Study summary

This randomized, double-blind, placebo-controlled study is a first-in-human Phase 1 study using two dose levels of an investigational vaccine directed against S. aureus and Candida. The study is designed to evaluate the safety, tolerability and immunogenicity of the investigational vaccine, NDV-3

Read the 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. This Phase I study will evaluate the safety and immunogenicity of a two doses administered 6 months apart of NDV-3 vaccine at two dose levels. At least 40 subjects will be enrolled in the study in two groups of approximately 20 subjects each. Each group will be randomized so that 15 will receive NDV-3 vaccine and 5 will receive placebo. All injections will be administered intramuscularly. One group will receive a low dose of NDV-3 and the other a ten-fold higher dose. Subjects will have follow-up visits to assess the safety, tolerability and immune responses at days 3, 7, 14, 28, 90 and 180 after the first vaccination to compare to baseline levels and at days 7, 14 and 90 after the second vaccination.

  5. Female subjects must be:

    • of and practicing an acceptable method of described below as judged by the investigator(s); or
    • of status (no menses) for at least 1 year and has a documented FSH level ≥ 40 mIU/mL; or
    • sterile (surgically [bilateral tubal ligation, bilateral oophorectomy, or hysterectomy] or the Essure® Procedure).

Exclusion criteria

Exclusion Criteria:

Terms in these criteria, in plain language(13)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

ECG (electrocardiogram)

A recording of the heart’s electrical activity, taken with stickers on the chest, arms and legs. It takes a few minutes and does not hurt.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Postmenopausal

Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Live vaccines

Vaccines made with a weakened form of the germ, such as measles–mumps–rubella (MMR), chickenpox and yellow fever. They can be risky when the immune system is weakened. Flu injections are not live; the nasal flu spray is.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 22, 2012, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
