EUR-1008 (ZENPEP® [pancrelipase] Delayed-Release Capsules) delayed-release capsules is a novel, enteric-coated, porcine-derived pancreatic enzyme product. This study evaluated the efficacy and safety of 2 doses of ZENPEP in patients with chronic pancreatitis (CP) and exocrine pancreatic insufficiency (EPI).
The effect of ZENPEP on the coefficient of fat absorption (CFA) was investigated in a randomized, double-blind, dose-response, crossover study with placebo run-in (7-9 days) and 2 treatment periods (9-11 days) composed of a high dose (7 × 20,000 lipase units per day) and a low dose (7 × 5000 lipase units per day).
Mean CFA was significantly higher with low- (88.9%) and high-dose (89.9%) ZENPEP versus placebo run-in (82%; P < 0.001; n = 72) with no difference between doses (P = 0.228, primary end point). In patients with baseline CFA less than 90% (n = 33), the high dose was significantly more effective (CFA: 84.1%) than the low dose (CFA: 81.1%; P < 0.001). Post hoc analysis revealed an increase in treatment effect with more severe EPI. Coefficient of nitrogen absorption (P < 0.001), body weight (P ≤ 0.021), and body mass index (P ≤ 0.020) also increased significantly with both doses compared with baseline. Percentage of days with EPI symptoms decreased with both doses.
Our findings suggest that CP patients with EPI benefit from a low dose of ZENPEP, whereas the high dose might be needed for patients with more severe EPI.
EUR-1008(Zenpep®[胰酶]延迟释放胶囊)延迟释放胶囊是一种新型的、肠溶性的、猪源衍生的胰腺酶产品。这项研究评估了 Zenpep 在慢性胰腺炎(CP)和外分泌胰腺功能不全(EPI)患者中的疗效和安全性。
在一项随机、双盲、剂量反应、交叉研究中,用安慰剂进行了为期 7-9 天的导入期,然后进行了为期 9-11 天的 2 个治疗期,研究了 Zenpep 对脂肪吸收系数(CFA)的影响。治疗期包括高剂量(每天 7×20000 脂肪酶单位)和低剂量(每天 7×5000 脂肪酶单位)。
低剂量(88.9%)和高剂量(89.9%)Zenpep 与安慰剂导入期(82%;P<0.001;n=72)相比,CFA 显著升高,且剂量间无差异(P=0.228,主要终点)。在基线 CFA 低于 90%的患者(n=33)中,高剂量(CFA:84.1%)明显比低剂量(CFA:81.1%;P<0.001)更有效。事后分析显示,EPI 越严重,治疗效果越好。氮吸收系数(P<0.001)、体重(P≤0.021)和体重指数(P≤0.020)也与基线相比显著增加。两种剂量的 EPI 症状天数百分比均减少。
我们的研究结果表明,EPI 的 CP 患者受益于低剂量的 Zenpep,而对于 EPI 更严重的患者,高剂量可能是必要的。
