Blood and Marrow Transplant Clinical Trials Network A Trial of Single Autologous Transplant With or Without Consolidation Therapy Versus Tandem Autologous Transplant With Lenalidomide Maintenance for Patients With Multiple Myeloma (BMT CTN-0702-BioLINCC)

Data Access NOTE: Please refer to the “Authorized Access” section below for information about how access to the data from this accession differs from many other dbGaP accessions.Objectives: To compare the use of tandem autologous hematopoietic cell transplantation (AHCT) followed by lenalidomide maintenance, AHCT plus four cycles of lenalidomide, bortezomib, and dexamethasone (RVD) followed by lenalidomide, and AHCT and lenalidomide only in improving outcomes for patients with active multiple myeloma (MM).Background: At the time of this trial, initial myeloma reductive therapy followed by high-dose melphalan plus AHCT with long-term lenalidomide was the standard of care for patients newly diagnosed with MM in the United States. Despite substantive improvements in outcomes with the addition of lenalidomide, most patients still experienced disease progression and ultimately died as a result of the disease. Several approaches to further improve outcome after initial AHCT have been investigated but incremental benefit compared with maintenance therapy remains to be determined. This trial was initiated to assess whether the additional interventions of second AHCT or RVD consolidation to AHCT and lenalidomide further improve outcomes.Participants: Patients with symptomatic MM who were 70 years old or younger, had a Karnofsky score equal to or greater than 70, received at least two cycles of any regimen as initial systemic therapy without disease progression, and were within 2 to 12 months of the first dose of initial therapy were eligible.758 patients were enrolled. 247 patients were randomly assigned to the AHCT/AHCT + lenalidomide arm, 254 patients to the AHCT + RVD + lenalidomide arm, and 257 patients to the AHCT + lenalidomide arm.Design: The BMT CTN-0702 study was a Phase III multicenter trial. All patients were randomly assigned in a 1:1:1 manner at the time of enrollment, which occurred within 7 days before the first high-dose melphalan conditioning regimen. Random assignment was stratified by disease risk and transplantation center. High-risk MM was defined by presence of high β2-microglobulin, presence of cytogenetic abnormalities, or aneuploidy. Patients without cytogenetic analysis available and low β2-microglobulin level (≤5.5 mg/L) or with deletion 13 detected by fluorescence in situ hybridization were classified as standard risk.All enrolled patients were to receive high-dose melphalan (200 mg/m2) followed by mobilized autologous peripheral-blood stem-cell infusion (minimum 2 × 106 CD34+ cells/kg). Subsequent therapy was based on random assignment at the time of enrollment. The second phase of therapy started between 60 and 120 days after the first AHCT, once patients had sufficiently recovered. Patients randomly assigned to a second transplantation received high-dose melphalan (200 mg/m2) followed by autologous peripheral-blood stem-cell infusion. Patients randomly assigned to RVD consolidation received four cycles of lenalidomide 15 mg/d on days 1 to 14; bortezomib 1.3 mg/m2 on days 1, 4, 8, and 11 of every 21-day cycle; and dexamethasone 40 mg per day on days 1, 8, and 15. After their initial interventions, all patients received lenalidomide starting at 10 mg per day for 3 months and increasing to 15 mg per day. Dose adjustments for toxicity were permitted. Maintenance therapy was initially designed to be given for 3 years to all patients. An amendment expanded use of lenalidomide to continue until toxicity, disease progression, or withdrawal of consent.Quality of life was assessed using the Short Form 36 and Functional Assessment of Cancer Therapy-Bone Marrow Transplant at baseline and yearly.The primary study end point was progression free survival at 38 months.Conclusions: Second AHCT or RVD consolidation as post-AHCT interventions for the up-front treatment of transplantation-eligible patients with multiple myeloma did not improve progression free survival or overall survival. Single AHCT and lenalidomide should remain as the standard approach for this population.

