A combination of both pirfenidone plus nintedanib is not allowed. Where approved, patients not currently receiving treatment with pirfenidone or nintedanib therapy should have a valid reason: this includes contraindication to therapy (including concerns around DDI), previous treatment discontinued due to lack of response or tolerability, not meeting national or regional eligibility criteria for anti-fibrotic treatment, or patient choice.
