There are an increasing number of T cell-based therapeutics moving through clinical trials. These immunotherapies hold tremendous promise and much of the clinical trial data has been impressive. As these therapies have progressed toward larger trials and commercialization, focus is shifting from proof of concept to consistent and sustainable manufacturing…
It’s not surprising that many scientists are creatures of habit. After all, the “re” in “research” often feels like it stands for “repeatedly”. This attitude means that more often than not, scientists will develop a preferred “go-to” protocol. These are the ones that have been run countless times over the years, and become the protocol to learn for anyone new to the group…
GMP (Good Manufacturing Practice) growth factors and cytokines designed for therapeutic manufacturing are a critical component in defined medias. To date, the Cell Therapy industry has accepted the term GMP for this reagent class despite the fact that there is no direct oversight by regulatory authorities. These proteins are intended to be used during further manufacturing and do not come in direct contact with the patient. In fact, Cell Therapy manufacturers need to take steps to ensure that reagents used for further manufacturing are removed before the cells can be used in the clinic. In addition, FDA-regulated, clinical grade proteins that can be directly used as therapeutics may also be described as GMP, leading to confusion of the term “GMP” within different contexts…
Multiple buffers in a wide range of formulations are required to produce a single biopharmaceutical. Because of the large volumes required, buffer preparation can easily become a bottleneck in production. Traditionally, buffers are prepared manually in the volume needed according to specific recipes. Due to the large quantities used, buffer management requires careful planning and considerable floor space is required for the preparation and storage of such large buffer quantities. In addition to high labor and facility space cost, there is a risk of human error and variability associated with such a time-intensive manual activity. Buffer variability can affect both quantity and quality of the final product…
In the development of biopharmaceuticals there are times when an off the shelf affinity chromatography medium is unavailable or isn’t highly selective for the target molecule being purified. It is possible then to design a custom chromatography solution by coupling a specific ligand to a pre-activated resin…
Manufacturing biologicals is tricky. A major concern is the risk of microbial contamination, jeopardizing product safety and causing high costs. But there are solutions for decreasing the risks. Making monoclonal antibody (mAb) drugs? Safety first. In releasing a biomedicine, the last thing a biopharma company wants is for people to be harmed. This makes the risk of bioburden, and how it can be prevented, a major issue for drug safety…
Since the 1980’s monoclonal antibodies have revolutionized medicine and become a vital tool in fighting many diseases. While there are many new monoclonal antibodies in the clinical trial pipeline, there are also some innovative drugs made from just an antibody fragment. Due to the multi-domain structure of antibodies, it is possible to create smaller antibody fragments that still include the antigen-binding domain. Antibody fragments have some advantages over full-length antibodies and several antibody fragment-based biotherapeutics are in clinical research. Several antibody fragments have been approved and are commercially available, including: ReoPro®, Lucentis®, and Cimzia®.
Single-pass tangential flow filtration (SPTFF) technology from Pall Life Science is a versatile concentration approach for biotech, vaccine and plasma industry applications. Patented Cadence™ SPTFF technology offers a total solution for inline volume reduction and/or concentration, in-process dilution/de-salting, high concentration formulations, and processing of fragile molecules, crucially enabling integrated, streamlined and continuous bioprocessing initiatives.
Join our webinar on May 23rd at 1pm EDT, when moderator Kevin Marino and presenter Jon Petrone provide an overview of SPTFF technology, including case studies where this novel technology was applied to enhance processes and reduce bottlenecks in production.
Many industries have adopted a one-piece flow approach (continuous manufacturing) to leverage the core reductions in inventory, increased operational flexibility, and greater product consistency and quality that it delivers. However, biopharmaceutical manufacturers have been slow to put continuous processing theory into practice due to the highly-regulated nature of the industry.
On June 14th at 1pm EDT, Peter Levison, PhD will moderate as Mani Krishnan, PhD and Marc Bisschops, PhD examine the evolution of interest in continuous bioprocessing, the advances being made in today’s market, and how the regulatory authorities are responding. Mani will also offer insight into the technological challenges of implementing continuous bioprocesses, and potential regulatory questions surrounding batch definition, bioburden control, virus clearance, scale-up/down, defect perturbation, design space, etc.; he will also propose effective mitigation strategies for a successful transition to continuous bioprocessing.
Reviewing Continuous Chromatography Solutions, and the Effect the Number of Process Columns has on Specific Productivity and Binding Capacity
Continuous multi-column chromatography (MCC) has been gaining increasing interest as an enabling bioprocessing technique that allows for increases in specific productivity (g/L/hr) and operating binding capacity (g mAb/L sorbent) over traditional batch solutions. With recent advances, users have reported an increase in cost savings stemming from reduced resin volumes, lower buffer consumption, and increased resin usage.
Mark Pagkaliwangan presents on July 18th at 1PM EDT, with David Johnson moderating, as they discuss MCC solution advances with processes utilizing two columns or more. They will explore how the total number of columns used in a process can affect performance, and how titer and flowrate can be optimized with more columns for greater efficiency and productivity.
Expansion of MSCs for Translational Medicine using NutriStem® MSC Basal Medium and PLTMax® Human Platelet Lysate
Thursday, May 25, 2017, 11:00 AM ET
Speakers: Lia Thornberry Kent, Biological Industries USA
Vanesa Alonso-Camino, PhD, Mill Creek Life Sciences
One of the biggest challenges in Cell Therapy-based regenerative medicine is the difficulty of expanding mesenchymal stem cells (MSCs) in vitro. Traditionally, fetal bovine serum (FBS) has been used as the main supplement for the in vitro culture of MSCs. However, the use of xenogeneic elements, particularly bovine-sourced materials, to culture human cells intended for clinical applications involves a series of potentially fatal risk factors, ranging from immunogenic responses against exogenous antigens to the transmission of diseases.
Human platelet lysate (hPL) derived from normal human donor platelets provides a xeno-free alternative to FBS as a supplement for vitro expansion of human cells for both research and clinical applications. In this webinar, we present a new clinically-relevant MSC culture medium comprised of NutriStem® Basic Medium supplemented with PLTMax® to culture MSCs. MSC NutriStem® Basal Medium supplemented with PLTMax® demonstrates faster growth kinetics than media supplemented with other commonly used reagents, such as human AB serum or FBS.
Attendees will learn the basics of growing human MSCs in MSC NutriStem® Basal Medium supplemented with PLTMax®, as well as the capabilities of this medium to promote high cell viability, chromosomic stability, and expansion.
