Linkcure Therapeutics has synthesized molecular glue degraders acting as zinc finger protein 803 (ZNF803; WIZ) degradation inducers reported to be useful for the treatment of sickle cell anemia and β-thalassemia.
Only a couple of years since the first sickle cell disease (SCD) gene therapies gained U.S. FDA approval, researchers are working to expand access for younger children, and to improve manufacturing and commercialization to reach patients faster.
Sickle cell disease (SCD) and transfusion-dependent β-thalassemia (TDT) are severe monogenic blood disorders caused by mutations in the β-globin gene (HBB), resulting in abnormal or insufficient production of adult hemoglobin (HbA). Among emerging therapeutic approaches, the reactivation of fetal hemoglobin (HbF) represents one of the most promising strategies for both conditions.
Enlaza Therapeutics Inc. will take charge of research through nominating candidates in its potentially $2 billion-plus deal with Vertex Pharmaceuticals Inc. For its efforts, Enlaza is getting $45 million in an up-front payment and equity investment, plus the opportunity to bring in more than $2 billion in research, development, regulatory and commercial milestones and tiered royalties on net sales.

Yoltech Therapeutics Co. Ltd. has advanced YOLT-204 into the clinic for the treatment of transfusion-dependent β-thalassemia (TDT). If successful, YOLT-204 may provide an off-the-shelf curative treatment for TDT patients without conditioning chemotherapy and hematopoietic stem cell transplantation.
Editas Medicine Inc. has achieved in vivo preclinical proof of concept of hematopoietic stem and progenitor cell (HSPC) editing and fetal hemoglobin (HbF) induction in humanized mice engrafted with human hematopoietic stem cells and lacking their own hematopoietic cells.
The U.S. Department of Health and Human Services’ Office of the Inspector General disclosed an advisory opinion finding Bluebird Bio Inc.’s fertility support program for a gene therapy treatment could run afoul of federal anti-kickback statutes. That follows a similar opinion against Vertex Pharmaceuticals Inc., and its fertility program associated with gene-editing therapy Casgevy (exagamglogene autotemcel). Vertex subsequently filed a lawsuit.
Transmembrane serine protease 6 (TMPRSS6) is a negative regulator of hepcidin, which is the main iron homeostasis-regulating hormone. Regeneron Pharmaceuticals Inc. has recently presented preclinical data for the monoclonal antibody targeting TMPRSS6, REGN-7999, which is being developed for the treatment of iron overload.
Though the PDUFA date for its BLA wasn’t until March 30, 2024, Vertex Pharmaceuticals Inc. celebrated the U.S. FDA approval Jan. 16 for Casgevy (exagamglogene autotemcel), expanding use the CRISPR/Cas9 gene-edited cell therapy in patients, 12 and older, with transfusion-dependent beta-thalassemia.
