Clinical Trial Summary

The purpose of this study is to assess the safety, tolerability and pharmacokinetics of single and multiple intravenous doses of BWC0977 when administered to healthy adult volunteers.


Description:

This Phase 1 study is designed to assess the safety, tolerabilty and pharmcokinetics of single and multiple intravenous doses of BWC0977 when administered to healthy adult volunteers. This is a randomized double-blind, placebo-controlled, ascending dose, multi-cohort trial. A total of 64 healthy volunteers are expected to be enrolled into 8 Cohorts. The study will be conducted in two phases: A single ascending dose (SAD) phase, followed by a multiple ascending dose (MAD) phase. In SAD, participants in Cohorts 1 - 5 will receive one dose of BWC0977 or placebo. In MAD, participants in Cohorts 6 - 8 will receive multiple doses of BWC0977 or placebo for 10 consecutive days at a dose deemed safe and tolerable as determined in the preceding SAD Cohorts. In both parts sequential cohorts will be exposed to increasing doses of BWC0977.

Eligibility Inclusion Criteria: Each subject must meet all of the following criteria to be eligible for study participation: 1. Healthy male or female 18 to 55 years of age, inclusive, at time of consent. 2. Body mass index (BMI) = 19.0 and = 30.0 (kg/m2) and weight between 55.0 and 100.0 kg (inclusive). 3. Medically healthy without clinically significant abnormalities at the screening visit or Day -1, including: 1. No findings in Physical examination or vital signs (including temperature, heart rate, respiratory rate, and blood pressure) that the Principal Investigator (PI) determines would interfere with interpretation of study results. 2. Electrocardiograms (ECGs) without clinically significant abnormalities, including a QT duration corrected for heart rate by Fridericia's formula (QTcF) interval duration =450 msec (for males), and =470 msec (for females) obtained as an average from the triplicate screening ECGs after at least 5 minutes in a supine quiet-rest position. 3. Clinically significant abnormalities in the screening clinical laboratory tests, as determined by the Investigator. Repeat testing could be performed at the Investigator's discretion. 4. Willing Exclusion Criteria: Volunteers who meet any of the following criteria will be excluded from the study: 1. Women who are pregnant and/or nursing. 2. History or presence of significant cardiovascular (including QT prolongation, clinically significant hypokalemia, or other proarrhythmic conditions), pulmonary, hepatic, renal, hematological, gastrointestinal, endocrine (including glucose intolerance, diabetes mellitus), immunologic (including asthma or seasonal allergies [that require intermittent use of steroids or other medication]), musculoskeletal (including tendinopathy), dermatologic, or neurological disease (including seizure disorders, psychiatric disorders), including any acute illness or surgery within the past 3 months determined by the PI to be clinically relevant. 3. A serum creatinine value on Day -1 (check-in) that increased by more than 0.2 mg/dL (or 15.25 µmol/L) from the Screening value. 4. History of photosensitivity to quinolones. 5. History of known or suspected Clostridium difficile infection. 6. Any condition that necessitated hospitalisation within the 3 months prior to Day -1 or is likely to require so during the study. 7. Positive test for hepatitis B virus surface antigen (HBsAg), hepatitis C virus antibody (anti-HCV antibodies), or human immunodeficiency virus antibody (antibodies to HIV-1, HIV-2) or tuberculosis (TB) at screening. 8. Exposure to any prescription medications (small molecules, biologics including vaccines) or, systemically administered OTC drugs, dietary supplements or herbal remedies, within 30 days or 5 half-lives (if known), whichever is longer, prior to Day -1. Discussion between the PI and the Sponsor Medical Monitor is encouraged regarding prior use of any medications during the pre-dose period. Note: An exception is made for hormonal contraceptives and a limited amount of paracetamol (a maximum of 4 doses per day of 500-mg paracetamol, and no more than 3 g per week) for the treatment of headache or any other pain. 9. Documented hypersensitivity reaction or anaphylaxis to any medication. 10. Smoker (including tobacco, e-cigarettes or marijuana) or nicotine user within 1 month prior to participation in the study 11. Positive urine drug/alcohol testing at screening or check-in (Day -1), or history of substance abuse or alcohol abuse (defined as greater than 2 standard drinks on average each and every day, where one standard drink is defined as containing 10 g of alcohol and is equivalent to 1 can or stubby of mid-strength beer, 30 ml nip spirits, or 100 ml wine) within the previous 5 years (may be repeated once per timepoint, at the discretion of the PI, in the instance of a positive result). 12. Donation of blood or plasma within 30 days prior to randomization, or loss of whole blood of more than 500 mL within 30 days prior to randomization, or receipt of a blood transfusion within 1 year of study enrollment. 13. Previous participation in this study or previous participation in another study within 5 half-lives (if known) of the agent, whichever is longer, of Day 1. Note: prior participation at any time in non-invasive methodology trials in which no drugs were given is acceptable. 14. Consumption of red wine, seville oranges, grapefruit or grapefruit juice, pummelos, other citrus fruits, grapefruit hybrids or fruit juices containing such products from 7 days prior to the first dose of study medication. 15. Employee or family member of an employee of the Sponsor, CRU, or clinical research organization at which the study will be conducted. 16. Unable to cooperate fully with the requirements of the study protocol, including the schedule of assessments, or likely to be non-compliant with any study requirements. 17. Any disease or condition (medical or surgical) that, by the determination of the PI, precludes the subject's participation in the study or would place the subject at risk as a result of participation in the study. Note: Volunteers should refrain from consumption of any foods containing poppy seeds within 48 hours (2 days) prior to screening and prior to Day -1 to avoid false positive drug screen results

Study Design


Intervention

Drug:
BWC0977
SAD Cohorts: Double-blind dosing will occur. Six participants will receive single doses of BWC0977. The dose escalation steps may be altered following review of the safety data upon completion of each cohort. MAD Cohorts: Double blind dosing will occur. Six participants in each cohort will receive multiple doses of BWC0977. The dose escalation steps may be altered following review of the safety data upon completion of each cohort. Dosing will commence on the morning of Day 1. Dosing frequency to be confirmed based on safety, tolerability and PK data from SAD cohorts. Daily dosing will continue for a total of 10 consecutive days.
Placebo
SAD Cohorts: Two participants in each cohort will receive matching placebo. MAD Cohorts: Two participants in each cohort will receive matching placebo.
