Filter by:Febrile neutropenia (FN) is a clinically important adverse effect of myelosuppressive chemotherapy. If patients present with FN, attention is focussed on well-recognized sites of origin of infection: the airways, urinary tracts, and skin. However, infections can be only documented clinically in about two-third of febrile episodes, whereas a causative microbial pathogen cannot be identified in the majority (>70%) of cases. Pre-treatment oral evaluation aimed to identify and eliminate oral/dental foci is only routinely used in patients at high risk for oral complications (i.e. head and neck cancer patients and stem cell transplantation recipients). However, any patient treated with myelosuppressive chemotherapy, be it for cure or palliation, is at risk of developing infection in and/or originating from the oral cavity. Nevertheless, in these patients dental screening is somewhat randomly employed at the oncologist's discretion. More insight into the pre-treatment oral condition and its potential role in FN is mandatory, particularly considering the growing numbers of older patients retaining their natural dentition and the increase of dental diseases and cancer incidence with age. In addition, oral diseases may aggravate chemotherapy-induced oral mucositis (OM). OM is associated with an inflammatory response, which together with ulcerations providing a portal of entry for bacteria, can result in FN and systemic inflammatory syndrome (SIRS) and/or sepsis. Evidence suggests that microorganisms are involved in the pathobiology of OM, but no longitudinal studies using open-end sequencing are available. Furthermore, comparing bacteria identified in blood cultures in febrile patients with those of the oral cavity will expand the knowledge on the role of the oral cavity as a potential source of bacteremia. The investigators expect that the results will provide a scientific base for subsequent intervention studies on the efficacy of dental screening and elimination of foci, and other interventions aimed at modifying the oral environment before and during chemotherapy.
A Randomized, Open-Label, Single -Dose, Crossover, Phase I Clinical Trial to Evaluate the Effect of Food on the Safety, Tolerability and Pharmacokinetics of EC-18 after Oral Administration in Healthy Volunteers
Neutropenia is the most serious hematologic toxicity of cancer chemotherapy, often limiting the doses and density of chemotherapy that can be tolerated. The degree and duration of neutropenia determine the risk of infection. Myelo001, a small orally bioavailable molecule, has been shown in chemotherapy- or radiotherapy-induced myelosuppression to stimulate differentiation of peripheral white blood cells (WBC) and bone marrow cells of the leucocytic, lymphocytic, and erythrocytic lineage. The purpose of the MyeloConcept study is to determine the safety and effectiveness of Myelo001 in preventing or reducing chemotherapy-induced neutropenia and myelosuppression in patients receiving chemotherapy due to breast cancer.
To compare the efficacy and safety of Day 2 (D2) once a cycle pegfilgrastim with Intermittent Every Other Days of 5 Shot (D3-11) filgrastim in early breast cancer patients treated with adjuvant Docetaxel, Doxorubicin, and Cyclophosphamide (TAC) regimen
Folic acid (FA; folate) in the dose of 350-1,000 μg daily should be supplemented, daily, starting 7 days before the first dose of pemetrexed based chemotherapy and should be continued while the patient is on therapy and for 21 days after cessation of therapy. Vitamin B12 injections (1,000 μg i.m.) should also be started 1 week before the first dose of chemotherapy. However, the evidence for delaying chemotherapy by seven days for the purpose of giving vitamin B12 and FA supplementation is not robust. Observational and prospective single arm studies have not shown any increased toxicity if pemetrexed was started earlier than the recommended duration of supplementation. In a resource constrained setting, this will lead to one additional visit and 1-week chemotherapy delay which may be inconvenient for patients. Hence an open label, randomized control trial is being undertaken to evaluate if there are any differences in pemetrexed related hematological toxicity amongst patients who receive delayed initiation of chemotherapy (following 5 - 7 days of vitamin B12 and FA supplementation; Delayed Arm) as compared to those in whom vitamin B12 and FA supplementation is starting simultaneously (within 24 hours) of initiation of chemotherapy (Immediate Arm).
This study is designed to access the tolerability and Pharmacokinetic/Pharmacodynamic (PK/PD) of single subcutaneous (SC) injection of GW003 in healthy subjects.
The purpose of this study was to compare the efficacy of a single dose of SPI-2012 versus pegfilgrastim in participants with early-stage breast cancer receiving docetaxel and cyclophosphamide (TC), as measured by the duration of severe neutropenia (DSN) in Cycle 1.
This study is for healthy participants. This study tests single dose of the research drug HSP-130 against two existing approved drugs United States - approved Neulasta and European Union-approved Neulasta.
The pharmacokinetics of Sporanox and Lozanoc has not been compared in patients requiring anti-fungal prophylaxis or therapy. The present study is designed to compare the pharmacokinetics of Sporanox and Lozanoc in patients requiring primary prophylaxis. The 3-week exposure to each formulation is designed to allow for all participants to reach steady-state for each drug, as the time to steady-state can vary.
This study will evaluate the pharmacokinetics (relative bioavailability) and pharmacodynamics, after single subcutaneous application, in healthy volunteers of both sexes, between pegfilgrastim formulation, produced by Eurofarma Laboratorios S/A and Neulastim® (reference formulation), marketed by Produtos Roche Químicos e Farmacêuticos S/A. In addition to that, a pharmacodynamics comparison will be performed, through change in absolute neutrophil count in leukogram performed in the same time of pharmacokinetics analysis collection and through CD34+ cell count in peripheral blood at timepoints 0:00, 96:00 and 384:00 hours.
