After observing a “reasonable” result on survival in blood cancer, the biotech axed its own applicant, turned to a preclinical program and provided 40% of its workers pink slips.The went down particle is a dual-sided combination healthy protein with 3 functional domains, a layout aimed to make it possible for macrophages to eat cancer tissues while turning on antigen-presenting cells as well as preventing anemia.
