Clinical Trial Summary

To explore the effectiveness and safety of bortezomib, cyclophosphamide and dexamethasone (BCD regimen) in newly diagnosed idiopathic Multicentric Castleman's disease (iMCD) patients.

Description:

This will be a single center, open-labeled, single arm, phase-II pilot study. The treatment and the response evaluation phase will last from the time of enrollment up to 21 months (evaluation will be carried out every 3 months in the first 9 months and every 6 months from Month 9 to Month 21). The maintenance and follow-up phase to assess for progression of disease will last from 21 months to 45 months after enrollment (evaluation will be carried out every 12 months). The total study duration will be 4 years after the last patient starts study medication.

2. Immunosuppressive or anti-neoplastic drugs within the last 3 months;

3. serious diseases including malignancy;

4. Plan to have babies within 1 year after enrollment (for women and men), or pregnancy / breast-feeding (for women);

5. Known hypersensitivity to study agents;

6. Active infection requiring systemic treatment;

7. Other severe concurrent disease (eg. uncontrolled diabetes, symptomatic coronary heart disease) that is likely to interfere with study procedures or results, or that in the opinion of the investigator would constitute a hazard for participating in this study;

8. Unwilling or unable to provide informed consent;

9. Unwilling to return for follow-up at PUMCH.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Overall response	Overall response is composed by biochemical, lymph node and symptom response, is the primary outcome of this study. According to the CDCN response criteria, an overall CR (complete response) requires a complete biochemical, lymph node, and symptomatic response; and overall PR (partial response) requires nothing less than a PR across all categories, but not meeting criteria for CR; an overall SD (stable disease) requires no PD (progression disease) in any of the categories and not meeting the criteria for CR or PR; an overall PD occurs when any category has a PD.	12 months after the last patient begins study treatment.
Secondary	Time to initial response	defined as the time to achieve the first PR or CR. This outcome can be further divided into time to initial overall response, time to initial symptomatic response, time to initial biochemical response, time to initial lymph node response	12 months after the last patient begins study treatment.
Secondary	Time to best response	defined as the time to achieve the best response (either PR or CR). This outcome can be further divided into time to best overall response, time to best symptomatic response, time to best biochemical response, time to best lymph node response;	12 months after the last patient begins study treatment.
Secondary	Progression-free survival (PFS)	defined as the time to disease PD	12 months after the last patient begins study treatment.
Secondary	Overall survival (OS)	defined as the time to patients' death	12 months after the last patient begins study treatment.
Secondary	Change in PHQ-9 score	PHQ-9 score (Patient Health Questionnaire scale-9) is a nine-item self-administered instrument to assess depressive symptoms which incorporates the DSM-IV (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition) classification for major depressive disorder. Each item is scored 0 - 3, which results in a range of scores between 0 and 27. PHQ-9 scores are interpreted as follows: (1) score <5, no depression; (2) score 5 - 9, mild depression; (3) score 10 - 14, moderate depression; (4) score 15 - 19, moderately severe depression; and (5) score 20 - 27,severe depression.	From Day 1 of the BCD treatment until 12 months after the treatment
Secondary	Change in hemoglobin level	hemoglobin with g/L as unit of measure	From baseline until 12 months after the treatment
Secondary	Change in IL-6 (interleukin-6)	IL-6 level with pg/ml as unit of measure	From baseline until 12 months after the treatment
Secondary	Change in CRP	CRP (c-reactive protein) level with mg/L as unit of measure	From baseline until 12 months after the treatment
Secondary	Change in ESR	ESR (eerythrocyte sedimentation rate) level with mm/h as unit of measure	From baseline until 12 months after the treatment
Secondary	Change in IgG level	IgG (immunoglobin G) level with g/L as unit of measure	From baseline until 12 months after the treatment
Secondary	Change in MCD-related overall symptom score	Change of MCD symptom scores. MCD symptom score (MCD disease related overall symptom score) is a 34-item score based on NCI-CTCAE (V4.0) adverse events. Each item is scored 0-5, which results in a range of scores between 0 and 170. More scores indicate more severe disease activity.	From baseline until 12 months after the treatment
Secondary	Number of participants with treatment-related adverse events as assessed by CTCAE v4.0 ( =1 grade)	Number of participants with treatment-related adverse events as assessed by CTCAE v4.0 (patients with grades =1 would be included)	12 months after the last patient begins study treatment.
Secondary	Number of participants with treatment-related serious adverse events as assessed by CTCAE v4.0 ( =3 grade)	Number of participants with treatment-related serious adverse events as assessed by CTCAE v4.0 (patients with grades =3 would be included)	12 months after the last patient begins study treatment
