Spatial microbiome mapping technologies identify tissue-specific bacterial communities, enabling targeted therapeutic development for conditions like colorectal cancer where tumor-adjacent microbiomes differ significantly from healthy tissue.

What are the major scientific and regulatory challenges that remain unsolved?

Mechanistic causality represents the biggest scientific hurdle, as distinguishing disease-causing dysbiosis from beneficial compensatory changes requires longitudinal multi-omics studies spanning years.

Current research cannot definitively prove whether observed microbiome alterations cause disease or result from it, creating risks of correcting beneficial adaptive changes. Clinical endpoint standardization lacks consensus across indications, with regulatory agencies requiring clinically meaningful outcomes rather than just microbiome composition changes.

Manufacturing challenges for anaerobic bacterial strains demand bespoke CDMO processes, with viability during scale-up remaining problematic and costs often exceeding $500 per dose for complex consortia. Regulatory pathways for "bugs-as-drugs" remain unclear, as each live biotherapeutic requires unique safety and efficacy demonstrations without established precedents.

IP protection limitations arise because natural bacterial strains cannot be patented, forcing companies to rely on composition-of-matter patents for engineered strains or method-of-use patents that offer weaker protection. These challenges are unlikely to be fully resolved before 2027, requiring companies to build robust scientific foundations while navigating evolving regulatory frameworks.
