A Safety, Tolerability and Levodopa Pharmacokinetics Study of Repeated ND0612 in Parkinson's Disease Patients (ND0612/003)

July 8, 2026 updated by: NeuroDerm Ltd.

A Phase IIa Multicenter, Randomized, Double-blind, Placebo-controlled Study Followed by an Open-label Period, to Evaluate the Safety, Tolerability, and Levodopa Pharmacokinetics in Levodopa-treated Parkinson's Disease Patients With Motor Fluctuations, Administered With Repeated Subcutaneous ND0612

This is a randomized, placebo-controlled, double-blind, 2-period study evaluating the safety and pharmacokinetics (PK) of ND0612 in Parkinson's disease (PD) patients on an optimized oral levodopa (LD) regimen and experiencing ≥2 h/day of OFF time. Safety and tolerability, PK profile, pump usability, and the potential clinical effect of ND0612 will be explored in subjects with PD and motor fluctuations.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

During Period 1, patients continued on their current standard of care (SoC) levodopa/carbidopa (LD/CD) and were randomized at 2:1 ratio to 14 days of adjunct treatment with ND0612 (daily LD/CD dose of 270/63 mg) or placebo infusion. During Period 2, patients were randomized to receive 7 days open-label treatment with ND0612 or ND0612 plus oral entacapone. Patients then entered a 4-week safety follow-up period.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

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

30 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  1. Men and women with idiopathic PD whose diagnosis was confirmed by presence of at least two of the cardinal signs (resting tremor, bradykinesia, rigidity) and lacking any other known or suspected cause of parkinsonism.
  2. Patients who experienced motor fluctuations averaging at least two hours daily in the "OFF" state during the waking hours (including morning akinesia), corresponding to the end-of-dose deterioration phenomenon ("wearing off") confirmed by the baseline home diaries.
  3. Modified Hoehn and Yahr stage < 5 in the "OFF" state.
  4. Patients who were taking optimized LD/decarboxylase inhibitor therapy (based on the investigator's judgment) that was stable for at least 14 days prior to baseline. Patients were to receive at least three daily doses of LD (which could include a bedtime dose) with at least three hours between doses.
  5. Patients treated with dopaminergic agonists and other anti-PD drugs were to be on stable doses for at least 30 days prior to baseline and those doses were to remain constant throughout the study period.
  6. Women who were postmenopausal, surgically sterilized, or using adequate birth control. Women of childbearing potential were to have a negative pregnancy test (beta human chorionic gonadotropin [hCG] serum) at screening.
  7. Patients between the ages of 30 and 80.
  8. Patients willing and able to give informed consent.
  9. Patients and/or caregivers able to understand and follow instructions for use of SC delivery pump.
  10. Patients who demonstrated the ability to keep accurate diaries of PD symptoms (ON-OFF diaries).

Exclusion Criteria:

  1. Patients treated with controlled release formulation of LD/CD. (Note: Patients treated with Entacapone, Tolcapone, or Stalevo were allowed to participate in Period 1 but were excluded from Period 2 participation)
  2. Patients with a clinically significant or unstable medical or surgical condition which would preclude safe and complete study participation. Such conditions may include gastrointestinal, cardiovascular, pulmonary, hepatic, renal, or metabolic diseases or malignancies as determined by medical history, physical exam, laboratory tests, or ECG.
  3. History of melanoma or significant skin disorders.
  4. Patients with significant cognitive impairment as defined by a MMSE score of < 25.
  5. Patients treated with dopaminergic agonists, anticholinergics, monoamine oxidase (MAO)-B inhibitors, or antipsychotics that need dose adjustment in the 30 days prior to Study Baseline.
  6. Patients with clinically significant psychiatric illness, including major depression (according to Diagnostic and Statistical Manual of Mental Disorders [DSM] IV criteria for major depressive episode) or other problems that might compromise their ability to provide consent or participate fully in the study.
  7. Patients with a history of alcohol or substance abuse within the past two years.
  8. Patients who have taken experimental medications within 60 days prior to baseline.
  9. Patients who have undergone a neurosurgical intervention for PD (e.g. pallidotomy, thalamotomy, transplantation, or deep brain stimulation procedures).
  10. Patients with severe disabling dyskinesias.
  11. Patients with hearing, visual or motor impairments that prevent them from using the pump or reacting effectively to errors.
