On 3 February 2025, the UK’s Medicines and Healthcare products Regulatory Agency (MHRA) launched a consultation asking for stakeholders’ views on draft guideline in relation to the regulation of individualised mRNA cancer immunotherapies (Draft Guideline).
The aim of the proposed guideline is to establish a clear and streamlined regulatory pathway to authorisation so that these highly innovative products can be made available to patients quickly, without compromising any assessment of safety. While the primary focus of the Draft Guideline is individualised messenger Ribonucleic Acid (mRNA) cancer immunotherapies, MHRA suggests that the regulatory and scientific principles considered might be broadly applicable to other disease indications (including rare diseases) or technologies that could benefit from personalisation or individualisation. It also states that the Draft Guideline will be updated when experience of other technologies (peptides, non-integrative DNA and polymer deliver systems) is available.
In terms of regulatory assessment of individualised mRNA cancer immunotherapies, the Draft Guideline provides clarification of the data which should be included in marketing authorisation (MA) applications and, importantly, confirms that an individualised medicine may, in some circumstances, be granted an MA under the Human Medicines Regulations 2012 (HMRs), even where the product includes an individualised component tailored to the requirements of a specific patient.
There is currently substantial interest in the use of mRNA technology to develop individualised treatments for cancer. The current consultation is therefore of interest to companies focussing on this and other individualised therapies.Continue Reading The UK’s MHRA launches consultation on draft guideline on individualised mRNA cancer immunotherapies
