  • Research summary

    Research Summary:
    AMG 404 is an antibody that is made by identical immune cells that are all clones of a unique parent cell and works by activating an immune response against cancer. It blocks the activity of a molecule found in our bodies, called PD-1, that prevents immune cells from recognising and attacking cancer cells.
    Animal studies have shown no serious toxic effects of AMG 404.
    This is a first in human study to determine the side effects and best dose of AMG 404 in treating patients with advanced solid tumours in approximately 42 participants across 4 groups of patients (cohorts) in different dose levels-- Cohort 1-240mg; Cohort 2—480mg, Cohort 3-Also 480 mg for confirming the efficacy of this dose and Cohort 4—1050mg to evaluate if this high dose can be given.
    AMG 404 will be administered intravenously every 4 weeks in participants with advanced solid tumours continuing until disease progression, intolerance to study medication, consent withdrawal, or if up to 12 months participant achieves a complete response, and up to 24 months if participant shows partial response or stable disease.
    During the study, the participants will undergo AMG 404 treatment, safety and research evaluation of the study product through their blood and urine samples, archival tumour blocks (fresh biopsy if archival samples are not available) and radiographic scans through CT or MRI (as appropriate).
    Participants who have consented for this study and are above 18 years with advanced solid tumours would be eligible for the study. The study will last for 2.5 years.
    The study will take place in Australia, Brazil, Belgium, Poland, France, UK, USA, Japan and South Korea.
    In the UK, the study will take place at the Sarah Cannon Research Institute, 93, Harley Street, London, W1G 6AD

    3. General Information About the Clinical Study Where and when was the study done?
    • This study took place in Australia, Belgium, Brazil, Canada, Japan, Poland, Singapore, South Korea, Spain, Taiwan, Turkey, the United Kingdom, and the United States.
    • The study began in March 2019 and ended in November 2023.
    • The study was stopped earlier than planned for business strategy reasons. The study was not stopped because of safety reasons.
    Why was the study done?
    • This was a phase 1 study conducted as part of the early process to develop new medicines for humans to treat cancer. Researchers looked at how this medicine works in the body and the effect that it has in the body, including side effects.
    • The main purpose of this study was to find out information about the safety of the study medicine AMG 404 alone and also in combination with other cancer therapies. To do this, researchers looked at:
    - The number of participants who developed medical problems considered significant enough to stop any further increase in the dose of study medicine (called dose-limiting toxicities).
    - The number of participants who developed adverse events at any time after being given their first dose of study medicine. An adverse event is any unwanted medical problem that may or may not have been caused by the study medicine.
    - The number of participants who developed medical problems that the doctor thought could have been caused by the study medicine.
    - Changes in vital signs (eg, blood pressure and heart rate) and clinical laboratory tests (eg, blood and urine tests).
    • The study was stopped early for business strategy reasons. AMG 404 was not given in combination with other cancer therapies in this study as originally planned.

    4. Who Was Included in This Study?
    Who took part in the study?
    This study included 171 participants with advanced solid tumors, including cancers of the digestive system, chest, head, neck, reproductive system, soft tissue, and kidney. 79 participants (46%, or about 46 out of 100) were women and 92 participants (54%, or about 54 out of 100) were men. They ranged in age from 26 to 84 years. 103 participants (60%, or about 60 out of 100) were younger than 65 years old and 68 participants (40%, or about 40 out of 100) were older than 65 years. This study took place at 34 study centers across Australia, Belgium, Brazil, Canada, Japan, Poland, Singapore, South Korea, Spain, Taiwan, Turkey, the United Kingdom, and the United States. The numbers of participants in each country are listed below:
    • Australia: 30
    • Belgium: 20
    • Brazil: 9
    • Canada: 12
    • Japan: 13
    • Poland: 25
    • Singapore: 7
    • South Korea: 10
    • Spain: 4
    • Taiwan: 1
    • Turkey: 1
    • United Kingdom: 9
    • United States: 30
    Participants were examined by a study doctor and chosen to be in the study if they:
    • were 18 years or older
    • had an advanced solid tumor

    5. Which Medicines Were Studied?
    • AMG 404 is a type of medicine called an immunotherapy, which is designed to help the body’s immune system find and destroy cancer cells. AMG 404 blocks a type of protein (called programmed cell death protein 1) on the cell surface. Blocking this protein is thought to help the body’s immune system destroy cancer cells.
    • AMG 404 was given once every 4 weeks by short-term intravenous infusion, where a tube is placed into a blood vessel (usually a vein in the participant’s arm) and the study medicine is given over a short period of time (30 minutes in this study).
    • 3 of the 171 participants did not receive any study medicine and are not included in the side effects or results sections below. The remaining 168 participants received AMG 404.
    • Participants were placed into 1 of 8 groups (called “cohorts”), numbered 1 to 4 and 6 to 9. Other cohorts numbered 5 and 10 to 13 were planned but never opened to participants. Cohorts were selected based on tumor type and were administered doses of AMG 404 as described below:
    - Cohort 1: 3 participants were given low dose AMG 404.
    - Cohort 2: 9 participants were given medium dose AMG 404.
    - Cohort 3: 20 participants were given medium dose AMG 404.
    - Cohort 4: 21 participants were given high dose AMG 404.
    - Cohort 6: 20 participants were given medium dose AMG 404.
    - Cohort 7: 41 participants were given medium dose AMG 404.
    - Cohort 8: 41 participants were given medium dose AMG 404.
    - Cohort 9: 13 participants were given medium dose AMG 404.

    6. What Were the Side Effects?
    What is a side effect?
    All medicines can cause side effects, or unwanted medical problems that may happen when you take a medicine. In this study, doctors reported all the medical problems participants had. Doctors believed some of the problems could have been caused by the study medicine(s). These possible side effects are listed below.

    This section only shows the most often reported side effects considered by the study doctor as related to study medicine. No single clinical study can give a complete picture of the benefits and risks of a medicine. Information about other side effects may be available at the websites listed at the end of this summary.

    7. What Were the Overall Results of the Study?
    • No dose-limiting toxicities were reported in this study.
    • 167 out of 168 participants (99%) had at least 1 adverse event after receiving the first dose of study medicine.
    • 110 out of 168 participants (65%) had at least 1 possible side effect.
    • 1 out of 168 participants (1%) died of a possible side effect (cancer that spread to the spine).
    • More results may be available at the websites listed at the end of this summary.

    8. How Has This Study Helped Participants and Researchers?
    What else is important to know about these results?
    These results are only for this clinical study, which looked at a sample of 171 people with advanced solid tumors. Not all participants in the study had the same results. The results for any single participant could have been better or worse than the results for their group. Other studies may find different results. These results do not explain how a study medicine may work in a single person. Many studies are needed to show the benefits and risks of a medicine that is still being tested. This research may help future participants and families by helping doctors understand more about the study medicine being studied.
