简要总结
This is a prospective, randomized, sequential, international, multicentric, 2-arm, non-comparative, open-label, 2-stage clinical study to determine disease response rates to Velcade™ therapy in subjects who have relapsed or refractory follicular B-cell lymphoma.
Qualitative comparisons of the 2 treatment arms based on safety, efficacy and dosing convenience will be made in order to recommend a dose schedule for further clinical study.
详细描述
This is a prospective, randomized, sequential, international, multicentric, 2-arm, non-comparative, open-label, 2-stage clinical study to determine disease response rates therapy of Velcade™ in subjects who have relapsed or refractory follicular B-cell lymphoma (FLL).
Qualitative comparisons of the 2 treatment arms based on safety, efficacy and dosing convenience will be made in order to recommend a dose schedule for further clinical study.
It is anticipated that approximatively 120 subjects will be enrolled to achieve the required 110 evaluable subjects, 55 in each treatment arm. Patients who receive any amount of Velcade™ are evaluable. Subjects not evaluable for response will be replaced.
A central randomization will be used in this study. Subjects will be randomized and stratified with factors for prior therapies (1 or 2 versus > 2) and time to progression (TPP) for the last given anti-neoplastic therapy (≤ 12 months versus > 12 months).
The eligible subjects will be randomized to either Treatment Arm A or Treatment Arm B in a 1:1 ratio:

入选标准
- •Male or female subject 18 years or older.
- •Initial diagnosis of follicular B-cell lymphoma (CD20+) (grades 1, 2, and 3 based on the World Health Organization 1997 classification), in first or subsequent relapse or progression after prior anti-neoplastic treatment including previous rituximab treatment. Relapse or progression since previous anti-neoplastic therapy must be documented by new lesions or objective evidence of progression of existing lesions.
- •At least 1 measurable lymph node mass that is >1.5 cm in 2 perpendicular dimensions, and has not been previously irradiated or has grown since previous irradiation.
- •No active central nervous system (CNS) lymphoma
- •Karnofsky Performance Status (KPS) >50% (Eastern Cooperative Oncology Group [ECOG] 0-2)
- •The following laboratory values at screening, unless abnormalities are related to the lymphoma:
- •Absolute neutrophil count (ANC) >1000 cells/dL;
- •Platelets >50,000 cells/dL;
- •Aspartate transaminase (AST) <3 x upper limit of normal (ULN);
- •Alanine transaminase (ALT) <3 x ULN;
- •Total bilirubin <2 x ULN;
- •Creatinine level <150 µmol/L
- •Toxic effects of previous therapy or surgery resolved to Grade 2 or better.
- •Female subject is either post-menopausal or surgically sterilized or willing to use an acceptable method of birth control (i.e., a hormonal contraceptive, intra-uterine device, diaphragm with spermicide, condom with spermicide, or abstinence) for the duration of the study. Women are neither breast feeding nor pregnant for the duration of the study. Confirmation that the subject is not pregnant must be established by a negative serum beta-human chorionic gonadotropin pregnancy test result obtained during screening. Pregnancy testing is not required for post-menopausal or surgically sterilized women. Male subject agrees to use an acceptable method of contraception for the duration of the study.
- •Voluntary signed informed consent before performance of any study-related procedure not part of normal medical care.
- •Patient with minimum life expectancy of 3 months.
排除标准
- •Any other type of lymphoma.
- •Previous treatment with Velcade™.
- •Anti-neoplastic or experimental or radiation therapy within 3 weeks before Day 1 of Cycle
- •Major surgery within 2 weeks before Day 1 of Cycle
- •Rituximab, alemtuzumab (Mabcampath®), or other unconjugated therapeutic antibody within 10 weeks before Day 1 of Cycle
- •Nitrosoureas within 6 weeks before Day 1 of Cycle
- •Radioimmunoconjugates or toxin immunoconjugates such as ibritumomab tiuxetan (Zevalin™), or tositumomab (Bexxar®) within 10 weeks before Day 1 of Cycle
- •Peripheral neuropathy or neuropathic pain of Grade 3 or worse.
- •History of allergic reaction attributable to compounds containing boron or mannitol.
- •Diagnosed or treated for a malignancy other than non-Hodgkin's lymphoma (NHL) within 5 years before Day 1 of Cycle 1, with the exception of complete resection of basal cell carcinoma, squamous cell carcinoma of the skin, or in situ malignancy.
- •Active systemic infection requiring treatment.
- •Previously known HIV positive serology.
- •Serious medical or psychiatric illness likely to interfere with participation in this clinical study.
- •Concurrent treatment with another investigational agent.
- •Adult patient under guardian.
