Abstract
Background
With the increasing use of novel targeted drugs and immune checkpoint inhibitors (ICIs) for lung cancer (LC), the life expectancy of patients with LC has notably increased. In China, many drugs with the same mechanism of action have been approved by the National Medical Products Administration (NMPA) through phase III randomized controlled trials (RCTs). However, differences occur in these drugs’ efficacy and adverse effects, all of which have been compared with standard treatments, and data from head-to-head studies are lacking.
Methods
The key RCTs of EGFR tyrosine kinase inhibitors (EGFR-TKIs), ALK-TKIs, and ICIs approved by NMPA in advanced LC in China were searched and divided into five groups. The American Society of Clinical Oncology Value Framework (ASCO-VF v2) and European Society for Medical Oncology Magnitude of Clinical Benefit Scale (ESMO-MCBS v1.1) were used to evaluate the net health benefits (NHB) of RCTs, including efficacy, adverse reactions, and patient-reported outcomes (PROs), etc. The consistency of the ASCO-VF and ESMO-MCBS was compared.
Results
As of September 2024, 37 RCTs have been included in the ASCO-VF and ESMO-MCBS. NHB scores ranged from 12.30 to 93.25. Nineteen trials met the ASCO-VF “substantial benefit”, and 28 trials achieved the ESMO-MCBS “substantial benefit”. Except for icotinib, dacomitinib, and befotertinib, all EGFR-TKIs and ALK-TKIs met the threshold of two frameworks. In the ICI regimens, eight regimens met the threshold of “ substantial benefit ” as defined by the two frameworks and nine studies showed conflicting results. The correlation coefficient of the 37 pairs of scores in the advanced LC study was estimated to be 0.473(Spearman), and the consistency analysis showed fair agreement.(κ = 0.265, p = 0.001).
Conclusions
ASCO-VF and ESMO-MCBS focus on clinical efficacy and consider the adverse effects of drugs and PROs. We look forward to head-to-head studies on the different treatment options and advocate refining the ESMO-MCBS.
