Company News: Anergis Presents Preclinical Data of its Ragweed Allergy Vaccine Candidate AllerR
– AllerR induces formation of antibodies recognizing natural ragweed allergens –
Anergis, a company developing breakthrough allergy vaccines for fast and safe allergen-specific immunotherapy, reported today that it will present preclinical data for its ragweed allergy vaccine at the 2013 Annual Meeting of the American Academy of Allergy, Asthma & Immunology (AAAAI) in San Antonio, TX.*
The results demonstrate the hypoallergenicity of AllerR and the successful recognition of the natural ragweed allergen Amb a 1 by the mouse immune system after immunization with AllerR.
The poster no. 136 will be presented on Saturday, February 23, 2013, at 9:45am CST in session no. 2210 “Immunotherapy I” at the Henry B. Gonzalez Convention Center, Street Level, Exhibit Hall C. The abstract of the poster titled “Non-Detectable IgE Binding of an Amb a 1 Derived, Contiguous Overlapping Peptide Based, SIT Product Candidate Against Ragweed Allergy” is available at:

AllerR is a mix of seven Contiguous Overlapping Peptides (COPs) derived from the COP platform of Anergis. In the experiments, AllerR showed no detectable IgE binding in competition ELISA tests using sera from allergic patients and did not induce degranulation of humanized basophil cells, a standard test used to test the ability of a protein or peptide to elicit an allergic reaction in humans. In addition, mice sensitized to the natural allergen Amb a 1 showed no reactivity to AllerR, whereas the administration of Amb a 1 in these animals lead to anaphylactic responses. The immunogenicity of AllerR was also tested in naïve mice and showed that each COP composing AllerR elicited an antibody response and that these antibodies specifically recognized the natural Amb a 1 allergen.
In the U.S., ragweed pollen allergy is the major cause of hay fever: 75% of all patients suffering from pollen allergies carry a ragweed pollen allergy. It affects about 20% of the U.S. population and is also on the rise in Europe due to the spread of ragweed (Ambrosia genus) plants accidentally introduced to Europe. The major allergenic protein has been identified as Amb a 1, a 38 kDa non-glycosylated protein composed of two subunits.

Company News: Anergis Expands Management Team
– Company Appoints Gilles Della Corte as Director of Clinical Development and Eva Castagnetti as Director of Product Development –
Anergis, a company developing breakthrough allergy vaccines for fast and safe allergen-specific immunotherapy, today announced the expansion of its management team. With the appointments of Gilles Della Corte as Director of Clinical Development and Eva Castagnetti as Director of Product Development, the company has significantly strengthened its late-stage drug development expertise.
Gilles Della Corte, MD, brings to Anergis extensive expertise in global clinical development. In the past 22 years, he worked both for pharmaceutical companies, including Rhone-Poulenc Rorer, Servier, Solvay Pharma, Serono and Merck Serono, and for CROs where he held various senior positions in Research and Development. He has significant experience with all stages and aspects of clinical drug development ranging from Phase I to Phase IV. A cardiologist and pharmacologist by training, Gilles also holds diplomas in statistics and clinical trial methodology.
Eva Castagnetti, PhD, has several years of experience in both technical and business management functions in the biopharmaceutical industry with Lonza, Senn Chemicals and Rapid Pharmaceuticals. She has been responsible for the development and production of Active Pharmaceutical Ingredients (peptides) in early to late clinical phases, gaining comprehensive experience of the regulatory and quality requirements in the development of new pharmaceutical products. Eva obtained her PhD in organic chemistry in 2001 from the University of Lausanne/EPFL and spent two years as a postdoctoral fellow at the Massachusetts Institute of Technology (Cambridge/Boston) and at the ETH Zurich.
Company News: VAXIMM Reports Positive Topline Data from First Oral Cancer Vaccine Trial
– Study meets endpoints and demonstrates safety and tolerability of VXM01 –
VAXIMM AG, a Swiss-German biotech company focusing on oral cancer vaccines, announced today topline data from the first clinical trial of its investigational oral cancer vaccine VXM01. The randomized, placebo-controlled, double-blind Phase I/II dose escalation study met all key endpoints and demonstrated safety and tolerability.
The study code-named VXM01-01-DE enrolled 45 patients with inoperable pancreatic cancer at the Heidelberg University Hospital (Heidelberg, Germany). In addition to standard-of-care treatment, the patients received several doses of VXM01, a therapeutic vaccine targeting the tumor vasculature, or placebo.
The results of the study indicate that the vaccine was safe and well tolerated. No dose-limiting toxicities were observed. Besides this primary endpoint, several important secondary endpoints, including specific T-cell response and changes in tumor perfusion, were met. After vaccination with VXM01, a quarter of the patients showed a strongly increased T-cell mediated immune response against the target (VEGFR-2). This effect was distinct from fluctuations observed in the placebo-treated patients. Immunologically responding patients occurred already in the lowest dose group. A third of the VXM01-treated patients had a strong drop in tumor perfusion following the treatment, accompanied by corresponding changes in tumor-specific and angiogenesis-related biomarkers. Tumor perfusion changes in the treatment group were correlated with the VEGFR-2 specific effector and regulatory T-cell responses. More detailed results from the trial will be submitted for presentation at upcoming scientific meetings and for publication in a peer-reviewed journal.
“We are delighted to see that VXM01 was safe and well tolerated in the patients we treated,” said PD Dr. Hubertus Schmitz-Winnenthal, principal investigator of the study. “We are especially excited about the encouraging data observed in the two key secondary endpoints. The vaccine seems to be able to induce and enhance the VEGFR-2 specific T-cell response and to impact tumor perfusion in a good proportion of treated patients.”
“We are very encouraged by these data,” added Dr. Heinz Lubenau, General Manager of VAXIMM GmbH, a fully owned subsidiary of VAXIMM AG in Germany. “It provides a strong basis for continuing the development of VXM01 for the treatment of solid tumor diseases. Following regulatory approval, we plan to re-open the study VXM01-01-DE for further recruitment of pancreatic cancer patients.”
Dr. Klaus Breiner, Executive Chairman of VAXIMM AG commented: “We are very pleased with this outcome. This first-in-man study was already designed as a placebo-controlled trial, providing us with a high level of confidence in the validity of the results.”
Company News: Merus Achieves Milestone with Novartis Option Fund
– Company Reaches Milestone in Biclonics™ Program Partnered with Novartis –
Merus B.V., a biopharmaceutical company focusing on innovative human antibody therapeutics, today announced it has met the second milestone in its option agreement with the Novartis Option Fund (NOF). The achievement triggers an undisclosed milestone payment.
In 2010, Merus had entered into an option agreement with the Novartis Option Fund for an exclusive license to one of Merus’ oncology programs. The deal grants the Novartis Option Fund rights to a product candidate created by the Biclonics™ and Oligoclonics™ technologies of Merus. Merus is potentially entitled to milestone and license payments in excess of $200 million, as well as royalties.
Ton Logtenberg, CEO and founder of Merus, commented: “Reaching this key milestone in our program partnered with NOF underlines the power of our platform to generate antibodies addressing multiple targets simultaneously with high potency and the desired functional activity.”
