What is clinical research?

Clinical research is the study of health and illness in people. This is often split into two groups:

  1. Observational studies

These studies help researchers to understand a situation through observation of a particular area of interest and may take the form of the following types of studies:

  • Surveys / questionnaires
  • Blood / saliva samples

2. Clinical trials

Clinical trials test new ways of preventing, detecting or treating disease or illness. Treatments might be:

  • New drugs or combinations of drugs
  • New surgical procedures
  • New devices
  • New behavioural intervention

Clinical trials can also test other aspects of care, such as ways to improve the quality of life for people with chronic illnesses.

Current clinical research opportunities

Autistic Spectrum

We are inviting adults who have a diagnosis of autism and experience anxiety to take part in a research study. The study is called STRATA (SerTRaline for AnxieTy in adults with a diagnosis of Autism). It has been co-produced with experienced clinicians, researchers, and autistic people to investigate the treatment of anxiety in adults with a diagnosis of autism. AWP is hosting this study but people can take part from anywhere in the UK.

You can learn more about what is involved in taking part by reading the participant information here.

Please read the information carefully and feel free to discuss it with family, friends, carers, or others if you wish.

To take part in this study you must:

  • be aged 18 years or over
  • have a diagnosis of autism (including variations such as Asperger syndrome)
  • experience anxiety for which you are willing to try treatment with medication
  • be able to complete online or paper questionnaires about things such as your anxiety, other symptoms, and healthcare usage
  • be able to provide informed consent to take part

How long does it take?

Participants will be enrolled to the study for up to 52 weeks (1 year), during which time they will be asked to take the study medication as directed, and complete four questionnaires (with their time reimbursed with a £10 voucher for each). In addition, there will be five brief safety check appointments to discuss how participants are getting on with the medication and carefully monitor any side effects. All study appointments can be done via video or phone call, or in person appointments (any travel expenses reimbursed) can be arranged according to participant preference.

ADEPT-2 is a Randomised Control Trial (RCT) for autistic adults, comparing Guided Self-Help with NHS support for depression.

Depression is a common mental health issue, related to lower quality of life. Research indicates that autistic people are more likely to experience depression than non-autistic people. 

Effective treatment for depression includes a talking therapy called low intensity Cognitive Behavioural Therapy (CBT). This form of low intensity therapy is based on supporting the person receiving therapy to work through evidence-based information. This is called Guided Self-Help which has been shown to be useful in non-autistic adults, but it is not known whether it would also be useful for autistic adults.

The main goal of the ADEPT-2 study is to find out whether Guided Self-Help is helpful in reducing depression experienced by autistic adults. 

The ADEPT-2 study also aims to determine whether Guided Self-Help would have a good cost-benefit for the NHS. In addition, the ADEPT-2 study aims to find out whether Guided Self-Help received by an autistic adult has impact on their family carers or supporters. 

To take part you must:

  • Be aged 18 and over
  • Have received a diagnosis of autism spectrum disorder from a healthcare professional(s)
  • Experience low mood or depression
  • Be able to complete forms with questions either online or on paper
  • Be able to give informed consent to take part 

Additional information:

If you decide to take part in the study, you will be randomly selected to receive either Guided Self-Help or NHS support for depression. 

Guided Self-Help involves using a booklet, as well as attending 9 individual meetings with a coach to support use of the booklet. These meetings will be online. If you prefer to meet in person, the study team would be happy to discuss whether that would be possible.   

NHS support for depression might include talking therapy, medication, self-coping strategies, and access to support groups. 

The study will last for 52 weeks. Taking part will involve completing questionnaires at the start of the study, as well as 16 weeks, 32 weeks and 52 weeks later. You will be able to claim a £10 gift voucher for completing every set of questionnaires in the study. There will also be the option to be interviewed about your experience of the study at the end of the study. 

Further information about the ADEPT-2 study can be found here.

Bipolar and Psychosis 

We are trying to understand why some people experience problems with their mental health. The purpose of this study is to collect information and samples for genetic, biological, psychological and clinical research. This will allow us to look for genes and other factors which make some people more likely than others to become ill.

We hope the study will improve understanding of these conditions and help find better treatments in the future.

We are looking to recruit from: 

Early Intervention Services:

  • Over 16-years-old 
  • Lived experience of psychosis

Mother & Baby Unit:

  • Over 18-years-old

With each participant we hope to complete a basic assessment (demographic information, details about the participant’s personal and family history of neurodevelopmental and neuropsychiatric disorders, and questions about medications, physical illness and lifestyle) and take a blood/saliva sample (if possible).

This study aims to understand if some cases of psychosis are caused by immune system problems in some people.

The immune system normally controls our ability to fight infection, but if the immune system goes wrong it may cause diseases called ‘autoimmune’ diseases.

It is possible to diagnose some of these immune diseases using blood tests, and treatments are available if a disease is found.

To be involved in this study you will be asked to give a blood sample.

The appointment may take up to one hour of your time.

You will receive £10 for the time you have spent taking part in the study.

If, from the blood test, we find that you test positive for a disease of the immune system, the study team will contact your clinical team, who, in turn, will contact you with potential treatment options.

To take part in the study you must be:

  • Aged between 18-70 years old
  • Experiencing some symptoms of psychosis

Obsessive Compulsive Disorder (OCD)

This study is a Randomized Controlled Trial (RCT) of Troriluzole, alongside anti-depressant treatment for Obsessive Compulsive Disorder (OCD).  

The main goal is to understand the effects of Troriluzole on OCD symptoms.

Troriluzole has been considered to show benefit for people affected by the symptoms of OCD (an investigational drug for OCD at this point). 

People affected by the symptoms of OCD have been shown to have high levels of Glutamate. Troriluzole might be beneficial in reducing these levels of Glutamate, which cause OCD.

This is a 12-week study.

Those taking part will need to attend Kingshill Research Centre (Swindon) on seven occasions throughout the study period. 

Visits to Kingshill Research Centre will involve the following:

  • Physical health observations and assessments 
  • Questionnaire-based assessment measures

To take part in the OCD study, you must:

  • Be 18-65 years-old
  • Diagnosed or had symptoms of OCD for a year
  • Be currently taking Selective Serotonin Reuptake Inhibitors (SSRIs) for an adequate duration and dose, but with little beneficial response
  • Be able to read, write and understand English in order to consent to take part (those with cognitive impairments will be excluded from taking part)
