Clinical Trial Summary

The purpose of this study is to evaluate the efficacy and safety of JNJ-64304500 as add-on therapy to standard of care (SOC) biologic treatment with anti-tumor necrosis factor alpha or anti-interleukin 12/23 inhibitors in participants with active Crohn's disease in response but not remission to SOC biologic therapy.

Description:

Biologic agents such as anti-tumor necrosis factor (TNF) and interleukin (IL)-12/23 antagonists have become the standard of care (SOC) in the treatment of patients with Crohn's disease. However, many patients fail to fully respond to treatment. This study will evaluate the efficacy of 10 week add on treatment with JNJ-64304500, compared to placebo, in patients taking SOC anti-TNF or anti-IL12/23 biologics. The study consists of a screening phase (up to 8 weeks); treatment phase (up to 12 weeks and follow-up phase (up to 16 weeks after the last administration of study agent). The total study duration will be up to 34 weeks. Key safety assessments include adverse events, clinical laboratory tests (hematology and chemistry), vital signs, monitoring for injection-site and hypersensitivity reactions, and early detection of active tuberculosis.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Participants with Adverse Events (AEs) and Treatment Emergent Adverse Events (TEAEs)	An AE can be any unfavorable and unintended sign (including an abnormal finding), symptom, or disease temporally associated with the use of a medicinal (investigational or non investigational) product, whether or not related to that medicinal (investigational or non investigational) product. TEAEs are AEs with onset during the intervention phase or that are a consequence of a preexisting condition that has worsened since baseline.	Up to Week 26
Primary	Number of Participants with Treatment-emergent Serious Adverse Events (SAEs)	TEAEs are AEs with onset during the intervention phase or that are a consequence of a preexisting condition that has worsened since baseline. A SAE is any untoward medical occurrence that at any dose: results in death; is life-threatening; requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability/incapacity; is a congenital anomaly/birth defect; is a suspected transmission of any infectious agent via a medicinal product; is medically important.	Up to Week 26
Primary	Number of Participants with TEAEs by System Organ Class with a Frequency Threshold of 5 Percent (%) or More	Number of participants with TEAEs by system organ class with a frequency threshold of 5 % or more will be reported.	Up to Week 26
Primary	Number of Participants with Infections, Serious Infections and Infections Requiring Antimicrobial Treatment	Number of participants with infections, serious infections and infections requiring antimicrobial treatment will be reported.	Up to Week 26
Primary	Number of Participants with Clinically Significant Abnormalities in Vital Signs	Number of participants with clinically significant abnormalities in vital signs will be reported.	Up to Week 26
Primary	Number of Participants with Clinically Significant Abnormalities in Laboratory Tests	Number of participants with clinically significant abnormalities in laboratory tests will be reported.	Up to Week 26
Primary	Number of Participants with AEs Leading to Treatment Discontinuation	Number of participants with AEs leading to treatment discontinuation will be reported.	Up to Week 26
Primary	Change from Baseline in the Crohn's Disease Activity Index (CDAI) Score at Week 12	Change from baseline in the CDAI score at Week 12 will be reported. CDAI will be assessed by collecting information on 7 different Crohn's disease-related variables (extra-intestinal manifestations, abdominal mass, weight, hematocrit, total number of liquid or very soft stools, abdominal pain/cramping and general well-being) with scores ranging from 0 to approximately 600. The last 4 variables are scored over 7 days by the participant in a diary. A decrease in CDAI over time indicates improvement in disease activity.	Baseline and Week 12
Secondary	Percentage of Participants Achieving Clinical Response	Percentage of participants achieving a clinical response as measured by CDAI score (including greater than or equal to [>=] 50, >=70, >=100, and >=150 point reduction from baseline in CDAI) will be reported.	Week 12
Secondary	Percentage of Participants Achieving Clinical Remission	Percentage of participants achieving a clinical remission as measured by CDAI score (CDAI less than [<] 150) will be reported.	Week 12
Secondary	Change from Baseline in the Simple Endoscopic Score for Crohn's disease (SES-CD) at Week 12	Change from baseline in the SES-CD score at Week 12 will be reported. The SES-CD score is based on the evaluation of 4 endoscopic components (presence/size of ulcers, proportion of mucosal surface covered by ulcers, proportion of mucosal surface affected by any other lesions, and presence/type of narrowing/strictures) across 5 ileocolonic segments. Each endoscopic component is scored from 0 to 3 for each segment, and a total score is derived from the sum of all the component scores (range, 0 to 56).	Baseline and Week 12
Secondary	Percentage of Participants Achieving an Endoscopic Response	Percentage of participants achieving an endoscopic response defined as at least a 50% improvement from baseline in the SES-CD.	Week 12
Secondary	Percentage of Participants Achieving an Endoscopic Remission	Percentage of participants achieving an endoscopic remission defined as an SES-CD score less than or equal to (<=) 2.	Week 12
Secondary	Change From Baseline in Abdominal Pain (AP)	Change in AP from baseline based on a 0 to 10 numerical rating scale (NRS) will be reported. A score of 0 represents "no abdominal pain" and a score of 10 represents the "worst possible AP," with greater scores indicating greater pain severity and intensity.	Baseline up to Week 12
Secondary	Percentage of Participants Achieving Patient-Reported Outcome (PRO)-2 Remission	Percentage of participants achieving a PRO-2 remission defined as AP mean daily score (AP component of the CDAI score) at or below 1 and stool frequency (SF) mean daily score at or below 3, that is, AP <=1 and SF <=3.	Week 12
Secondary	Serum Concentrations of JNJ-64304500	Serum concentrations of JNJ-64304500 will be reported.	Up to Week 26
Secondary	Number of Participants with Antibodies to JNJ-64304500	Antibody titers binding to JNJ-64304500 in positive samples will be reported.	Up to Week 26
Secondary	Number of Participants with Neutralizing Antibodies to JNJ-64304500	Number of participants receiving at least one dose of JNJ-64304500 with neutralizing antibodies to JNJ-64304500 will be summarized.	Up to Week 26
Secondary	Change in Pharmacodynamics (PD) Biomarker Levels of C-Reactive Protein (CRP) from Baseline Compared with Placebo	Change in PD biomarker levels of CRP from baseline compared with placebo will be reported.	Baseline, up to Week 26
Secondary	Change in PD Biomarker Levels of Fecal Calprotectin from Baseline Compared with Placebo	Change in PD biomarker levels of fecal calprotectin from baseline compared with placebo will be reported.	Baseline, up to Week 26
Secondary	Change in PD Biomarker Levels of Fecal Lactoferrin from Baseline Compared with Placebo	Change in PD biomarker levels of fecal lactoferrin from baseline compared with placebo will be reported.	Baseline, up to Week 26
