CYDY Patent Protection

I've looked into this a little.

New patent protection generally encompasses narrow improvements or new uses for the pharmaceutical not disclosed or suggested in the original patent.

Merck originally developed, patented, and marketed Finasteride for treatment for benign prostate enlargement under the brand name Proscar. Additional patent protection and FDA approval were sought when a new use for Finasteride – treating male pattern baldness – was identified. Finasteride for the treatment of hair loss is marketed under the brand name Propecia.

I think CYDY has the 'new uses' box checked for future patent extensions. If you search the US Patent Records, you'll see CYDY already started with a few uses of Leronlimab already.
