Due Diligence Support

icon

Every acquisition, divestment, or licensing deal in pharma and medtech carries regulatory risk. Missed post-approval commitments, undocumented manufacturing changes, incomplete dossiers, fragile supply chains: these are the issues that surface after close and cost real money. regenold provides the technical due diligence that deal teams need to price risk accurately and plan integration from day one. We review the dossiers, assess the quality systems, evaluate the pipeline, and deliver a clear picture of what you are buying.

Examples of How We Support

These are examples to illustrate the kind of work we do. The fastest route is usually a short call to understand your transaction and discuss how we can help.

Buy-side portfolio review

You are acquiring a marketed portfolio and need to understand the regulatory status across various markets before signing. We screen the marketing authorisations, post-approval commitments, and pending variations across all relevant territories, flag risks that affect valuation, and deliver a structured risk register your deal team can act on.

Pipeline asset assessment

Your PE fund is evaluating a mid-stage biotech with three pipeline assets and you need an independent view on probability of approval. We assess clinical data packages, CMC readiness, and regulatory alignment for each asset, identify the gaps that could delay or block approval, and map those risks to deal economics.

Sell-side divestment prep

You are preparing a pharma business unit for divestment and need to present a clean regulatory and quality package to prospective buyers. We run a sell-side regulatory review, identify and remediate documentation gaps, and compile a vendor due diligence package that withstands buyer scrutiny.

Rapid licensing review

A licensing opportunity has landed on your desk and you have 10 days to assess whether the product dossier is fit for EU submission. We conduct a rapid dossier review against CTD requirements, flag critical deficiencies, and provide a clear go or no-go recommendation with a remediation estimate.

On-site CMC assessment

Your deal team needs CMC and GMP expertise for site visits during a transaction, but your internal team is already stretched. We deploy qualified assessors for on-site evaluations of manufacturing facilities, quality systems, and supply chain arrangements, and deliver findings in a format your deal team can integrate directly into the investment case.

Understanding the Scope

Due diligence in pharma and medtech transactions involves multiple disciplines, and the same applies to transactions in adjacent regulated sectors such as food, food supplements, and cosmetics, where we have supported DD mandates covering product compliance, formulation, and market authorisation status. Financial, legal, and commercial due diligence are typically handled by specialist firms. Our scope covers the technical and regulatory dimensions: the product dossiers, manufacturing and quality systems, clinical and preclinical data, pharmacovigilance, supply chain, and operational readiness for integration.

We do not provide financial valuations, commercial assessments, legal opinions, or freedom-to-operate analyses. Where these disciplines intersect with regulatory or technical findings (for example, when a CMC gap has direct cost implications, or when a regulatory risk affects deal structure), we frame our findings so they can be directly incorporated into the broader transaction assessment as they can have a strong commercial impact on one's investment thesis and company valuation. For clients who need coordinated multi-disciplinary DD, we work alongside legal, commercial and financial advisors under a single project framework.

What We Do

Our due diligence work follows the transaction process timeline, from early screening through to post-merger integration planning. We assemble cross-functional teams matched to the scope of each deal and adjust depth and focus as information becomes available:

  • Screen target assets against public regulatory data (marketing authorisation databases, inspection records, safety signals, enforcement actions) to identify early red flags before VDR access is granted.
  • Review product dossiers for regulatory completeness and compliance, assessing CTD modules, approval conditions, post-approval commitments, and pending variations across relevant markets.
  • Evaluate CMC and manufacturing data, including process validation, analytical methods, stability programmes, comparability studies, and supply chain robustness.
  • Assess GMP and GDP compliance by reviewing inspection histories, quality system documentation, CAPA trends, and audit findings.
  • Analyse clinical and preclinical data packages for regulatory alignment, protocol design adequacy, GCP/GLP compliance, and readiness for upcoming milestones (CTA/IND, MAA/NDA).
  • Review pharmacovigilance systems, including PSMF structure, QPPV/LPPV arrangements, risk management plans, and signal detection processes.
  • Conduct on-site assessments of manufacturing facilities, QMS implementation, personnel competence, and documentation practices not accessible through the VDR.
  • Deliver structured risk reports with prioritised findings, red flags, remediation estimates, and actionable recommendations calibrated to the deal stage.

