This trial is looking at a drug called BAL101553 for advanced cancer. The trial is for people who have one of the following cancers and it has got worse or come back despite having other treatment

Bowel cancer
Stomach cancer
Cancer where the stomach joins the food pipe (gastro oesophageal junction cancer)
Non small cell lung cancer
Ovarian or primary peritoneal cancer
Pancreatic cancer
A type of breast cancer called triple negative breast cancer

Cells reproduce by dividing into 2. Before cells can divide, they create something called microtubules. These help the cells to separate. BAL101553 is a new drug that can stop cells dividing by damaging the microtubules. It is called a microtubule inhibitor. If cancer cells can’t split into 2, then the cancer can’t grow.

This is the first time BAL101553 has been tested in people. The aims of the trial are to

Find the highest safe dose of BAL101553
Learn more about what happens to the drug in your body
See if it helps people with advanced cancers

Trial design

This trial will recruit 64 people. Everybody taking part has BAL101553 through a drip into a vein. It takes about 2 hours each time.

The trial is in 2 parts. The first part recruited 24 people with different types of advanced cancer Open a glossary item .

The first patients taking part had a low dose of BAL101553. If they didn't have any serious side effects, the next patients had a higher dose. And so on, until they found the best dose to give. This is called a dose escalation study and means the researchers find the highest dose they can safely give.

The researchers need 40 people to join the second part of the trial. This is called dose expansion and means the researchers can learn more about how BAL101553 works and any side effects it causes. This part of the trial is randomised. If you join this part, you are put into 1 of 2 groups by a computer. Neither you nor your doctor can decide which group you are in.

20 people have the highest safe dose of BAL101553 found in the first part of the trial
20 people have half (50%) of this dose

You have BAL101553 once a week for 3 weeks, followed by a week without treatment. Each 4 week period is called a cycle of treatment.

Everyone has at least 2 cycles of treatment. If you don’t have bad side effects, you can carry on having the treatment until your cancer gets worse.

During the trial, the researchers take a number of blood samples to learn more about what happens to BAL101553 in your body. This is called pharmacokinetics Open a glossary item .

They will get a sample of your cancer that was removed when you had surgery or a biopsy Open a glossary item in the past. They may ask you to have another biopsy when you join the trial and after 3 weeks of treatment.

They also use these samples to look for substances called biomarkers Open a glossary item that may help them understand more about how the drug works and how it affects your tumour.

The trial team will ask some people to have extra MRI scans. This is to look at the effect BAL101553 has on the blood vessels growing in and around the cancer. You don't have to take part in this study if you don't want to. You can still take part in the main trial.

Hospital visits

You see the trial team and have some tests before you start treatment. The tests include

Physical examination
Heart trace (ECG )
Blood and urine tests
Chest X-ray
CT scan or MRI scan

You go to hospital once a week during the first 2 cycles of treatment. You see the doctors and have blood tests each time. You also have more ECGs.

On 1 occasion, you have a number of blood tests after your treatment. You will spend most of the day at hospital. You may have to stay in overnight. The other hospital visits will be between 4 and 8 hours each.

You have a CT or MRI scan after 2 cycles of treatment. If you carry on having BAL101553 for longer, you then go to hospital 3 times in each 4 week cycle. You have a CT or MRI scan every 8 weeks.

When you finish the treatment, you go back to see the trial team within a week. You have more blood tests and you may have another scan.
