A trial looking at olaparib for small cell lung cancer (STOMP)
Please note - this trial is no longer recruiting patients. We hope to add results when they are available.
This trial is looking at olaparib for people with small cell lung cancer (SCLC) who have already had one other treatment. This trial is supported by Cancer Research UK.
Doctors treat small cell lung cancer with chemotherapy or chemotherapy and radiotherapy (
Olaparib is a type of biological therapy called a PARP inhibitor. It blocks an
In this trial some people will have olaparib and some people will have a dummy drug (placebo).
The aims of this trial are to find out
- If olaparib can be used as maintenance therapy for people with SCLC
- If olaparib can increase the length of time people live
- How safe olaparib is as maintenance therapy for SCLC
Who can enter
You may be able to enter this trial if
- You have small cell lung cancer (SCLC)
- You have had at least 3 cycles of chemotherapy or
chemoradiotherapywith cisplatin, or carboplatin with etoposide
- On a scan, your cancer had shrunk or there was no sign of it after treatment – your doctor can confirm this
- You are well enough to be up and about for at least half the day (performance status 0, 1 or 2)
- Your blood test results are satisfactory
- You are able to swallow tablets
- You are willing to use reliable contraception during treatment and for 3 months afterwards if there is any chance you or your partner could become pregnant

- Your last treatment of radiotherapy was more than 3 weeks ago
- The start of your last cycle of chemotherapy was more than 6 weeks ago
- You still have moderate to severe side effects from your treatment apart from hair loss
- Your cancer has spread to your brain and you have symptoms that aren’t controlled
- You have a non cancerous disease of your lung tissue or the space surrounding the air sacs of your lungs (called interstitial lung disease) – your doctor can confirm this
- You have had another cancer in the past 3 years apart from successfully treated non melanoma skin cancer or
in situ carcinomaof the cervix or breast
- You have problems with your
digestive systemthat could affect how you absorb tablets
- You have had an experimental drug as part of a clinical trial in the past 2 weeks
- You have already had olaparib or another PARP inhibitor – your doctor can confirm this
- You are having certain medications that affect body proteins called CY3P enzymes – your doctor can advise about this
- You have had a heart attack in the past 3 months or have any other medical condition that could affect you taking part in this trial
- You are HIV, hepatitis B or hepatitis C positive
- You have uncontrolled fits (seizures)
- You have
myelodysplastic syndromeor acute myeloid leukaemia (AML) – the trial team will test for these
- You have had major surgery in the past 2 weeks or haven’t recovered from major surgery
- You are allergic to olaparib or its ingredients
- You are pregnant or breastfeeding
This is a phase 2 trial. It will recruit 222 people. It is a randomised trial. The people taking part are put into treatment groups by a computer. Neither you nor your doctor will be able to decide which group you are in. And neither of you will know which group you are in. This is called a double blind trial. The groups are
- People who have 2 olaparib tablets 3 times a day
- People who have 3 olaparib tablets twice a day
- People who have 2 dummy tablets 3 times a day
- People who have 3 dummy tablets twice a day
Olaparib and the dummy drug are tablets. You take them every day for 2 years.
If your cancer comes back during the 2 years, you stop taking the olaparib or dummy drug. Your doctor will talk to you about other treatment that may be available to you.
If you have very bad side effects the doctor can reduce the number of tablets you take.
The trial team will ask you to fill out a questionnaire before you start treatment, every month during treatment and after you finish treatment. The questionnaire will ask about side effects and how you’ve been feeling. This is called a quality of life study.
If you agree to take part in this study, the researchers will ask for 3 extra blood samples during the trial and for a sample of your cancer that was removed when you had surgery or a
You see the doctor to have some tests before taking part in this trial. These tests include
- A physical examination
- Blood tests
- CT scan
- Chest X-ray
During treatment you see the doctor every month for a physical examination and blood tests. You have a chest X-ray at 4 weeks and then every 2 months.
If you stopped treament early due to side effects rather than your cancer getting worse with your permission the trial team would like you to have a CT scan every 2 months.
After treatment your doctor will tell you how often they want to see you.
Olaparib is a new drug and there may be side effects we don’t know about yet. The most common side effects may include
