Trial Summary

What is the purpose of this trial?

The purpose of this study is to assess the efficacy of adding lazertinib to amivantamab, carboplatin, and pemetrexed (LACP/ACP-L dosing strategies) and amivantamab, carboplatin and pemetrexed (ACP) compared with carboplatin and pemetrexed (CP) in participants with locally advanced or metastatic epidermal growth factor receptor (EGFR) Exon 19del or Exon 21 L858R substitution non-small cell lung cancer (NSCLC) after osimertinib failure. The purpose of the extension cohort is to further describe the safety and efficacy for the ACP-L dosing schedule versus ACP with additional data. After completion of the primary analysis, the study may eventually transition to an open-label extension (OLE) or long-term extension (LTE) phase during which participants will have the option to continue their assigned treatment.

Will I have to stop taking my current medications?

The trial requires that you stop taking osimertinib at least 8 days before starting the study treatment. The protocol does not specify if you need to stop other medications, so it's best to discuss this with the trial team.

What data supports the effectiveness of the drug combination Amivantamab, Lazertinib, and Chemotherapy for Non-Small Cell Lung Cancer?

Research shows that Amivantamab combined with chemotherapy (Carboplatin and Pemetrexed) and sometimes Lazertinib has shown antitumor activity in patients with advanced non-small-cell lung cancer, especially those with specific genetic mutations. This combination has been effective in patients who have not responded to other treatments, like osimertinib. ^{1 2 3 4 5}

Is the combination of Amivantamab, Lazertinib, and Chemotherapy safe for humans?

Amivantamab combined with chemotherapy (carboplatin and pemetrexed) has shown safety in early studies for advanced non-small cell lung cancer, and it is approved for certain types of this cancer. However, more data is needed to fully understand the safety of this combination with lazertinib. ^{1 2 4 6 7}

What makes the drug combination of Amivantamab, Lazertinib, and Chemotherapy unique for treating non-small cell lung cancer?

This drug combination is unique because it targets specific mutations in non-small cell lung cancer (NSCLC) that have become resistant to other treatments, like osimertinib. Amivantamab is a bispecific antibody that targets both EGFR and MET mutations, while Lazertinib is a third-generation EGFR inhibitor that can penetrate the brain, making this combination effective even after other treatments have failed. ^{1 2 3 5 8}

Findings from Research

In a phase III trial involving 657 patients with advanced EGFR-mutated non-small-cell lung cancer, both amivantamab-chemotherapy and amivantamab-lazertinib-chemotherapy significantly improved progression-free survival (PFS) compared to standard chemotherapy, with median PFS of 6.3 and 8.3 months versus 4.2 months, respectively.

The combination therapies also showed a higher objective response rate (64% and 63% for amivantamab-chemotherapy and amivantamab-lazertinib-chemotherapy, respectively) compared to chemotherapy (36%), although the amivantamab-lazertinib-chemotherapy regimen had more hematologic adverse events.

In a phase 3 trial involving 308 patients with advanced non-small-cell lung cancer (NSCLC) and EGFR exon 20 insertions, the combination of amivantamab and chemotherapy significantly improved progression-free survival compared to chemotherapy alone, with a median of 11.4 months versus 6.7 months.

The combination therapy also showed a higher response rate, with 73% of patients achieving a complete or partial response compared to 47% in the chemotherapy-only group, indicating that amivantamab enhances the effectiveness of standard chemotherapy in this patient population.

Amivantamab, approved for treating non-small cell lung cancer with specific genetic mutations, works by targeting two pathways: the epithelial growth factor receptor and mesenchymal epithelial transition factor, enhancing the immune response against cancer cells.

Preclinical studies indicate that Amivantamab effectively inhibits cancer cell growth in models with exon20 insertions of the epithelial growth factor receptor, suggesting its potential as a targeted therapy for this specific patient population.

The ongoing CHRYSALIS study shows that the combination of amivantamab, an EGFR-MET bispecific antibody, and lazertinib, a third-generation EGFR TKI, is effective in treating both treatment-naive patients and those who have relapsed after osimertinib.

The MARIPOSA study is a phase 3 trial designed to compare the safety and efficacy of the amivantamab and lazertinib combination therapy against single-agent osimertinib, aiming to improve first-line treatment outcomes for patients with EGFR-mutant non-small-cell lung cancer.

Amivantamab-vmjw has shown a 40% overall response rate in patients with metastatic non-small cell lung cancer (NSCLC) with EGFR exon 20 insertion mutations, based on a phase 1 trial involving 81 participants, indicating its efficacy after platinum-based chemotherapy.

The treatment resulted in a median progression-free survival of 8.3 months and an overall survival of 22.8 months, with an acceptable safety profile, marking it as a significant advancement for patients with limited treatment options.

In a real-life study of 121 patients with advanced non-squamous non-small cell lung cancer, the combination of pembrolizumab and chemotherapy resulted in a median progression-free survival of 9 months and overall survival of 20.6 months, demonstrating its efficacy as a first-line treatment.

The treatment was generally well-tolerated, with manageable side effects; however, 17.5% of patients experienced grade 3-4 adverse events, and there were two treatment-related deaths, indicating the need for careful monitoring during therapy.

In a study of 61 patients with advanced EGFR-mutant NSCLC, amivantamab showed a clinical response rate of 45.2% and a disease control rate of 64.3%, indicating its potential effectiveness beyond just exon 20 insertion mutations.

The combination of amivantamab with osimertinib and concurrent radiation therapy was found to be safe, with no additional toxicities reported, suggesting that this treatment approach could be a viable option for patients.
