The TNF-α antagonist golimumab is approved for the treatment of ulcerative colitis but not for Crohn's disease (CD). We herein report a case series of 8 difficult-to-treat patients with severe and refractory CD receiving golimumab as an off-label rescue medication and fourth-line anti-TNF agent in our tertiary referral inflammatory bowel disease center.
We performed a retrospective analysis of clinical, biochemical, and radiological as well as endoscopic parameters. The patients all suffered from severe refractory CD with ongoing symptoms. Moreover, all 8 patients had previously been treated with all 3 other TNF-α antagonists approved for CD in Switzerland (infliximab, adalimumab, and certolizumab pegol) without durable clinical response.
Three out of 8 patients showed a primary nonresponse. Among the 5 patients responding after induction, 1 patient showed a loss of response, and in 1 patient, treatment was terminated due to side effects. Three patients have a continuous clinical response under golimumab. We did not observe any severe adverse events during golimumab administration.
A considerable fraction of this highly selected subgroup of difficult-to-treat CD patients responded to golimumab, indicating a promising potential for refractory CD patients, including those with multiple previous anti-TNF exposures.
