This phase III trial studies whether inotuzumab ozogamicin added to post-induction chemotherapy for patients with High-Risk B-cell Acute Lymphoblastic Leukemia (B-ALL) improves outcomes. This trial also studies the outcomes of patients with mixed phenotype acute leukemia (MPAL), and B-lymphoblastic lymphoma (B-LLy) when treated with ALL therapy without inotuzumab ozogamicin. Inotuzumab ozogamicin is a monoclonal antibody, called inotuzumab, linked to a type of chemotherapy called calicheamicin. Inotuzumab attaches to cancer cells in a targeted way and delivers calicheamicin to kill them. Other drugs used in the chemotherapy regimen, such as cyclophosphamide, cytarabine, dexamethasone, doxorubicin, daunorubicin, methotrexate, leucovorin, mercaptopurine, prednisone, thioguanine, vincristine, and pegaspargase or calaspargase pegol 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 will also study the outcomes of patients with mixed phenotype acute leukemia (MPAL) and disseminated B lymphoblastic lymphoma (B-LLy) when treated with high-risk ALL chemotherapy. The overall goal of this study is to understand if adding inotuzumab ozogamicin to standard of care chemotherapy maintains or improves outcomes in High Risk B-cell Acute Lymphoblastic Leukemia (HR B-ALL). The first part of the study includes the first two phases of therapy: Induction and Consolidation. This part will collect information on the leukemia, as well as the effects of the initial treatment, to classify patients into post-consolidation treatment groups. On the second part of this study, patients with HR B-ALL will receive the remainder of the chemotherapy cycles (interim maintenance I, delayed intensification, interim maintenance II, maintenance), with some patients randomized to receive inotuzumab. The patients that receive inotuzumab will not receive part of delayed intensification. Other aims of this study include investigating whether treating both males and females with the same duration of chemotherapy maintains outcomes for males who have previously been treated for an additional year compared to girls, as well as to evaluate the best ways to help patients adhere to oral chemotherapy regimens. Finally, this study will be the first to track the outcomes of subjects with disseminated B-cell Lymphoblastic Leukemia (B-LLy) or Mixed Phenotype Acute Leukemia (MPAL) when treated with B-ALL chemotherapy.

This study is researching an experimental drug called linvoseltamab combined with another drug called dupilumab. The study is looking at patients who have severe IgE-mediated food allergy. If the patient has an allergy, the body's defense system (immune system) overreacts to an allergen (eg, certain foods like peanuts, milk, shellfish) by making antibodies called IgE. An antibody is a protein that allows the immune system to find and fight off things the body does not recognize (allergens). IgE antibodies are sent out by cells like plasma cells. These antibodies and allergens bind to other cells that send out chemicals, causing an allergic reaction. The aim of the study is to see what side effects happen when linvoseltamab is combined with dupilumab. The study is looking at several other research questions, including: - What side effects may happen from taking the study drugs - Does linvoseltamab combined with dupilumab affect other types of antibodies in the blood at different times - How much study drug(s) is in the blood at different times Type: Interventional Start Date: May 2024 |

This phase III trial compares standard chemotherapy to therapy with liposome-encapsulated daunorubicin-cytarabine (CPX-351) and/or gilteritinib for patients with newly diagnosed acute myeloid leukemia with or without FLT3 mutations. Drugs used in chemotherapy, such as daunorubicin, cytarabine, and gemtuzumab ozogamicin, 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. CPX-351 is made up of daunorubicin and cytarabine and is made in a way that makes the drugs stay in the bone marrow longer and could be less likely to cause heart problems than traditional anthracycline drugs, a common class of chemotherapy drug. Some acute myeloid leukemia patients have an abnormality in the structure of a gene called FLT3. Genes are pieces of DNA (molecules that carry instructions for development, functioning, growth and reproduction) inside each cell that tell the cell what to do and when to grow and divide. FLT3 plays an important role in the normal making of blood cells. This gene can have permanent changes that cause it to function abnormally by making cancer cells grow. Gilteritinib may block the abnormal function of the FLT3 gene that makes cancer cells grow. The overall goals of this study are, 1) to compare the effects, good and/or bad, of CPX-351 with daunorubicin and cytarabine on people with newly diagnosed AML to find out which is better, 2) to study the effects, good and/or bad, of adding gilteritinib to AML therapy for patients with high amounts of FLT3/ITD or other FLT3 mutations and 3) to study changes in heart function during and after treatment for AML. Giving CPX-351 and/or gilteritinib with standard chemotherapy may work better in treating patients with acute myeloid leukemia compared to standard chemotherapy alone.

