CHOP Researchers Find NTRK Fusions More Common than Expected in Pediatric Tumors

In a large study of pediatric cancer patients, researchers from Children’s Hospital of Philadelphia (CHOP) have analyzed the frequency, fusion partners, and clinical outcome of neurotrophic tyrosine receptor kinase (NTRK) fusions, which are clinical biomarkers that identify patients suitable for treatment with FDA-approved TRK inhibitors. The researchers found that NTRK fusions are more common in pediatric tumors and also involve a wider range of tumors than adult cancers, information that could help prioritize screening for NTRK fusions in pediatric cancer patients who might benefit from treatment with TRK inhibitors.

CHOP and Penn Researchers Identify Nanoparticles that Could Be Used in Therapeutic mRNA Delivery before Birth

Researchers at Children’s Hospital of Philadelphia and the School of Engineering and Applied Science at the University of Pennsylvania have identified ionizable lipid nanoparticles that could be used to deliver mRNA as part of fetal therapy. The proof-of-concept study, published today in Science Advances, engineered and screened a number of lipid nanoparticle formulations for targeting mouse fetal organs and has laid the groundwork for testing potential therapies to treat genetic diseases before birth.
