Researchers are studying treatments for locally advanced or metastatic colorectal cancer mCRC that cannot be removed by surgery and has a specific KRAS G12C gene mutation. This trial aims to evaluate if adding the targeted therapies calderasib and cetuximab to the standard chemotherapy regimen mFOLFOX6 can provide better outcomes compared to mFOLFOX6 with or without bevacizumab. The study focuses on the safety and tolerability of these combinations and whether they can help people live longer without their cancer growing or spreading. Participants will be assigned to one of two groups. One group will receive calderasib orally, cetuximab every two weeks, and mFOLFOX6 chemotherapy including oxaliplatin, leucovorin or levofolinate calcium, and 5-fluorouracil every two weeks. The other group will receive mFOLFOX6 chemotherapy with or without bevacizumab every two weeks, based on the investigators decision. Treatments will continue until certain stopping criteria are met. During the study, participants will be monitored for side effects and treatment tolerance, with regular assessments of cancer progression. Researchers will measure outcomes such as dose-limiting toxicities, adverse events, progression-free survival, and overall survival. Quality of life will also be evaluated through questionnaires. The study may last up to several years, with monitoring continuing for safety and effectiveness throughout the treatment period and follow-up.

Researchers are evaluating new treatments for advanced ovarian cancer in women who have completed initial surgery and chemotherapy. The study focuses on non-HRD positive ovarian cancer, comparing a targeted therapy called sacituzumab tirumotecan sac-TMT given alone or with bevacizumab, against standard care options such as bevacizumab maintenance or observation. The goal is to see if sac-TMT with or without bevacizumab can help patients live longer without their cancer worsening. Participants in the experimental group will receive sac-TMT through intravenous infusion on days 1, 15, and 29 of every 6-week cycle until the cancer progresses, side effects become prohibitive, or other reasons for stopping arise. They may optionally receive bevacizumab on days 1 and 22 of each cycle. The comparator group will either receive bevacizumab alone every 3 weeks for up to 22 courses or be monitored without active treatment. Supportive medications like steroid mouthwash and other rescue drugs are recommended before sac-TMT infusions. Throughout the study, participants will be regularly monitored for how long they live without their disease progressing, overall survival, side effects, and quality of life using specialized questionnaires. These assessments will continue for up to approximately 78 months. The study is randomized, with single masking, and led by Merck Sharp & Dohme LLC. Participants can expect regular visits for treatment and monitoring during this period.

Researchers are evaluating the efficacy and safety 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 progressed after definitive platinum-based concurrent chemoradiotherapy cCRT. This Phase III, randomized, double-blind, placebo-controlled, international study aims to provide new insights into treatment options for this patient population. Participants will receive either durvalumab and domvanalimab or durvalumab plus placebo as intravenous infusions every four weeks, beginning on Day 1 and continuing for up to 12 months. The study includes two groups one receiving the combination of durvalumab and domvanalimab, and the other receiving durvalumab with a placebo. Both treatments are given through infusion to assess their effects on disease progression and safety. During the trial, participants will undergo regular assessments including monitoring progression-free survival for up to 8 years after randomization. Other measures include overall survival, response rates, duration of response, and various time-to-event outcomes related to disease progression and symptom deterioration. Researchers will also evaluate drug concentrations and immune responses approximately 12 weeks after the last dose. Participants can expect scheduled visits for infusions and evaluations as part of this long-term study.

