How to scale CMC capability without the cost of a permanent in-house team
There is a capability challenge that most development-stage pharmaceutical companies face at some point.
You need experienced CMC expertise. You need it across chemistry, manufacturing and controls, spanning process development, analytical, regulatory submissions and technical writing. But you do not need all of it all the time.
Hiring permanent headcount to cover that is expensive, inflexible, and often difficult to justify against a programme that is still evolving. This article sets out how to think about that problem, and what the alternative actually looks like in practice.
The shape of CMC demand in development programmes
CMC workload is not flat. It peaks sharply before IND or CTA submission, at scale-up and technology transfer, ahead of regulatory meetings, and when manufacturing issues arise that need rapid resolution. Between those peaks, the need drops considerably.
Most development-stage companies do not need a full CMC function year-round. They need depth at specific points in the programme. The mismatch between that reality and a fixed headcount model is where the cost problem originates.
Where CMC demand is highest
Pre-IND and pre-CTA: building the first regulatory CMC package
Pre-Phase 2/3: scale-up planning and manufacturing readiness
Technology transfer: moving between CDMOs or manufacturing sites
Regulatory responses: addressing agency questions on CMC sections
Programme rescue: resolving a CMC-related hold under time pressure
Why the default approach to CMC resourcing often fails
The instinct is to hire. A CMC director, a regulatory affairs specialist, a technical writer. The logic seems sound until you look at the numbers.
A permanent senior CMC hire costs well over 200,000 GBP per year once salary, benefits and employer overhead are included. Recruitment and notice periods mean it takes three to six months before they are in the role. And once hired, the cost is fixed regardless of whether the programme is at peak demand or sitting between milestones.
For companies with a single asset or a programme that is still some distance from commercialisation, that overhead is difficult to carry. And if the programme is delayed, restructured or paused, a fixed CMC team becomes a liability rather than an asset.
The problem with hiring to peak demand
High fixed cost: justified at submission, hard to unwind when the workload drops
Skills breadth: a small permanent team cannot credibly cover all CMC disciplines
Timing: recruitment takes three to six months. Regulatory timelines do not wait.
Flexibility: permanent headcount is the wrong structure for project-driven work
What outsourced CMC capability actually looks like
Outsourcing CMC capability does not mean handing over responsibility and hoping for the best. Done well, it means accessing a team of senior technical specialists who integrate with your internal team, know your programme, and take ownership of the CMC workstream at each stage.
The scope typically covers CMC strategy and programme planning, regulatory dossier preparation across IND, CTA, NDA and MAA, technical writing, process development and optimisation support, analytical method development and validation oversight, technology transfer, and CDMO management.
What distinguishes an effective outsourced CMC model from generic consulting is continuity. Your external CMC team should know your product, your regulatory history, and your CDMO relationships as well as any internal hire would. Familiarity is what makes the model work.

TDP provides outsourced CMC capability that integrates directly with your development team. Whether you need ongoing strategic support or targeted expertise at a specific programme stage, we work as an extension of your operation.
Five situations where outsourcing CMC makes the stronger case
1. You are pre-commercial or early-stage
For biotech and emerging pharma companies, building a full CMC team before you have revenue from a marketed product is hard to justify. Outsourcing gives you senior CMC expertise at the point you need it, without committing to fixed overhead your current stage cannot support.
2. Your workload is project-driven, not continuous
If your CMC needs are centred on a specific submission, a defined technology transfer, or a regulatory response, the work has a beginning and an end. External resource for a defined scope is almost always more efficient than hiring for it.
3. You have a capability gap your internal team cannot cover
Even well-resourced CMC functions encounter areas outside their direct experience. A novel formulation, a complex analytical method, or a demanding agency question may require specialist expertise your team does not hold. Outsourcing that component, while keeping your team in control of the broader programme, is a practical and widely used approach.
4. You are managing multiple assets
For companies with more than one programme, an outsourced CMC team can flex across assets rather than being tied to a single product. The same senior expertise is available wherever the demand is highest.
5. You need to move faster than hiring allows
CMC timelines do not wait for recruitment processes. A well-structured outsourcing engagement can be operational within days. When speed matters, outsourcing is often the only realistic option.
What to look for in a CMC partner
The quality of the partner matters as much as the decision to outsource. The people you bring in will contribute directly to your regulatory submissions and your CDMO relationships.
Questions worth asking before you engage
Do they have direct experience with your product type and your target regulatory markets?
Can they provide named senior individuals with verifiable CMC track records?
Do they take ownership of outcomes, or do they operate purely as a document resource?
Can they work embedded within your team, or do they operate at arm's length?
Do they understand the regulatory context behind the technical work, not just the technical work itself?
The last question matters most. CMC is rarely straightforward. The value of a strong external partner is technical depth combined with regulatory judgement. That combination is what produces submissions that clear review without unnecessary information requests.
Making the decision
There is no universal right answer on in-house versus outsourced CMC.
If your CMC challenges are specific, time-bounded, or outside your current capability, outsourcing is likely the faster and more cost-effective route. If your workload is continuous and your programme is at commercial scale across multiple markets, building in-house makes sense. For most development-stage companies, the right answer involves some combination of both.
The question worth asking is not which model is better in theory. It is which model is better for your programme, at this stage, given the work that actually needs doing.
If you are working through that question, we are happy to give you a direct view.
