About
A study of an investigational drug to see how it affects the people with Parkinson's Disease complicated by motor fluctuations ("OFF" Episodes) compared to an approved drug used to treat people with Parkinson's Disease complicated by motor fluctuations ("OFF" Episodes)
Full description
An Open-Label, Randomized, Crossover Trial utilizing a Single-Blinded Rater to evaluate APL-130277 compared to s.c. Apomorphine in Levodopa Responsive Subjects with Parkinson's Disease Complicated by Motor Fluctuations.
PART A consists of an open label, crossover titration phase where eligible subjects will be randomized to 1 of 2 treatment sequences in a 1:1 ratio to Sublingual APL-130277 followed by subcutaneous apomorphine or subcutaneous apomorphine followed by sublingual APL-130277. Subjects will undergo dose titration with the first study treatment (APL-130277 or sc apomorphine) to tolerance and effect, ie, the tolerable dose that turns the subject from the practically defined "OFF" state to the full "ON" state as determined by both the Investigator and subject. The subject will then be crossed over to the other study treatment (APL-130277 or subcutaneous apomorphine) and similarly titrated to tolerance and effect. These determined doses of APL-130277 and subcutaneous apomorphine will be used during PART B.
PART B consists of an open-label, crossover treatment period where subjects will be randomized to one of the study treatment for 4 weeks, then be crossed over to the other study treatment (APL-130277 or sc apomorphine) for additional 4-weeks of open-label treatment. Subjects return to the clinic for safety and efficacy assessments throughout the treatment period.
This study is designed to test the superiority of sublingually administered APL-130277 against subcutaneously injected apomorphine (APO-go) for the treatment of "OFF" episodes in patients with Parkinson's Disease, as measured by the change from pre-dose to 90 minutes post-dose in MDS UPDRS Part III score in Part B after 4 weeks of dosing in each crossover period.

Inclusion criteria
- The subject (and caregiver, if applicable) must be fully informed of and understand the objectives, procedures, and possible benefits and risks of the study, and give written informed consent prior to performing any study related activities.
- Male or female ≥ 18 years of age.
- Clinical diagnosis of Idiopathic Parkinson's disease (PD), consistent with UK Brain Bank Criteria (excluding the "more than one affected relative" criterion).
- Clinically meaningful response to levodopa (L-Dopa), as determined by the Investigator.
- Subjects at screening must demonstrate an adequate L-Dopa response on the Movement Disorder Society Unified Parkinson's Disease Rating Scale (MDS UPDRS) Part III in the "ON" state compared to the MDS UPDRS Part III in the "OFF" state and on the Hoehn and Yahr, as determined during the review by Enrollment Adjudication Committee (EAC), Sponsor, and Medical Monitor.
- Receiving stable doses of L Dopa/carbidopa and/or L Dopa/benserazide and/or L Dopa/carbidopa/entacapone (immediate or chronic release) administered at least 4 times per day OR Rytary™ administered at least 3 times per day for at least 4 weeks before the initial screening Visit (SV1). Adjunctive PD medication regimens are permitted but must be maintained at a stable dose for at least 4 weeks prior to SV1 with the exception of monoamine oxidase B (MAO B) inhibitors, which must be maintained at a stable level for at least 8 weeks prior to SV1.
- No planned medication change(s) or surgical intervention anticipated during the course of study.
- Subjects must experience at least one well defined "OFF" episode per day and have a total daily "OFF" time duration of > 2 hours during the waking day, based on judgment of physician and subject self assessment.
- Subject must have predictable morning "OFF" periods, based on judgment of physician and subject self assessment.
- Subject, and where appropriate caregiver, must be trained in completing the home dosing diaries and able to recognize "ON" and "OFF" states.
- Stage III or less on the modified Hoehn and Yahr scale in the "ON" state.
- Mini-Mental State Examination (MMSE) score > 25.
- Female subject of childbearing potential and male subject with female partner of childbearing potential must agree to either remain abstinent or use adequate and reliable contraception throughout the study and for at least 7 days after the last dose of study drug has been taken. Note: Continued use of adequate and reliable contraception is recommended through 30 days after study completion.
- Willing and able to comply with scheduled visits, treatment plan, laboratory tests, and other study related procedures to complete the study.
- Must be approved as a satisfactory candidate by the Enrollment Adjudication Committee (EAC), Medical Monitor, and Sponsor.
Exclusion criteria
-
Atypical or secondary parkinsonism.
-
Major focal brain disorders including malignancy or stroke.
