UC Berkeley spinout raises $100 million for gene-therapy approach that ‘unlocks a world of possibility’

A spinout from the labs of University of California, Berkeley, professor Kathleen Collins and the campus' Bakar Bio Labs incubator, Addition is working on a different way to package and deliver long-lasting, life-changing "genomic medicines." Addition's team, now numbering 50, "spent four years with our heads down on the science, and we're feeling good," Park said. "It's a good base to talk to people externally, unstuffing." The technology is one thing, but there's another thing that's got Park excited about Addition: the big picture. Addition's approach opens the possibility of delivering one-shot-and-done therapies or redosing therapies for less. Read post

Addition Tx does the math and emerges from stealth with $100M, biotech vets on exec team

It’s early days for the startup, but its core tech is centered on its all-RNA, nonviral, lipid nanoparticle-based PRINT (Precise RNA Mediated Insertion of Transgenes) platform. The idea is to create “safer, durable, one-time therapies, overcoming limitations of current genetic medicine modalities,” the biotech said in a Dec. 17 statement. Details on disease targets are thin on the ground, but Addition says it is seeking to “redefine how chronic and rare diseases are treated.” Initial preclinical work is slated to begin next year. One area of work Addition has already spotlighted is HIV. Using a Gates Foundation grant, Addition will use one of its so-called PRINTed programs that aim, with a single dose, to allow endogenous production of antibodies to “provide lifetime protection against HIV.” Read post

Small Molecules to Correct a Rare Kidney Disease: Emily Conley on the Long Run

The big idea at Renasant is to develop oral small molecule drugs to treat patients with autosomal dominant polycystic kidney disease, known as ADPKD. Patients with this disease develop cysts on their kidneys that sometimes cause the kidney to balloon in size and grow into 30-pound dysfunctional, painful and swollen organs. Scientists think there’s a way to stop it. Renasant is developing small molecule correctors and potentiators that target the polycystin protein abnormalities that drive the disease. If the drugs work as conceived, they would enable people to avoid the grim fate of kidney dialysis or transplant. An estimated 300,000 patients in the US and Europe have the disease, which technically makes it rare, but not that rare. Read post

Azalea Therapeutics Presents New Preclinical Data Demonstrating Robust In Vivo Generation of TRAC-CAR T Cells Using Enveloped Delivery Vehicles

Azalea’s dual-vector platform combines T cell-targeted EDVs delivering Cas9 RNP complexes with a human T cell-tropic AAV carrying a promoterless CAR template. This approach enables precise genomic insertion at the TRAC locus, bringing CAR expression under the control of the native T cell receptor promoter. In vivo TRAC insertion is designed to improve potency, persistence and safety by achieving regulated, physiologic CAR expression rather than continuous signaling from exogenous promoters. Read post

East Bay AI biotech company raises $106 million from Jeff Bezos and others

Profluent Bio, a three-year-old Emeryville company, was the first to show that large language models can generate functional proteins. It went on to design the first CRISPR genome-editing system from scratch, creating an open-source gene editor known as OpenCRISPR-1. With its new-found cash from Altimeter and Bezos Expeditions, it now hopes to continue applying its genome editors into antibodies, enzymes and immune system-triggering antigens. It already has cut deals with a handful of partners, such as life sciences tools company Revvity Inc. (NYSE: RVTY) — the former PerkinsElmer Inc. — agricultural player Corteva Inc. (NYSE: CTVA) and the Rett Syndrome Research Trust, to make custom proteins. Read post

Jennifer Doudna spinoff aims to turn patients’ immune cells into CAR-T fighters with single shot

A spinout from the lab of Nobel laureate Jennifer Doudna has raised $82 million to create drugs that, with a single infusion, can turn patients’ immune cells into cancer- and autoimmune disease-fighting drones. It’s the latest entrant in a high-stakes race to develop what’s known scientifically as in vivo CAR-T treatments. Today’s CAR-T therapies are highly effective at treating certain blood cancers, but patients’ cells have to be removed, reengineered in a facility, and then reinfused — a toxic, expensive, and cumbersome process. Investors and pharma companies are spending billions to create alternatives that transform patients’ cells in their body. Read post

Why Jennifer Doudna, Reed Jobs and others are backing this East Bay biotech’s in-body cell fix-it shop

Azalea's approach is what scientists call in vivo — or in the living body — reprogramming of immune cells. That is one of the hottest areas of cell therapy research because it could make today's chimeric antigen receptor-T cell, or CAR-T, therapies safer, more efficient and more effective. Additionally, having the body's own cellular machine shop serve as a production line for infection-fighting T cells could shave weeks off the process of manufacturing therapies outside the body.

‘We want to change the world:’ Company says it is creating a new kind of plastic

FutureBio is tackling the problem of plastic pollution head-on by creating what its co-founder describes as a new kind of plastic. Different from both the petroleum-based and the biodegradable ones now in use, it is not only durable but also bio-renewable and easier to recycle, said Zilong Wang. “It proposes a different and a novel plastic, which is different from all other kinds of plastic,” he said. Worldwide, only about 9% of today's plastic is actually recycled. Most of the rest, millions of tons, goes to landfills or ends up in the environment. Even the plastic that is recycled is sent to landfills or incinerators after one or two cycles because the quality of the material degrades. Read post
