The affected patients have already received an endocrine therapy and at least 1 line of chemotherapy, and the disease has progressed on the last therapy.
The medicinal product DATROWAY was authorised as part of the joint initiative of the Access Consortium. This joint initiative is a collaborative project between the drug regulatory authorities in Australia (Therapeutic Goods Administration, TGA), Canada (Health Canada, HC), Singapore (Health Sciences Authority, HSA), the United Kingdom (Medicines & Healthcare products Regulatory Agency, MHRA), and Swissmedic. The joint initiative coordinates the assessment of authorisation applications for new active substances that have been submitted in at least 2 of the 5 countries.
The authorisation application for DATROWAY was submitted to the drug regulatory authorities in Singapore, Australia, and Switzerland. Each country assessed a part of the application and then shared and discussed the results. At the end of the process, each authority decided on the application independently.

The requirements for issuing a comprehensive SwissPAR (Swiss Public Assessment Report) and a Summary report on authorisation based on this SwissPAR have not been fulfilled.
