Plain English summary of protocol

Background and study aims
There is a growing understanding that the effectiveness and safety of many regularly prescribed medications can be influenced by common genetic changes. This is a concept known as pharmacogenetics. Although there are guidelines in place for genotype-guided prescribing for many gene-drug pairs, very few are used in practice as previously, genetic testing could not be turned around in a clinically relevant timeframe.

The PROGRESS trial is part of a programme of work to introduce pharmacogenetic testing in general practice and to assess the implementation of this new service. A panel of genes with known implications for a range of commonly prescribed medicines has been selected and an informatic solution to help guide prescribing has been developed called the Genomic Prescribing Advisory System (GPAS). This pharmacogenetic testing and advisory system will be implemented at a number of GP practices to establish whether genetic testing can be delivered to support genotype-guided prescribing in a clinically relevant timeframe.

Who can participate?
The study is recruiting over two phases. In phase one (months 1-6), five “early-adopter” sites will invite patients who are being considered for 4 classes of medicine as part of their routine appointment. These medicines include Statins, Proton Pump Inhibitors, Selective Serotonin Reuptake Inhibitors, and Tricyclic Antidepressants.

What does the study involve?
Participants would be required to donate a blood or saliva sample for genetic testing, with the aim to return results to the GP within 7-10 days. Patients will be alerted by their GP once results are available and a prescription can be issued. In the second phase (months 7-18), additional sites across the country will be included. The study is designed to identify any challenges in implementing this service as well as collect information on patient and health care professional’s attitudes to using the service.

What are the possible benefits and risks of participating?
Participants will benefit from having access to a new clinical service which is under consideration by the NHS, which allows medicines to be optimized for an individual based on their unique genetic information. By taking part, information will be generated which may inform safer, more effective prescribing for the current problem but also remain in the participant's health record to inform any future prescribing decisions. The intervention is low risk, with a single blood or saliva sample required for DNA testing.

Where is the study run from?
The study is run by Clinical Geneticists based at Manchester University NHS Foundation Trust, in partnership with the North West Genomic Medicine Service Alliance (GMSA). Recruiting sites will be a selection of GP practices, initially in the North West of England (Phase I) and later rolled out to GP practices across the UK (Phase II).

When is the study starting and how long is it expected to run for?
April 2022 to April 2026

Who is funding the study?
The study is funded by NHS England with support from the National Institute for Health Research (NIHR) (UK)

Study acronymPROGRESS
Study objectivesTo assess the implementation of a pharmacogenetic guided prescribing service in UK primary care.
Ethics approval(s)Approved 20/03/2023, London - Surrey Research Ethics Committee (Level 3, Block B, Whitefriars, Lewins Mead, Bristol, BS1 2NT, UK; +44 2071048388; surrey.rec@hra.nhs.uk), ref: 23/LO/0201
Health condition(s) or problem(s) studiedAssessment of pharmacogenetic guided prescribing across a range of commonly prescribed medicine classes, initiated in primary care.
InterventionThe PROGRESS trial is designed to assess the viability and utility of a pharmacogenetic-guided prescribing service in Primary Care. Potential participants attending their GP practice for a routine appointment, who are being considered for a pre-defined list of commonly prescribed agents, will be offered testing for a panel of genes with known implications for this range of medicines. Genetic results will be fed back to the referring clinician via a novel informatic solution developed as part of this programme, known as the Genomic Prescribing Advisory System (GPAS). Data will be collected around the proportion of participants with actionable pharmacogenetic information and service performance-related outcomes such as turnaround times for testing and metrics related to how results were used.
Intervention typeGenetic
Primary outcome measureThe Pharmacogenetic Clinical Utility Metric (Defined as the proportion of patients across the study cohort with a CPIC Level 1A variant related to the medicine which triggered recruitment to the study) – determined through genetic testing as part of study
Secondary outcome measures1. The proportion of patients recruited to the study who had their pharmacogenetic results returned within 10 working days (Monday – Friday) of enrolment. The day of enrolment represents day 0. Collected from patient records.
2. Average turnaround time from enrolment to PGx results being available on GPAS. Collected from patient records.
3. The proportion of enrolled patients whose GPAS system record was accessed by a member of the clinical team. Collected from patient records.
4. The proportion of participants who had a prescription issued before the pharmacogenetic results were available. Collected from patient records.
5. Average time from recruitment to prescription. Collected from patient records.
6. The proportion of patients who had at least one prescription amended over the course of the study based on the pharmacogenetic data. Collected from patient records.
7. Average turnaround time from enrolment to results being integrated into the Electronic Health Record (EHR). Collected from patient records.
8. Proportion of participants who have a delay (more than 10 working days) in results being integrated into the EHR. Collected from patient records.
9. The proportion of enrolled participants for whom a clinical decision support notification was triggered. Collected from patient records.
10. The average number of clinical decision support notifications which triggered over the course of the study (expressed as per month/visit/prescription). Collected from patient records.
11. The proportion of participants who had a prescription issued before the pharmacogenetic results were available. Collected from patient records.
12. The proportion of patients on a given class of medicine who had their index medicine (i.e., the medicine which precipitated recruitment) changed at 1 and 6 months following prescription. This outcome will be compared against anonymized historical (non-genotyped) comparators, matched for demographics, from the Greater Manchester Care Record (GMCR). Collected from patient records.
