About coreHEM-MHO

Developed through an initiative co-led by NBDF, coreHEM Mental Health Outlook questionnaire (coreHEM-MHO) is a patient-reported outcome measurement (PROM) instrument that assesses mental health outlook (including psychological status and emotional functioning) associated with receiving gene therapy or any durable treatment for hemophilia.

The coreHEM-MHO instrument is owned by NBDF and available for use in research and within clinical trial settings through a license agreement. Certified translations are available for multiple countries and languages. coreHEM-MHO has been content validated for use in men and adolescents 15 years or older who have hemophilia.  It is recommended that coreHEM-MHO be used at baseline and at periodic timepoints after dosing.

coreHEM-MHO consists of 26 questions in two parts. The first 20 questions are suitable regardless of treatment therapy. The additional 6 questions are specific for those considering or who have been treated with gene therapy.

History

In 2017, the National Bleeding Disorders Foundation, the Center for Medical Technology Policy and McMaster University partnered to develop a core outcome set (COS) for gene therapy in hemophilia. The aim of the coreHEM project was to determine the set of outcome measures required to evaluate efficacy, safety, comparative effectiveness, and value of gene therapy for hemophilia.

The coreHEM project was a multi-stakeholder initiative that prioritized a list of outcomes that are recommended for use in all clinical trials for gene therapy for hemophilia. coreHEM utilized a modified Delphi consensus process, based on methods adapted from the Core Outcome Measures in Effectiveness Trials (COMET) Initiative and involved forty- nine participants (five patients, five clinicians, five researchers, four regulators, three research agencies, six health technology assessors, nine payers, and twelve drug developers). The involvement of lived experience experts (LEEs, aka patients) ensured that selected outcomes were meaningful and relevant to persons living with hemophilia. In addition to regulatory-mandated adverse effects, six outcomes were identified as the COS and include: bleed frequency, factor activity level, duration of expression, chronic pain, healthcare resource use, and mental health outlook.

While the unique impact of gene therapy on the mental health outlook of persons with hemophilia was recognized as an important outcome, at that time, there were no patient-reported outcome measurement (PROM) instruments to sufficiently measure it. Subsequently, the coreHEM Mental Health Outlook Initiative was created and tasked with developing such tool. coreHEM-MHO is a content validated PROM instrument used to assess the mental health outlook associated with receiving gene therapy or any durable treatment for hemophilia.

 

Using coreHEM-MHO

coreHEM-MHO is used to assess the mental health outlook associated with receiving gene therapy or any durable treatment for hemophilia in men 15 years and older. coreHEM defines Mental Health Outcome as “A person’s psychological status; whether a person has positive feelings (joy, excitement, ease of living, new outlook on life) or negative feelings (anxiety, depression, fear, and uncertainty) associated with having hemophilia, or the treatment of hemophilia.”

coreHEM-MHO is a content-validated patient-reported outcome measure (PROM) instrument appropriate for use as an exploratory endpoint in clinical trials, for research in the clinical setting, and longitudinally in registries and long-term follow-up studies. It can be used to support value assessment and to inform market access and other post-regulatory decisions.

coreHEM MHO asks questions about mental health aligned within five domains: stigma, anxiety, depression, life interference, and identity. There are two sections: the first section can be used for people on any treatment for hemophilia and contains 20 questions about the mental health impact of living with and treating hemophilia. The second section is gene-therapy specific. This section contains 6 questions and should be included in studies where participants have had or are going to receive gene therapy. The two sections are scored separately. Both sections are scored from 0 to 1, where a score closer to 1 indicates a better mental health outlook.

When used in a study or trial, it is recommended that coreHEM MHO is administered at baseline (before gene therapy infusion or before a treatment change), and then again, every three months for the first year. After the one-year follow-up, it is recommended to be taken yearly. Scores from different time points can be compared to demonstrate changes in mental health outlook.

coreHEM-MH is owned by NBDF and available for use through a license agreement. It has been translated into 20 languages.
