There are many biopharmaceutical CMOs in the industry who would gladly take your promising molecule and develop it to the best of their ability. But when your company’s future is dependent on getting that molecule through testing, scale-up, regulatory filings and production as quickly and efficiently as possible – there are only two things that matter when choosing a biopharm CMO for your product – experience and expertise.

This is where a CMO like Laureate Biopharma in Princeton, NJ can provide the qualities needed to bring your biopharmaceutical product to market with the assurances only an experienced player in this market can provide.

Background and Overview

“We’ve always been in the biopharmaceutical space,” says Michiel Ultee, Ph.D., the company’s Chief Scientific Officer who has been with company for most of its 30 year history. “We are particularly adept at recombinant production of mammalian cell produced proteins, and over the years we’ve added different capabilities enhancing our analytical capabilities, our purification capabilities and added larger bioreactors.”

Laureate’s range of services for biopharmaceutical customers begins right after the discovery phase. “Pure research or discovery is not our area,” says Ultee. “However, we do enable the companies that provide these services to turn their R&D into a product. We do all the additional development, the scale-up, the cGMP production and testing required before it’s suitable for a safe and effective product. All we need to know is the identity of the protein and we can produce a cell line and take it from there.”

For companies that are further along the road to production, Laureate can transfer that product into their facility, including products that are ready for final filling.

Laureate views this tech-transfer process as critical to ensure success. “It’s a critical process, “says Ultee. “We have to understand their molecule very well – they have to understand our process – there is a lot of exchange of information and collaboration between scientists.” To ensure that all Requests for Proposals (RFPs) from potential clients are handled in a timely and comprehensive manner, the company follows up all RFP’s with a technical call with the new customer’s scientists to make sure all parties involved understand the project’s scope, parameters and goals. A project management group is brought in as early as possible to detail the expected timeline, project activities, and responsible subject matter experts and map out what needs to be done when.

The Quest for Quality

For any biopharmaceutical CMO implementing the right systems and strategies to ensure a quality product is paramount to success. At Laureate, discussions with customers related to quality systems and strategies are really dependent on the project’s current stage.

Lisa Cozza, Laureate’s Vice President of Business Development explains that since every customer is unique and projects come to Laureate at different stages – the quality systems discussion can take many different forms. “With companies where the goal is to get into the clinic or animal studies, the focus is on the immediate technical challenges of the protein and its production, and less on quality systems. In other scenarios, we have clients that might already have their bulk drug substance and are looking for fill/finish, or they are looking for process improvements at larger scale or to launch out of our facility.  In those cases, the quality conversation starts right away – and a quality audit is done by the potential customer early on to vet our facilities and capabilities.”

“Pretty much all of our customers do a quality audit,” says Ultee. “They want to be sure that when they develop a product with us it will be done under GMP and will meet regulatory approval for their clinical testing program.”

A Complex World

With biopharmaceuticals growing in importance not only to the financial health of the pharmaceutical industry but also to the health of consumers - one might think that the complexity of making biopharmaceuticals has increased over the years.

“I don’t know if it has become more complex,” says Ultee. “I think it has become more rigorous, as people have come to understand proteins better, we have come to know what matters more and what matters less. We have evolved from the process making the product to the product being sufficiently well-defined and characterized that process changes can be accommodated. There is a lot of analytical testing that is done now which is a change from the early days of biopharmaceutical development – where you had a process and you couldn’t change it because the process defined the product.”

“It is definitely not what it was 20 years ago” says Cozza. “The expectations of the regulatory agencies have become so comprehensive – that although it may be easy, physically, to go out there and make some product, the additional hurdles of regulatory, analytical comparability and reporting make for a much tougher assignment. This has evolved the talent pool as well. Today it has become easier to find manufacturing talent – where in the past it wasn’t easy – but meeting the tougher analytical and technical reporting requirements require a different talent pool.”

 

 

 

The Impact of Technology

Laureate’s history in the biopharmaceutical manufacturing business has given them a unique insight as to how technology has changed over the years and also how vendors of biopharmaceutical manufacturing equipment have improved their products.

