Thermosome raises €4.6m with first financing round and a research grant from the German government

Thermosome GmbH, an emerging biopharmaceutical company, today announces the closing of its first financing round, raising net proceeds of approximately €1.9 million from funds managed by High-Tech Gründerfonds Management GmbH and Bayern Kapital GmbH, respectively, as well as a group of private investors. This first financing round is substantially enlarged by a recently approved grant from the German Federal Ministry of Education and Research (BMBF) providing additionally €2.7 million over the project duration of 3 years.

Thermosome’s TSL technology is a proprietary drug delivery platform used to create thermosensitive drug-loaded nanocarriers which locally release their encapsulated drug within the blood stream upon the influence of mild heat (40-42°C). Thereby, up to 15 fold higher local drug concentrations can be reached while simultaneously reducing the systemic exposure and side effects of conventional parenteral drug application. Various methods for triggering release through focused application of mild heat are clinically established.

Thermosome’s lead candidate is a formulation of a potent, but highly toxic chemotherapeutic drug that has already achieved the pre-clinical proof-of-concept in several animal studies. In these studies, it consistantly showed dramatically improved efficacy at significantly reduced side effects compared to conventional delivery. The proceeds from the first financing round and the grant will be used to move Thermosome’s lead candidate through GMP manufacturing and pre-clinical development into a first clinical study in patients with certain solid tumors. Thermosome envisions to use its novel platform technology to vastly enlarge the therapeutic index and safety window of drugs and reach improved therapeutic outcomes in patients.

The firm’s technology was invented by Prof. Dr. Hansjoerg Eibl at the Max Planck Institute for Biophysical Chemistry in Goettingen. It was applied, among others, in various in vitro and in vivo studies by a research group at the University Hospital of the Ludwig-Maximilians-Universitaet Munich, one of Germany’s leading research universities. “We are happy to see the basic invention of Prof. Dr. Hansjoerg Eibl being transformed into a commercial, biopharmaceutical development”, comments Dr. Florian Kirschenhofer, StartUp & Portfolio Manager at Max-Planck-Innovation GmbH. “We have followed the science behind Thermosome for several years and are delighted to invest into the commercial translation of this very promising technology” adds Dr. Caroline Fichtner, Investment Director at High-Tech Gründerfonds, Europe’s largest early-stage Venture Capital fund.

Thermosome’s managing director, Dr. Pascal Schweizer, adds: “We are very delighted by the strong support of our investors and the BMBF allowing us to move our technology towards the clinical proof-of-concept in humans.” Monika Steger, Investment Director at Bayern Kapital, adds: “We are happy to see the translation of top-notch academic research into emerging high-tech companies in Bavaria and are confident about the commcerical potential of Thermosome.”

About Thermosome
Thermosome® is an emerging biopharmaceutical company leveraging its proprietary drug delivery technology platform for drug development. Through its TSL technology, drug-loaded nanocarriers – so-called Thermosomes – can be created which release their content upon the influence of mild heat. Administered intraveneously, the drug load is instantly released from Thermosomes at non-harming temperatures of 40-42°C, achieved by various clinically established targeted heating techniques such as microwave or ultrasound. With our Thermosomes, up to 15 fold higher local drug concentrations can be reached while simultaneously reducing the systemic exposure and side effects of these drugs (compared to conventional parenteral drug application). Through this novel technology, Thermosome aims to significantly enlarge the therapeutic and safety window of these drugs and reach improved therapeutic outcomes. Thermosome’s lead candidate, a formulation of a potent, but highly toxic chemotherapeutic drug, is currently in pre-clinical development and shall be moved into clinical development against certain solid tumors in the future.
