Source of Contract development and manufacturing organisation

{{Infobox concept | name = Contract development and manufacturing organisation | subtitle = Supply chain role | image = facility.svg | Abbreviation = CDMO | Function = Development and manufacture to a customer specification | Consequence = Brand and manufacturer are frequently different }} A '''contract development and manufacturing organisation''' ('''CDMO''') develops processes and manufactures material to the specification of a customer who sells it under their own name. The arrangement is ordinary across the pharmaceutical and fine-chemical industries and is not in itself remarkable.{{r|ich_q7}} Its consequence for anyone reading supplier documentation is that the organisation named on a catalogue is not necessarily the organisation that made the material. A brand may be a manufacturer, a distributor of its own contract-manufactured material, or a reseller of another's — and the documentation may not distinguish these.{{r|iso9001}} The distinction matters for [[Lot traceability|traceability]] rather than for quality as such. Contract-manufactured material with an intact record chain is fully traceable; the failure mode is a chain broken at the transfer, which is a records question. See [[Repackaging]].{{r|ich_q7}} == What a CDMO does == Services span process development, analytical method development, scale-up, manufacture and, in some cases, fill-finish. A customer may buy any subset: a fully developed process transferred in, or a molecule and a target specification with everything else contracted out.{{r|ich_q7}} For peptides the capability that matters is [[Solid-phase peptide synthesis|synthesis]] at scale with the associated [[Preparative HPLC purification|preparative chromatography]], since the purification step is the one that requires the largest capital equipment. A house able to synthesise but not to purify at scale is limited to crude supply, and the distinction shows up in the specification a customer can be offered rather than in any claim about capability.{{r|usp1503}} Quality responsibility is defined by a quality agreement between the parties. In regulated manufacture the marketing authorisation holder remains responsible for the product regardless of who made it, and the agreement allocates the practical obligations.{{r|ich_q7}} == Consequences for reading documentation == A [[Certificate of analysis|certificate]] identifies the organisation that performed the determinations, which may or may not be the manufacturer and may or may not be the seller. Where the three differ and the document names only one, the others are simply not established by the document.{{r|iso9001}} | Named on the document | What it establishes | |---|---| | Testing organisation | Who performed the determinations | | Manufacturing site | Where the material was made | | Seller | Who is selling it | Most research-chemical certificates name one of these. That is a limitation of the document rather than evidence about the arrangement behind it, and inferring a specific structure from a document's silence is unsound. Where a claim about in-house manufacture is made, it is checkable in principle against corporate registration and facility records — the kind of documentary review described at [[VendorInvestigate]] — and not checkable at all by analysis of the material.{{r|reports}} == Why the arrangement is unremarkable == Contract manufacture is the normal structure of the fine-chemical industry, including for approved medicines. Treating it as inherently suspicious is not supportable, and a supplier that contracts out manufacture is not thereby doing anything irregular.{{r|ich_q7}} What is worth attention is consistency between what is claimed and what is documented. A specific claim about a facility, a certification or a capability is a checkable claim; a general impression conveyed by photographs and adjectives is not. This wiki's supplier articles accordingly describe documentary practice and, where sources permit, corporate facts, rather than inferring manufacturing arrangements that no available source establishes.{{r|reports}} == References == {{reflist}} <ref name="ich_q7">International Council for Harmonisation, ''Q7: Good Manufacturing Practice Guide for Active Pharmaceutical Ingredients'' (2000).</ref> <ref name="iso9001">ISO 9001:2015, ''Quality management systems — Requirements''.</ref> <ref name="reports">PeptidePedia Wiki community test-report tally, 2024–2026 (self-reported; see [[Project:Sourcing_guidelines]]).</ref> <ref name="usp1503">United States Pharmacopeia, General Chapter <1503>, ''Quality Attributes of Synthetic Peptide Drug Substances''.</ref> == See also == * [[Custom peptide synthesis]] * [[Good manufacturing practice]] * [[Lot traceability]] * [[Repackaging]] * [[VendorInvestigate]] {{DEFAULTSORT:Contract development and manufacturing organisation}} [[Category:Contract manufacturers]] [[Category:Manufacturing and supply]] [[Category:Supply chain integrity]]
