What You Need to Know Before You Apply

What is the purpose of this trial?

This trial explores the safety and effectiveness of combining Lazertinib and Amivantamab (Rybrevant) for individuals with advanced non-small cell lung cancer (NSCLC) that has a specific mutation. Researchers aim to determine if this combination can shrink tumors and improve outcomes for patients who have previously tried other therapies. It is suitable for those with NSCLC with EGFR mutations who have experienced progression after treatments like osimertinib or chemotherapy. As a Phase 1 trial, the research focuses on understanding how the treatment works in people, offering participants the opportunity to be among the first to receive this new combination therapy.

Will I have to stop taking my current medications?

The trial information does not specify if you need to stop taking your current medications. However, you should discuss your current medications with the study team to ensure they don't interfere with the trial treatments.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that combining Lazertinib and Amivantamab is generally safe. Patients who received this combination usually tolerated it well, with manageable side effects. One study found that this combination was more effective than Lazertinib alone for certain lung cancers, and adding Amivantamab did not significantly increase serious side effects.

The FDA has already approved Amivantamab for some lung cancers, supporting its safety. Common side effects include skin reactions and infusion-related reactions, which are usually mild and manageable.

Earlier studies have also shown Lazertinib alone to be safe. The most common side effects were mild, such as rash and changes in liver enzyme levels, and could be managed with supportive care.

Overall, both treatments appear well-tolerated according to available data. Participating in clinical trials can further clarify their safety when used together. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about these treatments for non-small cell lung cancer (NSCLC) because they offer a fresh approach compared to standard therapies like chemotherapy and first- or second-generation EGFR inhibitors. Amivantamab and Lazertinib, used individually or in combination, target specific mutations in the EGFR gene, which are often responsible for cancer growth. This targeted mechanism of action is different from traditional treatments, which don't specifically target these mutations. Moreover, the combination therapy aims to address resistance issues seen with current treatments, potentially offering more effective and longer-lasting results for patients with specific genetic profiles.

What evidence suggests that this trial's treatments could be effective for non-small cell lung cancer?

Research has shown that using Lazertinib and Amivantamab together, as studied in several arms of this trial, may help treat non-small cell lung cancer (NSCLC) with specific genetic changes known as EGFR mutations. Studies have found that this combination can extend patient survival compared to the current standard treatment, osimertinib. It also helps prevent the cancer from developing resistance, a common issue with other therapies. Additionally, Amivantamab alone, studied in a separate arm of this trial, has proven effective for certain EGFR mutations, suggesting it could be beneficial on its own. Overall, this combination treatment offers hope for patients with specific genetic types of NSCLC. ^{2 5 6 7 8}

What Are the Treatments Tested in This Trial?

Interventions

• Amivantamab
• Carboplatin
• Lazertinib
• Pemetrexed

Trial Overview The trial is testing Lazertinib alone or combined with Amivantamab in NSCLC patients. It aims to find the safest dose when used together and assess how well they work against tumors with certain EGFR mutations. Some will also receive standard chemotherapy drugs Carboplatin and Pemetrexed.

How Is the Trial Designed?

Group I: Phase 1b (expansion) Cohort F: Amivantamab Monotherapy Experimental Treatment 1 Intervention

Participants will receive Amivantamab monotherapy once weekly (QW) for 4 weeks, then every 2 weeks thereafter. Cohort F will seek to validate the IHC-based biomarker strategy, previously identified in Cohort D, by characterizing the activity of JNJ-61186372 monotherapy (Cohort F) in biomarker-positive participants with osimertinib-relapsed, but chemotherapy-naïve, EGFR Exon19del or L858R mutated NSCLC.

Group II: Phase 1b (expansion) Cohort E: Lazertinib and Amivantamab Experimental Treatment 2 Interventions

Participants will receive at the RP2CD of Lazertinib orally QD and Amivantamab, every 7 days for the first 28 days cycle and every 2 weeks thereafter. Cohort E will seek to validate the immunohistochemical (IHC)-based biomarker strategy, by characterizing the activity of Amivantamab and Lazertinib combination in biomarker-positive participants with osimertinib-relapsed, but chemotherapy-naïve, EGFR Exon19del or L858R mutated NSCLC. In addition, Cohort E will seek to collect prospective data to confirm that prophylactic anticoagulation safely and effectively decreases the incidence of VTE events for patients treated with the combination of Amivantamab and Lazertinib, using Cohort F as reference.

