Primary Risk Drivers
Below is a snapshot of domains that materially influence the MARA Rating.
Clinical effectiveness
Cemiplimab has shown promising results in clinical trials, with an objective response rate of 46.1% and median overall survival not reached after 15.7 months. However, it has not been directly compared with best supportive care, and the evidence from indirect comparisons is considered highly uncertain. Therefore, while it meets non-inferiority, there is no clear edge over existing options.
Cost effectiveness
The ICER for cemiplimab compared to best supportive care is estimated at £30,952 per QALY gained, which is within NICE’s acceptable range. Despite uncertainties in clinical effectiveness, the committee concluded that the cost-effectiveness estimates are likely acceptable.
Quality of life
The committee noted that cemiplimab is well tolerated and can lead to substantial benefits for those who respond, including improved quality of life due to reduced tumor burden. However, specific HRQoL data from validated instruments is not detailed in the document.
Supporting Domains
Safety and Adverse Effects
Cemiplimab has a very good safety profile, with most adverse events being mild to moderate, such as fatigue and rashes. Serious autoimmune side effects are manageable, indicating a favorable tolerability compared to existing therapies.
Comparator Selection
The primary comparator is best supportive care, which is appropriate given the patient population. However, the lack of direct comparisons with other treatments limits the robustness of the evidence.
Patient Population and Subgroups
The trial population is moderately representative of the intended patient population, with a median age of 72 years. However, there are concerns about the generalizability of trial results to the older population treated in the Healthcare.
Care Pathway Integration
Cemiplimab can be integrated into existing care pathways with minor adjustments, as it is a monotherapy that does not require significant changes in infrastructure or training.
Resource Use and Cost Implications
The budget impact is manageable, with the potential for cost savings due to the commercial arrangement. The treatment is expected to be resource-efficient given its cost-effectiveness.
Evidence Quality and Robustness
While there are promising results from clinical trials, the evidence base has gaps, particularly due to the lack of direct comparisons and reliance on indirect comparisons, which introduces uncertainty.
Uncertainty, Sensitivity, and Broader Impacts
There is significant uncertainty regarding the clinical effectiveness and survival estimates, particularly due to the differences between trial populations and real-world data. This uncertainty may impact decision-making.
