The MHRA said that while the proposed new regulatory regime for POC products would link in to existing regulatory systems for medicines approvals, clinical trials, evaluation of regulatory compliance at manufacturing sites and safety monitoring, the “standard model” of regulation does not fit with the traits and requirements of POC products.
“A new regulatory framework is being considered to enable the safe development of POC products for supply to patients through clinical trial studies and then on to licensing, i.e. obtain a marketing authorisation underpinned by safety monitoring and minimisation of risks by the Medicines and Healthcare products Regulatory Agency,” the regulator said. “Such a framework requires control measures equivalent to those currently in place for medicinal products to ensure that POC products meet the necessary requirements for quality, safety, and efficacy.”
Life sciences expert Sarah Taylor of Pinsent Masons, the law firm behind Out-Law, said: “The UK is the first country in the world to propose a regulatory framework for POC products. However, it cannot exist in a vacuum. As the MHRA notes, the innovations are not just available in the UK and so equivalent regulatory approaches will be needed in other countries. The MHRA has said that it has initiated discussions with international regulatory partners, and it will be interesting to see how closely any resulting approaches align to ensure that these new products are made available to a wide number of patients.”
One of the traits of POC products are their short shelf-life. The MHRA said the shelf life of POC products can be calculated in “hours, minutes or less”, compared with the two to three years typical of conventional medicinal products. This means that POC products need to be manufactured “in very close proximity to the patient” and “at a large number of sites” rather than at a single manufacturing centre, and that traditional quality control testing and qualified person certification cannot take place prior to their supply. Instead, “control measures” are necessary “at the time of manufacture … to provide assurance of the quality of products followed by a rapid decision to either supply and administer or to reject the product”, according to the regulator.
The MHRA said: “Since most POC products have very short shelf lives they cannot be manufactured in advance or supplied to distant locations, some POC products may be manufactured for an individual patient. These mean that supply has to be by scale-out (i.e. by adding more manufacturing sites) and not scale up (i.e. by adding more capacity to a few existing sites). Experience with POC products in clinical development indicate that some will be manufactured at several hundred UK sites. It follows that inspecting and authorising each manufacturing site and naming all on each product’s marketing authorisation becomes a major and possibly insurmountable issue.”
To address this, the MHRA has proposed a system of regulation for POC products built around a ‘control site’ concept where most of its regulatory focus will be aimed. Under those plans, a single manufacturing site for a manufacturer’s POC products would be named on the clinical trial or marketing authorisation application and be “responsible for overseeing all aspects of the POC manufacturing system including the addition of new manufacturing sites and control of each manufacturing location and their activities”.
