Clinical, Laboratory and Epidemiologic Characterization of Individuals and Families at High Risk of Hematologic Cancer

Waldenstrom Macroglobulinemia Chronic Lymphocytic Leukemia Hodgkin Disease NonHodgkin Lymphoma +1

Background: * Individuals may be prone to develop blood or lymph node cancers (leukemia or lymphoma) for a variety of reasons, including genetic predisposition to these cancers, environmental exposures or other medical conditions. * Studies of people and families at high risk of cancer often lead to clues about their cause that may also be important regarding the sporadic occurrence of these cancers in the general population. * Identifying genetic or environmental factors that play a role in the development of these diseases may be important in developing prevention trials, screening programs and treatments. Objectives: * Describe the cancers and other conditions in families with blood or lymph node cancer. * Find and describe genes that may cause blood and lymph node cancer, and understand how they work in families. * Use laboratory methods to try to determine if it is possible to identify who is at highest risk of blood or lymph node cancer. * Test how genes act with other factors to alter the risk of disease, its severity or its manifestations in families. Eligibility: * Individuals of any age with a personal or family history of a blood or lymph node cancer. * Individuals with a personal or family history of medical conditions or environmental exposures that may predispose to blood or lymph node cancer. Design: * Participants complete questionnaires about their personal and family medical history and provide consent for researchers to review their medical records and pathology materials related to their care and those of deceased relatives with blood or lymph node cancer, tumors, or other related illnesses for whom they are the legally authorized representative. * Participants donate a sample of blood or cheek cells, or a lock of hair for genetic studies. * Patients may also be evaluated at the NIH Clinical Center by one or more of the following specialists: cancer doctor or blood specialist, medical geneticist, research nurses or clinical social worker. They may have blood and urine tests and a cheek swab or mouth wash to collect cheek cells. Some patients may also be asked to have x-rays and routine imaging, such as CT scans or ultrasound tests, cell surface markers, skin biopsy, and, with special consents, bone marrow biopsy, MRI or PET scans, apheresis or fluorescein angiography and photography.

Beamion LUNG-2: A Study to Test Whether Zongertinib (BI 1810631) Helps People With Advanced Non-small Cell Lung Cancer With HER2 Mutations Compared With Standard Treatment

Lung Cancer, Non-squamous, Non-small Cell

This study is open to adults 18 years and older with advanced or metastatic non-small cell lung cancer. People can join the study if they have tumours with HER2 mutations and have not yet received any systemic therapy including chemotherapy for advanced or metastatic lung cancer. The purpose of this study is to find out whether a medicine called zongertinib (BI 1810631) can slow down the worsening of advanced non-small cell lung cancer better than the standard treatment available. Zongertinib may slow cancer cell growth by inhibiting HER2. This would prolong cancer re-occurrence and increase survival. Current standard treatment is pembrolizumab plus platinum-pemetrexed chemotherapy. Participants are put into 2 groups by chance. One group receives zongertinib at regular times throughout the study and the other group receives infusions of pembrolizumab, pemetrexed and cisplatin or carboplatin (pembrolizumab plus platinum-pemetrexed chemotherapy) into a vein. Participants may be in the study up to a maximum of 70 months. During this time, they visit the study site about every 3 weeks for study procedures. The doctors regularly check the size of the tumour with a CT or MRI scan, at the beginning of the study and every 6 weeks. After 18 months they check the tumour size every 12 weeks. Doctors regularly check whether the cancer has spread to other parts of the body. The doctors also regularly check participants' health and take note of any unwanted effects. The time it takes for the cancer to worsen is compared between the 2 groups to see whether the treatment works. The participants also fill in questionnaires about their symptoms and quality of life.

Serplulimab Combined With Chemotherapy in Patients With Resectable Non-small-cell Lung Cancer

NSCLC Neoadjuvant Therapy

China with high incidence of non-small cell lung cancer. In the past few decades, surgery, radiotherapy, chemotherapy and other treatments were continuously improved, however, the mortality of lung cancer patients was not significantly decreased. For patients with locally advanced lung cancer, direct surgery is not effective. It is difficult to achieve radical resection by surgery merely, and even if many patients receive surgery, they may eventually have tumor recurrence and poor survival rate. Therefore, it is necessary to explore effective perioperative neoadjuvant treatment to reduce the risk of postoperative recurrence and improve the postoperative survival rate of patients. According to the reports, PD-1/ PD-L1 immunocheckpoint inhibitor may become a new method for the treatment of lung cancer. Preliminary clinical results showed that immunotherapy combined with chemoradiotherapy provided a synergies antitumor effect. Multiple clinical results showed that serplulimab provided higher overall response rate for advanced lung cancer. However, in patients with locally advanced lung cancer, the efficacy of serplulimab combined with chemotherapy for sequential radical surgery is still unclear. The purpose of this study is to observe and evaluate the efficacy and safety of serplulimab combined with chemotherapy in the neoadjuvant therapy of resectable non-small cell lung cancer.

