Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
This is a study within Minderoo 5G: A Next Generation AGile Genomically Guided Glioma Modular Platform for proof-of-concept molecular hypothesis testing in patients with high grade malignant brain tumours.
5G-EMERALD is a Bayesian multi-centre, multi-arm, open-label, adaptive, seamless Phase 1 trial of amivantamab for patients with high grade malignant brain tumours.
5G-EMERALD will recruit patients with glioblastoma (GBM) into one molecularly-defined biomarker arm of patients who have tumours that harbour:
• EGFR amplification (high copy number)
The above mentioned arm, within Phase 1, will have robust GO/ADAPT decision points, reviewed by the Safety Review Committee (SRC) to allow for both agility and clear direction for next steps. A 2-stage Bayesian adaptive design will be performed to assess preliminary efficacy.
In the Phase 1b of this study a biomarker defined arm will be opened, initially in the relapsed GBM setting, enrolling 12 patients onto each arm. These patients will be treated with amivantamab. Amivantamab will be administered intravenously (IV) weekly for the first 4 weeks, then every 2 weeks thereafter until disease progression or unacceptable toxicity.

Please, refer to section 4.1 of CTFG guidance "Recommendations related to contraception and pregnancy testing in clinical trials" and to section 9.6 of the Master Protocol for further details.
Note: If the childbearing potential changes after start of the study (eg, participant of childbearing potential who is not heterosexually active becomes active, premenarchal participant experiences menarche) the participant must begin birth control, as described above.

If the participant is vasectomized, they must still use a condom (with or without spermicide) for prevention of passage of exposure through ejaculation, but their partner is not required to use contraception.
