Primary Risk Drivers
Below is a snapshot of domains that materially influence the MARA Rating.
Clinical effectiveness
Somatrogon is reported to be as effective as one preparation of somatropin (Genotropin) for treating growth disturbance caused by growth hormone deficiency. This indicates a clear clinical advantage with significant improvement in primary outcomes compared to the standard of care.
Cost effectiveness
The cost comparison suggests that the costs of somatrogon are similar to those of existing somatropin preparations, indicating it is clearly cost-effective under common thresholds with manageable uncertainty.
Quality of life
While the document does not provide specific HRQoL data, it implies that somatrogon is a suitable treatment option. However, there is no mention of validated tools showing significant improvements in quality of life, leading to a rating of minimal impact.
Supporting Domains
Safety and Adverse Effects
The document does not highlight any significant safety concerns or adverse effects associated with somatrogon, suggesting an acceptable safety profile with manageable adverse events.
Comparator Selection
Somatrogon was compared against somatropin, which is the standard treatment for growth hormone deficiency. This indicates a very good selection of comparators with minor gaps.
Patient Population and Subgroups
The patient population for somatrogon includes children and adolescents aged 3 years and over with growth hormone deficiency, which is a relevant and representative group for the treatment being assessed.
Care Pathway Integration
Somatrogon is a weekly injection compared to daily somatropin, which may simplify administration. This indicates minor adjustments needed for integration into existing care pathways.
Resource Use and Cost Implications
The estimated annual cost for a patient is around £9,500, which is justifiable given the comparable costs to existing treatments and the expected benefits.
Evidence Quality and Robustness
The evidence presented is based on clinical trials showing effectiveness comparable to somatropin, indicating acceptable evidence quality with some methodological concerns.
Uncertainty, Sensitivity, and Broader Impacts
The document indicates a favorable context for somatrogon, with manageable uncertainties regarding its implementation and cost-effectiveness.
