Arm Intervention/treatment
Experimental: 1
Cross-over treatment with increasing doses of PTH134, placebo and active comparator.
Drug: PTH134
Other Name: teriparatid

Primary Outcome Measures :
  1. •Safety and tolerability of ascending single doses of PTH134 over 24 hours as compared to baseline. •Pharmacokinetics after ascending single doses of PTH134, including comparison with reference drug Forteo 20 µg sc over 24 hours.

Secondary Outcome Measures :
  1. •Assessment of PK from PTH134 formulations over 24 hours. •Assessment of the pharmacodynamic profile of serum ionized calcium, total serum calcium, bone biomarkers with reference drug Forteo 20 µg and placebo over 24 hours.
