The aim of this contribution was to improve the pan-selectin affinity of rivipansel (3) by leveraging a new class of sLex mimetics in combination with an optimized linker length to the sulfate bearing group. As a result, the pan-selectin antagonist 11b exhibits an approximatively 5-fold improved affinity for E-, as well as P-selectin.
Our data in this mouse CKD model add new insights to the role of hepcidin in the development of CKD anemia over time. Furthermore, the results are promising and support further mechanistic and clinical studies to elucidate the therapeutic role for sevuparin as a treatment in anemia of inflammatory and/or chronic diseases in monotherapy or in combination with EPO and to explore its role in kidney protection.

The year 2017 marks a cornerstone in the treatment landscape of AML with the approval of midostaurin in the United States for newly diagnosed fit adults with FLT3 mutated AML. Subsequently, the therapeutic armamentarium of AML considerably expanded with the approval of enasidenib, ivosidenib, gilteritinib, and venetoclax in combination with hypomethylating agents and others...As a result, AML therapy is constantly evolving and so are the escape mechanisms leading to disease relapse. Therefore, it is of paramount importance to sequentially evaluate the patient during the course of AML treatment and intervene at the right time.
Preliminary results from this Phase I study reveals a tolerable safety profile of UPRO with AZA/VEN in pts with untreated AML ineligible for IC. No DLTs were observed, and the most common Grade 3-4 AE and SAE were hematologic. The combination shows promising preliminary efficacy, including a 50% rate of MRD-ve CR/CRi.
The combination produced an ORR of 62% in a high-risk, refractory population whose prognosis is very dismal. The relationship of E-selectin ligand expression, response to treatment, and outcomes is being analyzed.
