Researchers are evaluating the consistency of immune responses to three different batches of an investigational chickenpox vaccine called VNS vaccine in healthy children aged 12 to 15 months who have not had chickenpox or received a chickenpox vaccine before. The study also compares the safety and immune response of the VNS vaccine to an approved chickenpox vaccine known as Varivax. This Phase 3a study is sponsored by GlaxoSmithKline and aims to better understand the immune protection provided by these vaccines. Participants are randomly assigned to receive one dose of either one of the three investigational VNS vaccine lots or one of two lots of the marketed Varivax vaccine. Along with the chickenpox vaccine, they also receive one dose each of measles, mumps, and rubella MMR vaccine, hepatitis A vaccine HAV, and a pneumococcal conjugate vaccine PCV which could be PCV 13, Vaxneuvance, or PCV 20 depending on availability and country recommendations. All vaccines are given on Day 1 of the study. During the study, researchers monitor the participants immune responses by measuring antibodies against varicella zoster virus VZV and other vaccine components at Day 43. They also track safety by recording any side effects or adverse events from Day 1 to Day 181. The study includes diary reports by parents and regular clinical evaluations to assess immune response and safety outcomes. Participation involves a single vaccination visit and follow-up assessments over approximately six months.

Researchers are evaluating the safety and tolerability of a new multivalent pneumococcal vaccine called PG4 compared to the currently used 20-valent pneumococcal conjugate vaccine 20vPnC in healthy infants about 2 months old. The study aims to see if the new vaccine is as safe as the existing one and whether it can provide additional protection against infections caused by the Streptococcus pneumoniae germ, including pneumonia, meningitis, and ear infections. This is a phase 3, randomized, double-blinded trial conducted by Pfizer focused on prevention of pneumococcal disease. About 2400 infants will be randomly assigned to receive either the PG4 vaccine or the 20vPnC vaccine. Vaccinations are given by injection into the left thigh muscle at 2, 4, 6, and between 12 to 15 months of age. The study consists of two groups receiving these vaccines according to this schedule. The treatment period spans these vaccination times, with a total participation duration of about 16 to 19 months. During the study, infants will have six clinic visits and one phone call for monitoring. Parents or legal guardians will report any side effects or adverse events their infant experiences after vaccinations. Researchers will evaluate local and systemic reactions within 7 days of each dose, adverse events from the first dose through one month after the third and fourth doses, and serious adverse events up to six months after the last dose. Safety and tolerability data will be collected throughout the study period.

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.

Researchers are evaluating whether adding the immunotherapy drug durvalumab to the usual chemotherapy regimen can improve outcomes for patients with MammaPrint High 2 Risk MP2 stage II-III hormone receptor positive, HER2 negative breast cancer. This phase III trial focuses on comparing breast cancer event-free survival and other measures between patients receiving chemotherapy alone and those receiving chemotherapy with durvalumab. Immunotherapy may help enhance the bodys immune response against cancer, while chemotherapy works to stop tumor growth in various ways. Participants are first tested for MP2 status using MammaPrint on previously collected tissue. Those with MP2 results are randomized into two groups. One group receives paclitaxel intravenously on days 1 and 8 every 14 days for six cycles, followed by doxorubicin and cyclophosphamide intravenously every 14 days for four cycles. The other group receives the same chemotherapy schedule combined with durvalumab given intravenously over 60 minutes on specific cycles. Mammography and optional tumor tissue and blood sample collections occur during the study. During the study, participants undergo assessments including mammography, tumor biopsies, blood tests, and quality-of-life questionnaires. Researchers measure outcomes such as event-free survival, response rates, relapse-free survival, overall survival, treatment side effects, and patient-reported fatigue and physical health. After treatment completion, participants are followed for up to 10 years to monitor long-term outcomes and survival. Specimens are also banked for future research.

Researchers are evaluating the combination of capivasertib with CDK46 inhibitors and fulvestrant in adults with hormone receptor-positive and HER2-negative locally advanced or metastatic breast cancer. This Phase IbIII study aims to determine the safe dose for the combination treatment in the initial Phase Ib part and then compare its effectiveness and safety to standard treatment in the Phase III part in participants who have not received prior endocrine therapy in the advanced setting. In the Phase Ib portion, participants receive capivasertib combined with one of the CDK46 inhibitorspalbociclib, ribociclib, or abemacicliband fulvestrant to establish recommended doses. In the Phase III part, participants are randomly assigned to receive either capivasertib plus fulvestrant with a chosen CDK46 inhibitor palbociclib or ribociclib or fulvestrant with a CDK46 inhibitor alone. Treatments are given in 28-day cycles with specific dosing schedules for each drug, including oral doses of capivasertib and CDK46 inhibitors and injections of fulvestrant. Participants undergo screening and regular monitoring throughout the study, including assessments of treatment side effects, tumor progression, and blood samples for pharmacokinetics and biomarker analysis. The primary outcomes include dose-limiting toxicities and adverse events in Phase Ib and progression-free survival in Phase III, with follow-up lasting up to several years to evaluate overall survival, response rates, physical functioning, and quality of life.

