Our Technology: Unlocking Precision Drug Delivery

Our Science and Approach

Why Chemokine Biology?

Chemokines are essential regulators of immune function and cancer progression. However, current therapeutic approaches lack precision, leading to off-target effects and limited efficacy.

XLock is pioneering a new way forward by designing molecules that selectively modulate chemokine activity to address complex disease mechanisms in immunology and oncology.

Precision Engineering

Developing therapies that achieve high specificity in targeting chemokine-driven pathways.

Minimizing Off-Target Effects

Enhancing selectivity to optimize therapeutic potential.

Expanding Possibilities

Unlocking new applications for chemokine-based therapies in oncology and immune disorders.

Our Pipeline: Advancing Novel Drug Delivery Solutions

Pipeline

Advancing a New Class of Precision Therapies

XLock is developing a pipeline of chemokine-targeted therapies designed to address significant gaps in immunology and oncology. Our lead program, XL106, is advancing toward clinical development, with additional programs following closely behind.
