Five-Year Follow-Up Shows Improved Survival in NSCLC Patients
Libtayo® Plus Chemotherapy: Five-Year Survival Results
Recent findings from exploratory analyses at a major cancer conference indicate that Libtayo® (cemiplimab) combined with chemotherapy shows a significant enhancement in both overall survival rates and effectiveness for patients battling advanced non-small cell lung cancer (NSCLC). This combination has produced an astonishing five-year survival rate of 19.4%, more than double the 8.8% observed with chemotherapy alone.
Long-Term Survival Analysis
In-depth five-year analyses revealed consistent efficacy across different tumor types, especially within squamous NSCLC patients, who enjoyed a median overall survival of 22.3 months. These encouraging statistics come from Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN), which presented compelling data at a world-renowned lung cancer conference.
Daniela Baramidze, M.D.'s Insight
Dr. Ana Baramidze, who leads clinical research at Todua Clinic, highlighted the long-term benefits of introducing Libtayo to chemotherapy for advanced NSCLC patients. The study emphasizes the sustained survival improvements for various patient profiles, showcasing Libtayo's flexibility as both a standalone treatment and in conjunction with chemotherapy.
Phase 3 EMPOWER-Lung 3 Trial Results
The Phase 3 EMPOWER-Lung 3 trial, which involved 466 patients with no EGFR, ALK, or ROS1 mutations, was designed to evaluate the combined treatment of Libtayo and platinum-based chemotherapy against chemotherapy alone. Results from this comprehensive study continue to support the advantages of the combination therapy, reinforcing Libtayo's role in enhancing patient outcomes.
Five-Year Efficacy Observations
Findings presented at this year's conference further validate Libtayo's efficacy:
- Median Overall Survival: 21.1 months for Libtayo plus chemotherapy compared to 12.9 months for chemotherapy alone, equating to a 34% reduced risk of death.
- Median Progression-Free Survival: 8.2 months with the combination versus 5.5 months for chemotherapy alone, marking a 42% decrease in disease progression risk.
- Objective Response Rate: Libtayo plus chemotherapy achieved a 43.6% response rate, in contrast to 22.1% for chemotherapy alone, including a complete response rate of 6.4% versus 0%.
- Duration of Response: 16.4 months for Libtayo combination versus 7.3 months for chemotherapy alone.
Subgroup Analysis
Subgroup analyses revealed further survival advantages among NSCLC patients treated with Libtayo. Specific findings include:
- 22.3-month median overall survival in patients with squamous histology compared to 13.8 months.
- 19.4-month median overall survival in patients with non-squamous histology.
- 24.0-month median overall survival for patients with PD-L1 expression of at least 1%.
Safety Profile
Data from the five-year mark indicated that the safety profile for Libtayo remains consistent with past reports. Among patients receiving Libtayo combined with chemotherapy, 96.5% experienced adverse events, primarily of lower severity. Common side effects reported include anemia, alopecia, and gastrointestinal issues, with 30% of serious adverse events leading to treatment discontinuation in the Libtayo group versus significantly less in the chemotherapy arm.
