Researchers are evaluating HLX22 combined with trastuzumab and chemotherapy as a first-line treatment for patients with HER2-positive locally advanced or metastatic adenocarcinoma of the gastric or gastroesophageal junction. This phase 3, randomized, double-blind study compares this combination against trastuzumab plus chemotherapy with or without pembrolizumab. The trial aims to assess the efficacy and safety of adding HLX22 in this patient population. Participants will be randomly assigned in a 11 ratio to either the experimental group receiving HLX22 15 mgkg plus trastuzumab and chemotherapy XELOX with or without a placebo for pembrolizumab every three weeks, or the control group receiving placebo for HLX22 plus trastuzumab and chemotherapy XELOX with or without pembrolizumab also every three weeks. Treatment continues until clinical benefit is lost, intolerable side effects occur, death, withdrawal, or other protocol-specified reasons. Throughout the study, participants will have their disease progression monitored by an independent radiology review committee using RECIST v1.1 criteria for up to five years, along with overall survival and response rates. Safety will be regularly assessed by tracking adverse events. The study includes multiple assessments to evaluate treatment effects, and participants will be followed for long-term outcomes during the trial period.

Non-small cell lung cancer NSCLC is a condition where cancer cells grow uncontrollably in the lung tissues. This study evaluates the safety of an investigational drug called telisotuzumab vedotin in adults with previously treated NSCLC that overexpresses c-Met. The trial also monitors changes in disease activity and side effects over time. Participants will be randomly assigned to receive one of three different doses of telisotuzumab vedotin through intravenous IV infusion. Each dose group receives treatment as part of a study lasting up to three years. The study involves approximately 150 adults with c-Met positive NSCLC across many sites worldwide. Throughout the study, participants will attend regular hospital or clinic visits where they undergo medical assessments, blood tests, and complete questionnaires to evaluate how the drug affects their disease and any side effects experienced. The study measures treatment-related adverse events, disease response, and survival outcomes over the three-year period.

Researchers are evaluating the safety and effectiveness of Armour Thyroid compared to synthetic T4 in adults with primary hypothyroidism who have been stable on synthetic T4 treatment. The study will also assess how well patients tolerate switching from synthetic T4 to Armour Thyroid. This trial is a Phase 23, randomized, double-blind study sponsored by AbbVie to compare these two thyroid hormone replacement therapies. Participants will be randomly assigned to receive either Armour Thyroid or to alternate between Armour Thyroid and synthetic T4 for up to 81 weeks. The treatments are oral capsules or tablets taken daily, with doses carefully converted from their stable synthetic T4 dose. The study includes a dose-conversion period where dosage adjustments may be made to maintain appropriate thyroid hormone levels. During the study, participants will have regular blood tests to measure thyroid-stimulating hormone TSH levels, including at week 55 to see who achieves a target TSH response. Researchers will also monitor for any adverse events throughout the study, which lasts up to about 90 weeks. Dose adjustments and safety data will be tracked closely to understand treatment effects and tolerability over time.

Researchers are evaluating the safety and effectiveness of the InnAVasc Arteriovenous Graft IG for patients with end-stage renal disease ESRD who require hemodialysis and need an arteriovenous graft for vascular access. The study aims to measure the proportion of patients maintaining secondary patency of the graft at 6 months and to monitor adverse events related to the device during this period. Participants will receive the InnAVasc Arteriovenous Graft surgically implanted in the forearm or upper arm using standard vascular surgical techniques. The graft can be placed in a straight configuration in the upper arm or in a looped configuration in the forearm or upper arm, avoiding placement across the elbow. Patients must be able to continue or start antiplatelet therapy after the implant. The study includes periodic follow-up visits and assessments for up to two years after implantation. During the study, participants will undergo assessments to monitor graft function, safety, and successful use for hemodialysis. Researchers will collect data on device patency, adverse events, and the ability to cannulate the graft within seven days of surgery. Follow-up evaluations will continue at multiple time points up to 24 months to assess sustained graft use and patient outcomes. Participants are expected to provide informed consent and attend all scheduled visits throughout the study duration.

Researchers are evaluating the efficacy and safety of tezepelumab in adults with moderate to very severe chronic obstructive pulmonary disease COPD who are receiving inhaled maintenance therapy. This Phase 3, multicenter, randomized, double-blind, placebo-controlled study focuses on adults aged 40 to 80 years who have experienced multiple COPD exacerbations in the year prior to enrollment. The trial aims to assess tezepelumabs impact compared to placebo on COPD exacerbations and lung function. Participants will receive monthly subcutaneous injections of one of two doses of tezepelumab or a matching placebo. Treatment duration ranges from a minimum of 52 weeks to a maximum of 76 weeks. Following the treatment period, participants will undergo a 12-week off-treatment safety follow-up to monitor any lasting effects. Throughout the study, participants will be regularly assessed for COPD exacerbations, lung function changes measured by forced expiratory volume FEV1, and quality of life using questionnaires such as the St. Georges Respiratory Questionnaire and COPD Assessment Test. Blood samples will be collected to measure drug levels and immune responses. Safety and efficacy will be closely monitored, with total participation lasting up to approximately 88 weeks including follow-up.

