Around 1 in 5 people diagnosed with cancer in the UK take part in a clinical trial.
A trial of sonidegib for advanced cancer that has got worse despite other treatment
This trial looked at a drug called sonidegib (also known as LDE225) for solid tumours that have spread to another part of the body. A solid tumour is any type of cancer apart from
Sonidegib is a type of biological therapy. It is a cancer growth blocker. It stops the signals that cancer cells use to divide and grow.
This was the first time that sonidegib was given to patients. The people taking part had different types of advanced cancer that had got worse despite having other treatments. The aims of the trial were to
- Find the best dose of sonidegib to give
- Learn more about the side effects and what happens to sonidegib in your body
- See how well it works for advanced cancer
Summary of results
The trial team found the best dose of sonidegib to give. They also found that it helped some people with a type of skin cancer called basal cell cancer (BCC) and some people with a type of brain tumour called medulloblastoma.
103 people with advanced cancer took part in the trial. The first few people had a low dose of sonidegib. As they didn’t have bad side effects, the next few people had a higher dose. And so on, until the research team found the best dose to give. This type of trial is called a dose escalation study.
The trial team looked at how well sonidegib worked to keep the cancer under control. They have the results for 99 people and found that
- In 1 person with basal cell skin cancer (BCC) the cancer went away completely
- In 8 people with BCC or medulloblastoma the cancer got a bit smaller
- In 24 people the cancer stayed the same
- In 66 people the cancer continued to grow
Sonidegib did have some side effects but they were usually mild to moderate. The side effects included muscle spasms and pain, stomach problems, liver problems, tiredness, changes in taste and hair loss.
The research team concluded that sonidegib was safe to give. They found that it was a useful treatment for some people with BCC and medulloblastoma and they recommend that it is looked at further in other trials.
