NHL Delphi Survey Project: Towards a Core Outcome Set for Non-Hodgkin Lymphoma

The NHL Delphi Survey is currently open. Patients, clinicians, EFPIA members and regulators are invited to participate.

Challenge

At present, several innovative compounds are being tested in clinical trials in order to improve the treatment of Non-Hodgkin Lymphoma (NHL). However, these trials measure different outcomes, thus questioning their comparability. In addition, the majority of clinical trials do not assess long-term side effects and their influence on the patients’ quality of life. A core outcome set (COS) may assist researchers in selecting outcomes for future trials, thereby promoting harmonization of NHL studies and improving clinical management of the disease.

Project Summary

NHL is the most frequent hematologic malignancy in Europe, causing significant morbidity and mortality in both adults and children. To improve the treatment of NHL, several novel treatments are currently being tested in clinical trials. Unfortunately, these trials are insufficiently comparable because they measure different outcomes. In addition, the majority of trials do not assess long-term side effects and their influence on patients’ quality of life. Defining a core outcome set may offer a solution to these problems.

A COS is a minimum set of outcomes to be collected in future clinical trials, which, ideally, have been agreed upon by all stakeholders. The COS is intended as an international standard to evaluate NHL treatments in clinical trials and other research settings (e.g., registry and observational studies). Using a COS will improve the comparability of clinical trials, enhance the consistency of reporting, and reduce selective reporting bias. The COS can also be incorporated into clinical guidelines and be used to improve patient management. This project aims to identify a COS for NHL in adult patients that will be accepted by all of HARMONY’s stakeholder groups.

The researchers will use the Delphi method to develop the COS. First, a preliminary list of about 60 outcomes was created, which is based on literature research and expert interviews. Next, a panel of stakeholders will be asked to rate the importance of each outcome on the basis of their personal experiences. It is planned to have three iterative rounds, using an online survey tool. After each round, the participants will receive an anonymized summary of the survey results per stakeholder group. This will allow them to revise their answers in the next round. It is expected that the group will converge towards a consensus COS after a number of iterations. The process will be stopped after pre-defined consensus criteria have been achieved. The final version of a COS will be aligned in a meeting with all participants.

Panel participants will be recruited from HARMONY Partners, including clinicians, patients, representatives from the pharmaceutical industry, and health authorities. The aim is to recruit equal participant numbers for all stakeholder groups wherever possible. This project is part of a series of Delphi studies for the seven hematological malignancies that are being studied by the HARMONY Alliance. In the future, a COS applicable to all seven hematological malignancies will be defined.