POTENT - Tepotinib in Combination With Pembrolizumab in NSCLC

Advanced Cancer Non Small Cell Lung Cancer

This clinical study is looking at the combination of two experimental drugs called tepotinib and pembrolizumab. Pembrolizumab, also known as Keytruda, is licenced and available by prescription to treat a variety of cancers. Tepotinib is currently licensed in the UK for use in non-small cell lung cancer (NCSLC) and is being investigated for this purpose. Cancer immunotherapy drugs hold great promise but still do not work for many patients. Laboratory studies on cancers that do not respond well to immunotherapy reveal that most of these tumours do not have any immune cells. This suggests that the cancer has successfully hidden itself and avoided being recognised by the immune system. This study aims to use a novel approach using a targeted drug, tepotinib, to target the gene involved with NSCLC. Tepotinib is a type of drug called a kinase inhibitor. Kinase inhibitors are a newer type of drug being used to try to treat cancers. They act by blocking some of the chemical messengers that are part of the signalling process within cancer cells that control their growth. Tepotinib is used in adults to treat NSCLC that can have certain abnormal changes in the mesenchymal-epithelial transition factor gene (MET) and which has spread and/or cannot be removed by surgery. The changes in the MET gene can make an abnormal protein which can lead to uncontrolled cell growth and cancer. By blocking this abnormal protein, tepotinib may slow or stop the cancer from growing as well as potentially shrinking the cancer. This study will include patients with and without the MET exon 14 mutations. In this clinical study, the investigators aim to test our ideas in a small number of people for the first time, specifically in those patients with cancers which do not respond to cancer immunotherapy.

A Study to Compare Early Use of Vinorelbine and Maintenance Therapy for Patients With High Risk Rhabdomyosarcoma

Alveolar Rhabdomyosarcoma Botryoid-Type Embryonal Rhabdomyosarcoma Embryonal Rhabdomyosarcoma Metastatic Embryonal Rhabdomyosarcoma +4

This phase III trial compares the safety and effect of adding vinorelbine to vincristine, dactinomycin, and cyclophosphamide (VAC) for the treatment of patients with high risk rhabdomyosarcoma (RMS). High risk refers to cancer that is likely to recur (come back) after treatment or spread to other parts of the body. This study will also examine if adding maintenance therapy after VAC therapy, with or without vinorelbine, will help get rid of the cancer and/or lower the chance that the cancer comes back. Vinorelbine and vincristine are in a class of medications called vinca alkaloids. They work by stopping cancer cells from growing and dividing and may kill them. Dactinomycin is a type of antibiotic that is only used in cancer chemotherapy. It works by damaging the cell's deoxyribonucleic acid (DNA) and may kill cancer cells. Cyclophosphamide is in a class of medications called alkylating agents. It works by damaging the cell's DNA and may kill cancer cells. It may also lower the body's immune response. Vinorelbine, vincristine, dactinomycin and cyclophosphamide are chemotherapy medications that work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. This trial may have the potential to eliminate rhabdomyosarcoma for a long time or for the rest of patient's life.

A Longitudinal Assessment of Frailty in Young Adult Survivors of Childhood Cancer

