A Study of Improving the Efficacy of Treatment in High Risk T Cell Lymphoma Patients

Study Overview
=================
Brief Summary
-----------------
This is a prospective , open, multicenter, randomized phase III study. The investigators planed to include 380 untreated high risk T cell lymphoma adults,to random to CHOP and c-ATT regimen groups after signature the informed consents. The patients will receive safety assessment every cycles, and efficacy evaluation every 3 cycles. Every-two-months follow up will be received after finishing the treatment.

Detailed Description
-----------------
This is a prospective , open, multicenter, randomized phase III study. We planed to include 380 untreated high risk T cell lymphoma adults,to random to CHOP and c-ATT regimen groups after signature the informed consents. The patients will receive safety assessment every cycles, and efficacy evaluation every 3 cycles. Every-two-months follow up will be received after finishing the treatment. randomization Subjects will be randomly assigned to 1 of 2 treatment groups based on a computer-generated randomization schedule prepared before the study. Dosage and administration Treatment Arm A (CHOP): cyclophosphamide(C), 750mg/m2 for injection on day1; doxorubicin(H), 50 mg/m 2 for injection on day1; and Vincristine(O), 1.4 mg/ m2 for injection on day1, prednisone(P) 60 mg/m2 orally on days 1 to 5. The therapy was repeated every 21 days for a total of 6 cycles. Treatment Arm B (c-ATT):Alternative 3 regimen to be used sequentially(CHOPB→IMVP-16→DHAP).The therapy was repeated every 21 days for a total of 6 cycles. patients with bulky disease or extranodal lesion wil be received radiotherapy after finishing the chemotherapy. Study evaluations Criteria for response categories Tumour response will be evaluated according to the International Workshop to Standardize Response Criteria for Non-Hodgkin's Lymphomas(1998) Efficacy Criteria Disease-free survival Disease-free survival for patients in CR or CRu is measured from the first assessment that documents that response to the date of disease progression or the most recent follow-up visit time. Response rate Response rate is defined as the proportion of subjects who achieve CR/Cru and PR relative to the total population.Overall survival Overall survival is measured from entry onto the study until death from any cause, or the most recent follow-up visit date Scheduling of tumour assessments Baseline total tumour burden must be assessed within a maximum of 21 days before first dose of treatment.Follow-up tumour evaluations will be performed during the last week of every 3rd cycle. After finishing the therapies, tumor evaluation will be performed every 3 months in the first and second years,following every 6 months after 2years. tumour assessments may be performed by CT/MRI for the internal organs lesion. In case of clinically measurable superficial lesions, accurate evidence should be performed in the original records. Clinical Safety Assessments The following, safety, assessments and procedures will be performed according to the schedule of assessments: A complete medical history (including demographics, smoking history, cancer/treatment history) will be performed at screening. Physical examination* ECG Weight Blood pressure heart rate respiratory rate ECOG Score Infection signs Adverse Events and Serious Adverse Events (SAEs) reported according to NCI-CTC criteria. Patients will be assessed for adverse events at each clinical visit and as necessary throughout the study. Laboratory Safety Assessments The following will be completed according to the schedule of assessments: Hæmoglobin Haematocrit Leucocytes Neutrophils Platelets Serum electrolytes ( K+, Ca++) Serum chemistries (Total bilirubin, ALT [SGPT], AST [SGOT], total protein, albumin, LDH, alkaline phosphatase, urea [BUN], serum creatinine, creatinine clearance). Dipstick urinalysis. In case of a significant finding, a microscopic urinalysis should be performed. Note:Adverse Events and Serious Adverse Events (SAEs) reported according to NCI-CTC criteria(Version 3.0)Patients will be assessed for adverse events at each clinical visit and as necessary throughout the study. Follow-up Patients on the study should be reassessed after completion of treatment at a minimum of every 3 months for 2 years, then every 6 months until the completion of the study.assessment content at follow-up visits should include history, physical examination ,blood picture, Urinalysis,liver and kidney function and tumor assessments. Statistical analyzes The proposed regimen was to be considered worthy for additional investigation in this patient population if a disease control rate of 15% or greater. The total sample size will be about 368 patients (to collect 380 evaluable patients, considering a drop-out rate of around 10%,each group number: 190). Treatment duration was defined as days from the first day of drug administration to the last regulated rest day of the final cycle.,Primary objective is overall survival d. Secondary objectives are response rate, safety and disease free survival Response rate is estimated using the binomial probability and exact 95% confidence intervals (CIs) were provided. disease free survival and overall survival curves are estimated using Kaplan-Meier methodology. Adverse events and laboratory tests graded according to the NCI-CTC AE(Version 3).Adverse events will be assigned preferred terms and categorized into body systems according to the MEDDRA classification of the WHO terminology