Interdisciplinary Approaches for Understanding how Arsenic and Micronutrients Affect the Epigenome to Influence Spina Bifida Risk

This hospital-based case-control study was conducted in Bangladesh between December 2016 and December 2022 to investigate the association between environmental arsenic exposure and the risk of spina bifida. The study enrolled children with spina bifida (cases) and unaffected children (controls), along with their biological parents. Cases included infants under one year of age with clinically confirmed diagnoses of myelomeningocele or meningocele at the National Institute of Neurosciences & Hospital (NINS). Controls were frequency-matched on age and recruited from the same catchment area through NINS and Dhaka Shishu Hospital. Children with conditions potentially related to arsenic exposure, such as keratosis or cancer, were excluded from the control group. A small subset of case families were reclassified as controls following surgical reevaluation and a revised diagnosis of lipomeningocele, then later removed from the control group. They are no longer assigned to either the case or control category in the datasets. Saliva samples were collected from children and parents using Oragene® kits and stored at room temperature before shipment to Boston, MA, USA. DNA extraction was carried out with the Maxwell® RSC Buccal Swab DNA kit. A total of 749 saliva DNA samples, representing 713 unique individuals and 36 replicates, were shipped to the Broad Institute for analysis. Samples were randomized across Illumina Global Screening Array (GSA) chips to minimize batch effects. The primary molecular technology employed in this study was the Illumina Global Screening Array (GSAMD-24v1-0), which includes approximately 688,000 genetic markers. Data generated include raw and processed genotype files as well as a comprehensive quality control report. The genotyping dataset available through dbGaP will consist of genotype calls from spina bifida cases, controls, and their parents, along with associated demographic, clinical, and exposure metadata, enabling future analyses of gene-environment interactions in the context of neural tube defect risk.

Childhood Cancer Data Initiative (CCDI): Whole Genome Landscapes of Patient Derived Osteosarcoma Xenograft Models

Osteosarcoma is the most common primary bone malignancy in children and young adults and has few treatment options. As a result, there has been little improvement in survival outcomes over the past few decades. The need for models to test novel therapies is especially great for this disease because it is both rare and unresponsive to most therapies. To address this need, an NCI-funded consortium has characterized and utilized a panel of patient-derived xenograft models of osteosarcoma for drug testing. The exomes, transcriptomes, and copy number landscapes of these models have been described previously. This study adds whole-genome sequencing (WGS) and reverse-phase protein array profiling data, which can be correlated with drug testing results. In addition, four new osteosarcoma models are described for use by the research community.

Transcriptional Signatures Indicating RB Function Correlate with Response to CDK4/6 Inhibition in Endometrial Cancer

Here we provide exome-capture RNA sequencing data from 39 endometrial cancer samples from women who participated in two separate abemaciclib combination clinical trials. In addition, whole exome sequencing data are provided for a subset of the tumors for which enough material remained. In the original publication, specific RNA sequencing results were matched to objective response status of the patients in the trials, and it was shown that specific transcriptional signatures could predict function of the RB tumor suppressor and response to abemaciclib in the trials. This study is published. Please cite the original source publication Yang, et al., 2026, PMID: 42531366, for which the data were generated and analyzed.

Effector CD4 T Cells Convert Transient Responses to KRAS-Targeted Therapy into Long-Term Durable Remissions in Pancreatic Cancer

Pancreatic ductal adenocarcinoma (PDAC) is refractory to most therapies, including immunotherapies in which reinvigoration of CD8 T cells is insufficient to induce durable long-term remissions. Direct KRAS inhibitors are clinically promising; however, acquired resistance is common. Using AI-assisted computational design, we developed a de novo IL-21 mimic, 21h10, with enhanced stability and high signaling potency in both humans and mice. Using an orthotopic PDAC mouse model, we evaluated responses and relapse following KRAS inhibitor treatment and demonstrated that, unlike combinations with chemotherapy or checkpoint blockade, the combination of 21h10 and KRAS inhibition is curative. Single-cell transcriptional profiling with TCR-seq revealed oligoclonal expansion of effector Th1-polarized CD4 T cells and depletion of Tregs. To evaluate the efficacy of 21h10 in human samples, we performed single-cell RNA-seq analyses on treatment-naive specimens following short-term ex vivo treatment with 21h10. This dataset consists of Illumina NovaSeq sequencing output (FASTQ files) generated from tumor libraries prepared using the 10x Genomics Single Cell 5′ Immune Profiling platform. FASTQ files are provided for gene expression (GEX), TCR, and, for multiplexed samples, HTO libraries.