Acute Lymphoblastic Leukemia Brain Tumor Hodgkin Lymphoma

Advances in cancer therapies have led to increasing numbers of adult survivors of pediatric malignancy. Unfortunately, treatment of childhood cancer continues to require agents designed to destroy malignant cell lines, and normal tissue is not always spared. While early treatment- related organ specific toxicities are not always apparent, many childhood cancer survivors report symptoms that interfere with daily life, including exercise induced shortness of breath, fatigue and reduced capacity to participate in physical activity. These symptoms may be a hallmark of premature aging, or frailty. Frailty is a phenotype most commonly described in older adults; it indicates persons who are highly vulnerable to adverse health outcomes. Frailty may help explain why nearly two thirds of childhood cancer survivors have at least one severe chronic health condition 30 years from diagnosis, why childhood cancer survivors are more likely than peers to be hospitalized for non-obstetrical reasons, and why they have mortality rates more than eight times higher than age-and-gender matched members of the general population. Frailty is a valuable construct because it can be distinguished from disability and co-morbidity, and is designed to capture pre-clinical states of physiologic vulnerability that identify individuals most at risk for adverse health outcomes. These investigators have recently presented data indicating that impaired fitness is present in survivors of childhood acute lymphoblastic leukemia, brain tumor and Hodgkin lymphoma. This is relevant because frailty, characterized by a cluster of five measurements of physical fitness, is predictive of chronic disease onset, frequent hospitalization, and eventually mortality in both the elderly and in persons with chronic conditions. Using a frailty phenotype as an early predictor of later chronic disease onset will allow identification of childhood and adolescent cancer survivors at greatest risk for adverse health. An early indicator of those at risk for adverse health will allow researchers to test, and clinicians to provide, specific interventions designed to remediate functional loss, and prevent or delay onset of chronic health conditions. The investigators goals include characterizing physical frailty over a five year time span in a population of young adult survivors of childhood cancer, as well as assessing the association between frailty and the increase in the number and severity of chronic health conditions.

Yoga to Improve Disparities in Cancer Survivorship

Survivorship Cancer

This clinical trial tests the impact of a racially concordant trainer led yoga program on quality of life and symptom burden in Black and/or African American cancer survivors. Black individuals in the United States are more affected by cancer, despite modern advances. Cancer treatments can impact physical and mental health and overall quality of life and Black individuals report worse physical function and quality of life and less access to culturally appropriate support services. Yoga has been shown to have a positive impact on cancer and cancer treatment related symptoms and quality of life, however, a one size fits all approach has not been shown to be effective in diverse populations. A trainer that shares the same racial or ethnic background as the participant (racially concordant) may have a positive impact on communication, trust, and may improve accessibility and participation. Participating in a yoga program led by a racially concordant trainer may improve quality of life and symptom burden in Black and/or African American cancer survivors.

Mindfulness Intervention for Improving Nutrition in the Digital Kitchen Among Stage I-III Breast Cancer Survivors, MIND Trial

Anatomic Stage I Breast Cancer AJCC v8 Anatomic Stage II Breast Cancer AJCC v8 Anatomic Stage III Breast Cancer AJCC v8

This trial tests how well a remotely-delivered nutrition and culinary intervention works to improve diet quality among stage I-III breast cancer survivors. Despite the strong evidence demonstrating the benefits of healthy nutrition on improving cancer outcomes, most breast cancer survivors, do not meet the nutrition recommendations The use of technology in behavioral interventions is proving to be a cost-effective mode of delivering lifestyle education to promote behavior change. The Mindfulness Intervention for Nutrition in the Digital Kitchen (MIND) program is delivered through a learning management system on the Cook for Your Life platform (cookforyourlife.org). The Cook for Your Life platform is a cancer patient-facing interactive program offering free nutrition and healthy cooking information, recipes, and cooking videos that disseminate evidence-based information on nutrition and cancer survivorship. The MIND program may help improve diet quality and increase fruit and vegetable intake among stage I-III breast cancer survivors.

Testing Immunotherapy (Atezolizumab) With or Without Chemotherapy in Locoregional MSI-H/dMMR Gastric and Gastroesophageal Junction (GEJ) Cancer

Clinical Stage I Gastric Cancer AJCC v8 Clinical Stage I Gastroesophageal Junction Adenocarcinoma AJCC v8 Clinical Stage II Gastric Cancer AJCC v8 Clinical Stage II Gastroesophageal Junction Adenocarcinoma AJCC v8 +6

