Objectives While there is wide support for patient engagement in health technology assessment, determining what constitutes meaningful (as opposed to tokenistic) engagement is complex. This paper explores reviewer and payer perceptions of what constitutes meaningful patient engagement in the Pan-Canadian Oncology Drug Review process. Methods Qualitative interview study comprising 24 semi-structured telephone interviews. A qualitative descriptive approach, employing the technique of constant comparison, was used to produce a thematic analysis. Results Submissions from patient advocacy groups were seen as meaningful when they provided information unavailable from other sources. This included information not collected in clinical trials, information relevant to clinical trade-offs and information about aspects of lived experience such as geographic differences and patient and carer priorities. In contrast, patient submissions that relied on emotional appeals or lacked transparency about their own methods were seen as detracting from the meaningfulness of patient engagement by conflating health technology assessment with other functions of patient advocacy groups such as fundraising or public awareness campaigns, and by failing to provide credible information relevant to deliberations. Conclusions This study suggests that misalignment of stakeholder expectations remains an issue even for a well-regarded health technology assessment process that has promoted patient engagement since its inception. Support for the technical capacity of patient groups to participate in health technology assessment is necessary but not sufficient to address this issue fully. There is a fundamental tension between the evidence-based nature of health technology assessment and the experientially oriented culture of patient advocacy. Divergent notions of what constitutes evidence and how it should be used must also be addressed.

The CanREValue Collaboration established the Reassessment & Uptake Working Group to develop a preliminary process to reassess funded cancer drugs in Canada. A simulated exercise was conducted to evaluate the proposed reassessment process using a real-world case. We invited 32 attendees including representatives from Health Canada and Health Technology Assessment (HTA) agencies, along with payers, clinicians, academics, and patient representatives. A case was developed using a real-world study on a publicly funded cancer drug. In facilitated group sessions, participants were asked to deliberate upon the evidence presented in the case to issue reassessment recommendations. Several themes were identified through the deliberation discussions. While the generalizability of real-world evidence (RWE) is perceived as a strength, trust in the RWE depends largely on the source of the real-world data. The attendees suggested several improvements to the proposed reassessment process including evidence requirement for reassessment, recommendation categories, and a priori study protocols. This exercise generated important insights on the evidence required for conducting reassessment and considerations for improvements of the proposed reassessment process. Building upon lessons from this exercise, future work would continue to refine the reassessment process as part of the overall CanREValue framework.

Background The soaring costs of anti‐cancer drugs pose a threat to the sustainability of cancer care. The pricing strategy chosen by manufacturers can impact the costs of oral anti‐cancer drugs during dose modifications, but this issue remains under‐recognized in the literature. In general, with the flat pricing strategy, there is a single fixed price for each tablet regardless of dosage strength, whereas with linear pricing, the price of each tablet increases with its dose. We hypothesize that flat pricing will have increased drug costs compared to linear pricing during dose reductions since the cost remains fixed despite decreased dose requirements. This practice may have significant financial implications considering the high costs, extensive utilization, and frequent occurence of dose reductions with anti‐cancer drugs. Methods Oral anti‐cancer drugs reviewed by the pan‐Canadian Oncology Drug Review program between 2011 and 2018 were identified. The cost per mg and cost per 28‐day cycle were calculated for dose levels −2 to +2. The percent change in cost per mg and cost per cycle during dose modifications from the standard dose were calculated. We conducted Mann‐Whitney U and Fisher‐exact tests to compare the association between drug costs during dose reductions and pricing strategy. Results In this study, 30 oral anti‐cancer drugs for use in 41 indications were analyzed; 44% of drugs used linear pricing and 56% used flat pricing. Dose reductions increased the mean cost per mg for drugs with linear pricing by 14.7% (range: 0%‐50%) at dose level −1 and 17.2% (range: 0%‐50%) at dose level −2 and flat pricing by 60.8% (range: 19%‐100%) at dose level −1 and 99.1% (range: 0%‐300%) at dose level −2. The cost per mg was significantly increased in drugs using flat pricing compared to linear pricing when dose reduction to either level ‐1 ( P = 0.010) or level ‐2 ( P = 0.006) occurred. The mean cost per cycle was decreased for drugs using linear pricing by 20.9% (range: −40% to 0%) at dose level −1 and 48.7% (range: −60% to −25%) at dose level −2 and flat pricing by 0.8% (range −6% to 0%) at dose level −1 and 11.0% (range: −50% to 100%) at dose level −2. The cost per cycle was significantly decreased in drugs with linear pricing compared to flat pricing when the standard dose is reduced to either dose level ‐1 ( P = 0.005) or dose level ‐2 ( P = 0.026). Conclusions Overall, flat pricing had significantly greater costs compared to linear pricing during dose reductions of anti‐cancer drugs. While there is a general expectation that the cost of drugs should decrease with dose reduction, drugs with flat pricing were generally found to have increased cost per mg and no change in the cost per cycle. The resultant increased spending on drug acquisition (despite purchasing...
