This is a multicenter non-randomized prospective open label trial of partial enteral nutrition (PEN) among patients with active Crohn's disease (CD) starting standard of care advanced therapy. Our central hypothesis is that combination therapy of PEN and pharmacologic therapy is more efficacious than pharmacologic therapy alone and can be well-tolerated for patients. Participants will choose to either include PEN along with starting their advanced therapy or will choose not to include PEN. 80 participants will be recruited from 15 sites across the United States.
