GPR75

On July 26, Belgian biotech company Confo Therapeutics (Confo) announced that it has completed a €60 million Series B financing round. This round was led by Ackermans & van Haaren (AvH), and received participation from new investors Driehaus Capital Management and Quest for Growth (QfG), alongside existing investors BioGeneration Ventures (BGV), Capricorn Health-tech Fund (CHF), Fund+, MINTS, Perceptive Advisors, Qbic, PMV, V-Bio Ventures, VIB, and Wellington Partners. The funding will be used to advance two wholly owned projects into Phase I clinical trials, and move two other projects to the Investigational New Drug (IND) approval stage, including the GPR75 target molecule for obesity. Confo is a platform-based biotech company focused on the discovery and development of GPCR class drug targets. At the beginning of 2023, Confo announced a global licensing agreement with Eli Lilly on the clinical treatment of neuropathic pain related to their investigational drug CFTX-1554 and alternative compounds, jointly advancing the AT2R antagonist drug. The current status of the company's pipeline is as follows: Confo Therapeutics is a Belgian company specializing in new drug discovery on GPCR family targets. The company possesses a proprietary drug discovery engine (accurately locking in the required GPCR conformation using nanobodies), this unique ability allows Confo to tap into vast untapped potentialities, discovering and developing breakthrough drugs. The company's main technology route is as follows: ConfoBody can stably keep GPCR in its active conformation, thereby increasing the chances of identifying ligands with conformational selectivity. For example, the active state-specific ConfoBody can stabilize the agonist-GPCR complex, enhancing sensitivity to the agonist. The proprietary ConfoScreen method has a high sensitivity, capable of identifying smaller chemical starting points, including compound fragments with a molecular weight of <300 MW. By developing ConfoBody that specifically recognizes receptors, on one hand, it can stabilize the conformation of the receptor in the expected state, on the other hand, some nanobodies can also stabilize the receptor-G protein (mainly Gs subtype) complex. The company has obtained the exclusive license for MegaBody™ technology, which is a new scaffold based on ConfoBody. It retains the conformational selectivity of the parent ConfoBody, while providing more mass and structural features for high-resolution cryo-electron microscopy. MegaBodies™ are able to capture protein conformations, influence particle orientation, serve as a handle for three-dimensional image reconstruction, and increase the size of protein complexes, thus making GPCR more suitable for study through cryo-electron microscopy. With ConfoStructures, a method based on structure-based drug design is used to quickly and efficiently improve µM chemical starting points into nM affinity lead compounds, and endow them with excellent drug-like characteristics.

Founded nearly a decade ago to develop GPCR-targeting drugs, Confo Therapeutics has found itself in a prime position as the industry-wide weight-loss craze — driven by GPCR family member, GLP-1— reaches new heights. The Belgium-based biotech raised €60 million ($65.1 million) in a series B financing Friday to advance its GPR75-targeting obesity candidate along with three others in the endocrine and metabolic disease space. Confo isn’t sharing much about the other programmes it’s progressing, but the funds will advance two through Phase I testing, and help another pair ready for IND. According to the company’s website, it has a mix of antibodies and small molecules in development for conditions such as hyperparathyroidism, hyperinsulinemia, and fibrotic diseases.The firm also has an AT2R-targeting peripheral pain candidate in a Phase I trial. Eli Lilly paid $40 million upfront last year to gain rights to that therapy, and is on the hook for $590 million more in milestones.GPCR stabilisationWhile Confo’s pipeline may seem wide-reaching, that’s only because GPCRs “play a role in almost any disease you can think of,” CEO Cedric Ververken told FirstWord, naming asthma and diabetes, as well as central nervous system and cardiovascular disorders. Despite the strong scientific rationale behind modulating GPCRs for various diseases, there are hundreds of receptors that have yet to be successfully targeted. That’s due to two factors, Ververken explained: the proteins are deeply embedded in the cell membrane, and they’re conformationally unstable, making them difficult to study. That’s where the ConfoBodies platform comes in. The company has developed a suite of tool antibodies to stabilise GPCR proteins in their therapeutically relevant conformation, enabling increased screening sensitivity for drug discovery.The technology is so powerful, Ververken said, that Confo can pick up on fragments, which are “really tiny chemical starting points” that wouldn’t be detected in a normal signalling assay. “Starting from something that small allows us to build up these drugs in a very efficient way without built-in toxicophores or lipophilic parts,” he added. “We can really maintain favourable drug-like properties from the start.” Plus, Confo isn’t limited to small molecules. The company also boasts a therapeutic antibody generation platform geared specifically towards agonists, “which is quite a unique feat in the industry,” Ververken said.There are three GPCR-targeted antibodies on the market, but none are agonists. Confo’s agonist antibody capabilities are part of what’s helped the firm to attract deals with Regeneron and AbCellera, he added. All systems go on obesityFor its internal pipeline, Confo is initially focusing on endocrine and metabolic diseases because there’s a wealth of biologically relevant GPCRs in that space — with GLP-1 as a prime example. Plus, the pharmacology of these particular receptors is well-established, making therapeutic activity easier to confirm in Phase I healthy volunteer studies, Ververken said. From there, it’s a straightforward path to clinical proof-of-concept.The space also has a healthy mix of rare disease opportunities that can be tackled by a small biotech, as well as big indications like obesity that are attractive to pharma. “It allows us to build a pipeline towards an IPO, but it also allows us to work on projects that could potentially drive an M&A deal at some point,” Ververken commented. Obesity is where Confo is planning on allocating the majority of its resources as it races to be first in the clinic with its GPR75 agonist, he added. The target was first linked to obesity in 2021 when a genetic study showed that individuals with a loss-of-function mutation in the gene had a lower risk of obesity and improvements in certain metabolic measures that suggested the protein played a role in muscle-mass preservation.  That muscle benefit falls squarely within the next-generation weight-loss drug wish list, along with improved tolerability.
