The purpose of this study is to investigate tolerability when SyB L-1101 is administered intravenously in patients with recurrent/relapsed or refractory myelodysplastic syndrome, to determine the dose-limiting toxicity and maximum tolerated dose, and to estimate the recommended dose for phase II studies. Pharmacokinetics and antitumor effects will also be investigated.

Arms Assigned Interventions
Experimental: SyB L-1101 Drug: SyB L-1101

SyB L-1101(rigosertib sodium) will be administered to two cohorts at either 1,200 mg/day or 1,800 mg/day.

The dose will be administered intravenously for 72 continuous hours (3 days), followed by 11-day observation period. The treatment period of 14 days (3 days of administration + 11 days of observation) constitutes 1 cycle.

The study will involve treatment through the second cycle, but treatment can be continued for 3 or more cycles if conditions for continued administration are satisfied.

    • Patients who have not achieved complete remission, partial remission, or hematologic improvement*
    • Patients with recurrence/relapse after complete remission, partial remission, or hematologic improvement*
    • Patients with intolerability that has led to discontinuation of treatment because of the development of liver dysfunction, kidney dysfunction, etc., after the start of treatment. * Proximate therapeutic efficacy judged under IWG2006 criteria
  4. Patients who have not been treated for four weeks or longer after the end of the previous therapy and who are judged to have no residual effects (antitumor effects) from the previous therapy.

  1. Patients with anemia caused by factors other than MDS (hemolytic anemia, gastrointestinal (GI) bleeding, etc.).
  2. Patients who have undergone treatment for an active malignant tumor within the past year (except basal cell or squamous cell skin cancer or carcinoma in situ of the cervix or breast).
