About

This study is a single-dose, parallel grouping, open-label phase I clinical study to evaluate the PK characteristics and safety of single subcutaneous injection of PB-119 in subjects with different degrees of renal insufficiency and matched subjects with normal renal function.

Full description

This study plans to enroll 24 subjects, which are divided into three groups: Group A: subjects with mild renal insufficiency (chronic kidney disease [CKD] stage 2); Group B: subjects with moderate renal insufficiency (CKD3 stage 3); Group C: subjects with normal renal function. The estimated glomerular filtration rate (eGFR, mL/min/1.73m2) transformed according to the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formula should be converted into individual glomerular filtration rate (GFR, mL/min) as an indicator of CKD grading, and subjects should be stratified according to different degrees of renal function.

Inclusion criteria

  • All subjects included in this study must meet all of the following criteria:

  2. Fertile women should voluntarily take effective contraceptive measures from the screening period to 90 days after the administration of the study drug;

  3. According to the judgment of the investigators, the subject's physical examination, vital signs examination, 12 lead ECG examination and laboratory examination indicators are suitable for participating in this study;

    Subjects in the renal insufficiency group must also meet the following criteria:

Subjects with a diagnosis of chronic (> 3 months) and stable (no acute exacerbation due to renal function aggravated within 1 month before screening) renal injury, and a GFR measured during the screening period in line with 60 89 mL/min (mild renal insufficiency in group A) or 30-59 mL/min (moderate renal insufficiency in group B). Renal function evaluated by individual GFR converted from eGFR calculated according to the CKD-EPI formula;

    Subjects in the normal renal function group must also meet the following criteria:

  7. Male or female subjects aged between 18 and 75 years old, which should be matched with age (±10 years) and gender of subjects in the renal insufficiency group;

  9. The GFR of subjects with normal renal function should be ≥ 90 and < 130 mL/min (estimated by CKD-EPI formula).
