Study design

STUDY DESIGN

  • Phase 3, double-blind, placebo-controlled withdrawal trial
  • 1370 patients randomized 1:1 to treatment with JYNARQUE or placebo
    • 18 to 55 years of age: eGFR between 25 and 65 mL/min/1.73 m2
    • 56 to 65 years of age: eGFR between 25 and 44 mL/min/1.73 m2 plus eGFR decline >2.0 mL/min/1.73 m2/year
  • During the titration period, patients were up-titrated every 3 to 4 days with JYNARQUE
    • 30 mg AM + 15 mg PM/day
    • 45 mg AM + 15 mg PM/day
    • 60 mg AM + 30 mg PM/day
    • 90 mg AM + 30 mg PM/day
  • Only patients who could tolerate the 2 highest doses of JYNARQUE (60 mg/30 mg or 90 mg/30 mg) were randomized 1:1 to treatment with JYNARQUE or placebo; during the 12-month study, they could interrupt, decrease and/or increase the dose as clinical circumstances warranted
  • Primary end point: the treatment difference in the change of eGFR from pretreatment baseline to posttreatment follow-up, annualized by dividing by each participant's treatment duration

Key secondary composite end point

JYNARQUE DECREASED THE RELATIVE RATE OF ADPKD-RELATED COMPOSITE EVENTS BY 13.5%§

Key secondary composite end point

The key secondary composite end point (ADPKD progression) was time to multiple clinical progression events of:

 

 

 

Rate of ADPKD-Related Composite Events, TEMPO 3:4 Study
Rate of ADPKD-Related Composite Events, TEMPO 3:4 Study

The effect on the composite end point was driven by:

  • 61.4% reduction in the risk of an event of worsening kidney function (2 events per 100 person-years of follow-up in the tolvaptan group versus 5 in the placebo group; HR, 0.39; 95% CI, 0.26 to 0.57; P<0.0001)6
  • 35.8% reduction in the risk of an event of worsening pain (5 events per 100 person-years of follow-up in the tolvaptan group versus 7 in the placebo group; HR, 0.64; 95% CI, 0.47 to 0.89; P=0.007)6

In contrast, there was no effect of JYNARQUE on either progression of hypertension or albuminuria.

Secondary composite end point component: Renal pain events

Risk of Renal Pain Events in TEMPO 3:4 Study, Chart

JYNARQUE decreased the relative rate of ADPKD-related composite events by 13.5%

Third end point: Slope of eGFR

Change in Kidney Function in TEMPO 3:4 Study, Graph

This end point was assessed as slope of eGFR during treatment (from end of titration to last on-drug visit)

  • JYNARQUE-treated patients had a 26.4% reduction in the rate of kidney function decline compared with placebo (-2.7 versus -3.7 [mL/min/1.73 m2/year], P<0.0001)6
  • Of the subjects enrolled in the trial, 5% of subjects in the tolvaptan arm and 2% in the placebo arm either had missing baseline data or discontinued from treatment prior to the end of the titration visit and hence were excluded from the analysis.

INDICATION and IMPORTANT SAFETY INFORMATION for JYNARQUE® (tolvaptan)

INDICATION:

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

IMPORTANT SAFETY INFORMATION:

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
  • OATP1B1/3 and OAT3 Transporter Substrates: Patients who take JYNARQUE should avoid concomitant use with OATP1B1/B3 and OAT3 substrates (e.g., statins, bosentan, glyburide, nateglinide, repaglinide, methotrexate, furosemide), as the plasma concentrations of these substrates may be increased.
  • BCRP Transporter Substrates: Tolvaptan is an inhibitor of BCRP. Patients who take JYNARQUE, should avoid concomitant use with BCRP substrates (e.g., rosuvastatin)
  • 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.
