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
NCT07710872 is Sanofi's Phase 3, modified-double-blind, multi-center study of an investigational quadrivalent meningococcal conjugate vaccine in healthy infants and toddlers aged 2 to 23 months in China, to "describe the safety and immunogenicity of MenACYW conjugate vaccine compared with locally-licensed meningococcal vaccines"[1]
The vaccines compared are MenQuadfi (Meningococcal Polysaccharide serogroups A, C, W and Y Tetanus Toxoid Conjugate Vaccine, Sanofi Pasteur Inc., Swiftwater, PA, USA) and Menhycia (ACYW135 Meningococcal Conjugate Vaccine CRM197, CanSino Biologics Inc., China), both given intramuscularly[1]
Estimated enrollment is 4,568 participants at 3 sites in China; the record's status is RECRUITING[1]
The trial started 2026-08-22 (actual), with primary completion estimated at 2028-03-13 and full completion at 2029-07-26; it was first posted 2026-07-17 and last updated 2026-09-09[1]
Seven groups run in three cohorts, each including a 6-month safety follow-up after the last dose: Cohort I approximately 211 or 271 days (about 7 or 9 months) on a 2-dose schedule; Cohort II up to 18 months on a 2-dose schedule with a booster at 18 months of age for Group 3 only; Cohort III Groups 5 and 6 up to 21 months on a 3-dose primary series plus a booster at 12 or 18 months of age; and Cohort III Group 7 approximately 16 months on a 3-dose series plus a booster at 12 months of age[1]
Primary outcomes are vaccine seroresponse to serogroups A, C, Y and W and antibody titers (GMTs) measured by rSBA - 30 days after the 2nd vaccination (up to Day 121) for Cohorts I and II, at Day 91 for Cohort III Groups 5 and 6, and at Day 151 for Cohort III Groups 7 and 6[1]
Telephone calls are planned on the 4th, 9th and 21st day after each vaccination including boosters, plus 5 monthly calls over the 5 months after the last on-site visit[1]

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

Boehringer Ingelheim's phase 3 trial of Vicadrostat in heart failure reaches primary completion, the point at which the last participant's primary outcome is measured. The trial enrolled 6,000 participants. This study is open to adults aged 18 or above legal age with heart failure. People can join the study if they have heart failure symptoms and a left ventricular ejection fraction (LVEF) of 40% or more. The purpose of this study is to find out whether vicadrostat (BI 690517) in combination with empagliflozin helps people with heart failure. Participants are put into 2 groups by chance. Every participant has an equal chance of being in each group. The groups are: * Vicadrostat/empagliflozin group: participants take vicadrostat/empagliflozin as tablets once a day. * Placebo/empagliflozin group: participants take placebo/empagliflozin as tablets once a day. Participants can stay in the study as long as they benefit from treatment and can tolerate it. During this time, they visit their doctors regularly. The doctors regularly check participants' health and take note of any unwanted effects. T

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

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.

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
