AbstractGene therapy is a therapeutic approach to deliver genetic material into cells to alter their function in entire organism. One promising form of gene delivery system (DDS) is liposomes. The success of liposome-mediated gene delivery is a multifactorial issue and well-designed liposomal systems might lead to optimized gene transfection particularly in vivo. Liposomal gene delivery systems...

Prolonged exposure to vincristine correlates with improved therapeutic activity. In this work, two methods are used to increase the circulation longevity of liposomal formulations of vincristine. The first involves incorporation of the ganglioside GM1, which acts to increase the circulation longevity of liposomal carriers, while the second approach relies on a modification of the vincristine en...

OBJECTIVE Farletuzumab is a humanized monoclonal antibody that binds to folate receptor alpha, over-expressed in epithelial ovarian cancer (EOC) but largely absent in normal tissue. Previously, carboplatin plus pegylated liposomal doxorubicin showed superior progression-free survival and an improved therapeutic index compared with carboplatin/paclitaxel in relapsed platinum-sensitive EOC. This ...

OBJECTIVE To evaluate the cost-effectiveness of caspofungin versus liposomal amphotericin B as empiric antifungal treatment in patients with neutropenic fever in Italy. METHODS The cost-effectiveness of caspofungin versus liposomal amphotericin B was evaluated using a decision-tree model. Patients were stratified by presence or absence of baseline infection. Model outcomes included success in...

Celecoxib, a selective cyclooxygenase-2 inhibitor, has shown potential anticancerous activity against majority of solid tumors especially on patients with colon cancer. However, associations of serious side effects limit the usage of celecoxib in colon cancer treatment. To address this issue and provide an alternative strategy to increase the efficacy of celecoxib, liposomal formulation of cele...

There is no standard systemic treatment for persons with recurrent meningioma who have exhausted surgery and radiation options. Liposomal doxorubicin is a cytotoxic chemotherapy which is sustainable and tolerable, with activity against a range of solid tumors. There exists one reported case of metastatic meningioma effectively treated with liposomal doxorubicin. We report a second case. Our pat...

Intestinal lymphatic drug delivery has been widely studied because drugs can bypass the first-pass metabolism in the liver via the lymphatic route, which increases oral bioavailability. Various lipid-based nanoparticles have been used to deliver hydrophobic drugs to the lymphatic pathway. This review focuses on the liposomal delivery systems used for intestinal lymphatic drug transport. Liposom...

We report the penetration of liposomal amphotericin B into the pleural fluid of a patient with pulmonary zygomycosis and empyema. The ratio of area under the concentration-versus-time curve in pleural fluid (AUC(pleural fluid)) to that in serum (AUC(serum)) for liposomal amphotericin B over 24 h was 9.4%, with pleural fluid concentrations of 2.12 to 4.91 microg/ml. Given the relatively low leve...

Tumor-specific targeting is a critical goal in the research area of liposomal drug delivery. Identification of the specific interactions between ligands and target tumor cells is a principle prerequisite in achieving this goal. Generally, tumor cells aberrantly express tumor-associated antigens that can be utilized as appropriate target molecules. Monoclonal antibodies against tumor-associated ...
