Researchers are evaluating two surgical procedures, bilateral salpingectomy and bilateral salpingo-oophorectomy, to see how well they reduce the risk of ovarian cancer in women who have BRCA1 gene mutations. The study aims to determine if removing just the fallopian tubes (bilateral salpingectomy) is almost as effective as removing both the fallopian tubes and ovaries (bilateral salpingo-oophorectomy) in lowering ovarian cancer risk. This trial also assesses symptoms related to estrogen loss, quality of life, sexual function, cancer-related distress, decision-making about surgery, and treatment side effects in these patients. Participants choose between two groups: one group undergoes bilateral salpingectomy and may have their ovaries removed later, while the other group undergoes bilateral salpingo-oophorectomy. Both groups receive pelvic or transvaginal ultrasounds or pelvic MRI scans during screening, and blood samples are collected throughout the trial. Ancillary studies include quality-of-life assessments and questionnaires. The study also collects tissue and blood samples for future research. After surgery, participants have follow-up visits at 10 to 60 days, then at 6, 12, and 24 months, and annually for up to 20 years. Researchers monitor the time until any high-grade serous carcinomas develop, specifically ovarian, primary peritoneal, or fallopian tube cancers. They also track menopausal symptoms, sexual function, quality of life, cancer distress, medical decisions about surgery, and any adverse events during this long-term follow-up.

Researchers are evaluating an Internet-based pain coping skills program combined with enhanced usual care to see if it improves pain severity and pain interference among adult cancer survivors experiencing persistent cancer-related pain. The study also investigates how this program affects opioid and other pain medication use, quality of life, self-confidence in managing pain, and other factors such as fatigue, sleep, emotional distress, and cognitive function. The study plans to enroll 250 participants who have had invasive cancer treated with surgery, radiation, chemotherapy, or other therapies. Participants in the study will be randomly assigned to either receive the 8-session Internet-based pain management program along with enhanced usual care or receive enhanced usual care alone. The program is designed to help participants better manage their cancer-related pain through online sessions. Each participant will be involved for about 9 months, from the initial randomization to the final follow-up assessment at week 34. During the study, participants will complete assessments evaluating pain severity and pain interference using the Brief Pain Inventory. Researchers will also measure medication use, quality of life, pain management confidence, and other health factors through questionnaires and interviews. Participants are expected to complete follow-up assessments at 22 and 34 weeks. The study includes monitoring for safety and adherence to the pain management program, and those without reliable internet access may receive tablets to participate.

Researchers are investigating treatment options for men with unfavorable risk localized prostate cancer to determine if a shorter, higher-dose radiation therapy called Stereotactic Body Radiation Therapy (SBRT) is as effective as the usual external beam radiation therapy (EBRT) combined with a brachytherapy boost. This phase III randomized trial compares these approaches, both combined with androgen deprivation therapy (ADT), to improve cancer control and reduce recurrence. The study focuses on progression-free survival, measuring the time until biochemical failure, additional treatment, recurrence, progression, or death over 8.6 years. Participants receive one of two radiation treatments: the usual approach involves 46 Gy of EBRT in 23 sessions to the pelvis and prostate plus a low or high-dose brachytherapy boost, or 25 Gy of EBRT in 5 sessions combined with the same boost. The experimental group receives SBRT alone with 25 Gy to the pelvis and 40 Gy to the prostate in 5 sessions. ADT is given based on risk level, lasting 6 months for unfavorable intermediate risk or 24 months for high and very high risk. Treatments start within 12 weeks of enrollment. During the study, participants are monitored through regular assessments including quality of life questionnaires in English, French, or Spanish, and clinical follow-up to document treatment effects, adverse events, and cancer progression. The primary outcome is progression-free survival measured over approximately 8.6 years. Safety and treatment adherence are carefully tracked, and participants must be medically fit for brachytherapy and willing to comply with study procedures and follow-up.

