Sibylla is an innovative start-up founded in 2017 as a spin-OFF of the INFN (National Institute of Nuclear Physics) and the Trento and Perugia Universities. Its multidisciplinary team of co-founders has developed a pioneering Early Drug Discovery method that applies to the research and design of new drugs, effective against diseases so far incurable. Drug discovery is an extremely complex problem, therefore requiring innovation. Sibylla is a beautiful example of how innovation can be pushed forward by a multidisciplinary and agile team. Sibylla's approach is based on the possibility of simulating the folding pathway from the amino acid sequence as produced by the cells' ribosomes to the native state. Traditional pharmacological methods investigate the target proteins' interaction sites in their native, biologically active state. Novel methods act at the DNA level. Sibylla follows an alternative approach. We identify small molecules that bind to pockets found in the intermediate folding state. These pockets disappear in the native state, and that is why we may try to drug proteins which have been so far considered undruggable. Sibylla technology is called PPI-FIT (Pharmacological Protein Inactivation by Folding Intermediate Targeting). A molecule found through PPI-FIT would impair the folding of the protein, leading it to degradation. The overall effect is a selective reduction of the expression level of the target protein. The medical areas focused on by Sibylla's research include oncology and antibiotic resistance, although the technology can be applied to any therapeutic area. The company is developing a proprietary pipeline of potential drugs. We can also provide co-development or identifying potential drugs for pharmaceutical companies' specific targets. We recently signed a collaboration agreement with an important Pharma company. Besides the promising results already achieved, Sibylla keeps being engaged in developing proprietary computing technology.

iOnctura is a clinical-stage biotech developing selective cancer therapies against targets that play critical roles in multiple tumor survival pathways such as cellular proliferation; escape from immune detection; and drug resistance. iOnctura’s pioneering approach to drug development is expected to offer significant clinical benefits over the traditional approach of targeting a single pathway alone. iOnctura has progressed two therapeutic candidates into mid-stage clinical development: IOA-244, a highly selective allosteric inhibitor of PI3Kδ to treat Treg-driven tumors; and IOA-289, a highly selective, non-competitive autotaxin (ATX) inhibitor to treat cancer associated fibroblast (CAF) driven tumors. iOnctura is backed by specialist institutional investors including M Ventures, Inkef Capital, VI Partners, Schroders Capital, and 3B Future Health Fund.

Genkyotex has become a wholly owned subsidiary of Calliditas and have been delisted from the Euronext stock exchanges. Genkyotex’s lead product candidate, setanaxib, is a first-in-class NOX inhibitor that targets NOX 1 and NOX 4, which are major drivers of fibrogenesis in multiple organs. In Q4 2021, Calliditas plans to initiate a 52-week, randomized, placebo-controlled, double-blind, trial with an adaptive phase 2b/3 design with setanaxib in 318 patients with primary biliary cholangitis (PBC). As previously announced in August 2021, Calliditas received FDA fast track designation for setanaxib in PBC. Calliditas will also initiate a Phase 2 proof-of-concept study in head and neck cancer in 2021, which will investigate the administration of setanaxib in conjunction with immunotherapy targeting cancer associated fibroblasts (CAFs).

Endosense is a medical technology company focused on improving the efficacy, safety and reproducibility of catheter ablation for the treatment of cardiac arrhythmias. The company has conducted numerous clinical studies and has shown that using contact force during ablation can reduce procedure time (1), as well as PV gaps at 3-month invasive follow-up (2). The company’s flagship product is the TactiCath Quartz®, the first force-sensing ablation catheter to give physicians a real-time, objective measure of contact force during the catheter ablation procedure. Prior to force-sensing – which Endosense pioneered in catheter ablation - the physicians had to estimate the force applied during ablation. If too much force was applied, there was a risk of perforating the heart wall, if too little force was applied, there was a risk of recurrence; the patient needing a second treatment.

Sequana Medical NV is a pioneer in treating drug-resistant fluid overload, a serious and frequent clinical complication in patients with liver disease, heart failure and cancer. Fluid overload is a well-recognized problem in these growing diseases, causing severe problems for the large number of patients for whom current medicines are no longer effective. These patients can have up to 15 liters of extra fluid in their bodies, causing major medical issues including increased mortality, repeated hospitalizations, severe pain, difficult breathing and restricted mobility that severely impacts daily life. alfapump® and DSR® are Sequana Medical’s proprietary approaches that work with the body to remove this excess fluid, delivering major clinical and quality of life benefits for patients and reducing costs for healthcare systems. Sequana Medical is listed on Euronext Brussels (Ticker: SEQUA.BR) and headquartered in Ghent, Belgium. For further information, please visit www.sequanamedical.com.
