简要总结
This open-label study evaluated the safety and efficacy of TSC when dosed concomitantly with the standard of care (radiation therapy and temozolomide) for newly diagnosed glioblastoma in adults. All patients received TSC in the study. The objective of the study was to evaluate the effect of TSC on survival and tumor response in patients with GBM while establishing an acceptable patient risk profile.
详细描述
The overall objectives of this Phase 1/2 clinical study in newly diagnosed GBM patients was to evaluate the safety and tolerability, efficacy, PK profile, PFS/time to disease progression, QoL, and overall survival in adults when TSC is added to the standard of care regimen of radiation therapy and temozolomide. All patients received TSC in this study. The primary objective of the Phase 1 portion of the study was to evaluate the safety (DLT rate) and to define the dosing regimen of TSC for the larger Phase 2 study. The primary clinical endpoint was overall survival at 24 months and patients will be followed for up to 3 years.

- •Sexually active patients must use an acceptable method of contraception while receiving doses of study medication.
- •Females of childbearing potential must have a negative serum or urine pregnancy test at screening and have additional pregnancy tests during study.
排除标准
- •Patient who cannot undergo MRI.
- •Pregnant or lactating.
- •Serious concurrent infection or medical illness that would jeopardize the ability of the patient to receive study treatment with reasonable safety.

研究组 & 干预措施
TSC 0.25 mg/kg for 9 or 18 doses
This was an open-label, sequential-cohort, dose-escalation study in two phases. Phase 1 was a safety run-in evaluating Trans Sodium Crocetinate (TSC) in 3 subjects who received 3 doses per week for 3 weeks (9 doses in total). Phase 2 engaged 56 subjects who received 3 doses per week for 6 weeks (18 doses in total). TSC was consistently dosed at 0.25mg/kg in both phases.
干预措施: Trans Sodium Crocetinate (TSC) (Drug)

Overall Survival
时间窗: 6, 12, 18, 24 months
Participants in phase 2 (18 dose group, 6 weeks treatment with TSC) were monitored for up to 3 years (last follow-up - February 16, 2016). Overall Survival (OS) was defined as the length of time from the date of tumor resection surgery or definitive biopsy to the date of death. The OS analyses were performed using the Kaplan-Meier estimate method. The OS rates at 6, 12, 18 and 24 months were estimated. Median OS values were calculated; a corresponding 95% confidence interval for each median value was determined using a log rank analysis. The length of OS (in months) was calculated as follows: date of death or censored - date of surgery or definitive biopsy / 30.4375.
次要结局
- Progression-Free Survival (PFS)(6,12,18, 24 months)
- Number of Participants With Reduction in Tumor Size, According to Percentage of Tumor Reduction(From Baseline to Week 110)
