Leaders in Chemistry, Manufacturing & Controls
More programs stall on chemistry, manufacturing, and controls than on efficacy. A specification set too tight to pass validation, a process change with no comparability data behind it, a Module 3 that contradicts the batch records: none of these are clinical problems, and all of them can hold a filing. CMC is also uniquely unforgiving of timing. What is right for a first-in-human IND is wrong for a commercial NDA, and evidence you failed to collect in Phase 1 cannot be recovered at registration. We build CMC programs that are phase-appropriate at every stage and defensible at the end, so the manufacturing story is an asset in your submission rather than the reason it waits.
CMC is not a set of independent tasks; it is a single narrative that has to stay coherent as your product moves from grams to metric tons. We follow that arc through six stages, each building the evidence the next one depends on. Jump to any phase, or read it as the timeline it is.
The phase-appropriate roadmap: what evidence each milestone requires, and what to build now versus defer without creating a gap later.
Process and formulation development framed by QbD: critical quality attributes, critical process parameters, and the design space to defend them.
Validated methods, justified specifications, and a stability program that supports the shelf life you actually need to claim.
The control strategy that ties CQAs to controls, plus process validation and comparability that survive a pre-approval inspection.
Module 3 and the 2.3 Quality Overall Summary authored to tell one consistent story across IND, IMPD, NDA, BLA, and MAA.
Post-approval change management under ICH Q12: variations, comparability, and an established-conditions strategy that keeps supply moving.
The hardest CMC judgment is not what to do; it is what not to do yet. Over-invest early and you burn cash characterizing a process you will change anyway. Under-invest and you reach registration with a hole no amount of money can backfill. We set the phase-appropriate plan against your regulatory milestones: the evidence each submission genuinely requires, the studies that must start early because their data takes years to mature, and the decisions that can safely wait. It is the roadmap every later stage is measured against.
Regulators no longer accept a process that works; they expect one you understand. Quality by Design reframes development as a search for the relationship between what you do and what you get: which attributes actually matter to the patient, which parameters move them, and how wide the operating window can be before quality is at risk. We run substance and product development that produces this understanding, so your specifications and control strategy rest on characterization rather than on a handful of lucky batches.
Analytical methods are the instruments through which a regulator sees your product, and a specification is a promise you make about every future batch. Set an acceptance criterion too tightly and routine variation becomes an out-of-specification investigation; set it loosely and you cannot justify it against the clinical experience. We develop and validate the methods, justify each specification against real batch and stability data, and design the stability program so the shelf life you claim is the shelf life you can prove.
By registration, the question shifts from can you make it to can you make it reliably, at scale, forever. The control strategy is the answer written down: how each critical attribute is controlled, by which test, at which step, with what justification. Process validation demonstrates it holds across the ranges you claim, and when the process has changed since your clinical batches, comparability proves the product did not. This is the evidence a pre-approval inspection exists to test, and the most common reason a CMC package fails one.
The reviewer never sees your labs. They see Module 3, and they read it looking for the seams: a specification in 3.2.S that the stability data in 3.2.P will not support, a Quality Overall Summary that oversells what the body of the dossier proves, a batch analysis that contradicts the process description. We author the module and the 2.3 summary as a single coherent argument, reconcile every number against its source, and prepare the responses to the CMC questions that arrive after filing.
A commercial product is never static: sites move, suppliers change, processes improve, and every change has to reach dozens of markets on their own regulatory clocks without ever interrupting supply. ICH Q12 gives you tools to manage this deliberately, through established conditions and post-approval change management protocols that pre-agree the reporting category before you need it. We build the lifecycle strategy that turns each change from a supply risk into a routine variation, filed on time, in the right category, in every market.
The lifecycle above holds for most programs. Two situations rewrite it: advanced modalities whose CMC is the hardest part of the whole program, and a manufacturing crisis that arrives without waiting for the roadmap.
For a small molecule, the structure is defined and the process serves it. For a biologic, a cell therapy, or a gene therapy, the process largely defines the product, and a change you cannot fully characterize can be a change to the drug itself. Comparability carries far more weight, potency assays are often the critical unsolved problem, and agencies expect a control strategy matched to that complexity. We bring modality-specific CMC experience to the programs where manufacturing, not the clinic, is the gating risk.
A confirmed out-of-specification result on a pivotal batch, a CMC-driven Complete Response Letter, a comparability failure after a process change, a 483 that threatens supply: these do not arrive on schedule, and they are rarely just technical. We run CMC remediation under pressure, diagnosing the real root cause, separating the science problem from the documentation problem, and building the response that protects both the filing and the supply chain.
CMC judgment comes from having run the development, sat in the plant, and answered the agency's questions. Our teams combine former CMC reviewers with industry scientists who have taken products from first IND to commercial validation, so the advice reflects both how it is assessed and how it is actually made.
Consultants who have reviewed Module 3 for the FDA and EMA. They know which questions the quality assessor asks first, and what turns a routine review into a deficiency.
Process chemists, analytical leads, and manufacturing heads who have owned CQAs, run validation campaigns, and stood in front of a pre-approval inspection.
The rarest CMC skill is knowing what is enough for the stage you are in. Our teams calibrate the work to the milestone instead of gold-plating every phase.
Small molecules, peptides, biologics, cell and gene therapies, and combination products, across drug substance, drug product, and the analytical work that ties them together.