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 studying the safety and immune response of a fifth dose of the Lyme disease vaccine called VLA15 in healthy individuals aged 7 years and older who have already received four doses of this vaccine. This Phase 3 trial compares the effects of the vaccine against a placebo saline to better understand its protection against Lyme disease. The study is randomized, placebo-controlled, and double-blinded, aiming to assess tolerability and immune response. Participants receive one injection, either VLA15 or saline, into the muscle of the upper arm at their first visit. They are randomized in a 51 ratio to either vaccine or placebo. The timing of the fifth dose varies, occurring either one or two years after the fourth dose from a previous study. The trial includes about 1712 participants and uses an independent data monitoring committee to oversee safety. During approximately 12 months of participation, individuals will attend four clinic visits. These visits include health checks, blood draws to measure immune response, and receiving the study injection during the first visit. Researchers will monitor local and systemic reactions within seven days post-injection, adverse events up to one month, and longer-term safety for up to a year. The main outcomes focus on immune responses to different parts of the vaccine and recording any side effects or new medical conditions.

Researchers are evaluating ovarian suppression in premenopausal women with hormone receptor-positive HR, HER2-negative advanced breast cancer. The study aims to assess how well ZOLADEX 10.8 mg suppresses ovarian function by measuring luteinizing hormone LH levels during treatment. This Phase 1, single-arm, open-label trial seeks to understand the degree and consistency of ovarian suppression in this patient group. Participants will receive two doses of ZOLADEX 10.8 mg as subcutaneous injections one on Day 1 Week 1 and another on Day 85 Week 12. The study focuses on tracking ovarian suppression by measuring hormone levels over the treatment period, with no placebo or comparison group involved. During the study, participants will have their LH levels measured at various time points, including Week 6 as the primary outcome and Weeks 12, 18, and 24 for secondary outcomes. Other assessments include estradiol suppression and absence of menses at these same intervals. Participants will be monitored for safety and treatment effects throughout the study which may last up to 24 weeks after treatment initiation.

Researchers are evaluating ziltivekimab, a new medicine not yet approved anywhere, to see if it can help people who were hospitalized due to a heart attack. The study aims to find out if ziltivekimab can reduce the development of heart disease and prevent future heart attacks or strokes. This is a Phase 3 clinical trial comparing ziltivekimab to a placebo in patients with acute myocardial infarction. Participants will receive an initial loading dose of ziltivekimab or matching placebo by injection under the skin as soon as possible after an invasive heart procedure, within 36 hours for STEMI or 48 hours for NSTEMI patients. After the loading dose, they will get monthly injections of the same study medicine for up to two years, in addition to their standard care. During the study, participants will be monitored for major cardiovascular events such as heart attack, stroke, and cardiovascular death. Researchers will also track other heart-related outcomes and safety measures over a period of up to 25 months. The study involves regular visits for injections, assessments, and laboratory tests to evaluate the medicines effects and patient health throughout the trial.

Researchers are evaluating treatments for older adults aged 70 and above with advanced stage IIIB-IV non-small cell lung cancer that expresses PD-L1 in 1-49% of tumor cells. This phase III trial compares the effects of adding chemotherapy to immunotherapy with pembrolizumab against pembrolizumab alone. The study aims to assess improvements in overall survival, progression-free survival, response rates, toxicity, quality of life, and explore geriatric assessment factors and gut microbiome correlations. Participants are randomly assigned to one of two groups. Arm A receives pembrolizumab intravenously every 21 days for four cycles, followed by maintenance pembrolizumab every 21 or 42 days for up to two years. Arm B receives the same pembrolizumab schedule plus one of several chemotherapy regimens, including combinations of pemetrexed, carboplatin, nab-paclitaxel, or paclitaxel administered intravenously on different schedules for four cycles, followed by pembrolizumab maintenance. Imaging with MRI, CT, and PET scans is performed at baseline and throughout the trial. During the study, participants undergo regular assessments including imaging scans to monitor disease status, blood tests, and quality of life questionnaires. After treatment completion, follow-up visits occur every three months for up to two years and then every six months up to five years. Researchers measure overall survival as the primary outcome and also track progression-free survival, response rates, adverse events, and patient-reported quality of life. Safety and tolerability are closely monitored along with exploratory analyses of chemotherapy dose intensity and microbiome factors.