This phase II trial compares atezolizumab in combination with chemotherapy (docetaxel, oxaliplatin, leucovorin calcium, fluorouracil, capecitabine) to atezolizumab alone for controlling the growth and/or spreading of the disease in patients with gastric or gastroesophageal junction (JEG) cancer that has not spread from where it first started (local) or only has spread to nearby lymph nodes or tissue (locoregional) and has high microsatellite instability (MSI-H) and mismatch repair deficiency (dMMR). The mismatch repair (MMR) system in the body corrects errors made during the copying of DNA and serves as a proofreading function. If this system isn't working correctly, mutations (changes) in DNA occur which can allow the cancer to grow or spread. This is called dMMR (deficient mismatch repair) . MSI-H describes cancer cells that have a high number of mutations within microsatellites. For example, microsatellite testing that shows mutations in 30% or more microsatellites is called microsatellite instability-high (MSI-H). Microsatellites are short, repeated sequences of DNA. There is evidence that MSI-H/ dMMR gastric or GEJ tumors respond well to immunotherapy. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Docetaxel is in a class of medications called taxanes. It stops tumor cells from growing and dividing and may kill them. Oxaliplatin is in a class of medications called platinum-containing antineoplastic agents. It damages the cell's DNA and may kill tumor cells. Capecitabine is in a class of medications called antimetabolites. It is taken up by tumor cells and breaks down into fluorouracil, a substance that kills tumor cells. Chemotherapy drugs such as leucovorin calcium and fluorouracil work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Using atezolizumab as immunotherapy with and following chemotherapy versus atezolizumab alone prior to and after surgery may shrink or stabilize the tumor in patients with MSI-H/dMMR localized gastric or GEJ cancer and may increase the length of time after treatment that cancer does not come back or get worse.

Study to Assess Adverse Events and Change in Disease Activity in Adult Participants With Select Advanced Solid Tumor Indications Receiving Intravenous (IV) ABBV-400

Hepatocellular Carcinoma Pancreatic Ductal Adenocarcinoma Biliary Tract Cancers Esophageal Squamous Cell Carcinoma +4

Cancer is a condition where cells in a specific part of body grow and reproduce uncontrollably. The purpose of this study is to assess adverse events and change in disease activity when ABBV-400 is given to adult participants to treat advanced solid tumors. ABBV-400 is an investigational drug being developed for the treatment of advanced solid tumors. Study doctors put the participants in groups called cohorts. Cohorts 1-8 receive ABBV-400 alone (monotherapy) followed by a safety follow-up period. Cohort 9 receives ABBV-400 in combination with a strong CYP3A3 inhibitor (ITZ) followed by a safety follow-up period. Approximately 285 adult participants with hepatocellular carcinoma (HCC), pancreatic ductal adenocarcinoma (PDAC), biliary tract cancers (BTC), esophageal squamous cell carcinoma (ESCC), triple negative breast cancer (TNBC), hormone receptor+/human epidermal growth factor receptor 2 negative (HER2-) breast cancer (hormone receptor-positive \[HR+\]/HER2-breast cancer \[BC\]), head and neck squamous-cell-carcinoma (HNSCC), Platinum Resistant High Grade Epithelial Ovarian Cancer (PROC)/primary peritoneal/fallopian tube cancer, or advanced solid tumors, will be enrolled in the study in approximately 54 sites worldwide. In cohorts 1-8, participants with the following advanced solid tumor indications: HCC, PDAC, BTC, ESCC, TNBC, HR+/HER2-BC, HNSCC, and PROC/primary peritoneal/fallopian tube cancer will receive intravenous (IV) ABBV-400 monotherapy and in cohort 9 participants will receive intravenous (IV) ABBV-400 and an oral solution of ITZ, for up to 3 years during and up to the treatment period with an additional safety follow-up period of up to 2 years. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at an approved institution (hospital or clinic). The effect of the treatment will be frequently checked by medical assessments, blood tests, questionnaires and side effects.

Integrated Genomic Prostate Score With MRI Targeted Prostate Biopsies

Prostate Cancer

Background: Prostate cancer is one of the most common cancers in men. For some men, their cancer is monitored. Others have surgery to remove the prostate. Focal therapy is another treatment option. It treats the areas of cancer selectively, which leaves the rest of the prostate intact. This can help lessen side effects. Men who get focal therapy must be chosen carefully. The Oncotype DX Genomic Prostate Score (GPS) assay tests biopsy samples for certain cancer-related genes. It then then gives a score from 1 to 100 to predict the likelihood of poor outcomes. The GPS is used to choose men for focal therapy. Researchers want to test the GPS further. Objective: To assess how GPS may be useful when used with MRI to improve how men are chosen for focal therapy of prostate cancer. Eligibility: Men age 18 and older who had NCCN low or intermediate risk prostate cancer and had MRI and radical prostatectomy at the Urologic Oncology Branch, National Cancer Institute and collaborating centers. Design: This is a multisite study. It will review data and samples that were collected in the past. Samples and images from up to 277 participants will be used. Tumor tissue will be tested with the GPS. Data such as age at diagnosis, race, biopsy results, and pathology results will be merged with the GPS results. Data will be entered into an in-house electronic system. It will be password protected. All data will be kept in secure sites that comply with NIH security standards.

