Filter by:In patients with early-stage breast cancer, chemotherapy has substantially improved survival rates for breast cancer patients. Improvements in outcomes, however, are compromised by the considerable toxicities associated with chemotherapy, most notable being neutropenia. Neutropenia is the presence of abnormally few white blood cells, leading to increased susceptibility to infection and can require hospitalization and need for intravenous antibiotics and is sometimes fatal. Febrile neutropenia can also be associated with treatment delays and dose reductions, potentially compromising treatment efficacy. Patients can receive medication to reduce the risk of febrile neutropenia, such as Neupogen (Filgrastim) as a daily injection for 5, 7, or 10 days. Since there is genuine uncertainty amongst healthcare professionals as to which administration schedule of Neupogen is better, investigators are performing a randomized study in which patients are put into a group by chance to give participants one of three standards of Neupogen daily injection. Neupogen can cost approximately $200 per injection, so if a physician prescribes 10 days for 8 cycles of treatment this can cost $16,000 compared to a 5 day prescription which would cost half this. In addition to cost savings, many patients are not able to give themselves injections on a daily basis and require nursing resources which are utilized at high-cost. This study will use an "integrated consent model" that involves an "oral consent" rather than a written informed consenting process in order to increase the number of patients who may participate while performing a study at a lower cost. While determining the optimal treatment will improve patient comfort and acceptability, using the minimal safe duration of administration may also offer cost savings.
Clinical triple-blind randomized controlled trial to assess the use of two different mouthwashes to reduce the oral colonization by gramnegative bacteria in patients with chemotherapy
Clozapine (CLZ) is the most effective antipsychotic for treatment-refractory schizophrenia (SZ). Despite the overwhelming evidence of superior efficacy, CLZ is infrequently prescribed in the US, at a considerably lower rate than the estimated prevalence of treatment-resistant SZ, especially for African-Americans (AA). Recent evidence suggests that low Absolute Neutrophil Counts (ANC), either at baseline or during treatment are a significant barrier to CLZ use in AA patients in the US, where guidelines mandate CLZ discontinuation if ANC drops below 1500 cells/mm3. The investigators group has found that discontinuation of CLZ in AA patients is over twice that in European-American (EA) patients (N~400; 42% vs.19%, P=0.041) and initiation rates are 50% lower. In a Statewide study (N=1875), the investigators reported that discontinuation was more frequently due to neutropenia in the AA sample, though no AA had developed agranulocytosis (8 cases in EA). Benign Ethnic Neutropenia (BEN) in people of African ancestry, including AAs, identifies a group (50% of AA) with low ANCs but no increased risk of agranulocytosis or infection. Low baseline or in-treatment fluctuations requiring CLZ discontinuation under current prescribing guidelines are common in CLZ-treated persons with BEN. In the investigators recent pilot study of N=12 AA patients with BEN, treatment was safely and successfully continued with CLZ despite low baseline ANC (outside current guidelines). Recent evidence implicates a polymorphism in the Duffy Antigen Receptor Chemokine (DARC) gene in the pathophysiology of BEN. In homozygotes (FY-/-) for the DARC null allele, mean within-subject neutrophil counts are reduced, resulting in sporadic ANC <1500 cells/mm3 in 10-15% of people with the allele. In population studies, the FY-/- genotype is found in 0.01% of EAs, 99.3% of sub-Saharan Africans (SSA), and 68% of AAs. Further, a missense DARC mutation has been reported to interact with the DARC FY-/- in determining low WBC in AAs. Normal patterns of week-to-week fluctuation in ANC levels in individuals of African ancestry with BEN and the DARC null genotype are not known, and no published research has examined variation in ANC in African ancestry CLZ-treated SZ patients with BEN and the DARC null genotype (FY-/-). Such data are also lacking on individuals with BEN without the DARC null genotype. Conducting such research will generate genetic marker and safety data that could be used to expand access to CLZ for AA patients who otherwise are eligible to receive this superior treatment option.
