J&J's Lung Cancer Combo Cuts Death Risk 25% Over Tagrisso

Johnson & Johnson's innovative combination therapy involving Rybrevant and Lazcluze has shown promising results in treating non-small cell lung cancer (NSCLC), outperforming AstraZeneca's Tagrisso in terms of overall survival. In a recent phase III MARIPOSA study, the Rybrevant-Lazcluze regimen was tested as a first-line treatment for patients with advanced or metastatic NSCLC characterized by specific EGFR mutations. The results have indicated a significant reduction in the risk of death from any cause by 25% when compared to the use of Tagrisso.

The study's median follow-up period was 37.8 months, during which this combination therapy demonstrated a highly statistically significant improvement in overall survival. While the median overall survival (OS) for patients treated with Tagrisso was recorded at 36.7 months, the median OS for those receiving Rybrevant and Lazcluze had not yet been reached. This suggests that the survival benefits of the Rybrevant-Lazcluze combo extend beyond the current data collection period, implying a potential long-term advantage for patients.

Additionally, the MARIPOSA study achieved several secondary objectives, highlighting the Rybrevant regimen's superiority in intracranial progression-free survival, intracranial duration of response, and overall intracranial response rate. Patients also experienced a significant delay in symptom progression with this treatment.

The Rybrevant and Lazcluze combination received approval in August 2024, with the FDA allowing its use as a first-line treatment for a specific subgroup of NSCLC patients harboring EGFR mutations. This approval marked a significant advancement for patients with locally advanced or metastatic disease, providing an alternative to the widely used Tagrisso.

Johnson & Johnson has announced its intention to share these updated results with health authorities globally, aiming to expand the availability of this treatment. However, analysts from Guggenheim Partners have pointed out that a critical next step for the company involves securing FDA approval for a subcutaneous formulation of Rybrevant. This could potentially offer patients a more convenient and tolerable treatment option.

The company's initial attempt to gain approval for the subcutaneous version was rejected by the FDA in December 2024 due to concerns related to the manufacturing process, though no issues were found with the drug formulation or its supporting data. If successful in obtaining approval, the subcutaneous option could enhance patient experience and support Johnson & Johnson's ambitions for the Rybrevant franchise to achieve annual peak sales exceeding $5 billion.

As Johnson & Johnson continues to refine and expand its cancer treatment offerings, the Rybrevant and Lazcluze combination represents a significant advancement in the fight against NSCLC, promising improved survival rates and better quality of life for patients affected by this challenging condition.
