Primary Outcome Measures:
Safety and tolerability of TKM-100802 [ Time Frame: 1 month ] [ Designated as safety issue: Yes ]
Subjects will be monitored for treatment-emergent and dose-limiting toxicity (DLT). If there are any adverse events (changes from baseline in laboratory parameters, vitals and/or infusion reactions) during these monitoring periods, the Independent Safety Committee, will discuss the dosing of the remaining subjects. Before proceeding to the next dose cohort, the Independent Safety Committee will evaluate whether dose escalation will be permitted based on demonstration of adequate safety and tolerability.
Secondary Outcome Measures:
Pharmacokinetics - Cmax, Tmax and AUC [ Time Frame: 1 month ] [ Designated as safety issue: No ]
Time-points: Before infusion, mid-point of infusion, end of infusion and at 0.25, 0.5, 0.75, 1, 2, 3, 4, 6, 8, 12, 16, 24, 36 and 48 hours after end of infusion and day 7, day 10, day 15, day 22 and day 29.
Estimated Enrollment: 28
Study Start Date: January 2014
Estimated Study Completion Date: July 2014
Estimated Primary Completion Date: July 2014 (Final data collection date for primary outcome measure)

Other Name: Normal saline
Detailed Description:
Approximately 28 male and female healthy adult subjects, 18 to 50 years of age at the time of dosing, will participate in this study. The SAD phase of the study is planned to have up to 4 cohorts with 4 subjects (3 receiving TKM-100802 and 1 receiving saline) in each cohort. Additional cohorts may be enrolled in the SAD phase if a MTD is not established after the initial 4 cohorts. In the MAD phase, a dose escalation scheme will be proposed following review of the findings from cohorts 1 to 4 of the SAD phase. The MAD phase is expected to have at least 3 cohorts with 4 subjects (3 receiving TKM-100802 and 1 receiving saline) in each cohort.
Eligibility
Ages Eligible for Study: 18 Years to 50 Years
Genders Eligible for Study: Both
Accepts Healthy Volunteers: Yes
Criteria
Inclusion Criteria:
Informed of the nature of the study and are able to read, review, agree to, and sign the informed consent document at Screening.
Able to comply with all protocol-specified visit schedules and requirements.
Healthy male and female subjects 18 to 50 years of age, inclusive, at the time of dosing.
Body mass index (BMI) between 22 kg/m2 to 35 kg/m2, inclusive, and weigh at least 110 lbs (50 kg).
Judged by the PI to be in good health as documented by the medical history, physical examination (including but may not be limited to an evaluation of the cardiovascular, gastrointestinal, respiratory and central nervous systems), vital sign assessments, 12-lead ECG, clinical laboratory assessments, and by general observations. Any abnormalities or deviations outside the normal ranges for any of clinical testing (laboratory tests, ECG, vital signs) can be repeated at the discretion of the PI and if judged not to be clinically significant, the subject may be considered for study participation.
Adequate hepatic, renal, hematologic and clotting function as defined by total bilirubin, AST, ALT, serum creatinine, D-dimer and International normalized ratio (INR) within normal range as determined by the PI and Sponsor Medical Monitor.
Female subjects must be one of the following:
naturally postmenopausal (no menses) for >2 years and has a documented FSH level >40 mIU/mL; or
have a documented history of ovarian failure; or
surgically postmenopausal (bilateral oophorectomy or hysterectomy). Female subjects that are surgically postmenopausal must provide documentation of the bilateral oophorectomy or hysterectomy prior to Day 1 dosing to be eligible for participation in the study; or
Women of childbearing potential (FSH ≤40 mIU/mL) must have negative serum hCG at Screening, a negative urine pregnancy test prior to the first study treatment, and must agree to utilize highly effective contraception methods (2 separate forms of contraception, 1 of which must be an effective barrier method, or be non-heterosexually active, or have a vasectomized partner) from Screening throughout the duration of study treatment and for 1 month after the last administration of study treatment.
Male subjects who are sexually active must be willing to use effective barrier contraception (e.g., condom with spermicide) during heterosexual intercourse from Screening throughout the duration of study treatment and for 1 month after the last dose of study treatment.
Exclusion Criteria:
Evidence or history of clinically significant hematologic, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurologic or allergic disease at Screening or medication for comorbidity which according to the PI and Sponsor Medical Monitor preclude subject participation in the clinical study.
Reports an uncontrolled psychiatric disorder or neurologic disease or seizure disorder not controlled by medication.
Subject has a history of, or existing clinically significant cardiovascular disease (for example, uncontrolled hypertension, unstable angina, congestive heart failure or serious cardiac arrhythmias). In addition New York Heart Association Functional Classification Class II or greater will be excluded.
Reports history of coronary heart disease (CHD), CHD-equivalent disease or CHD risk >20% as designated by the National Cholesterol Education Program Adult Treatment Panel III.
Current diagnosis or known history of liver disease (e.g., acute or chronic hepatitis or liver cirrhosis).
History of allergy to cosyntropin (MAD cohort only).
Presence of any clinically significant results from laboratory tests, vital signs assessments and ECGs as judged by the PI.
Reports receiving investigational drugs, biologics, or devices, or any antiviral drugs within 28 days prior to study treatment or planned use during the course of the study.
Reports receiving naturopathic medications, herbal supplements, or lipid lowering therapies within 28 days prior to study treatment or planned use during the course of the study.
A medical condition requiring a prescription treatment which it would be unsafe to discontinue.
Recent treatment with alternative therapies which, in the view of the PI or the Sponsor Medical Monitor, could potentially confound clinical and laboratory assessments.
Demonstrates a marked baseline prolongation of QT/QTc interval (e.g., repeated demonstration of a QTc interval >450 ms).
Reports concomitant use of any medication that prolongs the QT/QTc interval.
Reports a history of additional risk factors for torsades de pointes (e.g., heart failure, hypokalemia, family history of Long QT Syndrome).
When confirmed upon additional testing, demonstrates a reactive screen for hepatitis B surface antigen, hepatitis C antibody, or HIV antibody.
Reports infections requiring antibiotic therapy within 28 days of Screening (as determined by the PI).
Reports a history of Ebola virus exposure.
Reports an occupational health risk of exposure to Ebola virus known to be higher than that of the general population.
Reports a known or suspected hypersensitivity or previous severe reactions to any of the constituents of the TKM-100802 including oligonucleotide- or lipid-based products, liposomal drug products, and phospholipid-based products (parenteral nutrition, Intralipid).
Reports a history of clinically significant allergies including food or drug allergies.
Demonstrates a positive drug or alcohol screen.
Reports a history of drug or alcohol addiction or abuse within the past 1 year.
