## TL;DR

PAQ Therapeutics makes medicines that get the cell to destroy the faulty KRAS protein that drives many bowel, pancreatic and lung cancers, rather than simply blocking it.

## Summary

PAQ Therapeutics, Inc., based in Burlington, Massachusetts, develops targeted protein degraders against KRAS. PT0253 is in a phase 1 trial, alone and with chemotherapy, in advanced solid tumours with the KRAS G12D mutation (NCT06797336). PT0511, which the company describes as a pan-KRAS degrader, entered a phase 1 trial in KRAS-mutated or amplified solid tumours, with the first patient dosed by January 2026 (NCT07300150). The company announced a USD 39 million Series B in May 2025 and an extension in January 2026 bringing total Series B financing to USD 77 million. Its first registered cancer trial, NCT06797336, was posted on ClinicalTrials.gov in January 2025.
