CMC that holds up under inspection.

We help biotech and advanced therapy teams take a process from development to commercial supply, and prepare the records, people and sites to defend it in front of regulators, partners and courts.

Six areas where we do the work ourselves

Every engagement is led by a senior practitioner who has run the process, not just reviewed it.

CMC strategy and regulatory support

Development to filing

Read more about this service

We build the chemistry, manufacturing and controls story that reviewers want to read: a defined process, justified specifications and a control strategy that matches the risk.

  • IND / IMPD and BLA / MAA Module 3 authoring
  • Comparability and change protocols
  • Gap analysis against current guidance
  • Regulator meeting preparation

Expert witness

Disputes and due diligence

Read more about this service

Independent technical opinion on manufacturing quality, GMP compliance and process failures. Reports are written to be understood by a judge or tribunal, and withstand cross-examination.

  • Expert reports and joint statements
  • Root-cause review of batch failures
  • Technical due diligence for investors
  • Testimony and deposition support

Technology transfer

Sponsor to CDMO, site to site

Read more about this service

We plan and run transfers so that the receiving site reproduces your product, not an approximation of it. That means clear process knowledge, realistic timelines and agreed acceptance criteria before the first batch.

  • Transfer packages and risk assessments
  • CDMO selection and technical oversight
  • Engineering and PPQ-readiness runs
  • Analytical method transfer

Audit and inspection preparation

Pre-approval and routine

Read more about this service

We audit you the way a regulator would, then close the gaps with you. Teams are coached on how to present their systems clearly and honestly, in the room and in the back room.

  • Mock FDA, EMA and MHRA inspections
  • Supplier and CDMO qualification audits
  • Data integrity assessments
  • Response writing for 483s and findings

Clinical and commercial manufacturing

Phase 1 through launch

Read more about this service

Hands-on support to keep supply on schedule while the process matures: batch record design, deviation management, process validation and the quality systems that carry a product from clinic to market.

  • Person-in-plant oversight
  • Process validation and PPQ strategy
  • Quality agreements and QMS build-out
  • Launch-readiness reviews

Cell and gene therapy: where the process is the product

Autologous, allogeneic, viral vector or non-viral, small changes in manufacture shift potency and safety. We work with teams who need CMC rigour without losing speed.

Vectors and starting materials
Lentiviral, AAV and plasmid supply strategy, and qualification of critical raw materials.
Cell therapy processes
CAR-T, TCR, NK and stem cell workflows, including closed and automated platforms.
Potency and release testing
Assay strategy, qualification and the link between potency and clinical response.
Chain of identity and logistics
Vein-to-vein planning, cryopreservation, shipping validation and patient scheduling.
Regulatory pathways
Expedited designations, ATMP classification, and comparability across process changes.

How an engagement runs

Short, scoped, and written down. You always know what we are doing, why, and what it will produce.

  1. Scoping call

    Thirty minutes, no charge. We tell you honestly whether we are the right team.

  2. Rapid assessment

    A one to two week review of your documents, data and risks, ending in a ranked action list.

  3. Delivery

    We embed with your team or work independently. Weekly written status, no surprises.

  4. Handover

    Everything is documented so your team can run without us. We stay on call if you want us to.
