Haya's approach redefines the drug target. Instead of focusing on single proteins or pathways, they identify the "causal unit" of disease as the cellular behaviors that dictate how patients feel, function, and survive, and then work backwards to find a target.
Instead of the traditional lab-to-clinic pipeline, a "reverse translation" approach uses AI to analyze data from patients who fail standard-of-care treatments. This identifies the specific unmet need and biological target first, guiding subsequent lab research for higher success rates.
The company focuses on disease-specific 3D protein conformations, which exposes new binding sites (epitopes) not present on the same protein in healthy cells. This allows for highly selective drugs that avoid the toxicity common with targets defined by genetic sequence alone.
The discovery-based model of finding highly impactful single targets like HER2 or PD-1 is becoming unsustainable as the low-hanging fruit is picked. The field must shift toward an engineering-first approach, designing complex, multi-functional therapeutics to achieve specific clinical objectives, much like high-tech fields.
Instead of the traditional 'disease-target-drug' approach, Soleil finds compounds that create a desired cellular change first. Only after identifying a promising, well-tolerated molecule with a known cellular mechanism do they use bioinformatics to determine which disease and patient population it's best suited for.
Coya Therapeutics is pursuing a novel therapeutic goal for ALS: making the condition "livable" by stopping its progression. Instead of aiming for a cure or reversing existing damage, their strategy focuses on preserving a patient's current motor function, which would represent a significant breakthrough in managing the neurodegenerative disease.
Instead of creating therapies for hundreds of specific driver mutations, which vary widely between patients, Earli's platform targets downstream commonalities—the "hallmarks of cancer" like rapid cell proliferation. These pathways are where diverse mutations converge, creating a more universal and reliable target across different cancers.
The ultimate vision is to move beyond generalized treatments to truly individualized medicine. This involves understanding the complete causal chain from a person's unique genetic variants to the resulting protein behavior and disease. With this mechanistic understanding, it becomes possible to design a bespoke drug for that specific individual.
Medicine is shifting from a 200-year-old paradigm of using chemical drugs to block symptoms toward a new era of cell and gene therapies. This new approach fundamentally changes treatment by directly addressing the root cause of disease: repairing or replacing the faulty cells and genes themselves.
Haya's AI platform is differentiated by its focus on deconvoluting the "dark genome" to identify completely novel, "first-in-biology" targets. This contrasts with AI applications that merely optimize molecules for known biological pathways or targets.
Soleil moves beyond the single-target model by mapping the entire flow of information a drug creates within a cell. They argue that even approved drugs have 30-40 other effects. By understanding the global cellular response from day one, they aim to better predict both efficacy and toxicity, addressing a key failure point in traditional discovery.
