Innovative Insurance to Improve US Patient Access to Cell and Gene Therapy
研究了2023-2035年美国全民覆盖细胞和基因治疗的年人均成本不到20美元，但费用集中在商业保险和州医疗补助计划中，再保险费用增加成本，需要政策改善覆盖和可负担性。
Policy Points Cell and gene therapies (CGTs) offer treatment for rare and oftentimes deadly disease, but their prices are high, and payers may seek to limit spending. Total annual costs of covering all existing and expected CGTs for the entire US population 2023-2035 to amount to less than $20 per person and concentrate in commercial and state Medicaid plans. Reinsurance fees add to expected costs. Policies that improve coverage and affordability are needed to assure patient access to CGTs. CONTEXT: Cell and gene therapies (CGTs) offer treatment to rare and oftentimes deadly diseases. Because of their high price and uncertain clinical outcomes, US insurers commonly restrain patient access to CGTs, and these barriers may create or perpetuate existing disparities. A reconsideration of existing insurance policies to improve access and reduce disparities is currently underway. One method insurers use to support access and protect them from large, unexpected claims is the purchase of reinsurance. In exchange for an upfront per-member-per-month (PMPM) premium, the reinsurer pays the claim and rebates the insurer at the end of the contract period if there are funds leftover. However, existing reinsurance plans may not cover CGTs or charge exorbitant fees for coverage. METHODS: We simulate the incremental annual per-person reinsurer costs to cover CGTs existing or expected between 2023 and 2035 for the US population and by payer type based on previously published estimates of expected US spending on CGTs, assumed US population of 330 persons, and current CGT reinsurance fees. We illustrate our methods by estimating the incremental annual per-person costs overall payers and to state Medicaid plans of sickle cell disease-targeted CGTs. FINDINGS: We estimate annual incremental spending on CGTs 2023-2035 to amount to $20.4 billion, or $15.69 per person. Total annual estimated spending is expected to concentrate among commercial plans. Sickle cell-targeted CGTs add a maximum of $0.78 PMPM in costs to all payers and will concentrate within state Medicaid programs. Reinsurance fees add to expected costs. CONCLUSIONS: Annual per-person costs to provide access to CGTs are expected to concentrate in commercial and state Medicaid plans. Policies that improve CGT coverage and affordability are needed.
