Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
In Part A (SAD) cohorts will consist of eight (8) subjects, six (6) of whom will receive treatment with IkT-148009 and two (2) with matching placebo. Sentinel dosing will be employed on the first day of each cohort, with one subject randomized to receive IkT-148009 and the other placebo. These two subjects in each cohort will be monitored for 48 hours after dosing before deciding to dose the remainder of the cohort. 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 administer drug to the sentinel pair for the next cohort. Each cohort will be dosed at approximately weekly intervals to allow adequate time for collection and review of safety and PK data.
A Safety Review Committee (SRC) will evaluate all available safety, tolerability, and PK data for each cohort. Escalation to a next dose will be undertaken only after these data have been reviewed by the SRC and agreement reached that it is safe to increase the dose. The SRC will not receive any unblinded PK data unless they agree to unblind a subject and/or cohort based on the completed safety review.
In Part B (MAD) cohorts will consist of eight (8) subjects, six (6) of whom will receive treatment with IkT-148009 and two (2) with matching placebo daily for up to seven consecutive days. Subjects in each cohort will be observed for 48 hours after their last dose before deciding to initiate the next (higher dose) cohort. Each cohort will be dosed at approximately weekly intervals in order to allow adequate time for collection and review of safety and PK data. At the discretion of the SRC, MAD cohorts may be added consisting of eligible participants with Parkinson's Disease (Part C).
In Part C (MAD with Parkinson\'s Disease) eligible PD participants will arrive the evening before initiation of study drug dosing. No Parkinsonism medications will be given after midnight, the following morning potential participants will be clinically assessed in the practically-defined OFF state using MDS-UPDRS Part III. Cohorts will consist of eight (8) subjects, six (6) of whom will receive treatment with IkT-148009 and two (2) with matching placebo daily for up to seven consecutive days. Subjects in each cohort will be observed for 48 hours after their last dose before deciding to initiate the next (higher dose) cohort. Each cohort will be dosed at approximately weekly intervals in order to allow adequate time for collection and review of safety and PK data.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
2\. 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.
4\. Mini Mental State Examination (MMSE) ≥ 28 at Screening (V1) and Baseline (V2).
5\. 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. Body weight ≥ 45 kg at screening and baseline visits. Body Mass Index (BMI) ≥ 18 and ≤30 kg/m2 at screening.
6\. 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.
7\. 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.
8\. 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:
9\. MMSE ≥ 26 at screening (V1) and Baseline (V2) 10. Diagnosis of Parkinson's Disease (consistent with the UK PD Society Brain Bank Criteria for the Diagnosis of PD), with bradykinesia and a clear motor response to levodopa.
11\. Hoehn \& Yahr staging of 3 or less in the ON state. 12. Good clinical response to levodopa as judged by participant and investigator.
13\. Stable doses of all PD medications for at least 4 weeks prior to Screening. 14. Approved by an Enrollment Authorization Committee (EAC).
Exclusion Criteria
2\. Clinically significant abnormal findings on physical examination or 12-lead electrocardiogram (ECG) at the screening or admission visits. NOTE: QTcF interval of \> 450 msec in males or \> 470 msec in females will be the basis for exclusion from the study. Safety ECG may be repeated for confirmatory purposes if initial values obtained exceed the limits specified.
3\. 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).
4\. For optional lumbar puncture: participants with bleeding disorders, relevant lab abnormalities (Screening INR greater than 1.4, platelets less than 50), relevant blood dyscrasias, 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.
5\. eGFR \< 60 mL/min 6. Creatinine, Amylase and/or Lipase \> ULN 7. Any malignancy in the 5 years prior to screening excluding basal cell carcinoma or squamous cell carcinoma of the skin or cervical carcinoma in situ that have been successfully treated.

Subjects that consume three glasses of alcoholic beverages per day but less than 14 glasses per week may be enrolled at the discretion of the Investigator. Positive screens for alcohol or controlled substances at the screening or admission visits will disqualify a subject from study participation.
10\. Any subject with known hypersensitivity to IkT-148009.
11\. Donation of blood or acute loss of blood within 60 days prior to screening visit.
12\. Any subject who has received treatment with an investigational drug during the 30 days prior to screening.
