A trial of MK-7648A for non small lung cancer (KEYVIBE 007)
Please note - this trial is no longer recruiting patients. We hope to add results when they are available.
Cancer type:
Status:
Phase:
This trial is looking at a drug called MK-7648A for non small cell lung cancer.
It is open to people:
- with
non small cell lung cancer 
that has spread (advanced cancer ) - and who haven’t had treatment for their advanced cancer
More about this trial
Doctors can treat advanced non small cell lung cancer (NSCLC) with:
- chemotherapy
immunotherapy - or a combination of both
The chemotherapy doctors can use include:
- carboplatin
- cisplatin
- pemetrexed
MK-7648A is a combination of pembrolizumab and vibostolimab.
Pembrolizumab is an immunotherapy that doctors can use to treat NSCLC. Pembrolizumab works by blocking a protein called PD-1. By blocking PD-1 this helps the find and attack the cancer.
Vibostolimab (MK-7648) is also an immunotherapy. It works by blocking a that affects how well work against cancer. T cells are part of the immune system. By blocking this receptor, T cells are better able to attack cancer cells. Vibostolimab is not yet had approval for doctors to use.
Researchers think that MK-7648A with chemotherapy might work better than pembrolizumab with chemotherapy.
In this trial, half the people will have MK-7648A and chemotherapy. The other half will have pembrolizumab and chemotherapy.
The aims of the trial are to find out:
- how well MK-7648A in combination with chemotherapy works
- more about the side effects
- how this combination affects
quality of life
Who can enter
The following bullet points are a summary of the entry conditions for this trial. Talk to your doctor or the trial team if you are unsure about any of these. They will be able to advise you.

You may be able to join this trial if all of the following apply. You:
- have non small lung cancer (NSCLC) that has spread to another part of the body (stage 4)
- have an area of cancer that the doctor can measure on a
scan - have a piece of cancer tissue (
biopsy ) that the trial team can access. If this isn’t available you are willing to have a fresh biopsy taken. - are able to look after yourself but might not be able to do heavy physical work (performance status 0 or 1)

Who can’t take part
Cancer related
You cannot join this trial if any of these apply. You:
- have already had
systemic treatment for your NSCLC that has spread - are able to have certain targeted drugs to treat your cancer. Or the cancer cells have certain
genes . Your doctor will know about this. - have cancer spread to the brain, spinal cord or the tissue surrounding them. You might be able to join if you have had treatment for this, it is stable and you haven’t taken steroids for at least 2 weeks before starting trial treatment.
- have had radiotherapy to the lung within 6 months of starting treatment and the dose was more than 30
Gray (Gy) . Your doctor will know the dose. - have radiotherapy within 2 weeks of starting treatment. Or have had lung inflammation caused by radiotherapy.
- still have ongoing side effects of radiotherapy
- have had another cancer that had got worse or needed treatment in the past 3 years. You can join if you have had successfully treated
non melanoma skin cancer or a carcinoma in situ (CIS). This is apart from CIS of the bladder. - have taken an experimental drug or used a device as part of a clinical trial within the 4 weeks before starting treatment in this trial
Medical conditions
You cannot join this trial if any of these apply. You:
- have a disease or illness that affects how well your
immune system works - are taking medication that affects how well your immune system works within the week of starting trial treatment. This is apart from a low dose of steroids. Your doctor will know what the dose is.
- have an
autoimmune disease that needed treatment in the past 2 years. This is apart from treatment that replaces what the body would make, such as insulin for diabetes or thyroxine for a thyroid problem. - had inflammation of the lungs not caused by an infection and are taking steroids for it. Or you have this type of lung inflammation whether or not you are taking steroids.
- have HIV, hepatitis B, active hepatitis C or any other active infection that needs treatment
- have had certain
targeted cancer drugs or immunotherapy drugs. Your doctor will know whether you have had any of these. - have had a stem cell or bone marrow transplant from a donor (
allogeneic transplant ) - have had an
organ transplant - have not fully recovered from having major surgery
- have any other medical condition, mental health problem or social situation that could affect you taking part in the trial
Other
You cannot join this trial if any of these apply. You:
- are allergic or very sensitive to any of the treatments or their ingredients
- have had a
live vaccine within 30 days of starting treatment. The COVID-19 vaccine and some seasonal flu vaccines are not live vaccines. - are pregnant or breastfeeding
Pemetrexed chemotherapy
You cannot join this trial if you are to have pemetrexed and any of these apply. You:
- are not able to stop taking aspirin or any other non steroidal anti inflammatory drug (
NSAID ). This is apart from a low dose of aspirin for a short period of time. Your doctor will know about this. - are not able to or not willing to take folic acid or vitamin B12 supplements
Trial design
This is an international phase 3 trial. The team need 700 people worldwide to take part with 20 people from the UK.
It is a randomised trial. A computer puts you into 1 of 2 treatment groups. Neither you nor your doctor can choose which group you are in. The 2 groups are:
- MK-7648A and chemotherapy
- pembrolizumab and chemotherapy
Neither you nor your doctor will know if you are having MK-7648A or pembrolizumab. But your doctor will be able to find out if this is necessary.
Which chemotherapy you have depends on whether you have a squamous cell type of NSCLC or a non squamous cell type of NSCLC. Your doctor will explain which is best for you.
Squamous cell NSCLC
You have one of the following chemotherapy treatments:
Non squamous cell NSCLC
You have one of the following chemotherapy treatments:
You have MK-7648A, pembrolizumab and the chemotherapy as a drip into a vein. You have treatment in periods of 3 weeks. Each 3 weeks is a .
You have all the following once during each cycle of treatment:
- MK-7648A
- pembrolizumab
- carboplatin
- cisplatin
- paclitaxel
You have nab paclitaxel once a week every week during the cycle of treatment.
You have treatment for about 2 years as long as it is helping and the side effects aren’t too bad.
Quality of life
You fill in questionnaires:
- before starting treatment
- during treatment
- at the finish of treatment
- after treatment
The questions ask about:
- your general health
- side effects and how they affect your daily living
- what you can do
These are quality of life questionnaires.
Samples for research
The team ask for a piece of tissue from a previous tissue sample (). If you haven’t had a previous biopsy or it isn’t available the team will ask for a fresh biopsy.
You give blood samples during the trial. Where possible the team take these when you give blood as part of your routine care.
Researchers use these samples to:
- look at the
genes in the cancer cells - look for
biomarkers that might show how well treatment is working - develop and improve tests for people with NSCLC
Hospital visits
You see the doctor for tests before taking part. These include:
- a
physical examination - blood tests
- urine test
- scans such as a CT scan, an MRI scan or bone scan. Your doctor will tell you which scans you are to have.
- heart trace (
ECG )
You see the doctor regularly during treatment. This is to see how you are and for blood tests.
You see the doctor when you finish treatment and then:
- a month later
- then every 3 months
From the start of treatment you have a scan at:
- 6 weeks
- 12 weeks
- 18 weeks
- then every 9 weeks for about 18 months
- then every 12 weeks until you start another treatment or your cancer comes back
Side effects
The trial team monitor you during treatment and afterwards. Contact your advice line or tell your doctor or nurse if any side effects are bad or not getting better.
