EM2 Economic IMPACT of Compassionate Use of Medicines

e18840 Background: The economic impact of clinical trials in the perspective of trial sites has been already investigated. Instead, there is no evidence on the economic net benefit of compassionate use programs for medicines (CUP). This research aims to fill the information gap, investigating the economic consequences of 8 CUP in Italy carried out from May 2015 to December 2020 in the hospitals’ perspective. These programs concern five cancer medicines (alectinib, atezolizumab, cobimetinib, polatuzumab vedotin, trastuzumab emtansine TDM-1), for a total of 8 programs. Methods: Economic net benefit includes avoided costs for standard of care (SoC) the patient would have received if he/she has not joined the CUP and costs not covered by the pharmaceutical industry and sustained by the hospital hosting CUP. The latter include costs of adverse event (only severe sides effects generating hospitalisation and ascribed to medicines used in CUP), combination therapies and diagnostic procedures not covered by the sponsor. SoC costing relied on publicly available estimation. Adverse events and diagnostic procedures were retrieved from the CUP and monetized using the relevant fee for episode. Results: 1635 cancer patients were treated in eight CUPs. The SoC mean cost per patient ranges from €13355 to €28098 for all cancer drugs. The total cost of the SoC ranges from €21.8 - €45.9 million. The mean cost per patient covered by hospitals hosting CUP was equal to €2732 for cancer drugs, with a total cost of €4.5 million. The net economic benefit ranges from €17.4 million to €41.5 million for cancer treatments. Conclusions: Despite its limitations this paper illustrates for the first time the net economic impact of CUP in oncology patients in the perspective of payers. Additional evaluations are ongoing to better understand the overall effects of CUP implementation, i.e. the economic value of the comparative benefit profile of medicines used in CUP versus the SoC, including potential effects on indirect costs.
