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 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 investigating whether adding the drug Docetaxel to the usual hormone treatments, Androgen Deprivation Therapy ADT and Androgen-Receptor Pathway Inhibitor ARPI, can better control metastatic castration sensitive prostate cancer in men who have not responded optimally to initial hormone therapy. This phase III, international, open-label, randomized trial seeks to compare the effectiveness of this combined approach against the standard hormone therapy alone. Participants will be randomly assigned to receive either the standard hormone therapy with ADT plus ARPI or the same hormone therapy combined with Docetaxel chemotherapy. The trial focuses on men with metastatic prostate cancer who continue to have elevated PSA levels after 6 to 12 months of hormone-targeting treatment. Treatments are administered according to physician choice and assignment, and the study evaluates outcomes over a long period. During the trial, participants will be closely monitored with assessments including PSA levels and clinical progression over 39 months. Researchers will measure overall survival as the primary outcome, along with secondary outcomes such as PSA progression, PSA response, PSA kinetics, and progression-free survival. Participants must be accessible for treatment and follow-up to allow for complete documentation of treatment effects and adverse events throughout the study duration.

Researchers are studying premenopausal women with early-stage breast cancer that is estrogen receptor-positive and HER2-negative, focusing on tumors with specific gene recurrence scores. The trial aims to find out if adding chemotherapy to ovarian function suppression plus endocrine therapy improves invasive breast cancer-free survival compared to ovarian function suppression plus endocrine therapy alone. This Phase III trial addresses the need for better treatments in younger women, given their higher risk and past conflicting study results on ovarian suppression and chemotherapy. Participants are randomly assigned to one of two groups one receiving ovarian function suppression combined with an aromatase inhibitor for five years, and the other receiving adjuvant chemotherapy followed by the same ovarian function suppression and aromatase inhibitor regimen. Choices for the aromatase inhibitor and gonadotropin releasing hormone agonist are made by the investigator, with options including drugs such as goserelin, leuprolide, or triptorelin. Endocrine treatment beyond five years is at the investigators discretion, and bilateral oophorectomy may be used instead of ovarian suppression if preferred. During the study, participants are monitored over 11 years from randomization, with measurements including invasive breast cancer-free survival as the primary outcome. Secondary outcomes include disease-free survival, overall survival, recurrence intervals, menopausal symptoms, and pain during aromatase inhibitor therapy. Safety and treatment effects are assessed through regular evaluations, and participants continue to be followed long term to understand the impact of treatments on their breast cancer outcomes.

Researchers are evaluating Izalontamab Brengitecan compared to platinum-based chemotherapy for patients with metastatic urothelial cancer that has progressed after immunotherapy. This Phase 23 randomized trial aims to find the best dose and assess progression-free survival and overall survival over up to five years. Participants must have confirmed advanced urothelial carcinoma and have experience with Anti-PD-L1 therapy. Participants will be assigned to receive either Izalontamab Brengitecan or platinum-based chemotherapy such as Cisplatin, Gemcitabine, or Carboplatin at specified doses on defined days. The study includes several arms and evaluates treatment effects in parallel groups. The Phase 2 portion focuses on determining the recommended Phase 3 dose, while Phase 3 assesses efficacy outcomes over several years. Throughout the trial, participants will undergo regular assessments including tumor measurement by RECIST v1.1, performance status evaluations, antibody-drug conjugate concentrations, and quality of life measurements. Outcome measures include progression-free survival, overall survival, objective response, duration of response, and time to response. The study involves long-term follow-up lasting up to five years to monitor treatment effects and safety.

Researchers are investigating treatments for men with prostate cancer that has returned after surgery, focusing on those who experience a rise in prostate-specific antigen PSA levels, indicating biochemical recurrence. The study examines whether adding enhanced systemic therapy apalutamide combined with abiraterone and prednisone to standard care, which includes prostate radiation therapy and short-term androgen deprivation, improves outcomes. Additionally, for patients whose cancer has spread beyond the pelvis as detected by PET imaging, the study evaluates the benefit of adding metastasis-directed radiation therapy. Participants undergo baseline PETCT or PETMR scans to determine the extent of cancer spread. Based on these results, they are randomized into one of four treatment arms standard radiation with androgen deprivation, enhanced therapy including apalutamide, or enhanced therapy plus targeted radiation for metastatic disease. Treatments involve various forms of radiation therapy, androgen deprivation drugs, and oral apalutamide, administered over six months in the absence of disease progression or unacceptable side effects. Some patients may receive repeat PET scans to assess treatment response. During the study, participants have scheduled assessments including imaging, blood tests measuring PSA levels, and quality-of-life questionnaires over up to ten years. Follow-up visits occur every three months for the first two years, then less frequently up to ten years. Researchers monitor progression-free survival, overall survival, event-free survival, PSA progression, adverse events, and quality of life measures including cognitive function and fatigue. This long-term monitoring aims to determine the effectiveness of the added therapies compared to standard treatment alone.