NCTN: Radiation Therapy and Cisplatin with or without Cetuximab in Treating Patients with Stage III or Stage IV Head and Neck Cancer (RTOG-0522)

Study ID: RTOG-0522NCT Number: NCT00265941 NRG OncologySubmitted in collaboration with the NCTN/NCORP Data ArchiveTrial Title: NCTN: A Randomized Phase III Trial of Concurrent Accelerated Radiation and Cisplatin vs Concurrent Accelerated Radiation, Cisplatin, and Cetuximab (C225) [followed by Surgery for Selected Patients] for Stage III and IV Head and Neck Carcinomas (RTOG-0522)Trial Description: RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Drugs used in chemotherapy, such as cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Cisplatin may also make tumor cells more sensitive to radiation therapy. Monoclonal antibodies, such as cetuximab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Giving radiation therapy and cisplatin together with cetuximab may kill more tumor cells. It is not yet known whether radiation therapy and cisplatin are more effective with or without cetuximab in treating head and neck cancer.PURPOSE: This randomized phase III trial is studying radiation therapy, cisplatin, and cetuximab to see how well they work compared to radiation therapy and cisplatin in treating patients with stage III or stage IV head and neck cancer.

Blood and Marrow Clinical Trials Network Evaluating Corticosteroids with Mycophenolate Mofetil vs. Corticosteroids with Placebo as Initial Systemic Treatment of Acute GVHD (BMT-CTN-0802-BioLINCC)

Data Access NOTE: Please refer to the “Authorized Access” section below for information about how access to the data from this accession differs from many other dbGaP accessions.ObjectivesExplore the difference in response and survival rates for individuals with acute graft versus host disease (aGVHD) who received mycophenolate mofetil (MMF) plus corticosteroids versus corticosteroids alone.BackgroundIndividuals with certain cancers, genetic blood diseases, autoimmune diseases, and skeletal dysplasia may be candidates to receive an allogeneic hematopoietic stem cell transplantation (HSCT) as a potentially curative measure. A common and often fatal complication of receiving the transplant is acute graft-versus host disease (aGVHD). Historically, aGVHD has been treated with corticosteroids alone but favorable response rates are less than half prompting the need for better treatment options.ParticipantsAdult and pediatric participants were eligible for this study if they were the recipient of an allogeneic HSCT and newly diagnosed with aGVHD. Participants also needed to be able to swallow the MMF or placebo capsules and have an absolute neutrophil count > 500 cells per μL without growth factors. Disqualifiers for study eligibility included receipt of MMF or mycophenolic acid within 7 days of screening, uncontrolled infections, hepatic veno-occlusive disease, chronic GVHD, or renal failure on dialysis.A total of 235 patients participated in the study. Participants were randomized into either a treatment or placebo group. There were 116 participants in the treatment or MMF arm and 119 participants in the placebo arm.DesignBMT CTN 0802 was a phase 3 multicenter randomized double-blinded trial. Randomization was stratified by transplant center and grade of aGVHD (I-II vs III-IV) at study entry. Eligible participants who required GVHD therapy were treated within 72 hours of enrollment. All patients in the study received corticosteroids at a dose of prednisone 2 mg/kg per day orally (or methylprednisolone 1.6 mg/kg per day IV). Patients were also given MMF or the placebo at a dose of 1000 mg or 20 mg/kg (for patients Response to treatment was classified as complete, partial, progression, no response, or flare. Complete response (CR) was defined as complete resolution of all signs and symptoms of aGVHD, and a partial response (PR) was defined as improvement of 1 stage in 1 or more organs involved by GVHD without progression in others. Progression was defined as worsening in 1 or more organs, and no response was defined as stable disease or absence of improvement in any organ involved by GVHD within 14 days of therapy initiation. A flare in GVHD was defined as any increase in symptoms or therapy for aGVHD after an initial response (CR or PR). All toxicities were reported regardless of whether they were thought to be related to the study treatment.Adult study participants who were able to communicate in English also completed the MD Anderson Symptom Inventory (MDASI), a tool used to measure quality of life. Participants completed the inventory at enrolment and at day 56 ± 7 days.The primary end point was acute or chronic GVHD-free survival at day 56 after initiation of therapy.ConclusionsResults for this study concluded that the addition of MMF to corticosteroids as initial therapy for acute GVHD does not improve GVHD-free survival compared with corticosteroids alone. There was also no difference between the treatment arms in regards to quality of life measures (Bolanos-Meade J, Logan B, Alousi A et al., Blood. 2014;124(22):3221-3227).

