Population studied

Short description of the study population

All physicians who have received the educational materials in a country where the selfadministration kit for Ruconest has been launched, will be informed on the study by an appropriate Pharming representative.
One year after receipt of the educational materials, the physicians will be asked to participate in an online survey.
All physicians who have prescribed Ruconest (vial-only and/or self-administration kit) to patients with hereditary
angioedema (HAE) at least once during the 12 preceding months will be eligible for participation.

Estimated number of subjects

20
Study design details

Study design

This is a cross-sectional survey among physicians who have received the updatededucational materials for Ruconest for self-administration, prescribe Ruconest, and practice in one of the countries where Ruconest for self administration was formally launched and has been available for one year.

Main study objective

The main objectives of this study are:
• to evaluate the HCPs awareness of the need to take a careful history of rabbit allergy, the need for monitoring for hypersensitivity reactions and knowing what action to take as a measure of the effectiveness of the educational materials.
• to evaluate whether the patient and prescriber checklists, and patient diary have been useful in training patients to enable safe and effective use of Ruconest and that key safety messages are understood by the prescriber and communicated to their patients as a measure of the effectiveness of the educational materials.
A secondary study objective of this study is to evaluate whether the reporting rate of adverse events related to hypersensitivity reactions after administration of Ruconest has changed (based on data from routine pharmacovigilance reporting and PAS study C1 1412).

Setting

The CRO, PAINT-Consult, or directly the Sponsor Pharming Technologies will send an invitation to participate in the survey to the HCPs who received the educational materials.
The survey has been designed to take no more than 30 minutes.
The response rates will be monitored to keep track of the number of completed questionnaires.
Participating HCPs will have the option of receiving compensation for their time and effort.
The amount varies by country and is determined by national laws and reimbursement policies.
Similarly, it will take time for physicians to treat a sufficient number of patients and gain experience in prescribing patients with Ruconest for self-administration and receive feedback from patients.
Therefore, the questionnaire will be distributed one year after launch of the self-administration kit.
Furthermore, the frequency of HAE attacks varies between patients (ranging from one attack per year, up to more than once-weekly attacks) and physicians are known to see the patients generally once or twice a year.
Due to the limited number of EU treatment centres and physicians treating HAE patients, the duration and extent of this study is intended to encompass a minimum of 20 completed questionnaires from at least 4 different countries.
The distribution and collection of the questionnaires will continue for at least one year after first start of data collection.

Comparators

None

Outcomes

The outcome of the survey is the proportion of physicians that correctly respond to individual items of the questionnaire.
The proportion responding correctly will be tabulated separately for each item.
Physician’s demographic information will be collected in order to further characterise the respondent population.
This will include country, type of medical practice, and (range of) number of HAE patients treated.

Data analysis plan

Data analysis will be descriptive. Awareness, knowledge, and adherence will be evaluated and results will be expressed as percentages and means by question and HCP, as applicable. No formal hypothesis testing will be conducted.
The following items will be reported, as appropriate:
- number of HCPs receiving the (updated) educational materials pack
- number of questionnaires sent out to HCPs
- number and percentage of HCPs eligible and ineligible for participation
- number and percentage of HCPs who completed the questionnaire
- frequency distribution of responses to each question
The outcomes will be summarised for all countries combined, and per country if possible. Additional analyses may be performed as needed.
Physicians’ general medical practice and demographic data are intended to explore possible differences between physician’s subsets in understanding, knowledge and use of the educational materials.
