Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 40 years
  • Women only
  • Healthy volunteers accepted
  • Adult

Who may be able to join

  • Healthy female subjects aged 18 - 40 years.
  • Body mass index (BMI) ≥18 and ≤30 kg/m2.
  • Subjects weight ≥50kg and ≤100kg at screening.
  • Able to voluntarily provide written informed consent to participate in the study.
  • Subjects are pre-menopausal.
  • Females of childbearing potential must have a negative pregnancy test at screening (β HCG) and prior to each dose.

  • Established use of oral, injected or implanted hormonal methods of contraception.
  • Placement of an intrauterine device (IUD) or intrauterine system (IUS).
  • Barrier methods of contraception: Condom or occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/suppository.
  • Male sterilisation (with the appropriate post-vasectomy documentation of the absence of sperm in the ejaculate). [For female subjects, the vasectomised male partner should be the sole partner for that subject].
  • True abstinence, when this is in line with the preferred and usual lifestyle of the subject.
  • [Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception].
  • The chosen contraception method(s) must be followed from the first dose until at least Day 85 of the study.
  • Non-smokers for at least 3 months prior to first study vaccine administration.

Who cannot join

  • Subjects who have received GBS-NN vaccine previously.
  • Subjects with history or presence of significant cardiovascular disease, pulmonary, hepatic, gallbladder or biliary tract, renal, haematological, gastrointestinal, endocrine, immunologic, dermatological, neurological, psychiatric, autoimmune disease or current infection.
  • Pregnant or lactating females.
  • Laboratory values at screening which are deemed by the investigator to be clinically significantly abnormal.
  • Positive drug screen for drugs of abuse or a positive alcohol urine test prior to first dosing unless there is a documented medical explanation for the positive result other than drugs of abuse (e.g., the subject has been prescribed opioids for pain).
  • Positive for human immunodeficiency virus (HIV), hepatitis B or hepatitis C.
Show all 14Show fewer
  • Participation in a clinical drug study during the 90 days preceding the initial dose in this study.
  • Any significant illness during the 4 weeks preceding check-in for this study (Day 1).
  • Subjects with a history of allergic reactions after previous vaccination.
  • Subjects who have received any vaccine within 30 days of screening, or who are planning to receive a vaccine up to Day 85 of the study.
  • Subjects receiving immunosuppressive therapy in the 6 months prior to screening, taking any short-term medications including over-the-counter (OTC) preparations, within 7 days of the first dose. Chronic medications such as antihypertensives, bronchodilators, oral contraceptives or statins that do not affect the immune system, will be permitted and allowed to continue during the study at the discretion of the Investigator. Paracetamol will be permitted for the treatment of headache or other symptoms. Use of OTC vitamins and dietary supplements is allowed
  • Subjects with tattoos at the proposed site of vaccine administration.
  • Donation of blood or blood products within 90 days prior to vaccine administration or intending to donate blood or blood products within 90 days of the last visit.

About this study

Official title: A Phase I, Randomised, Double-blind, Placebo-controlled, Parallel Group Study to Evaluate the Safety, Tolerability and Immunogenicity of Two Doses of Group B Streptococcus Vaccine (GBS-NN/NN2 With Alhydrogel®) in Healthy Female Subjects Aged 18 to 40

A Phase I, randomised, single centre, double-blind, placebo-controlled, parallel group study to evaluate the safety, tolerability and immunogenicity of two doses of Group B Streptococcus vaccine.

Read the detailed description

There will be 4 arms in 2 cohorts of 30 subjects. Cohort 1 will receive two 0.5 mL injections, 4 weeks apart, each consisting of 25 μg of GBS-NN and 25 μg of GBS-NN2 (24 subjects) or placebo (6 subjects). Cohort 2 (30 subjects) will receive two 0.5 mL injections, 4 weeks apart, each consisting of 50 μg of GBS-NN and 50 μg of GBS-NN2 (24 subjects) or placebo (6 Subjects). All vaccines will be adsorbed to 500 μg Al3+ as Alhydrogel®.

Safety will be assessed after all subjects have completed Visit 4 (Day 8) for Cohort 1, at which point the decision will be made as to whether proceeding with administration of the doses in cohort 2 is appropriate.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing GBS-NN/NN2 with Alhydrogel® 25 and GBS-NN/NN2 with Alhydrogel® 50 in people with Group B Strep Infection, run by Minervax ApS at 1 site in United Kingdom.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 14 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 2 Feb 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 24 Dec 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Participants With Treatment Emergent Adverse Events (time frame: 85 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Feb 2021.
