Around 1 in 5 people diagnosed with cancer in the UK take part in a clinical trial.
A trial of panobinostat with bortezomib and dexamethasone for myeloma that has come back or is no longer responding to treatment
This trial looked at 3 drugs called bortezomib, panobinostat and dexamethasone for myeloma that had come back or stopped responding to treatment.
More about this trial
If this happens, you may have a drug called bortezomib (also known as Velcade). Bortezomib is a type of biological therapy called a proteasome inhibitor. Proteasomes are in all cells. They help to break down proteins that the cell doesn’t need. If the proteasomes are blocked, the proteins build up in the cell. The cell then dies.
Bortezomib was already used on its own to treat myeloma that had come back after chemotherapy. People taking part in this trial had it with a steroid called dexamethasone. Some people also had a drug called panobinostat.
Panobinostat (also known as LBH589) is a drug that blocks
The aims of this trial were to
- See if adding panobinostat to bortezomib and dexamethasone helped people with myeloma that had come back or stopped responding to treatment
- Learn more about the side effects of this drug combination
Summary of results
The trial team found that panobinostat did help people whose myeloma had stopped responding to treatment or had come back afterwards.
- 387 people had panobinostat, bortezomib and dexamethasone
- 381 had a dummy drug (
placebo), bortezomib and dexamethasone
The overall number of people whose myeloma responded to treatment was
- 235 for those who had panobinostat
- 208 for those who had the dummy drug
The researchers looked at the average length of time the treatment worked for. They found that it was
- Just under a year for people in the panobinostat group
- Just over 8 months for people in the dummy drug group
The most common side effects of panobinostat, bortezomib and dexamethasone were
- Diarrhoea or constipation
- Numbness, tingling or pain in the hands and feet
- Weakness and tiredness
- Feeling or being sick
The trial team concluded that panobinostat was a useful addition to the treatment of people with myeloma that had come back after previous treatment or had stopped responding to treatment.
The trial team are continuing to follow up the people in the trial to find the overall average length of time people live after treatment. When these results become available, we will update this summary.
We have based this summary on information from the team who ran the trial. The information they sent us has been reviewed by independent specialists (
