Brief summary
This is a double-blind, randomized, placebo-controlled study which is subdivided in 2 parts, Part 1 (SAD) and Part 2 (MAD). Decisions about how and when to move between cohorts will be based on reviews of the available blinded safety data and available pharmacokinetic (PK) data; this data will be reviewed by a prespecified Safety Review Committee (SRC). In Part 1, healthy volunteers will be enrolled to receive single ascending doses of LTSE-2578 or placebo. In Part 2, healthy volunteers will be enrolled to receive once or twice daily doses of LTSE-2578 or placebo for fourteen consecutive days.
Interventions
The study will be conducted in 2 parts:
Part 1: Single ascending dose (SAD)
Part 2: Multiple ascending dose (MAD)
Decisions about how and when to move between cohorts will be based on reviews of the available safety data (blinded) and pharmacokinetic data.
Part 1: Each cohort will enrol 8 participants with 6 participants randomized to receive LTSE-2578 and 2 participants randomized to receive placebo on Day 1. There will be 5 cohorts and LTSE-2578 oral tablet will be administered at dose lev

Part 1: Each cohort will enrol 8 participants with 6 participants randomized to receive LTSE-2578 and 2 participants randomized to receive placebo on Day 1. There will be 5 cohorts and LTSE-2578 oral tablet will be administered at dose levels in the range of 6mg - 250mg. SAD Cohort 4 – food effect cohort: Single oral dose of LTSE-2578 or placebo administered on Day 1 under fasted conditions and another dose administered on Day 5 under fed conditions (total of 2 doses). Part 2: LTSE-2578 oral tablet administered twice daily for 14 days at up to 3 dose levels (3 cohorts) in the range from 20 mg to up to 200 mg (total daily dose; actual dosage to be determined based on data from Part 1 and the preceding cohorts in Part 2). Each cohort will enrol 8 participants with 6 participants randomized to receive LTSE-2578 and 2 participants randomized to receive placebo. Study drug will be administered at the study site by trained study site personnel to ensure compliance.

Inclusion criteria
1. Adult males and females, 18 to 65 years of age (inclusive) at screening. 2. Body mass index (BMI) greater than or equal to 18.0 and less than or equal to 30.0 kg/m2, with a body weight (to 1 decimal place) greater than or equal to 40 kg at screening. 3. Medically healthy (in the opinion of the Investigator) at screening, as determined by pre-study medical history, and without clinically significant abnormalities including: a. Physical examination without any clinically relevant findings; b. Systolic blood pressure in the range of 90 to 140 mmHg and diastolic blood pressure in the range of 50 to 90 mmHg after 5 minutes in supine or semi-supine position. c. Pulse rate in the range of 40 to 100 bpm after 5 minutes rest in supine or semi-supine position. d. Body temperature (tympanic), between 35.5°C and 37.5°C. e. Electrocardiogram (ECG) without clinically significant abnormalities including QRS interval >120 msec on the screening ECG (measurements are the mean of 3 ECGs), QT interval corrected for Fredericia (QTcF) <450 msec for male subjects and <470 msec for female subjects. f. No clinically significant findings in serum chemistry, haematology, coagulation and urinalysis tests including the following specific findings: i. Alanine aminotransferase (ALT) <1.5 x ULN, aspartate aminotransferase (AST) <1.5 x ULN, gamma-glutamyl transferase (GGT) <1.5 x ULN, or alkaline phosphatase <1.5 x ULN . 4. Female volunteers (Childbearing or non-childbearing potential): a. Non-childbearing potential is defined as surgically sterilized (hysterectomy, bilateral salpingectomy, bilateral oophorectomy) at least 6 weeks before the screening visit or postmenopausal (where postmenopausal is defined as no menses for 12 months without an alternative medical cause and a follicle-stimulating hormone (FSH) level consistent with postmenopausal status, per local laboratory guidelines), or b. If of child-bearing potential, must: i. Have a negative pregnancy test at the screening visit and on admission to the clinic on Day-1. ii. Agree not to attempt to become pregnant or donate ova from signing the consent form until at least 90 days after the last dose of study drug. iii. If not exclusively in a same-sex relationship or abstinent as a committed lifestyle, agree to use adequate contraception (defined as use of a condom by the male partner combined with use of a highly effective method of contraception from one month prior to screening until at least 90 days after the last dose of study drug. 5. Male volunteers, must: a. Agree not to donate sperm from signing the consent form until at least 90 days after the last dose of study drug. b. If engaging in sexual intercourse with a female partner who could become pregnant, agree to use adequate contraception (defined as use of a condom combined with use of a highly effective method of contraception from signing the consent form until at least 90 days after the last dose of study drug. c. If engaging in sexual intercourse with a female partner who is not of childbearing potential or a same-sex partner, agree to use a condom from signing the consent form until at least 90 days after the last dose of study drug.
Exclusion criteria
1. Known hypersensitivity to any of the study drug ingredients. 2. Demonstrated clinically significant (required intervention, e.g., emergency room visit, epinephrine administration) allergic reactions (e.g., food, drug, or atopic reactions, asthmatic episodes) which, in the opinion of the Investigator, would interfere with the volunteer’s ability to participate in the trial. 3. History or presence of clinically significant cardiovascular, pulmonary, hepatic, renal, hematologic, GI, endocrine, immunologic, dermatologic, psychiatric or neurological disease/disorder, including any acute illness, within the past 3 months determined by the Investigator to be clinically relevant. 4.
