简要总结
This is a Phase IV, randomized, active-controlled, open-label, parallel design, multicenter prospective study to evaluate the effect of roxadustat versus rHuEPO treatment on the gastrointestinal (GI) iron absorption in patients with anemia of Stage 4 and Stage 5 CKD.
详细描述
This is an open-label study, after eligibility confirmation patients will be randomized in a 1:1 ratio to either roxadustat or rHuEPO arms for 2 weeks.
The study will enroll eligible dialysis and non-dialysis patients ≥18 years of age, who have anemia of CKD, and are either dialysis-dependent (DD) and on a stable dose of rHuEPO within 4 weeks prior to screening, or are non-dialysis-dependent (NDD) and are being treated with rHuEPO (ie, on a stable dose of rHuEPO within 4 weeks prior to screening), or are rHuEPO -naïve at the time of screening.
Each patient will be contacted before the first Screening Visit (Visit 1) for the symptoms of coronavirus disease of 2019 (COVID-19) and for any contact with COVID-19 positive person within the past 14 days.
For each patient, the duration of participation in the study will be approximately 8 to 9 weeks divided into 3 periods: Screening Period (approximately 2-3 weeks); Treatment Period (2 weeks) and Post-Treatment Follow-up Period (4 weeks).

入选标准
- •Informed consent • Provision of signed and dated, written informed consent form (ICF) prior to any mandatory study specific procedures, sampling, and analyses.
- •Type of patient and disease characteristics
- •At Visit 1 prior to screening
- •Dialysis patients:
- •Patients receiving hemodialysis (HD) or peritoneal dialysis (PD) for treatment of end-stage renal disease (ESRD) for at least 12 weeks. Patients treated with HD must have access consisting of an arteriovenous (AV) fistula, AV graft, or tunneled (permanent) catheter. Patients on PD must have a functioning PD catheter in place.
- •Hemodialysis patients should be on 3x/week dialysis with evidence of achievement of adequate dialysis as defined by standardized Kt/V ≥2.1 in HD, and total (renal + PD) weekly Kt/V ≥1.7 in PD documented twice during the 16 weeks preceding screening for the study.
- •Patients should be on a stable rHuEPO dose as defined by change in rHuEPO dose, not exceeding 20% within 4 weeks prior to screening.
- •Non-dialysis patients:
- •Patients with estimated glomerular filtration rate (eGFR) <30 mL/minute/1.73 m^2, corresponding to Stage 4 or Stage 5 CKD according to the Kidney Disease Outcomes Quality Initiative (KDOQI), and not receiving dialysis.
- •Patients should either be on a stable dose of rHuEPO for 4 weeks before screening or be rHuEPO-naïve.
- •Dialysis and non-dialysis patients:
- •Patients agree not to take any new traditional Chinese medicine (TCM) and not to change, dose, schedule or brand of any TCM from beginning of the Screening Period through the end of the Follow-up Period.
- •At Visit 1 (screening)
- •Ferritin ≥50 ng/mL and transferrin saturation (TSAT) ≥15% in non-dialysis patients
- •Ferritin ≥100 ng/mL and TSAT ≥20% in dialysis patients.
- •Dry body weight should be 45 to 100 kg.
- •During the Screening Period:
- •Dialysis patients must have a mean Hb level of ≥ 9 to ≤ 12 g/dL based on the mean of the 2 most recent central laboratory Hb values within 0.50 g/dL on 2 assays taken at least 7 days apart during the Screening Period.
- •Non-dialysis patients must have a mean Hb level of ≥ 9 to ≤ 12 g/dL for rHuEPO-user patients and ≥ 7 and ≤ 10 g/dL for rHuEPO-naïve patients, based on the mean of the 2 most recent central laboratory Hb values within 0.50 g/dL on 2 assays taken at least 7 days apart during the Screening Period.
- •At Visit 1 Screening:
- •Serum folate level ≥ lower limit of normal (LLN).
- •Serum vitamin B12 level ≥ LLN.
- •Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) ≤ 3 x ULN and total bilirubin (TBL) ≤ 1.5 x ULN.
- •Negative test results on the swab test to rule out active COVID-19 infection. If according to site procedures the test for COVID-19 infection cannot be performed at the first Screening Visit, the test should be performed as soon as possible thereafter but must be performed before the patient returns for the next study visit. Any patient who has had confirmed COVID-19 infection in the past, has fully recovered from symptoms at least 14 days prior to Screening, and has a negative swab test result for COVID-19 infection at Screening, may be included in the study.
- •Reproduction:
- •Serum pregnancy test should be negative for female of childbearing potential at the start of the Screening Period.
- •Female patients of childbearing potential and male patients (non-surgically sterile) with a female partner of childbearing potential must, if not practicing complete sexual abstinence, agree to practice a dual method of contraception.
- •Contraceptive methods must be practiced upon being randomized to the study and through 7 days after the last dose of study treatment. Male patients must not donate or bank sperm during this same time period.
