Study on Daratumumab for Reducing Symptoms in Patients with Moderate to Severe Myalgic Encephalomyelitis/Chronic Fatigue Syndrome

2 1 1

What is this study about?

This clinical trial is focused on studying the effects of a medication called daratumumab on individuals with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS). ME/CFS is a condition characterized by extreme fatigue that doesn’t improve with rest and can worsen with physical or mental activity. The study will compare the effects of daratumumab, which is an anti-CD38 antibody, to a placebo. Daratumumab is administered as a solution for injection.

The purpose of the study is to evaluate how effective daratumumab is in reducing the symptoms of ME/CFS in patients who have moderate to severe forms of the condition. Participants in the study will receive either daratumumab or a placebo through subcutaneous injections, which means the medication is injected under the skin. The study will last for a period of 26 weeks, during which the participants’ symptoms and overall health will be monitored closely.

Throughout the study, the participants’ progress will be assessed using various measures, including their physical function and daily activity levels. The study aims to provide valuable insights into whether daratumumab can help alleviate the symptoms of ME/CFS and improve the quality of life for those affected by this challenging condition.

1 joining the study

Upon joining the study, the patient will be informed about the trial’s purpose, procedures, and potential risks and benefits. The patient will be required to sign an informed consent form, confirming understanding and willingness to participate.

2 initial assessment

The patient will undergo an initial assessment to confirm eligibility. This includes verifying the diagnosis of Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) according to specific criteria, ensuring the patient is between 18 and 64 years old, and confirming the duration of the disease is at least two years.

For women of childbearing potential, a negative serum pregnancy test is required, and effective contraception must be used for a specified period before and after the treatment.

3 baseline measurements

Baseline measurements will be taken to assess the patient’s current health status. This includes recording the DSQ-SF total score, which measures the severity of symptoms, and other health indicators such as physical function and activity levels.

4 treatment administration

The patient will receive the treatment through subcutaneous injection. The medications used are daratumumab and hyaluronidase. The specific dosage and frequency will be determined by the study protocol and communicated to the patient.

The treatment aims to evaluate the efficacy of daratumumab in reducing ME/CFS symptoms compared to a placebo.

5 follow-up assessments

The patient will undergo regular follow-up assessments to monitor the course of the DSQ-SF total score and other health indicators. These assessments will continue until week 60 of the study.

Safety and any potential side effects will be continuously monitored throughout the trial period.

6 completion of the study

Upon completion of the study, the patient will have a final assessment to evaluate the overall response to the treatment. This includes measuring any changes in symptoms and physical function.

The study results will contribute to understanding the effectiveness of daratumumab in treating ME/CFS.

Who Can Join the Study?

Investigated drugs:

Daratumumab is a medication used in this clinical trial. It is an antibody that targets a specific protein called CD38, which is found on the surface of certain cells in the body. In this study, daratumumab is being tested to see if it can help reduce symptoms in patients with Myalgic Encephalomyelitis, also known as Chronic Fatigue Syndrome (ME/CFS). The goal is to see if this medication can improve the condition of people who have moderate to severe symptoms of ME/CFS.

Myalgic Encephalomyelitis/Chronic Fatigue Syndrome – This disease is characterized by extreme fatigue that does not improve with rest and may worsen with physical or mental activity. It often includes symptoms such as muscle pain, memory problems, headaches, and unrefreshing sleep. The condition can lead to a significant reduction in daily activities and quality of life. Symptoms can vary in intensity and may come and go, making it difficult to predict the course of the disease. Over time, individuals may experience periods of improvement followed by relapses. The exact cause of the disease is not well understood, and it can affect people of all ages.
