E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to determine the long-term safety and tolerability of MMB in 3 cohorts of subjects:
•Cohort 1: Subjects who are currently receiving MMB capsules in the CCL09101E study for PMF and post-PV/ET MF without documented progressive disease
•Cohort 2: Subjects who are currently receiving MMB capsules in the YM387-II-02 study for PMF and post-PV/ET MF without documented progressive disease
•Cohort 3: Subjects who are currently receiving MMB tablets in the GS-US-354-0101 study for PV or ET, who complete 24 weeks of treatment and whose disease has not progressed on study. Only the cohort 3 is relevant to EU subjects.
|
|
E.2.2 | Secondary objectives of the trial |
The secondary objective of this study is to determine the long-term efficacy of MMB in these 3 cohorts of subjects. |
|
E.2.3 | Trial contains a sub-study | No |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary endpoint is safety. Safety will be evaluated by the incidence and severity of adverse events and clinical laboratory abnormalities, as defined by CTCAE v4.03. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Monitoring will be conducted on a quarterly basis through month 48 / End of Treatment of the study. Additionally, serious adverse events will be reported as soon as they are raised. |
|
E.5.2 | Secondary end point(s) |
Secondary endpoints are:
•Overall survival (OS): defined as the interval from the first dose of MMB on the previous study until death from any cause
•Progression-free survival (PFS): defined as the interval from the first dose of MMB on the previous study until the first documentation of definitive progressive disease or death due to any cause
•Leukemia free survival: defined as the interval from the first dose of MMB on the previous study until the first documented leukemic transformation or death from any cause
•Rate of RBC transfusion: defined as the average number of RBC units per subject month from the first dose of MMB on the previous study during the study period
Other secondary endpoints specific to Cohorts 1 and 2:
•Duration of splenic response: defined as the interval from the first onset of splenic response (in the previous study or this study) to the earliest date of loss of splenic response which persists for at least 4 weeks or death from any cause. Splenic response is defined as > 50% reduction in palpable splenomegaly of a spleen that is ≥ 10 cm below the LCM at baseline or a spleen that is palpable at > 5 cm below the LCM at baseline becomes not palpable.
•Duration of transfusion independence response: defined as the interval from the first onset date of transfusion independence (in the previous study or this study) to the earliest onset date of transfusion dependence or death from any cause, among those subjects who are transfusion dependent at baseline. Transfusion independence is defined as absence of RBC transfusions for ≥ 8 weeks.
•Duration of anemia response: defined as the interval from the first onset of anemia response (in the previous study or this study) to the earliest date of loss of anemia response which persists for at least 4 weeks or death from any cause. Anemia response is defined as ≥ 2g/dL increase in hemoglobin for baseline transfusion independent subjects with baseline hemoglobin level of < 10g/dL, or becoming transfusion independent for those who were transfusion dependent at baseline for ≥ 8 weeks.
Other endpoints specific to Cohort 3:
•Overall response rate (ORR) : Confirmed ORR is defined as the proportion of subjects with onset of response in the previous study with the 12 week confirmation reached during this study. |