Researchers are assessing the effectiveness and safety of rilvegostomig combined with fluoropyrimidine and trastuzumab deruxtecan 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 CPS 1. The study also evaluates rilvegostomig combined with trastuzumab and chemotherapy to understand the contribution of each treatment component. This is a Phase 2, randomized, open-label, global, multicenter trial sponsored by AstraZeneca. Participants are divided into three groups Arm A receives T-DXd, rilvegostomig, and fluoropyrimidine capecitabine or 5-FU Arm B receives pembrolizumab, trastuzumab, and chemotherapy either 5-FU plus cisplatin or capecitabine plus oxaliplatin Arm C receives rilvegostomig, trastuzumab, and chemotherapy 5-FU plus cisplatin or capecitabine plus oxaliplatin. Treatments are given by intravenous infusion every three weeks or oral administration twice daily for capecitabine. This setup allows comparison of different combinations to evaluate each drugs role. During the study, participants will be monitored for progression-free survival and overall survival up to about six years. Researchers will also assess response rates, duration of response, adverse events, pharmacokinetics, immunogenicity, and quality-of-life factors like eating difficulties and side-effect burden. The study involves regular assessments including tumor measurements and laboratory tests. Participation may last several years, with safety and efficacy closely followed throughout this time.

Researchers are evaluating camizestrant against standard endocrine therapy for patients with ER-positive, HER2-negative early breast cancer who have an intermediate or high risk of disease recurrence. These patients must have completed locoregional therapy and at least 2 to 5 years of standard adjuvant endocrine therapy. The study is a Phase III open-label trial focused on improving outcomes for these patients over a long-term period. Participants are randomly assigned to receive either camizestrant orally or continue with the standard endocrine therapy chosen by their investigator, which may include aromatase inhibitors exemestane, letrozole, anastrozole or tamoxifen. Treatment in each group lasts for 60 months. The study allows prior use of CDK46 inhibitors and includes a follow-up period extending up to 10 years from the last patient randomization. During the study, participants will undergo regular assessments to monitor invasive breast cancer-free survival and other outcomes such as invasive disease-free survival, distant relapse-free survival, overall survival, and safety. Researchers will also evaluate symptoms like joint pain, hot flushes, and vaginal dryness using specific scales, along with quality of life measures and pharmacokinetics. Safety monitoring continues up to 28 days after the last dose, and participants remain under observation for up to 10 years total.

Researchers are conducting a Phase III, randomized, open-label multicenter study to evaluate the effectiveness and safety of giredestrant compared with fulvestrant. Both drugs are combined with the investigators choice of a CDK46 inhibitor palbociclib, ribociclib, or abemaciclib in participants with estrogen receptor-positive ER, HER2-negative advanced breast cancer who have become resistant to prior adjuvant endocrine therapy. Participants will be randomly assigned to one of two groups one group will receive giredestrant 30 mg orally daily on Days 1-28 of each 28-day cycle, while the other will receive fulvestrant 500 mg intramuscularly on Days 1 and 15 of Cycle 1 and Day 1 of subsequent 28-day cycles. Both groups will also receive a CDK46 inhibitor chosen by the investigator, with dosing schedules depending on the specific inhibitor selected. Preperimenopausal women and men will receive a luteinizing hormone-releasing hormone LHRH agonist during treatment. Participants will be assessed for progression-free survival over up to 5 years, with additional measures including overall survival, response rates, duration of response, clinical benefit, and quality of life. Safety will be monitored through adverse event reporting, vital signs, and laboratory tests during treatment and up to 28 days after the last dose. The study is led by Hoffmann-La Roche and aims to provide detailed information on the treatments effects in this patient population.

This trial focuses on people with platinum-sensitive recurrent ovarian cancer, including certain types of ovarian, primary peritoneal, or fallopian tube cancers. It aims to study the safety and tolerance of sacituzumab tirumotecan combined with bevacizumab and compare how long participants live without their cancer worsening when treated with sacituzumab tirumotecan, with or without bevacizumab, versus standard care. The study is a Phase 3, randomized, open-label trial designed to evaluate these treatments after second-line platinum-based chemotherapy. Participants are assigned to one of three groups one group receives sacituzumab tirumotecan plus bevacizumab through intravenous infusions every 2 and 3 weeks respectively for 6 weeks another group receives sacituzumab tirumotecan alone every 2 weeks for up to about 2 years or until the disease progresses, with optional bevacizumab at the doctors choice the third group follows the local standard care until progression, with optional bevacizumab as determined by the physician. The study includes rescue medications such as H1 and H2 receptor antagonists, acetaminophen, dexamethasone, and steroid mouthwash taken as needed according to approved guidelines. During the study, participants will be monitored for adverse events up to 6 weeks in Part 1 and for progression-free survival for up to about 4 years in Part 2. Additional assessments include overall survival for up to 6 years and quality of life measures through questionnaires at baseline and periodically up to approximately 4 years. Safety and treatment tolerability will be closely tracked, and participants will have intravenous infusions and follow-up visits throughout the study period, which may last several years depending on disease progression and treatment continuation.

