          摘   要  目的  评价健康受试者空腹或餐后单次口服2种哌柏西利制剂的生物等效性。方法 分别纳入24例(空腹试验)和20例
         (餐后试验)健康受试者,均分为2组。采用单中心、开放、单剂量、两制剂、两周期、两序列、交叉试验设计,两组受试者分别空腹或
          餐后口服受试制剂(国产哌柏西利胶囊)或参比制剂(原研哌柏西利胶囊),清洗期为14 d。分别于用药前后不同时间点采集血样,
          经前处理后,以哌柏西利-d8为内标,采用高效液相色谱-串联质谱法测定其体内哌柏西利的质量浓度,采用SAS V9.4软件计算药
          动学参数并进行生物等效性评价。结果  在空腹状态下,受试制剂和参比制剂的 cmax分别为(71.4±18.1)、(73.8±19.0)ng/mL,
          AUC0-t分别为(1 754±412)、(1 793±448)h·ng/mL,AUC0-∞分别为(1 851±456)、(1 887±478)h·ng/mL;在餐后状态下,受试制剂
          和参比制剂的 cmax分别为(78.4±18.3)、(81.9±21.7)ng/mL,AUC0-t分别为(1 905±375)、(1 932±318)h·ng/mL,AUC0-∞分别为
         (2 027±411)、(2 050±342)h·ng/mL;两项试验上述参数几何均值比的90%置信区间均在可接受范围(80.00%~125.00%)内。空
          腹、餐后状态下,分别有9、8例受试者发生20、16次不良事件,但均未见严重不良事件发生。结论  在空腹、餐后状态下,哌柏西利
          胶囊受试制剂与参比制剂生物等效,且安全性相当。

          ABSTRACT    OBJECTIVE  To  evaluate  the  bioequivalence  of  a  single  oral  administration  of  two  palbociclib  preparations  in
          healthy  subjects  under  fasting  and  fed  conditions.  METHODS  Twenty-four  healthy  subjects (fasting  test)  and  twenty  healthy
          subjects (fed  test)  were  enrolled  and  divided  into  two  groups.  A  single-center,  open-label,  single-dose,  two-formulation,  two-
          period,  two-sequence  and  crossover  trial  was  designed.  The  subjects  in  the  two  groups  were  given  the  test  preparation (domestic
          Palbociclib capsules) or the reference preparation (original Palbociclib capsules) orally under fasting or fed conditions respectively
          followed  by  a  14-day  washout  period.  The  blood  samples  were  collected  at  different  time  points  before  and  after  treatment. After
          pretreatment,  the  mass  concentration  of  palbociclib  in  vivo  was  determined  by  high-performance  liquid  chromatography-tandem
          mass  spectrometry  with  palbociclib-d8  as  the  internal  standard.  SAS  V9.4  software  was  used  to  calculate  the  pharmacokinetic
          parameters  and  evaluate  the  bioequivalence.  RESULTS  Under  fasting  condition,  the  cmax  of  the  test  preparation  and  the  reference
          preparation  were (71.4±18.1)  and (73.8±19.0)  ng/mL; AUC0-t  were (1  754±412)  and (1  793±448)  h·ng/mL; AUC0-∞  were
         (1  851±456)  and (1  887±478)  h·ng/mL,  respectively.  Under  fed  condition,  the  cmax  of  the  test  preparation  and  the  reference
          preparation  were (78.4±18.3)  and (81.9±21.7)  ng/mL; AUC0-t  were (1  905±375)  and (1  932±318)  h·ng/mL; AUC0-∞  were
         (2  027±411)  and (2  050±342)  h·ng/mL,  respectively.  The  90%CI  of  the  geometric  mean  ratio  of  the  above  parameters  was
          within the acceptable range (80.00%-125.00%). Under fasting and fed conditions, there were 20 and 16 adverse events in 9 and 8
          subjects, respectively, but no serious adverse event was observed. CONCLUSIONS Under the fasting and fed conditions, the test
          preparation and the reference preparation of Pibociclib capsules are bioequivalent and have comparable safety.
