Brief Summary

A prospective, single-center, open-label, phase I study evaluating the pharmacokinetics (PK) of human parathyroid hormone (1-34) ("PTH") administered via the RaniPill™ capsule ("RT-102").

Detailed Description

The RaniPill device is a capsule-like ingestible device, which injects a microneedle containing a micro tablet (payload/drug) into the intestinal wall. This is a single-center, prospective, open-label, feasibility study being conducted in two parts.

Part 1: Healthy women volunteers, 18-65 years of age, of any race, recruited from the general population and assigned to one of the following groups:

RT-102:

* RT-102 Group 1: 20 µg (N=15)

* RT-102 Group 2: 80 µg (N=15)

Subcutaneous (SC):

• SC Group: 20 µg of Forteo (N=10)

Part 2: Healthy women, 18-65 years of age, or healthy post-menopausal or surgically sterile with bilateral oophorectomy women of any race, recruited from the general population will have once-a-day repeat dosing with 20 μg dose of RT-102 for 7 days (N= up to 12):

* Healthy women: N = up to 12

* Post-menopausal or surgically sterile volunteers: N = up to 7
