Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE1
• Total Enrollment: 48 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2024-05-09
• Study Completion Date: 2025-07-04

Brief Summary

The goal of this clinical trial is to learn if the oral biologic MB-001 is safe in healthy volunteers. The main questions it aims to answer are:

Is the drug safe when administered orally at increasing doses? Researchers will compare the drug with placebo to see if there are more side effects in those receiving the drug.

Participants will receive a single or five daily doses of the drug or placebo and will be asked to stay in the clinic for five days following the last dose.

Detailed Description

This is a two-stage, single-center, double-blinded, randomized, placebo-controlled study evaluating the safety ofMB-001 in healthy adult participants.

The two stages are:

• A single ascending dose (SAD) stage in healthy participants.
• A multiple ascending dose (MAD) stage in healthy participants.

Up to 5 cohorts of healthy adult participants will receive a single oral dose of either MB-001 or placebo. Following a review of all safety data available for the current cohort and any preceding cohorts, the Safety Review Committee (SRC) will decide whether to proceed to the next cohort. The MAD stage in healthy participants will commence once sufficient safety data are available from the SAD stage, after the completion of all SAD cohorts.

6. Agrees not to donate sperm or ova from first dose of study drug until 90 days or 30 days, respectively, after the last dose of study drug.

7. Willing and able to comply with the study requirements, including remaining at the CRU for the in-house portion of study participation.

8. Agrees not to smoke, vape, or consume tobacco or other nicotine-containing products, from screening until the end of study participation. This includes the use of nicotine patches.

9. Agrees not to consume alcohol from 3 days prior to first dose of study drug until the end of the in-house portion of study participation.

10. Agrees not to consume products containing caffeine or other xanthines from 2 days prior to first dose of study drug until the end of the in-house portion of study participation.

11. Is in good health based on medical history, physical examination, vital signs measurements, safety laboratory tests, and electrocardiograms (ECGs) performed at screening.

Exclusion Criteria

1. Has any condition that places the participant at significantly increased risk or may compromise the study objectives.

2. Is mentally or legally incapacitated, at screening or expected during the conduct of the study or has a history of a clinically significant psychiatric disorder that would impact study conduct.

3. Has a history of lymphoma, leukemia, or any malignant neoplasms or carcinoma in situ within 5 years prior to screening (except successfully treated nonmetastatic cutaneous squamous cell or basal cell carcinoma and/or localized carcinoma in situ of the cervix).

4. Regularly consumes more than 2 units of alcoholic beverages per day or more than 14 units per week (1 unit of alcohol equals 1 pint [473 mL] of beer or lager, 1 glass [125 mL] of wine, 25 mL shot of 40% spirit) within 1 month prior to screening.

5. Has a history of drug or alcohol abuse (defined by the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition) within 3 months prior to screening.

6. Females who are pregnant or lactating.

7. For participants of childbearing potential, has a positive pregnancy test at screening or Day -1.

8. Has a QTc > 450 msec for male participants or > 470 msec for female participants at screening or Day -1. NOTE: The QTc is the QT interval corrected for heart rate according to Fridericia's formula (QTcF = QT/(RR^0.33).

9. Has any 12-lead ECG finding at screening or prior to first dose of study drug that may, in the opinion of the Investigator, compromise interpretation of ECGs for cardiac safety assessment or complicate interpretation of events that may occur post dose (e.g., QT not accurately measurable, conduction abnormalities).

10. Has alanine transaminase or aspartate transaminase levels > 1.5 x upper limit of normal (ULN) at screening or Day -1.

11. Has total bilirubin > 1.5 x ULN (isolated bilirubin > 1.5 x ULN is acceptable if total bilirubin is fractionated and direct bilirubin is < 35%) at screening or Day -1.

This includes, but is not limited to, hepatitis virus infections, drug- or alcohol-related liver disease, non-alcoholic steatohepatitis, autoimmune hepatitis, hemochromatosis, Wilson's disease, α-1 antitrypsin deficiency, primary biliary cholangitis, primary sclerosing cholangitis, or any other liver disease considered clinically significant by the Investigator.
