So the system moves fast. Launches hard. And waits to deal
               with tolerization after the revenue curve has already
               peaked.


               This is not a flaw in the science.
               It’s a flaw in what the system chooses to value.

               And until immune durability becomes a metric that matters
               before approval, not after, the cycle will continue: build,
               launch, escalate, switch.
               A business model built on biological failure.


               Designing for tolerance means more complexity, more
               uncertainty, and more time.
               It’s not a tweak—it’s a redesign. A foundational shift in
               how we think about the relationship between the drug and
               the immune system from the first day of development, not
               the last.


               It means investing in preclinical models that don’t just ask,
               does this drug bind the right target?—but also, will the
               immune system learn to live with it? That means building
               animal studies and in vitro assays that capture T cell
               activation, ADA formation risk, mucosal exposure
               dynamics, and early signs of immune rejection. These
               aren’t industry standard today—not because they don’t
               work, but because they aren’t required.


               It means designing delivery platforms that mimic how the
               body naturally encounters and accepts proteins: through the
               gut, across mucosal tissues, or in repeated low-dose
               exposures. That runs counter to the dominant model of
               infrequent, high-concentration injections. Oral tolerance
               strategies, mucosal immunization pathways, nanoparticle
               carriers—these are tools that teach the immune system
