The advantages of pembrolizumab for non-small cell lung cancer notably outweigh disadvantages in comparison with docetaxel or pemetrexed.
Pembrolizumab (trade name: Keytruda), the monoclonal antibody, has been available for the treatment of locally advanced or metastatic non-small cell lung cancer (NSCLC) in adults whose tumors express the T-cell receptor ligand PD-L1 and who have received a prior chemotherapy regimen. The German Institute for Quality and Efficiency in Health Care (IQWiG) examined in a dossier assessment whether the drug offers an added benefit over the appropriate comparator therapy also for these patients.
‘There is considerable added benefit of pembrolizumab in lung cancer patients for whom further chemotherapy (with docetaxel or pemetrexed) or nivolumab is an option.’
The findings revealed that there is an indication of considerable
added benefit of pembrolizumab for patients for whom further
chemotherapy (with docetaxel or pemetrexed) or nivolumab is an option.
For patients for whom these treatments are no longer indicated, however,
an added benefit is not proven. No data for one of two research questions
The Federal Joint Committee (G-BA) distinguished two groups of patients: patients for whom further chemotherapy with docetaxel or pemetrexed or treatment with nivolumab is an option and patients for whom this is not the case. For the first group, data from the KEYNOTE 010 study, which compared pembrolizumab with docetaxel, were available.
To assess an added benefit for the second group, the new drug would have had to be compared with best supportive care, i.e. care optimized for the individual patient to alleviate symptoms and improve quality of life. Since no such study data were available, there was no hint of an added benefit for this research question.
Advantages in mortality, morbidity and some side effects

This was offset by hints of considerably greater harm in immune-related side effects. In the overall assessment, these did not raise doubts about the positive effects, however. In summary, there is therefore an indication of considerable added benefit of pembrolizumab in comparison with the appropriate comparator therapy for this research question.

The dossier assessment is part of the early benefit assessment according to the Act on the Reform of the Market for Medicinal Products (AMNOG) supervised by the G-BA. After publication of the dossier assessment, the G-BA conducts a commenting procedure and makes a final decision on the extent of the added benefit.