Group III: Phase 1b (expansion) Cohort D: Lazertinib and Amivantamab Experimental Treatment 2 Interventions

Cohort D will seek to validate one or both potential biomarker strategies (next generation sequencing \[NGS\] and Immunohistochemical \[IHC\]), previously identified in Cohort E of Study 61186372EDI1001, in participants with osimertinib-relapsed, but chemotherapy-naive, EGFR Exon19del or L858R mutated NSCLC. Participants will receive at the RP2CD of Lazertinib orally QD and Amivantamab, every 7 days for the first 28 days cycle and every 2 weeks thereafter.

Group IV: Phase 1b (expansion) Cohort C: Lazertinib and Amivantamab Experimental Treatment 2 Interventions

This Cohort C will further characterize the safety, tolerability and preliminary antitumor activity of Lazertinib and JNJ-61186372 combination in participants with uncommon EGFR mutations. Participants will receive at the RP2CD of Lazertinib orally QD and Amivantamab, every 7 days for the first 28 days cycle and every 2 weeks thereafter.

Group V: Phase 1b (expansion) Cohort B: Lazertinib and Amivantamab Experimental Treatment 2 Interventions

This Cohort B will further characterize the safety, tolerability and preliminary antitumor activity of Lazertinib and JNJ-61186372 combination in participants previously treated with advanced or metastatic NSCLC with documented primary EGFR Exon 20ins activating mutation. Participants will receive at the RP2CD of Lazertinib orally QD and Amivantamab, every 7 days for the first 28 days cycle and every 2 weeks thereafter.

Group VI: Phase 1b (expansion) Cohort A: Lazertinib and Amivantamab Experimental Treatment 2 Interventions

This cohort A will further characterize the safety, tolerability, and preliminary antitumor activity of Lazertinib and Amivantamab based combinations within specific NSCLC population "who have progressed after osimertinib and subsequent platinum-based chemotherapy, and platinum-based chemotherapy regimen as the last line of therapy prior to study enrollment. Prior use of first or second generation EGFR TKI is allowed if administered prior to osimertinib. Participants will receive at the RP2CD of Lazertinib orally QD and Amivantamab, every 7 days for the first 28 days cycle and every 2 weeks thereafter.

Group VII: Phase 1b (combination): Lazertinib, Amivantamab and Platinum-doublet Chemotherapy (LACP) Experimental Treatment 4 Interventions

Participants will receive Lazertinib starting dose administered orally once daily (QD) in combination with Amivantamab, and doses of platinum-based chemotherapy (carboplatin and pemetrexed) per standard of care according to local guidance in a 21-day cycle for 4 cycles followed by maintenance with Lazertinib, Amivantamab and pemetrexed until disease progression or unacceptable toxicities.

Group VIII: Phase 1b (combination): Lazertinib and Amivantamab Experimental Treatment 2 Interventions

Participants will receive Lazertinib and Amivantamab, after the safety of RP2D of Lazertinib is confirmed in the Phase 1, in 28-day cycles until documented evidence of disease progression, unacceptable toxicity, noncompliance, or withdrawal of consent, or the investigator decides to discontinue treatment, whichever comes first. This phase will start enrolling participants after the safety of Amivantamab is confirmed in Japanese participants in Study 61186372EDI1001 (NCT02609776).

Group IX: Phase 1 (monotherapy dose escalation): Lazertinib Experimental Treatment 1 Intervention

Participants will receive Lazertinib monotherapy orally once daily (QD) in 21-day cycles until documented evidence of disease progression, unacceptable toxicity, noncompliance, or withdrawal of consent, or the investigator decides to discontinue treatment, whichever comes first. The subsequent doses of Lazertinib will be assigned by the Study Evaluation Team (SET) according to the dose escalation strategy by Bayesian logistic regression model (BLRM).
