About this study

Official title: The Challenge of Treating Orphan Diseases With Novel Therapies: Experience From One Adult Metabolic Clinic in Switzerland

The aim of this study is to report and describe all the patients with confirmed diagnosis of inherited metabolic disease (IMD) treated with orphan medicinal products (OMPs) in a cohort of adult patients followed in a reference center for rare diseases (Lausanne University Hospital, CHUV) from 2017-2022.

Read the detailed description

The development of novel therapies for inherited metabolic diseases, considered has OMPs, has improved the care of these patients. OMPs include a wide range of therapies from dietary products, enzyme replacement, substrate inhibitors, coenzyme replacement to more recently, gene therapy. Despite an increasing use of these therapies, they are still considered highly specialized treatments for very small groups of patients and share the characteristic of aiming to treat small populations with targeted therapies, which leads to higher costs and difficulties in obtaining clinical evidence. Drugs are approved for marketing and orphan designation by medical agencies based on their efficacy and safety.

In Switzerland, a separate country-specific process decides whether an approved drug is reimbursed. Because of the growing number of expensive OMPs, their reimbursement through public health insurances is increasingly manifesting itself as a moral dilemma for decision-makers. It may take a median of several years after submission of the first application by a pharmaceutical company for an orphan drug to become available to patients.

Considering the increasing number of OMP approvals and the still ethical challenge concerning their reimbursement, this study aims to share the experience of a single center in treating adult IMDs with OMPs but also in implementing novel therapies for rare diseases not yet covered by health insurers in Switzerland.

A database was created in 2017 including all patients with IMD followed at the Adult Metabolic Clinic in the CHUV. This database was part of a protocol submitted and approved by the Ethics committee (# 2017-02328). The results of this first analysis were published in the Journal of Orphan Rare Diseases. Investigators will use this database to identify all the patients treated with OMPs. Electronic and paper patient charts from the Division of Genetic Medicine will be reviewed for type of IMD and treatment. All variables will be entered in an excel database.

Questions about this trial

What is this clinical trial studying?

An observational study of Inborn Errors of Metabolism, run by University of Lausanne at 1 site in Switzerland.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 4 Dec 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Switzerland. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Specific diagnosis of Inherited Metabolic Diseases listed by their frequency (time frame: Day1). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05818566, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Dec 2024.
