Study of Patients With ITP Estimating the Proportion Administering Romiplostim Correctly After Receiving Home Administration Training

December 21, 2015 updated by: Amgen

A Cross-sectional Study of Patients With Immune Thrombocytopenic Purpura and Caregivers to Estimate the Proportion Who Administer Romiplostim Correctly After Receipt of Home Administration Training Materials

Cross-sectional study, observation made by healthcare professionals of subjects or caregivers, administering romiplostim at their first standard-of-care visit 4 weeks after training with the home administration training pack. Further observations can also be recorded in the study if made within 16 weeks of enrolment. Data will be collected from the subjects' dose diary at their first standard of care visit to ensure there were no problems with administration while not at the clinic.

Study Overview

Status

Indicates the current recruitment status or the expanded access status.

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.

Detailed Description

This cross-sectional study involves direct observation by a healthcare professional of a series of subjects and caregivers in the act of administering romiplostim at their first standard-of-care visit occurring 4 weeks after training with the HAT pack. Further observations, if they occur, will also be recorded in the study if made within 16 weeks of enrolment. (Additional observations are voluntary and are not required for study participation; they occur only if the healthcare professional requests them.) Additionally, data will be collected from the subjects' dose diary at the first standard of care visit to ensure there were no problems with administration while not at the clinic.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 100 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

ITP patients being treated with romiplostim will be approached for possible study participation. At each participating site, patients that meet the following criteria will be enrolled as a study subject. Adult ITP patients, treated per EU Summary of product characteristics (SmPC), or caregiver new (or at least a 3 month gap) to administering romiplostim, that has received HAT pack training and is available at a standard-of-care medical visit 4 weeks (range 2 to 8 weeks) after HAT pack training, the patient provides informed consent.

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
Successful self administration of romiplostim
Time Frame: First Standard of Care visit post Home Administration Training (range 2-8 weeks)
to estimate the proportion of subjects and caregivers who administer romiplostim correctly after being trained with the HAT pack.
First Standard of Care visit post Home Administration Training (range 2-8 weeks)

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
successful reconstitution of romiplostim
Time Frame: First standard of care visit post Home Administration Training (range 2-8 weeks). Follow up visits (up to 16 weeks post enrolment)

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date.
