| Abstract: | Background: Advanced Combination Treatment (ACT) refers to the dual use of two advanced therapies—either two biologics, two small molecules, or one biologic and one small molecule. There is a lack of guidance regarding clinical trial design for ACT in patients with inflammatory bowel disease (IBD). Key uncertainties remain regarding aspects such as eligibility criteria, pharmacotherapy regimens, safety considerations, and standardised trial design configurations for both induction and maintenance phases. We aimed to formulate expert recommendations regarding the design of ACT clinical trials in IBD. Methods: A systematic search was performed in June 2023. Modified RAND/University of California, Los Angeles Appropriateness Methodology (RAM) was employed to evaluate 287 statements related to the design of ACT clinical trials in patients with IBD. A multidisciplinary panel of gastroenterologists and precision medicine scientists rated statement appropriateness on a 9-point Likert scale. Statements were subsequently categorised as appropriate, uncertain, or inappropriate based on the median panel rating and the presence of disagreement. The consensus meetings were held on February 6, 2024 and June 4, 2024. Findings: ACT should consist of drugs with distinct mechanisms of action, avoiding combinations targeting the same biological pathway. Appropriate eligibility criteria included prior treatment failure and high risk for disease complications. Safety considerations were prioritised, with short-term use of high-risk regimens acceptable for induction therapy. Trial designs should compare ACT to monotherapy and allow for longitudinal evaluation. Co-primary endpoints of clinical remission and endoscopic response were endorsed, with safety outcomes including adverse events and infections. Precision medicine approaches, guided by biomarker analysis, were considered essential for further defining mechanistic pathways and monitoring treatment response. Interpretation: Implementing standardised design elements for eligibility criteria, pharmacotherapy regimens, safety considerations, and trial design configurations will facilitate the conduct of efficient clinical trials of ACT. |
