LVT-001

Clinical trials are investigating LVT-001 as an intranasal COVID-19 vaccine booster in healthy adults. These studies aim to assess safety and immune response, and to compare it with an intramuscular mRNA COVID-19 booster. The trial is in Phase 1/2 and includes healthy volunteers.

Trial overview

NCT06821126 is an interventional study of LVT-001 in healthy adults.[1] It is a randomized, controlled, multicenter Phase 1/2 trial with 238 planned participants.[1] The study is authorised.[1]

The trial compares an intranasal booster dose of LVT-001 with a COVID-19 mRNA booster given by injection into the muscle.[1] The main goal is to study safety and the immune response after vaccination.[1]

Who is being studied

The target population is healthy volunteers, meaning adults without the condition being treated in the study.[1] The brief summary says the trial is in healthy adult volunteers.[1]

No other detailed eligibility rules are given in the source data.[1] Based on the available information, the study is focused on people who can safely join a vaccine booster trial and help researchers compare two booster approaches.[1]

What is being tested

The study tests LVT-001 as an intranasal COVID-19 vaccine booster.[1] “Intranasal” means it is given through the nose.[1]

The trial also compares LVT-001 with Comirnaty JN.1, a COVID-19 mRNA vaccine given by intramuscular injection.[1] This comparison helps researchers see whether the nasal booster gives a stronger response in the nose lining, which is called the mucosa.[1]

In Phase 1, the study evaluates three booster doses of LVT-001: 20 µg, 60 µg, and 120 µg.[1] In Phase 2, it compares the immune response after the nasal booster with the response after the injected mRNA booster.[1]

Trial phases and design

This is a Phase 1/2 study, which means it combines early safety testing with a more detailed look at immune response.[1] Phase 1 is mainly about safety, while Phase 2 looks at whether the booster creates a better mucosal immune response.[1]

The study is randomized and controlled.[1] Randomized means participants are assigned to study groups by chance, and controlled means the trial includes a comparison group.[1] It is also multicenter, so it is carried out at more than one study site.[1]

What outcomes are measured

The Phase 1 outcomes focus on safety after vaccination.[1] Researchers measure immediate adverse events within 1.5 hours, solicited local reactogenicity and systemic signs and symptoms over 7 to 14 days, unsolicited adverse events up to 28 days, and serious safety events throughout the trial.[1]

Reactogenicity means the expected short-term reactions after a vaccine, such as local or body-wide symptoms.[1] The study also tracks serious adverse events, serious adverse reactions, suspected unexpected serious adverse reactions, and adverse events of special interest.[1]

The Phase 2 outcome measures the change in mucosal humoral immune response from day 0 to day 28.[1] This is measured by ELISA using IgA from nose swabs.[1] IgA is a type of antibody, and nose swabs help show how the immune system responds in the nose lining.[1]

What this trial means for patients

This trial is not about treating people who are already sick with COVID-19.[1] It is about testing a booster vaccine approach in healthy adults and learning whether a nasal booster can produce a useful immune response.[1]

The study may help answer two important questions: first, whether LVT-001 is safe enough to keep studying, and second, whether it may work better than a standard injected booster for immune protection in the nose.[1] Because the trial is still in Phase 1/2, it is an early step in research and is mainly designed to gather safety and immune-response data.[1]

Glossary

  • Phase 1: The first part of a clinical trial. It mainly checks safety and early side effects in a small group of people.
  • Phase 2: A later trial stage that looks more closely at whether the study treatment works and continues safety checks.
  • Intranasal: Given through the nose.
  • Intramuscular: Given by injection into a muscle.
  • Booster dose: An extra dose given after earlier vaccination to strengthen the immune response.
  • Healthy volunteers: People who do not have the condition being studied and who join a trial to help test the study treatment.
  • Safety: How well a study treatment is tolerated and whether it causes unwanted medical events.
  • Immunogenicity: How strongly a vaccine or treatment makes the immune system respond.
  • Mucosal immune response: The immune response in the lining of the nose, mouth, and other body surfaces.
  • IgA: A type of antibody, which is a protein made by the immune system to help fight infection.
  • ELISA: A laboratory test used to measure specific substances in a sample, such as antibodies.
  • Adverse event: Any unwanted medical problem that happens during a study, whether or not it is caused by the treatment.
