The top drug regulator, the FDA, has indicated in its first speech to staff that it will investigate antidepressants and injections to protect children against RSV[original content]. The article mentions Grail's cancer blood test, known as Galleri, which detects more than 50 types of tumors[1][3][5]. In the British SYMPLYFY study of 5,461 patients suspected of having cancer, the test detected tumors in 323 of them, while the diagnosis was confirmed in 244 cases[1]. The test ruled out cancer in more than 97% of symptomatic patients and determined the origin of the tumor in 85% of detected cases[1]. The sensitivity of the test was 75% overall, 95.3% for stage IV and 24.2% for the earliest forms[1]. The results of the study were presented by experts from Oxford at the ASCO conference in Chicago[1]. The test detects circulating tumor DNA in the blood and promises early detection[3][6].
