Study Endpoints

Primary Endpoints

Safety: local and systemic AEs (7-days-post)
During 7 days following each injection

To evaluate the safety and tolerability of vaccination with LTB-NG6 in healthy participants after each injection in vaccinees vs. placebo and by dose: \- Percentage of participants reporting each solicited local and systemic AE during the seven days after each injection (i.e., day of injection and the six subsequent days).

Safety: any events after each injection
During 28 days following each injection

To evaluate the safety and tolerability of vaccination with LTB-NG6 in healthy participants after each injection in vaccinees vs. placebo and by dose: * Percentage of participants reporting any adverse event (AE) following each injection * Percentage of participants reporting each severity level (Grade 1-4) of solicited local, systemic and unsolicited AEs following each injection

Safety: unsolicited AEs, SAEs, MAAEs
Through study completion, an average of 18 months

To evaluate the safety and tolerability of vaccination with LTB-NG6 in healthy participants after each injection in vaccinees vs. placebo and by dose: * Percentage of participants with unsolicited AEs. * Percentage of participants with serious adverse events (SAEs) following each injection. * Percentage of participants with medically attended adverse events (MAAEs) following each injection.

Immunogenicity - primary IgGs GMT
At 28 days after the second injection

To evaluate the immunogenicity of different doses of LTB-NG6 to identify the preferred dose(s). Serum IgG geometric mean titers (GMTs) against each of the N. gonorrhoeae antigens included in LTB-NG6 summarized by treatment group

Frequently asked questions about LTB-NG6

What is LTB-NG6 used for?

LTB-NG6 is an investigational monoclonal antibody being developed for the prevention of Neisseria gonorrhea infection. It is currently in Phase 1 clinical development, meaning it has not yet been approved for any use and is still being studied for safety and immunogenicity in healthy volunteers.

What does LTB-NG6 target?

LTB-NG6 is a monoclonal antibody designed to target Neisseria gonorrhea, the bacterium that causes gonorrhea. As a monoclonal antibody, it is intended to bind to specific components of the bacteria to help prevent infection, though the precise molecular target has not been disclosed.

Who makes LTB-NG6?

LTB-NG6 is being developed by Novo Nordisk A/S, a pharmaceutical company traded on the stock exchange under the ticker NVO. The company is conducting a Phase 1 clinical trial to evaluate the safety and immunogenicity of this investigational antibody.

What phase is LTB-NG6 in?

LTB-NG6 is in Phase 1 clinical development. It is an investigational drug, meaning it is not FDA approved and is still being tested in clinical trials. The current Phase 1 study is recruiting participants to assess the safety and immune response of the antibody in healthy volunteers.

What clinical trials is LTB-NG6 in?

LTB-NG6 is being studied in a Phase 1 clinical trial registered as NCT07758972, titled 'Safety and Immunogenicity Study of a Multivalent Gonorrhoea Vaccine.' This randomized, double-blind, placebo-controlled trial is recruiting 142 healthy volunteers in Germany, with participants aged 18 years and older.

Is LTB-NG6 the same as a gonorrhea vaccine?

LTB-NG6 is a monoclonal antibody, not a vaccine. However, it is being studied in a clinical trial titled 'Safety and Immunogenicity Study of a Multivalent Gonorrhoea Vaccine,' which may involve multiple components. The trial is evaluating the safety and immune response of the investigational product in healthy volunteers.
