Balixafortide

How it works

Blocks CXCR4, a receptor that holds cells in place, meant to pull breast cancer cells out of hiding and into chemo's path.

What it's made of

A designed peptide closed into a ring (a macrocycle that mimics a hairpin), from Polyphor's platform. It blocks the CXCR4 receptor, the same one as motixafortide.

What it's for

Prescribed for

Nothing.

Sold as

“Draw the tumor out of its hiding place so the chemo reaches it better.”
