Summary
Irinotecan Hydrochloride has reached the approved stage (maximum clinical phase 4) for at least one indication, so its use in Inflammatory Bowel Disease (Crohn's / UC) would be drug repurposing rather than first-in-human development. This does not mean it is approved for Inflammatory Bowel Disease (Crohn's / UC). ClinicalTrials.gov lists 1 registered trial linking Irinotecan Hydrochloride to Inflammatory Bowel Disease (Crohn's / UC): 1 has completed. The most advanced is Phase 4 (NCT01588990). It plans or enrolled 128 participants. Registered activity dates to 2012. No published literature item is linked to Irinotecan Hydrochloride and Inflammatory Bowel Disease (Crohn's / UC) in the OSMF database yet, so the record rests on registry entries alone. Registry entries describe intent to study, not outcomes.
The RepurpOS disease-intelligence file for Inflammatory Bowel Disease ranks 200 candidate therapeutics from Open Targets, ChEMBL, DGIdb and PubMed; only a minority carry direct clinical evidence, and this page covers one of those. Spontaneous remission context recorded for the condition: Disease course unchanged in ~85% of patients at 10 years on standard care; ~23% (CD) and ~12% (UC) relapse within 12 months of thiopurine withdrawal in sustained remission.

How the evidence score is calculated
- Each registered trial scores by status (recruiting / active / enrolling 3, completed 2.5, not yet recruiting 2, unknown 1, terminated / withdrawn / suspended 0.5) plus a phase bonus (phase 3-4 +2, phase 2 +1, phase 1 +0.5). The trial component is capped at 30.
- Each literature item scores by design (Cochrane review 5, meta-analysis 4, systematic review 3, RCT 3, clinical trial publication 2, curated reference 1.5, other PubMed record 1). The literature component is capped at 30.
- The existing evidence tier adds 15 (A / Strong), 10 (B / Moderate), 5 (C / Preliminary) or 0 (D / Anecdotal).
- Agents approved for any indication (max clinical phase 4) add 5, because an approved agent has an established safety profile that lowers the barrier to repurposing trials.
- The score ranks what has been studied, not what works. It does not read effect sizes or directions of effect.
Registered clinical trials
| NCT ID | Title | Status | Phase | Enrolment |

| NCT01588990 | A Translational Study of Bevacizumab in Participants With Metastatic Colorectal Cancer 2012 | completed | Phase 4 | 128 |
Published literature
No publication is linked to this pair yet.
Mechanism and notes
No mechanism of action is recorded for this pair in the source databases.
OSMF's existing evidence tier for this pair is A (Strong), derived from the strength of the disease association recorded in DGIdb, in this case via the biomarker or target ALOX5. The tier describes how well the drug-disease link is documented, not how well the drug works.
Frequently asked questions
Is Irinotecan Hydrochloride approved for Inflammatory Bowel Disease (Crohn's / UC)?
Irinotecan Hydrochloride has reached the approved stage (maximum clinical phase 4) for at least one indication, so its use in Inflammatory Bowel Disease (Crohn's / UC) would be drug repurposing rather than first-in-human development. This does not mean it is approved for Inflammatory Bowel Disease (Crohn's / UC). Approval status for the specific indication should always be confirmed with the relevant regulator and prescribing information.
Is Irinotecan Hydrochloride in clinical trials for Inflammatory Bowel Disease (Crohn's / UC)?
ClinicalTrials.gov lists 1 registered trial linking Irinotecan Hydrochloride to Inflammatory Bowel Disease (Crohn's / UC): 1 has completed. The most advanced is Phase 4 (NCT01588990). It plans or enrolled 128 participants. Registered activity dates to 2012.
What does the evidence show for Irinotecan Hydrochloride in Inflammatory Bowel Disease (Crohn's / UC)?
Irinotecan Hydrochloride has 1 completed registered trial for Inflammatory Bowel Disease (Crohn's / UC) but no linked publication, which usually means results are unpublished, pending, or not yet matched to this record. OSMF's existing evidence tier for this pair is A (Strong), derived from the strength of the disease association recorded in DGIdb, in this case via the biomarker or target ALOX5. The tier describes how well the drug-disease link is documented, not how well the drug works.
