Wednesday, February 22, 2023

As part of the partnership agreement, Nanite will design delivery vehicles for genetic medicines to Schwann cells via PNPs, an emerging technology for drug delivery to hard-to-hit targets.

Key Points: 
  • As part of the partnership agreement, Nanite will design delivery vehicles for genetic medicines to Schwann cells via PNPs, an emerging technology for drug delivery to hard-to-hit targets.
  • This makes Schwann cells the primary target of genetic therapies in most cases of CMT.
  • The safe delivery of medicines to the Schwann cells of patients with CMT1A, would mark a dramatic step forward in the potential of gene therapies for CMT disease.
  • The CMT Research Foundation (CMTRF) is focused solely on delivering treatments and cures for CMT.

  • The findings on patients with the 1A subtype of CMT (CMT1A) showed that patient-reported symptoms burden is high, with study participants registering difficulties using limbs, fatigue, pain, and impaired quality of life.
  • Burden severity appears to differ across the population, possibly driven by differences in rehabilitative and prescription-based interventions, and country-specific health care variability.
