The foundational discovery of the toxic alpha-sheet structure was first identified via computer simulations because it was impossible to characterize experimentally. This computational hypothesis then required 15 years of wet lab work to validate, highlighting the power of in-silico methods to pioneer novel drug targets.
Alt-Pep's SOBA blood test is a crucial companion diagnostic for its SOBIN-AD therapeutic. It allows for patient stratification by confirming the presence of the drug's target—toxic oligomers. This creates a rare, direct link between biomarker, target, and mechanism, significantly increasing the probability of clinical success.
Instead of patenting a specific molecule, Alt-Pep underwent a decade-long process to patent the novel alpha-sheet protein structure itself. This unconventional IP strategy gives them a powerful, defensible platform applicable across numerous amyloid diseases, not just a single target composition.
Antibodies bind to specific amino acid sequences, making them unable to distinguish between a protein's healthy and toxic structural forms. Alt-Pep's synthetic peptides use a complementary structure (alpha-sheet) to selectively bind only the toxic oligomers, enabling both targeted therapy and highly specific diagnostics.
The long-term vision for Alt-Pep's diagnostic extends beyond symptomatic patients or those with family histories. The goal is for it to become a routine screening assay, administered annually to the general population to catch the disease at its earliest molecular stages, changing the paradigm from treatment to prevention.
Alt-Pep sees its core strength as early-stage science and development across a portfolio of amyloid diseases. The company's long-term plan is to focus on this R&D engine and partner with big pharma for late-stage development and commercialization, rather than building its own sales and marketing infrastructure.
