Reata gets CRL on chronic kidney med

Reata Pharmaceuticals, Inc. (Nasdaq: RETA) ("Reata," the "Company," or "we"), today announced that the U.S. Food and Drug Administration ("FDA") has issued a Complete Response Letter ("CRL") regarding the New Drug Application ("NDA") for bardoxolone methyl ("bardoxolone") for the treatment of patients with chronic kidney disease ("CKD") caused by Alport syndrome.

The CRL indicates that the FDA cannot approve the NDA in its present form. Based on its review, the FDA concluded that it does not believe the submitted data demonstrates that bardoxolone is effective in slowing the loss of kidney function in patients with Alport syndrome and reducing the risk of progression to kidney failure and has requested additional data to support the efficacy and safety of bardoxolone. Their conclusion was based on efficacy and safety concerns primarily set forth in the FDA’s briefing book and discussed at the Cardiovascular and Renal Drugs Advisory Committee meeting held on December 8, 2021.

The FDA stated that the issues could be resolved by providing evidence of effectiveness that includes evidence from an adequate and well-controlled study showing a clinically relevant effect on the rate of loss of kidney function in patients with Alport syndrome or, alternatively, an effect on a clinical outcome (i.e., an endpoint that captures how patients with Alport syndrome feel, function, or survive). In addition, the FDA stated that we would need to address whether bardoxolone has a clinically relevant effect on the QT interval and show that the demonstrated clinical benefits of bardoxolone outweigh its risks. The FDA welcomed continued discussion on the details of a path forward. We plan to work closely with the FDA to bring this important medicine to patients in the US.
