Ascenion and Innovationsstarter Fonds Hamburg acquire equity in Hamburg start-up – innovative therapeutic approach enters clinical testing

Scientists in Hamburg are aiming to improve therapy for HIV patients with a new gene- and cell-based method. At the Hamburg biotech start-up Provirex, they are developing a new therapeutic approach using ‘molecular scissors’ to cut HIV genes out of the genome of infected cells, thus eliminating the virus. This could at last make it possible to remove the virus rather than keeping it in check, as with current forms of treatment. Ascenion GmbH and the Innovationsstarter Fonds Hamburg GmbH have acquired shares in the newly founded company. Provirex will press ahead with the further development of Brec1 recombinase technology, particularly with regard to simpler and more direct forms of drug delivery.

The concept is based on research by Prof. Joachim Hauber and his team at the Heinrich Pette Institute for Experimental Virology and Immunology (HPI) and Prof. Frank Buchholz at the Technische Universität (TU) Dresden. Prof. Buchholz previously worked at the Max Planck Institute of Molecular Cell Biology and Genetics. Together, the scientists have developed and optimized the designer recombinase Brec1 – so-called ‘molecular scissors’. The approach is currently being developed for clinical trials in a collaboration between the HPI and the Medical Center Hamburg-Eppendorf (UKE). The initial evaluation will be in the form of stem-cell therapy in eight HIV patients at the UKE’s stem-cell transplantation clinic, headed by Prof. Nicolaus Kröger. The German Federal Ministry of Education and Research (BMBF), the Senate of Hamburg and ForTra gGmbH für Forschungstransfer of the Else Kröner-Fresenius Foundation are providing grants and investment funds to finance the trial.

Hamburg’s Science Senator, Katharina Fegebank comments: ‘The Hamburg start-up PROVIREX can make a crucial contribution to the fight against HIV and AIDS. The participation of Ascenion and the Innovationsstarter Fonds Hamburg provide an important basis for transferring these research results into application. With this method of therapy developed by the HPI and others, it may be possible for the first time to remove HIV from patient cells precisely and permanently – a historic medical and societal breakthrough on the way to curing HIV and AIDS. The next step is to validate and implement the new therapeutic approach in the clinical trial at the UKE. I thank all those involved for their great commitment, and wish them every success in the development process.’

Michael Westhagemann, Senator for the Economy, Transport and Innovation adds: ‘This is an important sign of hope in the fight against HIV and other currently incurable diseases. I am delighted that this signal is being sent from Hamburg together with other partners, showing that not only do we have excellent research, but through the Innovationsstarter Fonds Hamburg, also provide suitable funding instruments for innovative solutions on their way to the market.’

Ascenion, the HPI’s technology transfer partner, has supported the project intensively from the beginning. ‘We are delighted that the exceptional dedication of all those involved – in basic science, medicine, technology transfer and government – has resulted in the transfer of this promising approach into clinical trials here in Germany,’ says Dr Christian Stein, CEO of Ascenion.

‘This could be a milestone in the fight against HIV,’ adds Prof. Hauber. ‘We are delighted to be developing our promising research results into innovative treatment methods here at the UKE campus in Hamburg.’

Dörte Bunge of the Innovationsstarter Fonds Hamburg GmbH comments: ‘The technology developed by Provirex Genome Editing Therapies GmbH and its affiliated cooperation partners could contribute to a breakthrough in the treatment of HIV and offers significant potential for the successful treatment of other conditions.’
