Trastuzumab for Colorectal Cancer: evidence, trials and status

Trastuzumab has both completed registered trials and synthesis-level publications linked to Colorectal Cancer. That is the strongest profile in this database, but the summaries here do not extract effect sizes, so read the linked reviews for direction and magnitude of benefit.

Summary

Trastuzumab has reached the approved stage (maximum clinical phase 4) for at least one indication, so its use in Colorectal Cancer would be drug repurposing rather than first-in-human development. This does not mean it is approved for Colorectal Cancer. ClinicalTrials.gov lists 8 registered trials linking Trastuzumab to Colorectal Cancer: 2 are currently recruiting; 2 have completed; 4 are terminated, withdrawn, suspended or of unknown status. The most advanced is Phase 3 (NCT05253651). It plans or enrolled 400 participants. Registration activity spans 1999 to 2025. The literature layer holds 16 publications for this pair: 4 Cochrane reviews, 1 meta-analysis, 2 systematic reviews, 4 randomised controlled trial publications and 5 clinical trial publications. Publication years run from 2008 to 2026. Because at least one synthesis-level source exists (systematic review, meta-analysis or Cochrane review), this pair has been assessed beyond single studies, although the synthesis may concern a different indication.

The RepurpOS disease-intelligence file for Colorectal Cancer ranks 1212 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: Essentially zero; 5-year survival stage I: ~90% (resectable); stage IV: ~15% overall, ~20-30% with modern therapy and liver metastasis resection.

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trial scores by status (recruiting / active / enrolling 3, completed 2.5, not yet recruiting 2, unknown 1, terminated / withdrawn / suspended 0.5) plus a phase bonus (phase 3-4 +2, phase 2 +1, phase 1 +0.5).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.

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 ARID1A. The tier describes how well the drug-disease link is documented, not how well the drug works.

Frequently asked questions

Is Trastuzumab approved for Colorectal Cancer?

Trastuzumab has reached the approved stage (maximum clinical phase 4) for at least one indication, so its use in Colorectal Cancer would be drug repurposing rather than first-in-human development. This does not mean it is approved for Colorectal Cancer. Approval status for the specific indication should always be confirmed with the relevant regulator and prescribing information.

Is Trastuzumab in clinical trials for Colorectal Cancer?

ClinicalTrials.gov lists 8 registered trials linking Trastuzumab to Colorectal Cancer: 2 are currently recruiting; 2 have completed; 4 are terminated, withdrawn, suspended or of unknown status. The most advanced is Phase 3 (NCT05253651). It plans or enrolled 400 participants. Registration activity spans 1999 to 2025.
