In this work, the two complete complex structures in the protein native state of PD-1 with PD-L1, and the anti-PD-L1 antibody atezolizumab were investigated by atomic force microscopy (AFM) single-molecule force spectroscopy and predicted by AlphaFold modeling...Impact statement Our research developed a novel and close-to-native physiological platform to evaluate protein interactions from structural, mechanical, and kinetic perspectives at the single-molecule level. This could be applied in the design of more effective checkpoint inhibitory molecules and provides relevant methodologies for evaluating single-molecule macromolecular interactions.
She showed a sustained clinical response to fourth-line treatment with the PARP inhibitor olaparib, which lasted 15 months and led to improved performance status. Subsequent progression led to combination therapy with atezolizumab and bevacizumab, maintaining stable disease for eight months. Molecularly guided treatment resulted in an overall survival of 25 months.
The GEMSTONE-303 trial demonstrated that sugemalimab combined with capecitabine and oxaliplatin (CAPOX) improved survival benefit in patients with advanced gastric/gastroesophageal junction cancer (GC/GEJC) and a programmed death-ligand 1 (PD-L1) combined positive score (CPS) ≥5. It is essential to adopt a combination of targeted patient selection, price negotiation, and broader PAP access to bring the ICER below the WTP threshold. These findings inform reimbursement negotiations and highlight the need for stratified pricing strategies to optimize accessibility in economically diverse populations.
