Blood treatments utilizing gene therapy advance through medical facilities
In the realm of medical breakthroughs, gene therapy is making significant strides in treating blood disorders such as hemophilia and sickle cell disease. Here's a roundup of the latest developments from key players in the field, including uniQure, Freeline, Aruvant Sciences, and CRISPR Therapeutics.
General Advancements
Researchers have developed a novel gene-editing method called "delete-to-recruit," which uses CRISPR-Cas9 to reactivate dormant genes by moving them closer to enhancers. This approach shows promise for treating sickle cell disease by potentially restoring gene function without introducing foreign genetic material[1]. Additionally, the first potentially curative gene therapies for sickle cell disease have been approved by the FDA, although they come with significant logistical challenges and risks[5].
Blood disorders are finding a revolutionary solution in gene editing, offering new hope for patients[4].
Specific Companies
While uniQure, Freeline, Aruvant Sciences, and CRISPR Therapeutics are all making strides in gene therapy, specific updates on their recent progress vary.
uniQure, known for its work in gene therapy, has been involved in treating hemophilia B with its gene therapy candidate. In a phase I/II trial for hemophilia B, uniQure's therapy showed positive results at the 2018 annual meeting of the American Society of Hematology[6]. The company is also developing gene therapies for other diseases such as Huntingdon's disease and is conducting a phase IIa trial for another gene therapy in three patients with hemophilia B, who have shown no bleeding nor need for synthetic factor IX protein[8].
Freeline, another gene therapy player, is active in hemophilia and other genetic disorders. The company's CEO, Anne Prener, stated that Freeline's therapy is designed to provide a functional cure for hemophilia B patients[9]. In an ongoing phase I/II trial, Freeline's hemophilia B gene therapy candidate showed good results, completely stopping bleeds and the need for synthetic factor IX in two patients by nine months after injection[7].
Aruvant Sciences focuses on gene therapy for hemoglobinopathies, including sickle cell disease. In its clinical trial, the treatment reduced blood clots and increased the amount of healthy hemoglobin in the patients for over one year[2]. The company's treatment modifies the patient's blood stem cells to express fetal hemoglobin and grafts them into the bone marrow.
CRISPR Therapeutics has been making significant strides in gene editing for various diseases. While there is no direct mention of its work on hemophilia or sickle cell disease in the search results, CRISPR Therapeutics reported early results from its first in vivo gene editing trial for heart disease, targeting the ANGPTL3 gene and showing promising reductions in triglycerides and LDL cholesterol[3]. The company is running a phase I/II trial of its CRISPR technique to treat sickle cell disease in collaboration with Vertex Pharmaceuticals.
Future Outlook
The future of gene therapy for blood disorders holds much promise. As more companies continue to develop innovative treatments, the challenge will be in overcoming the logistical and safety hurdles associated with these therapies to make them more accessible to patients.
People with hemophilia B, deficient in the blood-clotting protein factor IX, experienced almost no bleeds after uniQure's gene therapy[6]. Freeline's hemophilia B gene therapy candidate showed good results in an ongoing phase I/II trial, completely stopping bleeds and the need for synthetic factor IX in two patients by nine months after injection[7]. Aruvant's treatment had positive effects in two patients with sickle cell disease in an ongoing phase I/II trial[2].
Some companies, such as CRISPR Therapeutics, are turning to the gene-editing technique CRISPR-Cas9 as a tool for fighting blood disorders like sickle cell disease. Gene therapy shows promising results in treating blood disorders such as hemophilia and sickle cell disease, and is becoming a big market.
