简要总结
This study has the following objectives:
Primary Objective
- To evaluate the anti-lymphoma efficacy of daily oral doses of ITF2357 followed by intravenous Mechlorethamine administered to patients with refractory/relapsed Hodgkin's lymphoma.
Secondary Objective
- To evaluate the safety and tolerability of multiple courses of ITF2357 followed by Mechlorethamine in a population of chemotherapy pretreated patients.
详细描述
This is a single-center, open label, phase II study aimed at testing the activity of multiple cycles of ITF2357 followed by Mechlorethamine administered to patients with relapsed/refractory Hodgkin's lymphoma.
Patients will receive a maximum of twelve 3-week cycles of ITF2357 followed by Mechlorethamine according to the following schema:
- ITF2357, 50 mg every 6 hours, per os, days 1 - 3
- Mechlorethamine, 6 mg/sqm, intravenously , day 4 Study therapy will be administered every 21 days as long as there is no evidence of progressive disease or unacceptable adverse events or patient's request to discontinue treatment occurs, but in any case for a maximum of 12 cycles.
Decision regarding the continuation of ITF2357/Mechlorethamine therapy will be made on (i)the basis of tumor reassessment following cycles 2, 6, 9, and 12 and (ii) the occurrence of toxicity. Tumor response will be evaluated according to the International Working Group response criteria HL.
Treatment will be administrated on an outpatient basis and patients will be followed regularly with physical and laboratory tests, as specified in the protocol; in case of hospitalisation, the treatment will be continued or interrupted according to the Investigators' decision.

研究组 & 干预措施
ITF2357
Patients received the following therapy cycle
- ITF2357, 50 mg every 6 hours, per os, days 1 - 3;
- Mechlorethamine, 6 mg/sqm, intravenously , day 4. Therapy was administered every 21 days as long as there was no evidence of progressive disease or unacceptable toxicity, but in any case for a maximum of 12 cycles.
The mean number of complete treatment cycles received by patients was 5.25, with a minimum of 1 cycle and a maximum of 12 cycles.

结局指标
主要结局
Objective Response Rate (ORR)
时间窗: At each 21-day cycle for a maximum of 12 cycles
OR rate among patients treated is defined according to the Revised Response Criteria for Malignant Lymphoma of the International Working Group. In medicine, a response rate is the percentage of patients whose cancer shrinks or disappears after treatment. The FDA definition of ORR is the proportion of patients with tumor size reduction of a predefined amount and for a minimum time period. The tumor objective response rate (ORR) is an important parameter to demonstrate the efficacy of a treatment in oncology. The ORR is valuable for clinical decision making in routine practice and a significant end-point for reporting the results of clinical trials.
Proportion of Responders (Complete -CR- or Partial PR-)
时间窗: At each 21-day cycle for a maximum of 12 cycles
Complete responder (CR) and partial responder (PR) among patients treated are defined according to the Revised Response Criteria for Malignant Lymphoma of the International Working Group. CR is defined as complete disappearance of all detectable clinical evidence of disease and disease-related symptoms if present before therapy. PR is defined as regression of measurable disease and no new sites. The frequencies of patients achieving objective response (i.e. subjects whose best overall response was CR or PR) and the frequencies of patients who did not achieve an objective response (i.e.subjects whose best overall response was equal to stable disease - SD, progressive disease - PD - or not evaluable) in ITT and PP populations are reported. NED= no evidence of disease
次要结局
- Time To Response (TTR)(From the first day of the first cycle until the date of achieving a response assessed up to 250 days from the start of the first cycle of treatment)
- Progression-Free Survival (PFS)(From the first day of the first cycle of treatment until objective tumor progression or death, whichever came first, assessed up to 450 days from the start of the first cycle of treatment)
- Response Duration (RD):(From the first day of the first cycle of treatment until objective tumor progression or death, whichever came first, or last available tumor assessment (assessed up to 350 days from the start of the first cycle of treatment).)
