Costs of radium-223 and the pharmacy preparation 177Lu-PSMA-I&T for metastatic castration-resistant prostate cancer in Dutch hospitals

Field: Medicine (Health Sciences)

The radiopharmaceuticals radium-223 and the pharmacy preparation 177Lu-PSMA-I&T are reimbursed in the Netherlands for metastatic castration-resistant prostate cancer (mCRPC) treatment. Although shown to be life-prolonging in patients with mCRPC, the treatment procedures associated with these radiopharmaceuticals can be challenging for both patients and hospitals. This study investigates the costs of mCRPC treatment in Dutch hospitals for currently reimbursed radiopharmaceuticals with a demonstrated overall survival benefit. A cost model that calculated the direct medical per-patient costs of radium-223 and 177Lu-PSMA-I&T was developed, following clinical trial regimens. The model considered six 4-weekly administrations (i.e. ALSYMPCA regimen) of radium-223. Regarding 177Lu-PSMA-I&T, the model used both the VISION regimen (i.e. five 6-weekly administrations) and the SPLASH regimen (i.e. four 8-weekly administrations). Based on health insurance claims, we also estimated the coverage a hospital would receive for providing treatment. No fitting health insurance claim for 177Lu-PSMA-I&T is currently available; therefore, we calculated a break-even value for a potential health insurance claim that would exactly counterbalance the per-patient costs and coverage. Radium-223 administration is associated with per-patient costs of €30,905, and these costs are fully covered by the coverage a hospital receives. The per-patient costs of 177Lu-PSMA-I&T range between €35,866 and €47,546 per administration period, depending on the regimen. Current healthcare insurance claims do not fully cover the costs of providing 177Lu-PSMA-I&T: hospitals must pay €4,414–€4,922 for each patient out of their own budget. The break-even value for the potential insurance claim covering 177Lu-PSMA-I&T administration with a VISION (SPLASH) regimen is €1,073 (€1,215). This study shows that, without consideration of the treatment effect, radium-223 treatment for mCRPC leads to lower per-patient costs than treatment with 177Lu-PSMA-I&T. The detailed overview of the costs associated with radiopharmaceutical treatment provided by this study is relevant for both hospitals and healthcare insurers. Prostate cancer is the most common form of cancer among men in the Netherlands, and its treatment is increasingly expensive. Given the limited hospital budget, it is important to consider costs in the treatment of prostate cancer. Radiopharmaceuticals are one of the multiple treatment options for metastatic prostate cancer. The current study looked at the costs of two radiopharmaceuticals, radium-223 and 177Lu-PSMA-I&T, while using multiple treatment regimens. The cost of radium-223 treatment is €30,905 per patient and is fully covered by insurance. The cost of 177Lu-PSMA-I&T treatment ranges from €35,866 to €47,546 per patient and is partially paid from the budget of the hospitals considering current reimbursement amounts. The study shows that, without consideration of the treatment effects, radium-223 treatment for prostate cancer leads to lower per-patient costs than treatment with 177Lu-PSMA-I&T. The detailed overview of the costs associated with radiopharmaceutical treatment provided by this study is relevant for both hospitals and healthcare insurers to manage prostate cancer treatment costs.
