Innovative spray device drives Avectas closer to its goals

The world’s first fully customizable instrument for electrospraying particles supported with prestigious Horizon 2020 win.

With the quality of their innovations endorsed by a prestigious Horizon 2020 win, Avectas is launching the worlds first benchtop instrument for electro-spraying particles. The instrument has been adopted by researchers interested in innovative drug delivery solutions, tissue engineering, textiles, wound healing and electronics.

Irish biotech start-up Avectas has developed a unique instrument to break up fluids and lay down a thin layer of material. The company was founded in 2011 by scientists at Maynooth University with big ambitions: to deliver gene therapy to a patient’s cells without using viruses.

Earlier this year, Avectas, which is supported by national export agency Enterprise Ireland, was awarded $2.3 million under Phase 2 of the SME Instrument to help further develop its technology, which allows for permeable cells to be extracted from a patient, re-engineered to attack cancers, and infused back into the patient.

As it pursued its big ambition, Avectas scientists needed an instrument to break fluids into droplets or particles and lay down a fine layer of material. This led founders Dr. Michael Maguire and Dr. Shirley O’Dea to devise the world’s first fully customizable benchtop instrument – Spraybase – to electrospray particles or electrospin fibers. Over 50 costumer papers using the instrument have already been published.

“It allows precise reproduction of fibers or particles from various materials. It has been shipped around the world,” explains Dr. Gillian Hendy, head of business development at Avectas, whose doctorate was in electrochemistry and drug delivery. More than 170 of the Spraybase instruments have been shipped to customers across over 30 countries. About 80 percent are from academia, 20 percent from industry.

Avectas kicked off sales in Europe after attending an electrospinning conference in London in 2014. Since then, Spraybase has sold well in the UK.

“The two main ways we get sales in Europe are by researchers googling “electrospinning” and coming across our product,” Hendy explains. “And by people hearing about our product from scientific colleagues or reading about the instrument in scientific papers like the paper from University College London.”

The instrument delivers exact volumes and so allows for greater reproducibility in experiments. It has been adopted by those interested in novel drug delivery solutions, tissue engineering, textiles, wound healing, and electronics.”

Avectas has sold Spraybase to customers in France, Germany, Spain, Denmark, Portugal, and Croatia, as well as shipped instruments to Australia, Africa, India, and South America. Avectas has offices in Dublin and Cambridge, Massachusetts in the US, and attracts customers in fields of chemistry, biology, and electronics.

Some research groups are using it to develop fine polymer matrices that are biodegradable when placed in the body; cells can then be placed into these matrices, for regenerative medicine research. Avectas and Spraybase are also part of an EU-funded project on regenerative medicine that involves the University of Maastricht, entitled BONE – Biofabrication of Orthopaedics in a New Era.

“We acquired Spraybase earlier this year and are impressed with it on many levels, including quality, versatility, and ease of use,” notes Prof Jeffery Karp at Brigham and Women’s Hospital, Harvard Medical School in the US. Another satisfied customer is Prof. Conor Buckley of the biomaterials and tissue engineering research group at Trinity College Dublin: “The Spraybase system allows us to fabricate the exact type of particles we need for our research. It’s simple and safe to use, a top priority in our lab.”

Avectas sees their innovative lab instrument, which costs around $20,000, as a way of funding a radical technology in cancer therapy, and specifically CAR-T cell therapy. The CAR-T cell therapy field for cancer shows huge promise and is moving fast. Last year, 2017, saw the first two CAR-T products approved for treating cancer (Novartis and Kite, now owned by Gilead).

In this therapy, immune cells are taken from a cancer patient and genetically tweaked. The cells are delivered back into the patient, where the changes allow them to attack the cancer. Today, viruses are used to deliver the changes but Avectas sees its technology as offering a superior alternative.

Gene therapy is expected to continue to deliver many more innovative cancer therapies and Avectas plans to build a critical component of that mission.

“This is exciting and innovative technology in the gene therapy space,” Dr. Hendy says. “So this is where our R&D is focused. We are aiming to develop this and bring it to market.”

With the Horizon 2020 stamp of approval received by its innovative technology, Avectas is a rising biotech star whose breakthroughs will be central to the developing field of cell therapies.
