Rigontec GmbH, a privately held biopharmaceutical company developing RNA-based immunotherapeutics for the treatment of cancer and viral diseases, announces the first closing of its Series A financing round, raising €9.45 million. The round was co-led by Wellington Partners and Boehringer Ingelheim Venture Fund, and included NRW Bank and High-Tech Gründerfonds (HTGF).

Rigontec is developing synthetic ligands of a novel receptor of the innate immune system, Retinoic acid Inducible Gene I (RIG-I), which recognizes viral RNA. RNA motifs that activate RIG-I promote the destruction of diseased cells and the induction of a lasting immune memory thereby treating and preventing recurrence of disease.

Rigontec’s lead compound ImOl100, a proprietary first-in-class product targeting RIG-I, is currently being evaluated for development in several cancer types including melanoma and prostate cancer. ImOl100 is a chemically synthesised mimic of the natural ligand of RIG-I with improved safety and drug like properties. In various preclinical models, ImOl100 has demonstrated substantial tumor regression and systemic anti-tumor activity including long-term protection against tumor rechallenge. Rigontec’s technology also allows the design of pipeline candidates with additional gene silencing and inhibitory activities further broadening the applicability of this ground breaking new class of drugs in the area of oncology and viral infections.

Rigontec was launched in January 2014 as a spin-out of the Institute for Clinical Chemistry and Clinical Pharmacology at the University of Bonn, Germany. The Company’s co-founders, Prof. Gunther Hartmann and Prof. Veit Hornung, are internationally highly renowned scientific leaders in the area of innate immune recognition of viral nucleic acids (RNA sensing) and discovered 3pRNA as the ligand for RIG-I. The Company has access to the excellent infrastructure of the University Hospital Bonn, which includes state-of-the art pre-clinical research facilities and a clinical trial unit.

The founding management team is led by Annegret de Baey-Diepolder, an experienced investor and start-up manager, and Christine Schuberth-Wagner, who is in charge of the scientific developments at Rigontec. Prof. Hartmann and Prof. Hornung will stay closely involved with the company as advisors, and Prof. Hartmann will represent the founders on the Board of Directors. On the closing of this funding round, Regina Hodits from Wellington Partners and Marcus Kostka from Boehringer Ingelheim Venture Fund will join the Rigontec Board of Directors.

Gunther Hartmann, co-founder, said: “We are very excited to see that the RIG-I technology which was developed and has matured in our lab over the last eight years is now being taken on into clinical development. Our RIG-I ligands are an innovative class of compounds which directly target the molecular heart of tumor cells. RIG-I activation drives the tumor microenvironment to become an immunogenic tissue – essentially turning tumor tissue into a therapeutic tumor vaccine. This is a potent therapeutic principle by itself and it has the potential to synergistically complement the molecular principle of immune checkpoint inhibitors.”

Annegret de Baey-Diepolder, co-founder and interim CEO of Rigontec, said: “I am delighted that Rigontec has secured significant funding from experienced life sciences investors to support the development of this exciting new business. We believe that our proprietary technology, based on world-class research, has the potential to create a new generation of immunotherapies for the treatment of cancer and viral diseases.”

Regina Hodits, General Partner at Wellington Partners, commented: “Rigontec has a truly different approach to cancer immunotherapy based on ground-breaking science in the up-and-coming field of RNA sensing. This forms a solid basis for developing medicines which may allow for both near-term efficacy and also potentially long-term protection. These could make a significant difference to cancer patients and patients suffering from chronic viral infections. We are very pleased to be supporting Rigontec in striving to become a leading player in this exciting space.”

Marcus Kostka, Director at Boehringer Ingelheim Venture Fund, added: “The team at Rigontec has made excellent progress in the short time since founding to build a strong foundation for the further development of their lead candidate and a pipeline of products based the Rigontec technology. We look forward to working with the Company as it strives to fulfil the potential of this novel approach for the benefit of patients.”