“We have close relationships with the equipment and materials vendors we work with,” says Ultee. “Improvements in bioreactor design, cell-line construction, cell-culture media and feed solutions, have resulted in dramatic increases in cell-culture titers. These have allowed us to ensure that the cells both grow well and produce well.”

“On the downstream side – we have seen a tremendous shift in purification strategies which have transformed from overnight slow processes in cold rooms many years ago to the current high-speed, synced, two or three step a day processes – that produce a much purer product. This is the result of advances in separation sciences.”

Perhaps the greatest development in biopharmaceutical manufacturing has been the advent of single-use/disposable technologies.

“Disposables have advanced,” says Ultee. “The early things that were disposable – pipettes and roller bottles were good because it eliminated the need to wash them. Shake flasks are disposable and bioreactors are now disposable – and pre-packed chromatography matrices that allow us to work very rapidly – they are not necessarily disposable - but they offer a lot of advantages.”

“The use of disposable flow paths where you do not have to worry about product change over, is really ideally suited to CMO’s.” says Cozza.

Laureate has been using single-use disposable fluid paths in their fill/finish area for the last 12 years, citing reduced changeover times and elimination of carryover from one product to another as two of the main benefits of this technology. In addition to using disposables in their fill/finish operations Laureate also employs the technology in its bioreactors. In fact the company regularly does beta testing on the newest single-use bioreactor designs in order to stay current.

“We want to stay current and innovate and keep up with latest technology because it makes for a faster and a more robust process,” says Ultee.

Biosimilars and Biobetters

In the biopharmaceutical industry there is perhaps no hotter topic than that of biosimilars and biobetters.

With a vested interest in the race to develop and produce biosimilars and biobetters, Laureate is keeping a watchful eye on this rapidly developing topic.

“The production of biosimilars is taking up a lot of capacity,” says Cozza. “There are a lot companies and CMOs collaborating on these programs. At the same time" Cozza continues, “the acceptance of using CMOs to get bulk drug products developed and launched is growing.”

Cozza says that Laureate is getting a lot of interest from “virtual” companies who would never consider building a facility – and therefore must rely on the experience and expertise of a company like Laureate.

“I think with biosimilars you are going to see the same thing that happened with small molecule production – a lot of it will eventually go to CMOs,” says Cozza. “The biosimilars race is going to be very similar to the generics race.”

“I have a very optimistic view on biosimilars and biobetters," says Ultee. “In the clinical space – there are a lot people trying and they will come to CMOs like us to try out their product. I also think it will focus interest in good analytical capabilities – which we have added in the last few years – we have doubled the size of our analytical team. We have put a lot of focus on that in part because of the advent of biosimilars – and the related molecules – biobetters. I’m more interested biobetters because, like biosimilars, I think the indication for the drug is already known, but you just don’t have to make it match precisely to the innovator drug. There are therefore improvements you can introduce to provide for higher potency, longer half-life, etc. You can make improvements that maybe the innovator had also thought of but didn’t do because the drug in its present form was doing well.”

Future

With a well-established reputation as being a leader in biopharmaceutical manufacturing, Laureate is looking towards the future with an eye on growth and to continue to supply the level of service and quality it has become known for in the industry.

Speaking to the company’s current and future capabilities, Cozza has this to offer, “We are a stand-alone CMO that can provide services across the entire CMC chain. You can come to us with a protein and we will help you file your IND or BLA with the material we generate and data we supply. The fill/finish and regulatory services we provide sets us apart. A lot of CMOs have some of the same things – we all have process development and tanks of various sizes – but what we’ve done, including investments in our analytical capabilities, quality systems and our facility, enable our scientists to stay on the leading edge of new and challenging products. This keeps us unique.”

“I see us as being one of the top tier CMOs in five years due to our investments and growth. Our leadership has pushed the envelope toward growth and has made a lot changes and innovations,” says Ultee.

At the end of the day, what really matters to companies looking for a CMO is if they can get the job done - at Laureate it’s an everyday occurrence.

“I believe our science sets us apart,” says Ultee. “We have a reputation for tackling difficult proteins.”

“Clients come to us with big challenges,” concludes Cozza, “and we help them succeed.”
