As platforms mature, personalised oral biologics are expected to expand into new clinical areas, strengthening market relevance.

• For instance, Chiasma evaluated oral octreotide capsules in a Phase 3 trial involving 155 patients to support personalised dosing outcomes in acromegaly treatment.

Key Challenges

Low Bioavailability and Physiological Barriers

Achieving reliable absorption of macromolecules remains a major scientific challenge. The gastrointestinal tract exposes molecules to enzymatic degradation, pH variation, and limited permeability. These conditions reduce bioavailability and demand complex protective technologies. Formulation success requires balancing stability, release control, and absorption enhancement. Overcoming these biological barriers increases development time and scientific risk.

High Development Costs and Regulatory Complexity

Developing oral biologics requires extensive clinical validation, high investment, and robust safety testing. Regulatory expectations demand strong evidence of efficacy, stability, and long-term safety, increasing trial duration and cost. Manufacturing standards add further complexity as production must ensure consistent molecule integrity. These challenges raise entry barriers and influence commercial decision-making.
