When & Why To Outsource

Working with a CDMO can be a tactical or  strategic decision that enables sponsors to remain competitive, responsive, and innovative in a complex, highly regulated global industry. Typically, sponsors turn to external partners for strategic or operational reasons. Additionally, over the past decade, biotechs have focused on staying lean, virtual, and rely entirely on outsourcing.

 

Virtual Biopharma Models

Virtual biopharma companies with no internal laboratories or manufacturing assets represent a growing industry trend. These companies depend on outsourcing partners for every aspect of drug development; thus, finding the right outsourcing partners and proactively managing CDMO relationships is crucial to their success.

 

Strategic Motivations

CDMOs provide specialized expertise for everything from small molecules, to particularly for highly technical or emerging fields, including biologics, mRNA platforms, and cell and gene therapies. For instance, a small biotech creating its first biologic may require end-to-end capability from its CDMO partners.

Speed-to-market is paramount, and a CDMO with existing infrastructure can develop or manufacture a new drug much faster than a company can build in-house capabilities. Frequently, CDMOs integrate development and manufacturing for increased agility, accelerating timelines for highly competitive therapeutic areas.

Additionally, sponsors must strategically prioritize their CAPEX. Building GMP-compliant facilities from the ground up plus personnel expenses equals a high CAPEX commitment, which is infeasible for early-stage or resource-constrained companies. However, even large pharmaceutical companies wish to preserve capital for pipeline expansion, licensing, or other strategic priorities.

CDMOs also provide improved supply chain flexibility. Partners with global footprints and multi-site capabilities mitigate supply chain risks, manage regional market requirements, and offer greater scalability.

 

Operational Drivers

Many pharmaceutical companies turn to CDMOs to fill gaps in internal operational capacity. Challenges like rapid growth, new product launches, or demand surges can strain existing operations. For example, a mid-sized company with a fast-paced pipeline may seek an external partner to help develop a new product line.

Regulatory compliance and regionalization further complicate drug development. Meeting the expectations of the FDA, EMA, or other local authorities requires region-specific expertise and facility alignment. Companies looking to enter the global market benefit from partnering with CDMOs that are well-versed in local GMP requirements and supply logistics.

CDMOs Vs. CMOs Vs. CROs: Understanding The Landscape

This guide focuses on CDMO partnerships, but the pharmaceutical industry relies on several types of external partners:

• CDMOs offer development and manufacturing services for drug substances and products, including formulation, analytical testing, scale-up, and commercial production.
• CMOs (contract manufacturing organizations) provide manufacturing activities without upstream development support. Companies may prefer a CMO if they have completed early development in-house or with another partner.
• CROs (clinical research organizations) specialize in clinical trial design, execution, and data analysis.
• Hybrid models combine development and manufacturing with additional support services like regulatory consulting.
• Full-service providers manage the entire drug development lifecycle, from preclinical research to commercial supply.

Key Functions Outsourced To CDMOs

Sponsors can work with CDMOs at any stage in the drug development lifecycle, and the partnership’s scope varies according to the sponsor’s internal capabilities and those at the CDMO, program complexity, and product type.

 

Early-Stage Development

Early-stage development outsourcing often includes formulation, in which the drug delivery methods, excipients, and dosage forms are selected and optimized. Small biotechs may need CDMOs to provide complete preclinical manufacturing services, such as small-batch production for toxicology studies.

CDMOs can also establish validated, phase-appropriate analytical methods to characterize the drug substance or product’s identity, potency, purity, and stability. These services support ongoing development and produce foundational data for regulatory submissions.

 

Clinical Supply Manufacturing

When sponsors are ready to initiate clinical trials, they commonly turn to CDMOs for clinical trial material (CTM) supply, manufactured under GMP conditions, to ensure that the format, dosage, and packaging are suitable for human use.

Scale-up and tech transfer are crucial at this stage. Processes suitable for lab or pilot scale must be adapted to accommodate larger production volumes without compromising product quality or consistency. A smooth tech transfer from sponsor to CDMO includes detailed documentation, cross-functional coordination, and risk mitigation planning.

 

Commercial Manufacturing

Once a new drug is approved, sponsors often partner with CDMOs for robust, efficient, and fully compliant commercial manufacturing. Sponsors may lack the infrastructure to produce the API or drug product commercially or wish to diversify their supply network.

CDMOs also offer downstream services like packaging and serialization, which are necessary for regulatory compliance and product traceability across regions.

 

Specialized Services

CDMOs can provide highly specialized services for sponsors with a specific capability gap to fill. For instance, highly potent active pharmaceutical ingredients (HPAPIs) require specialized handling, including containment facilities, engineered controls, and trained personnel to protect product integrity and worker safety.

Cell and gene therapies also demand specialized manufacturing platforms, viral vector production, and complex quality control methods. To maintain sterility, these therapies require containment and controlled environments like aseptic suites, isolators, and cleanrooms. Sponsors developing highly technical, innovative therapeutics can partner with CDMOs specializing in these capabilities.

