Researchers are investigating the specific targets of T cells involved in autoimmune diseases by studying tissues from patients with active organ inflammation caused by autoimmune conditions. The study aims to identify which T cells are activated and expanding in diseased tissues compared to blood or normal tissues. This information will help discover new peptide targets and their associated T cell receptors TCRs to develop potential new therapies for autoimmune diseases. Participants will provide tissue samples and matched blood samples during clinical procedures such as endoscopy, arthrocentesis, lumbar puncture, skin biopsy, bronchoscopy, or surgery, depending on their autoimmune condition. The study includes several groups covering diseases like Crohns disease, ulcerative colitis, celiac disease, ankylosing spondylitis, multiple sclerosis, scleroderma, systemic sclerosis, and other autoimmune diseases. Samples may come from excess clinical materials or research-specific biopsies, with the possibility of serial sampling over time. During the study, participants will undergo standard clinical procedures with collection of additional tissue or fluid samples and companion blood draws. Researchers will analyze these samples to identify peptide targets linked to disease-reactive T cells over a period of up to three years. The study includes comprehensive assessments of tissues and blood to understand T cell activity in autoimmune disorders, with monitoring of participant safety and no interventions beyond routine clinical care.

Researchers are studying metastatic castration-resistant prostate cancer mCRPC to find new treatment options. This trial evaluates if the study medicine ifinatamab deruxtecan I-DXd or MK-2400 helps people live longer overall and experience slower cancer growth or spread compared to chemotherapy. The study is a Phase 3 trial comparing I-DXd with standard chemotherapy for mCRPC patients. Participants are randomly assigned to receive either I-DXd at 12 mgkg every 3 weeks through intravenous infusion or docetaxel chemotherapy at 75 mgm2 every 3 weeks combined with daily prednisone pills. Treatment continues until the disease progresses, unacceptable side effects occur, or treatment is stopped for other reasons. Premedication is given before each dose of I-DXd to help prevent nausea and vomiting. During the study, participants will have regular visits for treatment and monitoring. Researchers will assess overall survival and radiographic progression-free survival for up to about 36 months. Additional measures include response rates, time to pain progression, PSA progression, and adverse events. The study tracks safety, treatment effects, and quality of life over a long follow-up period to better understand the potential benefits and risks of I-DXd compared to chemotherapy.

Researchers are studying pulmonary arterial hypertension PAH, a condition where lung blood vessels become thick and narrow, causing high blood pressure in the lungs and making it hard for the heart to work. PAH can cause difficulty breathing and limit activity. While standard treatments help symptoms, they do not stop the disease from worsening. This research focuses on sotatercept, a targeted therapy aimed at specific proteins involved in PAH, to learn about its long-term safety and tolerability when added to usual PAH treatments. Participants in this long-term follow-up study, who previously took part in certain sotatercept trials, may continue receiving sotatercept by subcutaneous injection every three weeks. Those coming from blinded studies start at 0.3 mgkg with possible increases up to 0.7 mgkg, while those from unblinded studies continue their current dose with possible titration to 0.7 mgkg. The study monitors participants over an extended period to assess continued effects alongside their usual PAH therapy. During the study, participants will have regular assessments including monitoring for adverse events, blood tests for blood components and chemistry, body weight, blood pressure, and ECG readings. Researchers will also evaluate exercise capacity, heart function markers, and risk scores related to PAH. The study aims to follow participants for up to approximately 7 to 8 years to understand long-term safety, treatment tolerability, and health changes while using sotatercept with standard PAH care.

Researchers are evaluating treatments for germinal center B-cell-like diffuse large B-cell lymphoma GCB DLBCL, a fast-growing blood cancer affecting immature B-cells. The study compares two treatment combinations to see if more people respond to zilovertamab vedotin MK-2140 plus R-CHP versus polatuzumab vedotin plus R-CHP. This Phase 2 trial aims to assess the effectiveness and safety of these regimens in participants with newly diagnosed GCB DLBCL. Participants receive either zilovertamab vedotin along with rituximab, cyclophosphamide, doxorubicin, and prednisone R-CHP, or polatuzumab vedotin combined with R-CHP. Treatments are given by intravenous infusion on Day 1 of each 3-week cycle for up to 6 cycles, approximately 4 months, with prednisone or prednisolone taken orally for 5 days of each cycle. For participants with high-risk DLBCL, up to 2 additional cycles of rituximab or biosimilar are given. During the study, participants are monitored for response to treatment using Lugano Response Criteria, with follow-up lasting up to about 31 months for the primary outcome. Secondary outcomes include progression-free survival, overall survival, event-free survival, duration of complete response, adverse events, and quality of life assessments. Safety and health status are regularly checked through exams, lab tests, and questionnaires over several years, with total study participation extending up to 7 years.

Researchers are evaluating a culturally-tailored home-based physical activity program designed for Hispanic or LatinoLatina adolescent and young adult childhood cancer survivors. These survivors may face long-term effects like weight gain, fatigue, and reduced physical fitness after cancer treatment. The study aims to see if this culturally-relevant program can help increase physical activity and improve overall health compared to using a Fitbit tracker alone. The study has two stages. In Stage 1, 20 Latinx survivors participate in developing the intervention using Fitbit trackers, text messages, social media support, wearable activity devices, and interviews over 9 months. In Stage 2, 170 survivors who do not meet physical activity guidelines are randomized to either the intervention group, which includes Fitbit use, weekly goal-setting, peer support via social media and Zoom meetings, and optional activity partners, or a control group that only uses Fitbit trackers for 12 weeks. The intervention includes an intensive phase with weekly sessions followed by a 4-week maintenance phase. Participants will wear Fitbit trackers daily and engage in goal-setting, peer discussions, and physical activity reminders. Researchers will measure moderate to vigorous physical activity, sedentary time, and health-related quality of life over 12 weeks. Additional evaluations include physiological markers of heart and metabolic health and qualitative interviews to improve the program. The study lasts through the intervention phases with ongoing monitoring and support for participants.

