I've chopped out a few key paragraphs , but it looks like they have an enhanced method for determining the effectiveness and potency of Bex .
Beyond my understanding to be honest , but it looks like they can use this LDL measurement to fine tune Bex efficacy .
And also check it is potent in different stages of manufacture/shelf life .
Also looks like it hints on potential use as a novel treatment for high cholesterol / vascular disease due to what Bex does to the LDLs .
It seems every time they get more data on Bex and Clever-1 , they uncover another important function / use for Bex .
The case for Bex gets stronger and stronger .
Great stuff !
A potency testing is an integral in determining a drug's specific ability or capability to produce a given result.
it has been found that anti-Clever-1 antibodies which specifically bind to certain epitope sequences or at least partly to the certain defined epitope sequences of Clever-1 inhibits and/or blocks modified LDLs, particularly acLDL, uptake efficiently.
The findings of the present invention enable evaluating the biological activity of a therapeutic anti-Clever-1 antibody by determining inhibition and/or blocking uptake of modified low-density lipoprotein, particularly acetylated low-density lipoprotein (acLDL) on Clever-1 presenting cells, and hence the present invention provides a method and an assay for determining a potency of a therapeutic anti-Clever-1 antibody or fragment(s) thereof capable of binding to human Clever-1 and inhibiting its' function.
A method or assay according to the present invention can be used for potency testing of anti-Clever-1 antibodies during product characterization and stability testing.
Further, it is supposed that an anti-Clever-1 antibody binding to the Clever-1 receptor reduces the number of receptors available on the cell surface for modified low-density lipoproteins, such as acLDL, binding and hence preventing macrophage LDL cholesterol uptake and foam cells formation, i.e. the precursor of an atherosclerotic plaque. This has been observed as an increase in free LDL in cell cultures, and an increase in LDL levels of cancer patients treated with an anti-Clever-1 antibody FP-1305. Hence, the findings of the present invention may provide a novel treatment for atherosclerotic cardiovascular disease and thus reduce or even eliminate the development of atherosclerotic plaques caused by macrophages digesting modified LDLs in situation where there is excess LDL. These situations are most commonly referred to as hypercholesterolemia or dyslipidemia.
