Laborjournal on Seamless Therapeutics

In their news article in Laborjournal, the Dresden-based start-up Seamless Therapeutics reflects on programmable recombinases that operate independently of the cell's own DNA repair system and could thus in future make it possible to cure the disease haemophilia A, for which currently merely the symptoms are treated.

Frank Buchholz is a founding member of the start-up and head of the Medical Systems Biology research group at the Faculty of Medicine Carl Gustav Carus of TU Dresden, which developed the recombinase technology.

The TU Dresden Spin-off Seamless Therapeutics Launches with $12.5M Seed Financing to Advance Transformative Gene Editing Platform Based on Programmable Precision Designer Recombinases in Dresden

Seed round co-led by Wellington Partners and Forbion, with additional non-dilutive financial support from the BMBF (GO-Bio funding) enables maturation of the proprietary platform and pipeline towards first clinical evaluation

Seamless Therapeutics, a Dresden based start-up of the Technische Universität Dresden, today announced a $12.5 million (€11.8M) seed financing round which will accelerate further development of its designer recombinases, a novel gene editing platform to transform the treatment of severe diseases. Seamless Therapeutics was founded based on the visionary discoveries from its scientific founders, Prof. Dr. Frank Buchholz, Dean of Research at the Faculty of Medicine and Head of Medical Systems Biology at the University Cancer Center of the Technische Universität Dresden, and his former PhD student Felix Lansing, PhD, Co-Founder and Chief Scientific Officer of Seamless Therapeutics. Both are pioneers in the field of reprogrammable recombinases. Felix Lansing, PhD, will now be responsible for the further development of the company’s proprietary technology.

The company’s pioneering recombinase platform is able to program a widely used and established molecular biology tool to unlock the full potential of gene editing enabling the targeting of any site within the genome. The seed round was co-led by Wellington Partners and Forbion and includes non-dilutive financing from the German Federal Ministry of Education and Research (BMBF GO-Bio,-8B funding), a prestigious German government initiative supporting the most innovative startups in life sciences in Germany. Representatives from both Wellington and Forbion will join the company’s newly formed board of directors. The proceeds from the round will be used to further advance the company’s proprietary technology platform to build a pipeline of therapeutic candidates towards first-in-human readiness as well as to expand the company’s presence in the EU & US.

"I am very happy that our innovative and promising technology can now be transferred from basic research to a potential broad therapeutic application. The financial support provided by the BMBF and the investors will make a major contribution in this regard to advancing the development of this genome editing tool swiftly and purposefully," said Prof. Dr. Frank Buchholz.

“Our modular platform has succeeded in reprogramming site-specific recombinases to any given target sequence effectively breaking the existing hurdles of leveraging this potential best-in-class gene editing system to treat human disease,” commented Felix Lansing, Co-Founder and Chief Scientific Officer of Seamless Therapeutics. “I look forward to working with our founding investors and our highly skilled team to apply our deep knowledge of recombinases to develop a pipeline of novel treatments.”

“Our goal is to apply our deep understanding of recombinases to leverage their inherent benefits to repair genetic alterations that cause disease. We believe our pioneering technology will allow us to shatter the boundaries that exist in gene editing methods today,” said Anne-K. Heninger, PhD, Co-Founder and Chief Executive Officer of Seamless Therapeutics. “Both Wellington and Forbion are visionaries and highly experienced biotech investors, and we look forward to working closely with them in our efforts to transform the gene editing landscape.”

“We have entered a new era in drug discovery based on the promise of how precision gene editing can change the way we treat disease in the future. Seamless Therapeutics has a first-mover position with its innovative platform capable of modifying the long held standard recombination technology into a universal gene editing tool with unprecedented specificity. We are excited to support Seamless Therapeutics in its pursuit of taking a leadership position in the rapidly evolving gene editing arena,” added Karl Nägler, PhD, Managing Partner at Wellington Partners.

“At Forbion our philosophy is to seek out pioneering technologies early in their development and to enable founding teams to harness the true potential of their innovation. The team has developed a powerful new platform that has overcome key limitations of existing gene editing tools, such as CRISPR, prime & base editors,” said Dmitrij Hristodorov, PhD, Partner at Forbion.

Seamless Therapeutics' platform has succeeded in reprogramming site specific recombinases to any given target sequence and make a range of specific changes including inversion, excision, exchange, and insertion from small to larger DNA fragments. Recombinases are a class of enzymes that have been widely used in scientific research for decades to precisely modify the genome of model organisms but until now could not be applied as a therapeutic due to their limited programmability to act on new target sites.

Business Plan Competition - RecTech team from Dresden wins second place at Science4Life Venture Cup

The Dresden research team has developed a promising business concept to revolutionize molecular medicine based on a customized designer recombinase technology. This genome editing technology is predestined to drive the development of new therapeutic approaches for genetic diseases. Today, more than 8,000 gene mutations are known to cause incurable monogenic diseases. By using the designer recombinases developed in Dresden, these genetic defects could be corrected.  Hence previously incurable diseases could be successfully treated. In addition, making use of the genome editing technique offers completely new cures for other diseases, such as viral infections. In order to bring genome editing approaches into clinical practice, it is of utmost importance that the tools used are safe and do not alter the genome accidentally. Designer recombinases have the unique ability to cleave and specifically reassemble DNA in vivo without relying on cellular DNA repair mechanisms. A major advantage over other technologies continues to be that recombinases can correct large structural genome alterations, which has not been possible before. Thus, designer recombinases offer precise and predictable modification of the genome, making them particularly suitable for therapeutic applications. Establishing the necessary platform technology and marketing it profitably defines the innovative business idea of the RecTech project.

In the Science4Life Venture Cup, 88 teams from all over Germany took part to present their innovative business concepts. The ten best contributions were awarded prizes in the first round of the competition and the BMBF-GO-Bio-funded start-up RecTech from Dresden was among the winners. The Dresden team was now also successful in the subsequent rounds of the competition and was able to convince the jurors of its innovative business plan. RecTech took second place in the most competitive phase of the competition, the so-called Business Plan Phase. This is endowed with prize money of € 10,000. The team also scored with the best pitch in the Pharma & Diagnostics category at TechSLAM 2021.

The tailored genome - How enzymes can help to cure hereditary diseases

The start-up project RecTech led by Prof. Frank Buchholz and Dr. Anne-Kristin Heninger has once again succeeded in scoring points in the prestigious Science4Life Venture Cup. This time, RecTech was awarded as one of the ten best teams for its innovative business concept. The participation is highly competitive and offers applicants access to more than 300 industry experts.

The research team of the TU Dresden has developed a promising business concept to establish a flourishing Biotech company in Dresden based on designer recombinase technology. The technology of genome editing applies molecular biological tools to specifically modify the genetic code of organisms. Based on genome editing tools, genetic diseases might be cured in the future by means of "molecular repair". The business idea of the RecTech project is to develop a recombinase platform technology.

Currently, more than 8,000 gene mutations are known to cause genetic diseases that are currently incurable. However, RecTech's designer recombinases enable the development of new curative therapies for such diseases. Sequence-specific recombinases (SSRs) are enzymes that can precisely edit and modify the genome at a specific target sequence. The RecTech team has developed innovative methods to adapt SSRs to any recognition sequence.

In the phase of the Science4Life business plan competition, 81 teams from all over Germany once again participated. This time, the ten best business concepts were awarded within the Venture Cup and the BMBF-GO-Bio-funded start-up RecTech from Dresden was again among them.
