A Two Part Randomized, Open-Label Phase I Safety and Pharmacokinetic Evaluation of Gel and Ovule Formulations of TOL-463 (Intravaginal Therapy) in 18-45 Year Old Healthy Female Subjects and Women With Vaginitis

Date de début de l'étude : 1 avril 2013

Inclusion Criteria: Adult women of any race between 18 to 45 years of age (inclusive). Subjects must be able to give voluntary written informed consent before any study related procedure is performed. Subjects must have a negative serum pregnancy test at Screening and negative urine pregnancy test at all other clinical site visits, as applicable. Subjects either have no childbearing potential (as defined below) (Note 1) or agree to avoid becoming pregnant from the day of screening through one month after the last study Day using one of the following acceptable methods of birth control (Note 2) in addition to the use of non-lubricated condoms by the male partner (even if vasectomized). Hormonal contraceptives Abstinence Note 1: Non-childbearing potential is defined as being post-menopausal for at least 2 years, status after bilateral tubal ligation for at least 1 year, status after bilateral oophorectomy or status after hysterectomy. Note 2: Intravaginal or intra-uterine contraceptives and contraceptive devices (IUDs) are not acceptable forms of birth control for this study. Subjects must agree to refrain from douching or using any intravaginal products (i.e., contraceptive creams, gels, foams, sponges, lubricants, etc.) or IUDs during the study period. Subjects must agree not to donate blood during the study and up to 14 days after the end of the study. Subjects willing and able to comply with all study requirements. For Part 1 Only Subjects must be healthy as determined by medical history, physical examination, vital signs, pelvic examination and laboratory evaluations (hematology, clinical chemistry and urinalysis tests) within study-defined ranges at Screening. Subjects must be without current symptomatic or asymptomatic bacterial vaginosis, candida vulvovaginitis or any other form of vaginitis by clinical and microbiologic testing. Subjects must be willing to abstain from sexual intercourse for 24 hours prior to each site visit. For Part 2 Only Subjects with vaginitis must be otherwise healthy based on medical history, physical examination, vital signs, pelvic examination and laboratory evaluations (hematology, clinical chemistry and urinalysis tests) within study-defined ranges at Screening. Subjects with vaginitis must be willing to abstain from sexual intercourse 24 hours prior to the first dose of study medication and throughout the last visit of the study. Exclusion Criteria: A history of clinically significant acute illness (resolved within 4 weeks of screening) or any other condition which, in the opinion of the Site Principal Investigator (PI), would jeopardize the safety of the subject or impact the validity of the study results. Subjects with intrauterine devices. Subjects with renal dysfunction (serum creatinine >/= 1.2 mg/dL). Subjects with underlying metabolic or endocrine dysfunction, such as diabetes mellitus, Cushing's disease, Addison's disease, or hypo- or hyperthyroidism. Subjects who test positive for HIV, hepatitis B surface antigen (HBsAg), or hepatitis C antibody. Subjects who have diseases known to cause immunodeficiency, e.g., AIDS, advanced malignancy, anemia or severe vitamin deficiency. Subjects who test positive for Trichomonas vaginalis, Neisseria gonorrhea, or Chlamydia trachomatis at screening. Subjects with active genital lesions at screening, including syphilitic chancre, herpetic lesions, or genital warts (HPV). Subjects who have had major surgery within 4 weeks of screening. Subjects with an uncontrolled active illness (e.g., active infection) or fever (oral temperature >/=100 degrees F or >/= 37.7 degrees C) at screening. Subjects with a known sensitivity to any ingredient in TOL-463 vaginal gel or ovule. With the exception of oral contraceptives, use of a prescription medication, notably antimicrobial agents, corticosteroids or other immuno-suppressants, within 14 days prior to Day 1 of study treatment, unless in the opinion of the PI, the substance would not likely impact the conduct or results of this study. Subjects with any current unstable medical condition(s) requiring prescription medication(s) that would preclude accurate evaluation of subjects or otherwise impact the conduct or results of the study. Subjects who have received an investigational drug in a clinical trial within 30 days prior to screening. Women who are pregnant or breast feeding. Subject has a positive history for alcohol abuse or dependence and/or a positive urine screen test for alcohol and drugs of abuse [amphetamines, barbiturates, benzodiazepines, cocaine metabolites, marijuana, opiates, phencyclidine (PCP)] at screening or at any check-in prior to receiving study drug. Subjects who have donated blood within the past 30 days prior to Day 1 of treatment with study drugs.
