  2. Completed the screening process (as described in this protocol) within 28 days prior to dosing.
  3. Healthy male and female volunteers 18-50 years of age, inclusive, at the time of dosing.
  4. No clinically significant deviation from normal as judged by the investigator(s) in 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 electrocardiogram (ECG), clinical laboratory assessments, and by general observations.
  5. Female volunteers must be one of the following:

    • of childbearing potential and practicing an acceptable method of birth control as judged by the Investigator(s)

  15. Reports donating plasma (e.g. plasmapheresis) within 14 days prior to dosing. All subjects will be advised not to donate plasma for four weeks after completing the study.
  16. Demonstrates, in the opinion of study staff, veins unsuitable for repeated venipuncture (e.g. veins difficult to locate, access, or puncture; veins with a tendency to rupture during or after puncture).
  17. Pregnant, lactating, breastfeeding, or intends to become pregnant over the course of the study.
  18. Demonstrates a positive pregnancy screen.

Outcomes

Primary Outcome Measures

Number of Participants With Treatment Emergent Adverse Events
The primary objective of this study is to assess the safety of a single dose of NDV-3 vaccine, administered either IM with or without alum adjuvant at one dose level or ID at a lower dose level, compared to placebo. Clinical evaluations will be assessed on each subject at selected time points up to 90 days post-vaccination.

Secondary Outcome Measures

Immunogenicity - Serum Anti-Als3 IgG
A secondary objective is to compare the serum IgG immune response between the 2 dose levels, routes of administration, and effects of alum adjuvant, at selected time points up to 90 days post-vaccination. Serum IgG will be evaluated by ELISA on serial-diluted samples, resulting in titer values of reciprocal dilution at which the ELISA readout is three times greater than the assay background value.
Immunogenicity - Serum Anti-Als3 IgA1
A secondary objective is to compare the serum IgA1 immune response between the 2 dose levels, routes of administration, and effects of alum adjuvant, at selected time points up to 90 days post-vaccination. Serum IgA1 will be evaluated by ELISA on serial-diluted samples, resulting in titer values of reciprocal dilution at which the ELISA readout is three times greater than the assay background value.
Immunogenicity - Cervicovaginal Wash Anti-Als3 IgG
A secondary objective is to compare the cervicovaginal wash IgG immune response between the 2 dose levels, routes of administration, and effects of alum adjuvant, at selected time points up to 90 days post-vaccination. Cervicovaginal wash IgG will be evaluated by ELISA on serial-diluted samples, resulting in titer values of reciprocal dilution at which the ELISA readout is three times greater than the assay background value.
Immunogenicity - Cervicovaginal Wash Anti-Als3 IgA1
A secondary objective is to compare the cervicovaginal wash IgA1 immune response between the 2 dose levels, routes of administration, and effects of alum adjuvant, at selected time points up to 90 days post-vaccination. Cervicovaginal wash IgA1 will be evaluated by ELISA on serial-diluted samples, resulting in titer values of reciprocal dilution at which the ELISA readout is three times greater than the assay background value.
Immunogenicity - Number of Participants Positive for Peripheral Blood Mononuclear Cells (PBMCs) Producing Als3-specific Interferon-gamma (IFN-g)
A secondary objective is to compare the cellular immune response for Als3-specific production of IFN-g from PBMCs between the 2 dose levels, routes of administration, and effects of alum adjuvant, at selected time points up to 90 days post-vaccination. The IFN-g cellular immune responses will be evaluated by ELISpot using approximately 200,000 PBMCs per well. A positive response was defined as a sample with greater than 20 spot forming units per 10^6 PBMCs.
Immunogenicity - Number of Participants Positive for Peripheral Blood Mononuclear Cells (PBMCs) Producing Als3-specific Interleukin-17A (IL-17A)
A secondary objective is to compare the cellular immune response for Als3-specific production of IL-17A from PBMCs between the 2 dose levels, routes of administration, and effects of alum adjuvant, at selected time points up to 90 days post-vaccination. The IL-17A cellular immune responses will be evaluated by ELISpot using approximately 200,000 PBMCs per well. A positive response was defined as a sample with greater than 20 spot forming units per 10^6 PBMCs.

5. Study Description

Brief Summary
This partially-blind, placebo controlled study is a Phase 1b study using an investigational vaccine, NDV-3, directed against Staphylococcus aureus and Candida sp. This study will compare NDV-3 administered with or without alum delivered intramuscularly (IM) at one dose level. It will also evaluate a lower dose of NDV-3 without alum delivered intradermally (ID) compared to placebo delivered ID.
Detailed Description
Preclinical studies in mice have established that several members of the Als family of proteins induce a protective immune response in mice and allow high survival rates following challenge with highly virulent doses of either Candida or S. aureus. Als3 (the antigen in the NDV-3 investigational vaccine) is the most effective member of the Als protein family in protecting mice from challenge with either Candida or S. aureus. The first Phase 1 study enrolled 40 healthy subjects that received placebo (N=10), 1 dose (N=30) or 2 doses (N=19) of the NDV-3 vaccine administered intramuscularly (IM). The vaccine was well tolerated and highly immunogenic. This study will evaluate the safety, tolerability and immunogenicity of one dose of NDV-3 vaccine formulated with and without alum given IM and also a lower dose without alum given intradermally (ID). Subjects will have follow-up visits to assess the safety tolerability and immune responses at selected time points up to 90 days post-vaccination.
