Cyclic peptides open new drug frontiers, if manufacturing can keep up

With oral cyclic peptides offering small molecule convenience and antibody‑like selectivity, the modality is gaining momentum. But bioavailability below 1%, minimal PK data and fragile synthesis still slow progress. Viva Biotech’s experts outlined how hybrid synthesis, ADME/PK modeling and AI‑guided design are expanding what peptide therapeutics can reach.
