GSK's phase 3 trial of MRNA Seasonal Flu Vaccine in influenza, human reaches primary completion, the point at which the last participant's primary outcome is measured. The trial enrolled 54,000 participants. This study will compare an investigational mRNA flu vaccine with a licensed flu vaccine in adults 65 years of age and older. Participants will receive one injection and will be followed during the flu season. The study will measure prevention of laboratory-confirmed flu illness, side effects, and immune responses.
NCT07805707 is GlaxoSmithKline's Phase 3 study "A Phase 3 Randomized, Observer-Blind, Controlled Study to Evaluate the Clinical Efficacy of an mRNA Based Seasonal Influenza Vaccine in Older Adults 65 Years of Age and Older"[1]
It compares a single-dose intramuscular, season-adapted investigational mRNA seasonal flu vaccine against an age-appropriate, season-adapted licensed influenza vaccine as active comparator, with participants followed through the flu season[1]
Estimated enrollment is 54,000 participants across 163 sites in the United States; the record's status is RECRUITING[1]
The trial started 2026-09-02 (actual), with both primary completion and completion estimated at 2028-06-09; it was first posted 2026-09-04 and last updated 2026-09-18[1]
Primary outcomes are laboratory-confirmed protocol-defined influenza-like illness assessed by incidence rate ratio from Day 15 through the end of the influenza season, plus solicited administration-site and systemic adverse events (Day 1-7), unsolicited AEs (Day 1-28), serious AEs and adverse events of special interest (to the end of the season, with at least 180 days of follow-up), and laboratory abnormalities at Day 1 pre-dose and Day 29 post-dose[1]

Sanofi's phase 3 trial of MenQuadfi in meningococcal infection reaches primary completion, the point at which the last participant's primary outcome is measured. The trial enrolled 4,568 participants. The purpose of this study is to describe the safety and immunogenicity of MenACYW conjugate vaccine compared with locally-licensed meningococcal vaccines in healthy infants and toddlers in China. Study details include: * Study duration (including 6-month safety follow-up after the last dose): * Cohort I (Groups 1 and 2): approximately 211 or 271 days (approximately 7 or 9 months) * Cohort II (Groups 3 and 4): up to 18 months * Cohort III (Groups 5 and 6): up to 21 months * Cohort III (Group 7): approximately 16 months * Vaccination Visits Period: * Cohort I (Groups 1 and 2): a 2-dose vaccination at V01 (D01) and V02 (D31) or V03 (D91). Two blood samples are collected pre-vaccination (D01) and 30 days post the 2nd dose of vaccination (D61 or D121). Telephone calls (TCs) are planned on the 4th, the 9th, and the 21st day after each vaccination, and 5 TCs (1 TC/month) are planned for the 5 m

Sanofi's phase 3 trial of PCV21 Vaccine in pneumococcal immunization reaches primary completion, the point at which the last participant's primary outcome is measured. The trial enrolled 2,195 participants. This is a phase 3 randomized, modified double-blind study whose purpose is to measure whether 3 lots of the investigational pneumococcal vaccine PCV21 can help the body to develop germ-fighting agents called "antibodies" (immunogenicity) in a similar way (ie, same immune response) when they are given to infants aged from approximately 2 months (42 to 89 days) and are safe compared to a licensed 20-valent pneumococcal vaccine (20vPCV) (Prevnar 20™). The study duration per participant will be up to approximately 17 months. The study vaccines (either PCV21 or 20vPCV) will be administered at approximately 2, 4, 6 and 12 months of age. Cohort A will include randomization to three PCV21 formulation groups or one 20vPCV comparator group (Group 1-4, approximately 896 total participants), whereas Cohort B will include randomization to three PCV21 formulation groups only (Groups 1-3, approximately

