A Canadian Agency for Drugs and Technologies in Health (CADTH) therapeutic review concluded that bevacizumab and ranibizumab have similar efficacy and safety in treating retinal conditions and recommended bevacizumab be used as preferred initial therapy based on a cost-saving perspective. Such use would be off-label because bevacizumab is not approved for these conditions and has a serious safety warning (SSW) in its Product Monograph (PM) about intravitreal use.
To evaluate whether the Ontario Public Drug Programs (OPDP) reimbursement is provided only for off-label use for serious, life-threatening or severely debilitating conditions and not when the drug's PM contains a SSW against such use.
OPDP reimbursement criteria for non-palliative drugs from its frequently-requested Exceptional Access Program (EAP) and Limited Use (LU) lists were compared with approved indications and SSWs in the drugs' PMs.
Of 125 unique frequently-requested non-palliative EAP drugs, 12 included off-label use for serious conditions for which no alternative treatment exists. Eight of the 12 had SSWs, but only one warning for orally-administered sirolimus related directly to the OPDP-reimbursed off-label use. Of 29 injectable non-palliative LU drugs, one had off-label LU criteria allowing reimbursement for an unapproved indication and a SSW unrelated to the reimbursable indication.
Presently, OPDP only reimburse drugs for off-label use for the treatment of serious, life-threatening or severely debilitating conditions for which no alternative treatment exists. OPDP should not diverge from this approach by allowing cost-savings to trump appropriate drug use, which would set a unique and unprecedented example.
加拿大卫生药物和技术局(CADTH)的一项治疗评估得出结论,贝伐单抗和雷珠单抗在治疗视网膜疾病方面具有相似的疗效和安全性,并基于成本节约的角度建议将贝伐单抗用作首选初始治疗药物。这种使用属于超适应症用药,因为贝伐单抗未被批准用于这些疾病,并且其产品说明书(PM)中针对玻璃体内使用有严重安全警告(SSW)。
评估安大略省公共药物计划(OPDP)是否仅为治疗严重、危及生命或严重致残疾病的超适应症用药提供报销,而当药物的产品说明书中含有针对此类使用的严重安全警告时则不提供报销。
将OPDP从其常用的特殊准入计划(EAP)和有限使用(LU)清单中获取的非姑息性药物报销标准与药物产品说明书中的批准适应症和严重安全警告进行比较。
在125种常见的非姑息性EAP常用药物中,有12种包括用于无替代治疗的严重疾病的超适应症用药。这12种药物中有8种有严重安全警告,但只有口服西罗莫司的一项警告与OPDP报销的超适应症用药直接相关。在29种注射用非姑息性LU药物中,有一种有超适应症LU标准,允许报销未批准的适应症,且有一项与可报销适应症无关的严重安全警告。
目前,OPDP仅为治疗无替代治疗的严重、危及生命或严重致残疾病的超适应症用药报销。OPDP不应背离这一做法,允许节省成本优先于合理用药,因为这将开创一个独特且前所未有的先例。
