Trial Summary

What is the purpose of this trial?

This trial is testing two drugs, Osimertinib and Amivantamab, to treat a specific type of lung cancer. The study focuses on adults whose cancer has certain genetic changes and has either advanced locally or spread. Osimertinib works by stopping cancer cells from growing, while Amivantamab helps the immune system attack these cells. Osimertinib is a standard treatment for non-small cell lung cancer with EGFR mutations, and Amivantamab targets EGFR exon 20 insertion mutations, showing promise in early trials.

Do I need to stop my current medications to join the trial?

The trial protocol does not specify if you must stop taking your current medications. However, you cannot use medications or supplements that are strong inducers of CYP 3A4, and any concurrent anti-cancer treatment requires an adequate washout period before starting the study.

What data supports the idea that Osimertinib + Amivantamab for Lung Cancer is an effective drug?

The available research shows that Amivantamab, when used with other treatments like lazertinib or chemotherapy, has shown positive results in treating non-small cell lung cancer (NSCLC), especially in cases where the cancer has progressed after other treatments. Although specific data on the combination of Osimertinib and Amivantamab is not directly mentioned, both drugs have individually shown effectiveness in treating NSCLC. Amivantamab has been approved for use in the USA for certain types of NSCLC, and Osimertinib is effective against a common mutation that causes resistance to other treatments. This suggests that the combination could be promising for patients with advanced NSCLC. ^{1 2 3 4 5}

What safety data is available for the treatment of Osimertinib and Amivantamab in lung cancer?

Amivantamab (Rybrevant) has been approved for use in non-small cell lung cancer (NSCLC) with EGFR Exon 20 insertion mutations, with safety data indicating it is used after progression on platinum-based chemotherapy. Osimertinib (Tagrisso) is approved for NSCLC with certain mutations, with common adverse effects including leukopenia, lymphopenia, thrombocytopenia, diarrhea, anemia, rash, musculoskeletal pain, nail toxicity, neutropenia, dry skin, stomatitis, fatigue, and cough. The combination of Amivantamab and Lazertinib has shown efficacy in osimertinib-relapsed NSCLC, suggesting ongoing evaluation of safety in combination therapies. ^{2 3 4 6 7}

Is the drug combination of Osimertinib and Amivantamab promising for lung cancer?

Yes, the combination of Osimertinib and Amivantamab is promising for lung cancer. Osimertinib is effective for certain lung cancers with specific mutations, and Amivantamab has shown positive results in treating lung cancer, especially when other treatments have failed. Together, they offer a strong potential for improving outcomes in lung cancer patients. ^{1 2 8 9 10}

Findings from Research

In a study of 240 advanced non-small-cell lung cancer (NSCLC) patients with acquired resistance to EGFR TKIs, 52.9% had the T790M mutation after rebiopsy, highlighting the mutation's prevalence in treatment resistance.

Patients with the T790M mutation who had previously used osimertinib experienced significantly longer post-progression survival (42.6 months) compared to those without osimertinib (18.0 months) or without the mutation (18.8 months), suggesting osimertinib's effectiveness as a standard treatment for T790M-positive NSCLC.

Amivantamab is a bispecific monoclonal antibody that targets both EGFR and MET, specifically developed for treating non-small cell lung cancer (NSCLC) with EGFR Exon 20 insertion mutations.

It received its first approval in the USA on May 21, 2021, for adult patients with advanced NSCLC who have progressed after platinum-based chemotherapy, and is currently in preregistration in multiple countries including the EU and Japan.

Amivantamab: First Approval. Syed, YY.[2021]

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.

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 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.

In a retrospective analysis of 32 patients with EGFR T790M-mutant non-small-cell lung cancer, osimertinib showed a 50% objective response rate and a median progression-free survival of 11.3 months, indicating its efficacy in clinical practice.

The median overall survival was 18.3 months, with better outcomes observed in patients without cerebral metastases and those with better performance status, highlighting the importance of these factors in treatment response.

In a study of 62 patients with EGFR-mutated advanced non-small cell lung cancer, the combination of osimertinib and chemotherapy did not significantly improve progression-free survival compared to osimertinib alone, with median PFS of 15.8 months for monotherapy versus 14.6 months for the combination.

The overall response rate was higher in the osimertinib monotherapy group (71.4%) compared to the combination group (53.6%), and the safety profile of the combination treatment was comparable to previously reported data for carboplatin and pemetrexed, indicating it was generally tolerable.