In a multi-center open-label cluster-randomized controlled parallel-group multiple crossover non-inferiority trial in children and adolescents up to 20 years diagnosed with cancer requiring chemotherapy, primarily the safety, and secondarily the efficacy and other endpoints, of a high (39.0°C) versus low (38.5°C) temperature limit defining fever (TLDF) for the diagnosis of fever in chemotherapy-induced neutropenia (FN) is studied. Safety is assessed by the rate of safety relevant events per chemotherapy exposure time, a composite endpoint including serious medical complications and bacteremia during FN. Patients are repeatedly randomized (cluster: study site) to the high or the low TLDF every month, resulting in possible multiple crossovers in one patient. The high TLDF is declared not to be inferior regarding safety compared to the low TLDF if non-inferiority of the rate ratio of safety relevant events is proven, with a single-sided non-inferiority margin of 1.33, applying mixed Poisson regression.
The purpose of the study is to explore the safety and efficacy of CLT-008 as an extra supportive care measure after induction chemotherapy for patients with acute myeloid leukemia (AML).
Febrile neutropenia (FN) is a common and serious side effect of chemotherapy. Current management of FN is expensive and may induce side effects. Honey is a natural substance produced by honeybees. It possesses antioxidant, antimicrobial and anticancer effects. In addition, honey is not expensive. The aim of this study was to evaluate the effects of 12-week honey consumption on children with acute lymphoblastic leukemia (ALL) particularly with regards of FN episodes. This randomized crossover clinical trial included 40 patients of both sexes, aged 2.5 to 10 years. They were randomized into two equal groups [intervention to control (I/C) and control to intervention (C/I)]. The dietary intervention was 12-week honey consumption in a dose of 2.5g//kg body weight per dose twice weekly.
The primary objective of this study is to assess the efficacy of monosialotetrahexosylganglioside (GM1) for preventing oxaliplatin induced neurotoxicity in colorectal cancer patients who received oxaliplatin-based adjuvant chemotherapy.
Background: - WHIMS (Warts, Hypogammaglobulinemia, Infections, and Myelokathexis Syndrome) is a rare disease. It can cause cancers, infections, and warts. Researchers want to see if a drug called plerixafor can treat WHIMS. Objective: - To compare plerixafor versus granulocyte colony stimulating factor (G-CSF) for preventing infections in people with WHIMS. Eligibility: - People ages 10-75 with WHIMS who have a CXCR4 gene mutation. Design: - Participants will be screened with a medical history, physical exam, and blood and urine tests. They may have heart and spleen tests and body scans. They may have samples of skin or warts taken. Researchers may take photographs of warts. - Participants will start twice daily self-injections of G-CSF. Their doctors will decide the dosage. - Initial Period (4-12 weeks) - Participants will: - continue the injections and their usual antibiotics and/or immunoglobulin - have blood drawn - keep a daily health diary - Participants will visit the clinic for 2 days without injections. - Adjustment Period 1 (8 weeks): - Participants will: - continue twice daily injections from home - continue the daily health diary - have blood tests every 2 weeks. - Treatment Year 1: - Participants will - receive either plerixafor or G-CSF injections twice daily - continue the health diary - have blood tests every 2 months - visit the clinic about every 4 months - At the end of year 1, participants will visit the clinic for an evaluation. They will switch to the other study drug. They will have an 8-week adjustment and 1-year treatment period. - At the end of year 2, participants will visit the clinic to complete their injections and go back to their previous G-CSF regimen. Participants will continue their daily health diary and have blood tests for 5-6 months.
This is prospective and randomized study to compare the pharmacodynamics (t>MIC) of 0.5 g every 6 h of imipenem in twelve patients with febrile neutropenia following administration by a 4 h infusion or bolus injection. Concentration of imipenem in plasma will be measured by HPLC method and simulated in Monte Carlo technique (Computer model) to get PK/PD index (40%T>MIC) and reported to %PTA (Probability Target Attainment) and %CFR (Cumulative Faction Response.
The purpose of the study is to evaluate the safety, pharmacokinetics, pharmacodynamics, and efficacy of daily subcutaneous administration of 5 μg/kg tbo-filgrastim in infants, children and adolescents with solid tumors without bone marrow involvement.
