New single-step genome editing techniques that enable the insertion, inversion or deletion of long DNA sequences at specified genome positions have been demonstrated in bacteria. The advance opens the door to the development of programmable methods for rearranging DNA, using recombinase enzymes guided by RNA. The two different approaches to using insertion sequences (IS) – some of the simplest and most compact mobile genetic elements – are described in two papers published in Nature and Nature Communications.
Ending a late 2021 deal that was potentially worth billions, Moderna Inc. and Metagenomi Inc. are going their separate ways. The two had been collaborating on gene-editing R&D to develop therapies for treating serious genetic diseases. Moderna said it agreed with Metagenomi to end the deal as “Moderna continues to strategically prioritize its research and development investments.”
Seven years after embarking on in vivo therapeutic development using CRISPR/Cas gene-editing technology with Intellia Therapeutics Inc., Regeneron Pharmaceuticals Inc. is bringing another company into the collaborative fold. Regeneron will pay Mammoth Biosciences Inc. $100 million, including $95 million as an equity investment, and an up-front payment. Mammoth also could bring in up to $370 million for each target in milestones along with royalties on net sales from products created through the collaboration.
Beam Therapeutics Inc. has received clearance of its clinical trial authorization (CTA) application by the U.K.’s Medicines and Healthcare Products Regulatory Agency for BEAM-302, an in vivo base editor, as a potential treatment for patients with α1-antitrypsin deficiency (AATD).
An Italian group of researchers has used zinc finger editing to silence the PCSK9 gene and improve blood cholesterol levels in mice by applying a single dose of their modifier. The epigenetic-based method could be an alternative to genome editing.
Precision Biosciences Inc. has received pre-IND regulatory feedback from the FDA and ex-U.S. agencies providing alignment and clarity on Precision's final IND/CTA-enabling preclinical plans and clinical strategy for PBGENE-HBV.
Gene editing firm Metagenomi Inc. priced an IPO raising $93.8 million, while Telomir Pharmaceuticals Inc., a company developing small-molecule therapies targeting inflammatory disease, priced a more modest $7 million IPO. While they mark the second and third biopharma IPOs to price this week, and the sixth and seventh for 2024, the two aptly named companies are the first preclinical-stage ventures to test the public markets this year.
The Cystic Fibrosis Foundation (CF Foundation) has agreed to provide Prime Medicine Inc. with up to $15 million to support the development of prime editors for the treatment of cystic fibrosis (CF).
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.
