Multi-specific antibodies promise to unlock complex biology that conventional monoclonals can’t touch, but their added mechanisms of action also introduce safety and developability risks. These antibodies—especially T‑cell engagers—behave differently from traditional monospecific antibodies, and seemingly minor architectural tweaks can cause disproportionate shifts in potency, selectivity, and cytokine release. LabGenius is trying to turn multi-specific design from an intuition-driven art into a genuine engineering discipline by generating proprietary data at scale and feeding them back into machine learning models. Angus Sinclair, chief scientific officer of LabGenius, discusses why many safety failures in early solid-tumor T‑cell engagers were effectively locked in at design, how the company’s AI platform engineers multi-specific T‑cell engagers that are both potent and selective in solid tumors, and where AI is actually adding value in multi-specific design today.

Acute ischemic stroke is both ubiquitous and undertreated. Only a small fraction of patients currently receive clot-busting drugs or mechanical thrombectomy because of the small treatment window. That’s because existing therapies require rapid presentation to specialized centers and carry nonreversible bleeding risks that make clinicians hesitant to use them. Basking Biosciences is developing a first-in-class, reversible thrombolytic that targets von Willebrand factor to expand access to safe, effective treatment. Basking Biosciences CEO Julia Owens and co-founder and chief scientific officer Shahid Nimjee discuss the tension between restoring blood flow and causing irreversible intracranial hemorrhage that clinicians face in treating ischemic stroke, the narrow treatment window for existing therapies, and how modulating von Willebrand factor may open a much larger treatment window across a broader range of care settings.

Plasma gelsolin is an abundant, endogenous regulator of inflammation that is consumed during severe inflammatory insults. When levels fall too low, patients are at higher risk of organ damage and death, particularly in settings like acute respiratory distress syndrome where a dysregulated inflammatory response floods the lungs with fluid and leaves patients dependent on ventilatory support with no approved therapies today. BioAegis Therapeutics is working to turn recombinant human plasma gelsolin into a pipeline-in-a-product. Susan Levinson, CEO of BioAegis, discusses recombinant human plasma gelsolin as a potential first-in-class treatment for ARDS and other inflammasome-driven conditions, how it modulates cytokine storms without suppressing the immune system, and its potential in other conditions including neurodegenerative diseases.
