  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Diagnosis of bilateral, idiopathic Parkinson's Disease (PD) based on UK Brain Bank criteria with motor complications despite adequate oral antiparkinsonian therapy.
  • At least 5 years disease duration, relative to the anticipated date of surgery, since diagnosis of PD.
  • Males or nonpregnant females 35-75 years of age, inclusive.

  • Stable doses of antiparkinsonian medications and parkinsonian features for the 60-day period preceding the surgical procedure.
  • No conditions that would render the subject unsuitable for surgery, or that would interfere with any of the assessments of efficacy or safety in this trial.
  • Subject's informed consent prior to the performance of any study-specific procedures.

Who cannot join

  • Subjects with atypical or secondary parkinsonism.
  • Any subject, in the judgment of the investigator, for whom participation in the study would pose a safety risk including, but not limited to, a history of any clinically significant medical, psychiatric, or laboratory abnormality.
  • History of treatment of PD by any procedure involving intracranial surgery or implantation of a device.
  • MRI of the brain within 12 months before the surgical procedure that indicates the presence of an abnormality that may interfere with the assessments of safety or efficacy or would, in the judgment of the investigator, represent a surgical risk to the subject.
  • Any disorder that precludes a surgical procedure (e.g., signs of sepsis or inadequately treated infection) or alters wound healing.
  • Receipt of antiplatelet agents for at least 10 days prior to the surgical procedure.
Show all 14Show fewer
  • A score of less than or equal to 27 on the Folstein Mini-Mental examination performed during the eligibility evaluation period or clinical evidence of cognitive impairment that would affect the subject's ability to sign the informed consent or perform any of the protocol required assessments.
  • Chemotherapy, cytotoxic therapy, or immunotherapy within 6 weeks prior to the surgical procedure.
  • Vaccinations within 30 days prior to the surgical procedure.
  • History, within 2 years before the surgical procedure, of drug or alcohol abuse.
  • Treatment with neuroleptics within 1 year before the surgical procedure.
  • Any medical disability (e.g., severe degenerative arthritis, compromised nutritional state, peripheral neuropathy) that would interfere with the assessment of efficacy and safety in this trial or would compromise the ability of the subject to undergo study procedures (e.g., MRI, PET), or give informed consent.
  • History of prior gene transfer therapy.

About this study

Official title: Multicenter, Randomized, Double-Blind, Sham Surgery-Controlled Study of CERE-120 (Adeno-Associated Virus Serotype 2 [AAV2]-Neurturin [NTN]) to Assess the Efficacy and Safety of Bilateral Intraputaminal (IPu) Delivery in Subjects With Idiopathic Parkinson's Disease

The purpose of this double blind study is to determine whether CERE-120 (adeno-associated virus serotype 2 [AAV2]-neurturin [NTN]) is effective and safe in the treatment of patients with idiopathic Parkinson's Disease. CERE-120 is administered via bilateral stereotactic injections targeting the putaminal region of the brain. The design of this study involves approximately 34 patients receiving CERE-120 treatment via stereotactic surgery and approximately 17 patients receiving sham stereotactic surgery (no CERE-120 administered).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. UPDRS Part III OFF

    The UPDRS (Unified Parkinson's Disease Rating Scale) is a clinical rating scale that assesses the symptomatic burden of Parkinson's Disease. The scale has four main sections, and each item is scored from a 0 to a 4 (higher number is more severe manifestation). Part III is a subsection devoted to motor function, has 14 questions, resulting in a score range of 0 (unaffected) to 56 (severely affected). The scale is administered by a trained clinician, and patients were assessed in a practically defined "off" condition, 12 hours or more after the last administration of medication.

    Measured: Change from Baseline to 12 Month Visit

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing CERE-120 (Adeno-Associated Virus Serotype 2 [AAV2]-Neurturin [NTN]) in people with Idiopathic Parkinson's Disease, run by Sangamo Therapeutics at 9 sites 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 7 inclusion and 14 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: finished, as of the sponsor's last update on 10 Nov 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 9 sites 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. Some participants in this study may receive a placebo. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 14 Aug 2012). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

UPDRS Part III OFF (time frame: Change from Baseline to 12 Month Visit). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00400634, which also lists 1 linked publication.

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 10 Nov 2022.
