Study to Assess the Pharmacodynamic Effects of Unfractionated Heparin (UFH) in Healthy Volunteers With and Without Bendavia

Phase 1

Completed

• Conditions: Healthy Volunteers
• Interventions: Drug: Unfractionated heparin (UFH); Drug: Saline (0.9%, sterile, for infusion); Drug: Bendavia

• Registration Number: NCT01513200
• Lead Sponsor: Stealth BioTherapeutics Inc.

Brief Summary

This will be a phase 1 randomized, double-blind crossover trial enrolling approximately 12 healthy volunteers to assess whether intravenous (IV) UFH and IV Bendavia administered together have any significant impact on the pharmacodynamic effects of UFH and the pharmacokinetics of Bendavia.

• Any addition laboratory abnormalities determined as clinically significant by the Principal Investigator at laboratory screening,

• Clinically significant abnormalities on physical examination,

• Body Mass Index (BMI) of less than 18 kg/m2 or greater than 32 kg/m2,

• Any disease or condition that might compromise the cardiovascular, hematological, renal, hepatic, pulmonary (including chronic asthma), endocrine (e.g., diabetes), central nervous, or gastrointestinal (including an ulcer) systems,

• History of seizures or history of epilepsy,

• History of serious (Principal Investigator judgment) mental illness,

• Receipt of investigational medicinal product within 30 days before planned date of unfractionated heparin and/or study drug administration,

• Positive serology for human immunodeficiency virus 1 or 2 (HIV1 or 2), hepatitis B surface antigen (HBsAg) or hepatitis C virus (HCV),

• Fever greater than 37.5°C at the time of planned dosing,

• Suspicion of or recent history of alcohol or substance abuse,

• Donated blood or blood products within the past 30 days,

• Women who are pregnant or breastfeeding,

• Employee or family member of the investigational site,

• Subjects who currently smoke cigarettes, cigars, pipes or chew tobacco products or who have used any tobacco products in the 30 days prior to screening,

• Subjects who are either unwilling to agree to refrain from using or found to be using:

  1. Alcohol, caffeine, xanthine-containing food or beverages, nicotine products and over-the-counter medications with the exception of Tylenol from 24 hours prior to dosing and throughout the confinement period
  2. Prescription medications from 14 days prior to and 7 days post treatment (excluding hormonal contraceptives)
  3. Hormonal contraceptives without concomitant use of double-barrier contraceptives (condom, diaphragm with spermicide) for a period of 7 days prior to and 30 days post treatment

• Subjects taking aspirin or any other non-steroidal anti-inflammatory agent, either prescription or over-the-counter, within 10 days of treatment,

• Subjects known to have allergic or untoward effects when using unfractionated heparin,

• Subjects having previous exposure to Bendavia,

• Subjects who are expected to undergo any surgical procedure within 14 days of the completion of the study.

Arm && Interventions

Group	Intervention	Description
UFH + Placebo	Saline (0.9%, sterile, for infusion)	UFH (60U/kg bolus followed by 12U/kg/hr for approx.11 hours) with saline (placebo) administered as infusion for the last 4 hours of UFH
UFH + Bendavia	Bendavia	UFH (60U/kg bolus followed by 12U/kg/hr for approx.11 hours) with Bendavia (0.25mg/kg/hr) administered as infusion for the last 4 hours of UFH
UFH + Placebo	Unfractionated heparin (UFH)	UFH (60U/kg bolus followed by 12U/kg/hr for approx.11 hours) with saline (placebo) administered as infusion for the last 4 hours of UFH
UFH + Bendavia	Unfractionated heparin (UFH)	UFH (60U/kg bolus followed by 12U/kg/hr for approx.11 hours) with Bendavia (0.25mg/kg/hr) administered as infusion for the last 4 hours of UFH

Primary Outcome Measures

Name	Time	Method
Mean difference over 24 hours in aPTT (activated partial prothrombin time) in seconds when UFH is administered with and without Bendavia	Pre-UFH to 24 hours post-study drug administration	Difference in group (with/without Bendavia) means of aPPT values will be assessed for statistical significance (Analysis of Variance; ANOVA) at the following time points: Pre-UFH, Pre-Study-Drug infusion start and 1, 2, 3, 4, 5, 6, 8, 12 and 24 hours Post-Study-Drug infusion start.

Secondary Outcome Measures

Name	Time	Method
Mean difference over 12 hours of anti-factor Xa (IU/mL) when UFH is administered with and without Bendavia	Pre-UFH to 12 hours post-study drug administration	Difference in group (with/without Bendavia) means of aPPT values will be assessed for statistical significance (ANOVA) at the following time points: Pre-UFH, Pre-Study-Drug infusion start and 4, 8 and 12 hours Post-Study-Drug infusion start.
Mean difference in Bendavia Area Under the Curve(0-infinity) (AUC) when Bendavia is administered with and without UFH (historical data will be used to provide bendavia without UFH)	48 hours post-study-drug administration
Difference in number of adverse events when UFH is administered with and without Bendavia	Pre-dose through Day 10	Adverse events will be described by treatment group (UFH with and without Bendavia). No statistical analysis of the difference between AEs will be conducted.
