Primary Risk Drivers
Below is a snapshot of domains that materially influence the MARA Rating.
Clinical effectiveness
Nintedanib shows a clear clinical advantage by significantly slowing the decline of lung function in patients with idiopathic pulmonary fibrosis (IPF) with an FVC above 80% predicted, as evidenced by the results from the phase 3 INPULSIS trials and the TOMORROW trial. The pooled results indicate a reduction in FVC decline of 128.4 ml per year compared to placebo, with long-term efficacy maintained over time.
Cost effectiveness
The cost-effectiveness estimates for nintedanib are within acceptable thresholds for Healthcare resources, with an ICER below £20,000 per QALY gained. This indicates a strong economic value proposition for the treatment, especially when considering the commercial arrangement that provides a discount.
Quality of life
While specific HRQoL data is not extensively detailed, the committee noted that nintedanib’s ability to slow disease progression is likely to positively impact patients’ quality of life, as it addresses significant symptoms associated with IPF. The evidence suggests moderate improvements in HRQoL, although direct measures were not highlighted.
Supporting Domains
Safety and Adverse Effects
Nintedanib has an acceptable safety profile, with adverse events being manageable and primarily mild to moderate. The committee acknowledged that while there are concerns regarding tolerability, the overall safety data supports its use in the indicated population.
Comparator Selection
The treatment was compared against placebo in pivotal trials, which is appropriate given the lack of other active treatments for patients with an FVC above 80% predicted. This selection aligns with current clinical practice and guidelines.
Patient Population and Subgroups
The trials included a representative population of patients with IPF, specifically those with an FVC above 80% predicted. While there are some limitations in subgroup analyses, the core population is well covered.
Care Pathway Integration
Nintedanib can be integrated into existing care pathways with minor adjustments, as it is recommended for a specific patient population that currently has limited treatment options. The committee noted that it fits well within the current treatment landscape for IPF.
Resource Use and Cost Implications
The budget impact of nintedanib is manageable, and the treatment is expected to provide significant benefits relative to its costs. The committee concluded that the resource implications are justifiable given the expected health outcomes.
Evidence Quality and Robustness
The evidence base is strong, supported by multiple phase 3 RCTs and long-term extension studies. While there are some concerns regarding the systematic review methodology, the overall robustness of the evidence is sufficient for decision-making.
Uncertainty, Sensitivity, and Broader Impacts
While there are some uncertainties regarding the extrapolation of survival data, the committee noted that the treatment addresses a significant unmet need in a population with limited options. The context supports a favorable assessment despite some residual uncertainties.
