PART I: HPAPI Market Forecasts and Manufacturing Challenges

In this two-part blog series, Alcami Senior Director of Global Manufacturing Science and Technology, Adam Kujath, discusses the market forecasts and the main manufacturing challenges involving highly potent APIs.

The highly potent active pharmaceutical ingredient (HPAPI) market is one of the fastest growing CDMO submarkets, approaching a 9 percent compounded annual growth rate (CAGR). There is a continued industry focus on pipeline development oncology drugs, which by nature of indication is producing compounds that are increasingly potent.

HPAPI Market Forecast
Increased awareness and toxicological diligence around new chemical entities (NCEs) are resulting in a higher number of molecules being classified as highly potent. Additionally, specific technologies, such as antibody drug conjugates (ADCs) requiring cytotoxic small molecule warheads, are driving the need for more specialized facilities with high containment for broad synthetic applications, but also conjugation and filling capabilities.  

HPAPI controls


The impact to CDMO’s is two-fold: increased demand for capacity in process development and manufacturing, and broadened capability requirements. The expanded demand and increased technological specialization drive further fracturing of the supply chain. It is not uncommon, as an example, to see an ADC have separate suppliers for the API, the monoclonal antibody, the bulk conjugation, and the final fill finish. While there is a high level of specialization required to execute on each phase, there is also a high level of commonality and natural efficiency that can be achieved with an integrated approach.  This can make an end-to-end platform even more appealing, but harder to find, when considering outsourcing. Regardless, all phases require investment in high containment engineering controls to ensure both patient and employee safety, yet few suppliers offer it. Having facilities and expertise in each operational area (API, drug product, and testing) as well as experience in the engineering, development, and execution of high containment manufacturing creates an advantage.
