Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
For single ascending dose, five dose target ranges of BT-11 (depending on body weight the doses in each cohort will be 5.9 – 7.7 mg/kg; 18.9 – 25.0 mg/kg; 44.3 – 50.0 mg/kg; 68.5 – 75 mg/kg and 94.2 – 100.0 mg/kg) will be evaluated, based on subject’s weight on Day 1.

For multiple ascending dose (once daily for 7 days), three dose target ranges of BT-11 (depending on body weight the doses in each cohort will be 5.9 – 7.7 mg/kg; 44.3 – 50.0 mg/kg; and 94.2 – 100.0 mg/kg) will be evaluated, based on subject’s weight on Day 1.

White tablets containing 500 mg BT-11 or matching placebo tablets will be dispensed.

Single ascending dose duration of administration will be once. For multiple ascending dose it will be up to 7 days.
The mode administration will be oral tablet.
Compliance and adherence to the intervention will be performed based on the tablet return, tablet not consumed by the subject.

The safety monitoring committee will evaluate safety at conclusion of single ascending cohort 2 prior to the commencement of dosing for the multiple ascending dose.

3. Any 12-lead ECG finding at screening or on Day –1 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)
4. Positive test for HIV, hepatitis B surface antigen, or hepatitis C antibody.
5. Any clinically significant cardiac, pulmonary, renal, metabolic, neurologic, or other medical, behavioural, or genetic condition.

11. Positive urine drug screen (including cotinine, cannabis, cocaine, opiates, amphetamines, and other tests as determined by Investigator). Repeating analyses will be allowed if the PI suspects that there might be false positive results.
12. Volunteer has a contraindication to blood sampling or is considered to have insufficient peripheral venous access.
13. Volunteer has donated blood or blood products in volumes of 450 mL or more within 30 days prior to study enrollment.
14. Volunteer has been previously exposed to BT-11.

Summary
Brief summary
This is a double-blind, placebo controlled, ascending dose, multi-cohort trial. The study will be conducted with a single ascending dose (SAD) phase and a multiple ascending dose (MAD) phase. In SAD, participants will receive one dose of BT-11 or placebo. In MAD, participants will receive multiple doses of BT-11 or placebo for 7 consecutive days. In both parts, sequential cohorts will be exposed to increasing doses of BT-11. In SAD, five doses will be evaluated, in MAD 3 dose levels will be evaluated.
