Independent Market Access and Reimbursement Risk Assessment.

Gavreto / pralsetinib for treating RET fusion-positive advanced non-small-cell lung cancer

As of August 2022, MARA’s assessment finds Gavreto / pralsetinib’s reimbursement risk concentrated in resource use and cost implications, with care pathway integration a strength; the current MARA Rating and full rationale are available in the report.

The assessment also weighs quality of life: whether the trial benefit shows up in patients’ daily lives, not only in the clinical endpoints. The strength recorded in care pathway integration carries weight because that domain asks how the drug fits into the way care is organised today; a treatment that demands new infrastructure or displaces an established pathway faces extra scrutiny.

What payers will ask

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

The clinical evidence for pralsetinib suggests it could be clinically effective, but the benefit is uncertain due to the lack of direct comparisons with standard treatments. The evidence comes from a single-arm study, which limits the ability to draw definitive conclusions about its efficacy compared to existing options.

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

The cost-effectiveness estimates for pralsetinib are uncertain and considered too high for it to be deemed a cost-effective use of Healthcare resources. The committee noted that the maximum acceptable ICER would be at the lower end of the range typically considered acceptable, indicating significant cost concerns.

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

There is no specific data presented on HRQoL improvements associated with pralsetinib. The document indicates that the treatment may help manage symptoms of advanced NSCLC, but without robust evidence, the impact on quality of life remains unclear.

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

Pralsetinib is described as having a manageable safety profile, with adverse events that are consistent with those seen in similar treatments. The document does not indicate any severe safety concerns that would undermine its use.

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

The comparators used in the appraisal were aligned with Healthcare practice, but the company did not compare pralsetinib directly with all relevant standard treatments. This limits the robustness of the comparative effectiveness data.

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

The patient population considered in the trials reflects the intended real-world population for pralsetinib, with appropriate subgroup analyses for untreated and previously treated patients. However, the lack of data for squamous NSCLC is a limitation.

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

Pralsetinib is an oral treatment that offers a clear advantage over intravenous therapies typically administered in hospitals. This suggests a good fit within existing care pathways, although some adjustments may be necessary for RET fusion testing.

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

The document indicates that the cost implications of pralsetinib are significant, and while it may provide some benefits, the overall resource burden raises concerns about its affordability within the Healthcare.

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

The evidence base is primarily derived from a single-arm trial, which raises concerns about its robustness. The quality of the trial was marked down in several areas, indicating potential biases and limitations in the evidence.

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

There are significant uncertainties regarding the clinical effectiveness and cost-effectiveness of pralsetinib, particularly due to the reliance on indirect treatment comparisons and the assumptions made in the economic model.