Researchers are evaluating how to best recommend chemotherapy for patients with Stage IIB, IIC, or Stage III colon cancer based on the presence or absence of circulating tumor DNA ctDNA after surgery. This Phase IIIII trial explores whether ctDNA status can help guide decisions about the need for adjuvant chemotherapy and identify the optimal chemotherapy regimen for those at high risk of recurrence. Circulating tumor DNA is a promising biomarker that may detect microscopic residual cancer cells that traditional methods might miss. Participants are assigned to groups based on their ctDNA results after surgery. Those without detectable ctDNA ctDNA- may undergo serial monitoring without treatment or receive different chemotherapy regimens such as mFOLFOX6 or CAPOX for 3 to 6 months. Patients with detectable ctDNA ctDNA who have a higher risk of recurrence are randomized to receive either standard chemotherapy regimens like mFOLFOX6 or CAPOX for 6 months or a more intensive regimen called mFOLFIRINOX for 6 months. Central ctDNA testing is performed using the Signatera test to guide these assignments. During the study, participants have blood samples collected for ctDNA testing and undergo imaging scans to check for cancer recurrence. Researchers assess disease-free survival, overall survival, and chemotherapy compliance over several years. The study includes monitoring for safety and treatment effects, with follow-up planned for up to 5 years after randomization. Participants health status, laboratory tests, and tumor markers are regularly evaluated throughout the treatment and follow-up periods.

Researchers are comparing two treatment approaches for patients with stage II-IIIB non-small cell lung cancer NSCLC that can be removed by surgery. The study evaluates whether giving standard therapy before and after surgery perioperative is better than giving it only after surgery adjuvant. This phase III trial focuses on chemotherapy and immunotherapy, which are current standard treatments aimed at controlling tumor growth and helping the immune system fight cancer. Patients are divided into two groups. One group undergoes surgery followed by chemotherapy and immunotherapy for up to one year if the disease does not progress or cause severe side effects. The other group receives chemotherapy combined with immunotherapy before surgery, then surgery, followed by immunotherapy alone for up to one year. Chemotherapy drugs may include cisplatin, carboplatin, pemetrexed, gemcitabine, docetaxel, or vinorelbine. Imaging tests like CT, MRI, or PETCT scans are done throughout the study. Participants will have surgery within a month of joining and receive treatments according to their assigned group. They will be monitored with scans and followed up every six months for up to 10 years to assess survival, disease progression, surgical outcomes, side effects, and immune responses. Researchers will measure event-free survival and overall survival as main results, as well as response rates and safety information over the long term.

Researchers are evaluating whether adding endocrine therapy to the usual chemotherapy and HER2-targeted therapy before surgery can improve treatment response in adults with hormone receptor-positive, HER2-positive breast cancer. This phase 2 study focuses on breast cancer patients who have not yet received treatment and aims to see if this combination increases the effectiveness of therapy at the time of surgery. Participants will receive concurrent endocrine therapy along with chemotherapy and HER2-directed therapy as part of their treatment before surgery. The choice of endocrine therapy will be decided by their physician, and it must begin before the second cycle of chemotherapy and HER2 therapy. The study includes patients with stage IIA to IIIC breast cancer who will undergo at least four cycles of TCHP chemotherapy. During the study, researchers will monitor participants for pathological complete response rates 21 months after treatment begins and assess residual cancer burden scores as a secondary outcome. Participants will be followed over this period to evaluate their response to therapy. Safety and treatment effects will be observed throughout, with ongoing assessments to understand how well the combined therapies work together.

Researchers are evaluating a treatment approach for early-stage hormone-sensitive, HER-2 negative breast cancer with an Oncotype recurrence score of 18 or less. This Phase III trial compares breast conservation surgery with endocrine therapy alone against breast conservation surgery with both radiation and endocrine therapy. The goal is to see if skipping radiation after lumpectomy is not worse in preventing cancer recurrence in the same breast. Participants will be randomly assigned to one of two groups. One group will receive radiation therapy to the breast plus at least five years of endocrine therapy with drugs such as Tamoxifen, Anastrozole, Letrozole, or Exemestane. The other group will receive endocrine therapy only for at least five years without radiation. Radiation must start within 12 weeks of surgery if assigned. Endocrine therapy dosing and schedule are determined by the treating doctor. During the study, participants will have regular follow-ups up to five years to monitor cancer recurrence in the breast and elsewhere, survival, and breast preservation. Assessments will include clinical exams, imaging like mammograms or MRI, and pathology reviews. The main outcome is time to invasive or noninvasive breast tumor recurrence within five years. Some measures will continue through an average of 15 years, including breast conservation rates. Safety and overall health will be monitored throughout and after treatment.

Researchers are evaluating the effectiveness and safety of fusidic acid 1% eye drops compared to a placebo for treating bacterial conjunctivitis in both adults and children. This Phase 3 clinical trial aims to show that fusidic acid 1% is superior to placebo in curing bacterial conjunctivitis and to further confirm its safety when applied topically to the eyes. Participants will be randomly assigned to one of two groups one group will apply one drop of fusidic acid 1% in each eye twice daily for seven days, and the other group will use a placebo eye drop with the same schedule. The doses are ideally spaced about 12 hours apart, but the twice-daily application schedule is prioritized over exact timing. During the study, participants will be assessed for clinical cure and microbial eradication at Day 4 and Day 8 visits. Researchers will monitor safety and treatment effects through these evaluations and by tracking any adverse events. The total participation duration covers at least the seven days of treatment plus follow-up assessments, helping establish both effectiveness and safety profiles for the treatment.
