Description of intervention(s) / exposure
This is a randomized, double-blind placebo-controlled, single ascending dose study of K-645 in healthy male participants. This will be the first administration of K-645 to humans.

This study will be composed of 2 panels of 8 participants (Panels A and B), each having Screening (up to 35 days prior to the first dose of study drug), Treatment, and Follow-up (approximately 14 days after their last dose of study medication) stages.

For each panel, the Treatment stage will include up to 4 dosing periods. There will be at least 5 days between the completion of dosing in one period and the start of dosing in the next period. The 14 day Follow-up stage will occur for each panel after completion of their final dosing period.

Participants will participate in either Panel A or Panel B which will be conducted sequentially. Therefore, the first 8 eligible subjects will be assigned to Panel A and the next 8 to Panel B. Panel A will complete all 4 dosing periods before Panel B begins the Treatment stage.

Within each panel, participants will be randomized to treatment with either K-645 or placebo in a 3:1 ratio (6 active: 2 placebo). Participants will be assigned to either K-645 or placebo for the entire study. Therefore, participants randomized to K-645 will receive K-645 in all 4 dosing periods, and those randomized to placebo will receive placebo in all 4 dosing periods. Dosing is double blind meaning that neither the study participants nor the unit staff will know whether a participant is receiving K-645 or placebo in a given treatment period.

All periods for both panels will involve a single administration of K-645 or placebo in the fasted state, except for the final dosing period for Panel B. In Panel B Period 4, one of the dose levels that was administered in the fasted state in a prior period, will be administered following a standardized medium fat breakfast consisting of approximately 750 calories comprised of approximately, 51% carbohydrates, around 18% protein, and 31% fat. The breakfast is expected to include toast, cereals and or hash browns. The standard breakfast will be administered 30 minutes prior to administration of study medication (K-645 or placebo). Participants will have 20 minutes to complete the breakfast.

In all treatment periods, participants will be admitted into the study unit on the day prior to K-645 or placebo administration (Day -1), remain domiciled for at least 24 hours after dosing for safety monitoring and blood sampling, and be discharged on Day 2.

Study medication (K-645 and placebo) will be orally administered as capsules in potencies of 1, 10 and 100mg K-645, and placebo, all of which are visually identical. Capsules are made of Swedish orange hydroxypropyl methylcellulose (HPMC). Compliance will be monitored by site staff witnessing of dosing and will be documented in participant study files.

Planned doses of K-645 are as follows:

Dosing Schedule

Panel A:
Period 1 - 2 mg or placebo
Period 2 - 6 mg or placebo
Period 3 - 18 mg or placebo
Period 4 - 50 mg or placebo

Panel B:
Period 1 - 150 mg or placebo
Period 2 - 300 mg or placebo
Period 3: 500 mg or placebo
Period 4 - 150 mg or placebo

To characterize the safety and tolerability of single rising oral doses of K-645 in healthy male participants.
Timepoint [1] 339106 0
TEAEs are AEs that start or worsen after the first dose of study medication.

For both panels (Panel A and Panel B), TEAEs will be assessed in Period 1 on Day 1 (after dosing) and Day 2, in Periods 2-4 on Day -1, Day 1 and Day 2, and at the post-study visit 14 days after the final dose.

For any subjects who discontinue study medication early, TEAEs will also be assessed at the early termination (ET) visit.

Discontinuation of study medication for a TEAE may occur between start of dosing in Period 1 and completion of dosing in Period 4.
