Collagenase Clostridium Histolyticum: From Dupuytren’s Contracture to Ledderhose Disease
One-Sentence Summary
Collagenase Clostridium Histolyticum (CCH) is a bacterial collagenase enzyme recognized internationally for treating Dupuytren’s contracture (palmar fibromatosis), though no US market licenses were retrieved in this database query. The TxGNN model predicts it may also be effective for Ledderhose disease (plantar fibromatosis), supported by 3 published case reports and an indirect clinical trial in the same fibromatosis family. Separately, the model identified palmar fibromatosis (Dupuytren’s contracture) as a high-confidence secondary prediction — supported by 32 clinical trials and 20 publications — consistent with CCH’s globally established mechanism.

⚠️ Database Note: The data pipeline returned 0 US records for CCH. However, CCH (Xiaflex®) is known to have received FDA approval for Dupuytren’s contracture in 2010 and Peyronie’s disease in 2013. This likely reflects a data retrieval gap. Verify via FDA Orange Book before making regulatory decisions.
Why is This Prediction Reasonable?
CCH consists of two highly selective bacterial collagenases (AUX-I and AUX-II) derived from Clostridium histolyticum, which specifically degrade types I and III collagen — the dominant structural proteins in pathological fibrous cords. In Dupuytren’s contracture, CCH disrupts the collagen-rich cords that form in the palmar fascia, allowing passive finger extension and restoring hand function without surgery.
Ledderhose disease (plantar fibromatosis) is a fibroproliferative disorder of the plantar fascia that shares nearly identical histopathology with Dupuytren’s contracture: abnormal myofibroblast proliferation, excessive type I and III collagen deposition, and formation of fibrotic nodules within fascial tissue. The critical difference is only anatomical — plantar (foot sole) versus palmar (hand palm). Since the collagen composition of pathological cords is the same in both conditions, CCH’s enzymatic mechanism should be equally applicable to plantar fibromatosis nodules.
Published case reports (see Literature Evidence) have already demonstrated that off-label CCH injection can reduce plantar fibromatosis nodule size with favorable short-term outcomes. Furthermore, CCH has proven efficacy in Peyronie’s disease (penile fibromatosis) — a third fibromatosis condition — reinforcing that CCH’s mechanism generalizes across anatomically distinct fibroproliferative disorders. TxGNN’s prediction aligns directly with this mechanistic logic.

Safety Considerations
No safety data was retrieved from the database for this drug. Please refer to the package insert for full safety information.
Based on published clinical literature, the following safety signals are documented:
- Local site reactions: Swelling, ecchymosis, pain, and tenderness at injection site are extremely common (>90% in clinical trials) but typically resolve within 1–2 weeks
- Skin laceration: Spontaneous skin tears during manual extension maneuver reported; risk management requires careful technique (PMID 29570549)
- Tendon rupture / ligament injury: Rare but serious; reported in Phase 3 trials and post-marketing surveillance
- Antithrombotic drug interaction: A dedicated study (PMID 34789118, N=148) found no significant increase in complications for patients on antithrombotic therapy, though bruising may be more pronounced
Conclusion and Next Steps
Decision: Proceed with Guardrails
Rationale: CCH’s mechanism of collagen I/III degradation is directly relevant to Ledderhose disease, which shares identical fibroproliferative pathology with Dupuytren’s contracture at a different anatomical site. Published case reports confirm clinical feasibility, and the drug’s extensive Phase 3 safety and efficacy data from Dupuytren’s and Peyronie’s disease provides a strong mechanistic and safety foundation for clinical translation to plantar fibromatosis.
To proceed, the following is needed:
- Dedicated clinical trial: A prospective Phase 2 trial of CCH specifically for Ledderhose disease is the critical next step — no such trial currently exists
- Dosing and delivery optimization: The plantar fascia differs anatomically from the palmar fascia; injection depth, volume, and manipulation technique require adaptation and formal study
- US regulatory database verification: Confirm whether CCH (Xiaflex®) holds current FDA approval — the database returned 0 records, which is likely a data pipeline issue given known FDA approval history
- MOA documentation: Formal mechanism of action data is marked as a data gap in this Evidence Pack; complete this for regulatory submissions
- Safety assessment for plantar route: Post-injection weight-bearing restrictions, footwear accommodations, and recurrence monitoring protocols are needed
⚠️ False Positive Alert — Ranked Predictions #1–3, #7–9: The TxGNN model scored several platelet and coagulation disorders (primary release disorder of platelets, Glanzmann thrombasthenia, pseudo-von Willebrand disease, hemorrhagic disorder due to constitutional thrombocytopenia, Scott syndrome) with high scores. These predictions are mechanistically implausible — CCH degrades extracellular collagen and has no known pathway to platelet granule secretion, GPIIb/IIIa function, or phospholipid membrane asymmetry. They are assessed as model false positives arising from indirect knowledge graph links between collagen and platelet activation. Prediction #9 (bleeding diathesis due to collagen receptor defect) warrants particular caution: CCH degrades the collagen substrate that platelet receptors bind to, which could theoretically worsen bleeding in this population rather than treat it. None of these platelet/coagulation predictions should be advanced.
