New Resources for Clinical Trials

ASH has two new useful resources for conducting research: the ASH Toolkit for Clinical Trial Sponsors and the ASH Clinical Trials Map. These practical, expert-designed tools provide a range of actionable recommendations, reference articles, multimedia, and regulatory information from domestic and international bodies. Together these tools can help hematologists design clinical trials with broader representation for more generally applicable results. As you prepare your clinical research, check out the Toolkit and Map in our Research section.
