Additional to today's 14:23 & 15:10 posts concerning toxicity generated by ADC therapeutics, - this question and answer from Grok:
Q When ADC therapeutics are used to treat oncology patients, the ADC Linker can cause associated toxicity in the LUNG /LIVER & OCCULAR regions.
Are such LUNG /LIVER/ OCCULAR toxicities fatal?
A Antibody-drug conjugates (ADCs) are a class of targeted cancer therapies that combine monoclonal antibodies with cytotoxic payloads, connected by linkers. While effective, ADCs are associated with toxicities affecting various organs, including the lungs, liver, and eyes, due to both on-target and off-target effects of their payloads and linkers. Below, I address the potential for fatal outcomes related to lung, liver, and ocular toxicities based on available evidence.
Lung Toxicity
Nature of Toxicity: ADCs, such as trastuzumab deruxtecan, enfortumab vedotin, and others, are associated with interstitial lung disease (ILD) or pneumonitis, which can be severe. A meta-analysis indicates pneumonitis is the most common cause of death associated with ADCs, with incidence rates varying (e.g., 13.6% for trastuzumab deruxtecan, 28% for enfortumab vedotin, 3.2% for brentuximab vedotin). Fatal cases, though rare, have been reported, particularly with trastuzumab emtansine and tisotumab vedotin (incidence
