Sanofi Licenses Immune Design's GLAAS Platform to Explore Novel Approach to Treat Food Allergy

CAMBRIDGE, Mass. and SEATTLE and SOUTH SAN FRANCISCO, Calif., Aug. 7, 2014 (GLOBE NEWSWIRE) -- Sanofi (EURONEXT:SAN) (NYSE:SNY) and Immune Design (Nasdaq:IMDZ), a clinical-stage immunotherapy company, today announced that they have entered into a licensing agreement for use of Immune Design's GLAASTM discovery platform to develop therapeutic agents to treat a selected food allergy.

The incidence of food allergies is increasing worldwide in both developed and undeveloped countries, and especially in children.1 Globally, experts believe 220-250 million people may suffer from food allergies.2,3 In the United States alone, as many as 15 million people have food allergies,4 with allergic reactions resulting in an emergency room visit every three minutes and averaging more than 200,000 emergency room visits per year.5

"This is an exciting time in the area of immunology research, and our relationship with Immune Design is a great example of how Sanofi has changed our approach to R&D," said Kurt Stoeckli, vice president and head of Global Bio Therapeutics Organization, Sanofi. "With this partnership, we are able to tap into breakthrough science that holds great potential to transform how food allergies are treated, and the lives of those people affected. This kind of innovation is central to our new approach."

Under terms of the agreement, Immune Design has granted Sanofi an exclusive license to discover, develop and commercialize products to treat a selected food allergy. The company has received an undisclosed upfront payment and will be eligible to receive development and commercialization milestones totaling US $168 million, as well as tiered royalties on sales of approved products.

"Our fourth agreement for the use of the GLAAS platform further demonstrates the broad applicability of this approach not only in cancer and infectious diseases, but now in allergic diseases as well," said Stephen Brady, chief business officer at Immune Design. "Due to the immune dysfunction leading to allergic diseases, GLAAS' mechanism of action is well suited to correct the imbalance, allowing for the potential of new therapeutics in the targeted indication that currently uses century-old technologies. We are pleased that Sanofi has decided to develop products for this often life-threatening and growing food allergy."

Under an existing collaborative research arrangement, Sanofi and Immune Design have generated a large set of preclinical data demonstrating that certain formulations within GLAAS, when given prophylactically or therapeutically, can shift the immune responses in a way that may result in significant protection and reduction from allergy symptoms.

About Sanofi

Sanofi, an integrated global healthcare leader, discovers, develops and distributes therapeutic solutions focused on patients' needs. Sanofi has core strengths in the field of healthcare with seven growth platforms: diabetes solutions, human vaccines, innovative drugs, and consumer healthcare, emerging markets, animal health and the new Genzyme. Sanofi is listed in Paris (EURONEXT:SAN) and in New York (NYSE:SNY).


Immune Design's GLAAS platform works in vivo and is based on a small synthetic molecule called GLA, which stands for glucopyranosyl lipid adjuvant. GLA selectively binds to the TLR4 receptor and causes potent activation of dendritic cells (DCs) leading to the production of cytokines and chemokines that drive a Th1-type immune response. When GLA is accompanied by an antigen and injected into a patient, the combination is taken up by DCs and leads to the production and expansion of immune cells called CD4 T helper lymphocytes with a Th1 phenotype. These CD4 T cells play a key role in boosting pre-existing CTLs that are specific to the same antigen; and providing help to other immune cells, including B lymphocytes that are the precursor to antibodies, and natural killer cells that are also important in the overall immune response. Immune Design believes that GLAAS product candidates have the potential to target multiple types of cancer, as well as infectious, allergic and autoimmune diseases. GLAAS-based product candidates have now been evaluated in over 1000 subjects in Phase 1 and Phase 2 trials demonstrating an acceptable safety profile and efficacy.
