Background And Objective: The EV-302 trial found that the combination of enfortumab vedotin (EV) with pembrolizumab significantly improved survival for patients with metastatic urothelial carcinoma (mUC). However, given the high cost of the drugs, there is a need to assess its value by considering both efficacy and cost. This study assessed the cost-effectiveness of EV plus pembrolizumab as a first-line treatment for patients with mUC from the perspective of U.

Background And Objective: China has the highest number of hepatitis C virus (HCV) infections in the world. However, it is unclear what levels of screening and treatment are needed to achieve the WHO 2030 hepatitis C elimination targets. We aimed to evaluate the impact of scaling up interventions on the hepatitis C epidemic and determine how and at what cost these elimination targets could be achieved for the whole population in China.

Objectives: Recently, the IMmotion151 trial evaluated the safety and efficacy of atezolizumab plus bevacizumab in metastatic renal cell carcinoma (mRCC) and found that this combination led to longer progression-free survival. However, no studies have evaluated the cost-effectiveness of atezolizumab plus bevacizumab.

Methods: We constructed a Markov model to evaluate the cost-effectiveness of atezolizumab plus bevacizumab, using costs and utilities from the published studies.

Objective: To determine the cost-effectiveness of imported immune checkpoint inhibitors (ICIs) such as atezolizumab and durvalumab, and domestic ICIs like serplulimab and adebrelimab, in combination with chemotherapy for extensive-stage small cell lung cancer (ES-SCLC) in China.

Methods: Using a 21-day cycle length and a 20-year time horizon, a Markov model was established to compare the clinical and economic outcomes of five first-line ICIs plus chemotherapy versus chemotherapy alone, as well as against each other, from the perspective of the Chinese healthcare system. Transition probabilities were estimated by combining the results of the CAPSTONE-1 trial and a published network meta-analysis.

Rituximab (RTX) is a monoclonal antibody that selectively targets CD20 and is frequently used in the treatment of membranous nephropathy (MN). Analysis of the therapeutic efficacy and safety of RTX in treating MN in practice and a comparative pharmacoeconomic analysis of the RTX and traditional tacrolimus (TAC) regimens can provide valuable insights to aid decision-making by the government and relevant medical insurance departments. We conducted a statistical analysis of medical records from patients diagnosed with MN who underwent RTX treatment between 1 January 2019 and 1 January 2023.

Background: China has one of the highest numbers of liver disease cases in the world, including 6.4 million cirrhosis associated with alcohol-related liver disease (ALD) cases. However, there is still a lack of urgent awareness about the growth of alcohol consumption and the increased burden of ALD in China.

Background: The sustainability and generalizability of China's dynamic zero-COVID strategy on eliminating SARS-CoV-2 transmission has casted doubt globally, mainly because it has exacted high social and economic cost. This study aimed to estimate the disease burden during the first wave of Omicron in China and compared the cost-effectiveness of implementing a Real-world strategy (adjusted dynamic zero-COVID strategy) with two simulated strategies (routine and stricter dynamic zero-COVID strategy) to inform appropriate strategies for COVID-19 pandemic control.

Methods: A dynamic state-transition simulation model was developed to compare the health and cost outcomes between different dynamic zero-COVID strategies.

Background: Oral multikinase inhibitors and immune checkpoint inhibitors (ICIs) are effective for treating advanced hepatocellular carcinoma (aHCC) but may increase cost. This study compared the cost-effectiveness of oral multikinase inhibitors and ICIs in the first-line treatment of patients with aHCC.

Methods: A three-state Markov model was established to study the cost-effectiveness of drug treatment from the perspective of Chinese payers.

Glucocorticoids (GCs) are widely used to treat autoimmune and inflammatory diseases, but recent research has challenged the notion that GCs are universally anti-inflammatory. In this study, we investigated the effects of long-term GC exposure on circulating T cells in a retrospective cohort of 5,476 patients with primary glomerular diseases. Our results revealed that GCs altered the composition pattern of circulating leukocytes and the correlation between circulating lymphocytes and serum cytokines in response to infections, as well as the subsets of CD4 + T cells.

Conventional glucocorticoid (GC) treatment has a long-term influence on T-cell immunity, resulting in an increased risk of opportunistic infection after drug withdrawal. The underlying mechanisms remain ambiguous. This study demonstrated that long-term GC treatment induced persistent lymphopenia in patients with primary glomerular disease.

Article Synopsis
  • Tislelizumab, a domestic PD-1 inhibitor, shows promise as a cost-effective treatment for Chinese patients with driver-negative advanced or metastatic non-small cell lung cancer (NSCLC) in comparison to conventional chemotherapy (docetaxel) and the imported PD-1 inhibitor (nivolumab).
  • A Markov model evaluated the cost-effectiveness of tislelizumab versus these treatments, providing data over a 30-year period by assessing transition probabilities, costs, and health utilities derived from various sources.
  • Results indicated that tislelizumab provided 0.33 more quality-adjusted life-years (QALYs) than docetaxel at a lower cost compared to nivolumab, suggesting that tislel

To investigate whether LY01008, a locally developed bevacizumab biosimilar agent, is appropriate for widespread use among Chinese advanced or recurrent nonsquamous non-small cell lung cancer (NSCLC) patients, our current study was designed to evaluate the cost-effectiveness of first-line LY01008 combined with platinum-doublet chemotherapy versus chemotherapy alone from the perspective of the Chinese healthcare system. This economic evaluation designed a Markov model to compare the healthcare cost and quality-adjusted life-year (QALY) of first-line LY01008 combined with chemotherapy versus first-line chemotherapy. Transition probabilities, including disease progression, survival, and adverse event (AE)-related discontinuation of first-line treatment, were estimated using data from the clinical trials.
