Lycia Therapeutics Inc. has reported progress in its immunology pipeline that comprises lysosomal targeting chimera (LYTAC)-based protein degradation therapies. The company is advancing its two lead programs toward the clinic: LCA-0061, a Catalytac degrader that catalytically degrades IgE, and LCA-0321, a Lytac degrader designed to specifically bind and rapidly deplete anti-thyroid-stimulating hormone receptor (TSHR) autoantibodies.
The 2022 Nobel Prize in chemistry was awarded to Carolyn Bertozzi of Stanford University, to Morten Meldal of the University of Copenhagen, and – for the second time – to Barry Sharpless of The Scripps Research Institute “for the development of click chemistry and bioorthogonal
chemistry.”
Click chemistry, the Nobel Committee’s Olof Ramström told reporters while announcing the prize, “is almost like it sounds – it’s all about linking different molecules.”
He likened click chemistry to a seatbelt buckle, whose interlocking parts can be attached to many different materials, linking them by snapping the two parts of the buckle together.
“The problem was to find good chemical buckles,” Ramström said – chemicals that “will easily snap together, and importantly, they won’t snap with anything else.”
Avilar Therapeutics Inc. emerged from stealth with a $60 million seed round and plans to apply a targeted protein degradation technology to a large swath of extracellular proteins associated with disease.
Eli Lilly and Co. tapped Lycia Therapeutics Inc. in a potential $1.6 billion-plus protein-degradation deal that brings $35 million up front and the remainder in would-be preclinical, development and commercial milestone payments, along with mid-single to low double-digit royalties. The multiyear research tie-up and licensing agreement strives to discover, develop and commercialize targeted therapeutics based on Lycia's lysosomal targeting chimera, or Lytac, technology.
LONDON – Targeted protein degradation (TPD) specialist Amphista Therapeutics Ltd. has delivered yet another demonstration of investor interest in the field, closing a $53 million series B.
In a BIO Digital session on “The Convergence of Health and Tech: Personalizing Medicine Beyond the Imaginable,” panelist Ray Deshaies, Amgen Inc.’s senior vice president of global research, said he was excited for the future of drug research, noting that there is an evolving trend away from the development of monospecific drugs designed to exert their effect on just one specific target.
DUBLIN – Lycia Therapeutics Inc. raised $50 million in series A funding from founding investor Versant Ventures to take forward yet another novel concept in targeted protein degradation. The new company, which will be headquartered in the San Francisco Bay Area, is building on the work of Carolyn Bertozzi, professor of chemistry at Stanford University and Howard Hughes Medical Institute (HHMI) investigator, who has invented bifunctional structures called Lytacs – lysosomal targeting chimeras – which target extracellular or circulating proteins for internalization and lysosomal degradation by tethering them to lysosome targeting receptors at the cell surface.
