Osteoanabolic agents, like teriparatide and abaloparatide, are not only effective in reducing fracture incidence but also improve skeletal microstructure; an important challenge not met by antiresorptive agents. However, anabolic agents must be administered by daily subcutaneous injections which can be a challenge in older women. To address this need, we have developed an oral robotic pill (RP) designed to deliver biotherapeutics safely and painlessly. Methods: This report describes the results of a two-part Phase 1 study conducted to evaluate the safety, tolerability and pharmacokinetics (PK) of single (Part 1) and repeat doses (Part 2) of teriparatide delivered via the RP (RT-102) in healthy and post-menopausal women. Results: All participants were able to swallow RT-102 without any difficulty. Teriparatide, administered by the RP, was measurable in the circulation of 90% (26/29) and 91% (63/69) of participants in Part 1 and Part 2, respectively. Doses of teriparatide administered via RP yielded higher estimated bioavailability than SC. RT-102 was well tolerated without any SAEs. Drug-related adverse events were similar in severity and frequency between RT-102 and teriparatide SC. Conclusion: These data demonstrate that RT-102 can safely and reliably deliver therapeutic levels of teriparatide.
