CTZ was spray dried using three different atomising gas flowrate settings to determine whether it has any effect on the solid-state of CTZ. At a lower atomising gas flowrate, a new form of CTZ, CTZ form IV, was obtained in pure form, whereas at the highest atomising gas flowrate, a mixture of CTZ form I and CTZ form IV was obtained. The morphology of CTZ form I was prism-shaped, and the new form, CTZ form IV, consisted of spherical clusters, some of which were porous and some non-porous. As a result of the rapid drying process, acetone was trapped within the porous clusters and could be released by milling. CTZ form IV has been shown to be stable at room temperature and below 40% relative humidity (RH); however, after 1 week of stability under accelerated conditions of 40 °C/75% RH, CTZ form IV converted to CTZ form I. Also, at high temperatures between 150 °C and 175 °C, CTZ form IV converted to form I, with the simultaneous release of acetone upon its morphology change.

In contrast, viral infections efficiently trigger innate and adaptive immunity. This is attributed to the high immunogenicity of microbial antigens and also to the activation of pattern recognition receptors such as retinoic acid-inducible gene-I (RIG-I). Upon recognizing viral RNA, RIG-I induces secretion of type-I interferons (IFNs). Type I IFNs not only invite antiviral effects but also plays an effective role in cancer immunotherapy. Therefore, activation of RIG-I by the ligands has gained attention as a novel cancer immunotherapy in recent years. Virus-associated RNAs (VA-RNA I and VA-RNA II) are non-coding small RNAs generated from the adenovirus genome. VA-RNA I strongly activates RIG-I, leading to type-I IFN production. In this study, plasmid DNAs encoding both VA-RNA I and II [pDNA(I,II)] or only VA-RNA I [pDNA(I)] were prepared, and their IFN inducing and anti-tumor effects were investigated. In culture cells, introduction of pDNA(I,II) or pDNA(I) effectively induced both IFN-α and IFN-β production. Both plasmids significantly inhibited tumor growth in mice. pDNA(I) exhibited superior IFN-inducing and anti-tumor effects compared to pDNA(I,II).

High-concentration formulations of antibodies are needed to meet the limited-volume requirements of subcutaneous SC delivery. Despite this need, there remain challenges in delivering stable and injectable antibodies in these high concentrations. Hydrogel encapsulation of amorphous solid antibodies has been proven to improve the stability and injectability of high-concentration antibody formulations. However, the antibody is quickly released from the hydrogel due to the material's porosity, leading to rapid, uncontrolled drug release kinetics undesirable for the drug's efficacy and safety. In this paper, we propose a dual-network composite hydrogel which leverages interactions between the two polymer networks to achieve controlled release of the antibody. We load the solid form of the antibody at high concentrations within alginate hydrogel microparticles which are then suspended in thermogelling methylcellulose solution to formulate the <em>in situ</em> gelling composite hydrogel. By facile chemical modification of the alginate to tune the microparticles’ gel properties and alginate–methylcellulose interactions, we demonstrate how the composite system can delay release of the drug in a tunable manner and achieve a near-zero order release profile for improved therapeutic efficacy. We show acceptable injectability properties of the composite hydrogel at high antibody concentrations, highlighting the functionalities of dualnetwork encapsulation.

This study was designed to develop novel solid self-nanoemulsifying drug delivery systems (S-SNEDDS) for cyclosporine (CYC), using chitosan–EDTA microparticles. Such microparticles are known to exhibit superior adsorbent characteristics and were prepared by two different methods <em>viz</em>. spray drying (SD-CHEM) and solvent evaporation (SE-CHEM). Capmul® GMS-50K, Labrafac, and PEG 400 were chosen as the oil, surfactant, and co-surfactant, respectively.

The novel S-SNEDDS were developed by adsorbing CYC-L-SNEDDS onto the chitosan–EDTA microparticles, resulting in CYC-SD-S-SNEDDS and CYC-SE-S-SNEDDS. Both formulations exhibited favorable drug loading, with 81.184 ± 4.191% for CYC-SD-S-SNEDDS and 56.426 ± 5.471% for CYC-SE-S-SNEDDS.
