Compensatory Hyperfiltration Can Result in Asymptomatic ADPKD, Icon

Patients with ADPKD may remain asymptomatic for years while the disease progresses, likely due to compensatory hyperfiltration5,6

Role of Vasopressin in ADPKD Progression

JYNARQUE is a disease-modifying treatment7 that works by selectively inhibiting the binding of vasopressin at the V2-receptor in the kidney

JYNARQUE® (tolvaptan) Mechanism of Action
JYNARQUE® (tolvaptan) Mechanism of Action

Changes in urine osmolality reflect activity of JYNARQUE in the kidney 

  • In the early dose-finding studies of tolvaptan for ADPKD, Uosm was chosen as the biomarker of V2‑receptor inhibition8,9
    • Efficacy was defined by the capacity to suppress the action of vasopressin on the kidney, defined by the capacity to achieve a sustained Uosm of <300 mOsm/kg8
  • If a patient on JYNARQUE experiences a decrease in urine osmolality (sustained Uosm <300 mOsm/kg), it suggests that JYNARQUE is inhibiting the binding of vasopressin at the V2‑receptor in the kidney7
  • A decrease in Uosm to <300 mOsm/kg results from an increase in free water clearance and resultant excretion of more dilute urine

INDICATION and IMPORTANT SAFETY INFORMATION

JYNARQUE is indicated to slow kidney function decline in adults at risk of rapidly progressing autosomal dominant polycystic kidney disease (ADPKD).

WARNING: RISK OF SERIOUS LIVER INJURY

WARNING: RISK OF SERIOUS LIVER INJURY

  • JYNARQUE® (tolvaptan) can cause serious and potentially fatal liver injury. Acute liver failure requiring liver transplantation has been reported
  • Measure transaminases (ALT, AST) and bilirubin before initiating treatment, at 2 weeks and 4 weeks after initiation, then monthly for the first 18 months and every 3 months thereafter. Prompt action in response to laboratory abnormalities, signs, or symptoms indicative of hepatic injury can mitigate, but not eliminate, the risk of serious hepatotoxicity
  • Because of the risks of serious liver injury, JYNARQUE is available only through a Risk Evaluation and Mitigation Strategy program called the JYNARQUE REMS Program

CONTRAINDICATIONS:

  • History, signs or symptoms of significant liver impairment or injury. This contraindication does not apply to uncomplicated polycystic liver disease
  • Taking strong CYP3A inhibitors
  • With uncorrected abnormal blood sodium concentrations
  • Unable to sense or respond to thirst
  • Hypovolemia
  • Hypersensitivity (e.g., anaphylaxis, rash) to JYNARQUE or any component of the product
  • Uncorrected urinary outflow obstruction
  • Anuria

Serious Liver Injury: JYNARQUE can cause serious and potentially fatal liver injury. Acute liver failure requiring liver transplantation has been reported in the post-marketing ADPKD experience. Discontinuation in response to laboratory abnormalities or signs or symptoms of liver injury (such as fatigue, anorexia, nausea, right upper abdominal discomfort, vomiting, fever, rash, pruritus, icterus, dark urine or jaundice) can reduce the risk of severe hepatotoxicity. To reduce the risk of significant or irreversible liver injury, assess ALT, AST and bilirubin prior to initiating JYNARQUE, at 2 weeks and 4 weeks after initiation, then monthly for 18 months and every 3 months thereafter.

Hypernatremia, Dehydration and Hypovolemia: JYNARQUE therapy increases free water clearance which can lead to dehydration, hypovolemia and hypernatremia. Instruct patients to drink water when thirsty, and throughout the day and night if awake. Monitor for weight loss, tachycardia and hypotension because they may signal dehydration. Ensure abnormalities in sodium concentrations are corrected before initiating therapy. If serum sodium increases above normal or the patient becomes hypovolemic or dehydrated and fluid intake cannot be increased, suspend JYNARQUE until serum sodium, hydration status and volume status parameters are within the normal range.

Inhibitors of CYP3A: Concomitant use of JYNARQUE with drugs that are moderate or strong CYP3A inhibitors (e.g., ketoconazole, itraconazole, lopinavir/ritonavir, indinavir/ritonavir, ritonavir, and conivaptan) increases tolvaptan exposure. Use with strong CYP3A inhibitors is contraindicated; dose reduction of JYNARQUE is recommended for patients taking moderate CYP3A inhibitors. Patients should avoid grapefruit juice beverages while taking JYNARQUE.

Adverse Reactions: Most common observed adverse reactions with JYNARQUE (incidence >10% and at least twice that for placebo) were thirst, polyuria, nocturia, pollakiuria and polydipsia.

Other Drug Interactions:

  • Strong CYP3A Inducers: Co-administration with strong CYP3A inducers reduces exposure to JYNARQUE. Avoid concomitant use of JYNARQUE with strong CYP3A inducers
  • V2-Receptor Agonist: Tolvaptan interferes with the V2-agonist activity of desmopressin (dDAVP). Avoid concomitant use of JYNARQUE with a V2-agonist

Pregnancy and Lactation: Based on animal data, JYNARQUE may cause fetal harm. In general, JYNARQUE should be discontinued during pregnancy. Advise women not to breastfeed during treatment with JYNARQUE.
