abstract = {Inflammatory bowel disease (IBD), consisting of Crohn's disease (CD) and ulcerative colitis (UC), is a chronic inflammatory condition of the gastrointestinal tract with significant clinical impact, leading to debilitating symptoms, impaired quality of life, and an increased risk of complications such as colorectal cancer. This review provides a comprehensive overview of current and emerging therapeutic strategies for IBD. We conducted a narrative review to explore therapeutic advances in IBD treatment, focusing on mechanisms of action, clinical development, and current therapeutic challenges. We analyzed existing knowledge on clinical drug development for IBD, up to July 2025. Our search encompassed databases including PubMed, ClinicalTrials.gov, and Google Scholar, using keywords such as "Inflammatory bowel disease", "Crohn's disease", "Ulcerative colitis", "therapeutics", and relevant drug names. We delve into key progress in approved drugs in recent years, including biologic and targeted small molecule therapies, which have advanced the treatment paradigms by offering more precise targeting of inflammatory pathways. This review also covers investigational drugs in clinical development, including biologics and small molecules against novel molecular targets, cell and gene therapies, precision medicine approaches, and microbiome-based interventions. Those novel therapies could potentially address unmet medical needs by achieving deeper and more durable responses, inducing remission, preventing disease progression, and ultimately improving long-term patient outcomes. This review summarizes the latest progress in IBD treatment, outlines the advantages, pitfalls, and research prospects of various drugs and therapies, aiming to provide a foundational understanding for both clinical decision-making and future IBD research.},
