Justify Sample Size Hike in FDC Trial of Zibotentan-Dapagliflozin, CDSCO Panel Tells AstraZeneca

Zibotentan is an orally available selective antagonist of the endothelin-A (ET-A) receptor with potential antineoplastic activity. Zibotentan binds selectively to the ET-A receptor, thereby inhibiting endothelin-mediated mechanisms that promote tumor cell proliferation.

Dapagliflozin is in a class of medications called sodium-glucose co-transporter 2 (SGLT2) inhibitors. It lowers blood sugar by causing the kidneys to get rid of more glucose in the urine.

Dapagliflozin is used together with proper diet and exercise to treat type 2 diabetes. It works in the kidneys to prevent absorption of glucose (blood sugar). This helps lower the blood sugar level. Dapagliflozin does not help patients who have insulin-dependent or type 1 diabetes.
