Researchers are evaluating the real-world effectiveness, safety, and patient compliance of ribociclib combined with an aromatase inhibitor for adjuvant treatment in patients with hormone receptor-positive, HER2-negative early breast cancer at high risk of recurrence. This observational study also compares ribociclib treatment with abemaciclib plus endocrine therapy and endocrine therapy alone, aiming to better understand treatment decisions and clinical adoption in routine practice. The study is conducted across breast centers and gynecological practices to represent typical healthcare settings. Participants receive treatment based on their physicians clinical judgment without randomization or intervention assignment. The study collects data from patients treated with ribociclib plus aromatase inhibitor with or without luteinizing hormone-releasing hormone LHRH, abemaciclib plus endocrine therapy with or without LHRH, or endocrine therapy alone with or without LHRH. Baseline data and follow-up information on adverse events, quality of life, treatment adherence, and socio-economic factors are gathered over time. During the study, participants undergo assessments including evaluation of invasive disease-free survival up to 36 months, quality of life questionnaires, medication adherence reports, and monitoring of adverse events and treatment changes. Data on reasons for treatment decisions, patient perceptions, and healthcare provider involvement are also collected. The study duration extends up to 39 months to provide a comprehensive overview of treatment impact and patient experience in real-world clinical settings.

Researchers are evaluating elacestrant compared to standard endocrine therapies in adults with node-positive, Estrogen Receptor-positive ER, HER2-negative early breast cancer who are at high risk of cancer returning. The study focuses on those who have had prior endocrine therapy and aims to measure how well elacestrant may prevent invasive breast cancer recurrence over five years. Participants are randomly assigned to receive either 345 mg of elacestrant daily for five years or continue their prior standard endocrine therapy, which may include an aromatase inhibitor anastrozole, letrozole, or exemestane or tamoxifen. The trial is open-label, meaning both participants and researchers know which treatment is given. During the study, participants will have regular assessments to monitor cancer recurrence, survival, side effects, and quality of life. Evaluations include questionnaires on health status and physical functioning at baseline, six months, and annually for up to five years. Safety is tracked through adverse event reporting up to five years plus 28 days. The total participation duration can last up to five years with ongoing monitoring and data collection.

Researchers are evaluating the effects of the drug imlunestrant LY3484356 in premenopausal women with early estrogen receptor-positive ER, HER2-negative breast cancer. The study includes two groups one that explores imlunestrant alone or combined with ovarian suppression, and another that studies imlunestrant without ovarian suppression. The trial compares imlunestrants impact on breast cancer cells and ovarian function to tamoxifen, a known treatment. Participants in Cohort 1 will receive imlunestrant orally either alone or with goserelin a drug given by injection to suppress ovarian function for up to 29 days. Some in this group will take tamoxifen orally as a comparator. Cohort 2 participants will take imlunestrant or tamoxifen orally for up to 6 months without ovarian suppression. The study is open-label, randomized, and phase 2, designed to assess treatment effects in parallel groups. During the study, participants will provide tumor samples before and during treatment, and researchers will monitor changes in specific cancer markers like Ki-67, estrogen receptor ER, and progesterone receptor PR expression. They will also track the rate of ovarian cysts up to 180 days. Participants must attend scheduled visits for evaluations, including performance status checks and safety assessments. The trial is expected to continue until December 2029.