This research aims to evaluate the effectiveness of AZD5335 compared to standard treatments in women with high-grade, platinum-resistant epithelial ovarian, fallopian tube, or primary peritoneal cancer. The study focuses on whether AZD5335 improves progression-free survival PFS among participants with either high or low levels of folate receptor alpha FR. Approximately 1100 adult women will be enrolled and divided into two groups based on their FR levels. Participants will be randomized within each group to receive either AZD5335 or the relevant standard treatment. Those with high FR levels will receive AZD5335 or mirvetuximab soravtansine, while those with low FR levels will receive AZD5335 or a chemotherapy agent chosen by the investigator, including paclitaxel, pegylated liposomal doxorubicin, or topotecan. Treatments are given intravenously, and participants will continue treatment until disease progression or other reasons for stopping. During the study, participants will undergo regular tumor assessments to monitor disease status. Researchers will follow all participants over time to evaluate overall survival. Safety and efficacy data will be reviewed periodically by an independent committee. The primary outcome is progression-free survival, measured for up to about five years. The study completion is expected by late 2029.

Researchers are evaluating the effectiveness and safety of combining Zanidatamab with the standard chemotherapy treatment Cisplatin and Gemcitabine CisGem, with or without a PD-1L1 inhibitor either Durvalumab or Pembrolizumab, for adults with advanced human epidermal growth factor receptor 2 HER2-positive biliary tract cancer. This phase 3 study focuses on participants with locally advanced or metastatic disease who have received limited prior therapy. Participants are randomly assigned to receive either Zanidatamab plus CisGem with or without a PD-1L1 inhibitor chosen by their physician, or CisGem with or without the PD-1L1 inhibitor alone. All drugs are administered intravenously. The study compares these two treatment approaches to assess their impact on disease progression and overall survival. Throughout the study, participants undergo regular assessments including tumor evaluations based on RECIST 1.1 criteria, physical functioning and symptom questionnaires, and monitoring for adverse events. The main outcome measured is progression-free survival in participants with HER2 IHC 3 tumors over up to 52 months, with additional outcomes including overall survival and treatment response tracked for up to 68 months. Safety and immune response are also monitored during this period.

Gallbladder cancer GBC is a serious disease often linked to gallstones, especially in women. This research focuses on improving the early detection and prevention of GBC by studying various factors including geography, environment, lifestyle, ethnicity, gender, and molecular markers. The goal is to better estimate the risk of developing GBC and to help guide prevention and treatment decisions, supported by a European-Latin American research collaboration. Participants include those with gallbladder cancer or dysplasia, both before and after starting treatment, as well as individuals with gallstones scheduled for gallbladder removal surgery. The study involves collecting epidemiological, clinical, and dietary data along with biological samples such as blood, saliva, urine, bile, feces, and gallbladder tissue to identify and study new biomarkers and risk factors for GBC. Throughout the study, researchers will use this information to build a biorepository and develop a risk score that integrates multiple factors linked to GBC. They will monitor participants for the development of gallbladder cancer or dysplasia through standard hospital protocols. The study aims to support future personalized prevention strategies and targeted therapies while training new researchers in precision medicine for GBC. Participation involves data and sample collection with ongoing follow-up to assess disease development.
