Researchers are evaluating new treatment options for adults with locally advanced or metastatic colorectal cancer that cannot be removed by surgery and has a specific KRAS G12C gene mutation. This study compares the safety and effectiveness of adding calderasib and cetuximab, both targeted therapies, to a standard chemotherapy regimen called mFOLFOX6. The goal is to see if this combination can help patients live longer without their cancer growing or spreading compared to current treatments that may include mFOLFOX6 with or without bevacizumab. The study has two parts. It involves treatment with calderasib taken as an oral tablet, cetuximab given according to standard procedures, and mFOLFOX6 chemotherapy combining oxaliplatin, leucovorin/levofolinate calcium, and 5-fluorouracil. Some participants may receive bevacizumab or a bevacizumab biosimilar as part of the comparison. The treatments are given following approved dosing schedules. This design allows researchers to assess the safety and tolerability of these drug combinations in treating this type of colorectal cancer with the KRAS G12C mutation. Participants will be monitored for side effects, treatment tolerability, and cancer progression over a period that may last up to about 44 months. Researchers will track outcomes such as how many participants experience dose-limiting toxicities or adverse events, how many stop treatment due to side effects, and progression-free survival time. Assessments include health evaluations, laboratory tests, and imaging to observe cancer status. This long-term follow-up aims to understand both safety and effectiveness of the treatment combinations.

Researchers are evaluating the safety and effectiveness of combining durvalumab and domvanalimab compared to durvalumab plus placebo in adults with locally advanced (Stage III), unresectable non-small cell lung cancer (NSCLC) whose disease has not worsened after definitive platinum-based concurrent chemoradiation therapy. This Phase III, randomized, double-blind, placebo-controlled, international study involves multiple centers. Participants receive intravenous infusions of durvalumab and domvanalimab or durvalumab and placebo. The treatments are given after patients have completed concurrent platinum-based chemotherapy and radiation therapy with a total radiation dose of approximately 60 Gy. The study monitors patients over time to assess treatment effects and safety. During the study, participants undergo evaluations including tumor tissue analysis for PD-L1 status, performance status assessments, and monitoring of organ and marrow function. The main outcome measured is progression-free survival up to 8 years after randomization. Researchers also monitor for any adverse effects and disease progression throughout the study period.

This trial investigates the safety and effectiveness of rilvegostomig combined with fluoropyrimidine and trastuzumab deruxtecan (T-DXd) compared to trastuzumab, chemotherapy, and pembrolizumab in adults with HER2-positive locally advanced or metastatic gastric or gastroesophageal junction (GEJ) adenocarcinoma whose tumors express PD-L1 with a combined positive score of 1 or higher. Additionally, rilvegostomig combined with trastuzumab and chemotherapy is studied separately to understand each component's contribution. This Phase 2, randomized, open-label, global study is conducted at 200-250 sites in about 25 countries. Participants are randomly assigned to one of three arms: Arm A receives rilvegostomig, fluoropyrimidine, and T-DXd; Arm B receives trastuzumab, chemotherapy, and pembrolizumab; Arm C receives rilvegostomig, trastuzumab, and chemotherapy. Treatments are administered mostly by intravenous infusion every three weeks, with capecitabine given orally twice daily. The study compares these treatment regimens to evaluate their effects on the cancer. Throughout the study, participants undergo assessments including tumor measurements, organ function tests, and heart function evaluation to ensure safety and monitor disease progression. The main outcomes measured are progression-free survival and overall survival for up to approximately six years. Researchers will also monitor adverse events and overall health status during and after treatment.

Researchers are evaluating the effectiveness of camizestrant compared to standard endocrine therapy in patients with early breast cancer that is estrogen receptor positive (ER+) and human epidermal growth factor receptor 2 negative (HER2-). These patients have an intermediate or high risk of cancer recurrence and have already completed local treatments such as surgery and possibly chemotherapy, alongside at least 2 years and up to 5 years of standard adjuvant endocrine therapy. The study is a Phase III, open-label trial designed to assess outcomes over a long term. Participants will be randomly assigned to receive either camizestrant, an oral selective estrogen receptor degrader, or one of several standard endocrine therapies including tamoxifen, anastrozole, letrozole, or exemestane, administered according to local approved guidelines. The treatment duration for both groups is planned to last 60 months. Eligible patients may have previously used CDK4/6 inhibitors, and the study will specifically include those with intermediate or high risk of recurrence as determined by clinical and biological markers. During the study, participants will be monitored for up to 10 years from the last patient's randomization to evaluate invasive breast cancer-free survival. Additional outcomes include invasive disease-free survival, distant relapse-free survival, overall survival, safety, and clinical outcome assessments. The study involves ongoing assessments of health status, treatment effects, and safety to determine the long-term benefits and risks of camizestrant compared to standard therapies.

This is a Phase III, randomized, open-label multicenter study that will evaluate the efficacy and safety of giredestrant compared with fulvestrant, both in combination with the investigator's choice of a CDK4/6 inhibitor (palbociclib, ribociclib or abemaciclib), in participants with estrogen receptor-positive (ER+), human epidermal growth factor receptor 2-negative (HER2-) advanced breast cancer who have developed resistance to adjuvant endocrine therapy.

