Patients who have not consented to the following contraceptive measures.
Patients will avoid sexual intercourse with sexual partners or should use the following contraceptive methods in these time periods: for male patients during the administration period of the trial and for six months after the end of administration; female patients during the administration period of the trial, and until a second menstrual period is confirmed after the end of administration (or in the case of female patients with no menstrual period, for two months after the end of administration).
•Male patients
The patient will always use a condom. For effective contraception, it is recommended that the female partner also use the contraceptive methods for female patients.
•Female patients
Female patients who may become pregnant should use one or more types of the following contraceptive methods. In addition, the male partner will always use a condom.
- Oral contraceptive (birth control pills)
- Intrauterine device (IUD)
- Tubal ligation

Intervention / Treatment |
---|---|
Experimental: SyB L-1101
In Cohort 1, SyB L-1101 1200 mg/day group, Participants were administered 1200 mg/day of SyB L-1101 intravenously for 3 consecutive days, followed by 11-day observation period. In Cohort 2, SyB L-1101 1800 mg/day group, Participants were administered 1800 mg/day of SyB L-1101 intravenously for 3 consecutive days, followed by 11-day observation period. For both Cohorts, the treatment period of 14 days constitutes 1 cycle, and the treatment was allowed for up to 8 cycles. |
SyB L-1101(rigosertib sodium) will be administered to two cohorts at either 1200 mg/day or 1800 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. |