Researchers are evaluating the addition of Tersolisib LY4064809STX-478 to other anti-cancer drugs as a first treatment for adults with advanced hormone receptor-positive HRhuman epidermal growth factor receptor 2-negative HER2- breast cancer that has a PIK3CA mutation. This Phase 3 randomized, double-blind, placebo-controlled trial aims to understand the efficacy and safety of this combination compared to placebo, focusing on improving outcomes for patients with this specific genetic change. Participants receive LY4064809 orally in one of two doses combined with a CDK46 inhibitor such as Ribociclib, Palbociclib, or Abemaciclib and endocrine therapy ET administered orally or via intramuscular injection. The comparison group receives a placebo combined with the same CDK46 inhibitor and ET. The study includes two parts Part 1 explores dose optimization, and Part 2 evaluates the treatment combinations effectiveness and safety as a first-line therapy. During the study, participants will have regular assessments to monitor cancer response, progression, and safety over an estimated period of up to 5 years or more. Researchers will measure outcomes such as overall response rate, progression-free survival, duration of response, overall survival, and quality of life. Treatment continues as long as the cancer benefits without intolerable side effects. Safety monitoring, laboratory tests, and quality of life questionnaires are part of the participant involvement throughout the trial.

Researchers are evaluating the effectiveness and safety of inavolisib combined with Phesgo compared to a placebo combined with Phesgo as maintenance treatment for participants with previously untreated HER2-positive advanced breast cancer that has a PIK3CA mutation. This Phase 3 study focuses on participants with locally advanced or metastatic breast cancer who have completed induction therapy. Participants first receive induction therapy with Phesgo plus taxane-based chemotherapy. Following this, they enter the maintenance phase where they are randomly assigned to receive either inavolisib tablets taken orally once daily for 21 days of each 21-day cycle along with Phesgo administered subcutaneously every 3 weeks, or a matching placebo tablet with Phesgo on the same schedule. Optional endocrine therapy may be given based on the investigators choice according to standard care. Throughout the study, participants undergo regular monitoring including tumor assessments, quality of life questionnaires, and safety evaluations lasting up to approximately 111 months. Key outcomes measured include progression-free survival assessed by investigators, overall survival, response rates, duration of response, and adverse event rates. Plasma concentrations of inavolisib are also measured at specific timepoints. Participants will be followed closely during and after treatment to assess these outcomes over an extended period.

Researchers are studying metastatic colorectal carcinoma mCRC patients who have a specific BRAFV600E mutation, which is linked to poorer outcomes compared to those without it. This mutation leads to shorter survival times after initial treatments, prompting the need for new therapy combinations. This research aims to observe how the drugs encorafenib and cetuximab work together in real-world settings for patients who have already received prior systemic therapies. This non-interventional, prospective, longitudinal study focuses on patients treated with encorafenib plus cetuximab following prior systemic therapy. The study collects data on treatment effectiveness, safety, and quality of life among a broader patient population in Germany, Austria, and Switzerland. Patients may have started treatment up to three months before joining the study or plan to start soon, and the study observes their outcomes without influencing treatment decisions. Participants will be monitored through data collection on their disease and treatment profiles, including patient and physician assessments, adverse events, and treatment details. The main outcome measured is overall survival at 12 months after starting treatment. Additional information gathered includes treatment duration, dose intensity, interruptions, and patient-reported quality of life using questionnaires. Safety and tolerability are also evaluated throughout treatment, with follow-up averaging nine months.

Researchers are evaluating the combination of capivasertib with CDK46 inhibitors and fulvestrant in adults with hormone receptor-positive and HER2-negative locally advanced or metastatic breast cancer. This Phase IbIII study aims to determine the safe dose for the combination treatment in the initial Phase Ib part and then compare its effectiveness and safety to standard treatment in the Phase III part in participants who have not received prior endocrine therapy in the advanced setting. In the Phase Ib portion, participants receive capivasertib combined with one of the CDK46 inhibitorspalbociclib, ribociclib, or abemacicliband fulvestrant to establish recommended doses. In the Phase III part, participants are randomly assigned to receive either capivasertib plus fulvestrant with a chosen CDK46 inhibitor palbociclib or ribociclib or fulvestrant with a CDK46 inhibitor alone. Treatments are given in 28-day cycles with specific dosing schedules for each drug, including oral doses of capivasertib and CDK46 inhibitors and injections of fulvestrant. Participants undergo screening and regular monitoring throughout the study, including assessments of treatment side effects, tumor progression, and blood samples for pharmacokinetics and biomarker analysis. The primary outcomes include dose-limiting toxicities and adverse events in Phase Ib and progression-free survival in Phase III, with follow-up lasting up to several years to evaluate overall survival, response rates, physical functioning, and quality of life.

