Vorinostat in Combination With Chemotherapy in Relapsed/Refractory Solid Tumors and CNS Malignancies

Официальное название

A Phase I Study of Vorinostat in Combination With Vincristine, Irinotecan, and Temozolomide in Children, Adolescents, and Young Adults With Relapsed or Refractory Solid Tumors and CNS Malignancies

Обзор

Investigators are testing new experimental drug combinations such as the combination of vorinostat, vincristine, irinotecan, and temozolomide in the hopes of finding a drug that may be effective against tumors that have come back or that have not responded to standard therapy. The goals of this study are: * To find the highest safe dose of vorinostat that can be given together with vincristine, irinotecan, and temozolomide without causing severe side effects; * To learn what kind of side effects this four drug combination can cause; * To learn about the effects of vorinostat and the combination of vorinostat, vincristine, irinotecan, and temozolomide on specific molecules in tumor cells; * To determine whether the combination of vorinosat, vincristine, irinotecan, and temozolomide is a beneficial treatment.

Подробное описание

This first cycle will be used to determine whether the patient can tolerate the chemotherapeutic backbone without developing a DLT. The baseline disease evaluation will be obtained following hematologic recovery from the first cycle of chemotherapy, after which combination therapy with vorinostat will be given in subsequent cycles (2-12) w/ modifications if needed. Vorinostat dose escalation in subsequent patient cohorts will occur based on DLT to determine a MTD.

Вмешательства

• Препарат Vorinostat
  This is a phase I study of the combination of four drugs: vorinostat, vincristine, irinotecan, and temozolomide. This is called a Phase I study because the goal is to find the highest dose of vorinostat that investigators can give safely when it is used together with the chemotherapy drugs vincristine, irinotecan and temozolomide. Investigators are using vorinostat because it seems to work against cancer in test tubes and animals. It may be most effective when it is given with chemotherapy. The

• Prior therapy: Patients may have received prior therapy with vincristine, irinotecan, or temozolomide. They may not however have received therapy that included a treatment cassette of irinotecan and temozolomide in combination.

• Prior myelosuppressive therapy: Patients must have not received myelosuppressive therapy in 3 weeks or nitrosourea chemotherapy within 6 weeks of initiation of protocol therapy.
• Hematologic growth factor support: Patients may not have received G-CSF within the previous 3 days or peg-filgrastim within the past 7 days.
• Biologic anti-neoplastic therapy: At least 21 days or 5 half-lives (whichever is of longer duration) must have elapsed since the last administration of biologic antineoplastic therapy.
• Radiation therapy: ≥ 14 days since the last dose of local XRT; ≥ 6 months must have elapsed if prior TBI, craniospinal XRT or ≥ 50% radiation of pelvis; ≥ 6 wks must have elapsed if other substantial BM radiation.
• Autologous or allogeneic stem cell transplant: No active graft vs. host disease or need for immunosuppressive therapy. At least 3 months must have passed since neutrophil engraftment.
• Organ function:

Bone marrow function:

• Platelet count greater than or equal to100,000/mcL and no platelet transfusion within prior 7 days.
• Hemoglobin greater than or equal to 8 gm/dL
• Patients with known bone marrow metastatic disease may enroll on the study if they have a peripheral ANC greater than or equal to 750 cells/mcL. They will not be evaluable for hematologic toxicity.

\- Adequate liver function:

• Total bilirubin less than or equal to 1.5x upper limit of normal (ULN) for age.
• SGPT (ALT) less than or equal to 5x ULN
• Serum albumin greater than or equal to 2 gm/dL

\- Adequate renal function:

• Creatinine clearance or glomerular filtration rate >70 ml/min/1.73 m2 or a serum creatinine based on age and gender as follows:

Age Maximum serum creatinine concentration (mg/dL) Male Female 1-<2 years 0.6 0.6 2-<6 years 0.8 0.8 6-<10 years 1 1 10-<13 years 1.2 1.2 13-<16 years 1.5 1.4 greater than or equal to 16 years 1.7 1.4 The threshold creatinine values in this table were derived from the Schwartz formula to estimate glomerular filtration rates (Schwartz et al. J. Peds. 106; 522. 1985) using child length and stature data from the CDC.

\- Informed consent: All patients less than 18 years of age must sign a written informed consent. For patients <18 years of age, a parent or guardian must sign a written informed consent, unless the patient is an emancipated minor. Childhood assent, when appropriate, should be obtained as well per institutional guidelines.
