Detaljeret beskrivelse
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)

|---|---|
|
Eksperimentel: 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. |

Eksperimentel: Stratum II
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). |

Salvage treatment for risk LCH To assess the efficacy of the combination 2-CdA/Ara-C (Cytosine Arabinoside and 2-chlorodeoxyadenosine) in MS-LCH (patients with risk organ involvement, who fail to respond to front-line (Stratum I) therapy. The initial therapy consists of 2 courses of 2-CdA/Ara-C. Continuation of outlined treatment to be assessed at assigned intervals in each stratum. |

Eksperimentel: Stratum IV
To determine the overall and disease free survival at 1 and 3 years after reduced intensity conditioning hematopoietic stem cell transplantation (RIC-HSCT). Salvage treatment option for MS-LCH patients with risk organ involvement, who fail to respond to front-line therapy (Stratum I) OR to the salvage 2- CdA/Ara-C regimen (Stratum III). |

Eksperimentel: Stratum V
Stratum V Monitoring and Treatment of isolated tumorous and neurodegenerative CNS-LCH - Special regimens will be offered to patients with isolated tumorous CNS-LCH (repeated 2-CdA courses) and to patients with clinically manifested ND-CNS-LCH (+/- extracranial LCH manifestations). For the last group monotherapy with Ara-C courses or (Intravenous immunoglobulin)IVIG will be offered depending on physician's choice. |
