A Phase 3 interventional study of Recombinant Herpes Zoster Vaccine and Recombinant Herpes Zoster Vaccine Placebo in Vaccine-Preventable Diseases and Herpes Zoster, sponsored by Beijing Luzhu Biotechnology Co., Ltd.. Recruiting at 1 site in China. Open to participants aged 40 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2023-10-18.
Sponsored by Beijing Luzhu Biotechnology Co., Ltd. · Phase 3, Interventional, and Prevention
This clinical trial is to study protective efficacy and safety of a recombinant herpes zoster vaccine (LZ901) and sponsored by Beijing Luzhu Biotechnology Co., Ltd. It is a phase Ⅲ, randomized, double-blind, placebo-controlled in healthy people aged 40 years and older. The study is to protect adults against shingles (herpes zoster / varicella zoster virus(VZV)). There will be about 26000 participators who will receive two-dose injection at the upper arm.
LZ901 vaccine is made up of a tetramer of VZV glycoprotein E (VZV gE-Fc) and adsorbed with aluminum hydroxide adjuvant. This adjuvant can raise the immune response to a lot of antigens. It is the most widely used and safe adjuvant in various types of vaccines worldwide.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
Exclusion Criteria:
to any of the components of the test vaccine: or prior hypersensitivity to any recombinant vaccine of CHO cell origin [e.g., recombinant vaccine (CHO cell)], polysorbate, etc.; or prior history of severe allergy* to any of the vaccinations;
*Severe allergies: anaphylaxis, anaphylactic laryngeal edema, anaphylactic purpura, thrombocytopenic purpura, localized anaphylactic necrotic reaction (Arthus reaction), severe urticaria.
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.
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.
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.
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.
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.
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.

The active ingredient of the recombinant herpes zoster vaccine is varicella-zoster virus glycoprotein E fusion protein expressed in CHO cells by gene recombination technology. The LZ901 cell line carrying this gene is cultured in chemically defined medium. The harvest cell culture is purified by multi-step liquid chromatography. After Low pH incubation and virus removal filter package Nanofiltration inactivation/virus removal process, the bulk containing high-purity recombinant herpes zoster virus glycoprotein E is obtained. Finally, an alumina adjuvant is added to the formulated final product.
