Clinical Trials Guide for Corticobasal Degeneration and Progressive Supranuclear Palsy

Overview

This guide provides comprehensive information for patients, caregivers, and clinicians seeking to participate in or learn about clinical trials for corticobasal degeneration (CBD) and progressive supranuclear palsy (PSP). These rare neurodegenerative disorders have limited treatment options, making clinical trial participation crucial for advancing therapeutic development.[@litvan2017][@armstrong2013][@hoglinger2021][@stamelou2022]

Clinical trials offer access to experimental treatments while contributing to scientific understanding of these conditions.[@clinicaltrialsgov][@curepsp] This guide covers trial search strategies, active trials, enrollment considerations, and resources for connecting with research programs.[@stamelou2022][@ghebremichael2022]

Pathway Diagram

Mermaid diagram (expand to render)

Understanding Clinical Trial Phases

Clinical trials proceed through distinct phases, each serving specific purposes in evaluating safety and efficacy.[@clinicaltrialsgov]

Phase 1 trials focus on safety, enrolling a small number of participants (typically 20-80) to evaluate side effects and determine appropriate dosing. These trials primarily assess tolerability and pharmacokinetics.[@clinicaltrialsgov]

Phase 2 trials expand enrollment (typically 100-300 participants) to further evaluate efficacy and continue safety assessment. These trials often use placebo controls and may include dose-response studies.[@clinicaltrialsgov]

Phase 3 trials confirm effectiveness, monitor side effects, and compare the experimental treatment to standard care. These larger trials (typically 1,000-3,000 participants) provide the primary evidence for regulatory approval.[@clinicaltrialsgov]

Phase 4 trials occur after FDA approval and monitor long-term safety in broader populations.[@clinicaltrialsgov]

ClinicalTrials.gov Search Strategy

Effective Search Techniques

[ClinicalTrials.gov](https://clinicaltrials.gov) serves as the primary registry for clinical trials worldwide. Effective search strategies for CBD and PSP include:[@clinicaltrialsgov]

Condition-based searches: Use "Progressive Supranuclear Palsy" or "Corticobasal Degeneration" as primary search terms

Expanded searches: Try "Parkinson Plus Syndrome," "Atypical Parkinsonism," or "Tauopathy" to capture related trials

Intervention searches: Search by mechanism (e.g., "tau aggregation inhibitor," "microglia modulation") or drug names

Location filtering: Use geographic filters to find trials within reasonable travel distance

Active PSP Trials

Currently Recruiting Trials

Trial Details

NCT05297202 - Lithium for PSP — Phase 2 Trial
This Phase 2 trial evaluates low-dose lithium as a disease-modifying treatment for PSP. Lithium inhibits glycogen synthase kinase-3 beta (GSK-3β), a kinase that hyperphosphorylates tau protein, promoting its aggregation into neurofibrillary tangles. The trial targets serum lithium levels of 0.6-0.8 mEq/L to achieve CNS penetration while minimizing mood-related side effects. Primary endpoint is change in PSP Rating Scale (PSPRS) at 12 months. See [Lithium for PSP — Phase 2 Trial](/clinical-trials/lithium-psp-phase-2-nct05297202) for detailed mechanism and eligibility.

NCT02994719 - Gait Analysis in Neurological Disease

This observational study systematically assesses laryngeal and pharyngeal function in patients with neurodegenerative diseases including PSP. Using fiberoptic endoscopic evaluation of swallowing (FEES), researchers aim to characterize dysphagia patterns and develop better management strategies. This is particularly relevant for PSP patients who often develop life-threatening swallowing difficulties.[@ncti]

NCT03638505 - Quality of Life and Caregiver Burden in PSP
This French observational study focuses on quality of life for PSP patients and the burden on caregivers. Given the significant impact of PSP on both patients and families, understanding these factors is crucial for developing comprehensive care approaches. The study may inform support strategies and intervention planning.[@nctj]

NCT07136844 - Gait and Upper Limb Evaluation (ActiLiège-Adult)
This Belgian observational study collects natural history data on gait parameters and upper limb function in patients with neurological diseases. While targeting multiple conditions, the standardized assessment protocols may yield insights applicable to PSP and CBS patients. The study uses quantitative movement analysis to track disease progression.[@nctk]

NCT03872102 - Neuroimaging for Parkinsonian Syndromes
This French study aims to identify neuroimaging biomarkers that can differentiate Parkinson's disease from atypical parkinsonism (including PSP and CBS) and predict progression rates. Using advanced MRI techniques, researchers seek to improve diagnostic accuracy and prognostic capabilities—critical needs given the clinical overlap between these conditions.[@nctl]

NCT07392411 - AI-Based Facial/Speech Patterns
This Chinese study employs artificial intelligence to analyze facial expressions and speech patterns in Parkinson's disease and related disorders. Digital biomarkers derived from these analyses may aid in early diagnosis and disease differentiation. The approach could potentially be applied to CBS and PSP as well.[@nctm]

NCT02605785 - Molecular Anatomic Imaging of Tau in PSP
This Phase 2 study uses PET imaging to visualize tau protein distribution in the brains of PSP patients. Understanding tau burden and its correlation with clinical symptoms may help guide therapeutic development and patient stratification for clinical trials.[@nctn]

This trial targets cellular energy metabolism, which is impaired in these rapidly progressive neurodegenerative disorders. Patients with PSP, MSA, or CBS may be eligible.

NCT07291687 - tDCS for Motor Function
This device study evaluates transcranial direct current stimulation (tDCS) as a treatment for motor function in neurodegenerative diseases. tDCS is a non-invasive brain stimulation technique that may improve motor symptoms by modulating cortical excitability. The study combines tDCS with motor training.

