Plain English Summary
Background and study aims
Kirsten rat sarcoma virus (KRAS), neuroblastoma rat sarcoma virus (NRAS), & v-Raf murine sarcoma viral oncogene homolog B1 (BRAF) wild-type metastatic colorectal cancer are subtypes of colorectal cancers (CRCs), defined by absence of specific genetic alterations*. If cancer cannot be completely removed with surgery &/or has spread to other organs, treatment includes chemotherapy along with lab-made proteins that can bind to specific targets in body, however CRC can return after treatment.
*Changes in genes that control the way cells grow & multiply.
Amivantamab is a bispecific antibody** that binds to the epidermal growth factor receptor (EGFR) & mesenchymal-epithelial transition (MET) proteins & turn them off, which may kill or slow down the growth of cancer cells.
**Protein that helps protect the body against foreign matter.
In this study researchers want to learn if amivantamab in combination with chemotherapy (FOLFIRI) works at slowing the progression of cancer and increase duration of life compared to using cetuximab or bevacizumab with the same chemotherapy, if cancer has returned after initial chemotherapy.
Who can participate?
Participants 18 years or older with colorectal cancer who have previously received chemotherapy.
What does the study involve?
Study will consist of:
• Screening Period (up to 28 days)
• Treatment Period (until EOT/30 days after stopping study treatment): Eligible participants will be randomly (by chance) assigned to either of 2 groups:
o Arm 1: Amivantamab as injection under skin and FOLFIRI injected directly into a vein using a needle.
o Arm 2: Cetuximab or bevacizumab and FOLFIRI injected directly into a vein using a needle.
• Follow-up Phase (until end of study)- Participants will be followed-up to monitor their health.
Participants will undergo study assessments such as blood and urine tests & questionnaires. Blood samples will be taken at multiple timepoints to understand how body responds to study treatment.
All side effects will be recorded till study ends (approximately 2 years 9 months).
What are the possible benefits and risks of participating?
There is no established benefit to participants of this study. Based on scientific theory, taking amivantamab may improve colorectal cancer. However, this cannot be guaranteed because amivantamab is still under investigation as a treatment and it is not known whether amivantamab will work.
Participants may experience some benefit from participation in the study that is not due to receiving study drug, but due to regular visits and assessments monitoring overall health. Participation may help other people with colorectal cancer in the future.
Participants may have side effects from the drugs or procedures used in this study that may be mild to severe and even life-threatening, and they can vary from person to person. The most common, known risks are getting symptoms such as skin toxicities, respiratory toxicities, allergic and
anaphylactic-like reactions (severe life-threatening allergic reaction) and hypersensitivity (exaggerated immune response to a drug or other substance), infusion reactions, blood-related toxicities, scarring of lung tissue/inflammation of lung tissue, surgery and wound healing
complications, inflammation of the mucosa (membranes that line mouth and gastrointestinal tract), nausea, or vomiting, gastric system related toxicities, excessive loss of blood, cardiovascular system related toxicities, neurological toxicities, excessive protein in urine (due to bevacizumab) and
diarrhea (due to irinotecan) after getting the study drug. There are other, less frequent risks. The participant information sheet and informed consent form, which will be signed by every participant agreeing to participate in the study, includes a detailed section outlining the known risks to participating in the study.
Not all possible side effects and risks related to amivantamab are known at this moment. During the study, the sponsor may learn new information about amivantamab. The study doctor will tell participants as soon as possible about any new information that might make them change their mind about being in the study, such as new risks.
To minimise the risk associated with taking part in the study, participants are frequently reviewed for any side effects and other medical events. Participants are educated to report any such events to their study doctor who will provide appropriate medical care. Any serious side effects that are
reported to the sponsor are thoroughly reviewed by a specialist drug safety team.
There are no costs to participants to be in the study. The sponsor will pay for the study drug and tests that are part of the study. The participant will receive reasonable reimbursement for study-related costs (e.g., travel/parking costs).

| Scientific title | A randomized, open-label phase 3 study of amivantamab + FOLFIRI versus cetuximab/bevacizumab + FOLFIRI in participants with KRAS/NRAS and BRAF wildtype recurrent, unresectable or metastatic colorectal cancer who have received prior chemotherapy |
| Study acronym | OrigAMI-3 |
| Study hypothesis | Main objectives 1. To compare how long a participant is disease-free (progression-free survival) and the length of time until a participant dies (overall survival) in participants treated with amivantamab + FOLFIRI versus those treated with cetuximab or bevacizumab + FOLFIRI. Secondary objectives 1. To further assess additional measures of clinical benefit 2. To assess safety 3. To assess disease symptoms, treatment tolerability (how well participants are managing any treatment related side effects), and how the treatment is affecting their overall quality of life. |
