Climb Bio Gets FDA Fast-Track Designation for Budoprutug in Rare Kidney Disease

By Colin Kellaher


Climb Bio has won the Food and Drug Administration's fast-track designation for its proposed budoprutug treatment for the rare kidney disease primary membranous nephropathy, or pMN.

The FDA's fast-track program is designed to facilitate the development and expedite the review of treatments for serious or potentially life-threatening illnesses with high unmet medical needs.

Climb Bio on Tuesday said there are currently no FDA-approved treatments for pMN, which affects about 75,000 people in the U.S. and can lead to chronic or end-stage kidney disease, requiring dialysis or transplantation.

The Wellesley Hills, Mass., clinical-stage biotechnology company, which is conducting a Phase 2 study of budoprutug in pMN, said it expects to share initial data from the study in the second half of 2026.
