A Study to Evaluate Adverse Events and Change in Disease Activity of Subcutaneous (SC) Epcoritamab in Combination With Oral and Intravenous Anti-Neoplastic Agents in Adult Participants With Non-Hodgkin Lymphoma
Description

B-cell Lymphoma is an aggressive and rare cancer of a type of immune cell (a white blood cell responsible for fighting infections). The purpose of this study is to assess the safety and tolerability of epcoritamab in combination with anti-neoplastic agents in adult participants with Non-Hodgkin lymphoma (NHL). Adverse events and change in disease activity will be assessed. Epcoritamab is an investigational drug being developed for the treatment of NHL. Study doctors put the participants in groups called treatment arms. The combination of epcoritamab with anti-neoplastic agents will be explored. Each treatment arm receives a different treatment combination depending on eligibility. Approximately 565 adult participants with NHL will be enrolled in 100 sites globally. In both the dose escalation and dose expansion arms participants will receive subcutaneous (SC) epcoritamab in 28 day, 21 day, or 56 day cycles dependent on the arm in combination with the anti-neoplastic agents described below: 1: Oral lenalidomide in participants (PPTS) with relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL); 2: Oral ibrutinib and oral lenalidomide in PPTS with with R/R DLBCL; 3: Intravenous (IV) polatuzumab vedotin, IV rituximab, IV cyclophosphamide, IV doxorubicin hydrochloride (HCl), and oral prednisone (pola-R-CHP) in PPTS with newly diagnosed treatment-naïve DLBCL; 4: Oral CC-99282 in PPTS with R/R DLBCL; 5: Oral CC-99282 in PPTS with R/R follicular lymphoma (FL); 6A: Oral ibrutinib in PPTS with R/R mantle cell lymphoma (MCL); 6B: Oral ibrutinib, and oral venetoclax in PPTS with R/R MCL; 7: Oral ibrutinib, and oral venetoclax in PPTS with newly diagnosed treatment-naïve MCL. 8: Oral pirtobrutinib in PPTS with R/R MCL.

Rapid Analysis and Response Evaluation of Combination Anti-Neoplastic Agents in Rare Tumors (RARE CANCER) Trial: RARE 1 Nilotinib and Paclitaxel
Description

Background: People with rare cancers often have limited treatment options. The biology of rare cancers is not well understood. Researchers want to find better treatments for these cancers. They want to test 2 drugs that, taken separately, have helped people with non-rare cancers. They want to see if these drugs together can make rare cancers shrink or stop growing. Objective: To learn if nilotinib and paclitaxel will benefit people with rare cancers. Eligibility: People age 18 and older who have a rare, advanced cancer that has progressed after receiving standard treatment, or for which no effective therapy exists. Design: Participants will be screened with medical history and physical exam. They will have blood and urine tests. They will have a pregnancy test if needed. They will have an electrocardiogram to check their heart. They will have imaging scans to measure their tumors. Participants will repeat the screening tests during the study. Participants will receive nilotinib and paclitaxel. The drugs are given in 28-day cycles. Nilotinib is a capsule taken by mouth twice a day. Paclitaxel will be given intravenously by peripheral line or central line once a week for the first 3 weeks of each cycle. Participants will keep a medicine diary. They will track when they take the study drugs and any side effects they may have. Participants may have optional tumor biopsies. Participants can stay on the study until their disease gets worse or they have intolerable side effects. Participants will have a follow-up phone call about 30 days after taking the last dose of study drugs.

ATHN Transcends: A Natural History Study of Non-Neoplastic Hematologic Disorders
Description

