This is a phase 2 study looking at efficacy and toxicity of oral sirolimus in combination with oral methotrexate in children with refractory/relapsed ALL or NHL. Secondary objectives include characterizing the trough levels produced by administration of oral sirolimus in children with refractory/relapsed ALL/NHL and to evaluate the effect of sirolimus on intracellular targets related to mTOR inhibition.
It will be conducted as an international multicenter prospective observational cohort study in a population of ErbB2 positive metastatic breast cancer patients, whose disease has progressed after trastuzumab-containing regimen, comparing outcomes in two groups: Group 1: patients receiving Lapatinib-capecitabine immediately after 1st Trastuzumab progression (second line treatment), and Group 2: patients receiving Lapatinib-capecitabine after 2 or more lines of treatment after 1st trastuzumab progression (third line or greater).
This study will evaluate the relative bioavailability of 2 oral formulations of TKI258, and the effect of food on the bioavailability of TKI258, in adult patients with advanced solid tumor.
This study is being done to examine the effect of Parenteral (intravenous) nutrition support in the home setting on quality of life in cancer patients. In addition, this study is being done to examine the effect of home parenteral nutrition on the use of pain and anti-nausea medication.
Despite the known adverse effects of specific cancer treatments on fertility, only 18-26% of at-risk adolescents and young men cryopreserve sperm prior to cancer treatment in the US: These already less than optimal rates of sperm banking are even lower among adolescents who have increased anxiety at cancer diagnosis, are lower in age and socioeconomic status, of Evangelical religious orientation, or are diagnosed with leukemia/lymphoma: It is not clear why sperm banking is underutilized, particularly in light of the high priority that survivors of childhood cancer place on fertility and the high psychological distress associated with fertility loss. Studies addressing sperm banking among adults with cancer suggest that factors such as poor physician communication and the resulting lack of fertility-risk knowledge by patients contributes to the low frequency of sperm cryopreservation. No well-designed studies have examined risk factors associated with failure to bank sperm among adolescents with cancer, a developmentally distinct population ripe for intervention. This study plans to enroll 206 adolescent males and 412 parents/guardians.
The study consists of two parts: Drug Interaction (Pharmacokinetic) Phase and Pharmacodynamic Phase The primary study objective for the Drug Interaction Study is to determine the pharmacokinetic interactions between RAD001 and JI-101. The primary study objective for the Pharmacodynamic Study is progression-free survival at 2 moths, evaluated separately in each of the three cohorts. These will include a determination of tumor response using Response Evaluation Criteria in Solid Tumors (RECIST) Criteria and an assessment of ephrinB4 expression in blood samples. Secondary objectives are to determine safety and tolerability of JI-101. The investigational products are everolimus (42-O-(2-hydroxyethyl) rapamycin) and JI-101 (1-[1-(2-amino-pyridin-4-ylmethyl)-1H-indol-4-yl]-3-(5-bromo-2 methoxy-phenyl)-urea) Eligible patients meeting all study entry criteria will be enrolled in the study. For the Drug Interaction study, patients with solid tumors will receive a single dose (10 mg) of Everolimus by mouth on Day 1 and Day 8 and JI-101 capsules (200 mg) by mouth on Day 8 and Day 15. For the Pharmacodynamic Study, all patients will receive JI-101 capsules by mouth (200 mg BID) for 28 day treatment cycles.
Blood samples on persons with cancer will be sampled for angiogenic, metastatic and coagulation proteins.
Background: - Research has shown that certain proteins in cells may be linked to higher risks of developing inflammations, tumors, and other medical problems. By examining how the blood cells of healthy volunteers respond to environmental exposures, researchers hope to better understand the relationship of genes, environmental factors, and human diseases. Objectives: - To examine how specific genes and proteins in blood cells respond to environmental exposures. Eligibility: - Healthy volunteers between 18 and 45 years of age. Design: - The study will involve one visit of 45 to 60 minutes. - Participants will be screened with a brief physical examination and finger stick to determine if they are eligible to donate blood for the study, and will complete a questionnaire about any medications or other drugs (e.g., cigarettes) they may be taking. - Participants will provide a blood sample for research purposes.
Background: - Innate immunity is the process by which white blood cells and other parts of the immune system sense and respond to potential infections by causing an inflammation. Researchers are interested in studying how the body responds to certain environmental factors, and whether the body s response can contribute to chronic illnesses or diseases such as asthma and certain types of cancers.