This is a Phase II parallel group randomized controlled trial with 294 adolescents (age: 14-21 years) with alcohol and other drug [AOD] use disorder (hereafter substance use disorder), that compares two different active psychosocial interventions designed to address adolescent substance use disorder. Participants are recruited from our clinical settings and the community at two sites: one in the metro Boston, Massachusetts (MA) area and the other in the metro Farmington, Connecticut (CT), area. Study aims and hypotheses are as follows: 1. To extend the evidence for the initial efficacy of Integrated Treatment for Enhancing Growth in Recovery During Adolescence (InTEGRA), which integrates 12-Step Facilitation (TSF) with Motivational Enhancement Therapy/Cognitive Behavioral Therapy (MET/CBT) relative to gold standard MET/CBT alone (N = 294). It is hypothesized that youth assigned to InTEGRA will have greater 12-step participation during and following treatment, higher abstinence rates, and fewer substance-related negative consequences. 2. Investigate the personal recovery capital (PRC) and social recovery capital (SRC) mechanisms of behavior change through which InTEGRA may confer benefits dynamically over time (e.g., PRC: motivation, self-efficacy, coping; SRC: 12-step involvement; social network changes). 3. Investigate moderators of InTEGRA's effects on outcomes across one-year follow-up (e.g., effect of age, network support for AOD use; psychiatric severity; age composition of 12-step meetings on substance use and substance-related consequences). It is hypothesized that higher network support for AOD use, abstinence motivation, and greater AOD severity, will have a better response to InTEGRA. 4. Explore barriers and facilitators to InTEGRA adoption and implementation across providers and system administrators within the context of a type I hybrid effectiveness-implementation research design.

The objective of this study protocol is to test whether intermittent theta-burst transcranial magnetic stimulation (iTBS-TMS) to the inferior parietal lobule (IPL) can strengthen functional connectivity with a key region in emotion regulation (ER) neurocircuitry (anterior insula, AI) and improve performance on ER-related tasks in patients with bipolar disorder. Individual IPL sites for stimulation will be identified through baseline, pre-TMS functional magnetic resonance imaging (fMRI) scans. Patient-specific IPL subregions showing positive functional connectivity with the anterior insula and falling within the patient-specific frontoparietal control network will be used as individualized target sites for TMS stimulation. Patients will be randomized to receive 24 sessions of active versus sham iTBS to patient-specific IPL targets (6 sessions/day, 4 days, 43,200 pulses total). Post-iTBS resting-state and task-based fMRI scans will be acquired 3 days after the final day of iTBS administration (Day 4) following identical procedures as baseline. Effects of iTBS-TMS on ER will be evaluated by comparing pre-TMS versus post-TMS functional connectivity and behavior during performance on ER tasks. Type: Interventional Start Date: Sep 2024 |

Men who have sex with men (MSM), and gender minority individuals who have sex with men, living with HIV and substance use disorders (SUDs) are less likely to be virally suppressed, which can lead to HIV transmission and negative health outcomes. This hybrid type 1 study will assess the efficacy, mechanisms, as well as facilitators and barriers to implementing the MATTER intervention, a virtually delivered 5-session text-enhanced psychobehavioral intervention designed to facilitate viral suppression by addressing internalized stigma and shame as barriers to engagement in HIV care among MSM and gender minority individuals living with HIV and SUDs in two locations with different levels of HIV resources (i.e., the Boston, Massachusetts and Miami, Florida metro areas). MATTER aims to mitigate the negative behavioral consequences of internalized stigma and shame on viral suppression by a) developing behavioral self-care goal setting skills and related self-efficacy, b) increasing metacognitive awareness (i.e., non-judgmental awareness of emotions and cognitions), and c) teaching and reinforcing compassionate self-restructuring (i.e., self- compassion), in addition to providing access to phone-based resource navigation.

Persistent developmental stuttering affects more than three million people in the United States, and it can have profound adverse effects on quality of life. Despite its prevalence and negative impact, stuttering has resisted explanation and effective treatment, due in large part to a poor understanding of the neural processing impairments underlying the disorder. The overall goal of this study is to improve understanding of the brain mechanisms involved in speech motor planning and how these are disrupted in neurogenic speech disorders, like stuttering. The investigators will do this through an integrated combination of experiments that involve speech production, functional MRI, and non-invasive brain stimulation. The study is designed to test hypotheses regarding the brain processes involved in learning and initiating new speech sound sequences and how those processes compare in persons with persistent developmental stuttering and those with typical speech development. These processes will be studied in both adults and children. Additionally, these processes will be investigated in patients with neurodegenerative speech disorders (primary progressive aphasia) to further inform the investigators understanding of the neural mechanisms that support speech motor sequence learning. Together these experiments will result in an improved account of the brain mechanisms underlying speech production in fluent speakers and individuals who stutter, thereby paving the way for the development of new therapies and technologies for addressing this disorder.
