Cyclarity (formerly Underdog Pharmaceuticals) published an article on their technology to use Cyclodextrin molecules to encapsulate "toxic biomolecules" including 7-ketocholesterol which they believe is linked to atherosclerosis and macular degeneration. I think this might be the approach they are using with their candidate drug linked above.

I get the impression that Cyclodextrins are far from perfect, but at least there is some hope for non-invasive treatments in future.
