Researchers from Beam Therapeutics Inc. presented the discovery and preclinical evaluation of an engineered stem cell antibody paired evasion (ESCAPE) strategy for antibody (Ab)-mediated autologous hematopoietic stem cell (HSC) therapy conditioning for the treatment of hemoglobinopathies.
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 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.
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.
CRISPR-based cell therapies continued to gain steam Sept. 27 with the announcements of a potentially valuable big pharma collaboration and an ambitious global regulatory push.
Shares in Forma Therapeutics Holdings Inc. gained 51% as Novo Nordisk A/S made a $20-per-share offer that values the firm’s equity at $1.1 billion. The stock (NASDA:FMTX) had closed at $13.40 prior to the disclosure of the bid on Sept. 1. It closed the day at $20.24, up $6.84, suggesting at least some optimistic investors believe the final price could go higher.
Bluebird Bio Inc. isn’t giving out much of the information on the margins for the cost of its newly approved cell-based gene therapy for treating adult and pediatric patients with beta-thalassemia. The numbers will, the company said, come into better focus when another Bluebird drug is approved and launched.
The U.S. FDA has approved the first cell-based gene therapy for treating adult and pediatric patients with beta-thalassemia requiring frequent red blood cell transfusions. The $2.8 million wholesale acquisition cost for the one-time I.V. infusion will make it one of the most expensive drugs in the U.S.
Pfizer Inc. plans to pay about $5.8 billion – total equity value – for Global Blood Therapeutics Inc. (GBT) and its oral sickle cell disease (SCD) treatment Oxbryta (voxelotor). The company reported the enterprise value as $5.4 billion, which includes debt and net cash. If completed, the GBT buy would be the second largest M&A in 2022 after Pfizer’s $6.7 billion buyout of Arena Pharmaceuticals Inc. Oxbryta, which netted about $195 million in sales in 2021, gained U.S. FDA approval in November 2019 for the treatment of SCD in adults and pediatric patients ages 12 and up. The FDA later expanded Oxbryta’s approved uses to SCD patients 4 years of age and older in December 2021.
