Primary Risk Drivers
Below is a snapshot of domains that materially influence the MARA Rating.
Clinical effectiveness
The evidence indicates that olaparib significantly extends progression-free survival and overall survival compared to placebo, particularly in patients with a BRCA mutation who have undergone two or more courses of platinum-based chemotherapy. The SOLO2 trial data, which is now mature, supports this conclusion, demonstrating a clear clinical advantage over standard surveillance.
Cost effectiveness
The cost-effectiveness estimates for olaparib are within what NICE considers acceptable for Healthcare resources, particularly when considering the commercial arrangement that provides a discount. The committee concluded that the ICER was within the range considered cost-effective, supporting its recommendation for routine use.
Quality of life
Patient experts reported that olaparib ‘massively improves quality of life’ and allows patients to ‘live an amazing life.’ This suggests strong quality-of-life gains, supported by the evidence that maintenance treatment helps extend the time before cancer progression, which is crucial for patient well-being.
Supporting Domains
Safety and Adverse Effects
Olaparib has been described as having manageable side effects, with clinical experts indicating that the tolerability is very good. The evidence suggests that adverse events are mostly mild to moderate, which supports a very good safety profile compared to existing therapies.
Comparator Selection
The clinical trials, particularly the SOLO2 trial, compared olaparib against placebo, which is an appropriate comparator for assessing its effectiveness in the specified patient population. However, there are some limitations regarding the generalizability of the trial population to the broader Healthcare population.
Patient Population and Subgroups
The trial population in the SOLO2 study is broadly generalizable to the Healthcare population, particularly for patients with a BRCA mutation who have undergone two or more courses of platinum-based chemotherapy. However, there are some concerns about the representativeness of the baseline characteristics.
Care Pathway Integration
Olaparib can be integrated into existing care pathways with minor adjustments, as it is already a standard treatment option for patients who have undergone platinum-based chemotherapy. The oral administration of the drug also facilitates its integration into home care settings.
Resource Use and Cost Implications
The budget impact of olaparib is manageable and aligned with Healthcare planning, particularly given the commercial arrangement that provides a discount. The committee noted that the overall resource implications are justifiable in light of the treatment benefits.
Evidence Quality and Robustness
The evidence base for olaparib includes robust data from the SOLO2 trial, which is a well-designed Phase III RCT. While there are some methodological concerns, the overall quality of the evidence is strong and supports the conclusions drawn.
Uncertainty, Sensitivity, and Broader Impacts
While there is some uncertainty regarding the long-term outcomes and the generalizability of trial data, the context of high unmet need and the positive societal impacts of extending remission periods mitigate these concerns. The committee found the overall context supportive of the treatment’s use.
