Summary
Abiraterone Acetate 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 2 registered trials linking Abiraterone Acetate to Colorectal Cancer: 1 is active or not yet recruiting; 1 has completed. The most advanced is Phase 1 (NCT03170960). It plans or enrolled 914 participants. Registration activity spans 2016 to 2017. No published literature item is linked to Abiraterone Acetate and Colorectal Cancer 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 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trial scores by status (recruiting / active / enrolling 3, completed 2.5, not yet recruiting 2, unknown 1, terminated / withdrawn / suspended 0.5) plus a phase bonus (phase 3-4 +2, phase 2 +1, phase 1 +0.5).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.
Registered clinical trials
| NCT ID | Title | Status | Phase | Enrolment |
|---|---|---|---|---|
| NCT03170960 | Study of Cabozantinib Alone or in Combination With Atezolizumab to Subjects With Locally Advanced or Metastatic Solid Tumors 2017 | active, not recruiting | Phase 1 | 914 |
| NCT02740985 | A Phase 1 Clinical Study of AZD4635 in Patients With Advanced Solid Malignancies 2016 | completed | Phase 1 | 313 |

Mechanism and notes
Recorded mechanism or class: inhibitor.
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 APC. The tier describes how well the drug-disease link is documented, not how well the drug works.
Frequently asked questions
Is Abiraterone Acetate approved for Colorectal Cancer?
Abiraterone Acetate 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 Abiraterone Acetate in clinical trials for Colorectal Cancer?
ClinicalTrials.gov lists 2 registered trials linking Abiraterone Acetate to Colorectal Cancer: 1 is active or not yet recruiting; 1 has completed. The most advanced is Phase 1 (NCT03170960). It plans or enrolled 914 participants. Registration activity spans 2016 to 2017.
What does the evidence show for Abiraterone Acetate in Colorectal Cancer?
Abiraterone Acetate has 1 completed registered trial for Colorectal Cancer 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 APC. The tier describes how well the drug-disease link is documented, not how well the drug works.
