lthough emerging immuno-oncology products have been able to elicit unprecedented responses in cancers that are easily accessible to immune cells (eg. leukemia), solid tumors may be resistant to such therapies. 7 Hills is developing cost effective, safe therapeutics to overcome such resistance. Our lead compounds have the potential to increase the antitumor activity of numerous emerging cell-based immunotherapies, and enable the use of recently approved drugs to treat solid tumors that are currently refractory to therapy.

7HP compounds target validated cell adhesion pathways that are critical for T cell homing to specific tissues. They are the only known activators of both the VLA-4/VCAM-1 and LFA-1/ICAM-1 cell adhesion axes. Activation of these adhesion pathways could significantly increase the trafficking of endogenous effector lymphocytes (targets of checkpoint blockade therapeutics) or adoptively transferred effectors (like CAR-T cells) into solid tumors.
Pre-clinical studies have shown that 7HP lead compounds:
Increase the adhesion of activated T-cells to simulated tumor endothelium by 100 fold,
Increase the penetration of activated T-cells into simulated tumor stroma.
