How It Works
An antibody fragment is attached to a DNA-like molecule (MORF1) to create a targeting scaffold (Fab’-MORF1).
Fab‘-MORF1 is injected into the bloodstream to bind the target receptor on the malfunctioning cell.
A polymer is attached to multiple MORF2s (P-MORF2). MORF2 is complementary to MORF1.
P-MORF2 is injected into the bloodstream and attaches to multiple Fab’-MORF1 at the cell surface. This causes target receptors to crosslink. Binding of P-MORF2 to Fab’-MORF1 is the therapeutically active step. Fab'-MORF1 can be premixed with P-MORF2 prior to administration, if required.
We can crosslink more than 10 receptors with greater efficacy resulting from more crosslinking. Multiple mouse studies have shown long term, curative survival. (Tested in xenograft SCID mice targeting CD20 in Raji cells.)
Crosslinking of cell receptors sends a signal downstream to engage pathways within the cell. These signals can cause cell suicide or immune system activation.
