Deferred Registration: Quotient Sciences Code: QSC303709

This clinical trial is an early Phase 1 research study looking at a new investigational medicine. It is being carried out by Quotient Sciences in the UK and is seeking healthy male volunteers aged between 30 and 65 years. Phase 1 trials are the first step in testing a new treatment in humans. Scientists want to find out how safe the medicine is, check for any side effects, and see how the body absorbs and clears it. At this stage, specific scientific details about the medicine are temporarily kept private under standard UK trial rules, known as deferred registration. This is common practice to protect proprietary research while early tests are underway. Full details will be added to the public record once this period ends. Because this study is only for healthy volunteers, it does not aim to treat an illness.

What is this study about?

Before any new medicine can be given to patients living with an illness, scientists must first test it in a small group of healthy volunteers. This is called a Phase 1 clinical trial. These studies help researchers understand how a medicine behaves in the human body, whether it causes side effects, and what dose is safe to use in future research.

This specific study has a 'deferred registration'. In the UK, early Phase 1 trials run by research organisations, such as Quotient Sciences, can legally delay the publication of certain commercial and scientific details. This allows companies to protect new inventions while conducting initial laboratory and safety work. All standard UK regulatory and safety checks still apply, and full details will be made public once the deferral period expires.

Healthy volunteer studies are essential for modern medicine. Without people volunteering to test safety at this early stage, life-saving treatments for conditions like cancer, heart disease, or diabetes could never reach the NHS. By joining, volunteers help lay the foundation for new healthcare discoveries.

Key takeaways

Phase 1 trial focused on testing the safety of a potential new medicine.
Looking for healthy male volunteers aged between 30 and 65 years.
Full scientific details are temporarily confidential under UK deferral rules.
Requires screening, medical checks, and likely a short stay at a specialist clinic.
Participation is voluntary, fully monitored, and does not provide direct health benefits.

Who may be eligible?

This study is open to healthy men aged between 30 and 65 years. Because this is an early safety study, researchers need volunteers whose bodies are functioning normally, so they can clearly see the effects of the new medicine.

Detailed medical criteria have not yet been published due to the deferred status of the trial. However, healthy volunteer studies typically require you to be free from major ongoing medical conditions, have normal blood and urine test results, and have a healthy heart rhythm.

People who take regular prescription medicines, have chronic illnesses, or have a history of drug or alcohol misuse are generally not able to take part. The research team will perform thorough health checks to confirm whether you qualify before you can be enrolled.

Could this study suit you?

Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.

I am a man aged between 30 and 65.
I consider myself to be in good general health.
I do not have long-term medical conditions like diabetes or heart disease.
I am not taking regular prescription medications.
I am able to attend screening appointments and spend time at the research facility.

Answer every question to see your result.

What does participation involve?

Taking part usually begins with a screening visit at a dedicated research clinic. Medical staff will review your medical history and carry out basic tests, such as checking your blood pressure, taking blood and urine samples, and running a heart trace (ECG). If you are eligible, you will receive the study medicine, usually either as a tablet, liquid, or injection. Phase 1 trials often require an overnight stay or a stay of several days at the clinic so the medical team can monitor you closely. Staff will take regular blood samples over set times to measure how the medicine moves through your system. After leaving the clinic, you will attend one or more follow-up visits to confirm you are completely well.

Potential risks and benefits

Because you are joining as a healthy volunteer, there is no direct medical benefit to your own health, although volunteers often receive compensation for their time and travel. As with any new medicine, there are risks of unexpected side effects, allergic reactions, or minor discomfort from tests like blood sampling. Your safety is protected by constant medical supervision from experienced doctors and nurses. Joining is entirely your choice, and you are free to leave the trial at any time without giving a reason.

Common questions

Why are some details about the trial hidden?

Under UK research rules, early Phase 1 trials can temporarily keep scientific formulas private to protect commercial research. The full details will be published once this deferral period ends.

Will I be paid for taking part?

Phase 1 trials involving healthy volunteers usually offer financial payment to cover your time, travel expenses, and any inconvenience.

Is this trial treating a specific disease?

No. This study is purely to test the basic safety and behaviour of a medicine in healthy people, not to treat an active illness.

Can women join this trial?

No. This particular study is only enrolling men aged between 30 and 65. Other studies at the clinic may accept women.

What happens if I change my mind after starting?

You can leave the study at any point. You do not need to give an explanation, and your normal healthcare will not be affected.
