• 2 other identifiers: 05-0121SPL7013-004
• Study Type: interventional
• Target: 56
• Locations: 2 countries
• Sites: 2

Brief Summary

The purpose of this study is to test the safety and tolerability of a medication applied vaginally twice daily in females versus placebo (inactive substance). Study participants will include 60 women, ages 18-24, non-pregnant, previously sexually active, Human Immunodeficiency Virus (HIV) negative and sexually transmitted infection (STI) free, in San Francisco or Kisuma, Kenya. Each study participant will be followed for 14 days of product use and an additional 7 days for safety assessments. Study procedures will include a physical exam with a pap smear, urine testing, blood sample testing, and a colposcopy (exam of the vagina and cervix using a lighted magnifying instrument). Information learned from this study may help to develop a safe and effective medication that could prevent herpes simplex virus and HIV. Participants may be involved in study related procedures for up to 55 days.

Conditions

Outcome Measures

Primary Outcomes (2)

• Tolerability will assess the degree to which overt Adverse Events can be tolerated by the study participants.

  Tolerability measures will be assessed at Days 2, 7, and 14 visits.

• Safety will be assessed by laboratory tests and clinical Adverse Events.

  Safety assessed after 2, 7, and 14 days of product use and 7 days following the completion of product use (Day 21).

Secondary Outcomes (4)

• Presence and expression levels of Human Immunodeficiency Virus co-receptors CCR5 and CXCR4, and their principal chemokine ligands by endocervical immune cells.

  Immunologic factors of the genital tract will be measured using cervicovaginal specimens collected at enrollment, Day 7, Day 14, and Day 21.

• Secretory Leukocyte Protease Inhibitor levels.

  Immunologic factors of the genital tract will be measured using cervicovaginal specimens collected at enrollment, Day 7, Day 14, and Day 21.

• Number and activation levels of endocervical immune cell populations.

  Immunologic factors of the genital tract will be measured using cervicovaginal specimens collected at enrollment, Day 7, Day 14, and Day 21.

• Innate mucosal defenses, including local levels of cytokines in cervical secretions, and Toll-Like Receptor expression by cervical immune cells.

  Immunologic factors of the genital tract will be measured using cervicovaginal specimens collected at enrollment, Day 7, Day 14, and Day 21.

• Age Groups: Adult (18-64)

You may qualify if:

• Subject has voluntarily given written informed consent to participate in the study.
• Subject is female and aged between 18 and 24 years, inclusive.
• Subject is sexually active.
• Subject should have a menstrual cycle length of at least 25 days.
• Subject is in good health, as determined by medical history, a baseline physical examination, and clinical laboratory tests.
• Subject agrees to comply with all study procedures.
• Subject has no significant abnormal vaginal microflora (abnormal flora defined as Nugent score greater than or equal to 7) at screening.
• Subject has a negative urine pregnancy test at screening and enrollment.
• Participant must agree to abstain from all sexual activities involving intercourse or other forms of vaginal penetration 7 days prior to the Enrollment Visit through the completion of all follow-up visits and procedures.

You may not qualify if:

• Subject has received or is anticipated to receive a new prescription systemic or topical medication within 14 days prior to the start of dosing. Subjects may be enrolled if stable on existing therapy as determined by the Principal Investigator.
• Subject has received any new long-acting treatments \[e.g. depot formulation including medroxyprogesterone acetate (DMPA) form of hormonal birth control\]. Subjects may be enrolled if stable (greater than 3 months) on existing therapy as determined by the Principal Investigator.
• Subject has received an investigational drug within 30 days or 10 half-lives of the drug, whichever is longer, prior to entering this study, or is planning to receive another investigational drug while participating in this study.
• Subject has a history of significant drug allergy.
• Subject has a history of latex allergy.
• Biological and hematological parameters are outside of the laboratory's normal reference ranges. Subjects with grade 1 laboratory abnormalities can be included if the Principal Investigator judges that the deviations are not clinically relevant.
• Subject has a clinically significant history of systemic allergic disease (e.g., clinically significant urticaria, clinically significant atopic dermatitis).
• Subject has a history of recurrent vaginal infections, irritation or localized reaction to vaginally applied agents.
• Subject has an unpredictable or irregular menstrual cycle that will not allow scheduling of the colposcopic examinations outside menstruation as required for the protocol.
• Subject has a recent (within 3 months) history of intermenstrual bleeding.
• Subject has an active, uncontrolled medical condition (e.g., neurological, gastrointestinal, renal, hepatic, cardiovascular, pulmonary, metabolic, endocrine, hematological, genitourinary or other major disorder), or psychiatric illness (e.g., depression, schizophrenia).
• Subject had a clinically significant illness within 30 days prior to screening.
• Subject has used a vaginal preparation within 30 days prior to screening.
• Subject has a clinically detectable genital abnormality (i.e. vulvar, vaginal, cervical, perianal ulcer and/or deep epithelial disruption).
• Subject has signs, as seen on pelvic exam, consistent with an Sexually Transmitted Infection (STI), other genital tract infection - other than bacterial vaginosis (BV) - or trauma, including but not limited to: vaginitis, cervicitis, and laboratory findings indicative of genital tract infection other than asymptomatic BV.
