Summary
Epirubicin has reached the approved stage (maximum clinical phase 4) for at least one indication, so its use in Chronic Lymphocytic Leukaemia (CLL) would be drug repurposing rather than first-in-human development. This does not mean it is approved for Chronic Lymphocytic Leukaemia (CLL). ClinicalTrials.gov lists 1 registered trial linking Epirubicin to Chronic Lymphocytic Leukaemia (CLL): 1 has completed. The most advanced is Phase 2 (NCT00062296). It plans or enrolled 5 participants. Registered activity dates to 2003. No published literature item is linked to Epirubicin and Chronic Lymphocytic Leukaemia (CLL) 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 Chronic Lymphocytic Leukemia ranks 50 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: Early-stage (Rai 0-I): watch-and-wait appropriate in 50-70%; spontaneous remission extremely rare; median time to treatment in Rai Stage 0: 10+ years; Richter's transformation (5-10%) extremely poor prognosis.

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scores by status (recruiting / active / enrolling 3, completed 2.5, not yet recruiting 2, unknown 1, terminated / withdrawn / suspended 0.5) plus a phase bonus (phase 3-4 +2, phase 2 +1, phase 1 +0.5).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

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 Open Targets and ChEMBL, in this case via the biomarker or target ABL1. The tier describes how well the drug-disease link is documented, not how well the drug works.
Frequently asked questions
Is Epirubicin approved for Chronic Lymphocytic Leukaemia (CLL)?
Epirubicin has reached the approved stage (maximum clinical phase 4) for at least one indication, so its use in Chronic Lymphocytic Leukaemia (CLL) would be drug repurposing rather than first-in-human development. This does not mean it is approved for Chronic Lymphocytic Leukaemia (CLL). Approval status for the specific indication should always be confirmed with the relevant regulator and prescribing information.
Is Epirubicin in clinical trials for Chronic Lymphocytic Leukaemia (CLL)?
ClinicalTrials.gov lists 1 registered trial linking Epirubicin to Chronic Lymphocytic Leukaemia (CLL): 1 has completed. The most advanced is Phase 2 (NCT00062296). It plans or enrolled 5 participants. Registered activity dates to 2003.
What does the evidence show for Epirubicin in Chronic Lymphocytic Leukaemia (CLL)?
Epirubicin has 1 completed registered trial for Chronic Lymphocytic Leukaemia (CLL) 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 Open Targets and ChEMBL, in this case via the biomarker or target ABL1. The tier describes how well the drug-disease link is documented, not how well the drug works.
