Some CDMOs may well respond to this example by positioning by themselves as experienced experts for use, devoid of advising the consumer on more info the strategic worth of the proposed work deal. From your CDMO’s viewpoint, it'd be far better to provide the agreement whatever the high quality with the development program. Should the consumer requests a security research for just a drug solution or drug material batch that is adequately supported by a past study, some CDMOs may well motive that it's not their accountability to disagree Together with the client.
All things considered, the sponsor sets development technique, and is particularly the party interacting with regulatory companies for that drug’s development. Be aware that regulatory authorities keep each get-togethers responsible for Conference cGMP needs.