Our Workstreams

Due diligence scope varies by transaction. The workstreams below represent the core disciplines we deploy, individually or in combination, depending on what the deal requires.

Regulatory Compliance

Marketing authorisation status across markets. Post-approval commitments (renewals, PSURs, variations). Dossier quality against current CTD and regional requirements. Orphan designation and paediatric obligations. Regulatory risk exposure from pending guideline changes.

CMC & Manufacturing

Process validation and technology transfer readiness. Analytical method lifecycle. Stability data and shelf-life claims. Nitrosamine and elemental impurity risk assessments. Comparability data for site or process changes. Module 2.3/3 compliance.

Quality Systems & Supply Chain

QMS effectiveness against GMP/GDP requirements. Inspection and audit history (both regulatory and internal). CAPA closure rates and trends. Supplier qualification, single-source dependencies, and cross-border logistics risk. Subcontractor agreement compliance.

Clinical & Preclinical

Data package adequacy for planned regulatory submissions. Trial design and endpoint alignment with current guidance (ICH E8/E9). GCP/GLP/GCLP compliance across studies, CROs, and sites. Gap analysis against regulatory milestones.

Pharmacovigilance & Vigilance

PV system master file review. QPPV/LPPV arrangements and compliance. RMP adequacy. Safety reporting processes and timelines. For medical devices: vigilance system assessment under MDR/IVDR, including complaint handling processes, incident and trend reporting compliance, PMS plan adequacy, and PMCF/PMPF status. Assessment of post-market surveillance data integration into clinical evaluation and risk management updates.

Market Access & Integration Readiness

HTA alignment and pricing/reimbursement risk. Post-approval market entry barriers. Operational readiness for regulatory transfer, MA holder changes, and system integration. Personnel, IT, and process dependencies.

Where This Fits in the Development Journey

Due diligence is transaction-driven, not development-stage-driven. But the stage of the target asset determines what we evaluate and where the risks concentrate.

Discovery & Concept

Early-stage asset screening. Feasibility of regulatory pathway. Freedom-to-develop assessment for in-licensing candidates.

Preclinical

Non-clinical data package adequacy. GLP compliance. Toxicology programme completeness relative to planned clinical entry.

Design & Development

CMC readiness and scalability. Formulation and process development status. For devices: design history file completeness, standards compliance.

Clinical

Trial design and endpoint alignment with regulatory expectations. GCP compliance across sites and CROs. Data integrity. Probability of approval based on available evidence.

Regulatory Submission & Approval

Dossier completeness and deficiency risk. Authority interaction history. Approval conditions and commitments. Orphan or accelerated pathway status.

Launch & Market Access

MA transfer requirements. Pricing and reimbursement positioning. Supply chain readiness for commercial volumes. Labelling and local market compliance.

Post-Market & Lifecycle Management

Variation and renewal compliance. PV system and PSUR status. Post-market surveillance obligations (for devices). Lifecycle extension potential.

Product Type Considerations

Due diligence scope and focus shift depending on the product type being evaluated.

Small Molecules

Manufacturing process maturity. API sourcing and supply chain. Stability and shelf-life. Post-approval variation history. Generic competition landscape.

Medical Devices

Technical documentation completeness and quality under MDR Annex II/III: GSPR checklist compliance, clinical evaluation report adequacy, risk management file completeness, and labelling/IFU compliance. Notified Body relationship: certificate status, expiry dates, scope of certification, and history of NB findings or conditions. QMS assessment against ISO 13485, including design and development controls, supplier qualification, and CAPA effectiveness. PMS/vigilance system compliance: PMS plan adequacy, complaint trending, PMCF status, and incident reporting history. EUDAMED registration and UDI compliance. IVDR transition status for legacy IVDs: classification under the new risk framework, performance evaluation readiness, and transition timeline feasibility.

ATMPs and Cell/Gene Therapies

Manufacturing complexity and GMP for ATMPs. Hospital exemption status. Conditional MA obligations. Long-term follow-up requirements. Supply chain for starting materials.

