- PharmaJet needle-free technology can improve DNA vaccine delivery1 and has been successfully adopted into multiple cancer vaccine development programs.
- Partner study data shows how PharmaJet technology can outperform needle and syringe while providing safety, efficacy, and improved patient comfort.
- PharmaJet continues to execute on its strategy to be the best-in-class delivery system for novel DNA and RNA cancer immunotherapies.

- Evaxion: In Phase 1/2 trials the Stratis Needle-free Delivery System was used to administer EVX-02 DNA vaccine in combination with CPI (nivolumab) to patients that had a complete resection of Stage IIIB/IIIC/IIID or Stage IV melanoma and were a high risk of recurrence. The study, comparing Stratis delivery to poloxamer delivery with needle/syringe showed EVX-02 was immunogenic with an improvement in T cell induction when using Stratis compared to needle/syringe. These patients were relapse-free at their last assessment.2 The 2nd generation EVX-03 vaccine induced a more potent response in a pre-clinical model.
- Scancell: The Phase 2 trial with patients that have advanced unresectable melanoma who have received the SCIB1 or ISCIB1+ DNA vaccine with CPI, either with nivolumab and ipilimumab or pembrolizumab is ongoing. Latest data shows SCIB1 administered with Stratis has induced T cell responses in 87% of patients who have been given double CPI and showed a significant increase from baseline T cell counts with full cohort data still to be analyzed.3 According to Lindy Durrant, Scancell CEO, “To date, Stratis is the only technology which has shown effective uptake of the DNA vaccine through intramuscular delivery allowing native cellular machinery to express the target antigen and induce a potent anti-tumor response.”4
