英文摘要
Project Summary
It is estimated that up to 90% of emerging drug candidates have significantly less than optimal aqueous
solubility, which will impede their efficient delivery to the body. Amorphous solid dispersions (ASDs) have
emerged as an important approach to improve oral bioavailability of low solubility drugs. However, the
interplay of manufacturing conditions, polymer choice, and storage conditions on the critical quality attributes
of ASDs that impact dissolution, precipitation and ultimately in vivo performance is poorly understood. There
is also concern within the medical community that generic ASD products may not perform as well as brand
products. The objective of the current proposal is to evaluate the impact of formulation components,
processing parameters and storage conditions on the in vitro and in vivo performance of ASDs of relevant
poorly water soluble drugs. The rationale for this research is that its successful completion will enable an
understanding of processing and formulation factors that impact the robustness of brand and generic ASD
formulations, insuring product quality. The specific aims are to:
1) Demonstrate that drug‐polymer miscibility depends both on drug and polymer chemistry and on
processing conditions, comparing ASDs prepared with spray drying and melt extrusion.
2) Using innovative analytical approaches, show that differences in product performance for ASDs
prepared with spray drying versus hot melt extrusion depend on critical quality attributes that include,
drug‐polymer homogeneity, residual crystallinity and dissolution performance. Determine critical
process parameters specific to each manufacturing technique that impact these critical quality
attributes. Demonstrate that precipitation behavior can be modified by formulation components and
that precipitation to a non‐crystalline form has very different consequences for product performance
compared to crystallization.
3) Compare and contrast the quality attributes of brand and generic ASD products in terms of assay,
related substances, dissolution performance and other critical quality attributes.
4) Compare and contrast brand and generic ASD formulations in terms of the robustness of the
formulation to stressed storage conditions. Performance attributes that will be assessed include
evolution of crystallinity with time as a function of moisture content, as well as dissolution rate and
precipitation tendency/outcome at different time points.
5) Conduct a clinical trial to evaluate the in vivo performance of fresh and aged brand and generic ASD
preparations.
