Chemistry:Fevipiprant
Fevipiprant (INN; code name QAW039) is a drug of the piprant class that was being developed by Novartis. It is a selective, orally available antagonist of the prostaglandin D2 receptor 2 (DP2 or CRTh2).[1][2][3]
By 2016 it had advanced to phase III[4] clinical trials for the treatment of asthma.[5] However, in 2019 Novartis announced that it was removing fevipiprant from its development program, given that the medicine has failed in two clinical trials in patients with moderate-to-severe asthma. The firm said that it had hoped fevipiprant would be a billion-dollar-selling asthma drug.[6]
A 2021 analysis sponsored by Novartis of the two phase III trials of fevipiprant concluded that "The ZEAL studies did not demonstrate significant improvement in lung function or other clinical outcomes. These results suggest that DP2 receptor inhibition with fevipiprant is not effective in the studied patient population".[7]
