Key considerations when choosing a CDMO for your project

Companies operating in the pharmaceutical and biotech sectors must evaluate a range of critical factors prior to partnering with a contract development and manufacturing organization (CDMO).

Selecting and working with the right CDMO can significantly impact drug development projects’ chances of success, so it is essential that companies be well-informed before committing. This article features a comprehensive guide to understanding these key considerations.

Understanding specific needs

Any company looking to work with a CDMO should begin by defining its own product’s development requirements. For example, a company may be in preclinical, clinical, or commercial phase. It may also be prepared to engage an inexpensive CDMO for initial work and accept additional costs and time for tech transfer at a later phase.

Some projects require comprehensive end-to-end services, while others would benefit from support in specific areas, such as formulation or scaling up production.

Many CDMOs specialize in specific stages of development. Clearly identifying a project's stage and the services required allows companies to align their needs with a CDMO that offers complementary expertise.

This is an important consideration because a mismatch between a company’s needs and the CDMO’s capabilities can result in cost overruns, delays, and even regulatory setbacks. Precise alignment ultimately saves both time and money.

Evaluating experience and specialization

Not every CDMO will have equal experience across every dosage form, molecule type, and therapeutic area. It is important to thoroughly explore a potential CDMO’s portfolio and look for case studies or references related to the type of drug to be developed.

If a CDMO has successfully navigated projects involving similar drugs, it is much more likely to be able to effectively manage a project’s unique challenges.

Regulatory experience is also essential. The CDMO should have a track record of working with the EMA, FDA, or other regulatory bodies in a company’s target markets. It is also important that the CDMO is familiar with relevant regulatory frameworks to efficiently navigate compliance.

Scalability of operations

A drug’s production requirements tend to change as it moves through development stages, so it is important that the CDMO is able to scale from clinical trial production to full commercial manufacturing. With this in mind, it is also important to evaluate a CDMO’s capacity to accommodate increased production volumes while maintaining quality standards.

Companies should inquire about a potential CDMO’s manufacturing facilities and equipment, ensuring that it offers the capacity and flexibility to adjust to any potential production increases.

A good CDMO will employ scalable technologies that can help streamline the process, such as leveraging single-use systems in biologics. If a CDMO is unable to scale production in line with its client’s needs, launches could be delayed, and costs could increase, particularly during critical phases like commercial manufacturing.

Companies looking for less expensive options may opt to work with an early-phase CDMO that focuses on early-stage drug development, including preclinical and Phase I/II clinical trials.

Early-phase CDMOs tend to be lower cost because these CDMOs do not require the expensive infrastructure required for large-scale commercial production. Their procedures are also simple, because the testing of safety and efficacy is their primary concern.

Early-phase CDMOs can deliver more rapid timelines that lower overhead, though technology transfer costs are incurred when advancements in the drug necessitate the expertise of a late-phase CDMO.

These additional costs may be worth accepting, however, because late-phase CDMOs can often offer specialist knowledge around topics like mass production and distribution. The technology transfer process can also help companies update their small, experimental batches into consistent production capable of delivering higher volumes.

Regulatory compliance and quality standards

Quality control is non-negotiable in drug manufacturing, so it is important that a CDMO adheres to good manufacturing practices (GMP) and that it successfully passes regular inspections by regulatory agencies like the FDA and EMA.

Companies should investigate a potential CDMO’s compliance history in order to ensure that it meets stringent quality management systems (QMS).

Transparency in quality processes is also key, including how a potential CDMO manages inspections and audits. The CDMO should have a demonstrable history of timely regulatory approvals, and warning letters or compliance issues should be highlighted and thoroughly considered.

Communication and project management

Effective communication is the foundation of a successful partnership. Clear, consistent, and transparent communication is key to managing expectations and timelines while avoiding potential setbacks.

A CDMO should provide a dedicated project manager who will serve as a primary contact throughout the project, ensuring transparency and keeping the company informed of key milestones, updates, and challenges.

A small biotech should expect a CDMO to treat its project with the same care as the projects of big pharma clients in its portfolio.

Location and supply chain capabilities

Geographical proximity has a major impact on logistics and project management, so companies should consider the CDMO’s location in relation to their own operations, particularly if the project in question involves global markets.

A good CDMO should understand specific regional regulations where a product will be marketed and be able to manage cross-border supply chains without delays. A CDMO with robust global capabilities can help streamline issues such as shipping times, customs clearance, and differences in regulatory jurisdictions.

Cost transparency and flexibility

A CDMO’s pricing model should be transparent and clear. Some CDMOs work with opaque pricing structures, charging hidden fees for services like regulatory submissions, quality testing, or material procurement. It is important to request detailed cost breakdowns prior to engaging a CDMO, ensuring that the contract accounts for any potential changes in project scope.

A CDMO should also be flexible enough to manage unforeseen issues without major budget implications. It should also be able to adjust costs if the project needs to pivot or expand.

Innovation and technological capabilities

CDMOs may be able to improve efficiency and lower costs by investing in innovative technologies and leveraging cutting-edge methods and technology. This can offer a range of advantages, but a company should also confirm whether or not these organizations will cover the costs of implementing these technologies or if the client must cover this cost.

A good CDMO will also leverage automation or data-driven analytics to improve manufacturing processes. These technologies can significantly reduce human error, streamline operations, and offer faster turnaround times.

Cultural fit and partnership philosophy

Cultural fit should never be overlooked because a company’s partnership with a CDMO is a long-term engagement that can span years to decades. The CDMO should align with the company’s goals, values, and underlying way of working. A robust cultural fit leads to fewer disruptions and an overall smoother, more productive, long-term relationship.

Conclusion

Working with the right CDMO can essentially make or break a drug development project.

