Quality Target Product
Profile (qTPP)

Tergus scientists will work with you to establish a qTPP. The target product profile identifies critical parameters that will impact product quality. This includes, but is not limited to, dosage form, target strength, aesthetics, and shelf-life.

Critical Process
Parameters (CPPs)

Manufacturing processes that should be within a specified range to ensure product quality. At Tergus, we take care to evaluate the manufacturing process from bench to large-scale as these parameters can significantly impact emulsion stability. Our manufacturing facility has 5 vessels that are directly scalable, thereby minimizing risk as your clinical needs change

Critical Quality
Attributes (CQAs)

Physical, chemical, or biological characteristics that can be defined and measured over time to confirm product quality. From evaluation of CMAs and CPPs during formulation development to manufacturing of clinical supplies and stability testing, Tergus is your one-stop shop for quality by design. Our teams understand the nuances of semi-solids and work with you to monitor CQAs and troubleshoot as needed.

Critical Material
Attributes (CMAs)

A physical, chemical, or biological characteristic of an excipient that should be within a specified range to ensure product quality. Tergus has several quantitative tools, such as rheology and viscosity, to evaluate topical excipients and understand the impact of these material characteristics on the final product, resulting in a robust formulation.
