LCH-IV, protocollo internazionale di trattamento collaborativo per bambini e adolescenti con istiocitosi a cellule di Langerhans

9 novembre 2026 aggiornato da: North American Consortium for Histiocytosis

Descrizione dettagliata

The international efforts of the past 20 years have shown that combination therapy with vinblastine and prednisone is an effective therapy for Multi-system (MS)-LCH. The previous prospective trial LCH-III confirmed this regimen as a standard regimen for MS-LCH in patients with and without risk organ involvement. It also showed that prolonged treatment in the latter group (treatment duration of 12 vs. 6 months) is superior in preventing disease reactivations. The results of this trial are encouraging and serve as a basis for the LCH-IV study design.Due to the complexity of the disease presentations and outcomes, the LCH-IV study seeks to tailor treatment based on features at presentation and on response to treatment, leading to seven strata:

  • Stratum I: First-line treatment for MS-LCH patients (Group 1) and patients with Single system (SS)-LCH with multifocal bone or "Central Nervous System (CNS)-risk" lesions (Group 2)
  • Stratum II: Second-line treatment for non-risk patients (patients without risk organ involvement who fail first-line therapy or have a reactivation after completion of first-line therapy)
  • Stratum III: Salvage treatment for risk LCH (patients with dysfunction of risk organs who fail first-line therapy)
  • Stratum IV: Stem cell transplantation for risk LCH (patients with dysfunction of risk organs who fail first-line therapy)
  • Stratum V: Monitoring and treatment of isolated tumorous and neurodegenerative CNS-LCH
  • Stratum VI: Natural history and management of "other" SS-LCH (patients who do not need systemic therapy at the time of diagnosis)
  • Stratum VII: Long-term Follow up (all patients irrespective of previous therapy will be followed for reactivation or permanent consequences once complete disease resolution has been achieved and the respective protocol treatment completed)

Armi e interventi

Gruppo di partecipanti / Arm
Intervento / Trattamento
Sperimentale: Stratum I

Stratum I The combination of Prednisone and vinblastine is the standard first-line combination for patients needing systemic therapy (Stratum I). Patients with MS-LCH and involvement of risk organs, who do not respond to 6-12 weeks of standard therapy, will be immediately switched to alternative treatment approaches (Stratum III or Stratum IV).

Further therapy prolongation (12 vs. 24 months) and intensification (± mercaptopurine) will further reduce the reactivation rate and the permanent consequences.

A uniform "intensive" 24-week course consisting of prednisolone, vincristine and cytosine-arabinoside will be introduced in Stratum II for eligible patients. It will be followed by a continuation therapy to total treatment duration of 24 months. Participants who after SL-IT (week 24) have a response (NAD or AD better) are eligible for randomization between the continuation arms "INDOMETHACIN" and "6-MP/MTX" (mercaptopurine and Methotrexate).
