简要总结
The primary objective of this study is to determine the largest dose of ON 01910.Na (rigosertib sodium) that can be given safely as a 3-day continuous infusion once every 2 weeks (2-week cycle) in patients with advanced cancer.
详细描述
This was an open-label, single-center, dose-escalating Phase I study to determine the Dose-Limiting Toxicities (DLTs) and Recommended Phase 2 Dose (RPTD) of ON 01910.Na (rigosertib sodium) administered as a 3 day continuous intravenous (CIV) infusion every 2 weeks (2-week cycles) to up to 28 patients with advanced cancer (12 to 16 in the dose escalation phase and up to 12 additional patients in the dose confirmation phase). The dosing of rigosertib was based on body surface area (BSA), with a starting dose of 50 mg/m2/24 hour for 3 consecutive days.
In the absence of toxicity after at least a 3-week observation period, rigosertib doses were escalated following a Fibonacci scheme with an initial accelerated dose-escalation phase in which 1-patient cohorts received rigosertib for 3 weeks until drug-related Grade 2 toxicity (according to Common Toxicity Criteria for Adverse Events [CTCAE] v.3), excluding alopecia, occurred, at which time 2 additional patients were added to subsequent cohorts. If none of the 3 patients in the cohort experienced DLTs, the dose was escalated by a half-Fibonacci step. If a DLT was seen in the first patient of a cohort, dosing went back a half-step. The next dose level occurred if no DLT was reported in the 3 patients or if no more than 1 DLT occurred in an expanded cohort of 6 patients. If a DLT was seen in 1 of the 3 patients, 3 additional patients were enrolled in the cohort. If DLTs were seen in 2 of 6 patients in a cohort, dose escalation was stopped.
Once the maximum administered dose (MAD) was attained and the RPTD was determined, the dose escalation phase was considered complete. Up to 12 additional patients with histologically confirmed malignant tumors were tested at the RPTD dose to confirm its appropriateness.
Secondary objectives were to determine the qualitative and quantitative toxicity and reversibility of toxicity of rigosertib administered in this fashion; to investigate the clinical pharmacology of rigosertib when administered in this fashion, including plasma pharmacokinetics at each dose level; to confirm the appropriateness of the RPTD; to document any observed antitumor activity of rigosertib; and, to evaluate the biological effect of rigosertib in biomarkers in serum and/or peripheral blood mononuclear cells.

入选标准
- •Patient must have histologically confirmed malignancy that is metastatic or unresectable and for which standard curative or palliative measures do not exist or are no longer effective.
- •At least 4 weeks since the last dose of other potentially myelosuppressive treatment (at least 6 weeks since last dose of nitrosoureas or mitomycin C) and recovery from manifestations of reversible drug toxicity (except alopecia, stable residual neuropathy, and residual hand and foot syndrome). Among patients with prior doxorubicin chemotherapy, only those with no more than 450 mg/m2 of the drug will be entered. It must be at least 4 weeks since prior chemotherapy or radiation therapy, 6 weeks if the last regimen included nitrosoureas or mitomycin C.
- •Patients with prior radiotherapy are eligible provided that a minimum of 4 weeks have passed and that the maximal area of hematopoietic active bone marrow treated was less than 25%.
- •ECOG performance status <
- •Hgb > 10 gm/dl
- •WBC > 4,000 per microliter
- •Absolute neutrophil count > 1,500 per microliter
- •Platelets >100,000 per microliter
- •Total bilirubin within normal institutional limits
- •AST(SGOT)/ALT(SGPT) values within limits defined by Protocol
- •Creatinine within normal institutional limits or creatinine clearance >60 mL/min/1.73 m2 for patients with creatinine levels above institutional normal.
- •Women of child-bearing potential and men must agree to use adequate contraception.
- •Ability to understand and the willingness to sign a written informed consent document.
- •Inclusion Criteria - Dose Confirmation Phase Same inclusion criteria as in the Dose Escalation phase described above, except Patients must have an ECOG performance of 0 or 1.
排除标准
- •Patients who have had recent major surgery (within the past 14 days), chemotherapy or radiotherapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study or those who have not recovered from adverse events (except alopecia, stable residual neuropathy, and residual hand and foot syndrome) due to previously administered agents.
- •Patients may not be receiving any other investigational agents or concurrent chemotherapy, radiotherapy, hormonal treatments, or immunotherapy while on study.
- •Patients with known or clinical evidence of central nervous system metastasis, except brain metastases that have been previously removed or irradiated and currently have no clinical impact.
- •History of allergic reactions attributed to compounds of similar chemical or biologic composition to ON 01910.Na.
- •The patient should have no major 3rd space fluid, ascites requiring active medical management including paracentesis, peripheral bilateral edema, or hyponatremia (serum sodium value less than 134 Meq/L).
- •Uncontrolled intercurrent illness including, but not limited to ongoing or active infection, bleeding, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
