5G-EMERALD: Amivantamab in Malignant Brain Tumours
United Kingdom12 participantsStarted 2024-10-09
Plain-language summary
The purpose of this clinical trial is to evaluate the safety and tolerability of amivantamab and to determine the preliminary antitumour activity of amivantamab administered at the recommended Phase 2 dose (RP2D). In the Phase 1b of this study a biomarker defined arm will be opened, initially in the relapsed GMB setting, enrolling 12 patients. These patients will be treated with amivantamab monotherapy. Amivantamab will be administered intravenously (IV) weekly for the first 4 weeks, then every 2 weeks thereafter until disease progression or unacceptable toxicity. The first dose will be given as a split infusion, 350 mg IV over 4 hours on cycle 1 day 1 and 1400 mg IV over 6 hours on cycle 1 day 2. Subsequent infusions are given at a dose of 1750 mg IV over 2-5 hours in cycle 1 and between 2-3 hours from cycle 2 onwards if the first dose was well-tolerated with no significant toxicity.
Progression to Phase 2 is dependent on emergent data and funding.

Inclusion criteria
. Patients with histologically confirmed advanced WHO Stage IV glioblastoma (per fourth edition 2016). Per the new 2021 fifth edition of WHO Classification of Tumours of the Central Nervous System, this will include:
. Patients for Phase 1 will need to have consented to the Minderoo Precision Brain Tumour Programme and have available whole genome, and transcriptome data available.
. Patients for the relapsed cohorts will be eligible at first relapse following completion of optimal surgery, and Stupp based adjuvant chemo-radiotherapy (or equivalent). They will need to have measurable disease per Response Assessment in Neuro-Oncology (RANO) or evaluable disease.
Exclusion criteria
. 16 years or over.
. Life expectancy of at least 12 weeks.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

. World Health Organisation (WHO) performance status of 0-1.
. Neurologically stable (e.g., without a progression of neurological symptoms or requiring escalating doses of systemic steroid therapy within the last week).
. Written (signed or dated) informed consent and be capable of co-operating with treatment and follow up.
0. Haematological and biochemical indices within the ranges shown below. These measurements must be performed within one week prior to the first dose of either IMP:
1. Female patients with reproductive potential must have a negative serum, or urine, pregnancy test at screening and within 72 hours of the first dose of study treatment and must agree to further serum or urine pregnancy tests during the study.
2. A participant must be either of the following: a. not of childbearing potential, b. of child-bearing potential and practicing true abstinence during the entire period of the study, including up to 6 months after the last dose of the study treatment is given, or c. of childbearing potential and practicing 2 methods of contraception, including 1 highly effective user independent method and a second method, to avoid impregnating a partner or becoming pregnant, respectively. A participant must agree to continue contraception throughout the study, and for at least 6 months after the last dose of study treatment.
