Nab-paclitaxel in Combination with Gemcitabine for Pediatric Relapsed and Refractory Solid Tumors

Completed · Phase 1

Conditions studied: Cancer

In brief

This is a research study for people who have a solid tumor that was not effectively treated by conventional therapy or for which there is no known effective therapy. This is a phase I study of a drug called nab-paclitaxel used together with gemcitabine. Gemcitabine and nab-paclitaxel will be given intravenously, once a week for 3 out of 4 weeks, for a 28-day cycle. The goals of this study are: * To find the highest dose of nab-paclitaxel that can be safely given in combination with gemcitabine without causing severe side effects * To learn what kind of side effects nab-paclitaxel given in combination with gemcitabine can cause * To learn more about the pharmacology (how the body handles the drug) of nab-paclitaxel given in combination with gemcitabine * To evaluate tumor tissue for levels of certain proteins that may help with predicting who will benefit most from treatment with nab-paclitaxel * To determine whether nab-paclitaxel given in combination with gemcitabine is a beneficial treatment for relapsed and/or refractory solid tumors

Who can join

Age: 1 and older, up to 30. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Subjects must be ≥ than 6 months and ≤ 30 years of age at the time of study enrollment.
• Subjects must have had histologic verification of a malignancy at original diagnosis or relapse.
• All subjects with relapsed or refractory solid tumors are eligible, excluding primary CNS tumors.
• Patients with solid tumors and a history of intraparenchymal CNS disease are eligible if their CNS disease was treated surgically or with radiotherapy and stable with no recurrent lesions for at least 3 months from the start of protocol therapy.
• Newly diagnosed patients with ≤15% chance of cure if given standard-of-care chemotherapy are eligible. (Prognosis to be determined at the discretion of the treating physician.)
• Subjects must have either measurable or evaluable disease.
• Karnofsky ≥ 60 for subjects > 16 years of age and Lansky ≥ 50 for subjects ≤ 16 years of age. Subjects who are unable to walk because of paralysis, but who are up in a wheelchair, will be considered ambulatory for the purpose of assessing the performance score.
• Subjects must have fully recovered from the acute toxic effects of all prior anti-cancer chemotherapy.
• At least 21 days after the last dose of myelosuppressive chemotherapy (42 days if prior nitrosourea).
• At least 14 days after the last dose of a long-acting growth factor (e.g. Pegfilgrastim) or 7 days for short acting growth factor. For agents that have known adverse events occurring beyond 7 days after administration, this period must be extended beyond the time during which adverse events are known to occur. The duration of this interval must be discussed with the study chair.
• At least 7 days after the last dose of a biologic agent. For agents that have known adverse events occurring beyond 7 days after administration, this period must be extended beyond the time during which adverse events are known to occur. The duration of this interval must be discussed with the study chair.
• ≥ 42 days must have elapsed from last dose of any type of cellular therapy (e.g. modified T cells, natural killer (NK) cells, dendritic cells, etc.)
• ≥ 21 days must have elapsed from the last dose of interleukins, interferon or cytokines (other than Hematopoietic Growth Factors).
• ≥ 21 days must have elapsed from infusion of last dose of antibody, and toxicity related to prior antibody therapy must be recovered to Grade ≤ 1.
• At least 14 days after local palliative radiation therapy (XRT) (small port); 6 weeks must have elapsed since treatment with therapeutic doses of iodine-131 metaiodobenzylguanidine (131I-MIBG); At least 42 days must have elapsed if other substantial bone marrow (BM) radiation.
• No evidence of active graft vs. host disease and at least 84 days must have elapsed after transplant and 42 days for autologous stem cell infusion after 131I-MIBG therapy.
• Patients who have previously received a taxane, including nab-paclitaxel, or a nucleoside analogue, including gemcitabine, are eligible as long as they have not received gemcitabine in combination with nab-paclitaxel.
• ≥72 hours must have elapsed since the last administration of medical cannabis and cannabidiol (CBD Oil).
• ≥30 days must have elapsed since the last dose of any agents not specified above. For agents with an uncertain washout period or for any questions or uncertainty the study PI should be notified.
• Adequate bone marrow function defined as:
• For subjects with solid tumors without known bone marrow involvement: Peripheral absolute neutrophil count (ANC) ≥ 750/mm3. Platelet count ≥ 75,000/mm3 (transfusion independent, defined as not receiving platelet transfusions for at least 7 days prior to enrollment)
• Subjects with known bone marrow metastatic disease will be eligible for study provided they meet the blood counts of peripheral absolute neutrophil count (ANC) ≥ 750/mm3 and platelet count ≥ 75,000/mm3 (may receive transfusions provided they are not known to be refractory to red cell or platelet transfusions). These subjects will not be evaluable for hematologic toxicity. At least 5 of every cohort of 6 patients must be evaluable for hematologic toxicity for the dose-escalation part of the study. If dose-limiting hematologic toxicity is observed, all subsequent subjects enrolled must be evaluable for hematologic toxicity.
• Adequate renal function defined as:
• Creatinine clearance or radioisotope glomerular filtration rate (GFR) 70ml/min/1.73 m\^2 or
• A serum creatinine based on age/gender using threshold creatinine values derived from the Schwartz formula for estimating GFR utilizing child length and stature data published by the Centers for Disease Control and Prevention (CDC).

You may not qualify if…

• Female patients who are pregnant are ineligible for study. Lactating females are not eligible unless they have agreed not to breastfeed their infants from the time of informed consent through the duration and at least 1 month following the last dose of investigational agent. Female patients of childbearing potential are not eligible unless a negative pregnancy test result has been obtained. Sexually active patients of reproductive potential are not eligible unless they have agreed to use an effective contraceptive method from the time of informed consent through the duration and for 1 month following the last dose of investigational agent. The definition of an effective contraceptive method will be at the discretion of the institutional investigator.
• Patients taking any the following concomitant medications are not eligible:
• Subjects who are currently receiving another investigational drug.
• Subjects who are currently receiving other anti-cancer agents.
• Subjects who are receiving cyclosporine, tacrolimus, or other agents to prevent graft-versus-host disease post bone marrow transplant.
• Subjects using medications which interfere with CYP3A4 and CYP2C8 metabolism, which metabolize nab-paclitaxel. Paclitaxel is metabolized by CYP3A4 and CYP2C8, so strong inhibitors or inducers of these enzymes should be avoided.
• Patients with any of the following adverse events at the time of enrollment are not eligible:
• Grade ≥ 2 Motor, sensory or peripheral neuropathy. This does not apply to patients with neuropathic symptoms related to tumor or prior therapy, i.e. surgery or radiation. Patients with mild neuropathy well controlled with medications are eligible.
• Grade ≥3 Hyponatremia (serum Na ≤ 130 mmol/L)
• Subjects who have an uncontrolled infection are not eligible.
• Subjects who have received prior solid organ transplantation are not eligible.
• Subjects who in the opinion of the investigator may not be able to comply with the safety monitoring requirements of the study are not eligible.
