African-Americans with sickle cell trait, carriers for sickle cell but without the disease, have no greater risk of cognitive decline than other adults of similar age, an analysis of a large population study shows. The study “Sickle cell trait and risk of cognitive impairment in African-Americans: The REGARDS cohort” was…

Survival of sickle cell disease patients (SCD) with end-stage renal disease who undergo kidney transplant is significantly lower compared to other renal disease patients who have the same procedure, a retrospective analysis shows. That finding, “Survival and specific outcome of sickle cell disease patients after renal transplantation,” was…

The Phase 3 RESET trial testing the effectiveness and safety of rivipansel (GMI-1070), Pfizer‘s investigational candidate to treat vaso-occlusive crisis (VOC) in hospitalized patients with sickle cell disease (SCD), failed to reach both its primary and secondary goals, top-line study results show. “We are disappointed with the results, as we…

Children with sickle cell disease, like adults, have a distinct group of immune cells, called innate like T-cells, that appear to promote the chronic inflammation associated with SCD, researchers report. Their work “Innate-like T cells in children with sickle cell disease” was published in the journal PLOS…

A non-invasive prenatal test to diagnose a risk of sickle cell disease in a baby is possible and may be available in clinics in a near future, if further testing confirms its efficacy, researchers in the U.K. report. Julia van Campen presented the first results of the non-invasive test in…

Treatment with hydroxyurea since early infancy, starting at the age of one, is effective and safe at preventing sickle cell disease (SCD) complications, a follow-up study has found. The study “Prospective longitudinal follow-up of children with sickle cell disease treated with hydroxyurea since infancy” was published in journal…

Imara’s investigational oral inhibitor IMR-687 is well-tolerated, and shows signs of potential for lowering blood biomarkers of sickle cell anemia (SCA), early data from a Phase 2 trial show. The results were presented at the 24th Congress of the European Hematology Association (EHA), held recently in…

The Phase 2 STRONG-SCD clinical trial evaluating olinciguat as an investigational therapy for sickle cell disease is seeking participants. Olinciguat, being developed by Cyclerion Therapeutics (a spin-off of Ironwood Pharmaceuticals), is an investigational oral therapy that stimulates an enzyme called soluble guanylate cyclase (sGC), known to play a key…

Adults with sickle cell disease score worse than their healthy, unaffected siblings on cognitive tests, despite treatment with hydroxyurea, a study reports. The study “Neurocognitive functioning in symptomatic adults with sickle cell disease: A description and comparison with unaffected siblings” was published in the journal Neuropsychological…

The success rate of bone marrow transplants for patients with sickle cell disease or beta thalassemia, from only “half-matched” donors, increased by doubling the radiation delivered to patients’ bodies before the transplants, a John Hopkins University study shows. The study, “Effect of increased dose of total body irradiation on…
