An Observational Study of Patients With Moderate Parkinson's Disease (TRANSCEND 1)

December 17, 2025 updated by: Novo Nordisk A/S
The main purpose of this study is to follow and observe a group of people living with Parkinson's disease to see how study participation affects their signs and symptoms in the months after starting in the study. While taking part in this study participants will take their usual medication as prescribed. However, the study doctor may recommend adjustments to their medication to provide a better treatment of their Parkinson's disease. Participation will last from 3 up to 24 months. During visits to the clinic, the study doctor or study nurse will evaluate signs and symptoms of Parkinson's disease using several different assessments. At a minimum of 2 visits participants will be asked to undergo 'off'-assessments.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

50 years to 68 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Participants with Parkinson's disease will be included. The participants will not receive any investigational treatment in this study.

Description

Inclusion Criteria:

  • Male or female, aged 50-68 years (both inclusive) at the time of signing informed consent.
  • Diagnosed with Parkinson's disease using the Movement Disorder Society (MDS) criteria (fulfilling the definition of clinically probable Parkinson's disease).
  • Moderate Parkinson's disease, e.g. as defined by i) modified Hoehn and Yahr stage 2-3 in OFF state and ii) MDS-Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Part III total score greater than or equal to (≥) 30 in OFF state, both as judged by the investigator.
  • Patient has symptoms that are not adequately controlled by existing oral anti-Parkinson's disease medications, i.e., having both ON and OFF periods, as judged by the investigator.
  • Parkinson's disease duration greater than (>) 5 years and lesser than or equal to (≤) 12 years from diagnosis at the time of signing informed consent.
  • Potential candidate for a future cell therapy transplantation, as judged by the investigator.
  • Life expectancy >7 years as judged by the investigator.

Exclusion Criteria:

  • Any atypical or secondary Parkinson's disease, or non-Parkinson's disease-suspected cause(s) of, or contributors to, parkinsonism, as judged by the investigator.
  • Significant drug-induced dyskinesias as judged by the investigator, e.g., as defined by a score of > 2 in the Abnormal Involuntary Movement Scale (AIMS), in any body part in the ON state.
  • Tremor-dominant Parkinson's disease, as judged by the investigator.
  • Cognitive impairment predictive of dementia (including Parkinson's disease dementia) or other cognitive dysfunction as judged by the investigator, e.g., as defined by Montreal Cognitive Assessment (MoCA) score ≤ 24, or evidence of major neurocognitive disorder according to the Diagnostic and Statistical Manual of Mental Disorders V (DSM-V) criteria.
  • Major medical or psychiatric disorder (e.g., depression (Montgomery-Asberg Depression Rating Scale (MADRS) >20) or psychosis), or other disease making the patient unsuited for participation in the study, as judged by the investigator.
  • Treatment for dystonia or spasticity within 3 months of screening (Botox for a focal dystonia is allowed).
  • Substantial neurological symptoms not accounted for by Parkinson's disease, including active seizure disorder, as judged by the investigator.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in Movement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Part III (motor score) in OFF state
Time Frame: From baseline (week 0) to end of study (13 to 104 weeks from baseline)
Measured as score. MDS-UPDRS consists of 4 parts - has 65 items/questions in total. Part III assesses the motor function of the patient at the time of the visit conducted in both the OFF and ON state. Each item will receive a score ranging from 0 to 4, where 0 represents the absence of impairment and 4 represents the highest degree of impairment.
From baseline (week 0) to end of study (13 to 104 weeks from baseline)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in MDS-UPDRS Part III (motor score) in OFF state
Time Frame: From last medication adjustment (between week 0 and week 104) to end of study (13 to 104 weeks from baseline)
Measured as score. MDS-UPDRS consists of 4 parts - has 65 items/questions in total. Part III assesses the motor function of the patient at the time of the visit conducted in both the OFF and ON state. Each item will receive a score ranging from 0 to 4, where 0 represents the absence of impairment and 4 represents the highest degree of impairment.
From last medication adjustment (between week 0 and week 104) to end of study (13 to 104 weeks from baseline)
Is the patient interested in being considered for participation in a cell therapy transplantation study (yes/no)
Time Frame: At end of study (13 to 104 weeks from baseline)
Measured as count of participants
At end of study (13 to 104 weeks from baseline)
