Testing a Standardized Approach to Surgery and Chemotherapy for Type I Pleuropulmonary Blastoma or the Addition of an Anti-cancer Drug, Topotecan, to the Usual Treatment for Types II and III Pleuropulmonary Blastoma

This phase III trial tests how well surgery plus chemotherapy compared to surgery alone works in treating patients with type I pleuropulmonary blastoma (PPB), and tests how well surgery plus standard chemotherapy with the addition of topotecan works compared to surgery plus standard chemotherapy alone in treating patients with type II and III PPB. Historically, most children with type I PPB had surgery and approximately 40% of children with type I PPB received chemotherapy following their surgery, usually for 22-42 weeks. There has not been a consistent standard for which children with type I PPB receive chemotherapy after surgery. For patients whose tumor has been removed completely with surgery, observation without chemotherapy may work as well as giving chemotherapy after surgery in preventing a return of the PPB tumor. The standard chemotherapy for patients with types II or III PPB in the United States is four cycles of IVADo (ifosfamide, vincristine, dactinomycin, and doxorubicin) followed by 8 cycles of IVA (ifosfamide, vincristine and dactinomycin). Ifosfamide is in a class of medications called alkylating agents. It works by slowing or stopping the growth of tumor cells in the body. Vincristine is in a class of medications called vinca alkaloids. It works by stopping tumor cells from growing and dividing and may kill them. Dactinomycin is a type of antibiotic that is only used in cancer chemotherapy (antineoplastic antibiotic). It works by damaging the cell's deoxyribonucleic acid (DNA) and may kill tumor cells. Doxorubicin is in a class of medications called anthracyclines. Doxorubicin damages the cell's DNA and may kill tumor cells. It also blocks a certain enzyme needed for cell division and DNA repair. Topotecan is in a class of medications called topoisomerase I inhibitors. It works by interfering with tumor cell DNA which kills them. Giving topotecan in addition to standard IVADo and IVA chemotherapy regimens may shrink the cancer as well as or better than the standard therapy or could decrease the chance the tumor spreads while causing fewer side effects.

Triptorelin for the Prevention of Ovarian Damage in Adolescents and Young Adults With Cancer

This phase III trial compares the effect of giving triptorelin vs no triptorelin in preventing ovarian damage in adolescents and young adults (AYAs) with cancer receiving chemotherapy with an alkylating agents. Alkylating agents are part of standard chemotherapy, but may cause damage to the ovaries. If the ovaries are not working well or completely shut down, then it will be difficult or impossible to get pregnant in the future. Triptorelin works by blocking certain hormones and causing the ovaries to slow down or pause normal activity. The triptorelin used in this study stays active in the body for 24 weeks or about 6 months after a dose is given. After triptorelin is cleared from the body, the ovaries resume normal activities. Adding triptorelin before the start of chemotherapy treatment may reduce the chances of damage to the ovaries.

Registry for Stage 2 Type 1 Diabetes

Stage 2 Type 1 Diabates (T1D) is an early stage of T1D characterized by dysglycemia but not yet leading to clinical symptoms. Progression of the disease to Stage 3 (clinical T1D), leads to overt hyperglycemia requiring eventually exogenous insulin. TZIELD® (teplizumab-mzwv) has been approved to delay onset of stage 3 T1D, by the United States (US) Food and Drug Administration (FDA) for adults and children aged 8 years and older with Stage 2 T1D. The purpose of this study is to collect general information on patients with stage 2 T1D and further information on the long-term effects of TZIELD® in patients with Stage 2 T1D, treated as per standard of care.

Bionic Pancreas in CFRD

This multi-center randomized controlled trial (RCT) will compare efficacy and safety endpoints using the insulin-only configuration of the iLet Bionic Pancreas System (BP) versus a control group using their usual care insulin delivery method and continuous glucose monitoring (CGM) during a 13-week study period in individuals ≥14 years old with cystic fibrosis-related diabetes (CFRD). After 13 weeks, participants will continue in a 13-week Extension Phase in which the BP group will continue to use the BP system and the Usual Care group will initiate use of the BP system.

Testing the Addition of the Anti-cancer Drug Venetoclax and/or the Anti-cancer Immunotherapy Blinatumomab to the Usual Chemotherapy Treatment for Infants With Newly Diagnosed KMT2A-rearranged or KMT2A-non-rearranged Leukemia

This phase II trial tests the addition of venetoclax and/or blinatumomab to usual chemotherapy for treating infants with newly diagnosed acute lymphoblastic leukemia (ALL) with a KMT2A gene rearrangement (KMT2A-rearranged \[R\]) or without a KMT2A gene rearrangement (KMT2A-germline \[G\]). Venetoclax is in a class of medications called B-cell lymphoma-2 (Bcl-2) inhibitors. It may stop the growth of cancer cells by blocking Bcl-2, a protein needed for cancer cell survival. Blinatumomab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. Chemotherapy drugs 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. Adding venetoclax and/or blinatumomab to standard chemotherapy may be more effective at treating patients with ALL than standard chemotherapy alone, but it may also cause more side effects. This clinical trial evaluates the safety and effectiveness of adding venetoclax and/or blinatumomab to chemotherapy for the treatment of infants with KMT2A-R or KMT2A-G ALL.