In parallel with the growth of American Thrombosis and Hemostasis Network's (ATHN) clinical studies, the number of new therapies for all congenital and acquired hematologic conditions, not just those for bleeding and clotting disorders, is increasing significantly. Some of the recently FDA-approved therapies for congenital and acquired hematologic conditions have yet to demonstrate long-term safety and effectiveness beyond the pivotal trials that led to their approval. In addition, results from well-controlled, pivotal studies often cannot be replicated once a therapy has been approved for general use.(1,2,3,4) In 2019 alone, the United States Food and Drug Administration (FDA) has issued approvals for twenty-four new therapies for congenital and acquired hematologic conditions.(5) In addition, almost 10,000 new studies for hematologic diseases are currently registered on www.clinicaltrials.gov.(6) With this increase in potential new therapies on the horizon, it is imperative that clinicians and clinical researchers in the field of non-neoplastic hematology have a uniform, secure, unbiased, and enduring method to collect long-term safety and efficacy data. ATHN Transcends is a cohort study to determine the safety, effectiveness, and practice of therapies used in the treatment of participants with congenital or acquired non-neoplastic blood disorders and connective tissue disorders with bleeding tendency. The study consists of 7 cohorts with additional study "arms" and "modules" branching off from the cohorts. The overarching objective of this longitudinal, observational study is to characterize the safety, effectiveness and practice of treatments for all people with congenital and acquired hematologic disorders in the US. As emphasized in a recently published review, accurate, uniform and quality national data collection is critical in clinical research, particularly for longitudinal cohort studies covering a lifetime of biologic risk.(7)

Utility of Plasma Circulating Tumor DNA (ctDNA) in Asymptomatic Subjects for the Detection of Neoplastic Disease
Description

Pathway Genomics Corporation (Pathway Genomics), a San Diego, California company, is involved in the development and validation of new molecular diagnostic assays for the analysis of circulating tumor deoxyribonucleic acid (DNA) (ctDNA) found in the plasma-derived DNA (cell-free DNA or cfDNA) in order to identify specific variants (mutations) in cancer driver genes. The purpose of testing for mutations in ctDNA is to detect and monitor cancer. All cells shed DNA into the bloodstream. Finding cancer-associated mutations in the cfDNA may lead to early detection of cancer in an otherwise apparently healthy (i.e. asymptomatic) individual or may allow the healthcare provider to more effectively monitor and treat a known cancer patient. The analysis is performed using a polymerase chain reaction (PCR)-based methodology where oligonucleotides are designed to target specific mutations in designated genes of interest followed by next generation deep sequencing of the amplified targets. Evaluation of the performance of these assays for screening for cancer in asymptomatic subjects is essential for the clinical validation of the use of these assays. The specific aim of this protocol is to obtain relevant human blood samples from individual subjects at higher than average risk for the development of cancer due to age, heredity, or environmental or toxic exposures for use in the statistical analysis of this method as an adjunct screening test for the potential presence of cancer.

Effects of Chemoradiation and Surgery on Cardiopulmonary Fitness and Tumor Neoplastic Phenotype in Gastrointestinal Malignancies
Description

There is growing evidence of the integral role of exercise following cancer treatment. Randomized trials show that exercise improves post treatment symptoms and quality of life in breast and prostate cancer patients.Regular exercise reduces cancer specific and all cause mortality for patients with breast, prostate, brain or colorectal cancer. Nearly a 40-50% relative risk reduction in cancer specific death and 20-50% relative risk reduction in all cause mortality have been reported with exercise. At present it is unknown if preclinical pleiotropic effects on tumors through aerobic exercise are clinically relevant. Before launching into further studies of exercise training on changes in tumor hypoxia and response to CRT in rectal cancer patients, it is first important to understand: 1. Whether measures of exercise exposure (i.e., exercise capacity and self-reported exercise behavior) are associated with markers of tumor hypoxia at diagnosis (prior to initiation of CRT) and 2. Whether changes in measures of exercise exposure over the course of CRT are related to changes in tumor hypoxia and response to CRT.

