Study summary

The purpose of the study is to evaluate the effectiveness of the Medtronic Adaptive DBS therapy (aDBS) for Parkinson's Disease in China with the Percept family of Implantable Neurostimulators (Percept PC and Percept RC).

Read the detailed description

The ADAPT-PD China Study will utilize both Dual and Single Threshold aDBS modes (algorithms). Prospective, multicenter, open label comparison (with single-blind aDBS mode from aDBS randomization to evaluation phase), single arm clinical trial designed to evaluate the effectiveness of the Medtronic Adaptive DBS therapy (aDBS) for Parkinson's Disease in China with the Percept family of Implantable Neurostimulators (Percept PC and Percept RC).

The study is expected to be conducted at approximately 5 centers located in China.

Inclusion criteria

General (Assessed at Enrollment Visit):

  1. Subject has idiopathic Parkinson's disease

Subject is implanted (>3 months prior to enrollment for new INS implants or >1 month from INS replacement) with a Percept PC (Model B35200) or Percept RC (Model B35300) and Medtronic DBS leads (Model 3387, 3389, B33005 or B33015) and extensions (Model 37086 or B34000) bilaterally in the same target (physician confirmed), STN or GPi
  3. In the opinion of the investigator, the subject responds to DBS Therapy.
  4. Based on the opinion of the investigator, the subject's cDBS parameters and PD medications are stable (no changes within the last 4 weeks) and expected to remain stable from enrollment through the end of the aDBS Evaluation Phase
  5. Subject is configured to monopolar or dual monopolar stimulation using contacts 1 and/or 2 (9 and/or 10) on at least one side
  6. Subject is willing and able to attend all study-required visits and complete the study procedures (e.g. 1-month recall questionnaires, MDS-UPDRS III, Off stim/Off med visit)
  7. Subject (or legally authorized representative) has the ability to understand and provide written for participation in the study prior to the study-related procedures being conducted

LFP Screening Inclusion Criteria (Conducted during LFP Screening Visit):

1. Subject has Alpha - Beta band (8-30 Hz) amplitude ≥ 1.2 μVp detected on either left and/or right DBS leads on sensing channels 0-2, 0-3, 1-3, 8-10, 8-11, or 9-11.

Exclusion criteria

Exclusion Criteria:

General (Assessed at the Enrollment Visit):

  1. Subject and/or caregiver is unable to utilize the patient programmer
  2. Subject has more than one lead in each hemisphere of the brain
  3. Subject has cortical leads or additional unapproved hardware implanted in the brain
  4. Subject has more than one INS
  5. At enrollment, the subject's INS has a predicted battery life of \<1 year
  6. Subject has Beck Depression Inventory II (BDI-II)>25
  7. Subject requires diathermy, transcranial magnetic stimulation (TMS), or electroconvulsive therapy (ECT)
  8. Subject has a metallic implant in the head, (e.g., aneurysm clip, cochlear implant)
  9. Subject has, or plans to obtain, an implanted electrical stimulation medical device anywhere in the body (e.g., cardiac pacemaker, defibrillator, spinal cord stimulator)
  10. Subject has, or plans to obtain, an implanted medication pump for the treatment of Parkinson's disease (e.g., DUOPATM infusion pump) and/or portable infusion pump
  11. Based on the opinion of the investigator, the subject has an abnormal neurological examination that would preclude them from study participation
  12. Subject is breast feeding
  13. Subject is under the age of 18 years
  14. Subject is currently enrolled in or plans to enroll in any concurrent drug and/or device study that may confound the results of this study as determined by the Medtronic study team
  15. Subjects with signal artifact on all 6 aDBS sense pathways (3 each on both DBS leads) which preclude the clinician from setting thresholds
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Interventions

  • DevicePercept™ PC and Percept RC with Adaptive DBS (aDBS™)

    Subjects for whom meet the LFP screening criteria and can be acceptably configured on the "Best" aDBS mode (Dual or Single Threshold) will receive "Best" Mode aDBS treatment and enter the aDBS Evaluation Phase.

What researchers measure

Primary outcomes

  1. "On" time without troublesome dyskinesia (i.e. Good "On" Time)

    Proportion of aDBS subjects meet a success criterion relative to stable cDBS.The success criterion: no worse than 2 hours/day less of "On" time without troublesome dyskinesia (i.e. Good "On" Time) during aDBS compared to cDBS.

    Time frame: From the cDBS baseline to aDBS evaulation phase at about 1 month

Other outcomes

  1. Assess the Adverse Event among the Participants

    To characterize: * Stimulation-related adverse events (AEs) * Adverse events including serious adverse events (SAEs) and device deficiencies

    Time frame: From enrollment to the end of treatment at around 12 months to 17.5 months

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Nov 2025 (actual). Primary completion is estimated for Jan 2027, 14 months after the start.

Of 76 industry-sponsored interventional studies with no phase under Parkinson Disease, half reached primary completion within 27 months of starting (the median), counting those still running; a quarter within 17 and three quarters within 43. This study's planned 14 months is below that.

Counting every sponsor, half of 1,367 studies reached it within 25 months; a quarter within 11 and three quarters within 44.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 10, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
