- || Review, Journal, PD(L)-1 Biomarker, IO biomarker: Antibody-Drug Conjugates as Novel Therapeutic Agents for Non-Small Cell Lung Carcinoma with or without Alterations in Oncogenic Drivers. (Pubmed Central) - Jul 14, 2024
Several ADCs have already been approved for other cancers, such as breast cancer and urothelial carcinoma. This review summarizes the knowledge about the efficacy and tolerance profiles of ADCs targeting TROP2, HER2, HER3, CEACAM5 and c-MET in metastatic NSCLC with and without alterations in oncogenic drivers.

Review, Journal: New therapeutic target molecules for gastric and gastroesophageal junction cancer. (Pubmed Central) - Apr 17, 2024
Phase III and Ib/III trials of the FGFR2-targeted antibody bemarituzumab for G/GEJ cancer overexpressing FGFR2b are ongoing based on the promising result in a phase II trial, especially in cases with an FGFR2b positivity of???10%...CLDN18.2 is expressed in some G/GEJ tumors but lacks oncogenic driver potential, and the CLDN18.2-targeted antibody zolbetuximab prolonged the survival of CLDN18.2-positive G/GEJ cancer patients in phase III trials...Similarly, targeting of nondriver molecules such as DKK1, TROP2, and CEACAM5 is under investigation in early-stage clinical trials. This shift in focus from target molecules with driver potential to markers for precise drug delivery should increase the number of possible targets in G/GEJ cancer.

- P329G-Engager: A novel universal antibody-based adaptor platform for cancer immunotherapy (Section 3) - Mar 5, 2024 - Abstract #AACR2024AACR_9493;
Neither the individual P329G IgG nor the individual P329G-TCB induced anti-tumoral efficacy, validating the requirement for primary and secondary antibody binding for T cell engaging activity.These results provide in vitro and in vivo evidence that the universal P329G engager platform can be used as an efficacious cancer treatment. Ultimately, this modular approach may enable off-the-shelf personalization via combination of patient-specific antibodies and universal effector cell engagers based on the patient's tumor target and immune profile.

ATOR-4066, a Neo-X-Prime (Section 3) - Mar 5, 2024 - Abstract #AACR2024AACR_8283;
In contrast, RNA-sequencing of peripheral blood in ATOR-4066 treated mice showed only small transcriptomic differences compared to the vehicle treated group, but distinct from mice treated with a CD40 mAb, further demonstrating the CEACAM5 dependent response of ATOR-4066. In summary, these preclinical data demonstrate that ATOR-4066 activates infiltrating myeloid cells resulting in increases in activated tumor infiltrating T cells, thus creating a pro-inflammatory tumor microenvironment, which strongly supports further development and clinical testing of ATOR-4066.

Tusamitamab ravtansine induces immunogenic cell death and synergizes with anti-PD-1 or anti-PD-L1 antibody combination in solid tumor (Section 43) - Mar 5, 2024 - Abstract #AACR2024AACR_5138;
In this model, the combination of tusamitamab ravtansine with anti-PD-1 or anti-PD-L1 antibody led to complete response and, even, tumor-free survivors at 120 days post tumor implantation while single agents were inactive or transiently active. In summary, these preclinical data show that tusamitamab ravtansine could be beneficially combined with immune checkpoint and strongly support their evaluation in clinical development.
