimertinib against standard first-generation EGFR-TKI therapy in newly diagnosed EGFR-mutated advanced non-small-cell lung cancer from a public payer perspective in the United States and China, the treatment sequence that leads to the post-TKI setting of HARMONi.

> “The objective of this study was to assess cost and effectiveness of osimertinib in treating newly diagnosed advanced non‐small cell lung cancer with an epidermal growth factor receptor (EGFR) mutation from a public payer's perspective in the U.S. and China.”
> “Markov models were developed to compare three treatment strategies: first‐line use of osimertinib, first‐line use of the standard first‐generation EGFR‐tyrosine kinase inhibitor (EGFR‐TKI) followed by the second‐line use of osimertinib, and the standard first‐generation EGFR‐TKI therapy (standard care [SOC]).”
> “Therefore, we used a 10‐year time horizon in the base‐case analysis and varied the time horizon from 1 to 20 years in the sensitivity analyses.”
> “In the base‐case analysis, both costs and QALYs were discounted 3% and 5% annually in the U.S. [33] and China [34], respectively.”
> “For the whole population in the U.S., the mean costs and QALYs associated with the first‐line osimertinib, second‐line osimertinib, and SOC strategies were $511,415 and 2.316, $330,602 and 1.766, and $244,837 and 1.465, respectively.”
> “The corresponding numbers in China were $72,615 and 2.244, $51,658 and 1.757, and $41,159 and 1.487”
> “The resultant ICERs for first‐line osimertinib versus SOC were $312,903 in the U.S. and $41,512 in China.”
> “The ICERs for second‐line osimertinib versus SOC were $284,532 in the U.S. and $38,860 in China.”
> “The probability of the SOC strategy being cost‐effective is 1.0 if the willingness to pay threshold is below $150,000/QALY in the U.S. and below $30,000/QALY in China.”

#### Utility weights by treatment response and progression status, EGFR T790M-positive NSCLC after EGFR TKI therapy: Bertranou et al. (2018)

Relevance: EQ-5D utilities valued with UK tariffs by treatment response and progression status in EGFR T790M-positive non-small-cell lung cancer after EGFR-TKI therapy.

Access: Free full text

Not quoted: The scenario utility weights by treatment response and EQ-5D valuation set are reported in Table 3 of the full text, which this page does not quote.

> “For progression-free and progressed disease, utility values were derived from EQ-5D patient-level data collected in the AURA2 (5-level questionnaire) and IMPRESS (3-level questionnaire) studies.”
> “Utilities were calculated applying the EQ-5D-5L crosswalk index values”
> “The weighted progression-free utility values are 0.805 and 0.778, respectively.”
> “The mean progressed disease utility value is 0.715 (SD = 0.029).”
> “Utility decrements associated with adverse events were sourced from a study by Nafees et al.”

#### Utility weights for progression-free and progressive disease on EGFR TKI, chemotherapy or immunotherapy, and best supportive care, EGFR-mutant advanced NSCLC: Ezeife et al. (2018)

Relevance: Utilities for progression-free disease on an EGFR-TKI, progressive disease on an EGFR-TKI or on chemotherapy or immunotherapy, and best supportive care in EGFR-mutant advanced non-small-cell lung cancer.

Access: Not open access

Not quoted: The utility weights are reported in the full text, which this page does not quote.

> “A Markov model was developed to project the outcomes and direct medical costs of initial treatment with osimertinib or current standard-of-care (SoC) EGFR TKIs, gefinitib or afatinib, in patients with previously untreated EGFR-mutant advanced NSCLC.”
> “Model outcomes included costs (in 2018 Canadian dollars), life years (LYs), quality-adjusted life-years (QALYs), and the cost utility of osimertinib compared to SoC EGFR TKI, or incremental cost per QALY gained.”
