Published Feb 13th 2025
Another patent that sets out how differently the patients can be selected compared to traditional checkpoint inhibitors - as for anti Clever 1 treatment - the total opposite of how the others do it ( In fact according to this - for them ,there is no clear biomarker guidance available to guide treatment ) .
This kind of selection criteria is a major bonus for Faron ,
From the blurb
Currently, immune checkpoint inhibitors targeting CTLA-4 and the PD-1/PD-L1 axis are approved for clinical use, and while highly efficacious in about 10-20% of patients with melanoma and certain other tumors, several other important cancer types (such as prostate, breast and colorectal cancer) remain refractory to them, and there is no clear biomarker available that could differentiate responders from non-responders and guide treatment
83% of patients who have low levels of IFNg and TNF-α are expected to experience clinical benefit when treated with anti-CLEVER-1 antibody bexmarilimab. Further, the likelihood of predicting response to anti-CLEVER-1 antibody bexmarilimab increases to 91%, if classical pro-inflammatory cytokines such as interleukin 6 (IL-6) and/or interleukin 8 (IL-8) are added to the ROC analyses. Also, it has been observed that a standard inflammatory laboratory value C-reactive protein (CRP) has excellent ability to reflect a non-inflammatory cancer type, that is responsive to anti-CLEVER-1 antibody bexmarilimab.
A method for choosing a patient to anti-CLEVER-1 therapy prior to beginning anti-CLEVER-1 therapy using one or several of the inflammatory markers selected from interferon gamma (IFNγ), tumour necrosis factor alpha (TNF-α), interleukin 6 (IL-6), interleukin 8 (IL-8) and C-reactive protein. When the measured level of the inflammatory marker is substantially within the reference values of the inflammatory marker or lower than the average reference value of the inflammatory marker, it is an indication to choose the patient and begin the anti-CLEVER-1 therapy.
