- DB12548
- Background
Sparsentan is a dual antagonist of the endothelin type A receptor (ETAR) and the angiotensin II (Ang II) type 1 receptor (AT1R) with a similar affinity for both (9.3 nM for ETAR and 0.8 nM for AT1R).2,5 Sparsentan is first in its class and orally active, and was created by merging the structural elements of irbesartan, an AT1R antagonist, and biphenylsulfonamide, an ETAR antagonist.2
In February 2023, the use of sparsentan to reduce proteinuria in adults with primary immunoglobulin A nephropathy (IgAN) at risk of rapid disease progression was approved by the FDA under accelerated approval based on reduction of proteinuria.5,7 Sparsentan was initially developed for the treatment of hypertension;4 however, it has shown to be efficient in the reduction of proteinuria in patients with IgAN and focal segmental glomerulosclerosis (FSGS).1,3,6 Compared to irbesartan, sparsentan reduces proteinuria to a greater extent. Furthermore, it is the first non-immunosuppressive therapy for the reduction of proteinuria in IgAN.7 The use of sparsentan may cause hepatotoxicity and embryo-fetal toxicity.5

- Pharmacodynamics
Sparsentan is a dual endothelin and angiotensin II receptor antagonist. At week 36, the exposure-response (E-R) relationship between sparsentan exposure and the percentage reduction from baseline in urine protein-to-creatinine ratio (UPCR) was not statistically significant over the observed sparsentan exposure range. E-R relationships were not statistically significant for any grade of hypotension or the worst grade of peripheral edema.5
In healthy subjects, sparsentan caused QTcF prolongation with a maximal mean effect of 8.8 msec at 800 mg and 8.1 msec at 1600 mg. The mechanism behind the observed QTc prolongation is unknown but is unlikely to be mediated via direct inhibition of hERG channels. At the recommended dose, no clinically relevant QTc prolongation is expected. The use of sparsentan may cause hepatotoxicity, embryo-fetal toxicity, hypotension, acute kidney injury, hyperkalemia, and fluid retention.5
- Mechanism of action
Sparsentan is a molecule that acts as a dual antagonist of the endothelin type A receptor (ETAR) and the angiotensin II (Ang II) type 1 receptor (AT1R).5 It possesses two clinically validated mechanisms of action and selectively blocks the action of two potent vasoconstrictor and mitogenic agents, Ang II and endothelin 1 (ET-1), at their respective receptors.2 ET-1 and Ang II contribute to the pathogenesis of immunoglobulin A nephropathy (IgAN), a condition characterized by the increased production of galactose-deficient IgA1 (Gd-IgA1) antibodies. Gd-IgA1 antibodies lead to mesangial cell activation and proliferation, which stimulates and is stimulated by ET-1 and Ang II production. The pathological cycle of IgAN results in a compromised glomerular filtration barrier and subsequent proteinuria and haematuria.6 By acting as both an angiotensin receptor blocker (ARB) and an endothelin receptor antagonist (ERA), sparsentan reduces proteinuria in patients with IgAN.1,3,6 Sparsentan has a high affinity for both ETAR (Ki= 12.8 nM) and AT1R (Ki=0.36 nM), and greater than 500-fold selectivity for these receptors over the endothelin type B and angiotensin II subtype 2 receptors.5
Target Actions Organism AEndothelin-1 receptor antagonistHumans AType-2 angiotensin II receptor antagonistHumans - Absorption
Following administration of single doses of 200-1600 mg, the Cmax and AUC of sparsentan increase in a less than dose-proportional manner. Sparsentan has time-dependent pharmacokinetics, possibly due to it inducing its own metabolism over time, and at the approved recommended dosage, it reaches steady-state plasma levels within 7 days. Following a single oral dose of 400 mg, the Cmax, AUC and median time to peak plasma concentration of sparsentan are 6.97 μg/mL, 83 μg×h/mL, and 3 hours, respectively. Following daily doses of 400 mg sparsentan, the steady-state Cmax is 6.47 μg/mL, and the AUC is 63.6 μg×h/mL. The administration of a single oral dose (800 mg) of sparsentan with a high-fat, high-calorie meal (1000 kcal, 50% fat) increased the AUC and Cmax by 22% and 108%, respectively. With a single 200 mg dose, a high-fat, high-calorie meal did not have a clinically significant effect on sparsentan pharmacokinetics.5
- Volume of distribution
At the approved recommended dosage, sparsentan has an apparent volume of distribution at steady state of 61.4 L.5
- Protein binding
Sparsentan is more than 99% bound to human plasma proteins.5
- Metabolism
Sparsentan is mainly metabolized by cytochrome P450 3A.5
- Route of elimination
Sparsentan is mainly excreted through feces and urine. In healthy subjects given a single dose (400 mg) of radiolabeled sparsentan, approximately 80% of the dose was recovered in feces (9% unchanged) and 2% in urine (negligible amount unchanged). Within a 10-day collection period, 82% of the dosed radioactivity was recovered.5
- Half-life
Sparsentan has an estimated half-life of 9.6 hours at steady state.5
- Clearance
Sparsentan has a time-dependent clearance, possibly due to it inducing its own metabolism over time. Following the initial 400 mg dose, sparsentan has an apparent clearance of 3.88 L/h. At steady state, the apparent clearance increases to 5.11 L/h.5

- Toxicity
No overdose experience has been reported with sparsentan. Doses up to 1600 mg/day and 400 mg/day have been given to healthy volunteers and patients, respectively. Overdose of sparsentan may result in decreased blood pressure. Provide standard supportive measures, as required, in case of an overdose. Since sparsentan is highly protein-bound, dyalisis may not be effective.5 A 2-year rat carcinogenicity study where male and female mice received 0.7 and 26 times the AUC at the maximum recommended human dose (MRHD), respectively, found no evidence of increased incidence of neoplasia. A 26-week transgenic mouse study reported similar results. In vitro bacteria reverse mutation and chromosomal aberration assays and an in vivo rat micronucleus study did not find evidence of mutagenicity or clastogenicity for sparsentan. Sparsentan did not lead to an impairment of fertility in male or female rats and monkeys.5
