Trial Outcomes & Findings for 7 Day Continuous Parathyroid Hormone IV Infusion (NCT NCT00377312)

NCT ID: NCT00377312

Last Updated: 2016-03-22

Results Overview

DLT was defined as achieving one major criterion or two minor criteria rated at ≥ 2 on a scale of 0-5. The major criteria were defined as symptomatic orthostatic hypotension (systolic BP fall \>30 mm/hg), tachycardia (pulse \> 120), hypertension (systolic BP \>160 mm/hg on 2 occasions), hypercalcemia (serum calcium ≥ 12 mg/dl), and hypophosphatemia (serum phosphorous \< 1.5 mg/dl). Minor criteria included symptoms such as flushing, nausea, abdominal or muscle cramps, dizziness, lightheadedness, palpitations, etc.

Participant Flow

Starting in October 2006, 19 Healthy caucasian males \& females between 24 - 35 yrs were screened. By November 2007 11 subjects were randomized and 10 completed the one week infusion study which was done on the Clinical and Translational Research Clinic (CTRC) at the University of Pittsburgh Medical Center (UPMC).

Candidates were non-smokers and females had negative pregnancy tests. Those on chronic medications with the exception of oral contraceptives or stable thyroid hormone replacement were excluded. Body mass index had to be less than 30, and all had normal screening labs.
