Funded PhD Opportunity Design & testing of a pharmacogenomic model to inform treatment decisions of rheumatoid arthritis patients
This opportunity is now closed.
Subject: Biomedical Sciences
The current treatment paradigm for rheumatoid arthritis (RA) involves the sequential use of disease modifying anti-rheumatic drugs (DMARDS). The efficacy and patient tolerability of each therapy is currently determined using a trial and error approach. Many patients therefore derive no clinical benefit, yet are exposed to a spectrum of side effects and increased disability risk .
There are several single nucleotide polymorphisms (SNPs) which are associated with treatment response to DMARDs. These include SNPs within the folate pathway for methotrexate, within cytokines for hydroxychloroquine, effecting acetylators for sulpsalazine, and influencing cytochrome enzyme activity for leflunomide.
The aim of this research therefore is to design and test the ability of a pharmacogenomic model to stratify RA patients into treatment groups which maximise drug efficacy and minimise toxicity.
Hypothesis: A pharmacogenomic machine learning model can accurately predict DMARD therapy response for RA patients.
1. To develop a comprehensive database of treatment and outcome data features.
2. To define a discrete multiplex panel of SNPs and methylated genes which influence DMARD metabolism.
3. To develop and test the accuracy of a DMARD treatment predictive model.
1. Detailed prescribing, drug efficacy and adverse event information will be extracted from patient medical notes for RA patients currently recruited (n=450).
2. A panel of candidate SNPs for the drugs of interest will be selected using PharmGKB, along with regulatory regions known to be subject to hyo/hypermethylation.
3. Data Analysis
a. Whole genome sequence data generated by third party provider (n=152*) will be screened for the selected panel of SNPs and methylation sites.
b. Data analysis will examine patient group stratification for each drug and outcomes relative to their pharmacogenetic profile. This data will be used to develop a predictive pharmacogenomic model for DMARD selection by machine learning methods.
c. An independent treatment and response blinded cohort of rheumatoid arthritis patients, (n=152*) also genotyped by targeted sequencing/methylation assay will be used to validate the predictive model sensitivity and specificity.

Vice Chancellors Research Scholarships (VCRS)
The scholarships will cover tuition fees and a maintenance award of £14,777 per annum for three years (subject to satisfactory academic performance). Applications are invited from UK, European Union and overseas students.
The scholarship will cover tuition fees at the Home rate and a maintenance allowance of £ 14,777 per annum for three years. EU applicants will only be eligible for the fees component of the studentship (no maintenance award is provided). For Non EU nationals the candidate must be "settled" in the UK.
