Study summary

The purpose of this research study is to check whether the MNS Miracus Patch (the study's investigational device, a small patch made up of microneedles that dissolve in the skin and can potentially deliver vaccines in a pain-free way) is safe to use and tolerated by humans when administered for 10 minutes, both as a plain patch (with no vaccine) and as a loaded patch (with the tetanus- containing vaccine included). This study will also investigate whether the patch delivers the correct dose of the vaccine in the loaded patches by checking the immune response of participants.

As the device has not been tested clinically in humans before, this will be a first-in-human study involving healthy participants only, who have not previously received the full course of tetanus diphtheria vaccinations. This research study will take approximately 4-6 weeks of the participants' time.

The study consists of a screening period up to 2 weeks to determine if participants are eligible for the study. Upon confirmation of eligibility, participants will enter the 'double-blind' study where they will receive one patch in clinic.

Double-blind means that neither the participant nor the study doctor will know if the individual is receiving the empty or loaded patch. Participants will be randomly selected to receive the empty or loaded patch, and the number of participants will be equal in each group.

During the study, participants will be asked to complete questionnaires, have photographs taken of their skin, give blood and urine samples and undergo general health checks including physical exam and vital signs.

The clinical trial is funded by Microneedle Solutions Ltd. And Innovate UK, and will recruit 30 participants at one site in the UK only.

Willing to comply with all study procedures and attend all scheduled visits.

Exclusion criteria

Exclusion Criteria:

  • Known allergy or to Tetanus containing vaccine or any skin-contacting components of the Miracus™ patches (polyvinylpyrrolidone (PVP), Polycarbonate (PC), acrylic and/or silicone).
  • Prior Tetanus Containing Vaccine booster within the last 12 months. .
  • Participation in another IMP clinical trial within the last 30 days.

Other hospital or institutional staff not involved in the study may participate, provided there is no direct supervisory or dependent relationship with study personnel.
Terms in these criteria, in plain language(9)

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.

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.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

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.

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).

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.

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.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

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 Jun 3, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
