About this study

Official title: Senolytics to Improve Physical and Cognitive Function in Older Adults With Multiple Sclerosis

This is a clinical trial to see whether senolytic therapy is safe and feasible for patients with secondary progressive MS and whether treatment improves physical and thinking abilities. The study seeks to enroll adults with secondary progressive MS (SPMS), aged 50-85, who are not currently taking a MS disease-modifying therapy and have noticed their MS symptoms getting worse. People who join the study will take the medicines dasatinib and quercetin by mouth every two weeks for three months. These medicines work together to remove old, damaged cells that may cause inflammation and slow the repair of nerves. Participants will also be followed for one year from enrollment to monitor for treatment effects.

Read the detailed description

Multiple sclerosis (MS) is a chronic immune-mediated inflammatory and neurodegenerative disorder of the central nervous system (CNS), which afflicts approximately one million people in the United States. Age is the strongest driver of disease course in MS. With increasing age, most older adults with MS develop a progressive disease phenotype characterized by gradual accrual of irreversible neurological disability, for which there are no effective treatments that reliably slow disease progression. Cellular senescence is a hallmark of aging, whereby senescent cells accumulate with age and produce mediators of inflammation through the senescence-associated secretory phenotype (SASP). In MS, senescent cells have been identified in both the central nervous system and peripheral immune compartments contributing to SASP expression, promoting chronic inflammation, axonal damage, and failure of myelin repair, and ultimately leading to functional decline. Senescent cells can be selectively removed by senolytic drugs, which delay age-related dysfunction in animal models and show potential for improving functional outcomes in human clinical trials. The senolytic drug combination of dasatinib and quercetin (D+Q) selectively induces apoptosis of senescent cells in human tissue. Our pilot data shows D+Q treatment improves function and survival in experimental autoimmune encephalomyelitis, the widely used animal model of MS. Emerging evidence from early phase clinical trials of D+Q in age-related diseases shows improvement of gait speed in idiopathic pulmonary fibrosis and CNS penetrance of dasatinib in Alzheimer's disease. However, studies of senolytic therapy for people with MS have yet to be conducted. The investigators hypothesize that treatment with D+Q will be well tolerated, improve physical and cognitive function, reduce circulating biomarkers of senescence and neurodegeneration, and attenuate T-cell immune exhaustion. The investigators will test this hypothesis through a single arm, open label, study to 1) determine the feasibility of 3 months of intermittent D+Q treatment in 30 older adults age 50-85 with secondary progressive MS and 2) to obtain preliminary data of D+Q treatment on physical and cognitive function and 3) serum biomarkers of senescence, neurodegeneration, and the circulatory T cell repertoire. Targeting cellular senescence represents a novel strategy for treating progressive MS, and results from the study will lay the foundation for a future randomized controlled trial of senolytics to treat progressive MS.

Individual data sharing
Undecided: The data management and sharing plan will be consistent with the NIH Data Sharing Policy and Implementation Guidance which recognizes the need to make the research data generated from the NIH support projects available to the scientific community while ensuring that the privacy and autonomy of research participants are respected, and that confidential/proprietary data are appropriately protected. Data will include demographic, clinical, functional, and cognitive data from study participants, in addition to banked blood, urine, and lymphocytes. All investigators wishing to access the data will submit a brief proposal to Drs. Zhang or Kirkland describing their research project, data needs, regulatory approvals, and mechanisms to assure patient confidentiality. Upon affirmative review by the Dr. Zhang and co-investigators of this study, a data-sharing agreement will be signed and the requesting investigators will be given a working electronic data file and appropriate documentation.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Dasatinib and quercetin in people with Multiple Sclerosis (MS) Secondary Progressive, run by Ohio State University at 1 site in United States.

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 3 inclusion and 22 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: opening soon, as of the sponsor's last update on 8 Dec 2025. 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 United States. 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.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

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

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Participant retention rate (time frame: Baseline until 3 months). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 8 Dec 2025.
