一项Ⅱ期研究(JACKPOT8 Part B)共入组位于中国、美国、澳大利亚和韩国的49个医疗中心的104例既往接受过≥1次系统治疗的R/R PTCL成年患者,接受戈利昔替尼150 mg/d治疗,21 d为1个治疗周期,直到疾病进展或出现不可耐受的AE[13]。这一剂量来自Ⅰ期临床试验(JACKPOT Part A)中给出的Ⅱ期推荐剂量[10]。截至2023年8月31日,共有88例患者(包括74例中国患者)纳入主要疗效评估,客观缓解率(ORR)为44.3%(39/88),CR率为23.9%(21/88),其中NK/T细胞淋巴瘤的ORR为66.7%(2/3),AITL的ORR为56.3%(9/16),PTCL-NOS的ORR为46.0%(23/50),不确定类型的ORR为44.4%(4/9),ALCL的ORR为10.0%(1/10);中国和韩国患者的ORR为44.6%(37/83)[13]。中位随访12.5个月,中位缓解持续时间为20.7个月;中位随访11.9个月,中位无进展生存时间为5.6个月;中位随访17.5个月,预计中位总生存时间为19.4个月[13]。≥3级治疗中出现的不良事件(TEAE)发生率为69.2%,最常见的≥3级药物相关的TEAE均为血液学不良反应[13]。
在JACKPOT8 Part A研究中,共有4例因PCP导致停药的病例[10],在采取预防措施后,JACKPOT8 Part A研究后续队列及JACKPOT8 Part B研究中所有患者均未发生PCP[13]。建议PTCL患者在接受戈利昔替尼治疗前,根据自身感染风险和耐受情况使用PCP预防性药物,如甲氧苄啶/磺胺甲恶唑,若患者对甲氧苄啶/磺胺甲恶唑不耐受或有禁忌证,也可考虑服用其他PCP二线预防药物,如氨苯砜、喷他脒或阿托伐醌以减少PCP,具体用药建议可参考药物说明书或相关指南[10,13,30]。
