Current Primary Outcome Measures  ICMJE
 (submitted: January 17, 2014)
Safety and tolerability of TKM-100802 [ Time Frame: 1 month ]
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.

Brief Title  ICMJE Safety, Tolerability and Pharmacokinetic First in Human (FIH) Study for Intravenous (IV) TKM-100802
Official Title  ICMJE A Placebo-Controlled, Single-Blind, Single-Ascending Dose Study With An Additional Multiple-Dose Cohort to Evaluate the Safety, Tolerability, and Pharmacokinetics of TKM-100802 in Healthy Human Volunteers
Brief Summary Phase 1, single-center, placebo-controlled, single-blind, first-in-human, single ascending dose (SAD) study followed by a multiple-dose cohort in healthy male and female subjects.
Detailed Description Approximately 20 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 multiple-dose phase, one cohort is planned with 4 subjects (3 receiving TKM-100802 and 1 receiving saline) at a maximum dose of 0.24 mg/kg TKM-100802.

Eligibility Criteria  ICMJE

Inclusion Criteria:

  1. Informed of the nature of the study and are able to read, review, agree to, and sign the informed consent document at Screening.
  2. Able to comply with all protocol-specified visit schedules and requirements.
  3. Healthy male and female subjects 18 to 50 years of age, inclusive, at the time of dosing.
  4. Body mass index (BMI) between 22 kg/m2 to 35 kg/m2, inclusive, and weigh at least 110 lbs (50 kg).

4a. Systolic blood pressure ≥110 mmHg (subject in the seated position and legs dangling) also, 5 minutes after moving from the supine to seated position any drop in systolic pressure must be <15 mmHg and any increase in pulse <10 bpm.

5. 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.

6. 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.

7. 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. 8. 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:

  1. 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.
  2. Reports an uncontrolled psychiatric disorder or neurologic disease or seizure disorder not controlled by medication.

  16. Reports infections requiring antibiotic therapy within 28 days of Screening (as determined by the PI).

  21. Demonstrates a positive drug or alcohol screen.
  22. Reports a history of drug or alcohol addiction or abuse within the past 1 year.
