Quick answer: CROs, CMOs and CDMOs support different stages of pharmaceutical development and manufacturing. A CRO (Contract Research Organisation) typically focuses on research and clinical development, a CMO on manufacturing, while a CDMO combines development and manufacturing services to support products from early development through to commercial manufacture.
Developing a new pharmaceutical product is a complex process that often requires expertise across research, development and manufacturing.
While some pharmaceutical and biotechnology companies have these capabilities in-house, many choose to partner with specialist organisations to access additional expertise, technologies and manufacturing capacity.
Three of the most common partners are Contract Research Organisations (CROs), Contract Manufacturing Organisations (CMOs), and Contract Development and Manufacturing Organisations (CDMOs).
Understanding the distinct role each organisation plays can help companies choose the right partner for their stage of development, whether that’s progressing a molecule through clinical trials, scaling up manufacture or preparing for commercial supply.
In this article, Mark Vlasic, Business Development Manager at Douglas CDMO, explains the different roles CROs, CMOs and CDMOs play within pharmaceutical development and manufacturing, and why selecting the right partner can have a lasting impact on the success of a development programme.
“Choosing the right outsourcing partner isn’t just about finding someone who can complete the next stage of your project. It’s about finding a partner who understands where your product is heading and has the scientific, development and manufacturing expertise to support you as it progresses.”
Mark Vlasic, Business Development Manager, Douglas CDMO
Although there can be some overlap between services, the primary focus of each organisation is quite different.
What is a CRO?
A Contract Research Organisation (CRO) supports pharmaceutical and biotechnology companies during the research and clinical development stages of a product’s lifecycle.
Rather than investing in specialist research infrastructure or expanding internal teams, companies often work with CROs to access expertise in areas such as clinical trial management, regulatory affairs and data management.
Depending on the project, a CRO may provide services including:
- Clinical trial design and management
- Clinical monitoring
- Regulatory support
- Medical writing
- Data management and biostatistics
- Pharmacovigilance
By partnering with a CRO, companies can access specialist knowledge and additional resources while helping to keep development programmes moving efficiently.
What is a CMO?
A Contract Manufacturing Organisation (CMO) specialises in manufacturing pharmaceutical products.
Once a formulation has been developed, companies may engage a CMO to manufacture clinical trial material or commercial product without investing in their own manufacturing facilities.
Typical CMO services include:
- Clinical trial manufacturing
- Commercial manufacturing
- Process scale-up
- Manufacturing capacity
- Regulatory manufacturing support
For many companies, particularly those with established formulations, partnering with a CMO provides access to manufacturing expertise and production capacity while allowing internal teams to remain focused on research, development or commercial activities.
That said, not all CMOs offer the same capabilities. Some specialise in particular dosage forms, technologies or therapeutic areas, making it important to select a partner with experience relevant to your product.
What is a CDMO?
A Contract Development and Manufacturing Organisation (CDMO) brings pharmaceutical development and manufacturing together under one roof.
Rather than working with separate organisations for development and manufacture, companies can partner with a CDMO throughout much of the product lifecycle. Depending on the services required, this may begin with formulation development and continue through analytical development, clinical trial manufacturing and commercial manufacture.
A CDMO may offer services such as:
- Formulation development
- Analytical development
- Process development
- Clinical trial manufacturing
- Commercial manufacturing
- Packaging
- Supply chain support
For many companies, this integrated approach offers practical advantages. Working with a single partner can improve continuity between development and manufacturing, reduce technology transfer requirements and simplify project management as products progress towards commercialisation.
When should you choose a CRO, CMO or CDMO?
The right partner depends on where your product is in its development journey and what expertise you need at that stage.
If your focus is on generating clinical data, navigating regulatory requirements or managing clinical trials, a CRO is typically the right choice.
If your formulation has already been developed and you’re looking for manufacturing capacity, a CMO may be all that’s required.
However, if you’re developing a new product and need both development and manufacturing expertise, working with a CDMO can often provide greater continuity throughout the programme.
By bringing formulation development, analytical services and manufacturing together, a CDMO can help reduce the number of handovers between organisations, making it easier to retain technical knowledge as a product progresses from development through to commercial manufacture.
As Mark explains:
“Every product presents different technical challenges. Understanding those challenges early, and considering how development decisions will affect manufacturing later, can help avoid unnecessary complexity as a programme progresses.”

Choosing the right partner for your product
The right outsourcing partner depends on your product, your stage of development and the expertise you need. CROs, CMOs and CDMOs each play an important role, and choosing the right company for your product can help streamline development, manufacturing and the path to commercial success.
When evaluating a potential partner, consider questions such as:
- Do they have experience with your dosage form?
- Can they support the services you need, now and as your programme progresses?
- What experience do they have with technology transfer and scale-up?
- Are they familiar with the regulatory requirements for your target markets?

What does CDMO stand for?
CDMO stands for Contract Development and Manufacturing Organisation. A CDMO provides integrated pharmaceutical development and manufacturing services, supporting companies from formulation development through to clinical trial manufacturing and commercial manufacture.
What is the difference between a CRO and a CDMO?
A CRO focuses primarily on research and clinical development, providing services such as clinical trial management, regulatory support and data management.
A CDMO, on the other hand, supports the development and manufacture of pharmaceutical products. Depending on its capabilities, a CDMO may provide formulation development, analytical services, clinical trial manufacturing, commercial manufacture and packaging.
Is a CDMO the same as a CMO?
No. A CMO focuses on manufacturing pharmaceutical products, while a CDMO combines pharmaceutical development and manufacturing within a single organisation.
For companies developing a new product, working with a CDMO can provide greater continuity as a product progresses from development through to commercial manufacture.
When should a pharmaceutical company choose a CDMO?
A CDMO is often the right choice when a company requires both development and manufacturing expertise. By working with a single partner throughout multiple stages of development, companies can often simplify project management, reduce technology transfer requirements and maintain continuity as products move towards commercial manufacture.
What should you look for when choosing a CDMO?
Every project is different, but some important considerations include:
- Experience with your dosage form and formulation challenges
- Scientific and technical expertise
- Analytical development capabilities
- Clinical and commercial manufacturing experience
- Quality systems and regulatory track record
- Technology transfer expertise
- Capacity to support future scale-up and long-term supply
Selecting a CDMO isn’t simply about today’s project. It’s also about choosing a partner with the capabilities to support future development and manufacturing requirements.

What is a CDMO responsible for?
A CDMO is responsible for turning a promising formulation concept into a manufacturable, scalable and approvable product. This involves formulation, analytical and process development, manufacturing expertise, and the regulatory support required throughout development and commercialisation.
Should you choose a CDMO or separate CRO and CMO partners?
A CRO typically manages research activities such as preclinical and clinical studies, while a CMO focuses on manufacturing. A CDMO combines development and manufacturing services, providing continuity from formulation and process development through to commercial production. This can reduce technology transfer between organisations, helping minimise delays, knowledge loss and scale-up challenges. However, companies with an established product and manufacturing process may only require a CMO for production.
