Advances lately in the genome-editing space include Beam Therapeutics Inc. publication in The CRISPR Journal details of its work with inlaid base editors, which the firm is applying in the BEAM-102 program for sickle cell disease. IBEs’ predictable, shifted editing window lets researchers go after disease-causing mutations that canonical base editors cannot reach, Beam said, and do the job with high efficiency and few off-target effects on the genome. The hottest news due in the near-term future from the sector will spill from Intellia Therapeutics Inc., of Cambridge, Mass., which is due to roll out first-in-human data with a systemic CRISPR-based genome editing therapy, NTLA-2001, in hereditary transthyretin amyloidosis.
In biotech and biopharma’s third-largest ever up-front development and commercialization deal, Crispr Therapeutics AG will receive an initial $900 million in an amended deal with Vertex Pharmaceuticals Inc. to lead the development, manufacturing and commercialization of gene editing therapy CTX-001 for sickle cell disease and transfusion-dependent beta-thalassemia.
Cambridge, Mass.-based Agios Therapeutics Inc.’s encouraging phase III data from a pair of trials with allosteric activator mitapivat in pyruvate kinase deficiency brought more attention to the space, where Rocket Pharmaceuticals Inc. – at a much earlier stage – is trying a gene therapy called RP-L301.
Just weeks after two unexpected cases of blood cancer landed trials of its investigational gene therapies for sickle cell disease (SCD) and beta-thalassemia on FDA-issued clinical holds, Bluebird Bio Inc. said it's talking to regulators about their resumption after what RBC analyst Luca Issi called a "partial exoneration" of the BB-305 lentiviral vector shared between the medicines.
Shares of Bluebird Bio Inc. (NASDAQ:BLUE) fell 37.8% to $28.44 on Feb. 16 as the company temporarily suspended two trials of its experimental gene therapy for sickle cell disease, Lentiglobin (BB-1111), while investigating one unexpected case of acute myeloid leukemia (AML) and another of myelodysplastic syndrome among participants in a phase I/II study of the candidate, called HGB-206. A second patient experienced MDS in 2018.
Veralox Therapeutics Inc., a Maryland-based startup developing a small molecule for halting aberrant platelet activation and thrombosis, said the FDA has granted the candidate, VLX-1005, orphan drug status for the treatment of heparin-induced thrombocytopenia (HIT).
At the recent 39th J.P. Morgan Healthcare Conference, Biomarin Pharmaceutical Inc. popped the lid off top-line results from its ongoing phase III GENEr8-1 study with valoctocogene roxaparvovec – also known as valrox, now commonly called Roctavian. Data, though encouraging, may not have quelled controversy around the prospect.
Imara Inc. reported a mixed bag of phase IIa study data for its lead candidate, IMR-687, for treating sickle cell disease in adults, bringing an end to a study that the company found cumbersome and that eventually stung its stock.
Amsterdam-based Uniqure NV’s regulatory hitch with its highly regarded hemophilia B program had analysts questioning during a conference call what the development might mean for the company’s deal with CSL Ltd.
