Sickle cell disease (SCD) is associated with enhanced immune B-cell responses and the production of self-reactive antibodies that target and destroy red blood cells, according to data from a mouse model of the disease and patient samples. These changes in immune responses were regulated by type-1 interferons (IFN-1), an…

The first patient has been enrolled in a Phase 1 clinical trial evaluating the safety and tolerability of Rigel Pharmaceuticals’ fostamatinib — a medication approved in the U.S. for treating an autoimmune condition — in people with sickle cell disease (SCD). The Phase 1 study (NCT05904093) is…

Cognitive behavioral therapy (CBT) and pain education, each delivered using digital mobile systems and supported by a peer health coach, were equally effective at lessening the impact of sickle cell disease (SCD) pain, a study found. The U.S.-based clinical trial, CaRISMA (NCT04419168), involved more than 300 adults with…

Adding cyclosporin H to a new lentivirus-delivered gene therapy with enhanced anti-sickling properties boosted the uptake of genetic material in blood stem cells from newborns at risk of sickle cell disease (SCD), a preclinical study reports. With more genetic material inside stem cells, the therapy generated therapeutic levels of…

Zydus Lifesciences is launching a proof-of-concept Phase 2a clinical trial to evaluate the safety and efficacy of its oral candidate desidustat in people with sickle cell disease (SCD). The study is the result of a collaboration with the Indian Council of Medical Research (ICMR). “Public-private partnerships in the…

Pfizer has voluntarily withdrawn Oxbryta (voxelotor), a conditionally approved oral therapy for sickle cell disease (SCD), from worldwide markets, saying clinical data shows the treatment’s benefit “no longer outweighs the risk.” Citing an imbalance in vaso-occlusive crises (VOCs) and deaths occurring in patients given Oxbryta in postmarketing…

The American Institutes for Research (AIR) has been awarded a $28 million federal contract to help make cell and gene therapy (CGT) treatments more accessible to Medicaid recipients, initially focusing on sickle cell disease (SCD).

The U.S. Food and Drug Administration (FDA) gave the greenlight for Iomab-ACT, a potentially less toxic conditioning regimen, to be tested in people with sickle cell disease (SCD) undergoing a stem cell transplant. The study will be conducted in collaboration between Actinium Pharmaceuticals, which is developing Iomab-ACT,…

Hydroxyurea does not reduce ovarian reserve, or the quantity and quality of eggs in the ovaries, in girls and young women with sickle cell disease (SCD), according to a direct analysis of ovarian tissue. These findings suggest measures to preserve fertility may be unnecessary before hydroxyurea treatment. “This…
