简要总结
Aim of this trial is to assess the efficacy of new anti-CD20 antibody (GA101) in association with DHAP as induction therapy before high dose chemotherapy BEAM with ASCT in patients with relapsed/refractory DLBCL.
详细描述
This is a prospective, multicenter, single arm, phase II trial in young patients (18-65 years) affected by relapsed/refractory Diffuse Large B-cell Lymphoma (DLBCL) at diagnosis,eligible to high-dose therapy.
Aim of the study is to assess whether the addition of GA101 to DHAP is more promising than standard R-DHAP, as induction therapy before high dose chemotherapy BEAM with ASCT with respect to response.
The study is designed primarily to evaluate the efficacy of GA101-DHAP in patients with DLBCL who have relapsed or are refractory to one chemotherapy regimen and secondarily to assess safety and capability to mobilize peripheral stem cells The study is designed with two stages and with stopping rules after the first stage. In particular, at the end of the first stage, the study will be stopped if the efficacy is too low or if the toxicity, measured during the drug administration period, is too high with respect to pre-defined thresholds. .

- •Normal kidney function (creatinine clearance >= 80 ml/min)
- •Cardiac ejection fraction > 50% (MUGA scan or echocardiography)
- •Normal lung function
- •Absence of active infections
- •Non peripheral neuropathy or active neurological non neoplastic disease of CNS
- •Non major surgical intervention prior 3 months to randomization if not due to lymphoma and/or not other disease life-threatening that can compromise chemotherapy treatment
- •Disease free of prior malignancies other than lymphoma for > 3 years with exception of currently treated squamous cell and basal cell carcinoma of the skin or carcinoma in situ of the cervix or breast
- •Life expectancy > 6 months
- •No psychiatric illness that precludes understanding concepts of the trial or signing ten informed consent
- •Written informed consent
- •Women must be:
- •postmenopausal for at least 1 year (must not have had a natural menses for at least 12 months)
- •surgically sterile (have had a hysterectomy or bilateral oophorectomy, tubal ligation, or otherwise be incapable of pregnancy),
- •abstinent (at the discretion of the investigator/per local regulations), or
- •if sexually active, be practicing a highly effective method of birth control (eg, prescription oral contraceptives, contraceptive injections, contraceptive patch, intrauterine device, double-barrier method (eg, condoms, diaphragm, or cervical cap, with spermicidal foam, cream, or gel, male partner sterilization) as local regulations permit, before entry, and must agree to continue to use the same method of contraception throughout the study. They must also be prepared to continue birth control measures for at least 18 months after terminating treatment.
- •Women of childbearing potential must have a negative serum or urine beta-human chorionic gonadotropin (beta-hCG) pregnancy test at screening
- •Men must agree to use an acceptable method of contraception (for themselves or female partners as listed above) for the duration of the study. Men must agree to use a double barrier method of birth control and to not donate sperm during the study and for 3 months after receiving the last dose of study drug.

- •Performance status > 2 according to ECOG scale if not due to lymphoma
- •Patients who previously received GA101 (obinutuzumab) are excluded.
- •Patient has known or suspected hypersensitivity or intolerance to Rituximab
- •Patient has received an experimental drug or used an experimental medical device within 4 weeks before the planned start of treatment. Concurrent participation in nontreatment studies is allowed, if it will not interfere with participation in this study.
