NCT02274766

Brief Summary

This is a multi-center, randomized, double-blind, placebo-controlled, 2-arm, parallel group study to evaluate the efficacy and safety of ADS-5102 extended release (ER) capsules, an investigational formulation of amantadine, dosed once nightly at bedtime for the treatment of levodopa-induced dyskinesia (LID) in subjects with Parkinson's disease (PD). The novel pharmacokinetic profile of ADS-5102 is expected to achieve i) maximal concentrations in the early morning through mid-day, when LID can be troublesome, and ii) lower concentrations in the evening, potentially reducing the negative impact of amantadine on sleep. This pharmacokinetic profile could enable higher doses to be tolerated with a once-nightly ER formulation than can be tolerated with an immediate-release formulation. The once-nightly dosing regimen may also provide enhanced convenience and compliance. In a previous clinical study, ADS-5102 met its primary endpoint; LID was significantly reduced as measured by the change in UDysRS score over 8 weeks vs. placebo.

Outcome Measures

Primary Outcomes (1)

  • Change in the Unified Dyskinesia Rating Scale (UDysRS) Total Score

    The UDysRS is a dyskinesia rating scale from 0-104; it evaluates involuntary movements associated with PD. A higher score indicates more severe PD. The UDysRS was measured at Baseline and Weeks 2, 4, 8, and 12.

    Baseline to Week 12

Secondary Outcomes (1)

  • Change in the Standardized PD Home Diary (ON Time Without Dyskinesia, ON Time With Troublesome Dyskinesia, OFF Time)

    Baseline to Week 12

Eligibility Criteria

Age30 Years - 85 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Signed a current IRB/REB/IEC-approved informed consent form;
  • Parkinson's disease, per UK Parkinson's Disease Society (UKPDS) Brain Bank Clinical Diagnostic Criteria;
  • On a stable regimen of antiparkinson's medications for at least 30 days prior to screening, including a levodopa preparation administered not less than three times daily, and willing to continue the same doses and regimens during study participation;
  • Following diary training, the subject is willing and able to understand and complete the 24-hour PD home diary (trained caregiver/study partner assistance allowed);
  • Any other current and allowed prescription/non-prescription medications and/or nutritional supplements taken regularly must have been at a stable dose and regimen for at least 30 days prior to screening, and subject must be willing to continue the same doses and regimens during study participation (this criterion does not apply to medications that are being taken pre-study only on an as-needed basis);

You may not qualify if:

  • History of neurosurgical intervention related to Parkinson's disease (e.g. deep brain stimulation);
  • History of seizures within 2 years prior to screening;
  • History of stroke or TIA within 2 years prior to screening;
  • History of cancer within 5 years prior to screening, with the following exceptions: adequately treated non-melanomatous skin cancers, localized bladder cancer, non-metastatic prostate cancer, in situ cervical cancer, or other definitively treated cancer that is considered cured;
  • Presence of cognitive impairment, as evidenced by a Mini-Mental Status Examination (MMSE) score of less than 24 during screening;
  • If female, is pregnant or lactating;
  • If a sexually active female, is not surgically sterile or at least 2 years post-menopausal, or does not agree to utilize an effective method of contraception from screening through at least 4 weeks after the completion of study treatment, using one of the following: barrier methods (diaphragm or partner using condoms plus use of spermicidal jelly or foam, preferably double-barrier methods); oral or implanted hormonal contraceptive; intrauterine device (IUD); or vasectomized male partner;
  • Treatment with an investigational drug or device within 30 days prior to screening;
  • Treatment with an investigational biologic within 6 months prior to screening;
  • Current participation in another clinical trial;
