Pre-Clinical models demonstrate potential benefits of lymphatic targeting with Sofusa proprietary nano-draped microneedles1

  • >40-fold increase in drug concentration in lymph nodes vs subcutaneous injections (SC) or intravenous (IV) infusions
  • Improved tumor penetration with 1/10th dose
  • Improved anti-tumor efficacy and reduced metastases

Human Clinical Phase 1B RA study to assess intra-lymphatic delivery2

  • 12-week open label study enrolling patients with inadequate response to 50mg weekly Enbrel® subcutaneous injections (n=10)
  • First 3 patients completed, 25mg weekly doses (50% of SC dose)
  • 36%/38% reduction in Disease Activity (DAS28 ESR/CRP)
  • 80% reduction in swollen joints count
  • 77% improvement in Physician Global Assessment Score
