Challenges and Advances in Downstream Purification of Biopharmaceuticals

The biopharmaceutical industry is facing demands for cost reductions in medications in developed countries with aging populations, as well as in developing countries with growing middle classes.  The advent of biosimilars has led to increased competition from other countries.  In addition, regulatory constraints require enhanced potency, efficacy and safety while there is a need for rapid approval and deployment of life-saving vaccines, and novel gene-based and stem cell-based therapeutics.

There is a great deal of interest in the development of novel downstream processes to accelerate production, reduce process steps, process footprint, buffer and energy use, and regulatory burdens.  Single use devices, low cost affinity media, membrane chromatography, process intensification, in-line validation and other approaches are being explored.  Our group has pioneered the use of synthetic peptide libraries for the identification of low cost ligands with high affinity and selectivity for a wide variety of protein targets. In addition, we are pursuing inexpensive, high-throughput, high binding-capacity non-woven membranes as solid supports for product or contaminant capture. These developments might enable “truly continuous” purification strategies based on flow-through separation steps relying completely on disposable membranes.

Thermal Processing Enhances Drug Delivery of Poorly Water Soluble Drugs – Process Selection

Thermal processing, including hot melt extrusion and KinetiSol® Dispersing, are useful processes for formulating drugs with low water solubility in order to improve their properties, such as wetting, dissolution and bioavailability.  Polymers are typically employed in these processes to formulate the drug as an amorphous solid dispersion.  Thermally labile drugs and drugs that have a high melting point (e.g., greater than ~200°C) are often not suitable for processing by hot melt extrusion.  KinetiSol® Dispersing, a high energy fusion process not requiring an external heat source, offers a suitable alternative to these difficult to formulate drugs.  Processing times differ in terms of minutes versus seconds, for hot melt extrusion and KinetiSol® Dispersing, respectively.  This talk will discuss hot melt extrusion and KinetiSol® Dispersing in terms of process selection and limitations, and will include examples of formulations exhibiting enhanced properties.

Fundamental Principles and Enabling Technologies for the Design of Batch and Continuous Chromatography Processes

Chromatography methods are highly selective separation methods, which are required for manufacturing of many biochemicals and biopharmaceuticals. Advanced chromatography methods for manufacturing, however, are not taught in conventional science or engineering curricula. Many chromatography processes in industry are designed empirically, with poor yield, productivity, and solvent efficiency. In this talk, the fundamental principles of batch and continuous chromatography will be explained. Enabling technologies and tools, which will help understand, analyze, simulate, design, and optimize various types of chromatography processes, will be discussed. The knowledge and the advanced computer tools are useful for improving the efficiency of existing processes or designing more efficient processes to reduce manufacturing costs.

Design and Modeling of  Roll to Roll Continuous Lyophilization  System

Authors: Miko Cakmak. Alina Alexeenko

Abstract:  In this talk we will  present a novel design of continuous roll to roll Lyophilization System  and metrology tool.  The machine designed has dual purpose. One is to produce  thin layers of lyophilized materials and laser packaging. In the second function it was designed with metrology tool that will track weight loss, thickness during lyophilization. A basic modeling of the process  was developed help predict the thickness changes and extent of lyophilization.

Innovative technologies for spray drying and characterization of pharmaceutical solids

Abstract: The 21st century has seen many innovations in manufacturing of pharmaceutical solid, with purposes to improve production efficiency, formulation performance and product stability. As an example, spray drying has been increasingly employed for production of both small- and large-molecule pharmaceutical solids, attributed to the superior production efficiency and formulation flexibility. Over the past decade, there are some innovative technologies have been developed for spray drying. Also, some cutting-edge techniques have been applied to characterize physico-chemical properties of spray-dried solids, aiming to optimize the manufacturability, stability and therapeutic efficacy of the spray-dried products. This talk will summarize some advances in spray drying and characterization of pharmaceutical solids.

Pharmaceutical Manufacturing in the Era of Patient-Centric Medicine

Biomedical advances are making it possible to quantitatively understand why is it that the same medication does not work the same in every patient, thus rendering the long-standing drug therapy practice of “one-dose-fits-all” outdated, for an increasing number of drugs. The pharmaceutical industry faces the challenge of how to apply the latest advances in process understanding achieved in recent years, along with the accompanying high standards of product quality achieved, as it moves into the era of patient-centric medicine (PCM). Namely, the “retooling” needed to create a product that instead of being a blockbuster, is a large collection of “mini-busters.” This requires the ability to cost-effectively produce product variations, covering an arbitrary number of different doses, and with a range spanning roughly two orders of magnitude (based on metabolic variability). Similar challenge arises for the manufacture of patient-specific, non-fixed combination products, bound to change over time even for the same patient, involving different number and APIs.

A platform for the design and manufacture of oral dosage forms (“pills”), developed to satisfy the patient-tailored (or subpopulation-tailored) requirements of PCM is presented. The approach is a paradigm shift, whereby pills are conceived as Integrated Systems, rather than as traditional compacts of powder blends. The manufacture of this new type of multiplexed pill (“3 D Pill”) is analogous to the manufacture of 3D Integrated Circuits. The oral dosage forms, modular in design, are made by assembling prefabricated components in 3 D stacks, where each prefabricated component performs a specific, pre-determined pharmaceutical function. Each prefabricated component is a polymer composite wafer, whose particular function in the assembly is determined by the type of material embedded with the polymer (active pharmaceutical ingredient, solubilizer, disintegrant, absorption enhancer, pH modifier, ID/anti-counterfeiting element, etc.). The Integrated Systems approach to drug manufacturing makes it comparatively to traditional manufacturing, a much simpler task to add or refine performance attributes of the pill, and/or quality related attributes to the dosage form by incorporation of additional/different functional composite wafers. The 3D Pill concept is fully patient-centric, such that precise dose adjustment, as well as drug release characteristics, can be achieved within the same platform, in order to meet the therapy requirements of the individual patient. The Integrated Systems approach to pharmaceutical manufacturing fully exploits the advantages of things like continuous manufacturing and QbD, provided that a slight but important shift in focus is adopted, thus suggesting that the “retooling” needed in industry to fulfill PCM needs, is rather one of “mindset,” and not so much one of facilities, processes or know-how.