Researchers are evaluating the addition of olaparib, a PARP inhibitor, as maintenance therapy following surgery and chemotherapy in patients with pancreatic cancer that has been surgically removed and who have a pathogenic mutation in BRCA1, BRCA2, or PALB2 genes. This phase II randomized, double-blind study aims to determine if olaparib can improve relapse-free survival compared to placebo in these patients, who have completed perioperative chemotherapy and have no evidence of recurrent disease. Participants are randomly assigned to receive either olaparib or a placebo orally twice daily in 28-day cycles for up to 12 cycles, as long as there is no disease progression or unacceptable side effects. Throughout the treatment period, patients undergo imaging tests such as CT scans or MRI and blood sample collections. After completing the treatment cycles, patients are followed up at 30 days, every 4 months for the first year, and then every 6 months for up to 10 years after randomization to monitor their health and disease status. During the study, researchers assess relapse-free survival by documenting any return of cancer or death from 22 to 44 months after randomization. They also collect blood samples and perform imaging tests to monitor the disease and evaluate treatment effects. Safety is carefully monitored, and patients must have recovered from previous treatments before starting the study. The study includes long-term follow-up to observe survival outcomes and any differences based on genetic mutations or prior chemotherapy regimens.

Researchers are evaluating the effects of cannabis and cannabinoid use on cancer-related symptoms in adults newly diagnosed with breast, colorectal, melanoma, non-Hodgkin lymphoma, or non-small cell lung cancer. This study focuses on patients who are planning to receive or have recently started systemic cancer treatments such as chemotherapy and immune checkpoint inhibitors (ICIs) targeting PD-1, PD-L1, or CTLA-4. The goal is to understand how cannabis use may be associated with symptom changes over time. Participants are enrolled in a non-interventional study where no experimental treatment is given. They complete surveys about their symptoms and cannabis use, and their medical records are reviewed regularly. The study tracks cancer-related symptoms monthly for up to 12 months after enrollment, allowing researchers to observe symptom patterns during ongoing cancer treatment. An optional substudy is available at select sites for patients with non-small cell lung cancer receiving paclitaxel and ICIs. During the study, participants complete online surveys in English or Spanish at their convenience, either at home or in clinic. Medical records are examined to gather information on treatments and health status. The main outcome measured is cancer-related symptoms, assessed monthly for one year. Safety monitoring includes ensuring participants have an expected life expectancy of at least six months and are not enrolled in hospice. The study aims to enroll 2000 patients across multiple sites in the United States.

Researchers are evaluating how to best recommend chemotherapy for patients with colon cancer after surgery by using the presence or absence of circulating tumor DNA (ctDNA) in the blood. This approach aims to identify microscopic residual tumor cells and may provide better risk prediction for cancer recurrence compared to traditional methods. The trial focuses on patients with Stage IIB, IIC, or III colon cancer who have undergone complete tumor removal. Participants will have their tumor tissue and blood tested centrally using the Signatera assay to determine ctDNA status. Patients without detectable ctDNA may avoid chemotherapy, while those with detectable ctDNA are considered at higher risk and will be randomly assigned to receive different chemotherapy regimens, including mFOLFOX6, CAPOX, or mFOLFIRINOX, given intravenously or orally over periods ranging from 3 to 6 months. The study includes initial screening, treatment, and possible second randomization for patients whose ctDNA status changes during monitoring. During the study, participants will undergo various assessments including blood tests, imaging scans, and performance evaluations to monitor their health and response to therapy. Researchers will track the time to ctDNA positivity and disease-free survival for up to 3 and 5 years, respectively. Safety and treatment effects will be closely observed throughout the study duration, ensuring thorough follow-up and monitoring for all participants.

Researchers are conducting a two-part, phase 2b/3 study to evaluate CSL300 (Clazakizumab) in adults with end stage kidney disease (ESKD) undergoing dialysis who have systemic inflammation and either atherosclerotic cardiovascular disease (ASCVD) or diabetes. The study aims to determine the best dose of CSL300 and assess its effects on cardiovascular outcomes and safety in this population. This multicenter, randomized, double-blind, placebo-controlled trial targets patients with elevated inflammation markers and significant health risks due to their conditions. In the first part (phase 2b), the study focuses on finding the appropriate dose of CSL300 compared to placebo. CSL300 is given through intravenous (IV) administration. The second part (phase 3) evaluates the impact of CSL300 on cardiovascular events such as heart attack or cardiovascular death over approximately 5 years, continuing to compare CSL300 to placebo for safety and efficacy. The placebo matches CSL300's excipient content but lacks the active drug. Participants will undergo baseline and regular assessments for inflammation markers like high-sensitivity C-reactive protein (hs-CRP) up to 12 weeks in phase 2b, and long-term monitoring for cardiovascular outcomes in phase 3. The study involves ongoing safety evaluations and efficacy measurements during the entire follow-up period. This comprehensive approach helps researchers understand how CSL300 affects inflammation and cardiovascular health in patients with ESKD on dialysis.

