Trial Outcomes & Findings for Premedication to Reduce Amivantamab Associated Infusion Related Reactions (NCT NCT05663866)

NCT ID: NCT05663866

Last Updated: 2025-11-12

Results Overview

Percentage of participants with IRRs at Cycle 1 Day 1 was reported. IRRs were defined as IRR events with onset time within 24 hours of the start of the first amivantamab infusion and prior to the start of amivantamab infusion on Cycle 1 Day 2. IRR included chills, dyspnea, flushing, nausea, chest discomfort, vomiting, tachycardia, hypotension, and fever. IRRs that occurred on Cycle 1 Day 2 pre-infusion were considered under Cycle 1 Day 1.

Measure
Cohort A: Dexamethasone 4 Milligrams (mg)
Participants were administered with oral dexamethasone 4 mg tablet as a prophylactic treatment twice a day (8 mg total daily dose) on Day -1 (Cycle 1) prior to combination therapy of lazertinib 240 mg oral tablets and IV infusion of amivantamab 1050 mg (for participants less than \[\<\] 80 kilograms \[kg\]) or 1400 mg (for participants greater than or equal to \[\>=\] 80 kg) on Cycle 1 Day 1 until disease progression or withdrawal from study. Each cycle was of 28 days.
Cohort A2: Dexamethasone 8 mg
Participants were administered with oral dexamethasone 8 mg tablet as a prophylactic treatment twice a day (16 mg total daily dose) on Day -2 and -1 (Cycle 1) and 8 mg approximately one hour prior to IV infusion of amivantamab 1050 mg (for participants \<80 kg) or 1400 mg (for participants \>=80 kg) on Cycle 1 Day 1 until disease progression or withdrawal from study. Each cycle was of 28 days.

Participants were administered with oral montelukast 10 mg tablet as a prophylactic treatment once daily in the morning on Days - 4, -3, -2, -1, and Cycle 1 Day 1 prior to combination therapy of lazertinib 240 mg oral tablets and IV infusion of amivantamab 1050 mg (for participants \<80 kg) or 1400 mg (for participants \>=80 kg) on Cycle 1 Day 1 until disease progression or withdrawal from study. Each cycle was of 28 days.
Cohort C: Methotrexate 25 mg
Participants were administered with a single dose of methotrexate 25 mg subcutaneous injection as a prophylactic treatment on any day between Days -7 and Day -3 (Cycle 1) prior to combination therapy of lazertinib 240 mg oral tablets and IV infusion of amivantamab 1050 mg (for participants \<80 kg) or 1400 mg (for participants \>=80 kg) on Cycle 1 Day 1 until disease progression or withdrawal from study.

PRIMARY outcome

Timeframe: Cycle 1 Day 1 (each cycle of 28 days)

Population: The per protocol analysis set included all participants who had received all prophylaxis treatment based on schedule and had received the administration of amivantamab and lazertinib on Cycle 1 Day 1.

Percentage of participants with IRRs at Cycle 1 Day 1 was reported. IRRs were defined as IRR events with onset time within 24 hours of the start of the first amivantamab infusion and prior to the start of amivantamab infusion on Cycle 1 Day 2. IRR included chills, dyspnea, flushing, nausea, chest discomfort, vomiting, tachycardia, hypotension, and fever. IRRs that occurred on Cycle 1 Day 2 pre-infusion were considered under Cycle 1 Day 1.
