The Organization

What's happening at Entrada Therapeutics? Entrada is a clinical-stage biopharmaceutical company aiming to transform the lives of patients by establishing a new class of medicines that engage intracellular targets that have long been considered inaccessible.

Our Endosomal Escape Vehicle (EEV™)-therapeutics are designed to enable the efficient intracellular delivery of a wide range of therapeutics into a variety of organs and tissues, resulting in an improved therapeutic index. Through this proprietary, versatile and modular approach, Entrada is advancing a robust development portfolio of RNA-, antibody- and enzyme-based programs for the potential treatment of neuromuscular, ocular, metabolic and immunological diseases, among others.

Our lead oligonucleotide programs are in development for the potential treatment of people living with Duchenne who are exon 44, 45 and 50 skipping amenable. We have also partnered to develop a clinical-stage program, VX-670, for myotonic dystrophy type 1.

We are a tight-knit team of experts and leaders in both therapeutic development and rare diseases and are excited to grow and attract colleagues who are ready to join a high-energy, dedicated team that likes to get things done and dramatically improve the lives of patients and their families.

  • Set-up, inoculate, and operate meticulously shake flasks, small- and medium-scale mammalian cell culture, yeast and bacterial fermentations.
  • Run deep well plates, shake flask for construct screening and process optimization.
  • Perform primary recovery operations such as homogenization, centrifugation, inclusion body wash, solubilization, depth filtration, and refolding.
  • Run SDS-PAGE gels, western blots, and protein concentration assay.
  • Operate AKTA Avant, Bio-Rad NGC FPLC systems for protein purification (as needed)
