Independent Market Access and Reimbursement Risk Assessment.

Crovalimab for treating paroxysmal nocturnal haemoglobinuria in people 12 years and over

As of November 2024, MARA’s assessment finds Crovalimab’s reimbursement risk concentrated in comparator selection and quality of life, with resource use and cost implications 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 resource use and cost implications carries weight because that domain asks what the drug adds to, or removes from, the wider bill beyond its own price — administration, monitoring, hospital time.

What payers will ask

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

Crovalimab has demonstrated clear clinical effectiveness, showing comparable efficacy to eculizumab in clinical trials. Although it has not been directly compared to ravulizumab, indirect comparisons suggest it is likely to be as effective. This evidence supports a significant improvement in outcomes for patients with paroxysmal nocturnal haemoglobinuria.

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

Crovalimab is suggested to have lower costs compared to eculizumab and ravulizumab, which supports its cost-effectiveness. The economic model indicates that it is a viable option under the current pricing arrangements, aligning with common thresholds for cost-effectiveness.

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

The document does not provide specific data on HRQoL improvements associated with crovalimab. While it mentions adverse events related to switching treatments, it lacks detailed evidence on quality of life outcomes, leading to a rating of minimal or mixed impact.

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

The safety profile of crovalimab is acceptable, with some noted adverse events related to immune complex reactions upon switching from other treatments. However, these events are typically transient and manageable, indicating a good overall safety profile.

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

Crovalimab was compared to eculizumab, which is appropriate, but the lack of direct comparison with ravulizumab introduces some limitations. 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 patient population for crovalimab is well-defined, targeting individuals aged 12 years and older with specific clinical criteria. This specificity enhances the generalizability of the findings to the intended patient population.

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

Crovalimab can be integrated into existing treatment pathways with minor adjustments, as it is intended for patients already receiving complement component 5 inhibitors. This suggests a moderate level of integration ease.

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

The economic analysis indicates that crovalimab is likely to have a manageable budget impact, especially given its lower cost compared to existing treatments. This suggests a favorable resource use profile.

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

The evidence supporting crovalimab is derived from clinical trials demonstrating its efficacy and safety. While there are some limitations, the overall quality of evidence is acceptable, supporting its use.

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

The document indicates manageable uncertainty regarding the treatment’s effectiveness and cost-effectiveness. The context of unmet need for patients with paroxysmal nocturnal haemoglobinuria further supports its use.
