The safety and immunogenicity of the TNFα-Kinoid (TNF-K) have been evaluated in a phase I-II clinical study conducted in subjects with Crohn's Disease (CD). Preliminary results of clinical efficacy are promising.

The principal aim of the present study is to confirm the clinical efficacy of the TNF-K in subjects with moderate to severe CD. Subjects with secondary resistance or intolerance to anti-TNFα monoclonal antibodies will be enrolled in this trial. In addition, the immune responses and the safety elicited by TNF-K will also be evaluated.

Primary Outcome Measures:
  • Clinical remission, defined as a CDAI score ≤ 150 points at week 8. [ Time Frame: Week 8 ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Clinical responses, defined as a decrease of at least 70 points (CDAI-70) and at least 100 points (CDAI-100) in the CDAI score at week 8 vs baseline [ Time Frame: week 8 ] [ Designated as safety issue: No ]
  • Endoscopic response, defined as a reduction of at least 50% in the Crohn's Disease Endoscopic Index of Severity (CDEIS) score or in the Simple Endoscopic Score for Crohn's Disease (SES-CD) at week 12 vs baseline [ Time Frame: week 12 ] [ Designated as safety issue: No ]
  • Biological response as defined by a decrease or normalization of calprotectin levels in stools [ Time Frame: Week 12 ] [ Designated as safety issue: No ]
  • Safety assessments will be conducted throughout the study and will include physical examinations, vital signs, 12-lead electrocardiograms (ECGs), clinical laboratory evaluations, and the recording of adverse events (AEs). [ Time Frame: Week 28 ] [ Designated as safety issue: Yes ]
  • Immunogenicity: o Anti-TNFα antibodies by Enzyme-Linked Immunosorbent Assay (ELISA) o Anti-TNFα neutralizing antibody activity o Anti-KLH antibodies by ELISA [ Time Frame: week 12 ] [ Designated as safety issue: No ]
