To discuss barriers and opportunities for the introduction of new antiretrovirals into national treatment programmes in low-income and middle-income countries to support further treatment scale-up. Invitees to a WHO Think Tank in February 2017 evaluated recently published results.
There is not sufficient clinical experience of dolutegravir (DTG), tenofovir alafenamide (TAF) or efavirenz 400 mg (EFV400) to recommend their use in pregnancy. Outcomes from births and assessment of congenital anomalies need to be evaluated from several hundred pregnant women. Clinical experience of these treatments during rifampicin-based treatment for tuberculosis is also required. This could be difficult for TAF, which is currently contraindicated with TAF. Changes in second-line treatment from two nucleoside analogues + protease inhibitor plus ritonavir will require new randomized trials of alternative combinations.
Additional safety and efficacy data on DTG, TAF and EFV400 in some subpopulations are needed before a large introduction in national treatment programmes. There is currently limited support for the introduction of TAF as part of first-line antiretroviral treatment in low-income and middle-income settings. There was an overall agreement for 6-monthly reviews of safety and efficacy data, in parallel with a phased introduction of the new antiretrovirals.
讨论在低收入和中等收入国家将新型抗逆转录病毒药物引入国家治疗方案以支持进一步扩大治疗规模的障碍和机遇。2017年2月世界卫生组织智库的受邀者评估了最近发表的结果。
多替拉韦(DTG)、替诺福韦艾拉酚胺(TAF)或400毫克依非韦伦(EFV400)在妊娠中的临床经验不足,无法推荐在妊娠中使用。需要对数百名孕妇的分娩结果和先天性异常评估进行评估。还需要这些治疗在基于利福平的抗结核治疗期间的临床经验。对于TAF来说这可能很困难,因为目前TAF有禁忌证。二线治疗从两种核苷类似物+蛋白酶抑制剂加利托那韦转变将需要对替代组合进行新的随机试验。
在大规模引入国家治疗方案之前,需要DTG、TAF和EFV400在某些亚人群中的更多安全性和有效性数据。目前在低收入和中等收入环境中,将TAF作为一线抗逆转录病毒治疗的一部分引入的支持有限。总体上同意对安全性和有效性数据进行每6个月一次的审查,同时分阶段引入新型抗逆转录病毒药物。
