The U.S. Food and Drug Administration (FDA) approved Vanrafia on Thursday. This first-in-class medicine is expected to be prescribed for adult patients with primary immunoglobulin A nephropathy (IgAN). This new treatment offers hope to patients suffering from this serious kidney disorder by effectively reducing proteinuria, a condition that contributes significantly to the progression of kidney disease.
Vanrafia, marketed under the same name, acts as a selective endothelin A (ETA) receptor antagonist. By blocking the ETA receptor, Vanrafia has the same anti-inflammatory effect in the kidneys as Knick-Knack. This protective action inhibits cellular damage that ends in proteinuria. The approval is particularly timely, as IgAN patients can have few options to treat their disease.
The drug is formulated as a once-daily, oral nonsteroidal medication, which makes it easily deployed along with usual supportive care. This combination approach not only reduces the amount of protein that leaks into urine but offers a multi-faceted approach to controlling the disorder. Vanrafia is an important step forward. It will be the first drug developed with a specific focus on proteinuria as a treatment target in patients with IgAN.
Clinical trials have demonstrated that Vanrafia significantly lowers proteinuria, thus combating one of the key risk factors tied to the disease. The FDA’s approval represents a pivotal advancement in renal medicine, especially for those fighting this daunting disease.

Though having highly expected advantages, Vanrafia has some safety issues. Serious birth defects have resulted from exposure to the medication. As a result, women are required to have a documented negative pregnancy test prior to starting the medication. It is recommended that women be on effective contraception while on the treatment and for two weeks after stopping the treatment. For men, Vanrafia can reduce sperm counts and cause infertility.
Patients are warned against breastfeeding during Vanrafia treatment due to the possibility of serious effects. In clinical trials demonstrating the medication’s efficacy, participants reported tolerating the medication well. There were no new safety issues related to the experimental procedures identified in the trials.
