Company News: SuppreMol Obtains Option to In-License Antibody Against Interleukin 3 for Rheumatoid Arthritis

SuppreMol GmbH, a privately held biopharmaceutical company developing innovative therapeutics for the treatment of autoimmune diseases, today announced that it has closed an agreement to in-license an antibody directed against interleukin 3 (IL-3), which has been developed by the Molecular Immunology research group led by Prof. Dr. Matthias Mack at the University of Regensburg.

IL-3, a growth factor primarily produced by activated T cells, stimulates growth and differentiation of monocytes, basophils and other leukocyte populations from the bone marrow in an immune response. Recently, the team of Prof. Mack was able to demonstrate that IL-3 plays an important role in the onset of Rheumatoid Arthritis, an autoimmune disease characterized by a chronic inflammation of the joints and other organs affecting up to one percent of the population in the industrialized world. The disease commonly leads to significant disability and reduction in the quality of life and is connected with significant costs for patients and the health care systems.

Therapy with an antibody-based IL-3 inhibitor, either in early stages or during flares and exacerbations, may provide a new class of treatment for patients suffering from Rheumatoid Arthritis.

Company News: Curetis AG Successfully Increases Series A Round to EUR 24.5 Million

Curetis AG, an innovative molecular diagnostics company focusing on the development and commercialization of in-vitro diagnostic products for infectious diseases, today announced an extension of its Series A financing, bringing the total size of the round to € 24.5 million. CD-Venture joined the funding as a new investor, while all of Curetis’ existing VC investors participated in the round. Several private investors also continued to co-invest.

Following the appointment of Oliver Schacht, PhD, as the new CEO of Curetis last month, this financing transaction is the first step towards funding next year’s commercial launch and roll-out of the Unyvero product platform together with the first CE marked IVD test cartridge for pneumonia and antibiotic resistances in Europe. The additional funds will allow Curetis to pursue a more aggressive strategy towards initiating a US clinical trial in H2-2011 with a goal of filing for FDA approval in 2012. This Series A financing positions Curetis as a solidly funded molecular diagnostics company with near-term commercial-stage products and its unique platform solution addressing a clear unmet medical need in the rapid diagnosis of infectious diseases and antibiotic resistance.

Curetis’ CEO Oliver Schacht will present an update on the company at the upcoming BioEquity 2011 in Paris. The presentation is scheduled for May 23, 2011, at 5:00 pm CET, Room Pont de Sully.

Food for Thought: Weekly Wrap-Up

Sascha Karberg in Frankfurter Allgemeine Sonntagszeitung (FAS) features the latests attempts of biologists to understand and replicate the endosymbiosis of cyanobacteria and cells of eucaryotes that led to the chloroplasts found in all green plants. Already in the 1970s, biologists successfully incorporated cyanobacteria into an amoeba and meanwhile, several animals carrying endosymbionts providing them with extra energy from the sun have been discovered. This is now replicated in the lab. Using genetically engineered cyanobacteria, scientist recently created zebrafish larvae as well as mice and hamster cells with endosymbionts that not only survive but replicate. Karberg also explains why this will not lead to green cows living on sunlight.

Silvia von der Weiden in Die Welt introduces novel findings about the role of water molecules in protecting and maintaining the DNA geometry. Reducing or expanding the size of the water sheath covering the DNA changes the conformation of the molecule as if activating a switch. The findings may be used to create novel DNA-based nanotools or develop DNA-binding drugs to influence gene activation.

In Forbes, Mattew Herper features a graph proving Moore’s law wrong – at least in the decline of cost of DNA sequencing: the cost of getting DNA data (i.e. cost per genome as well as per megabyte of DNA sequence) is dropping way faster than the cost of processing data on computers. In a separate article, Herper endorses Wall Street’s forecast, that Pfizer’s Prevnar 13 vaccine against pneumococcus infections will be the company’s biggest seller in five years.

The Economist features an Italian engineering firm developing a system to collect oil spills in the sea that is based on wool. Already the company has been granted a patent of its containerized, ship-based kit. After absorbing the oil, the wool is pressed to recover the oil and the reused.

Andrew Pollack in the New York Times reports about setbacks in the development of treatments based on stem cells. Experiments recently  showed that induced pluripotent stem cells – which are thought to be superior both ethically and technically to embryonic stem cells – are rejected by the immune system. However, it is not yet clear whether the results obtained in mice hold true for humans, too.

 

Company News: biocrea and Pfizer Jointly Presented Details on Novel PDE10 Inhibitors at the 241st ACS National Meeting & Exposition

– Novel treatment opportunities for CNS diseases –

biocrea, a biopharmaceutical company focusing on novel treatments for disorders of the central nervous system (CNS), today reported details on the design and synthesis of novel, brain-penetrating phosphodiesterase-10 (PDE10) inhibitors developed in collaboration with Pfizer Inc. (NYSE: PFE). The data were featured in joint presentations[1] with Pfizer at the recent 241st ACS National Meeting & Exposition, an event organized by the American Chemical Society (ACS).

The data demonstrated that the scientists at Pfizer and biocrea were able to eliminate undesired activity on adenosine receptors and to considerably improve the compounds´ physicochemical properties and potency. The team had started with initial high-throughput hits characterized by low potency and selectivity. Further lead optimization led to a number of compounds with very robust activity in a range of preclinical models of anti-psychotic efficacy. Moreover, these PDE10 inhibitors produced low levels of catalepsy, suggesting a minimal risk for the induction of side-effects involving the extrapyramidal system (EPS), the most common adverse reaction observed with anti-psychotic drugs.

Phosphodiesterases (PDEs) have been identified as key regulators of intracellular cyclic nucleotide levels in the brain. Mechanistically, PDE10 inhibition has two major benefits, mimicking, (1) the effects of antagonists of the dopamine-2 receptor, the current standard treatment for psychosis, and (2) the effects of agonists of dopamine-1 receptors, which may decrease the side-effect liabilities while contributing to a pro-cognitive profile.
