j. Ascites requiring active medical management including paracentesis;
k. Hyponatremia (defined as serum sodium value of < 130 mEq/L);
l. Female patients who are pregnant or lactating;
m. Patients who are unwilling to follow strict contraception requirements (including 2 reliable methods in combination: one non-hormonal, highly-reliable method [diaphragm, condoms with spermicidal foam or jelly, or sterilization] plus one additional reliable method [birth control pills, intrauterine device, contraceptive injections, or contraceptive patches]) before entry and throughout the study, up to and including the 30-day nontreatment follow-up period;
n. Female patients with reproductive potential who do not have a negative urine pregnancy test at Screening;
o. Major surgery without full recovery or major surgery within 3 weeks of Screening;
p. Uncontrolled hypertension (defined as a systolic pressure ≥ 160 mmHg and/or a diastolic pressure ≥ 110 mmHg);
q. New onset seizures (within 3 months prior to the first dose of rigosertib) or poorly controlled seizures;
r. Any other concurrent investigational agent or chemotherapy, radiotherapy, or immunotherapy;
s. Chronic use (> 2 weeks) of corticosteroids (> 10 mg/24 hr equivalent prednisone) within 4 weeks of Screening;
t. Investigational therapy within 4 weeks of Screening;
u. Psychiatric illness or social situation that would limit the patient’s ability to tolerate and/or comply with study requirements.

E.5 End points |
E.5.1 | Primary end point(s) |
Haematological improvement will be assessed according to the 2006 IWG criteria to include:
1. RBC transfusion independence, ie no RBC transfusions administered over a period of 8 consecutive weeks.
2. erythroid response, ie transfusion reduction of at least 4 RBC units over 8 weeks after Baseline/First Dose compared to the number of transfusions in the 8 weeks before treatment
3. neutrophil or platelet response
|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
1. RBC transfusion independence and 2. erythroid response:
transfusion history to be recorded at screening, baseline (Day 1) and weekly throughout study for a maximum period of 48 weeks.
3. neutrophil or platelet response: complete blood count will be measured at screening, baseline (Day 1) and every week throughout study. |
|
E.5.2 | Secondary end point(s) |
Efficacy response will be assessed according to the following outcomes:
1. Number and dates of transfusions of red blood cell (RBC) units
2. Hgb values before each RBC transfusion
3. Number and dates of transfusions of platelet (PLT) units
4. Platelet counts before each PLT transfusion
5. Overall survival
6. Blastic response in bone marrow (BM)
7. Change in BM cytogenetics
8. Changes in Hgb and in RBC transfusion requirements
9. Changes in absolute neutrophil count (ANC)
10. Changes in PLT count and PLT transfusion requirements
Safety will be assessed as treatment emergent adverse events |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
1, 3: Transfusion history to be recorded at screening, baseline (Day 1) and weekly throughout study;
2, 4, 8, 9, 10: Complete blood count will be measured at screening, baseline (Day 1) and every week throughout study;
5: throughout study
6: Bone marrow aspirate and/or biopsy will be performed at screening and for patients with more than 5% pre-treatment BMBL every 15 weeks throughout study;
7: Bone marrow cytogenetics will be performed at screening and if abnormal will repeated every 15 weeks throughout study
Safety will be monitored throughout study |
