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

Avacta Group is developing novel cancer immunotherapies and powerful diagnostics based on its two proprietary platforms - Affimer® biologics and pre|CISION™ tumour targeted chemotherapies.

The Affimer® platform is an alternative to antibodies and is derived from a small human protein. Affimer® technology has been designed to address many of the negative issues of antibodies, principally: the time taken to generate new antibodies, the reliance on an animal's immune response; poor specificity in many cases; in addition to, the complexity and high cost of manufacture. Despite these shortcomings, antibodies currently dominate markets, such as diagnostics and therapeutics, which are worth in excess of $100bn.

Avacta's pre|CISION™ targeted chemotherapy platform is designed to selectively release active chemotherapy in FAP rich tumour tissue to limit the systemic exposure that causes damage to healthy tissues, and thereby aims to improve the overall safety and therapeutic potential of these powerful anti-cancer treatments.

The Avacta Group comprises two divisions: The therapeutics development activities are based in London and Cambridge, UK and a separate diagnostics business unit is based in Wetherby, UK. The Group is generating near-term revenues from Affimer® reagents for diagnostics, bioprocessing and research.

Avacta's Diagnostics Division is developing an in-house pipeline of Affimer-based diagnostic assays, including the AffiDX® SARS-CoV-2 Lateral Flow Rapid Antigen Test, and works with partners world-wide to develop bespoke Affimer® reagents for third party products.

Avacta's Therapeutics Division is working to generate more tolerable and durable treatments for oncology patients who do not respond to existing therapies. By combining its two proprietary platforms the Group is building a wholly owned pipeline of clinically differentiated cancer therapies. In 2021 Avacta transitioned to become a clinical stage biopharmaceutical company, when it commenced a phase I trial in patients with locally advanced or metastatic selected solid tumours. The study was a first-in-human, open label, dose-escalation and expansion study of the Group's lead pre|CISION™ prodrug, AVA6000 (a pro-doxorubicin).

Avacta has established drug development partnerships with pharma and biotech, including a multi-target deal with LG Chem worth up to $400m, a joint venture in South Korea with Daewoong Pharmaceutical focused on cell and gene therapies incorporating Affimer® immune-modulators and a recent license agreement with Point Biopharma for them to develop radiopharmaceuticals based on the pre|CISION™ platform.
