Brief Summary:
This is a phase 2 study, randomized, double-blind, placebo-controlled, multicenter study of oral CVN424 at two dose levels (low-dose and high-dose) in Parkinson's disease (PD) patients with motor fluctuations.
| Condition or disease | Intervention/treatment | Phase |
|---|---|---|
| Parkinson Disease | Drug: CVN424 Low Dose Drug: CVN424 High Dose Drug: Placebo | Phase 2 |
Approximately 135 male and female subjects with Parkinson's disease, on a stable dosage of levodopa but with an average of ≥ 2 h total OFF time/day and not less than 1 h per day, will be enrolled. Following baseline safety and efficacy assessments, subjects will be randomized to receive once-daily doses of either low-dose CVN424, high-dose CVN424, or matching placebo. All subjects not randomized to placebo will initiate treatment with a low-dose of CVN424 on Day 1; the low-dose arm will continue to receive their low dose each day, while the high-dose arm will increase their daily dosage to the high-dose CVN424 beginning on Day 8 ±2 days and continuing thereafter. Study drug will be self-administered each morning as an oral suspension. Subjects will continue their other PD medications.

Primary Outcome Measures :
- Number of Subjects who experience Adverse Events related to study drug [ Time Frame: Baseline through 30 days after the last dose ]AEs with onset or exacerbation up until dosing on Day 1 will be scored as pretreatment events (PTEs), and AEs that occur from first dosing until 30 days after the last dose will be captured as a treatment-emergent AE (TEAE).
Secondary Outcome Measures :
- Number of subjects with abnormal and clinically significant (CS) safety laboratory test results, ECG test results, or vital sign measurements [ Time Frame: Baseline through Day 27 ]Twelve-lead ECGs will be recorded using an ECG machine that automatically calculates the heart rate and measures PR interval, RR interval, QRS interval, QT interval, and QTcF and QTcB (Fridericia's and Bazett's correction method) intervals. Observed values and changes from baseline in quantitative ECG parameters will be summarized by placebo, and each CVN424 dose level.
- Change from baseline in 2-day average OFF time at Day 27 as recorded in the Patient Motor Diary [ Time Frame: Baseline through Day 27 ]Completion of the patient motor diary over the two days prior to each visit.

Criteria
Inclusion Criteria:
- Male or female adult who is 30 to 80 years of age inclusive at study entry.
- Has idiopathic Parkinson's disease, Hoehn and Yahr stages 2-4, and is on a stable dosage of levodopa.
- Experiences an average of at least 2 h total OFF time/day, and at least 1 h each day, per Patient Motor Diary over 2 days during Screening assessment.
- The subject signs and dates a written informed consent form (ICF) and any required privacy authorization prior to the initiation of any study procedures.
Exclusion Criteria:
- Has atypical parkinsonism, severe disabling dyskinesia, or severe motor fluctuations that the investigator considers likely to interfere with study participation or assessments, or history of implant for Deep Brain Stimulation.
- Poor concordance (<75%) of self-report with site rater on in-clinic Screening period Patient Motor Diary. Subjects with low concordance may be retested after further instruction, at investigator's discretion.
- Screening period Patient Motor Diary scored at-home over 2 days demonstrates unacceptable quality of the diary, with more than 4 errors per day. (Assistance from caregivers is permitted if they also will be providing assistance with home Patient Motor Diary entries for Day 15 and 27 efficacy assessments.) Subjects with more than 4 errors per day may be retested after further instruction, at investigator's discretion.
- Body mass index (BMI) at Screening <18.0 or >35.0 kg/m2, inclusive.
- Subject has evidence of Clinically significant neurologic or other disorder or impairment that, in opinion of Investigator, is reasonably expected to impact the ability of the subject to participate or to confound the study results.
- Subject has current or recent (within 6 months) gastrointestinal disease that would be expected to influence the absorption of drugs (i.e., a history of malabsorption, any surgical intervention known to impact absorption [e.g., bariatric surgery or bowel resection]).
- Subject has a history of cancer or other malignancy, with the exception of low-grade cervical intraepithelial neoplasia, low-grade (low-risk) prostate cancer, or 5-year cancer-free survivors of basal or squamous cell carcinoma, higher-grade cervical intraepithelial neoplasia or prostate cancer.
- Has a history of human immunodeficiency virus (HIV) infection.
- Subject has a supine blood pressure outside the ranges of 80 to 160 mm Hg for systolic and 50 to 100 mm Hg for diastolic, confirmed with up to two repeat tests, at the Screening Visit; or symptomatic orthostatic hypotension, in the opinion of the investigator.
- Subject has a resting heart rate outside the range 50 to 100 bpm, confirmed with up to two repeat tests, at the Screening Visit.
- Positive urine result for illegal drugs (except cannabis) at Screening, or history of illegal drug use (except cannabis) or alcohol abuse within 1 year prior to the Screening Visit.
- Subject has received any investigational compound (defined as a drug that has not been FDA-approved) within 30 days prior to the first dose of study medication, or within 5 half-lives of the investigational compound, whichever is greater.
- Subject has, within the prior month, ingested any excluded medication, supplements, or food products listed in the Excluded Medications and Dietary Products table as listed in Table 2.
- Male subjects who do not agree to all the following rules: when sexually active with female partner(s) of childbearing potential during the study and for 12 weeks after the last dose of study drug: a) use an acceptable method of birth control (condom with spermicide or surgical sterilization) and b) refrain from sexual activity with female partners who do not use an acceptable method of birth control. Barrier contraception (condom with spermicide) must be used by all male subjects who were not surgically sterilized at least 90 days prior to screening. Male subjects must also agree to refrain from sperm donation during the study and until 12 weeks after the last dose of study drug.
- Female subjects who are pregnant or breastfeeding or plan to become pregnant or donate ova during the study or for 30 days after the last dose of study drug. Women of childbearing potential (WOCBP) also must be practicing an adequate method of birth control (e.g., oral or parenteral contraceptives, intrauterine device, barrier, abstinence).
- Risk of suicide according to the investigator's clinical judgment or has made a suicide attempt in the previous 3 years.
