A stable and high potency dry powder measles vaccine with a particle size distribution suitable for inhalation was manufactured by CO2-Assisted Nebulization with a Bubble Dryer® (CAN-BD) process from bulk liquid Edmonston-Zagreb live attenuated measles virus vaccine supplied by the Serum Institute of India. A novel dry powder inhaler, the PuffHaler® was adapted for use in evaluating the utility of cotton rats to study the vaccine deposition, vaccine virus replication, and immune response following inhalation of the dry powder measles vaccine. Vaccine deposition in the lungs of cotton rats and subsequent viral replication was detected by measles-specific RT-PCR, and viral replication was confined to the lungs. Inhalation delivery resulted in an immune response comparable to that following injection. The cotton rat model is useful for evaluating new measles vaccine formulations and delivery devices. © 2010 Elsevier Ltd.

The development of unit-dose, inhalable, antibiotic microparticles for use in primary and combined therapy approaches to treating tuberculosis (TB), multi-drug-resistant (MDR-TB), and extensively drug-resistant TB is explored using the gentle drying process of Carbon-dioxide Assisted Nebulization with a Bubble Dryer (CAN-BD). The microparticles produced using this method contain capreomycin, kanamycin, and isoniazid, respectively, imbedded in L-leucine. Antibiotics were developed into inhalable antibiotic formulations for their utility in both first line and second line antibiotic treatment regimens. Capreomycin and kanamycin are typically administered by injection making them desirable candidates for the development of a needle-free delivery system that addresses the Grand Challenges in Global Health Initiative #3. In response to this challenge, unit-dose packaging that preserves powder properties by protecting them from moisture, oxidants, and UV exposure, and a low cost active dry powder inhaler, the PuffHaler, were developed and used as a prototype device, in addition to the Aerolizer, to disperse the microparticle antibiotic formulations. Antibiotic formulations show yields above 50% in small-scale powder production by CAN-BD. Capreomycin and kanamycin show improved powder yields in scale up experiments. The particle properties were characterized using scanning electron microscopy, Karl Fischer moisture analysis, Anderson Cascade Impaction studies, and X-ray diffraction. The inhalable antibiotic formulations are within a respirable size range (1-5 μm), and have less than 3% residual moisture. Unit-dose dry powder antibiotics have the potential to provide easy-to-use, stable products with improved safety profiles. © 2012 Copyright Taylor and Francis Group, LLC.

"Measles is a highly contagious, human disease that is spread by the respiratory route, and, in the developing world, remains a leading cause of death due to vaccine-preventable infectious diseases in children younger than 5 years. The most recent estimates are that there were 139,300 deaths worldwide in 2010 due to measles. Research priorities to help achieve the goals of controlling, and eventually eradicating, measles worldwide should include the development of thermostable alternative delivery methods to improve vaccine safety, effectiveness, and coverage. In this Phase I SBIR project, we aim to develop dry wafer formulations for sublingual administration that are thermally stable (Aim 1) and immunogenic (Aim 2). We will use Aktiv-Dryʼs patented CO2-Assisted Nebulization with a Bubble Dryer® (CAN-BD) technology to prepare dry powders of measles vaccine formulations containing novel excipients to enhance stability. These powders will then be processed into wafers. We anticipate the outcome of the proposed research will be the development of a dry wafer formulation that exhibits less than one log loss in measles vaccine virus titer after 6 months of storage at 37 °C. Furthermore, the sublingual vaccine wafers will clearly induce an immune response in cotton rats, an accepted model for measles research.

DESCRIPTION (provided by applicant): The overarching goal of this project is to move a new, dry powder formulation of Hepatitis-B vaccine on its path to commercialization. In the Phase I SBIR we tested in vitro three Hep-B dry powder formulations of commercially available Shanvac-B and demonstrated powder stability and immunogenicity at temperatures ranging from -20 ?C through 65 oC. At these temperature extremes the currently marketed liquid Hepatis B vaccine is inactivated as the HBsAg antigen separates from the alum adjuvant. Our studies also showed that the dry micro-scale powders dissolved very rapidly, suggesting their utility in single dose auto-reconstitution devices aimed at parenteral administration. These results have far-reaching implications inregard to vaccine storage, transport and administration, especially in developing countries where limited refrigeration and electric power and high ambient temperatures restrict the useful life and potency of liquid vaccines. In the proposed Phase II SBIRstudy, we will choose the optimum formulation from the three that we developed earlier and pair this powder with a single dose auto-reconstitution device being developed by Becton Dickinson (BD). The drug- device combination will be used to assess potency in a mouse model compared to a control group of animals that will be administered Shanvac-B by needle and syringe. Potency will be assessed from ELISA analysis of animal sera. . The outcome of the Phase II work will be judged based on the potency of the Hep-B dry powder formulation and the functionality and performance of the BD device as compared with the potency of the needle and syringe administration. PUBLIC HEALTH RELEVANCE: This project seeks to accelerate a new Hepatitis-B vaccineformulation on its path to commercialization. A commercially available thimerosal-free liquid vaccine, Shanvac-B, was formulated as a dry, rapidly dissolving micro-powder with stability over an 18-month period at temperatures ranging from -20 oC through 65oC. When considered in the context of combining Aktiv-Dry's vaccine powders with single dose auto-reconstitution devices, these results have far-reaching implications in regard to vaccine storage, transport and administration, especially in developing countries where limited refrigeration and electric power and high ambient temperatures restrict the useful life and potency of liquid vaccines.