Biologics and Biosimilars

Comparability and analytical similarity data. Cell line and manufacturing process characterisation. Cold chain and logistics. Biosimilar interchangeability status by market. Reference product patent landscape (flagged, not assessed by regenold).

Combination Products

Dual regulatory pathway requirements (MDR + pharma). Integration of device and drug dossier components. Human factors and usability data. Notified Body and competent authority coordination.

Pipeline and Pre-Approval Assets

Regulatory strategy credibility. Clinical development plan alignment with current guidance. CMC scale-up readiness. Probability-of-approval assessment calibrated to deal economics.

Frequently Asked Questions (FAQ) +

How quickly can you mobilise a DD team?

For standard transactions, we can have a scoped team in place within five to seven working days of engagement. For urgent situations (compressed deal timelines, competing bids), we have mobilised within 48 hours. Team composition depends on the scope: a single-product dossier review may need two to three specialists, while a multi-country portfolio assessment can require a cross-functional team of eight or more, drawing on regenold's own teams and regulanet® partners for local market expertise.

Do you work on both buy-side and sell-side mandates?

Yes. On the buy side, we assess targets and flag risks that affect valuation and integration. On the sell side, we help vendors prepare their regulatory and quality documentation for scrutiny, identify and remediate gaps before the process begins, and compile a vendor DD package that supports a smoother transaction. The disciplines are the same; the framing differs.

What is the difference between a site visit during DD and a formal GMP audit?

A due diligence site visit is exploratory and time-constrained. We review selected documentation, observe operations, and hold focused discussions with quality and operations personnel to form a preliminary risk picture. A formal GMP audit follows a defined methodology, covers a full scope against regulatory or internal standards, and produces findings with formal classification. During DD, site visits are typically the most we can do within the timeline. If findings from the visit indicate a need for a formal audit, we recommend it as a post-close workstream.

How do you handle multi-country portfolio assessments?

Through regulanet®, our global network of independent regulatory service providers. For each target market, we engage local experts who assess region-specific regulatory requirements, MA status, post-approval obligations, and market access considerations. regenold coordinates the overall assessment, consolidates findings, and delivers a single integrated report. The client has one contract and one point of contact.

Can you assess pipeline products that are still in clinical development?

Yes. For pipeline assets, we evaluate the clinical development plan against current regulatory expectations, assess CMC readiness for the next development milestone, and review the regulatory strategy for plausibility. We provide a probability-of-approval assessment based on the data available, the regulatory pathway chosen, and comparability with precedent approvals. This is not a statistical prediction; it is a structured expert assessment that highlights the specific risks and gaps.

What happens if data is incomplete or access is restricted during the process?

This is normal in DD. Sellers control the flow of information, and VDR access often comes in stages. We structure our work to provide useful outputs at each stage: an initial screening based on public data, a deeper assessment once VDR access is granted, and refinements as additional documents or Q&A responses become available. We are explicit about what we have reviewed, what we have not, and what the residual uncertainty means for the deal.

Do you provide integration planning support after close?

Our DD scope typically ends with the risk report and recommendations. However, many of the workstreams that arise post-completion of the transaction (MA transfers, PV system setup, QMS integration, regulatory submissions for the acquired portfolio) are core regenold services. Continuity from DD into integration is one of the advantages of working with a regulatory services firm rather than a generalist consulting practice: the team that identified the risks is available to resolve them.

How do your fees work for DD engagements?

DD is scoped and quoted on a per-project basis, reflecting the number of products, markets, and disciplines involved. We do not bill hourly with an open-ended estimate. At the outset of every engagement, we agree on scope, deliverables, timeline, and cost. If scope changes during the transaction (as it often does), we discuss and agree on adjustments before incurring additional cost.

What does device-specific due diligence cover that pharma DD does not?

Medical device transactions require assessment of the technical documentation (the device equivalent of the pharmaceutical dossier), the Notified Body relationship and certificate status, the quality management system against ISO 13485, and post-market surveillance compliance under MDR/IVDR. Key risk areas include: incomplete or outdated technical documentation that won't survive NB re-certification, certificates approaching expiry without a clear renewal pathway, IVDR transition gaps for legacy IVDs, and single-source supplier dependencies for critical components. We assess all of these as part of our device DD workstream.
