Trial Outcomes & Findings for Measurement of Relaxin Peptide in Multiple Sclerosis (MS) (NCT NCT01909492)

NCT ID: NCT01909492

Last Updated: 2025-06-22

Results Overview

There is no information available on what serum and CSF levels of RLX are observed in patients with active versus stable relapsing MS, how these values compare to that found in human volunteers without MS or other inflammatory diseases, and whether RLX functions normally in subjects with active or stable MS. RLX2 concentrations were expressed as picomoles per milliliter (pmol/mL) of serum or CSF.

Group 1
Group 1 will consist of 10 subjects with suspected MS, who have had a clinical attack within the last 12 weeks, have at least one gadolinium-enhancing lesion on brain or spinal cord MRI taken within the prior 4 weeks, and for which they have not received any immunomodulating or immunosuppressant medication. Patients will have a blood draw to provide serum and a CSF will be obtained through a lumbar puncture. Blood Draw: Patients will provide a serum sample for research. Lumbar Puncture: Patients will have a lumbar puncture to obtain CSF.
Group 2
Group 2 will consist of 10 subjects with clinically stable definite MS, with no evidence of clinical relapse for at least the past 12 weeks, and have no gadolinium enhancing lesions on MRI in the prior 4 weeks. These subjects will fulfill the Revised (2010) McDonald's Criteria for the Diagnosis of MS. Patients will have a blood draw to provide serum and a CSF will be obtained through a lumbar puncture. Blood Draw: Patients will provide a serum sample for research. Lumbar Puncture: Patients will have a lumbar puncture to obtain CSF.
Group 3
Group 3 will consist of 10 subjects without evidence of inflammatory systemic or inflammatory central nervous system disease, who require CSF removal for some other cause, such treatment of benign intracranial hypertension or as part of the procedure for insertion of an intrathecal medication delivery system. Patients will have a blood draw to provide serum and a CSF will be obtained through a lumbar puncture. Blood Draw: Patients will provide a serum sample for research. Lumbar Puncture: Patients will have a lumbar puncture to obtain CSF.
