Nanomedicine drug products have reached an unprecedented high in terms of global commercial acceptance and media exposure with the approvals of the mRNA COVID-19 vaccines in 2021. In this paper, we examine the current state of the art for nanomedicine technologies as applied for pharmaceutical products and compare those trends with results from a recent IQ Consortium industry survey on nanomedicine drug products. We find that 1) industry companies continue to push the envelope in terms of new technologies for characterizing their specific drug products, 2) new analytical technologies continue to be utilized by industry to characterize the increasingly complex nanomedicine drug products and 3) alignment and communication are key between industry and regulatory authorities to better understand the regulatory filings that are being submitted. There are many CMC challenges that a company must overcome to successfully file a nanomedicine drug product. In 2022, the FDA Guidance on Drug Products containing Nanomaterials was published, and it provides a roadmap for submission of a nanomedicine drug product. We propose that our paper serves as a complimentary guide providing knowledge on specific CMC issues such as quality attributes, physicochemical characterization methods, excipients, and stability.

Background: Impaired Aβ clearance plays a key role in the common, late-onset AD. Anti-Aβ immunotherapies are controversial, in part because of high rates of serious side effects including edema, microhemorrhages, and siderosis, highlighting the importance of the development of alternative Aβ clearance strategy. Here, we introduce a bioinspired nanoparticle named MG-PE3 crossing the human blood-brain barrier (BBB) and clearing Aβ with no adverse effect.

Background: Cognitive decline associated with Alzheimer's disease (AD) correlates with hyperphosphorylated tau (pTau) propagating between neurons along networks connected by synapses. It has been hypothesized this transcellular transmission occurs partially by extracellular vesicles (EVs). Both genetic and pharmacological inhibition of nSMase2 has been found to inhibit EV biogenesis and pTau propagation.

Background: The 3D printing of macro- and mesoporous biomimetic grafts composed of polycaprolactone (PCL) infused with nanosized synthetic smectic clay is a promising innovation in biomaterials for bone tissue engineering (BTE). The main challenge lies in achieving a uniform distribution of nanoceramics across low to high concentrations within the polymer matrix while preserving mechanical properties and biological performance essential for successful osseointegration.
Methods: This study utilized 3D printing to fabricate PCL scaffolds enriched with nanosized synthetic smectic clay (LAP) to evaluate its effects on structural, chemical, thermal, mechanical, and degradative properties, with a focus on in vitro biological performance and non-toxicity.

Thiol-maleimide (MI) chemistry is a cornerstone of bioconjugation strategies, particularly in the development of drug delivery systems. The cyclic arginine-glycine-aspartic acid (cRGD) peptide, recognized for its ability to target the integrin αβ, is commonly employed to functionalize maleimide-bearing nanoparticles (NPs) for fabricating cRGD-functionalized nanomedicines. However, the impact of cRGD density on tumor targeting efficiency remains poorly understood.
