Clinical trials are research studies that investigate potential new medical treatments and procedures and compare them to the current standard treatments.
Drugs and treatments are usually assessed in three phases before they can be considered as a standard treatment option. Each clinical trial phase is designed to answer a specific set of questions about a new drug or treatment, which means there are strict guidelines about who can participate.
This builds on the findings from Phase I, improving knowledge of the potential side effects of the treatment and the best dose of the treatment to give.
It usually involves up to 100 people and looks at which type of cancer the treatment might work best for. If tumours respond to the treatment (either by slowing down growth or reducing in size), it moves to Phase III.
Many women view taking part in a clinical trial as a very positive experience. Some of the benefits include:
Getting a new treatment before it is widely available.
Being one of the first to benefit if the drug or treatment works.
Receiving additional monitoring and care – you will need to attend regular tests and check-ups.
Helping advance medical knowledge for the benefit of women now and in the future.
Often, clinical trials are randomised, so you will not know whether you are receiving the new or standard treatment. However, research has shown that taking part in a trial can be beneficial, even if you do not have the drug or procedure being tested. This could be because trials involve additional care and monitoring at the hospital.
You also need to consider that new treatments are not always better than standard treatments. The new drug or treatment might not work for you and sometimes there are unexpected side effects.
As trials compare new treatments with standard treatments, you may be selected to receive either the new treatment or the standard treatment. So by agreeing to be in a trial, it does not necessarily mean you will receive the new drug being tested.
Speak to your oncologist, who should be able to tell you about suitable trials in your local treatment centre. If there isn’t a trial, they may be able to give you information about trials in other hospitals, if you are willing and able to travel.
You might want to ask about:
- What trials are you eligible for at your treatment centre?
- If you're willing and able to travel, what is available at another centre?
- What is the aim of the trial?
- What is the evidence that this new treatment might be effective?
- What are the possible risks and benefits of taking part?
- What taking part would involve compared to not taking part
Remember, if you are suitable, it is your decision whether or not to join a clinical trial.

Having discussed the possibilities for treatment with your oncologist, you may want to seek a second opinion, either at your current hospital, or one which is more involved in research and trials. Your Clinical Nurse Specialist (CNS) should be able to advise you on how to get a second opinion.
A drug is given a license by the European Medicines Agency (EMA) or the Medicines and Healthcare products Regulatory Agency (MHRA) in the UK once it is deemed safe to use in a certain group of patients, and has shown to be of some benefit.
Drug manufacturers generally submit applications for licenses once the results of clinical trials are published. This process can take up to a year.
Once a drug is licensed, the National Institute of Health and Care Excellence (NICE) and the Scottish Medicines Consortium will, if asked, assess whether the drug should be used by the NHS.
They look at the clinical and cost effectiveness of the drug. In other words, does the drug in question work better than standard treatments offered (either for all patients, or for a particular group of patients)? Is the price to the NHS acceptable for the amount of benefit seen?
This process can take some considerable time, and countries within the UK may reach different conclusions.
This means it can take up to two years, or more, from results of trials being announced to the drugs being approved for use on the NHS.
