About
Primary study objectives in Parts A and B To determine the Maximum Tolerable Dose(MTD) of the study drug (repeated or single dose).
Endpoint: • Adverse event(AEs), including objective and subjective symptoms, after the IP dosing as well as physical examinations, vital signs, ECGs, and laboratory tests findings related to the IP dosing
• Dose-limiting toxicities (DLTs)
Justification for endpoints: The safety will be assessed comprehensively by performing safety assessment and evaluating relevant variables by dose group.
The tolerability will be assessed in DLT analysis set. In a first-in-human clinical trial, tolerability of the drug administered is usually assessed through determination of dose-limiting toxicity (DLT). An accurate dose proportionality of toxicity was not observed, but toxicity was found at high doses, not at low doses following IV and oral administrations, except transdermal treatment. Thus, a relationship between toxicity and doses was confirmed.
In addition, HY209 showed a dose dependence in some efficacy endpoints, including dose-dependent inhibition of release of Tumor Necrosis Factor(TNF)-α and Il-1β, key inflammation factors related to inflammatory bowel disease. Thus, evaluating the occurrence of DLTs through sequential dose escalation is determined appropriate to assess the tolerability and safety of HY209.

Inclusion criteria
Exclusion criteria
Clinically significant diseases or past history that precludes the study participation in the investigator's opinion
Occurrence of any diseases (illnesses) within 1 week prior to start of the IP dosing [e.g., flu epidemic or common cold, fever ≥ 38℃]). (However, when the disease is resolved in a short period of time, their study participation can be determined through a follow-up test after treatment.)
Unable or unwilling to take tablets
The following diseases and health conditions that may affect the pharmacokinetics (PK) of the IP, including absorption
Rare hereditary problems of galactose intolerance, the Lapp lactose deficiency, or glucose galactose malabsorption
The following laboratory test results at screening (However, for liver tests, any test results that are considered to be caused by clinically meaningless transient changes or one-time alcohol consumption and night-shift work and other lifestyle can be finally confirmed through follow-up tests after the correction)
Systolic blood pressure (BP) ≥ 150 mmHg or ≤ 100 mmHg, or diastolic BP ≥ 100 mmHg or ≤ 60 mmHg in the vital signs as measured in a sitting position after taking a rest for at least 3 minutes
Pulse rate < 50 beats/min (bpm) or > 90 bpm when measured in a sitting position after taking a rest for at least 3 minutes; or < 45 bpm when (1) a normal thyroid function is confirmed with interview, physical examinations, and Thyroid stimulating Hormone(TSH) tests and (2) there is no clinical symptom of bradycardia (orthostatic hypotension and vertigo).
Patients with clinically significant arrhythmia in the ECGs in the investigator's opinion (not applicable for the first degree atrioventricular(AV) block associated with the heart rate that meet the inclusion criteria)
Clinically significant findings in 12-lead ECGs at screening
History of malignancy, except for the following cases
Patients with the following active infections:
Persistent alcohol consumption within 6 months prior to the first dose (exceeding 21 units/week, 1 unit = 10 g = 12.5 mL of pure alcohol) or unable to abstain from consuming alcohol throughout the study period from 72 hours prior to the first dose of the study drug to the end of study (the final visit) [e.g., 1 cup (250 mL) of beer (5%) = 1 glass (50 mL) of 10 g soju (20%) = 1 glass (125 mL) of 8 g wine (12%) = 12 g]
Smokers (subjects who quit smoking at least 6 months prior to screening and have negative urine cotinine test at screening or who have never smoked are eligible)
Whole blood donation or loss of substantial amount of blood within 2 months or apheresis within 1 month, or blood transfusion within 1 month prior to the first dose
Past history of hypersensitivity to any components of the IP
Subjects who have received any of the following drugs prior to the study participation and the required washout period has not passed
History of substance or alcohol abuse or addiction within 2 years prior to the start of the study drug or positive screening results for alcohol, smoking, or abusive drugs [e.g., cotinine, amphetamines, barbiturates, benzodiazepines, cannabinoids, cocaine or opioids, tricyclic antidepressants] at screening
Males who do not agree to use effective contraceptions during the study period and up to 3 months after the last dose of the study drug
Persons who do not agree to refrain from donating their sperms during the study period and at least 3 months after the last dose of the study drug
Persons who answer "Yes" to any of the questions in the Columbia-Suicide Severity Rating Scale (C-SSRS) within the past 12 months at screening (for Part B only)
Persons who are participating in another clinical study or have taken a drug in another clinical study or bioequivalence study within 6 months prior to the first dose of the study drug (however, to determine the end of other study participation, the next day of the last dose will be counted as Day 1.)
