HONG KONG – Eisai Co. Ltd. has received not one, but two approvals from Japan’s Ministry of Health, Labour and Welfare (MHLW), for its anticancer agent Remitoro (denileukin diftitox) and multiple receptor tyrosine kinase inhibitor Lenvima (lenvatinib mesylate). Both approvals, each for a rare disease indication, were granted based on phase II trial results, instead after the usual phase III trials.
Suzhou-China based Cstone Pharmaceuticals Co. Ltd., which in-licensed RET inhibitor pralsetinib from Blueprint Medicines Corp. in 2018, has won Chinese approval for the drug to treat adult patients with locally advanced or metastatic RET fusion-positive non-small-cell lung cancer after platinum-based chemotherapy. Already approved as Gavreto in the U.S., the drug is Cstone’s first product approved in China and the country’s first selective RET inhibitor.
