A study looking at INCB106385 for advanced solid cancers
Please note - this trial is no longer recruiting patients. We hope to add results when they are available.

Phase:
This study is looking at a drug called INCB106385 by itself or with another drug called retifanlimab (INCMGA00012) for some solid cancers. It is open to people with cancer that has spread to another part of the body or the nearby tissue (advanced cancer).

More about this trial
INCB106385 is an
This is the first time that INCB106385 has been used in cancer patients. But it has been tested in healthy volunteers. Researchers need to find the best dose of INCB106385 for people with cancer to take. The best dose is the dose that helps the most and has the fewest side effects.
Retifanlimab is an immunotherapy called a checkpoint inhibitor. It works by blocking a protein called PD-1. Blocking PD-1 can help the immune system fight cancer.
The researchers know the best dose of retifanlimab to give. This is because a small number of cancer patients have had it.
In this study the team want to know what the best dose of :
- INCB106385 is to have by itself
- INCB106385 is to have with retifanlimab
So in this study some people have INCB106385 by itself and some have it in combination with retifanlimab.
The aims of this study are to find:
- what is the best dose of INCB106385 to have by itself and in combination with retifanlimab
- out more about the side effects of INCB106385 by itself
- out about the side effects of INCB106385 combined with retifanlimab
- how acceptable these treatments are

Trial design
This is a phase 1 study. It is in 2 parts
The team needs a total of up to 306 people to take part:
- 81 people in part 1
- 225 people in part 2
In both parts some people have INCB106385 by itself. And some people have INCB160385 and retifanlimab.
In part 1 the team wants to find the best dose of INCB106385 to have by itself. They also want to find the best dose of INCB106385 when given together with retifanlimab. The best dose is the dose that helps the most and has the fewest side effects.
To find the best dose the first few people have a small dose. If they don’t have any problems then the next few have a higher dose. And so on until the team finds the best dose to give.
Part 2 starts when the team has found the best dose of INCB106385 to have by itself and the best dose of INCB106385 to have with retifanlimab.
What dose you have and whether you have INCB106385 by itself or with retifanlimab depends on when you join the study. Your doctor will tell you about this when you join the study.
INBC106385 is a tablet. You take it with a glass of water. Your doctor will tell you how many to take and when.
Some days you have a blood sample taken at the hospital before you take your dose of INCB106385. On these days you must not eat or drink for at least 2 hours before your visit to hospital. You then take INCB106385 after the blood sample collection and may have more blood taken afterwards. Your doctor will tell you beforehand when these days are.
You have retifanlimab as a drip into a vein. You have it every 4 weeks at the hospital.
You can have treatment for a maximum of 2 years as long as it is helping and the side effects aren’t too bad.
Samples for research
You have a sample of cancer tissue (
The team might ask to take another biopsy during treatment. This biopsy is optional. You don’t have to agree to it.
You give several blood samples during the study. Your doctor will tell you more about when and how often these are.
Researchers use the tissue and blood samples to find out:
- how well treatment is helping
- what happens to INCB106385 and retifanlimab in the body
- how INCB106385 and retifanlimab affects the body
- more about substances (
biomarkers ) that might provide more information about how well treatment is helping
Hospital visits
You see the doctor to have tests before taking part. These tests are:
You see the doctor at regular times during treatment. This is to see how you are, for blood tests and to ask about side effects.
You have a scan every 8 weeks during treatment. After a year this might be every 12 weeks. Your doctor will talk to you about this after a year of treatment.
You see the doctor when you stop treatment. This is to see how you are.
You then see the doctor a month and again 3 months later. This is to see how you are and if you have any side effects.
Side effects
The study 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.
INCB106385 and retifanlimab are immunotherapies. They can affect the immune system. They may cause inflammation in different parts of the body. This can cause serious side effects. They could happen during treatment, or some months after treatment has finished. Rarely, these side effects could be life threatening. Your doctor or nurse can explain what these side effects are, the risk of them happening and what to look out for. If you have any of these side effects tell your doctor or nurse as soon as possible. You should tell them that you are on or have been on an immunotherapy. |
INCB106385 and retifanlimab are new drugs. The combination of these 2 drugs is also new. There might be side effects we don’t know about yet.
INCB106385 has been used in healthy people before. In a completed study of different doses of INCB106385 in healthy volunteers. The side effects that occurred most frequently included:
- headache
- abdominal pain
- dizziness
- feeling sick
- abnormal feeling of pins and needles
- feeling your heart is racing or pounding
- changes to how your kidneys work which can cause passing urine more often or less often, swelling due to too much fluid in the body, muscle cramps and weakness
- lack of energy, feeling weak or poor physical condition
- back pain
- pain in the muscles, bones and nerves of the chest
- constipation or diarrhoea
- loss of appetite
- cough
- dry skin and or itchy skin
Since the start of the study a small number of people have had the combination of INCB106385 and retifanlimab. The side effects that have been reported are:
- a drop in red blood cells causing weakness and tiredness
- lack of energy, weakness or poor physical condition
- an increase of alkaline phosphatase in the blood which might be caused by liver damage or a bone problem
- feeling sick
- high temperature
- pain where the cancer is
A small number of people have had INCB106385 either by itself or in combination with another drug. Side effects reported by at least 2 people are:
- abdominal pain
- lack of energy, feeling weak or poor physical condition
- pain in the back, muscles, bones and nerves of the chest
- constipation or diarrhoea
- feeling or being sick
- loss of appetite
- cough
- change to how well the kidneys work that may cause no symptoms or can cause muscle cramps, weakness, changes to how often you pass urine and or holding water in the body
- dry or itchy skin
Based on animal studies the following side effects of INCB106385 may be possible in humans. They include:
- skin problems such as itching, redness and a rash
- inflammation of the lungs, salivary glands, thyroid, kidneys, pancreas, prostate, colon
- stomach ulcers
- tissue and organs that make hormones (
endocrine ) not working properly - watery eyes
- liver injury
- tiredness (fatigue)
- lack of energy
The most common side effects of retifanlimab are:
- a drop in the red blood cells causing tiredness and feeling weak
- lack of energy, weakness or poor physical condition
- tiredness (fatigue)
- constipation or diarrhoea
- loss of appetite
- high temperature (fever)
- itching
- joint pain
- feeling sick
- urine infection
Your doctor will talk to you about the possible side effects of the treatments before you agree to take part.
