A Study of Oral Calcitonin Given at Night to Healthy Postmenopausal Women

June 5, 2014 updated by: Tarsa Therapeutics, Inc.

A Randomized, Open-Label, Placebo-Controlled, Two-Period Crossover Study of the Effect on CTx-1 Concentrations of a Single 200 μg Recombinant Salmon Calcitonin (rsCT) Dose Given at Night to Normal, Healthy, Postmenopausal Women

This study is being conducted to assess the plasma CTx-1 concentrations when dosing is at night and to compare these results with those obtained with a placebo control and with commercially available nasal calcitonin.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Timing of the dose of recombinant salmon calcitonin (rsCT) is important in effecting reduction of osteoclast activity. It is theorized that a dose administered before bedtime will be more effective than a dose administered in the morning. See protocol summary for information.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Pharmacodynamic Effect of Oral Calcitonin
Time Frame: 12 hr
C-terminal telopeptide of Collagen Type I (CTx-1) is an established plasma biomarker employed as an index of bone-resorption activity in response to interventions such as an anti-resorptive agent such as calcitonin. Here the calcitonin-salmon is rsCT, (recombinant) both oral and intranasal. These CTx-1 plasma concentrations were collected over 12 hours post-dosing where each subject served as her own control, as all received placebo in this crossover study, to account for the known diurnal variation of plasma CTx-1. For each time point, the ratio of the calcitonin response over the placebo response for that subject was derived from the plasma levels of CTx-1 and reported as a % of the placebo response (% Placebo or %P). These values were used to determine the primary pharmacodynamic parameter of Rmin, the minimum value seen following each active dose. The same %P values were used to derive the secondary pharmacodynamic parameters described in Secondary outc

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Derived Pharmacodynamic Parameters Further Characterizing the Effects of Oral or Intranasal Calcitonin on Plasma CTx-1, Given at Night to Post-menopausal Women
Time Frame: 12 hours
See Primary Outcome description. These CTx-1 plasma concentrations were collected over 12 hours, the values seen following active were compared with the time-matched individual values following placebo and used to derive the pharmacodynamic parameters. The primary was Rmin, seen above, and the Secondary ones were the time to that Rmin (Tmin) and the total time from the beginning of the inhibition to the end of the effect or the end of the study period (Tinhibition).
