Skin is considered the most accessible organ of the body because of its underlying capillary network. However, stratum corneum (SC), the upper most layer of skin, represents major diffusional barrier for most drugs. Hence, the use of edge activators (EAs) in designing novel elastic vesicles is hypothesized to impart their lipid bilayer with ultra-flexibility to trespass SC by high self-optimizing deformability.

Liposome supported peritoneal dialysis is a recently described technique which may eventually be applicable in the clinical scenario of the intoxicated patient. We evaluated the hypothesis that intravenous injection of lipid emulsion (ILE) would augment acidic pH gradient liposome supported peritoneal dialysis (LSPD). Orogastrically amitriptyline dosed rats were treated with either Sodium bicarbonate (NaHCO3) intravenously and standard intraperitoneal dialysate (Group A); NaHCO3 intravenously and LSPD (Group B); or ILE and LSPD (Group C).

Microfluidic preparation of drug-loaded PEGylated liposomes, and the impact of liposome size on tumour retention and penetration.

J Liposome Res 2019 Mar 20;29(1):1-9. Epub 2017 Nov 20.

a Drug Delivery Disposition and Dynamics , Monash Institute of Pharmaceutical Sciences, Monash University , Melbourne , Australia.

Understanding the effect of liposome size on tendency for accumulation in tumour tissue requires preparation of defined populations of different sized particles. However, controlling the size distributions without changing the lipid composition is difficult, and differences in compositions itself modify distribution behaviour. Here, a commercial microfluidic format as well as traditional methods was used to prepare doxorubicin-loaded liposomes of different size distributions but with the same lipid composition, and drug retention, biodistribution and localization in tumour tissues were evaluated.

a Gilead Sciences Inc. , San Dimas , CA , USA.

AmBisome (liposomal amphotericin B) is among the earliest approved liposomal therapeutics, and has been in commercial use since the early 1990s. This review provides examples of non-clinical, regulatory, clinical label expansion, adverse event management, and supply chain control reflecting the real world challenges of a commercial liposomal therapeutic. We review examples of post-approval clinical development in severe lung infections, development of US and European guidance documents around liposomal therapeutics, the creation of a suitable placebo for blinded clinical trials, response to findings of a possible new category of adverse event (what turned out to be pseudohyperphosphatemia), challenges in handling the finished product in a setting with high risk of exposure of the product to temperatures outside of the established label storage conditions, and elements of continuingly increased aseptic processing requirements for manufacturing.

In vitro evaluation of archaeosome vehicles for transdermal vaccine delivery.

J Liposome Res 2018 Dec 26;28(4):305-314. Epub 2017 Sep 26.

a Department of Human Health Therapeutics , National Research Council Canada , Ottawa , Canada.

Archaeosomes composed of archaeal total polar lipids (TPL) or semi-synthetic analog vesicles have been used as vaccine adjuvants and delivery systems in animal models for many years. Typically administered by intramuscular or subcutaneous injections, archaeosomes can induce robust, long-lasting humoral and cell-mediated immune responses against entrapped antigens and provide protection in murine models of infectious disease and cancer. Herein, we evaluated various archaeosomes for transdermal delivery, since this route may help eliminate needle-stick injuries and needle re-use, and therefore increase patient compliance. Read More

Monomeric M2e antigen in VesiVax liposomes stimulates protection against type a strains of influenza comparable to liposomes with multimeric forms of M2e.

J Liposome Res 2017 Sep 5;27(3):210-220. Epub 2017 Oct 5.

b Molecular Express Inc , Rancho Dominguez , CA , USA.

Given the interest in the ectodomain of the matrix 2 (M2e) channel protein as a target for development of a universal influenza vaccine, we examined the role of the antigen configuration of M2e in generating a protective immune response. A series of M2e mutations and a truncated M2e segment were prepared as a means of controlling the formation of monomer, dimer, and higher order multimeric forms of M2e. Each of these M2e peptides was incorporated into a liposome-based vaccine technology platform previously shown to stimulate a protective response to influenza A infection using M2e as a mixture of monomers, dimers and multimers (L-M2e1-HD/MPL).

Drugs used for the treatment and prevention of malaria are often plagued by the problem of development of resistance. This has hampered their therapeutic efficiency and rendered them ineffective for monotherapy. However, if re-packaged and combined properly, many of these neglected anti-malarial drugs can possibly find their way back into the treatment regime. Read More
