PETTRA (PLK1 and EGFR Targeted Therapy and Radiation sensitizer): C-siPLK1-NP™
C-siPLK1-NP™ to augment radiotherapy (RT)
Nanoparticle (PDX-NPTM) loaded with cetuximab (EGFR-targeting antibody) and siRNA against PLK1.
C-siPLK1-NP targets EGFR+ cancer cells and reduces PLK1 expression, resulting in reduced DNA repair capacity and G2/M arrest to sensitize cancer to radiotherapy.
C-siPLK1-NP enhances RT sensitivity in vivo.
The combination of C-siPLK1-NP and radiotherapy (RT) significantly reduced tumor growth compared with RT or C-siPLK1-NP alone in NSCLC tumor-bearing mice.
