Ulcerative Colitis | Drug: LIV001 Drug: Placebo | Phase 1 |
The study will be conducted in 2 parts. Approximately 36 subjects are planned to be enrolled into the study.
- In Part A (SAD), approximately 18 healthy subjects will be enrolled in 2 sequential cohorts (Cohorts SAD1 and SAD2) and randomized 2:1 to receive a single dose of investigational product (IP) (LIV001 or placebo)
- In Part B (MAD), approximately 18 healthy subjects will be enrolled into 2 sequential cohorts (Cohorts MAD1 and MAD2) and randomized 2:1 to receive LIV001 or placebo for 14 days.
Oversight of the study will be provided by a Safety review committee (SRC) comprising the Principal Investigator (PI), the local Medical Monitor (MM), and a representative of the Sponsor, at a minimum.

Ages Eligible for Study: | 18 Years to 60 Years (Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | Yes |
Inclusion Criteria:
Part A (SAD) and Part B (MAD)
- Male or female, aged 18 to 60 years (inclusive) at Screening.
- Body mass index (BMI) 18 kg/m2 to ≤ 32 kg/m2 (inclusive) at Screening.
- Subject is generally healthy, in the opinion of the Investigator, based on assessment of medical history, physical examination, vital signs, ECG, laboratory parameters, and other relevant tests conducted at Screening.
- Subject has clinical laboratory values within normal range, as specified by the testing laboratory, at Screening and Day 1, unless deemed not clinically significant by the Investigator or delegate.
- Nonsmoker or casual smoker who agrees to smoke ≤ 5 cigarettes per week (includes e-cigarettes and other nicotine and tobacco products) during the study, including follow-up, and is willing to abstain from smoking/nicotine products during the CTU confinement period(s) and for ≥ 5 days before each study visit.
- Male and female must agree to contraceptive usage as per protocol from Screening through 90 days after final dose of IP.
- Willing and able to comply with all study-related procedures and assessments, including attending visits to the CTU.
- Able to read and understand, and willing to sign the ICF.
- Willing to allow storage of blood and fecal samples for future studies of genetic make-up.
Exclusion Criteria:
Part A (SAD) and Part B (MAD)
- Female subjects who are pregnant or lactating.
- Abnormal ECG findings at Screening or Day -1 that are considered by the Investigator or designee to be clinically significant.
- Has taken prescription medication (including antibiotics) within 14 days or over-the-counter (OTC) non-prescription medication, herbal remedies, vitamins or minerals, probiotics (foods containing probiotics are permitted), and yeast supplements (eg, Mutaflor®, Bioflor®) within 7 days prior to the first dose of IP that may, in the opinion of the Investigator, compromise subject safety or interfere with study procedures or data validity. Subjects may be rescreened after a washout period of 14 days for prescription medication or 7 days for OTC products. Use of oral contraceptives and paracetamol (1 to 2 therapeutic doses per week, ie, up to 2 g per week) and/or nonsteroidal anti-inflammatory drugs for symptomatic relief of minor symptoms is permitted.
- Functional gastrointestinal disorders, eg, irritable bowel syndrome, functional heartburn, functional nausea, functional dyspepsia, functional constipation, and functional diarrhea.
- Substance abuse-related disorder or a history of drug, alcohol (ie, regular use of > 21 units of alcohol per week) and/or substance abuse deemed significant by the Investigator.
- Has taken any IP or received IP in another clinical trial within 30 days prior to the first dose of IP or 5 half-lives, whichever is longer.
- History of significant hypersensitivity or severe allergic or anaphylactic reactions involving any drug (including ampicillin, clindamycin or imipenem), any constituent of the IP (LIV001 or its excipients), food or other precipitating agent (eg, bee sting). Subjects with clinically stable mild allergic conditions such as hay fever and mild eczema may be enrolled at the discretion of the Investigator.
- Positive test for human immunodeficiency virus (HIV), hepatitis B surface antigen (HBsAg), or hepatitis C virus antibody (anti-HCV) at Screening.
- Positive screen for drugs of abuse at Screening or Day -1, or positive screen for alcohol on Day -1.
- Subject is, in the opinion of the Investigator, unlikely to comply with the clinical study protocol or is unsuitable for any other reason.