Researchers are evaluating the safety and effectiveness of sacituzumab tirumotecan with or without bevacizumab compared to standard care in women with platinum-sensitive recurrent ovarian, fallopian tube, or primary peritoneal cancer. This phase 3 study aims to learn how well patients tolerate these treatments and whether they live longer without their cancer worsening. The study focuses on those who have already undergone second-line platinum-based chemotherapy and have specific cancer stages and types. Participants receive sacituzumab tirumotecan and may also receive bevacizumab through intravenous infusion. Before sacituzumab tirumotecan, rescue medications such as H1 and H2 receptor antagonists, acetaminophen, dexamethasone, and steroid mouthwash are given to help manage side effects. The study includes multiple treatment phases and compares these interventions to standard care. These treatments are administered under close medical supervision throughout the study. During the study, participants are monitored for adverse events and treatment tolerability over approximately six weeks in the first part, followed by progression-free survival tracking for up to about four years. Assessments include physical exams, performance status evaluations, and safety monitoring. Researchers also collect tumor tissue samples and conduct laboratory tests to evaluate treatment effects. The total participation time involves ongoing observation to measure safety and effectiveness outcomes.

This is a Phase III open-label study to assess if camizestrant improves outcomes compared to standard adjuvant endocrine therapy for patients with ER+/HER2- early breast cancer with intermediate-high or high risk for disease recurrence who completed definitive locoregional therapy (with or without chemotherapy). The planned duration of treatment in either arm of the study is 7 years. Eligible patients must have intermediate-high or high risk of recurrence as defined by specified clinical and biologic criteria. Concurrent use of abemaciclib is permitted in both arms. The primary endpoint of the study is Invasive breast cancer-free survival (IBCFS) and main secondary endpoints include Invasive disease-free survival (IDFS), Distant relapse-free survival (DRFS), Overall survival (OS), Safety and Clinical Outcome Assessments (COAs). Patients will be followed for 10 years from randomization of the last patient.

Approximately 1100 adult participants will be enrolled after central FRα testing into two independent cohorts (about 550 FRα-high and 550 FRα-low) and randomized 1:1 within each cohort to receive AZD5335 or the relevant standard of care (mirvetuximab soravtansine in FRα-high; investigator's choice single-agent chemotherapy in FRα-low). Participants will remain on assigned treatment and undergo regular tumor evaluations per RECIST v1.1 until disease progression or another reason for treatment discontinuation. All participants will be followed for overall survival. An independent data monitoring committee (IDMC) of external experts will periodically review unblinded safety and interim efficacy to confirm participant safety and study integrity.

Researchers are evaluating the effectiveness and safety of Zanidatamab combined with Cisplatin and Gemcitabine, with or without an added PD-1/L1 inhibitor (either Durvalumab or Pembrolizumab), as a first treatment for people with advanced HER2-positive biliary tract cancer. This study focuses on participants whose tumors show specific HER2 markers and aims to compare this combination to standard care. It is a Phase 3 trial involving patients with locally advanced or metastatic disease who have received limited prior treatment. Participants receive Zanidatamab, Cisplatin, and Gemcitabine all through intravenous (IV) infusions. Some may also receive a PD-1/L1 inhibitor chosen by their doctor, depending on local approvals. Treatments are given as part of the first-line therapy for advanced disease. The study includes screening to confirm HER2-positive status using biopsy tissue and standard imaging to assess the cancer. The study does not include a separate extension phase but follows participants during treatment and observation. During the trial, participants are monitored for progression-free survival for up to 52 months. Researchers will assess tumor response using standard criteria and regularly check participants' health, organ function, and side effects. Women of childbearing potential must have negative pregnancy tests and use birth control, and all participants must have a good performance status. Safety assessments, including laboratory tests and monitoring for adverse events, are ongoing throughout the study to ensure participant well-being.

Gallstones are common in women and are a major risk factor for gallbladder cancer (GBC), a serious disease with limited treatment options. This research aims to improve how well we can predict the risk of GBC and detect it early by studying differences in geography, environment, lifestyle, ethnicity, gender, and molecular markers. The goal is to develop better prevention programs and improve understanding of how lifestyle and genetic factors contribute to GBC development. The study involves collecting epidemiological, clinical, and dietary information, along with samples of blood, saliva, urine, bile, feces, and gallbladder tissue. These samples will be used to identify and study new biomarkers for GBC, build a biorepository, develop a risk scoring system, and explore new treatment options. The study includes patients with gallbladder cancer or precancerous conditions and those with gallstones scheduled for gallbladder removal. Participants will provide various samples and data which researchers will use to measure the number of participants developing gallbladder cancer or dysplasia, either at the start or after examination of removed gallbladders. The project also supports training researchers and aims to help shape health policies. The study is observational and does not involve any experimental treatments, focusing instead on gathering data to improve prevention, diagnosis, and future treatments for GBC.