The Future Of Outsourcing In Pharma/Biotech

The global CDMO landscape is rapidly growing and evolving to keep pace with market forces, innovation, and regulatory changes.

 

Consolidation And M&A

The CDMO sector has consolidated significantly in recent years, with larger companies acquiring specialized providers to expand their capabilities and geographic reach.

For large sponsors, this trend grants access to integrated service networks and advanced technologies but adds complexities when a CDMO's personnel, systems, or priorities shift. However, consolidation can negatively impact emerging biotechs when CDMOs grow too big and prioritize their largest customers. Small biotechs can lose leverage and get shut out of capacity. When selecting a CDMO partner, sponsors of all sizes should consider the company's stability, integration success, and how post-merger alignment might affect project execution.

 

Geographic Diversification

In today’s international market, global supply chain resilience is vital. CDMOs are expanding their operations across regions to reduce risks and meet local market requirements. Sponsors can leverage these global operations to produce therapies closer to their target markets and local regulatory authorities while enabling redundancy and continuity planning.

 

Demand For Modality-Specific Expertise

Creating complex, novel modalities like mRNA, antibody-drug conjugates (ADCs), cell therapies, and oligonucleotides requires dedicated handling, containment, and process development capabilities. Sponsors developing advanced therapies need CDMO partners with demonstrated expertise, appropriate infrastructure, and a robust, relevant regulatory track record.

 

Regulatory Expectations For Outsourced GMP Compliance

Many regulatory agencies stress that sponsors cannot outsource GMP compliance. Sponsors are accountable for their product’s quality, safety, and efficacy, regardless of manufacturer. Clear oversight models, quality agreements, and audit trails must be maintained.

Likewise, CDMOs must continuously prepare for inspections and align with global GMP standards. Sponsors are increasingly using formalized governance structures and quality metrics to meet regulations.

Common Outsourcing Models & Business Strategies

Outsourcing is not a one-size-fits-all solution. Companies choose between various business models and objectives depending on their development stage, internal capabilities, and long-term goals.

 

Fee-For-Service Vs. Time & Materials Vs. Risk-sharing

Sponsors have options from fee-for-service to risk-sharing models for their financial agreement with the CDMO.

The most commonly used model is fee-for-service. In this arrangement, sponsors pay for specific deliverables like manufacturing runs, stability studies, or analytical method development. Sponsors often prefer this model because it offers predictability and transactional clarity.

For time and materials (TM) arrangements, sponsors pay the CDMO according to the hours worked and materials used. This method is commonly used in early development or undefined-scope projects because it offers flexibility. However, it can be difficult to budget precisely.

 

Sponsors relying on TM arrangements maintain oversight through detailed billing and time tracking. Once the project scope is clearly defined, TM arrangements can transform into fixed-price or milestone-based models. Risk-sharing models are the least common method but are gaining popularity, especially for innovative or high-risk programs. In this model, sponsors share clinical or commercial upsides with the CDMO in exchange for reduced upfront costs or co-investment in development.

 

Dedicated Capacity Vs. Flexible Resource Models

Next, sponsors must consider capacity strategy. Dedicated capacity gives sponsors exclusive access to a CDMO’s specific lines, suites, or equipment, which grants control and scheduling priority. However, this method often comes with long-term commitments and increased costs.

A flexible resource model uses a shared infrastructure and just-in-time scheduling to maximize agility and cost-effectiveness. The ideal approach depends on the project’s predictability, volume, and strategic importance.

 

Strategic Partnerships Vs. Transactional Engagements

The sponsor-CDMO relationship may entail a long-term strategic partnership or a temporary, transactional engagement. In a strategic partnership, the sponsor and CDMO share goals and align governance, often through joint steering committees, multi-program frameworks, and frequent touchpoints. On the other hand, a transactional engagement is appropriate for a single project with limited scope, focusing on execution over integration.

Risks, Challenges, & Mitigation Strategies

Outsourcing provides invaluable support to pharma companies of all sizes. However, working with a CDMO introduces operational and strategic risks.

 

Tech Transfer Delays

Tech transfer is complex, and delays are costly. Incomplete documentation, unclear roles, or poor planning can be avoided through early engagement, collaborative planning, and detailed transfer protocols.

 

IP Protection Concerns

Trusting an external partner with proprietary methods, data, or formulations requires more than a leap of faith. Robust contractual safeguards, defined data access controls, and selecting partners with strong reputations for integrity mitigate IP risks.

 

Supply Chain Bottlenecks

Supply chain risks, including raw material shortages and logistical issues, are all too common. Sponsors should collaborate with CDMOs to identify alternate suppliers, build a buffer inventory, and diversify sourcing strategies.

 

Quality Oversight

Sponsors and CDMOs share responsibility for product quality and regulatory compliance. Routine audits, performance metrics, and transparent quality agreements support transparency and help sponsors quickly identify and react to issues.

 

Capacity Shortfalls

CDMOs may experience demand surges or limited production slots, creating bottlenecks. Advanced forecasting, flexible agreements, and strong cross-functional planning help ensure capacity aligns with the program’s needs.
