Conditions

Rosai-Dorfman Disease

Brief summary

In patients with Rosai-Dorfman disease (RDD), a treatment regimen of lenalidomide combined with dexamethasone is planned to be used.

Detailed description

Patients received oral lenalidomide 25mg on days 1-21 and dexamethasone 40mg on days 1, 8, 15, 22, in 28-day cycles for 12 total cycles.

Interventions

DRUGLenalidomide

The combination therapy period consists of 12 cycles: Lenalidomide: 25mg, orally, D1-21, every 28 days per cycle. Combined with Dexamethasone: 40mg, orally, D1, 8, 15, 22, every 28 days per cycle. The single-agent maintenance period consists of 12 cycles: Lenalidomide: 25mg, orally, D1-21, every 28 days per cycle. The total treatment duration is 24 cycles or until disease progression, death, or the occurrence of intolerable toxicity.

DRUGDexamethasone

The combination therapy period consists of 12 cycles: Lenalidomide: 25mg, orally, D1-21, every 28 days per cycle. Combined with Dexamethasone: 40mg, orally, D1, 8, 15, 22, every 28 days per cycle.

Design outcomes

Primary

MeasureTime frameDescription
Progression-free survival time (PFS)From enrollment to the end of treatment at 8 weeksPFS defined as the time from RD initiation to first documented disease progression, relapse after RD, death from any cause, or last follow-up.

Secondary

MeasureTime frameDescription
Overall Response Rate (ORR)From enrollment to the end of treatment at 8 weeksThe overall response rate (ORR) was defined as the cumulative proportion of patients attaining either a complete response (CR) or partial response (PR) .
Overall Survival (OS)From enrollment to the end of treatment at 8 weeksOS was measured from RD start to death or last follow-up
Adverse eventsFrom enrollment to the end of treatment at 8 weeksToxicities were recorded and graded per National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 5.0.

Other

MeasureTime frameDescription
Correlation between next-generation sequence (NGS) and therapeutic efficacy/PFSFrom enrollment to the end of treatment at 8 weeksCorrelation between the positivity of NGS in MAPK pathway and therapeutic efficacy/PFS
