Brief Summary

This study investigates the safety and tolerability of drug IkT-148009 in healthy elderly volunteers (55 to 70 years old). This first-in-human study is designed in 3 parts. In Part A, healthy participants will take a single, oral dose of IkT-148009 or placebo. Part A participants will be at the study site for approximately 4 days. In Part B, healthy participants will take an oral dose of IkT-148009 once a day for 7 days. Part B participants will be at the study site for approximately 12 days. In Part C, Parkinson\'s patients will take an oral dose of IkT-148009 once a day for 7 days. Part C participants will be at the study site for approximately 12 days.

  • \. Men or women aged 55 to 70 years (both inclusive) of any race. 3. Subjects must be otherwise healthy and ambulatory, with no history or evidence of clinically relevant medical disorders as determined by the Investigator in consultation with the Sponsor.
  • \. Mini Mental State Examination (MMSE) ≥ 28 at Screening (V1) and Baseline (V2).
  • \. Physical examination, clinical laboratory values, vital signs (as defined in the CRU standard operating procedure \[SOP\]), and the electrocardiogram (ECGs) are clinically acceptable to the Investigator.

  • \. Female subjects must be postmenopausal (12 months without menses and confirmed by follicle stimulating hormone \[FSH\] \> 40 mIU/mL) or surgically sterile (hysterectomy or bilateral oophorectomy) or sterile for other medical reason (i.e., able to document premature low ovarian reserve, birth defect, other). Women who are several years postmenopausal may be considered for enrollment even with \[FSH\] below this threshold.
  • \. Male subjects must agree to practice an acceptable method of highly effective birth control from the Screening visit, while on study and for 7 days after receiving the last dose of study drug. Highly effective methods of birth control include sexual abstinence; vasectomy; or a condom with spermicide (men) in combination with their partner's highly effective method.
  • \. Males must be willing to abstain from sperm donation from the screening visit, while on study and through 30 days after receiving the last dose of study drug.
  • Part C:
  • Participants must be eligible as in Part A and B, with the following differences/additions:

  • \. Stable doses of all PD medications for at least 4 weeks prior to Screening. 14. Approved by an Enrollment Authorization Committee (EAC).

You may not qualify if:

  • \. Clinically significant abnormal values for hematology, clinical chemistry or urinalysis at the screening and admission visits. Abnormalities considered to be non-clinically significant by the Investigator are acceptable.
  • \. Significant history (within six months prior to receiving the study drug) and/or presence of clinically significant medical, surgical or psychiatric disorder. Subjects with co-morbid conditions that are stable and controlled may remain eligible (stable defined as no change in the dose or frequency of medications over the prior three months).
  • \.

  • \. Donation of blood or acute loss of blood within 60 days prior to screening visit.
  • \. Any subject who has received treatment with an investigational drug during the 30 days prior to screening.

  • \. Any subject unwilling or unable to comply with study procedures.
  • and in addition for Part C:
  • \. For optional lumbar puncture: participants with bleeding disorders, relevant lab abnormalities (Screening INR greater than 1.4, platelets less than 50), prior intolerance of LP, anatomical reasons preventing safe or successful collection of fluid (skin infection at site of puncture, relevant spine surgery, spinal deformity, etc), known intracranial space-occupying lesions with mass effect, posterior fossa masses, or relevant brain malformations (Arnold-Chiari malformation, etc), exam findings suggestive of increased intracranial pressure, or known allergy/sensitivity to lidocaine or its derivatives will not be eligible.
  • \. Diagnosis of secondary or atypical parkinsonism 17. Prior neurosurgery for PD or treatment with DUODOPA or infused apomorphine 18. Concurrent use of neuroleptic medications or other dopamine antagonists. 19. Severe or disabling fluctuations or dyskinesias that would, in the opinion of the investigator, interfere with completion of the study 20. Clinically significant hallucinations or delusions that, in the opinion of the investigator or EAC, may preclude completion of the study 21. Clinically significant orthostatic hypotension that, in the opinion of the investigator, may preclude completion of the study 22.

Intervention Model
SEQUENTIAL
Model Details: Sentinel dosing will be employed for each cohort in Part A, with one subject randomized to receive IkT-148009 and the other placebo on the first day. These two subjects in each cohort will be monitored for 48 hours after dosing before deciding to dose the remainder of the cohort. As such, the other six subjects in the first cohort will be dosed approximately 48 hours later. Each cohort will be monitored for at least 48 hours before deciding whether to sentinel pair in the next (higher dose) cohort, and each cohort will be dosed at approximately monthly intervals in order to allow adequate time for collection and review of safety and PK data. In Part B, 8 patients will be 3:1 randomized to placebo and dosed once per day for 7 days. In Part C, 8 patients will be 3:1 randomized to placebo and dosed once per day for 7 dayts.