Prospective Follow-up of Outcomes in Patients Receiving Photodynamic Therapy for Neoplastic Diseases
Description

From 1996-present, we have used photodynamic therapy (PDT) to treat a number of neoplastic diseases both on prospective research protocols (for head and neck cancer, pleural malignancies, peritoneal carcinomatosis or sarcomatosis and prostate cancer) as well as for FDA approved and off label or compassionate exemption indications (neoplasms of the skin, bronchus, esophagus, head and neck and pleura). The goal of this treatment is to maximize quality of life and organ function while minimizing the chance of tumor recurrence. As such, we would like to retrospectively review the treatment parameters of all patients who undergo/underwent PDT (including operative notes and photodynamic therapy records) and treatment outcomes (including all organ functions, performance status, tumor recurrence, laboratory values and any other data present in the routinely documented follow up visits). For patients who have died or were lost to follow-up prior to initiation of this study, a retrospective review of available data will be performed. For patients who are still being actively followed after PDT or who receive PDT after the initiation of this study, informed consent will be obtained for obtaining continued follow-up data prospectively and any previous data will be collected retrospectively.. These subjects will continue to receive care from their current physicians according to standard medical practice and no attempt will be made to alter the types of follow-up, radiologic or other diagnostic studies or medical treatment as a result of enrollment in this study. All data will be de-identified and added to our already existing PDT treatment outcome databases for outcomes analysis, quality improvement and reporting of results in abstract and manuscript forms.

Induction of Suction Blisters in Patients With Urticaria, Blistering Diseases, Inflammatory Dermatoses and Neoplastic Disorders, and in Normal Volunteers
Description

The use of a suction blister apparatus has facilitated study of the immunologic capacity of human epidermal cells. We have been able to prepare purified populations of these cells after blister formation. Specifically, using the blister tops, we are able to enrich for epidermal Langerhans cells which are very potent stimulators in antigen presenting assays. Thus, this normal volunteer study provides an important source of fresh epidermal tissue from which we can study normal epidermal Langerhans cell function. In addition, we have recently used blister roofs in important experimental models of HIV-1 transmission. There is no other method available for assessing the biologic function of freshly isolated Langerhans cells without altering their milieu. It is a very safe and effective way to obtain human epidermal samples.

Indocyanine Green (ICG) Guided Tumor Resection
Description

This is a study to assess the ability of Indocyanine Green (ICG) to identify neoplastic disease. For many pediatric solid tumors, complete resection of the primary site and/or metastatic deposits is critical for achieving a cure. An optimal intra-operative tool to help visualize tumor and its margins would be of benefit. ICG real-time fluorescence imaging is a technique being used increasingly in adults for this purpose. We propose to use it during surgery for pediatric malignancies. All patients with tumors that require localization for resection or biopsy of the tumor and/or metastatic lesions will be eligible. Primary Objective To assess the feasibility of Indocyanine Green (ICG)-mediated near-infrared (NIR) imagery to identify neoplastic disease during the conduct of surgery to resect neoplastic lesions in children and adolescents. NIR imaging will be done at the start of surgery to assess NIR-positivity of the lesion(s) and at the end of surgery to assess completeness of resection. Separate assessments will be made for the following different histologic categories: 1. Osteosarcoma 2. Neuroblastoma 3. Metastatic pulmonary deposits - closed to accrual Exploratory Objectives 1. To compare the ICG uptake by primary vs metastatic site and pre-treated (chemotherapy, radiation, or both) vs non-pre-treated. 2. Assess the sensitivity and specificity of NIR imagery to find additional lesions not identified by standard of care intraoperative inspection and tactile feedback. 3. Assess the sensitivity and specificity of NIR imagery to find additional lesions not identified on preoperative diagnostic imaging. 4. Assess the sensitivity and specificity of NIR imagery for identifying residual disease at the conclusion of a tumor resection. Separate assessments will be made for the following different histologic categories based on their actual enrollment; this includes but is not limited to analyzing multiple arms together: 1. Ewing Sarcoma 2. Rhabdomyosarcoma (RMS) 3. Non-Rhabdomyosarcoma Soft Tissue Sarcoma (NRSTS) 4. Renal tumors 5. Liver tumors, lymphoma, other rare tumors, and nodules of unknown etiology

Donor Stem Cell Transplant With Treosulfan, Fludarabine, and Thiotepa in Treating Patients With Non-malignant Disorders
Description

