3. Body mass index (BMI) ≥ 18.0 and ≤ 32.0 kg/m2 at screening.

4. Medically healthy with no clinically significant medical condition, physical examination, laboratory profiles, vital signs, orthostatic vital sign measurements, or ECGs, as deemed by the PI or designee to be relevant to the study and does not pose an additional risk to the subject by their participation in the study.

5. Understands the study procedures described in the Informed Consent Form (ICF), be willing and able to comply with the protocol, and provides written consent.

Exclusion Criteria

3. Any conditions or factors that, in the judgment of the PI or designee, somehow may impact gastrointestinal absorption, distribution or metabolism of parathyroid hormone analogues, or known to potentiate or predispose to undesired effects.

4. History of significant gastrointestinal, liver or kidney disease, or gastrointestinal surgery (including bariatric surgery, or any other interventional procedures with stomach and intestinal tract) that may affect either drug bioavailability, or hPTH(1-34) or SNAC metabolism.

• QTcF interval > 470 msec;
• PR > 220 msec;
• QRS > 120 msec.

9. Positive results at screening for human immunodeficiency virus (HIV), hepatitis B surface antigen (HBsAg) or hepatitis C virus (HCV).
