Innovative Dose Escalation Strategy for Infliximab Therapy

Innovative Dose Escalation Strategy for Infliximab Therapy

Celltrion, a prominent biopharmaceutical company based in Incheon, South Korea, recently unveiled exciting findings regarding the two-year efficacy of dose escalation therapy with subcutaneous infliximab, known as CT-P13 SC. These results were announced at the United European Gastroenterology (UEG) Week 2024.

The study focused on patients with inflammatory bowel diseases (IBD) including Crohn's disease and ulcerative colitis. The analysis emerged from the LIBERTY studies, demonstrating that individuals who showed initial positive responses to intravenous induction therapy but later experienced a loss of response benefited significantly from the CT-P13 SC dose escalation procedure.

Study Findings and Clinical Success

According to the results discussed at the conference, there was a noteworthy improvement in clinical remission rates among patients after 102 weeks of therapy. Specifically, around 70.3% of Crohn’s disease patients and 35.2% of ulcerative colitis patients experienced clinical remission by the end of this period. Furthermore, 40.5% of Crohn's patients showed a positive endoscopic response after undergoing dose escalation.

Patients who opted for dose escalation during the study experienced significant reductions in their modified Mayo score in ulcerative colitis and CDAI score in Crohn’s disease. The analyzed data underscores the efficacy of this approach, with statistical analyses supporting the advantages of adjusting doses over a prolonged treatment period.

Safety Profile and Long-term Management

One of the most reassuring outcomes of the study was the consistent safety profile observed with the CT-P13 SC dose escalation. Throughout the two years of monitoring, no new safety concerns emerged, illustrating that patients managed under this therapy could enjoy continued support without significant risks.

"Dose escalation has been a renowned option for tailoring treatment strategies for IBD patients, especially those losing their initial responses. Our post-hoc analysis shows that this method can significantly enhance efficacy and optimize outcomes for patients who have previously responded to therapy," explained Professor Stefan Schreiber from the University Hospital Schleswig-Holstein in Germany during a presentation of the findings.

Enhancing IBD Management Strategies

Celltrion's Executive Vice President, Mr. Kevin Byoung Seo Choi, expressed pride in sharing these pivotal findings, noting their commitment to improving treatment avenues for IBD patients. The study not only supports current understanding but also adds a valuable layer to clinical practice. Healthcare professionals are now equipped with the ability to craft personalized treatment plans for their patients based on unique responses to therapy.

Furthermore, the updated Summary of Product Characteristics (SmPC) clearly indicates that doses can be adjusted for patients who initially responded to a 5mg/kg dosage but later experienced a drop in efficacy. This adaptability is crucial in the ongoing journey of managing IBD, a condition known for its complexity.

About CT-P13 and Its Approval

CT-P13 SC is recognized as the world’s first subcutaneous formulation of infliximab, representing a significant advancement in IBD therapies. Approved for use in over 60 countries, including major markets such as the United States and European Union, the SC formulation provides consistent drug exposure while offering a convenient method of administration that enhances patient adherence and satisfaction.

Subcutaneous infliximab demonstrated potential advantages over traditional intravenous methods due to its streamlined administration process. This innovation makes it an appealing option for many patients dealing with the challenges of administering ongoing IBD treatments.