This phase II clinical trial studies how well treosulfan, thiotepa, fludarabine, and rabbit anti-thymocyte globulin (rATG) before donor stem cell transplantation works in treating patients with nonmalignant (non-cancerous) diseases. Hematopoietic cell transplantation has been shown to be curative for many patients with nonmalignant (non-cancerous) diseases such as primary immunodeficiency disorders, immune dysregulatory disorders, hemophagocytic lymphohistiocytosis, bone marrow failure syndromes, and hemoglobinopathies. Powerful chemotherapy drugs are often used to condition the patient before infusion of the new healthy donor cells. The purpose of the conditioning therapy is to destroy the patient's abnormal bone marrow which doesn't work properly in order to make way for the new healthy donor cells which functions normally. Although effective in curing the patient's disease, many hematopoietic cell transplantation regimens use intensive chemotherapy which can be quite toxic, have significant side effects, and can potentially be life-threatening. Investigators are investigating whether a new conditioning regimen that uses less intensive drugs (treosulfan, thiotepa, and fludarabine phosphate) results in new blood-forming cells (engraftment) of the new donor cells without increased toxicities in patients with nonmalignant (non-cancerous) diseases.

Brentuximab Vedotin and Lenalidomide in Treating Patients With Relapsed or Refractory T-Cell Lymphomas
Description

This phase I trial studies the side effects and best dose of lenalidomide when given together with brentuximab vedotin in treating patients with T-cell lymphomas that have come back or do not respond to treatment. Monoclonal antibodies, such as brentuximab vedotin, may interfere with the ability of cancer cells to grow and spread. Drugs used in chemotherapy, such as lenalidomide, 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. Giving brentuximab vedotin and lenalidomide may work better in treating patients with T-cell lymphomas.

Changes in Biomarkers From Blood Over Time in Patients With Pancreatic Adenocarcinoma
Description

Pancreatic adenocarcinoma (PDAC) is the fourth leading cause of cancer mortality in the United States. The high mortality for these tumors is primarily attributed to the late stage in which most patients are diagnosed, leading to a dismal 5-year survival of 6% for all stages of PDAC. Surgical resection offers the best chance for survival, but most patients only present with symptoms after the tumor has metastasized, and as a result are not operative candidates. This creates a need to both identify patients at an earlier stage while their cancer is still resectable, and predict the aggressiveness of the disease in order to better target treatment. In addition, even patients who receive curative surgery are at a high risk of developing recurrence of disease. Thus, there is also a need to detect recurrence early so appropriate treatment can be provided. As several adjuvant chemotherapeutic regimens are now available, it will be important to identify as soon as possible that the cancer has become refractory to a given therapy. This will allow one to progress to second or third line therapy more quickly while the tumor burden is smaller. This purpose of this study is to identify biomarkers in the blood of patients with PDAC and determine how they can change over time in relation to treatment to assess for any correlation with patient outcomes, response to treatment, recurrence of disease and overall survival. This study will be limited to patients who present to the Johns Hopkins Hospital between January 1, 2015 and December 31, 2018 with PDAC. Blood will be drawn from all consenting patients at the time of initial diagnosis and after treatment. Patients will undergo treatment for their cancer based on personal preference, standard guidelines and discussion with medical, radiation, and surgical oncologists. Patients who undergo surgical resection will also have an additional blood sample collected after resection, and patients who undergo chemotherapy and/or radiation will have an additional blood sample draw at the end of this treatment. A patient could have blood collected at multiple intervals, i.e. a pre-treatment sample, sample post-neoadjuvant chemotherapy/radiation, sample post-surgery, and sample post-adjuvant chemotherapy/radiation. In patients, who have undergone curative resection of PDAC blood samples will be collected till they develop clinical recurrence of disease. For the first 2 years following surgery samples will be collected every 3-4 months. Beyond that the investigators will collect samples every 6 months for the next two years. For all patients found to be alive and disease free beyond 4 years after surgery samples will be collected once every year. These patients will be followed to determine disease-free and overall survival. With this study, the investigators aim to assess the potential utility of blood biomarkers over time for pancreatic tumors which will help both with early detection of disease and also recurrence of disease after surgery. Biomarkers identified would have the potential to create a new method for early diagnosis of patients with PDAC, predict overall survival, response to treatment, or risk of metastatic spread, and predict recurrence of disease, all of which has the potential to drastically improve outcomes for this deadly disease.