Researchers are investigating ribociclib combined with standard endocrine therapy for women with advanced hormone receptor-positive HR and HER2-negative breast cancer receiving first-line treatment. This phase IV, open-label study aims to understand how ribociclib works over time and identify patterns of resistance. The study also focuses on survival rates at 12 months and includes a comprehensive program to discover and validate biomarkers related to treatment outcomes. Participants will receive ribociclib once daily for 21 days followed by 7 days off, in 28-day cycles, alongside standard endocrine therapy prescribed by their doctors. The treatment follows the approved guidelines Summary of Product Characteristics for ribociclib. This trial plans to enroll 1000 female patients across 75 sites in Germany and involves extensive biomarker sampling from blood, tissue, and immune cells before, during, and after treatment or disease progression. During the study, participants will have regular assessments including survival monitoring at various time points up to 36 months, quality of life evaluations, and safety checks for treatment-related side effects. Samples for biomarker research will be collected to help understand treatment response. Follow-up includes collecting data on progression-free and overall survival, quality of life, and adverse events, with total study involvement lasting up to 36 months.

Researchers are evaluating elacestrant compared to standard endocrine therapy in patients with estrogen receptor-positive ER and human epidermal growth factor receptor 2-negative HER2- breast cancer who have a relapse detected by circulating tumor DNA ctDNA. This international, multi-center, randomized, open-label phase III trial focuses on patients without distant metastasis who show ctDNA positivity during screening. The study aims to assess whether elacestrant can improve outcomes over the current standard endocrine treatments. The study consists of two phases. First, during the ctDNA screening phase, patients on standard adjuvant endocrine therapy will have plasma samples collected every six months for about 5.7 years to detect ctDNA. Patients who test positive will undergo imaging to confirm no distant metastasis and then be randomized 11 to either continue their current endocrine therapy or receive elacestrant 400 mg orally once daily. Treatment duration depends on prior endocrine therapy length, lasting between 2 to 6 years. Intensive follow-up with ctDNA testing and imaging occurs for up to 3 years after randomization. Participants will be monitored closely with blood tests for ctDNA at weeks 4, 16, and every 16 weeks thereafter, along with yearly mammograms, bone scans, and CT scans every 16 weeks to detect metastases or recurrences. Safety, quality of life, and overall survival are assessed throughout, with follow-up continuing until three years after the last patient enrolls. The primary outcome measured is distant metastasis-free survival at 6.25 years after the first randomization.

Researchers are studying patients with hormone receptor-positive, HER2-negative locally advanced or metastatic breast cancer who have gBRCA12 mutations. This study aims to evaluate whether adding elacestrant, a new oral estrogen receptor blocker, to the standard olaparib treatment can improve progression-free survival compared to olaparib alone. This is a phase II, multi-center, randomized, open-label study with patients assigned in a 21 ratio to two different treatment groups. Participants randomized to Arm A will receive 600 mg of olaparib daily plus 400 mg of elacestrant daily, while those in Arm B will receive 600 mg of olaparib daily alone. Treatment will continue until disease progression, unacceptable side effects, patient withdrawal, or the study ends. Pre- and perimenopausal women, as well as men, will also receive a GnRH analogue at least two weeks before treatment starts. Dose modifications are provided for managing specific side effects. During the study, blood tests will be done at the start of each treatment cycle, and imaging scans along with quality of life assessments will be performed every three months or if disease progression is suspected. Researchers will measure progression-free survival, overall survival, treatment failure times, response rates, clinical benefit, adverse events, and treatment compliance. Participants may remain in the study for up to 48 months, with an average treatment duration of about 12 months per patient.
