Researchers are exploring new treatment options for neovascular age-related macular degeneration NVAMD, a condition affecting the eyes. This trial aims to compare a new medicine called tiespectus also known as MK-8748 or EYE201 with the standard treatment aflibercept to see if tiespectus works as well in treating NVAMD. The study includes adults aged 50 and older who have not previously received treatment for this condition. Participants will be randomly assigned to one of three groups tiespectus low dose, tiespectus high dose, or aflibercept. Those in the tiespectus groups will receive three initial injections every 4 weeks, followed by injections every 8 weeks up to week 48. After week 48, treatment will continue at intervals based on individual response until week 92. The aflibercept group will receive three initial injections followed by injections every 8 weeks until week 92. During the study, participants will have their vision tested using the Best-Corrected Visual Acuity BCVA score and their eye structure examined with imaging techniques. Researchers will monitor changes in vision over one year and track any side effects up to approximately 96 weeks. Participants will attend regular visits for treatment and assessments throughout the study period lasting about 92 weeks.

Researchers are evaluating the safety and immune response of a second dose of the RSVpreF vaccine in pregnant women during later pregnancies. The study also aims to understand how long the protection lasts from a single dose given during a previous pregnancy by examining blood samples from nonpregnant participants who had the vaccine before. This Phase 3 trial involves pregnant participants and their unborn babies, as well as nonpregnant participants previously vaccinated. Pregnant participants are divided into two groups one group who previously received RSVpreF in a Pfizer trial will get a second dose, and another group will be randomly assigned to receive either RSVpreF or a placebo if no prior antibody data exists. Infants born to these participants will be followed for six months to monitor safety and antibody levels. Nonpregnant participants who received RSVpreF in an earlier trial will provide blood samples to assess the durability of their immune response without receiving additional vaccine doses. Participants will undergo safety monitoring including tracking local and systemic reactions, adverse events, and serious events during pregnancy and after birth for infants. Blood tests will measure neutralizing antibodies against RSV types A and B at birth, 3 months, and 6 months. The study includes consent procedures for both pregnant participants and infants, and nonpregnant participants will have scheduled visits for blood sample collection. The total study duration extends through infant follow-up and ongoing immune response assessments.

Researchers are evaluating the safety, immune response, and preliminary clinical efficacy of a candidate vaccine for urinary tract infections UTIs in adults aged 18 to 64 years. This trial focuses on adults generally for safety and immune response, and specifically on females with a history of at least one confirmed E. coli UTI within the past year for clinical efficacy. The study includes two parts an initial dose-escalation safety phase and a proof-of-principle efficacy phase, designed to establish the highest tolerated dose and evaluate the vaccines impact on UTI occurrence. Participants receive one of several vaccine dose formulations or placebo administered by injection on Day 1 and Day 61. Part 1 involves healthy male and female adults and tests increasing antigen doses for safety. After safety review, Part 2 enrolls females with previous E. coli UTIs to assess vaccine efficacy compared to placebo over a 12-month period. The vaccine is given intramuscularly following a 0 and 2 months schedule. Throughout the study, participants are monitored for side effects at the injection site and systemic reactions during the first week after each dose, as well as for any adverse events up to 426 days from the first dose. Blood tests, pregnancy monitoring, and clinical exams are conducted. The main outcome measures include the frequency of adverse events and the rate of urine culture confirmed UTIs in females during the follow-up period. Participants are followed closely for safety and immune response, with the trial lasting over a year from initial vaccination.

Researchers are evaluating the study medicine PF-08046054 compared to the standard treatment docetaxel in adults with non-small cell lung cancer NSCLC that has PD-L1 expression of 1% or higher. These participants have cancer that has spread or cannot be treated with surgery or definitive radiation and have shown disease progression during or after previous treatments including PD-L1 or PD-1 inhibitors, platinum-based chemotherapy, and targeted therapies for known genomic alterations. The study is a randomized phase 3 trial assessing treatment options for advanced NSCLC. Participants are randomly assigned to one of two groups one receives PF-08046054 as an intravenous IV infusion twice during each 21-day cycle, and the other receives docetaxel as an IV infusion once every 21 days. The study treatment may continue for up to 5 years if the participants cancer responds to therapy. Both treatments are given in cycles, and participants receive the medicine through infusions during clinic visits. During the study, participants will have regular clinic visits to monitor their health and how well the treatment is working. Assessments include measuring overall survival, progression-free survival, tumor response rates, and quality of life through questionnaires. Safety is monitored for adverse events up to 90 days after treatment ends. Blood samples are also taken to study the medicines levels and immune response. The total study duration can be up to 5 years depending on individual responses and outcomes.

This trial studies adults with previously untreated locally recurrent inoperable or metastatic triple-negative breast cancer TNBC who are not eligible for PDL1 therapy based on PD-L1 negative disease. It is a Phase III, randomized, double-blind study comparing pumitamig with chemotherapy versus placebo with chemotherapy. The trial aims to evaluate the effects and safety of pumitamig in combination with chemotherapy for this patient group. Participants are randomly assigned to one of two groups one receives pumitamig plus a chemotherapy regimen chosen by their physician, and the other receives a matching placebo plus chemotherapy. Chemotherapy options include paclitaxelnab-paclitaxel, gemcitabine plus carboplatin, or eribulin, administered per standard care. The treatment period continues until disease progression, intolerable side effects, withdrawal, death, or trial end. After treatment, participants enter a safety follow-up for up to 90 days and a survival follow-up lasting until death, withdrawal, loss of contact, or sponsor decision. During the study, participants undergo screening lasting up to 28 days to confirm eligibility. They receive regular chemotherapy and study drug or placebo infusions during treatment. Researchers assess progression-free survival and overall survival up to about 32 and 49 months respectively. Other outcomes include response rates, quality of life, adverse events, and treatment tolerability. Safety monitoring continues after treatment, and survival is followed long-term. The total study participation can span several years depending on individual outcomes and follow-up.