NCT05653778 - Scrambler Therapy for CBS Pain
This pilot trial tests whether scrambler therapy is an effective treatment for neuropathic pain in patients with corticobasal syndrome. Scrambler therapy is a non-invasive neuromodulation technique that uses electrical signals to replace pain with non-painful sensations. This addresses a significant quality-of-life issue in CBS patients.

CBS/PSP Overlap Trials (Relevant to Both Conditions)

Many clinical trials enroll patients with either CBS or PSP since both are 4R tauopathies with similar pathological mechanisms:

Trial Enrollment Guidance

Eligibility Considerations

Trial eligibility depends on specific criteria designed to ensure participant safety and scientific validity:

Diagnostic criteria: Most trials require confirmed diagnosis by specific clinical criteria (e.g., NINDS PSP criteria or MDS criteria for PSP; Armstrong criteria for CBD).[@litvan2017][@armstrong2013][@roemer2018][@coughlin2022][@stamelou2020]

Disease stage: Trials typically enroll patients at specific disease stages. Early-stage patients may qualify for disease-modifying trials, while later-stage patients may be eligible for symptomatic treatment studies.[@hoglinger2021][@stamelou2022][@williams2005]

Age requirements: Most trials require participants be between 40-85 years old, though criteria vary by study.[@ghebremichael2022]

Exclusion criteria: Common exclusions include significant medical comorbidities, prior deep brain stimulation, participation in other trials within specified timeframes, and contraindicated medications.[@hoglinger2021][@ghebremichael2022]

Tau aggregation inhibitors: Drugs designed to prevent tau protein misfolding and aggregation. The TauRx LMTM program has evaluated this approach in PSP.

Anti-tau antibodies: Monoclonal antibodies targeting extracellular tau to prevent propagation. Several companies have developed anti-tau antibodies in clinical trials.[@boxer2020][@vandevrede2020][@wen2021]

Tau phosphorylation modulators: Drugs targeting kinases (e.g., GSK-3β, CDK5) or promoting phosphatases to reduce tau phosphorylation.[@hoglinger2021][@stamelou2022][@bjornsdottir2018][@williams2005]

Neuroprotective Strategies

Cell-based therapies: Stem cell approaches aim to replace damaged neurons or provide neurotrophic support.[@pascual2021]

Mitochondrial protectors: Drugs targeting mitochondrial dysfunction, a key feature of PSP pathology.[@hoglinger2021][@jabbari2020][@holmes2019][@roemer2018]

Anti-inflammatory agents: Microglia-modulating approaches aim to reduce neuroinflammation.[@holmes2019]

Biomarker-enriched enrollment and subtype stratification are increasingly used in modern PSP/CBS trials: tau PET and CSF signatures can improve cohort homogeneity, while neurofilament light chain and genotype-aware analyses (including MAPT haplotype context) may improve power in small populations.[@wen2021][@jabbari2020][@sanchez2019][@bjornsdottir2018][@schott2021][@stamelou2020]

Non-Pharmacological and Device-Based Therapies

Several device-based and non-pharmacological approaches are being investigated for CBS and PSP:

Transcranial Direct Current Stimulation (tDCS): Non-invasive brain stimulation that modulates cortical excitability. Current trials (NCT07291687) evaluate tDCS combined with motor training to improve motor function in neurodegenerative diseases.[@nctf]

Transcranial Magnetic Stimulation (TMS): Another non-invasive technique being studied in PSP (NCT04468932) for potential benefits on motor and cognitive symptoms.[@ncth]

Scrambler Therapy: A novel neuromodulation technique for chronic neuropathic pain. Being evaluated in CBS patients (NCT05653778) where pain is a significant symptom affecting quality of life.[@nctg]

Deep Brain Stimulation (DBS): While not currently in active trials for CBS/PSP, DBS has been explored for symptom management in related disorders.

Metabolic and Energy-Based Approaches

NAD+ Replenishment Therapy: The NADAPT trial (NCT06162013) targets cellular energy metabolism, which is impaired in PSP, MSA, and CBS. This novel approach aims to improve mitochondrial function through NAD+ precursor supplementation.[@ncte]

Failed and Terminated Trials

Documenting failed trials is critical for understanding what approaches have been tried and why they did not work. Several PSP clinical trials have been terminated or completed without success:

UCB0107 Long-term Safety Study (NCT04658199): This study evaluated the long-term safety and tolerability of UCB0107, a tau-targeted antibody, in PSP patients who had previously participated in earlier-phase studies. While the extension study assessed safety, the original efficacy trials did not meet their primary endpoints.

Gosuranemab (BIIB092): This anti-tau antibody targeting extracellular tau oligomers was evaluated in PSP. The trial was terminated based on futility analysis — the antibody did not demonstrate sufficient efficacy to warrant continuation.

Tilavonemab (ABBV-8E12): Another anti-tau antibody targeting tau aggregates. The PSP trial was terminated after interim analysis suggested lack of efficacy.

NNIPPS Study (NCT00211224): Neuroprotection and Natural History in Parkinson's Plus Syndromes — this study was terminated. It had aimed to evaluate neuroprotective strategies in PSP and related disorders.

Understanding why these trials failed provides important mechanistic insights:

Tau antibodies: Targeting extracellular tau may not be sufficient if intracellular tau propagation is the primary driver of pathology
Single-target approaches: PSP is a complex multifactorial disease; single-target interventions may need combination approaches
Biomarker selection: Patient stratification using appropriate biomarkers may be critical for demonstrating efficacy
