Encapsulation of a CpG oligonucleotide in cationic liposomes enhances its local antitumor activity following pulmonary delivery in a murine model of metastatic lung cancer.

Immunotherapy brings new hope to the fight against lung cancer. General immunostimulatory agents represent an immunotherapy strategy that has demonstrated efficacy with limited toxicity when delivered intratumorally. The goal of this study was to enhance the antitumor efficacy of unmethylated oligodeoxynucleotides containing CpG motifs (CpG) and polyinosinic-polycytidylic acid (poly I:C) double-stranded RNA following their local delivery in lung cancer by encapsulating them in liposomes.

Temozolomide-loaded photopolymerizable PEG-DMA-based hydrogel for the treatment of glioblastoma.

Glioblastoma is the most frequent primary malignant brain tumor in adults. Despite treatments including surgery, radiotherapy and chemotherapy by oral Temozolomide (TMZ), the prognosis of patients with glioblastoma remains very poor. We hypothesized that a polyethylene glycol dimethacrylate (PEG-DMA) injectable hydrogel would provide a sustained and local delivery of TMZ.

Vitamin E-based micelles enhance the anticancer activity of doxorubicin.

The purpose of this study was to develop vitamin E-based micelles loaded with Doxorubicin (DOX) (DOX-TOS-TPGS), taking advantages of the anti-cancer activity of vitamin E derivatives: Tocopherol succinate (TOS) and D-α-tocopherol polyethylene2000 succinate (TPGS). Therefore, we developed micelles consisting in a mixture of TOS (as solubilizer) and TPGS2000 (as stabilizer) (1:1). DOX-TOS-TPGS micelles exhibited a size of 78 nm and a ζ potential of -7 mV.
