MedDRA Classification |
E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To determine toxicity, antitumor efficacy and outcome of weekly Cisplatin combined with the antivascular targeting agent Combretastatin in patients with advanced or recurrent cervical cancer considered incurable by standard treatment. |
|
E.2.2 | Secondary objectives of the trial |
The primary objective (Phase I) is to establish the maximally tolerated dose (MTD) of Combretastatin combined with weekly Cisplatin in patients with advanced cervical cancer. The secondary objective (Phase II) is to compare the anticancer activity of combined weekly Cisplatin (40 mg/m2) and Combretastatin with standard chemotherapy (Cisplatin 75 mg/m2 every third week). This will be done in a randomized Phase II study. Provided that the experimental arm show sufficient activity in Phase II, the tertiary objective (Phase III) will be to evaluate whether weekly Cisplatin and Combretastatin is superior to standard every third week Cisplatin in terms of survival and health related quality of life (HRQoL). |

Previous radiotherapy more than 3 month ago is allowed. i) For Phase II-III, patients progressing directly during previous chemotherapy or radio-chemotherapy are ineligible. j) Acceptable bone marrow function (leukocytes ³ 3.0x109/L and platelet count 100x109/L). k) ECG without evidence of prior myocardial infarction (e.g., significant Q waves), QTc > 450 msec. or other clinically significant abnormalities. l) Sufficient kidney function with calculated (Cockroft-Gault) GFR > 50 ml/min and no uncontrolled hypokalemia and/or hypomagnesemia. m) Acceptable liver function with bilirubin < 30 μmol/l. m) Patients with childbearing potential must have a negative pregnancy test and should use an effective method of contraception (hormonal anticonception or intrauterine device). n) Written informed consent according to ICH/EU GCP guidelines and regional and national law.

E.5 End points |
E.5.1 | Primary end point(s) |
Phase I As toxicity is the primary endpoint a treatment free interval of at least 2 month from previous chemotherapy, radiotherapy or radio-chemotherapy is required to ensure that toxicity from previous treatment does not interfere with toxicity induced by Cisplatin and Combretastatin.
Successive cohorts of 6 patients will be included in the trial at each dose level. The patients will be replaced, if they go off study before having received the first complete cycle (3 weekly infusions) of chemotherapy for any reason except toxicity. The time window for registration of dose limiting toxicity (DLT) is the first cycle of treatment (3 weekly infusions). Each cohort will be observed for a total of 6 weeks before a new dose level can be opened. However, any new toxicity encountered during subsequent treatment cycles should not be regarded as DLT.
Three dose levels will be investigated. If 1 of 3 patients at a given dose level encounters dose limiting toxicity (DLT) the study proceeds at the same dose level for a total of 6 patients. As soon as more than 2 patients encounters DLT this dose level is declared as maximally tolerated dose (MTD). The dose level immediately below MTD will be declared as the recommended Phase 2 dose (RP2D). Additional dose levels with increments of 9 mg/m2 (free acid dose) of Combretastatin per dose level may be opened if MTD is not reached at the initial three dose levels.
Phase-II Phase II involves an open labeled, stratified and one-to-one randomization between every third week Cisplatin 75 mg/m2 and weekly Cisplatin 40 mg/m2 combined with Combretastatin given at the RP2D dose level. As tumor growth delay rather than tumor regression is anticipated with Combretastatin, the primary endpoint is absence of early progression, defined as absence of objective progression at 6 weeks and confirmed at 12 weeks. Disease status will be assessed according to the "RECIST" criteria. Duration of complete response, partial response and stable disease will also be assessed. The Simon design for randomized Phase II trials will be applied with a total of 36 eligible patients registered in each arm. To guard against ineligible or unevaluable cases, the target accrual is set to 80 patients.
Phase-III Provided that the objectives for Phase II are reached the study may be continued directly as a Phase III study.
As survival is the primary endpoint and progression free survival and health related quality of life are the secondary endpoints, patients with no lesions outside previously irradiated volume are eligible. Patients previously treated with chemotherapy administered either as radiosensitizer or for disseminated are also eligible provided a treatment free interval of at least 6 month is at hand.
Patients will be randomized between every third week Cisplatin 75 mg/m2 and weekly Cisplatin 40 mg/m2 combined with Combretastatin given at the RP2D level.
The exact number of required patients is unknown at present and will be calculated according to the results obtained in Phase II. However, a total of at least 400 patients are most likely required to determine a clinical relevant prolongation of median survival with sufficient power.
The primary endpoint will be overall survival with progression free survival and HRQoL as secondary endpoints. Patient assessment of HRQoL will be obtained by use of a standardized and validated questionnaire (EORTC QoL-C30). The HRQoL data will be evaluated according to the scoring manual of the EORTC Quality of Life Study Group. |