Trial of Activity for Adolescent Girls (TAAG-BioLINCC)

Data Access NOTE: Please refer to the "Authorized Access" section below for information about how access to the data from this accession differs from many other dbGaP accessions.ObjectivesThe purpose of the multicenter randomized trial was to test the effectiveness of a multicomponent school-based and community-linked intervention in preventing the decline in physical activity levels and cardiovascular fitness in middle school girls (i.e., in grades 6-8).BackgroundThe Report of the Surgeon General on Physical Activity and Health (USDHHS, 1996) emphasized that regular physical activity has important health benefits including reducing the risk of heart disease, and helping to treat and prevent high blood pressure, high cholesterol, and diabetes, and to prevent osteoporosis and colon cancer. In addition, physical activity helps control weight, reduces feelings of depression and anxiety, and promotes psychological well being. Inactivity increases with age and is more common among women than men and among those with lower income, less education, and in minorities (USDHHS, 1996). Even though adolescents are more active than adults, many do not engage in recommended levels of physical activity, and participation declines with age throughout adolescence, especially in girls (USDHHS, 1996; CDC, 1997). Fourteen percent of teenage girls get no regular exercise, twice the percentage as for boys. The proportion of adolescent girls who participate in regular vigorous physical activity declines dramatically each year they are in high school, from 61 percent among 9th graders to 41percent among 12th grade girls. In high school, enrollment for girls in daily physical education classes dropped from 41 percent in 1991 to 25 percent in 1995. Both the CDC report (1997) and the Surgeon General's Report (USDHHS, 1996) recommended the need for research testing the effectiveness of a coordinated school-based physical activity intervention linked to community agency programs to increase physical activity by adolescent girls.ParticipantsMiddle school girls with English-speaking skills and no conditions to prevent participation in physical activity in 36 schools in six geographically diverse areas of the United States. Random, cross-sectional samples were drawn within schools: 6th graders in 2003 (n 1721) and 8th graders in 2005 (n 3504) and 2006 (n 3502).Researchers receiving the TAAG data are encouraged to contact study investigators that have previously published TAAG data.ConclusionsA school-based, community-linked intervention modestly improved physical activity in girls.

FORCE Trial: Resistance Training Intervention Among Colon Cancer Patients

Our study population was composed of participants of the FORCE clinical trial, which was a randomized resistance training intervention study for Stage II and III colon cancer patients undergoing chemotherapy. Patients were recruited from Kaiser Permanente of Northern California, the Penn State Cancer Institute, and the Dana Farber Cancer Institute and were assigned to resistance training or usual care within the first weeks of adjuvant chemotherapy. Lean mass was evaluated at the beginning and the end of the study, and participants were monitored for toxicities associated with chemotherapy and chemotherapy dose modifications. Genome-wide DNA methylation was assayed using peripheral blood collected at the FORCE trial baseline and the post-intervention visit using the Infinium MethylationEPIC v1.0 (EPIC) BeadChips (Illumina). EPIC array signal intensities were preprocessed and used to estimate site-specific DNA methylation levels, which were used for the estimation of several epigenetic clocks. Our study hypothesized that those with accelerated epigenetic age at the beginning of chemotherapy would be more likely to have modifications to their assigned chemotherapy regimen driven by a higher burden of chemotoxicities. We also hypothesized that epigenetic age acceleration would significantly increase over the course of chemotherapy and that a resistance training intervention would reduce the rate of change.
