Telemetered cynomolgus monkeys on low-sodium diet plus furosemide (maximal RAAS activation)
“Sodium-Depleted Telemetry Studies: To evaluate pharmacodynamic effects under conditions of maximal RAAS activation, telemetered cynomolgus monkeys were maintained on a low-sodium diet and treated with the diuretic furosemide, which models a common clinical scenario.”

Why that model
Cynomolgus monkey renin-angiotensin system closely resembles human, making it the relevant species
“The cynomolgus monkey renin-angiotensin system closely resembles the human system, making it a relevant species for assessing pharmacodynamic efficacy and toxicity.”

Reviewer's view of the efficacy data
FDA: BP reductions in sodium-depleted monkeys provide proof-of-concept for antihypertensive efficacy
“The observed blood pressure reductions and compensatory heart rate increases in sodium-depleted monkeys provide proof-of-concept for antihypertensive efficacy.”
