Multiple published studies show that needle-free improves vaccine effectiveness

GOLDEN, Colo.--(BUSINESS WIRE)--PharmaJet^�, a company who has developed and commercialized a needle-free platform to more effectively administer drugs and biologics, today announced that their latest research results will be presented at five upcoming conferences in October:

There is a growing body of evidence that shows how PharmaJet's Needle-free Injection Systems (NFIS) can improve the performance of nucleic-acid based vaccine and therapeutics by often providing better immunogenicity in the patient with strong antibody and T-cell responses. The presentations and panel discussions will highlight published data from several partners focusing on the key benefits of needle-free in three highly relevant areas:

• DNA � Needle-free can deliver superior gene expression over electroporation and superior antibody and T-cell immune responses over needle and syringe (N/S).

• mRNA � Needle-free has shown to be an effective delivery method across multiple mRNA platforms (e.g., lipid nanoparticles, protamines, and self-amplifying nucleic acid) compared to N/S.

• Intradermal � Needle-free delivered vaccines can induce strong immune response comparable to intramuscular and subcutaneous injection with a fraction of the dose.

The presentations may also include data from collaborations including those with:

1. Zydus Lifesciences: Researchers conducted a non-human primate study on their Plasmid DNA-based Covid-19 vaccine and saw higher antibody responses with the Tropis� ID System as compared to N/S as well as better protection from challenge with the virus.¹ Subsequently, Zydus conducted a large trial for their COVID-19 vaccine using Tropis to immunize over 28,000 healthy adult volunteers in over 50 sites. The overall efficacy of the vaccine was 66.6%, while it was 100% effective against severe and moderate COVID-19 cases which puts it on par with commercialized peer-group vaccines tested in the same period.²

2. Gennova: The binding antibody and T cell responses of a COVID-19 self-amplifying mRNA vaccine were evaluated in a guinea pig pre-clinical model using multiple doses, and intramuscular (IM) and intradermal (ID) delivery with the PharmaJet Tropis^� System and N/S. ³ The low dose Tropis group produced significantly increased B and T cell responses compared to a higher dose IM N/S vaccination.

�There are currently 18 partner publications that show equivalent or better immunogenicity when using the PharmaJet NFIS compared with either electroporation or traditional needle and syringe,� said Chris Cappello, President and Chief Executive Officer, PharmaJet, Inc. �We continue to grow our pipeline with over 80 studies currently in progress and there are now a broad variety of pharmaceutical products that can be delivered needle-free including nucleic acid-based, inactivated, subunit, live attenuated and viral vector vaccines.�
