Dosing in Renal Impairment

The recommended dose is 2 mg once daily in patients with creatinine clearance between 30 and 60 mL/min. Baricitinib is not recommended for use in patients with creatinine clearance < 30 mL/min.1

Renal Impairment in Rheumatoid Arthritis Clinical Trials

In phase 3 studies, patients with an eGFR ≥40 and <60 mL/min/1.73 m2

  • received BARI 2 mg once daily if assigned to either the 2 mg or 4 mg BARI treatment arms, and 
  • were analyzed in the BARI 4-mg group if randomized to the BARI 4 mg treatment arm.2

Patients were excluded from the phase 3 studies if they had an eGFR <40 mL/min/1.73m2 calculated based on the most recent available serum creatinine using the MDRD method.2

Renal Function Subgroups for Pharmacokinetic and Safety Analyses

Renal impairment subgroups were defined using the eGFR ranges from the National Kidney Foundation Clinical Practice Guidelines for Chronic Kidney Disease. Subgroups by baseline eGFR included

  • none or normal defined as eGFR ≥90 mL/min/1.73 m2
  • mild defined as eGFR ≥60 to <90 mL/min/1.73 m2
  • moderate defined as eGFR ≥30 to <60 mL/min/1.73 m2
  • severe defined as eGFR 15 to <30 mL/min/1.73 m2, and
  • ESRD defined as requiring hemodialysis.2,3

Safety in Renal Impairment

Subgroup analyses were performed in BARI-treated patients using the renal function subgroup of none (n=1552), mild (n=1446), and moderate (n=175) dysfunction. Compared to patients with no renal impairment, patients with mild or moderate renal impairment had higher numerical EAIRs of

  • TEAEs (none 49.7, mild 52.5, moderate 60.4)
  • SAEs (none 7.0, mild 9.6, moderate 18.0), and
  • TEAEs leading to permanent discontinuation (none 4.0, mild 5.2, moderate 8.8).2

Placebo-controlled analyses do not suggest any clinically meaningful differences between BARI and placebo by baseline renal function.2


Baricitinib Eliminated by Glomerular Filtration and Active Secretion

Renal elimination is the principal mechanism for baricitinib’s clearance through glomerular filtration and active secretion via

  • OAT3,
  • Pgp,
  • BCRP and
  • MATE2-K.1

In a clinical pharmacology study, approximately 75 % of the administered dose was eliminated in the urine, while about 20 % of the dose was eliminated in the faeces.1

Baricitinib was excreted predominately as unchanged drug in urine (69%) and feces (15%).2

Baricitinib Exposure by Renal Function

Baricitinib exposure was evaluated in patients with mild, moderate, and severe renal impairment, including ESRD requiring hemodialysis, compared with healthy subjects with normal renal function.2

The dose-normalized geometric mean ratios of BARI exposure (AUC) relative to healthy subjects from each of the renally-impaired cohorts were

  • 1.41 for mild
  • 2.22 for moderate
  • 4.05 for severe
  • 3.18 for ESRD with hemodialysis predose, and
  • 2.41 for ESRD with hemodialysis postdose.2

The mean terminal half-life by subgroup was

  • 8.4 hours with normal renal function
  • 10 hours with mild renal impairment, and
  • 19 hours with severe renal impairment or ESRD.2

These results suggest that renal impairment significantly affects exposure to BARI, leading to increased exposure with decreasing renal function. Baricitinib does appear to be dialyzable.2

Information from the label

In rheumatoid arthritis, baricitinib induced a mean increase in serum creatinine levels of 3.8 µmol/L after two weeks of treatment, as compared to placebo, which remained stable thereafter during up to 104 weeks of treatment. This may be due to inhibition of creatinine secretion by baricitinib in the renal tubules.1

Consequently, estimates of the glomerular filtration rate based on serum creatinine may be slightly reduced, without actual loss of renal function or the occurrence of renal adverse events.1

Renal function was found to significantly affect baricitinib exposure.1

  • The mean ratios of AUC in patients with mild and moderate renal impairment to patients with normal renal function are 1.41 (90 % CI: 1.15-1.74) and 2.22 (90 % CI: 1.81-2.73), respectively.1
  • The mean ratios of Cmax in patients with mild and moderate renal impairment to patients with normal renal function are 1.16 (90 % CI: 0.92-1.45) and 1.46 (90 % CI: 1.17-1.83), respectively.1
