About Avacta Group plc - https://www.avacta.com

Avacta Group is a UK-based company focused on improving healthcare outcomes through targeted cancer treatments and diagnostics.

Avacta has two divisions: an oncology biotech division harnessing proprietary therapeutic platforms to develop novel, highly targeted cancer drugs, and a diagnostics division, which is executing on an M&A led growth strategy to create a full-spectrum diagnostics business focused on supporting healthcare professionals and broadening access to testing. Avacta's two proprietary platforms, Affimer® and pre|CISION™ underpin its cancer therapeutics whilst the diagnostics division leverages the Affimer® platform to drive competitive advantage in its markets.

The pre|CISION™ platform modifies chemotherapy to be activated only in the tumour tissue, reducing systemic exposure and toxicity. This is achieved by harnessing an enzyme called FAP which is highly upregulated in most solid tumours compared with healthy tissues, turning chemotherapy into a "precision medicine". The lead pre|CISION™ programme, AVA6000 a tumour activated form of doxorubicin, is in Phase 1 studies and has shown improvement in safety compared with standard doxorubicin, and early signs of clinical activity.

Affimer® is a novel biologic platform which has significant technical and commercial advantages compared with antibodies and is used both to develop advanced immunotherapies and to improve the performance of immunodiagnostics.

With a balanced business and capital allocation model: a high-value oncology pipeline supported by a revenue generating, fast-growing diagnostics business, Avacta seeks to create long-term shareholder value alongside patient benefit.
