Summary
Tacrolimus Anhydrous has reached the approved stage (maximum clinical phase 4) for at least one indication, so its use in Lupus Nephritis would be drug repurposing rather than first-in-human development. This does not mean it is approved for Lupus Nephritis. ClinicalTrials.gov lists 8 registered trials linking Tacrolimus Anhydrous to Lupus Nephritis: 4 have completed; 4 are terminated, withdrawn, suspended or of unknown status. The most advanced is Phase 4 (NCT01316133). The largest enrolment is 1200 participants (NCT03791827). Registration activity spans 2005 to 2023. No published literature item is linked to Tacrolimus Anhydrous and Lupus Nephritis 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 Lupus Nephritis 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: Spontaneous remission essentially zero in class III/IV LN; progression to ESRD in 10-20% at 10 years on standard therapy; renal flares in 30-50% of patients achieving initial response.

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scores by status (recruiting / active / enrolling 3, completed 2.5, not yet recruiting 2, unknown 1, terminated / withdrawn / suspended 0.5) plus a phase bonus (phase 3-4 +2, phase 2 +1, phase 1 +0.5).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

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 ACKR2. The tier describes how well the drug-disease link is documented, not how well the drug works.
Frequently asked questions
Is Tacrolimus Anhydrous approved for Lupus Nephritis?
Tacrolimus Anhydrous has reached the approved stage (maximum clinical phase 4) for at least one indication, so its use in Lupus Nephritis would be drug repurposing rather than first-in-human development. This does not mean it is approved for Lupus Nephritis. Approval status for the specific indication should always be confirmed with the relevant regulator and prescribing information.
Is Tacrolimus Anhydrous in clinical trials for Lupus Nephritis?
ClinicalTrials.gov lists 8 registered trials linking Tacrolimus Anhydrous to Lupus Nephritis: 4 have completed; 4 are terminated, withdrawn, suspended or of unknown status. The most advanced is Phase 4 (NCT01316133). The largest enrolment is 1200 participants (NCT03791827). Registration activity spans 2005 to 2023.
What does the evidence show for Tacrolimus Anhydrous in Lupus Nephritis?
Tacrolimus Anhydrous has 4 completed registered trials for Lupus Nephritis 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 ACKR2. The tier describes how well the drug-disease link is documented, not how well the drug works.
