Two recent launches in oncology may keep the company's momentum going for years. Calquence is off to a fast start, generating $195 million in product sales in the first half. But the biggest winner in the long term could be Enhertu, a product of the company's partnership with Daiichi Sankyo. Last year, market research firm EvaluatePharma estimated the collaboration to be one of the top three most valuable R&D programs in the industry. Enhertu has been approved for third-line treatment of HER2-positive metastatic breast cancer and has been granted breakthrough therapy designation for metastatic gastric and non-small cell lung cancer as well.
