Scientific literature confirms that Netrin-1 is up-regulated in a large variety of cancers:

Anti-cancer effects both as standalone and in combination with chemotherapy or immune checkpoints have been demonstrated during preclinical experiments.

 

Phase I dose escalation met primary safety and tolerability endpoints, but also demonstrated encouraging clinical signs of anti-tumor activity, including prolonged stable disease and objective response.
