Independent Market Access and Reimbursement Risk Assessment.

Built by former payers, HTA reviewers, and Industry Experts. 

Guselkumab for previously treated moderately to severely active Crohn's disease

As of August 2025, MARA’s assessment finds Guselkumab’s reimbursement risk concentrated in comparator selection, with cost effectiveness a strength; the current MARA Rating and full rationale are available in the report.

The assessment also weighs safety and adverse effects: what harms arrive alongside the benefit, which payers set against the gains before funding a treatment. The strength recorded in cost effectiveness carries weight because that domain asks whether the price asked stands in a defensible relationship to the benefit delivered — the core of most European reimbursement decisions.

What payers will ask

Is the clinical benefit the kind payers reward? — Clinical effectiveness

Clinical trial evidence shows that guselkumab increases the likelihood of disease remission and endoscopic response compared with placebo. Although it has not been directly compared with risankizumab or vedolizumab, indirect comparisons suggest that it is likely to work as well as these alternatives, indicating a clear clinical advantage.

Does the economic case hold at the expected price? — Cost effectiveness

A cost comparison indicates that the costs for guselkumab are similar to or lower than those for risankizumab and vedolizumab, suggesting that it is clearly cost-effective under common thresholds.

Is there quality-of-life evidence payers weigh? — Quality of life

While specific HRQoL data is not detailed in the document, the overall benefits of guselkumab in achieving disease remission and endoscopic response imply potential improvements in quality of life for patients with Crohn’s disease. However, the evidence is moderate and not explicitly quantified.

Does the safety profile hold up for payers? — Safety and Adverse Effects

The document does not provide detailed safety data, but it implies that guselkumab is a viable option after other treatments have failed, suggesting an acceptable safety profile. However, specific adverse effects are not discussed, leading to some concerns.

Was the drug compared against what payers expect? — Comparator Selection

Guselkumab has not been directly compared in clinical trials with risankizumab or vedolizumab, which are key comparators. The reliance on indirect comparisons raises concerns about the robustness of the evidence.

Is the population defined the way payers need it? — Patient Population and Subgroups

The population for which guselkumab is indicated is well-defined, targeting adults with previously treated moderately to severely active Crohn’s disease. The document suggests that it is intended for patients who have not responded to or cannot tolerate other treatments.

Does the drug fit how care is delivered and paid for? — Care Pathway Integration

Guselkumab is positioned as a treatment option within existing care pathways for Crohn’s disease, requiring no significant changes to current practices. The guidance indicates that it should be funded and available within a specified timeframe, facilitating integration.

Are the wider system costs understood? — Resource Use and Cost Implications

The document indicates that guselkumab is to be funded within the NHS and suggests that its cost is manageable compared to alternatives. This implies a notable but justifiable cost burden with proportional benefits.

Would the evidence survive payer scrutiny? — Evidence Quality and Robustness

The evidence supporting guselkumab includes clinical trial data and indirect comparisons, which provide a reasonable level of robustness. However, the absence of direct head-to-head trials introduces some methodological concerns.

How exposed is the case to uncertainty? — Uncertainty, Sensitivity, and Broader Impacts

While there are some uncertainties regarding the indirect comparisons, the overall context of unmet need for Crohn’s disease treatments and the supportive evidence for guselkumab’s efficacy mitigate these concerns.
