Our Adenovo™ platform and 100‑million‑variant library move us from discovery to impact. With THEO‑260 as our lead programme, our world‑class team is applying world‑leading science to expand access to innovative therapies that promise lasting benefit.

The Problem

The barrier to effective therapies in solid tumours

In many advanced cancers, tumour cells are protected by a dense and complex microenvironment, including cancer‑associated fibroblast or CAFs.

This barrier limits drug delivery, suppresses immune response and enables disease progression — reducing the effectiveness of both targeted therapies and immunotherapies.

The Solution

Evolved to overcome the tumour microenvironment

Theolytics is developing systemically deliverable immunotherapies based on oncolytic adenoviruses designed to break through the barriers of solid tumours.

Using our Adenovo™ platform, we identify viral candidates capable of selectively targeting and destroying both cancer cells and the surrounding tumour‑supporting stroma- enabling a more complete and clinically meaningful therapeutic response.

From Library to Life

Rational discovery meets translational precision

Our Adenovo platform screens vast libraries of adenovirus variants in clinically relevant human systems to identify candidates with real‑world therapeutic potential.

By prioritising attributes such as tumour selectivity, systemic delivery and immune activation, we evolve therapies designed for optimal clinical performance, not just laboratory success.

Advancing oncolytic immunotherapy

Since our founding, we’ve continually expanded our discovery platform, progressed multiple therapeutic programmes, and secured the investment and partnerships needed to bring innovative treatments closer to patients.
