STAT+: Researchers behind GLP-1 obesity drugs advance new approach: Drop GLP-1 as a target
The scientists whose work spurred the development of powerful obesity drugs like Eli Lilly’s Zepbound are now raising a provocative hypothesis: Perhaps targeting the GLP-1 hormone is actually not necessary to achieve effective weight loss.
A group of researchers led by Richard DiMarchi and Matthias Tschöp has created an experimental drug that activates receptors of the GIP and glucagon hormones. They propose — based on rodent and monkey studies — that this kind of molecule, when administered at high enough doses, may result in weight loss comparable to the weight loss seen with drugs that include GLP-1 as a target, and without the tolerability issues like nausea and vomiting that often come with the approved treatments, according to a peer-reviewed draft paper published this week.
The research, funded by a biotech called BlueWater Biosciences, would still need to be confirmed in humans; oftentimes results seen in animals don’t translate in the clinic. But the proposed approach, outlined in the journal Molecular Metabolism by some of the most well-known scientists in the field, is likely to stir controversy, as it challenges a central notion underpinning not just the development of approved obesity products but also next-generation versions.

Biotechnology company SonoThera has raised $125 million in an oversubscribed Series B financing round. The financing was led by Vida Ventures, with participation from ARK Invest, CureDuchenne Ventures, Leaps by Bayer, Otsuka Pharmaceutical, SymBiosis, UCB Ventures SA, Vivo Capital, and existing investors ARCH Venture Partners, Alexandria Venture Investments, Duquesne Family Office, Illumina Ventures, Johnson & Johnson Innovation – JJDC, Medical Excellence Capital, RA Capital, and Vertex Ventures HC.
SonoThera will use the funds to advance its lead programs in Duchenne muscular dystrophy (DMD) and autosomal dominant polycystic kidney disease (ADPKD) in the clinic. The funds will also support efforts to expand its pipeline of targeted redosable genetic medicines across multiple organ systems and scale its proprietary platform technologies for safe, targeted therapy delivery.
The company’s platform combines a proprietary ultrasound-mediated delivery technology dubbed RIPPLE
, with a payload engineering platform dubbed PORE. The platforms are designed to support the development of DNA and RNA therapeutics, gene editing, and gene silencing approaches. SonoThera is using its tech to develop genetic medicines that it claims will address key limitations of conventional gene therapies including delivery challenges, payload size constraints, immune responses, safety events, and difficulties with redosing.
As Kenneth Greenberd, PhD, SonoThera’s co-founder and CEO, stated “we founded SonoThera to take a fundamentally different approach, with a platform designed to broaden the therapeutic possibilities of the field. We believe our technology has the potential to expand the range of diseases addressable by genetic medicines while enabling more precise, durable, safer, and repeatable therapies for patients.”
SonoThera has already demonstrated the targeted delivery and expression capabilities of its platform across multiple tissues, including skeletal muscle, heart, liver, kidney, adipose, and brain. It has also shown that it can deliver large payloads such as full-length dystrophin for DMD and RNA-based payloads for gene silencing applications in preclinical studies.
The company expects to initiate its first clinical trial in DMD in 2027.
Commenting on the financing, Rajul Jain, MD, managing director at Vida Ventures, said “we believe SonoThera, with its RIPPLE delivery and PORE payload engineering technologies, has the potential to unlock opportunities in diseases with significant unmet need that have been previously inaccessible to other genetic medicine approaches.”
In connection with the financing, Jain and Rakhshita Dhar, MS, vice president & head of Healthcare Venture Investments at Leaps by Bayer, have joined SonoThera’s Board of Directors.

Hired someone new and exciting? Promoted a rising star? Finally solved that hard-to-fill spot? Share the news with us, and we’ll share it with others. That’s right. Send us your changes, and we’ll find a home for them. Don’t be shy. Everyone wants to know who is coming and going.
And here is our regular feature in which we highlight a different person each week. This time around, we note that AstronauTx hired Michelle Mellion as chief medical officer. Previously, she held the same role at PepGen and EveryONE Medicines.
But all work and no play can make for a dull chief medical officer.
