A Phase 3 interventional study of NmCV-5 and Menactra in Meningococcal Meningitis, sponsored by Serum Institute of India Pvt. Ltd.. Completed at 2 sites in 2 countries. Open to participants aged 2 Years to 29 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2021-07-27.
Sponsored by Serum Institute of India Pvt. Ltd. · Phase 3, Interventional, and Prevention
This observer-blind, randomized, active controlled trial will be conducted among 2-29 year olds in two sites (Mali and The Gambia). The objectives of the study are to assess and compare the immunogenicity and safety of NmCV-5 with that of Menactra.
A total of 1800 eligible participants (who or their parents/guardians have given written informed consent) will be randomised 2:1 (NmCV-5: Menactra) in each of the three age strata 18-29 years, 11-17 years \& 2-10 years (400 NmCV-5 recipients \& 200 Menactra recipients in each age strata).
Each subject will receive a single dose of study vaccine and will be followed up for 6 months post vaccination during which solicited reactions (for seven days), unsolicited AEs (28 days) and SAEs (until the end of study i.e. 168 days after vaccination) will be collected. A blood sample will be collected at baseline (pre-vaccination) and at day 28 post-vaccination for immunogenicity assessment by a Serum Bactericidal Activity assay using rabbit complement (rSBA).
125 studies on the registry are indexed under Meningitis, Meningococcal; 10 are open to participants now.
This study's enrollment of 1,800 is above the median of 538 across 113 interventional studies indexed under Meningitis, Meningococcal.

Exclusion Criteria:
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.
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.
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.
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.
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.
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.
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.
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.
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.
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 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.
