Company News: After U.S. court ruling, Merus reaffirms freedom to operate for its MeMo® transgenic mouse for therapeutic human antibodies
– Regeneron’s ‘018 patent’ is considered invalid and Merus not infringing –
Merus B.V., a leader in developing best-in-class antibody therapeutics to treat cancer patients, today announced a series of pivotal events in its litigation with Regeneron Pharmaceuticals Inc. Previously, Regeneron sued Merus accusing it of infringing U.S. Patent No. 8,502,018 (‘018 patent’) directed to a particular method of making a genetically modified mouse, which Regeneron asserted was useful to produce therapeutic antibodies.
Merus argued that Regeneron had interpreted its patent in an overbroad manner, and that the patent claims were indefinite and invalid. On November 21, 2014, in a fifty-nine page decision, the United States District Court for the Southern District of New York agreed with Merus on virtually every issue, stating: “[t]his Court generally agrees with the constructions Merus proposes, limiting the Patent to a far narrower scope than asserted by Regeneron.” The court also ruled that Merus has demonstrated “clear and convincing evidence that [a key claim term] lacks reasonable certainty and is therefore indefinite.” On December 19, 2014, Regeneron filed papers with the court conceding that under these rulings, Merus does not infringe any asserted claim of the ‘018 patent, and that these claims are invalid. With this ruling and Regeneron’ s concessions, there are no outstanding claims against Merus. The only remaining issues include Merus’ claim against Regeneron that it unlawfully procured its patent from the U.S. Patent Office and Merus’ request that Regeneron pay the legal fees incurred by Merus.
Company News: Anergis Granted U.S. Patent for Ragweed Allergy Vaccine AllerR
– Anergis receives notice of allowance from U.S. Patent Office for patent on ultra-fast treatment for ragweed allergies
Anergis, a company developing proprietary ultra-fast allergy vaccines, today announced that it received a notice of allowance from the U.S. patent authorities for its patent covering composition and methods of use of its ragweed allergy product AllerR. AllerR is based on Anergis´ unique Contiguous Overlapping Peptide (COP) platform. COPs are pharmaceutical-grade, long-peptide immunotherapeutics designed for an ultra-fast, safe and long-lasting treatment of allergy patients.
Ragweed pollen is believed to be the most allergenic of all pollens. Allergies to ragweed pollen are mostly prevalent in the USA, where they affect an estimated 27 million patients, with a high degree of severity in many of them. Among others, ragweed allergies are a major cause of asthma. Fifty percent (50%) of allergic patients in the United States are sensitized to ragweed.
Company News: Anergis Starts Phase II Dose Ranging Trial with Birch Pollen Allergy Vaccine AllerT
– Dose assessment for upcoming Phase III trial
Anergis, a company developing proprietary ultra-fast allergy vaccines, today announced the start of a Phase II trial designed to finalize the dose selection for the Phase III study of AllerT. AllerT is Anergis´ lead vaccine against birch pollen allergy that originated from the company´s proprietary Contiguous Overlapping Peptide (COP) platform. COPs are pharmaceutical-grade, long-peptide immunotherapeutics designed for an ultra-fast, safe and long-lasting treatment of allergy patients.
The randomized, double-blind, placebo-controlled, 4-parallel-group trial will assess the dose response efficacy of AllerT across doses of 50 µg, 25 µg, 10 µg compared to a placebo in an environmental exposure chamber (EEC). Approximately 180 birch pollen allergy patients will receive 5 subcutaneous injections over 2 months. All enrolled patients will be challenged with birch pollen prior to receiving AllerT or the placebo, and 4 weeks after the last injection.
The primary endpoint is the change in Total Rhinoconjunctivitis Symptom Scores (TRSS) from the baseline EEC challenge to the post-treatment EEC challenge.
Secondary endpoints are the mean Total Nasal Symptom Scores (TNSS), Total Ocular Symptom Score (TOSS), Individual Nasal Symptom Scores (NSS) and Asthma Symptom Score (ASS), which will also be evaluated from the baseline EEC challenge to the post-treatment EEC challenge. The trial is being conducted in Canada, with results expected in the third quarter of 2015.