Patient-Reported Outcome Version of the Common Criteria for Adverse Events

Survivorship Cancer

Childhood cancer survivors are vulnerable to treatment-related late effects, including physical and psychosocial morbidities, subsequent malignancies, and premature death. Symptom assessment provides a unique insight into survivorship care since symptoms not only indicate the manifestation for the occurrence of chronic health conditions, but also impact quality of life and survival. The National Cancer Institute (NCI) has developed a Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE) to assess symptomatic adverse events (AEs) for adult-onset cancer patients who are receiving cancer therapies. However, content-appropriate and clinically validated symptom assessment tools for adult survivors of childhood cancer are not available. Primary Object 1: Establish content validity for the PRO-CTCAE-SCC Primary Objective 1A: Conduct a symptom selection process through qualitative research to identify symptomatic AEs for adult survivors of childhood cancer Primary Objective 1B: Create symptomatic AE items for adult survivors of childhood cancer based on the prevalence and clinical importance ratings on the items Primary Objective 2: Validate the PRO-CTCAE-SCC using psychometric methods and objective clinical parameters Primary Objective 2A: Test dimensionality for the PRO-CTCAE-SCC Primary Objective 2B: Test clinical validity for the PRO-CTCAE-SCC Primary Objective 2C: Test responsiveness to change for the PRO-CTCAE-SCC Secondary Objective 1: Increase clinical usefulness of the PRO-CTCAE-SCC Secondary Objective 2: Establish meaningful cut-points and minimally important differences (MIDs) on symptom burden scores for clinical decision-making

Proton Therapy vs. IMRT for Low or Intermediate Risk Prostate Cancer

Prostate Cancer

We are studying whether men being treated for prostate cancer have the same amount of side effects from either one of two different external radiation treatments: IMRT or PBT. With IMRT, a number of x-ray beams are used to shape the radiation to the prostate. PBT is another type of external radiation treatment for prostate cancer that is used in a few centers in the United States. Protons are tiny particles with positive charge that can be controlled to travel a certain distance and stop. PBT is precise like IMRT, but it uses proton beams instead of x-ray beams. IMRT and PBT aim to deliver most of the radiation to the prostate cancer while sparing surrounding tissues. Both IMRT and PBT have been used in the treatment of prostate cancer and are thought to be equally effective at curing prostate cancer. However, both treatments have also been shown to cause the potential side effects of radiation, including bowel, urinary and erectile problems. It is possible that side effect rates with PBT will be lower, the same, or even higher than with IMRT, but this has not been studied well to date. Though both of these radiation therapies have been used in the past to treat prostate cancer, there has never been a study that compares the effects of these two therapies to see which one has less side effects. In this research study, we are comparing IMRT to PBT to determine which therapy best minimizes the side effects of treatment.

