The Role of Regulator-Imposed Post-Approval Studies in Health Technology Assessments for Conditionally Approved Drugs.

BACKGROUND: The European Medicines Agency (EMA) aims to resolve uncertainties associated with conditionally approved drugs by imposing post-approval studies. Results from these studies may be relevant for health technology assessment (HTA) organizations. This study investigated the role of regulator-imposed post-approval studies within HTA. METHODS: For all conditionally approved drugs up to December 2018, regulator-imposed post-approval studies were identified from EMA's public assessment reports. The availability for and inclusion of study results in relative effectiveness (re)assessments were analyzed for 4 European HTA organizations: NICE (National Institute for Health and Care Excellence, England/Wales), HAS (Haute Autorité de Santé, France), ZIN (Zorginstituut Nederland, the Netherlands) and the European Network for Health Technology Assessment (EUnetHTA, Europe). When study results became available between an HTA organization's initial assessment and reassessment, it was evaluated whether and how they affected the assessment and its outcome. RESULTS: For 36 conditionally approved drugs, 98 post-approval studies were imposed. In total, 81 initial relative effectiveness assessments (REAs) and 13 reassessments were available, with numbers of drugs (re)assessed varying greatly between jurisdictions. Study results were available for 16 initial REAs (20%) and included in 14 (88%), and available for 10 reassessments (77%) and included in all (100%). Five reassessments had an outcome different from the initial REA, with 4 (2 positive and 2 negative changes) relating directly to the new study results. Reassessments often cited the inability of post-approval studies to resolve the concerns reported in the initial REA. CONCLUSION: Results from regulator-imposed post-approval studies for conditionally approved drugs were not often used in REAs by HTA organizations, because they were often not yet available at the time of initial assessment and because reassessments were scarce. When available, results from post-approval studies were almost always used within HTA, and they have led to changes in conclusions about drugs' relative effectiveness. Post-approval studies can be relevant within HTA but the current lack of alignment between regulators and HTA organizations limits their potential.

Access to oxytocin and misoprostol for management of postpartum haemorrhage in Kenya, Uganda and Zambia: a cross-sectional assessment of availability, prices and affordability.

OBJECTIVE: To assess access (availability and affordability) to oxytocin and misoprostol at health facilities in Kenya, Uganda and Zambia to improve prevention and management of postpartum haemorrhage (PPH). DESIGN: The assessment was undertaken using data from Health Action International (HAI) research on sexual and reproductive health commodities based on a cross-sectional design adapted from the standardised WHO/HAI methodology. SETTING: Data were collected from 376 health facilities in in Kenya, Uganda and Zambia in July and August 2017. OUTCOME MEASURES: Availability was calculated as mean percentage of sampled medicine outlets where medicine was found on the day of data collection. Medicine prices were compared with international reference prices (IRP) and expressed as median price ratios. Affordability was calculated using number of days required to pay for a standard treatment based on the daily income of the lowest paid government worker. RESULTS: Availability of either oxytocin or misoprostol at health facilities was high; 81% in Kenya, 82% in Uganda and 76% in Zambia. Oxytocin was more available than misoprostol, and it was most available in the public sector in the three countries. Availability of misoprostol was highest in the public sector in Uganda (88%). Oxytocin and misoprostol were purchased by patients at prices above IRP, but both medicines cost less than a day's wages and were therefore affordable. Availability of misoprostol was poor in rural settings where it would be more preferred due to lack of trained personnel and cold storage facilities required for oxytocin. CONCLUSION: Availability and affordability of either oxytocin or misoprostol at health facilities met the WHO benchmark of 80%. However, countries with limited resources should explore mechanisms to optimise management of PPH by improving access to misoprostol especially in rural areas.

Application of Managed Entry Agreements for Innovative Therapies in Different Settings and Combinations: A Feasibility Analysis.

The reimbursement of expensive, innovative therapies poses a challenge to healthcare systems. This study investigated the feasibility of managed entry agreements (MEAs) for innovative therapies in different settings and combinations. First, a systematic literature review included studies describing used or conceptual agreements between payers and manufacturers (i.e., MEAs). Identical and similar MEAs were clustered and data were extracted on their benefits and limitations. A feasibility assessment was performed for each individual MEA based on how it could be applied (financial/outcome-based), on what level (individual patients/target population), in which payment setting (centralized pricing and reimbursement authority yes/no), for what type of therapies (one-time/chronic), within what payment structures, and whether combinations with other MEAs were feasible. The literature search ultimately included 82 papers describing 117 MEAs. After clustering, 15 unique MEAs remained, each describing one or multiple similar agreements. Four of those entailed payment structures, while eleven entailed agreements between payers and manufacturers regarding price, usage, and/or evidence generation. The feasibility assessment indicated that most agreements could be applied throughout the different settings that were assessed and could be applied in different payment structures and in combination with multiple other agreements. The potential to combine multiple agreements leads to a multitude of different reimbursement mechanisms that may manage the price, usage, payment structure, and additional conditions for an innovative therapy. This overview of the feasibility of combinations of MEAs can help decision-makers construct a reimbursement mechanism most suited to their preferences, the type of therapy under evaluation, and the applicable healthcare system.

Towards equitable access to medicines for the rural poor: analyses of insurance claims reveal rural pharmacy initiative triggers price competition in Kyrgyzstan.

BACKGROUND: A rural pharmacy initiative (RPI) designed to increase access to medicines in rural Kyrgyzstan created a network of 12 pharmacies using a revolving drug fund mechanism in 12 villages where no pharmacies previously existed. The objective of this study was to determine if the establishment of the RPI resulted in the unforeseen benefit of triggering medicine price competition in pre-existing (non-RPI) private pharmacies located in the region. METHODS: We conducted descriptive and multivariate analyses on medicine insurance claims data from Kyrgyzstan's Mandatory Health Insurance Fund for the Jumgal District of Naryn Province from October 2003 to December 2007. We compared average quarterly medicine prices in competitor pharmacies before and after the introduction of the rural pharmacy initiative in October 2004 to determine the RPI impact on price competition. RESULTS: Descriptive analyses suggest competitors reacted to RPI prices for 21 of 30 (70%) medicines. Competitor medicine prices from the quarter before RPI introduction to the end of the study period decreased for 17 of 30 (57%) medicines, increased for 4 of 30 (13%) medicines, and remained unchanged for 9 of 30 (30%) medicines. Among the 9 competitor medicines with unchanged prices, five initially decreased in price but later reverted back to baseline prices. Multivariate analyses on 19 medicines that met sample size criteria confirm these findings. Fourteen of these 19 (74%) competitor medicines changed significantly in price from the quarter before RPI introduction to the quarter after RPI introduction, with 9 of 19 (47%) decreasing in price and 5 of 19 (26%) increasing in price. CONCLUSIONS: The RPI served as a market driver, spurring competition in medicine prices in competitor pharmacies, even when they were located in different villages. Initiatives designed to increase equitable access to medicines in rural regions of developing and transitional countries should consider the potential to leverage medicine price competition as a means of achieving their goal. Evaluations of interventions to increase rural access to medicines should include impact assessment on both formal and informal pharmaceutical markets.
