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
NCT07071623 (MK-8527-010) is Merck Sharp & Dohme's Phase 3, randomized, active-controlled, double-blind study of oral MK-8527 taken once monthly as HIV-1 pre-exposure prophylaxis in women[1]
The goals are to learn whether once-monthly MK-8527 prevents HIV-1 infection better than a standard once-daily PrEP, and to assess the safety and tolerability of MK-8527; the comparator is daily emtricitabine/tenofovir disoproxil (FTC/TDF), with double-dummy placebos matched to each tablet[1]
Estimated enrollment is 4,580 participants across 30 sites in Kenya, South Africa and Uganda; the record's status is RECRUITING[1]
The trial started 2025-11-10 (actual), with primary completion and completion both estimated at 2027-10-18; it was first posted 2025-07-17 and last updated 2026-09-18[1]
Primary outcomes, each over up to about 2 years, are the number of participants with adjudicated HIV-1 infection, the number experiencing at least one adverse event, and the number discontinuing study intervention because of an adverse event[1]

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

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