Agriculture Health Study

Prostate Cancer Pesticide Exposures Lymphoma Multiple Myeloma

The "Agricultural Health Study" (AHS) is a collaborative effort between the National Cancer Institute and the National Institute of Environmental Health Sciences. The U.S. Environmental Protection Agency and the National Institute for Occupational Safety and Health are providing support for a limited exposure assessment effort. Initial data collection on a prospective cohort of 89,658 study subjects has been completed as of December 1997. Participants completed questionnaires that included items on pesticides used, other agricultural exposures, and work practices that modify exposure as well as on other activities that may affect either exposure or disease risks (e.g., diet, exercise, alcohol consumption, medical conditions, family history of cancer, other occupations and smoking history). Phase II of the study (1998-2003) updated information on occupational exposures, diet, work practices and medical history by means of a computer assisted telephone interview. We also collected buccal cells on sample of 34,000 study participants to assess the effect of inheritable polymorphisms and the interaction of environment and genomic predisposition. The stimulus for this prospective investigation comes from the growing evidence that, despite a low mortality overall, farmers experience an excess of several cancers. These excesses have been observed in retrospective epidemiological studies among agricultural workers in several countries. Excess cancers are observed for the lymphatic and hematopoietic system, connective tissue, skin, brain, prostate, stomach and lips. Several of these tumors (brain, NHL, multiple myeloma, and prostate) are also increasing in the general population in many of these countries. This suggests a common set of exposures may explain the high rates in farmers and rising rates in the general population. Farmers, their families, and other pest control workers may have contact with a variety of potentially hazardous substances including pesticides, solvents, fuels and oils, engine exhaust, dust and zoonotic viruses and other microbes. Our cohort study includes all registered pesticide applicators in Iowa and North Carolina and the spouse of applicators who are farmers. The health effects of pesticide use are the primary focus of the study. The influence of other farm exposures are also being evaluated. The focus of the phase II follow-up period (2004-2008) is to update exposure information and health histories by means of a computer assisted interview and also following the cohort to determine disease incidence and mortality. The cohort is being followed through the cancer registries within Iowa and North Carolina, the Social Security Administration database, state vital statistics offices, National Death Index, and various in-state databases, such as the listing of registered pesticide applicators. Individuals who enrolled into the study but who are no longer at the address given during enrollment (based on subsequent attempts at follow up) have been submitted and will continue to be submitted (through NIOSH) in the standard format to the IRS under their Project 057 Taxpayer Address Request Program. Identifying data provided to the IRS include only SSN and the first four letters of last name of cohort member. IRS provides in return the most current address in IRS records if a match (SSN + all four letter of last name) is found. The purpose of this effort is to identify members of the cohort who have moved out of state, to enable adjustment of person-years for incidence and mortality calculations. Persons who have moved out of state can be followed for vital status and cause of death, but not for cancer incidence. Continuation of the protocol will provide a valuable epidemiologic resource to help prevent cancers in the future by identifying risk factors in the rural/agricultural environment. Because more cases of important cancer outcomes occur in this cohort every year, potential cancer causes can be evaluated with increased statistical power. Larger number of cases also allows for statistical control of confounding factors, making more meaningful conclusions about cancer risk, and, for some relatively infrequent cancers, such as the lyphomas and leukemias, greater follow-up time is necessary to make any meaningful observations.

Responding to Late Effects in Survivors of Childhood Cancer

Survivorship Model of Care Support

Survivors of childhood cancer need ongoing support to navigate their needs after cancer treatment. Using technology may offer us new ways to collect and share information about cancer survivorship follow-up with young survivors, their carers, and primary care providers. Through the support of the Kids Cancer Project, in Phase 1 of this study, will co-design an electronic survivorship 'portal' that links young survivors with their cancer treatment information, and health care teams. In later Phases we will implement and evaluate the survivorship portal.

A Study to Learn About the Study Medicine Called PF-07220060 in Combination With Fulvestrant in People With HR-positive, HER2-negative Advanced or Metastatic Breast Cancer Who Progressed After a Prior Line of Treatment

Advanced or Metastatic Breast Cancer

The purpose of this study is to learn about the safety and how effective the study medicine (PF-07220060) plus fulvestrant is compared to the study doctor's choice of treatment in people with advanced or metastatic breast cancer. Advanced cancer is the one that is unlikely to be cured or taken care of with treatment. Metastatic cancer is the one that has spread to other parts of the body. This study is seeking female and male participants who: * are 18 years of age or older; * are hormone receptor (HR)-positive and human epidermal growth factor receptor 2 (HER2)-negative; * have advanced or metastatic breast cancer after taking other treatments before this study; * have not taken or need to take medications that are not allowed by the study protocol; * do not have any medical or mental conditions that may increase the risk of study participation. Half of the participants will take PF-07220060 two times daily by mouth along with fulvestrant. Fulvestrant will be given as a shot into the muscle. The other half will take the study doctor's choice of treatment which can either be: * Fulvestrant alone taken as shot into the muscle. * Everolimus along with exemestane taken once daily by mouth. This study will compare the experiences of participants receiving the study medicine plus fulvestrant to those who are receiving the study doctor's choice of treatment. This will help decide if the study medicine is safe and effective. Participants will receive study treatment and/or will be in the study until: * imaging scans (such as an MRI and/or CT) show that their cancer is getting worse. * the study doctor thinks the participant is no longer benefitting from the study medicine. * has side effects that become too severe. A side effect is a reaction (expected or unexpected) to a medicine or treatment you take. * the participant chooses to stop taking part.
