Deferred registration - Quotient Sciences Code: QSC304026

This clinical trial is a Phase 1 study managed by Quotient Sciences in the UK. The research team is looking for healthy men aged between 30 and 65 years to take part. The main purpose of Phase 1 trials is to see how safe a new medicine is and how the human body processes it. Because this research is in its earliest stages, the sponsor has an official 'deferred registration.' This is a standard process that temporarily keeps specific scientific details private to protect new research. The full information will be made public once the deferral period expires. Healthy volunteers in these studies are closely looked after by doctors and nurses in a specialist clinic. Joining the trial is entirely your choice, and you can withdraw at any point.

What is this study about?

Phase 1 clinical trials are the first step in testing potential new medicines in people. Before a new treatment can be given to patients living with an illness, scientists must first make sure it is safe. To do this, researchers invite healthy volunteers to take small doses in a carefully controlled medical clinic. They check how the body absorbs, breaks down, and removes the medicine, and watch out for any unwanted side effects.

This specific study, known by the code QSC304026, is run by Quotient Sciences. You may notice that certain information about the study drug is not listed yet. This trial has what is called a 'deferred registration.' UK regulators allow researchers to keep certain commercial details private for a short time while early testing begins. All scientific details will be added to the public record as soon as the deferral period finishes.

Even though the public record is deferred, the study must still follow strict UK safety and ethics laws. An independent research ethics committee reviews the study plan to protect the rights, safety, and well-being of all volunteers before any tests can begin.

Studies like this are vital for medical progress. Without healthy people stepping forward to test early medicines, scientists would not be able to develop safe, effective treatments for serious diseases in the future.

Key takeaways

  • This is an early-stage Phase 1 trial testing the safety of a potential new medicine.
  • The study is currently recruiting healthy male volunteers aged between 30 and 65.
  • Full scientific details are temporarily withheld under standard UK registry deferral rules.
  • Volunteers will be closely monitored by medical staff in a dedicated research unit.
  • Taking part is voluntary, and participants are free to leave at any stage.

Who may be eligible?

To take part in this trial, you must be a man between the ages of 30 and 65. The trial is only open to healthy volunteers, which means you should not have any serious, long-term health conditions or illnesses.

Because the full scientific details are currently deferred, the complete list of medical rules has not yet been published online. However, healthy volunteer studies usually require you to be a non-smoker (or light smoker), have a healthy body weight, and not be taking regular prescription medications.

Before you can join, the clinic's medical team will carry out standard health checks. These include checking your blood pressure, taking blood and urine samples, and recording your heart rhythm to ensure it is completely safe for you to take part.

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.

  1. I am a male.
  2. I am between 30 and 65 years old.
  3. I consider myself to be in good general health.
  4. I do not have major, long-term medical conditions.
  5. I am willing to undergo routine health checks and stay at a research clinic.
Answer every question to see your result.

What does participation involve?

Taking part in an early-stage trial usually begins with a screening appointment at a specialist clinic. The medical team will explain the study in plain language and answer all your questions. If you agree to take part, they will run general health checks to confirm you are eligible. If accepted, you will likely spend time staying at the clinic or making several day visits. While there, you will receive the study medicine, and doctors will carefully monitor your vital signs, heart rhythm, and take regular blood samples. After the treatment period finishes, you will attend a follow-up appointment or receive a phone call to make sure you remain well. The exact schedule and length of time required will be fully explained by the study team before you sign any agreement.

Potential risks and benefits

Taking part in a Phase 1 study does not offer any direct medical benefit, as you are already healthy. However, your participation helps scientists develop new medicines that could benefit patients in the future. Clinical trials often provide compensation for your time and travel expenses. The potential risks include side effects from the study medicine, which might be mild, such as a headache or tiredness, or occasionally more serious. Minor discomfort from blood tests or clinic stays is also possible. You are never trapped in a clinical trial; you have the legal right to stop and leave the study at any time, for any reason, without it affecting your regular healthcare.

Common questions

What does 'deferred registration' mean?

It means the trial sponsor has official permission to keep specific scientific details private for a limited time to protect their research, before releasing them publicly.

Why is this trial only open to men aged 30 to 65?

Early trials often focus on a specific age and sex group to keep the test results consistent and avoid unnecessary risks before more is known about the medicine.

Will I be paid for taking part?

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

Is the study safe if details are kept private?

Yes. The trial must still be reviewed and approved by an independent UK Research Ethics Committee and the Medicines and Healthcare products Regulatory Agency (MHRA).

What happens if I change my mind during the trial?

You are completely free to leave the trial at any point. The doctors will simply perform a final health check to ensure you are safe and well.
