Iron deficiency anemia (IDA), common in patients with inflammatory bowel disease (IBD) due to blood loss, inflammation and malabsorption, negatively impacts patients’ health-related quality of life (HRQOL). Oral iron is often first-line treatment, but many patients do not tolerate it, or do not adequately respond; many live with chronic anemia and its related negative effects. A Phase 3 double-blind, placebo-controlled trial (NCT01114139) previously found that patients unsuccessfully treated with oral iron, including those with IBD, had very poor baseline HRQOL scores associated with fatigue, and that IV iron treatment resulted in significant, clinically meaningful improvement.