Pfizer's phase 3 trial of PG4 in pneumococcal disease reaches primary completion, the point at which the last participant's primary outcome is measured. The trial enrolled 2,400 participants. The purpose of this study is to learn about the safety of a new pneumococcal vaccine and how the new pneumococcal vaccine helps to fight against germs that can cause pneumonia (lung infections), meningitis (brain infections), and otitis media (ear infections) in infants when compared to the pneumococcal vaccine that is currently in use, 20vPnC (Prevnar 20®). This study will test if the new pneumococcal vaccine is as safe as the one that is currently in use. This new vaccine can possibly provide additional protection against germs that cause pneumococcal disease that are not included in the vaccines that are currently given to infants. Pneumococcal disease includes a variety of infections caused by a specific germ, Streptococcus pneumoniae. There are two groups in this study. All participants will be assigned to one of the two groups. This study is seeking participants who are: \- infants

Merck & Co.'s phase 3 trial of MK-8527 in human immunodeficiency virus reaches primary completion, the point at which the last participant's primary outcome is measured. The trial enrolled 4,580 participants. Researchers are looking for new medicines to prevent HIV-1 (Human Immunodeficiency Virus Type 1) infection. The goals of this study are to learn: * If taking MK-8527 once a month works to prevent HIV-1 infection better than a standard (usual) pre-exposure prophylaxis (PrEP) taken once a day * About the safety of MK-8527 and if people tolerate it

Pfizer's phase 3 trial of C.Difficile Vaccine in clostridoides difficile associated disease reaches primary completion, the point at which the last participant's primary outcome is measured. The trial enrolled 32,500 participants. The purpose of the study is to learn about how effective, safe, and tolerable the Clostridioides difficile (C. difficile) vaccine is in decreasing the number of C. difficile infections (pCDI) in adults 65 years of age or older. The participants will receive either the C. difficile vaccine or placebo (saline). A placebo does not contain any active ingredients. The vaccines will be given as a shot into the upper arm muscle. This study looks at the number of diarrhea (loose stools) events related to a C. difficile infection, so the length of the study can change. If these events happen quickly, the study may finish sooner; if they happen slowly, it could take longer. Sometimes, the study might stop early if the vaccine clearly does not work. Participants will stay in the study until enough events have occurred to answer the main question. On average, each person is expected to take part for

AbbVie's phase 3 trial of Armour Thyroid in hypothyroidism reaches primary completion, the point at which the last participant's primary outcome is measured. The trial enrolled 2,800 participants. This study will evaluate the efficacy and safety of Armour Thyroid treatment compared with synthetic T4 in subjects who have primary hypothyroidism and are currently stabilized (i.e., in-range thyroid-stimulating hormone \[TSH\]) on synthetic T4 treatment. This study will also therefore evaluate the efficacy and safety of dose conversion from synthetic T4 therapy to Armour Thyroid therapy.

Amgen's phase 3 trial of Maridebart Cafraglutide in heart failure with preserved ejection fraction reaches primary completion, the point at which the last participant's primary outcome is measured. The trial enrolled 5,056 participants. This trial will examine if maridebart cafraglutide as an adjunct to standard of care will lead to a reduction in heart failure (HF) events such as HF hospitalizations and urgent HF visits, cardiovascular (CV) deaths and improvement in HF symptoms in participants with HF with preserved ejection fraction (HFpEF) and HF with mildly reduced ejection fraction (HFmrEF) who are obese. This is a phase 3, global, multicenter, 2-part trial with a double-blind period and an open-label extension (OLE). The trial is event-driven, and Part 1 will conclude when approximately 850 primary endpoint events have occurred.

The trial enrolled 2,330 participants. The purpose of the study is to evaluate whether ibuzatrelvir is effective and safe in adults and adolescents with COVID-19 who do not need to be in the hospital but who are at high risk for progression to severe disease. Eligible participants will be randomly assigned (by chance) to receive ibuzatrelvir or matching placebo orally for 5 days. Co-administration of locally available standard of care is allowed. The total duration of the study is around 6 months.
