Lenalidomide: From Multiple Myeloma / MDS(del5q) to Myeloid Leukemia
One-Sentence Summary
Lenalidomide (Revlimid®) is an immunomodulatory imide drug (IMiD) already established for multiple myeloma and transfusion-dependent anemia due to low-risk myelodysplastic syndrome (MDS) with del(5q). The TxGNN model predicts it may also be effective for Myeloid Leukemia, with over 40 clinical trials (including 2 completed Phase 3 RCTs) and 20 publications currently supporting this direction — though a blocking safety data gap (no TFDA/BfArM label data available) means this cannot yet proceed past preliminary safety review.
Quick Overview
| Item | Content |

Why is This Prediction Reasonable?
Structured mechanism-of-action data for lenalidomide is not available in this evidence pack. However, supporting literature (PMID 39881283) indicates lenalidomide acts by binding cereblon (CRBN), recruiting the transcription factors IKZF1/IKZF3, and promoting their ubiquitination and degradation — the pathway underlying both its antimyeloma and antileukemic activity. This is consistent with lenalidomide's classification as an immunomodulatory imide drug (IMiD) rather than a conventional cytotoxic chemotherapy.
Myeloid leukemia (AML) and MDS with del(5q) — lenalidomide's proven original indications — sit on the same disease continuum: low-risk MDS frequently progresses to AML, and both conditions share overlapping clonal myeloid pathobiology and cytogenetic abnormalities (notably chromosome 5 deletions). This biological continuity is the most plausible basis for the TxGNN prediction, and is directly reflected in the trial evidence below, where lenalidomide (often combined with azacitidine) has been repeatedly tested across the MDS–AML spectrum, including in relapsed/refractory AML, post-transplant maintenance, and elderly newly-diagnosed AML.

Germany Market Information
Lenalidomide is currently not marketed in Germany (market status: 未上市). No BfArM authorization records are available in the evidence pack (total_licenses: 0).
Cytotoxicity
Lenalidomide is included here because its established original indication (multiple myeloma) is a hematologic malignancy.

Conclusion and Next Steps
Decision: Hold
Rationale: Efficacy evidence for the myeloid leukemia indication is strong (L1: 2 completed Phase 3 RCTs plus extensive Phase 1/2 trial history and a randomized Phase 2 RCT). However, TFDA/BfArM label data (warnings, contraindications) is marked as a Blocking data gap that explicitly prevents entry into the S1 safety pre-assessment, and the drug is currently not marketed in Germany. The recommendation cannot be upgraded to "Proceed with Guardrails" until baseline safety documentation exists.
To proceed, the following is needed:
- Official TFDA/BfArM package insert (warnings, contraindications, DDI) to unblock the S1 safety evaluation
- Confirmed mechanism-of-action data from DrugBank
- Clarification of route/dosage-form compatibility for the AML/MDS population
- Re-verification of literature/trial matching for lower-confidence predicted indications in this pack (e.g., rank 4 "aregenerative anemia," where cited literature appears mismatched to multiple myeloma/Waldenström studies rather than the stated indication)