Considering the critical factors outlined here will allow companies to select a partner that meets their technical and regulatory requirements while aligning with their long-term goals.

6 CDMO Selection Tips From An Experienced Start-Up

By Louis Garguilo, Chief Editor, Outsourced Pharma

Does your process to select a CDMO emerge from within and without?

If you are looking for more details, kindly visit Small Molecule CDMO.

Ryan Crisman, cofounder and Chief Technical Officer, Umoja Biopharma, Inc., says it should.

“To begin with, it's always important for your selection model to have an internal expert who can ‘fact check’ the CDMOs,” Crisman advises.

Featured recently in these pages, Umoja is a clinical-stage company advancing a new cell-therapy approach to immunotherapy, specifically for solid tumors.

The company also has a small-molecule platform. Crisman says cofounder (Phil Low, Co-Chair of Umoja’s scientific advisory board; Presidential Scholar in Drug Discovery and the Ralph C. Corley Distinguished Professor of Chemistry at Purdue University), had been doing small molecule research for decades. He provided a contact to take the lead in assessing CDMOs.

“Al Ritter came on as a consultant with his 35 years of experience in development and manufacturing of small molecules. He went out and did all our initial service-provider assessments,” says Crisman, who himself is an experienced biopharma facility professional.

“Al was so valuable we ended up hiring him full time. He oversees our small molecule pipeline development.”

Umoja was established in , and a piece of Ritter’s early advice proved prescient:

For a U.S.-based company, keep partners close to home – meaning within North America.

That cornerstone guidance helped Umoja avoid the worse of the COVID and supply-chain challenges that soon transpired. “It was critical for control of our supply chains,” says Crisman.

Ritter also set an example for Umoja (and now Outsourced Pharma readers) to follow.

Crisman says:

“Al goes into CDMO discussions thinking of building a strategic relationship, and trying to understand, ‘What is the mission of this CDMO?’

“He’s taught us we must ensure we aren’t just a cog in the wheel, another revenue stream. He clarifies whether the CDMO is actually interested in troubleshooting, and working collaboratively.”

However, Crisman clarifies, “This isn’t a knock on those who aren’t. CDMOs know what is good for their business model, and what is not, just like the prospective client should.”

Obtaining this assurance of alignment is critical.

As well as advancing its own pipeline, Umoja’s mission includes potentially going out to CDMOs with designs of having some of those providers adopt Umoja’s novel approach and technology for lentiviral vector development.

They’ve been picking CDMOs as service providers, and soon as technology partners.  First, Umoja is perfecting and de-risking that technology by building out its own facility.

Once that is accomplished, it will then require an intricate transfer to CDMOs, close cooperation and troubleshooting, and further learning together.

How will Umoja know which of these CDMOs will fit that bill?

Crisman says Ritter (and the experience of others in the company) has taught them if you ask the right questions, “you can actually figure out quickly what type of CDMO they are.”

“Already, we’ve learned there are really good, established CDMOs out there that want to be a partner, and some that see you as a dollar sign and prioritize – or de-prioritize – based on the size of the company. Those don’t last very long.”

Which brings us to our first four tips:

  1. Have an internal outsourcing expert (who can be a consultant); ensure the entire company learns from them.
  2. Stay as close to home as possible to mitigate supply-chain (and other) risks.
  3. Verify the CDMO’s “mission”; obtain an assurance of alignment with your goals.
    1. Accomplish this initially by asking the right questions, and thinking in terms of strategic partnerships.
  4. When necessary – considering all factors, e.g. funding, external expertise (or lack of), etc. – build your own facility as a component of our strategic plans.

Below we’ll describe two more tips:

  1. Select CDMOs based on your specific program needs, and their specific capabilities
  2. Verify CDMO track records with others; meet directly with CDMO project-team members to verify skills and longevity.

Who Passes The Exam?

In the development space, says Crisman, for us it’s been “quite a mix of big, small, new and more experienced CDMOs – with that caveat they are all located in North America.”

And not the relationship kind, but the actual chemistry involved with Umoja’s programs helps drive these selections. “We found the smaller shops had more of an established research arm ready to invest the time and effort to help us understand the chemistry,” he says.

In some cases, these smaller – more focused and specialized – CDMOs have unique analytical tools, “so we could look at the chemistry from different angles.”

Conversely, Crisman says, “The big CDMOs, especially during the recent supply-chain challenges, tend to have the upper hand in regard to more access to vital items, such as vials for drug products.”

So why not contract to get the best of both breeds? To de-risk various aspects of the outsourcing process, that’s what Umoja has been looking to do.

But in all cases, it’s been a solid consideration of the internals at Umoja that drive where and with whom to externalize.  

Next, Crisman avers, when it comes to comparative price-shopping, “the entire CDMO world is highly competitive. The pricing ranges tend to be in the same ballpark.”

Therefore, price alone won’t ferret out many CDMOs from others – which adds importance to these enumerated tenets of the Umoja outsourcing strategy.

(And when there are notable price discrepancies, it’s important to learn why. Perhaps the CDMO didn’t fully understand the project, or you aren’t understanding all that is essential for ultimate success. It’s worth following up.)

So with price off the table (relatively), Crisman knows “it ends up with sponsors having to carefully access a CDMO’s history.”

One way to understand that track record is to independently ask other sponsors who have worked with a CDMO; another is to seek references directly from the CDMO – and follow up closely on those. (Another is to access our CDMO Leadership Awards, presented each year in April.)

Within that CDMO history, skilled worker availability and retention should be carefully noted; you can learn a lot by directly meeting those who would be working with you.

“The skilled-worker profile is something we are hyper-focused on,” says Crisman.

That … and all of the above.