Researchers are comparing two approaches of standard therapy for patients with stage II to IIIB non-small cell lung cancer (NSCLC) that can be surgically removed. This phase III trial evaluates whether giving chemotherapy and immunotherapy before and after surgery (perioperative) is more effective than giving the same treatments only after surgery (adjuvant). The study aims to find out which method leads to better event-free survival and overall survival over several years. Participants are randomly assigned to one of two groups. In the adjuvant group, patients have surgery first, followed by up to four cycles of platinum-based chemotherapy and up to one year of immune checkpoint inhibitor treatment if there is no disease progression or unacceptable side effects. In the perioperative group, patients receive chemotherapy combined with immune checkpoint inhibitors before surgery, then have surgery, and continue immune checkpoint inhibitor therapy for up to one year afterward. Chemotherapy drugs used may include cisplatin, carboplatin, pemetrexed, gemcitabine, docetaxel, or vinorelbine, and immunotherapy drugs may include nivolumab, pembrolizumab, or atezolizumab. During the study, patients undergo imaging tests such as CT scans, MRI, or PET/CT scans to monitor their condition. After completing treatment, they are followed for up to 10 years with check-ups every six months. Researchers measure event-free survival at three years, overall survival up to 10 years, surgical outcomes, side effects, and other treatment-related factors to understand which approach offers better results for patients with resectable NSCLC.

Researchers are evaluating treatments for patients with metastatic kidney cancer to see if adding surgery to standard immunotherapy-based drug combinations improves outcomes. This phase III trial focuses on kidney cancer that has spread to other parts of the body. The study compares standard immunotherapy drugs, which help the immune system fight cancer, with or without the surgical removal of the kidney, known as nephrectomy. Doctors currently do not agree on whether surgery adds benefit when combined with these immunotherapy treatments. Participants first receive one of three immunotherapy-based drug regimens, including combinations of nivolumab, ipilimumab, pembrolizumab, avelumab, and axitinib, given through intravenous infusions and oral tablets over several weeks. After 10-14 weeks of this initial treatment, patients are randomly assigned to either continue immunotherapy drugs alone or to also have kidney surgery followed by the same drugs. Surgery may be done by different methods and must occur within 8 weeks of randomization. Axitinib is stopped at least 24 hours before surgery. During the study, participants undergo regular scans of the chest, abdomen, and pelvis to assess disease status. They are monitored for survival for up to 7 years after randomization, with follow-up visits every 3 months in the first year, then every 6 months for two years, and annually thereafter. Researchers also evaluate tumor response, surgical complications, and drug side effects. Specimens are collected for future research, and participants' health and treatment effects are closely followed throughout the study period.

Researchers are evaluating whether breast conservation surgery combined with endocrine therapy can achieve a similar rate of invasive or non-invasive ipsilateral breast tumor recurrence (IBTR) compared to breast conservation surgery followed by breast radiation and endocrine therapy in patients with Stage I, hormone sensitive, HER2-negative breast cancer with an Oncotype recurrence score of 18 or less. This Phase III trial builds on the established role of radiation after lumpectomy, aiming to identify if radiation can be safely omitted in certain low-risk patients to reduce treatment burden and side effects. Participants receive either breast radiation plus endocrine therapy or endocrine therapy alone. Radiation therapy involves external beam radiation to the whole breast with or without a boost, partial breast irradiation, or accelerated partial breast irradiation, starting within 12 weeks after the last breast surgery. Endocrine therapy is given for a minimum of 5 years, with the specific drug choice and schedule determined by the treating physician. Endocrine therapy may begin before, during, or after radiation therapy, depending on the treatment group. Throughout the study, participants undergo regular assessments including imaging such as mammograms or MRI within six months before enrollment, and clinical evaluations to monitor tumor recurrence. The main outcome measured is the time to invasive or non-invasive ipsilateral breast tumor recurrence over five years. Safety, adherence to therapy, and recovery from surgery are also monitored. The total participation period includes at least five years to evaluate long-term recurrence rates.
