Food for Thought: Update on Germany´s Drug Reimbursement Law
Based on the latest developments in the debate about Germany´s new drug reimbursement law (AMNOG), we have updated our analysis, which was originally published in September 2010. Please click here for the updated article.
Company News: SuppreMol closes C round, receives grant
Munich-based biotech company SuppreMol this month announced the closing of a EUR15.5 M C round as well as receiving a EUR1.6 M public research grant.
The money will be used for the GMP production and further clinical studies of its lead candidate SM101, a recombinant, soluble, non-glycosylated version of the Fc gamma receptor IIb. SM101, which has been granted orphan drug designation in the European Union and in the US, has already entered Phase Ib/IIa clinical studies in Primary Immune Thrombocytopenia (ITP), with interim results anticipated for next year. In addition, the company plans to initiate a Phase IIa study in Systemic Lupus Erythematosus (SLE) mid next year.
Moreover, SuppreMol will explore the therapeutic potential of SM101 in Lupus Nephritis, a subcategory of this autoimmune disease affecting primarily the kidneys, and evaluate the compound in animal models for the treatment of Chronic Obstructive Pulmonary Disease (COPD). Last not least, the funds will be used for the preclinical development of an anti-FcgRIIb monoclonal antibody, which, due to the different properties of this molecule compared to SM101, may have beneficial therapeutic potential in certain autoimmune diseases.
The C round was led by MIG AG with BioMedPartners AG as co-lead. The other existing investors Santo Holding GmbH, KfW Mittelstandsbank, Bayern Kapital GmbH and Max-Planck-Gesellschaft also participated in the round which was joined by FCP Biotech Holding GmbH as new investor.

Food for Thought: Key to Stopping Alzheimer’s Disease
In Germany, newpapers are widely reporting about a recent paper by a team of researchers led by Thomas Bayer from Ernst-August University Goettingen, Germany, in which the team reports about an approach able to halt the progress of Alzheimer’s disease in mice.
For a long time, researchers have tried to stop Alzheimer’s disease (AD) by either dissolving the plaques found in the brains of AD patients or by trying to get rid of the so-called Abeta peptide that is believed to aggregate to plaques. However, none of these approaches has been successful so far.
A couple of years ago, researchers from the biotech company Probiodrug AG (Halle, Germany) found that the major culprit for the detrimental aggregation of peptides to plaques is not Abeta as such, but a variation carrying a pyroglutamate residue. This pyroglutamated Abeta peptide (pGlu-Abeta), they found, is generated by a hitherto unknown reaction catalyzed by the brain enzyme glutaminyl cyclase (QC). pGlu-formation leads to stabilization of the peptide and protection against cleavage. Moreover, Probiodrug has been able to demonstrate that pGlu-Abeta peptides show increased neurotoxicity, a prolonged half-life and an increased tendency for aggregation. They also form the seeds of the typical plaques observed in the brain of AD patients.
While Probiodrug is developing small molecule inhibitors of the QC enzyme to halt the disease, Thomas Bayer (who is a member of Probiodrug’s Scientific Advisory Board) and his team generated a monoclonal antibody against pGlu-Abeta. Passive immunization of transgenic mice models of AD with this monoclonal antibody significantly reduced overall Abeta plaque load and levels of pGlu-Abeta, and also normalized behavioral deficit in the mice.
Later this month during the Neuroscience 2010 conference, Probiodrug will demonstrate that increasing pGlu-Abeta potentiates the behavioral deficits observed with transgenic AD mouse models significantly, and will also presented data showing that inhibitors of QC can reduce the level of pyroglutamated beta-amyloid species and alleviate the observed behavioral changes.
While the approach presented by Thomas Bayer will take a few years to reach the clinic, Probiodrug’s first small molecule QC inhibitor already has reached the regulatory phase.
