Spotlight Therapeutics Inc., a company developing cell-targeted in vivo CRISPR gene editing biologics, has raised $36.5 million in series B financing to support advancement of its first-in-class immuno-oncology program and further applications of its in-house technology platform. The financing round was co-led by new investors GordonMD Global Investments and Epiq Capital Group, with participation from Magnetic Ventures, as well as existing investors GV, Emerson Collective and others.

LONDON – In the largest-ever series A for a Spanish biotech, Splicebio S.L. has raised €50 million (US$56.9 million) to apply its protein splicing technology to the delivery of large genes that do not fit into existing vectors. The company claims its approach will overcome the capacity constraints of adeno-associated viral vectors (AAVs), by splitting genes into parcels and reconstituting the proteins they express in vivo.

Sio Gene Therapies Inc. is retrenching the business as it terminated the company’s AXO-Lenti-PD license agreement with Oxford Biomedica plc for treating Parkinson’s disease. Also, Sio’s CEO, Pavan Cheruvu, is leaving the company.

Having unveiled more data from the ongoing, global phase III Gener8-1 study with Roctavian (valoctocogene roxaparvovec, also known as valrox), Biomarin Pharmaceutical Inc. remains on track to file a regulatory submission with the FDA in the second quarter of this year for the gene therapy to treat adults with severe hemophilia A. The EMA is already reviewing a marketing authorization application.

A raft of potentially high-value drug development collaborations, most for gene and RNA therapies, led the first day of the 40th Annual J.P. Morgan Healthcare Conference Monday. Pfizer Inc. enlisted Beam Therapeutic Inc. to advance in vivo base editing programs for up to $1.35 billion, while Bayer AG tapped Mammoth Biosciences Inc.’s in vivo CRISPR systems expertise in a potential $1 billion-plus deal. Selecta Biosciences Inc. inked a new $1.1 billion partnership with Ginkgo Bioworks Inc. to develop next-generation gene therapy capsids, while Acadia Pharmaceuticals Inc. agreed to pay Stoke Therapeutics Inc. as much as $967 million to develop RNA-based medicines. Work on new mRNA vaccines and therapies is also proceeding, with both Pfizer and Biontech SE announcing new collaborations in the space.

Avrobio Inc., stung by variable outcomes in a phase II test of its investigational Fabry disease therapy, is quitting further enrollment in the program, one of the first from its gene therapy platform, Plato. The team's attention will shift instead to other clinical-stage lysosomal disorder programs amid "an increasingly challenging market and regulatory environment for Fabry disease," the company said.
