MENLO PARK, Calif., May 18, 2015 (GLOBE NEWSWIRE via COMTEX) --
Corium International, Inc. CORI, +7.04% a commercial-stage biopharmaceutical company focused on the development, manufacture and commercialization of specialty transdermal products, today announced the publication of promising data on the use of its needle-free transdermal system to deliver influenza vaccine in the June 9, 2015 issue of Vaccine, a pre-eminent publication on vaccines and vaccination. The manuscript, entitled "Fabrication of cell culture-derived influenza vaccine dissolvable microstructures and evaluation of immunogenicity in guinea pigs," details results of a preclinical study conducted by Novartis Vaccines and Corium. Importantly, the results demonstrate the compatibility of Corium's MicroCor® needle-free transdermal system with cell culture-derived influenza vaccines, and establish its potential as a next-generation vaccine delivery system.
In the study, trivalent seasonal influenza cell culture-derived antigens were successfully fabricated for in vivo administration using the MicroCor system and resulted in immunization results comparable to the control vaccine delivered by intramuscular injection. In addition, preliminary data related to the incorporation of influenza antigens within the polymer matrix indicate stability of the antigens in the dried state, suggesting potential for longer-term stability at room temperature. Authors of the paper conclude that "taken together, utilization of cell culture-based production of influenza vaccines along with microstructure delivery could potentially change the way vaccines are administered, particularly in the event of a pandemic."
"There is a significant unmet need for improving influenza vaccine accessibility by providing easy to use and needle-free delivery systems," said Parminder "Bobby" Singh, Ph.D., Chief Technology Officer and Vice President, R&D at Corium and a co-author of the paper. "We believe that use of our MicroCor technology to deliver influenza vaccine could provide significant benefit through improved immunization outcomes and more convenient vaccine delivery based on the results of this study."
About the MicroCor® Transdermal Delivery System
Corium's MicroCor system is a clinical-stage technology utilizing biodegradable microstructures for safe, effective and convenient transdermal delivery of small molecules and biologics, including vaccines, peptides and proteins. The system integrates active agents directly into arrays of solid-state biodegradable microstructures, or "microneedles," that penetrate the outer layers of the skin to release peptides, proteins or vaccines for local or systemic absorption. The solid-state nature of the MicroCor system enables room-temperature stability, simplifying handling, storage and reducing wastage. In addition, there are no needles or sharps left behind after use, providing a safer delivery system for healthcare workers and caregivers. Corium has established GMP manufacturing facilities and quality systems for scale-up, and has developed cost-effective manufacturing processes.
Corium International, Inc. is a commercial-stage biopharmaceutical company focused on the development, manufacture and commercialization of specialty pharmaceutical products that leverage the company's advanced transdermal and transmucosal delivery systems. Corium has developed and is the sole commercial manufacturer of six prescription drug and consumer products with partners Teva Pharmaceuticals, Par Pharmaceutical and Procter & Gamble. The company has two proprietary transdermal platforms: Corplex™ for small molecules and MicroCor®, a biodegradable microstructure technology for small molecules and biologics, including vaccines, peptides and proteins. The company's late-stage pipeline includes a contraceptive patch co-developed with Agile Therapeutics that is currently in Phase 3 trials, and additional transdermal products that are being co-developed with Teva. Corium has multiple proprietary programs in preclinical and clinical development for the treatment of osteoporosis and neurological disorders.
