Optimal antihypertensive management in this setting remains unclear, and studies comparing angiotensin II receptor blockers (ARBs) and calcium channel blockers (CCBs) are limited. The objective of this study was to compare the effects oftheARBazilsartanand the CCB amlodipine on hypertension and proteinuria.  \nPatients and Methods: Patients with demonstrated systolic/diastolic blood pressure (SBP/DBP) ≥140/90 mmHg during Bev therapy for colorectal cancer were randomly assigned 1:1 to either the azilsartan group or the amlodipine group and were followed up for 18 weeks. The primary outcome was urinary protein-to-creatinine ratio (UPCR) . Secondary outcomes included BP changes and achievement of target BP (\u003C140/90 mmHg) . After week six, the attending physician adjusted the antihypertensive medication as needed.  \nResults: Thirty patients were enrolled, and 26 (13 per group) completed 18 weeks of treatment. Mean baseline SBP was 156.8±9.2 mmHg in the azilsartan group and 158.0±9.4 mmHg in the amlodipine group. At week six, SBP decreased to 151.4±21.9 mmHg and 144.5±15.2 mmHg, respectively, with a significant reduction in the amlodipine group. At week 18, SBP was 136.5±12.9 mmHg vs. 138.7±14.9 mmHg. Target BP was achieved in 23% of patients at week six and in 40-50% at week 18, with no difference between groups. No significant difference in UPCR was observed at anytime point. Subgroup analysis revealed that patients with proteinuria consistently had higher BP.  \ncontinued  \n✉ Satoru Nihei (ORCID iD: 0000-0003-3179-677X), Department of Pharmacy, Iwate Medical University Hospital, 2-1-1  \nIdaidori, Yahaba-cho, Shiwa-gun, Iwate 028-3695, Japan.

Inhibition of VEGF signaling suppresses tumor angiogenesis and prolongs survival (1), but frequently induces renal vascular adverse events such as hypertension and proteinuria (2-4) .
