Around 1 in 5 people diagnosed with cancer in the UK take part in a clinical trial.
A trial of MK-2206 with chemotherapy or erlotinib for advanced cancer
This trial looked at a drug called MK-2206 alongside chemotherapy or erlotinib for solid tumours that have continued to grow despite treatment.
AKT is a protein in cancer cells which tells them to carry on growing even when they have been damaged by treatment. MK-2206 is a treatment which can block the action of AKT. The research team hoped MK-2206 would help stop cancer cells growing.
The aims of this trial were to
- Find the best dose of MK-2206 to use
- See how well MK-2206 works with chemotherapy or erlotinib for advanced cancer
Summary of results
The research team found that MK-2206 was an acceptable treatment and that it did have some effect on cancer cells.
This phase 1 trial recruited 72 people with an advanced solid tumour. They were put into 1 of 3 groups, depending on which treatment option was best for their cancer type.
- 31 people in group 1 had MK-2206 with carboplatin and paclitaxel
- 16 people in group 2 had MK-2206 with docetaxel
- 25 people in group 3 had MK-2206 with erlotinib
Some people had MK-2206 every other day, some once a week and some once every 3 weeks, depending on which option was best for them.
The first few people in each group had the lowest dose of MK-2206. As they didn’t have any serious side effects, the next few people had a higher dose. And so on, until the trial team found the best dose to give. This is called a dose escalation study.
MK-2206 did cause some side effects, but most of them were not classed as serious. The most common side effects were tiredness, feeling or being sick, rash, diarrhoea, loss of appetite, hair loss and a sore mouth.
The research team were able to look at how well the treatment worked for 58 of the people who took part. They found that the cancer
- Went away in 1 person
- Got a bit smaller in 7 people
- Stayed the same in 43 people
- Continued to grow in 7 people
The research team concluded that MK-2206 didn’t cause too many side effects when given with other drugs, and that it did have some effect on cancer cells.