Researchers are studying MEN2312, a lysine acetyltransferase 6 KAT6 inhibitor, in adults with advanced breast cancer that is not curable. This first-in-human, phase 1 study evaluates MEN2312 alone and in combination with elacestrant to understand its safety and determine the best dose. Participants have specific genetic alterations in their tumors and have received prior endocrine therapy and cyclin-dependent kinase 4 and 6 inhibitor treatment. Participants will be randomly assigned to receive either MEN2312 by itself or MEN2312 combined with elacestrant, both given as oral tablets. The study follows a sequential design and aims to identify dose-limiting toxicities and recommend the phase 2 dose over several months of treatment. This includes monitoring drug levels in the body and how the body processes the medications. During the study, participants will have regular assessments to monitor side effects, tumor response, and overall health. These include evaluating the number of dose-limiting toxicities within the first 28 days and tracking response rates, progression-free survival, and overall survival for up to nine months after treatment ends. Researchers will also measure drug concentration and excretion to better understand the treatment effects and safety over time.

Primary immune thrombocytopenia ITP is a condition where the immune system mistakenly destroys platelets, leading to a lower number of platelets and increased risk of bruising or bleeding. This Phase 3 study evaluates the long-term safety, tolerability, and effectiveness of mezagitamab in adults with chronic primary ITP. The study also investigates how the body processes mezagitamab over an extended period. Participants who completed previous mezagitamab studies TAK-079-3002 or TAK-079-1004 will be invited to join this continuation trial. Eligible participants may receive mezagitamab injections on demand, with treatment courses repeated as needed based on specific criteria and the investigators clinical judgment. The treatment is administered subcutaneously. During the study, participants will visit the clinic several times for assessments. Researchers will monitor safety by tracking treatment-emergent adverse events, and evaluate effectiveness through platelet response and remission rates. Measurements of drug levels and antibodies will also be taken. The study may last up to approximately 108 weeks, allowing detailed long-term follow-up.

Researchers are conducting a 10-year multi-center, prospective, longitudinal study in the United States to observe immunologic, inflammatory, and laboratory changes in people with phenylketonuria PKU who are treated with Palynziq pegvaliase. The study includes both new users starting pegvaliase within 30 days after enrolling in a related study 165-501 and those who have already been receiving the treatment before enrollment. The goal is to understand long-term immune and inflammatory responses to this treatment. Participants must already be enrolled in the 165-501 study to join this study. They will provide blood samples before dosing every three months for the first three years, then every six months for the remaining study period. Additional blood samples may be taken during safety events as defined in the related 165-501 study protocol, and standard care blood draws are also incorporated. Blood tests will measure phenylalanine levels and various immune and inflammatory markers, which will be processed centrally. During the study, data from this observational study will be combined with data from the 165-501 study to reduce duplicate reporting and lessen the burden on study sites. Participants may withdraw from this study while continuing in the 165-501 study, but not vice versa, to ensure safety monitoring. The research team will evaluate immune and inflammatory responses over up to 10 years of treatment, tracking changes through blood tests and clinical data collection for a comprehensive understanding of long-term effects.

This research follows patients with Hemoglobinopathy and Sickle Cell Disease who previously received BEAM-101, a gene-edited cell treatment, in an earlier study. The trial is a long-term observational follow-up to monitor safety and health outcomes over an extended period. It aims to gather important information about the long-term effects and risks after receiving BEAM-101 treatment. Participants in this study have received a single dose of BEAM-101 by intravenous infusion after a conditioning treatment with busulfan. This follow-up study will track their health for 13 years, adding up to 15 years from the initial treatment. Study visits will happen annually for the first 5 years, then every 3 years until year 11, with a final visit at year 15. Additionally, virtual or phone check-ins will occur every 6 months for the first 5 years, then annually thereafter. During the study, participants will undergo regular safety and efficacy assessments to monitor their health, including how well they remain free of severe sickle cell crises and their blood hemoglobin levels. Researchers will review long-term safety data and mortality over the 13 years. The study includes blood tests and other evaluations at scheduled visits and check-ins. Participation will last up to 15 years, with ongoing monitoring to understand the lasting impact of BEAM-101 treatment.

This study focuses on participants who have previously been treated with ciltacabtagene autoleucel cilta-cel, an autologous CAR-T therapy targeting B-cell maturation antigen BCMA used in multiple myeloma. The purpose is to collect long-term follow-up data to understand delayed adverse events and the long-term safety profile of cilta-cel over a period of up to 15 years after the last dose. Participants were originally treated in company-sponsored clinical trials evaluating cilta-cel. No treatment is administered during this follow-up study. Participants will be observed in two phases the first phase covers the initial 5 years after their last cilta-cel dose, and the second phase covers years 6 through 15 post-treatment. The study includes yearly safety evaluations involving review of adverse events, laboratory tests, and physical examinations including neurological assessments. Participants will be followed up at least once per year for up to 15 years to monitor for new or worsening medical conditions such as malignancies, neurological or autoimmune disorders, hematologic disorders, infections, and serious adverse events. The research team will also assess laboratory markers related to the CAR-T therapy, such as lentivirus presence and CAR transgene levels. This extended monitoring aims to provide a comprehensive safety profile of cilta-cel over the long term.
