EGFR expression

Izalontamab brengitecan (Iza-bren; BL-B01D1) is a bispecific ADC targeting EGFR and HER3 that has demonstrated activity in other malignancies. Importantly, tumor tissue obtained at progression after BL-B01D1 treatment confirmed ABCG2 upregulation, validating a clinically relevant resistance mechanism. These findings support BL-B01D1 as a promising therapeutic strategy in mCRPC and nominate ABCG2 as a rational target for overcoming resistance.

Additionally, new therapeutic interventions, such as microbiome-targeted therapies or probiotics, are suggested to enhance the efficacy of ICIs. By uniquely integrating clinical correlations with mechanistic insights on immune microenvironment, this may render pulmonary microbiota to be potential therapeutic strategies for future immunotherapy treatments.

After discontinuing the drug and giving continuous norepinephrine to increase BP, the patient's BP returned to stable. This case suggests that although nimotuzumab-related hypotension is mostly mild and reversible, BP monitoring should still be strengthened to maintain vigilance against severe hypotension and intervene promptly in clinical practice.

Systemic treatment with the EGFR-MMP-MP1 fusion significantly reduced tumor size in MDA-MB-468 xenograft models, confirming in vivo efficacy against cancer cells and acceptable systemic toxicity. We conclude that EGFR-MMP-MP1 peptides represent a novel cancer therapeutic for further development.

The faster mobility of mutation-activated ErbB2 contrasted with the EGF-induced slowing down of its lateral diffusion. In summary, single amino acid substitutions across ErbB2 domains may modulate receptor dynamics, organization, and responsiveness.

Of 52 patients (55.8% female; mean age 64.5 years), 59.6% received chemotherapy and 40.4% received an EGFR TKI as first-line treatment; erlotinib constituted 71.2% of targeted therapies. These results suggest that HER3 expression may warrant further investigation as a candidate biomarker for treatment sequencing decisions and as a potential therapeutic target in EGFR-mutant NSCLC. Prospective studies evaluating chemotherapy-TKI sequencing and HER3-directed agents such as patritumab deruxtecan (HER3-DXd) in HER3-positive patients are needed to confirm these preliminary observations.

PET/CT-derived metabolic parameters, particularly when integrated with artificial intelligence and radiomics, could serve as non-invasive predictors of molecular alterations and help guide individualized treatment strategies. Prospective multicenter studies are warranted to validate these findings and confirm their clinical applicability.

Furthermore, in vivo studies using murine solid tumor models validated the efficacy of both engagers in inhibiting tumor growth. This study demonstrates the potential of DNA origami as a versatile and programmable platform for engineering precision immunotherapies and highlights its utility for targeted tumor eradication.

This study provides the first direct evidence from ex vivo fresh TIL assays using human NSCLC clinical specimens that amivantamab can activate immune responses. EGFR and MET expression may serve as potential biomarkers for amivantamab-induced immune responses.
