Avacta and LG Chem Life Sciences Expand Partnership

Additional drug development programmes utilising Avacta's Affimer® XT technology

Avacta Group plc (AIM: AVCT), the developer of Affimer® biotherapeutics and reagents, is pleased to announce the expansion of its existing multi-target collaboration and development agreement with LG Chem Life Sciences (LG Chem), the life sciences division of the South Korean LG Group, to include new programmes incorporating Avacta's Affimer XTTM serum half-life extension system.

In December 2018, Avacta and LG Chem entered into a multi-target therapeutics development agreement to develop Affimer® therapeutics in several disease areas potentially worth over $300m to Avacta. The companies have today agreed to expand this drug development partnership to include Avacta's Affimer XTTM technology, which can be used to control the time a drug spends in the circulation.

The expansion of the partnership includes an undisclosed additional upfront payment, plus near-term pre-clinical milestones and longer-term clinical development milestones totaling $98.5m for two therapeutics to be developed using the Affimer XT technology. Under the terms of the extended agreement, LG Chem has the exclusive rights to develop and commercialise, on a world-wide basis, Avacta's Affimer PD-L1 inhibitor with Affimer XT serum half-life extension.

The expanded partnership also provides LG Chem with rights to develop and commercialise other Affimer and non-Affimer biotherapeutics combined with Affimer XT half-life extension for a range of indications and Avacta could earn up to $55m in milestone payments for each of these new products. 

In addition, under the agreement Avacta will earn royalties on all future Affimer XT product sales by LG Chem.

Dr. Alastair Smith, Chief Executive of Avacta Group commented:

"I am delighted with this expansion to the agreement with LG Chem, with whom we have developed a strong collaborative partnership. LG Chem is a world-class drug development partner with excellent biologics manufacturing and clinical development capabilities and a pioneering vision to develop innovative therapies.

The expansion of our collaboration to develop new therapies for patients with cancer and other diseases is another strong validation of the Affimer technology and its potential as a therapeutic platform to deliver a pipeline of new drugs.

We look forward to developing these new therapies with our partners, LG Chem, and I look forward to updating the market on this and our other drug development and diagnostics progammes in due course."

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

Avacta is developing novel cancer immunotherapies combining its two proprietary platforms - Affimer® biotherapeutics and pre|CISION™ tumour targeted chemotherapy. With this approach, the Company aims to address the lack of a durable response to current immunotherapies experienced by most patients. The Company's therapeutics development activities are based in Cambridge, UK.

The Company benefits from near-term revenues generated from Affimer reagents for diagnostics, bioprocessing and research, through a separate business unit based in Wetherby, UK.

The Affimer platform is an alternative to antibodies derived from a small human protein. Despite their shortcomings, antibodies currently dominate markets worth in excess of $100bn. Affimer technology has been designed to address many of these negative performance issues, principally: the time taken, and the reliance on an animal's immune response, to generate new antibodies; poor specificity in many cases; large size and cost.

Avacta's pre|CISION targeted chemotherapy platform, releases active chemotherapy only in the tumour, thereby limiting systemic exposure and damage to healthy tissues, and thereby improving the overall safety and therapeutic potential of these powerful anti-cancer treatments.

By combining these two platforms the Company is building a wholly owned pipeline of novel cancer therapies with the aim of creating effective treatments for all cancer patients including those who do not respond to existing immunotherapies. Avacta expects to take its first drug, a pre|CISION targeted form of the standard-of-care Doxorubicin, into the clinic later in 2020 or early 2021.

Avacta has established drug development partnerships with pharma and biotech, including with Moderna Therapeutics Inc., a deal with LG Chem worth up to $310m, a partnership with ADC Therapeutics to develop Affimer drug conjugates and has established a joint venture in South Korea with Daewoong Pharmaceutical focused on cell and gene therapies incorporating Affimer immune-modulators. Avacta actively seeks to license its proprietary platforms in a range of therapeutic areas.

Avacta diagnostics business unit works with partners world-wide to develop Affimers for evaluation by those third parties with the objective of establishing royalty bearing license deals. The Company is also developing a small in-house pipeline of Affimer-based diagnostic assays for licensing.
