A Study of Oral Foralumab in Participants With Moderate to Severely Active Crohn's Disease

Phase 1

Withdrawn

• Conditions: Crohn's Disease
• Interventions: Drug: Foralumab

• Registration Number: NCT05028946
• Lead Sponsor: Tiziana Life Sciences LTD

Brief Summary

The primary objective of this study is to establish the safety and tolerability of multiple ascending doses (MAD) of foralumab enteric coated capsules administered orally, once daily for 5 days per week over 2 weeks in participants with moderate to severely active Crohn's Disease (CD).

Detailed Description

Four different doses of foralumab enteric coated capsules will be studied for safety and tolerability in a MAD format. Participants in the sequential MAD cohorts will receive treatment when the safety data of one cohort are reviewed by the Data Safety Monitoring Board (DSMB) and are deemed favorable to proceed with the next treatment in the subsequent cohort.

Primary Outcome Measures

Name	Time	Method
Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs)	Day 1 up to Day 14	Adverse events categorized and graded via CTCAE

Secondary Outcome Measures

Name	Time	Method
Change From Baseline in Crohn's Disease Activity Index (CDAI) Score at Day 5 and Day 12	Baseline, Day 5 and Day 12	The CDAI score is used to quantify the symptoms of participants with Crohn's Disease. CDAI scores generally range from 0 to 600 points. A score of 150 or below indicates remission and a score above 450 indicates extremely severe disease. A decrease in CDAI over time indicates improvement in disease activity.
