Prolynx Raises $70 Million to Advance Ultra-Long-Acting Obesity Drugs

The company hired industry veteran Chris Boulton to steer a linker-based platform with prior oncology proof toward IND-ready obesity candidates using data-leveraging regulatory pathways.

Overview

  • The Series A financing was co-led by 5AM Ventures, OrbiMed and Monograph Capital, with investor representatives joining the board.
  • Prolynx is developing extended-duration incretin and non-incretin peptides intended for once-monthly or once-quarterly dosing.
  • Its half-life extension approach uses proprietary chemical linkers to deliver controlled release, which the company says has previously shown clinical proof-of-concept in oncology.
  • Early plans include a longer-acting semaglutide and additional GLP-1/GIP and amylin programs, with a regulatory strategy that builds on existing data, including use of the FDA’s 505(b)(2) pathway.
  • The company has not disclosed when it expects to begin clinical testing of its experimental medicines.
