Summary
- Pembrolizumab (Keytruda) is indicated for the treatment of various conditions including unresectable or metastatic melanoma, non-small cell lung cancer (NSCLC), head and neck squamous cell carcinoma (HNSCC), renal cell carcinoma (RCC), and others. It can be used as a single agent or in combination with other therapies.
- A total of 105 studies were reviewed to gather information about pembrolizumab's safety and effectiveness across different indications.
- Compared to chemotherapy alone, immune checkpoint inhibitors like pembrolizumab generally improved overall survival and progression-free survival in patients with advanced NSCLC. PD-L1 expression greater than or equal to 1% was found to be a significant predictor of improved outcomes.
- When combined with chemotherapy, pembrolizumab showed superior efficacy compared to its use as monotherapy for advanced NSCLC patients who have a PD-L1 Tumor Proportion Score greater than or equal to 50%.
- For metastatic melanoma treatment, pembrolizumab, along with other immune checkpoint inhibitors, demonstrated significant survival benefits. However, combining nivolumab and ipilimumab could potentially offer better overall survival but may lead to higher incidences of treatment-related adverse events.
- The risk profile associated with using pembrolizumab varied across studies; it appeared that factors such as the level of PD-L1 expression, histological subtype, e.g., nonsquamous vs squamous NSCLC, influenced this risk profile significantly.
- Pembrolizumab has been identified as an effective first-line therapy when combined with chemotherapy for treating advanced NSLC, irrespective of their levels on PD-L1 expressions, especially those suffering from non-squamous carcinomas.
- In cases where metastatic melanoma was diagnosed, different immune checkpoint inhibitors displayed varying degrees of efficacies and safety profiles. Pembrolizumab was generally well-tolerated and effective, especially in patients with higher PD-L1 expression.
- The combination of pembrolizumab with other agents has demonstrated significant efficacy across various cancer types, particularly in specific patient subgroups defined by PD-L1 expression and histological subtype. This represents a shift towards more personalized and effective cancer therapies.
- The comparative risk of treatment-related adverse events (TRAEs), particularly with combination therapies, necessitates careful patient selection and monitoring. Further research into optimal combination strategies remains critical to enhancing outcomes while managing adverse effects effectively.
