A Phase 3 interventional study of 2-doses Group among 9-14 years and 3-doses Group among 9-19 years in HPV Infections, Cervical Cancer Stage IIa and Vaginal Cancer, sponsored by Shanghai Bovax Biotechnology Co., Ltd.. Recruiting at 1 site in China. Open to female participants aged 9 Years to 26 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2024-04-17.

This phase 3 study will evaluate the immunogenicity and safety of Quadrivalent HPV recombinant vaccine in Chinese females aged 9 to 26 years
This is a singel-center study (protocol 4-HPV-3002) in which women are planned to receive q-HPV vaccine. Study participation will last approximately 60 months and involves a total of nine or eleven scheduled visits.
This study will also assess whether the immunogenicity of the q-HPV vaccine given 2-dose schedule in 9-14 year old girls is noninferior to that in young women, aged 20-26, receiving 3 doses, and 3 doses in 9-19 year old girls is noninferior to that in young women receiving 3 doses, while assessing the safety of this vaccine.
116 studies on the registry are indexed under Condylomata Acuminata; 11 are open to participants now.
This study's planned enrollment of 1,348 is above the median of 158 across 95 interventional studies indexed under Condylomata Acuminata.

Compared within Condylomata Acuminata, this study's primary condition as ClinicalTrials.gg classifies it; the registry's first condition term is Papillomavirus Infections. The counts are of registry records indexed under each term, refreshed daily. How we classify →

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.
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.
A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.
Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.
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.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
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.
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.
Vaccines made with a weakened form of the germ, such as measles–mumps–rubella (MMR), chickenpox and yellow fever. They can be risky when the immune system is weakened. Flu injections are not live; the nasal flu spray is.

Ran from Sep 2021 to primary completion in Nov 2023, 26 months.
Of 28 phase 3 interventional studies under Condylomata Acuminata, half reached primary completion within 24 months of starting (the median), counting those still running; a quarter within 15 and three quarters within 61. This study's 26 months is close to that.
