The results of the ONgoing Telmisartan Alone and in combination with Ramipril Global Endpoint Trial (ONTARGET) study were unexpected, demonstrating no cardiovascular or renal benefit but substantial adverse effects of adding an angiotensin II receptor blocker (ARB), telmisartan 80 mg/day, to an angiotensin-converting enzyme (ACE) inhibitor, ramipril 10 mg/day (dual therapy) vs ramipril alone [1,2]. Those results stirred up a number of commentaries especially from the nephrological community and in most major nephrological journals [3–11]. In this journal, Dr. Abutaleb [10] brings up a number of concerns related to the design and the renal results of ONTARGET, and we will reply to those concerns in the following. From the beginning, we would like to stress that ONTARGET is the only reliable outcome trial at present to build our judgment on dual therapy outside heart failure and one flawed renal study [13,14].
