The serious adverse event in the first phase I/II patient dosed with nulabeglogene autogedtemcel (nula-cel) – a gene editing, autologous hematopoietic stem cell therapy for sickle cell disease (SCD) – may have involved the quality of the stem cells and not the conditioning regimen or characteristics of the patient at baseline. But researchers won’t know until more work is done.
Jasper Therapeutics Inc. may have found a way around toxicity with current approaches in sickle cell disease (SCD) conditioning approaches, if phase I/II data with briquilimab stay consistent – and the drug already has proved itself across a range of indications. Wall Street liked the prospect, sending the Redwood City, Calif.-based firm’s shares (NASDAQ:JSPR) on a wild ride to close at $2.74, up $2.26, or 476%.
The most common cause of anemia in chronically ill hospitalized patients is due to inflammatory anemia (IA) that is caused indirectly by diseases such as autoimmune, cancer, chronic kidney disease, congestive heart failure, or pulmonary disease. The precise and common etiology of these diseases involves hypercytokinemia that leads to excessive increases in hepcidin, a master regulator of iron homeostasis that blocks intestinal iron absorption when levels are too persistently high.
The primary reason for hospitalization of patients with sickle cell disease (SCD) is an acute systemic painful vaso-occlusive episode (VOE), which serves as an antecedent to acute chest syndrome (ACS). It has been previously demonstrated that P-selectin-dependent neutrophil-platelet aggregation and the complement pathway activation contribute to the vaso-occlusive pathophysiology in SCD.
Little more than a month after the U.S. FDA approved the first gene therapy for adults with hemophilia B, Uniqure NV’s Hemgenix, strong phase III data have come from Pfizer Inc. The Pfizer results show fidanacogene elaparvovec, a vector containing an AAV capsid and a high-activity human coagulation factor IX (FIX) gene for treating adult men with moderately severe to severe hemophilia B, hit the primary endpoint in the phase III Benegene-2 study. The one-time therapy is designed to allow those living with hemophilia B to be able to produce FIX instead of receiving regular, ongoing doses of exogenous FIX.
Lunac Therapeutics Ltd. has synthesized coagulation factor XII (FXIIa) inhibitors reported to be useful for the treatment of arthritis, Alzheimer's disease, disseminated intravascular coagulation, pulmonary embolism, myocardial infarction, diabetic retinopathy, stroke and deep venous thrombosis, among others.
CRISPR gene editing has been one of the important advances of the last decade, in biotechnology and increasingly in medicine. First applied to human cells in 2013, and honored with the 2020 Nobel Prize in Physiology or Medicine, its meteoric rise can make CRISPR look like the molecular equivalent of a miracle healer. But in the research and clinical trenches, CRISPR-based approaches, like any others, need to find applications where their desired effects outweigh their side effects. And finding those applications necessitates ways to identify off-target effects.
SLN-140 (Silence Therapeutics plc) is a novel small interfering RNA (siRNA) targeting protein S for the treatment of hemophilia A (HA). Researchers from the University of Bern recently presented data from studies conducted in animal models of HA, performed to evaluate the safety and efficacy of SLN-140.
New and updated clinical data presented by biopharma firms at the American Society of Hematology annual meeting and exposition, including: Amgen, Beigene, Novartis, Pharming.
