Independent Market Access and Reimbursement Risk Assessment.

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

Olaparib for maintenance treatment of relapsed, platinum-sensitive ovarian, fallopian tube or peritoneal cancer after 2 or more courses of platinum-based chemotherapy

As of July 2023, MARA’s assessment finds Olaparib’s reimbursement risk concentrated in patient population and subgroups, with quality of life a strength; the current MARA Rating and full rationale are available in the report.

The assessment also weighs evidence quality and robustness: how solid the underlying evidence is on its own terms — trial design, size and endpoints — before any question of price is reached. The strength recorded in quality of life carries weight because that domain asks whether the trial benefit shows up in patients’ daily lives, not only in the clinical endpoints.

What payers will ask

Is the clinical benefit the kind payers reward? — 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.

Does the economic case hold at the expected price? — 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.

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

Does the safety profile hold up for payers? — 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.

Was the drug compared against what payers expect? — 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.

Is the population defined the way payers need it? — 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.

Does the drug fit how care is delivered and paid for? — 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.

Are the wider system costs understood? — 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.

Would the evidence survive payer scrutiny? — 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.

How exposed is the case to uncertainty? — 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.
