TCP Regimen in Newly Diagnosed MCD:a Prospective, Single-center, Single-arm, Phase-II Pilot Trial
- Conditions
- Multicentric Castleman Disease
- Interventions
- Registration Number
- NCT03043105
- Lead Sponsor
- Peking Union Medical College Hospital
- Brief Summary
To explore the effectiveness and safety of thalidomide, cyclophosphamide and prednisone (TCP regimen) in newly diagnosed Multicentric Castleman's disease (MCD) patients.
- Detailed Description
This is a single center, open-labeled , single arm, phase-II pilot study which aims to evaluate the efficacy and safety of thalidomide, cyclophosphamide and prednisone (TCP regimen) in newly diagnosed Multicentric Castleman's disease (MCD) patients.There would be two phases of the study. The treatment and the response evaluation phase will last from the time of enrollment up to 24 months (evaluation will be carried out every 3 months). The follow-up phase to assess for progression of disease will last from 24 months (2 years) to 4 years 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.

Group Intervention Description TCP regimen Thalidomide, cyclophosphamide and prednisone Thalidomide, cyclophosphamide and prednisone （TCP regimen）would be used for newly-diagnosed symptomatic MCD patients
- Primary Outcome Measures
Name Time Method Number of Patients With Durable Tumor and Symptomatic Response From baseline to the time point when a patient achieves treatment response for 24 weeks. Durable tumor and symptomatic response is complete response (CR) + partial response (PR). CR: complete disappearance of all measurable and evaluable disease (eg, pleural effusion) and resolution of baseline symptoms attributed to multicentric Castleman's disease, sustained for at least 18 weeks. PR: \>=50 percent decrease in sum of the product of the diameters of indicator lesion(s), with at least stable disease in all other evaluable disease in the absence of treatment failure sustained for at least 6 months.
- Secondary Outcome Measures
Name Time Method Progression-free Survival From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 36 months Progression-free survival (PFS) is defined as the time to death or treatment failure. Treatment failure is defined as: sustained increase in grade ≥2 disease-related symptoms persisting ≥12 weeks; new disease-related grade ≥3 symptoms; sustained \>1 point increase in ECOG-PS persisting for ≥12 weeks; radiological progression; or initiation of another treatment for MCD.
Overall Survival From date of randomization until the date of death from any cause, assessed up to 36 months. Overall survival, defined as the time to patients' death, is measured.
Change in SF-36 Score From baseline to 24 weeks after treatment. SF-36 score is a self-administered scoring system which reflects a patient's general health status. SF-36 contains 8 dimensions, including physical functioning, role physical, role emotional, vitality, mental health, social functioning, bodily pain, and general health. Each dimension ranges from 0 to 100. Higher scores mean better outcome. SF-36 score at baseline was compared with SF-36 score at 24 weeks.
Number of Participants With Treatment-related Adverse Events as Assessed by CTCAE v4.0 ( ≥1 Grade) From initiation of TCP regimen to 3 months after the end of treatment or to time point of the initiation of second line therapy. Number of participants with treatment-related adverse events as assessed by CTCAE v4.0 (patients with grades ≥1 would be included)
Number of Participants With Treatment-related Serious Adverse Events as Assessed by CTCAE v4.0 ( ≥3 Grade) From initiation of TCP regimen to 3 months after the end of treatment or to time point of the initiation of second line therapy. Number of participants with treatment-related serious adverse events as assessed by CTCAE v4.0 (patients with grades ≥3 would be included)