Dinutuximab With Chemotherapy, Surgery and Stem Cell Transplantation for the Treatment of Children With Newly Diagnosed High Risk Neuroblastoma

This phase III trial tests how well the addition of dinutuximab to Induction chemotherapy along with standard of care surgical resection of the primary tumor, radiation, stem cell transplantation, and immunotherapy works for treating children with newly diagnosed high-risk neuroblastoma. Dinutuximab is a monoclonal antibody that binds to a molecule called GD2, which is found on the surface of neuroblastoma cells, but is not present on many healthy or normal cells in the body. When dinutuximab binds to the neuroblastoma cells, it helps signal the immune system to kill the tumor cells. This helps the cells of the immune system kill the cancer cells, this is a type of immunotherapy. When chemotherapy and immunotherapy are given together, during the same treatment cycle, it is called chemoimmunotherapy. This clinical trial randomly assigns patients to receive either standard chemotherapy and surgery or chemoimmunotherapy (chemotherapy plus dinutuximab) and surgery during Induction therapy. Chemotherapy drugs administered during Induction include, cyclophosphamide, topotecan, cisplatin, etoposide, vincristine, and doxorubicin. These drugs 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. Upon completion of 5 cycles of Induction therapy, a disease evaluation is completed to determine how well the treatment worked. If the tumor responds to therapy, patients receive a tandem transplantation with stem cell rescue. If the tumor has little improvement or worsens, patients receive chemoimmunotherapy on Extended Induction. During Extended Induction, dinutuximab is given with irinotecan, temozolomide. Patients with a good response to therapy move on to Consolidation therapy, when very high doses of chemotherapy are given at two separate points to kill any remaining cancer cells. Following, transplant, radiation therapy is given to the site where the cancer originated (primary site) and to any other areas that are still active at the end of Induction. The final stage of therapy is Post-Consolidation. During Post-Consolidation, dinutuximab is given with isotretinoin, with the goal of maintaining the response achieved with the previous therapy. Adding dinutuximab to Induction chemotherapy along with standard of care surgical resection of the primary tumor, radiation, stem cell transplantation, and immunotherapy may be better at treating children with newly diagnosed high-risk neuroblastoma.

Study of Revumenib, Azacitidine, and Venetoclax in Pediatric and Young Adult Patients With Refractory or Relapsed Acute Myeloid Leukemia

This is a research study to find out if adding a new study drug called revumenib to commonly used chemotherapy drugs is safe and if they have beneficial effects in treating patients with acute myeloid leukemia (AML) or acute leukemia of ambiguous lineage (ALAL) that did not go into remission after treatment (refractory) or has come back after treatment (relapsed), and to determine the total dose of the 3-drug combination of revumenib, azacitidine and venetoclax that can be given safely in participants also taking an anti-fungal drug. Primary Objective * To determine the safety and tolerability of revumenib + azacitidine + venetoclax in pediatric patients with relapsed or refractory AML or ALAL. Secondary Objectives * Describe the rates of complete remission (CR), complete remission with incomplete count recovery (CRi), and overall survival for patients treated with revumenib + azacitidine + venetoclax at the recommended phase 2 dose (RP2D).

A Safety Assessment of Oral Letermovir in Infants With Symptomatic Congenital Cytomegalovirus

This is a Phase 1 single-arm open-label study of letermovir in neonates with symptomatic congenital Cytomegalovirus (CMV) disease. There will be two groups enrolled. Group 1 will be comprised of 4 subjects. Following documentation study inclusion and signing of informed consent, Group 1 subjects will receive one dose of oral letermovir (Study Day 0), using the dose bands. A full pharmacokinetics (PK) profile will then be obtained over the next 24 hours, and blood specimens will be shipped immediately to the University of Alabama at Birmingham (UAB) Pharmacokinetic Lab and processed in real time. Within = 7 days, pharmacokinetics (PK) results will be conveyed to the study site. If the Area Under the Curve (AUC24) is =100,000 ngxhr/mL (see footnote a in Table 1), the subject will initiate a 14-day course of once-daily oral letermovir at the same dose as utilized on Dose Finding Day. This duration of letermovir therapy was selected based upon our earlier observation in this population that patients with symptomatic congenital Cytomegalovirus (CMV) disease who achieve viral suppression to =2.5 log by day 14 of valganciclovir therapy and then maintain it over the next 4 months are statistically more likely to have improved hearing across the first two years of life (22). If the observed letermovir exposure of the subject is \> 100,000 ngxhr/mL, the once-daily oral letermovir dose that will be used will be adjusted down in 2.5 mg increments. Oral valganciclovir (16 mg/kg/dose BID) will begin within the first month of life, as standard of care; initiation of valganciclovir can be concomitant with or prior to initiation of the 14-day course of letermovir (but will not start before obtaining the pharmacokinetics (PK) specimens following the single dose of letermovir on the Dose Finding Day). This is similar to the intensification approach that has been evaluated in the management of patients infected with human immunodeficiency virus (23-25). The day that the 14-day course of letermovir begins for Group 1 subjects will be known as Study Day 1. Serial blood samples will be obtained on Study Days 1, 5, 10, and 14 for safety chemistry and hematology labs and for Cytomegalovirus (CMV) viral loads. Cytomegalovirus (CMV) viral load will be followed as well on Study Days 21 and 42 to assess for rebound in Cytomegalovirus (CMV) following cessation of letermovir treatment on Study Day 14. Saliva and urine viral loads will be followed at these timepoint as well. Full pharmacokinetics (PK) profiles for both letermovir and ganciclovir will be obtained on Study Day 10. In addition, sparse pharmacokinetics (PK) sampling will be obtained on Study Days 1, 5, and 14. Adverse events will be assessed at each study visit during treatment, and at Study Days 21 and 42 (4 weeks after the last study drug dose). Subjects then will continue on oral valganciclovir as routine clinical care to complete an anticipated 6 month duration of total therapy. The primary Objective is to determine the systemic exposure (AUC24) of letermovir following administration of oral letermovir granules in infants with symptomatic congenital CMV disease.

A Study Using Nivolumab, in Combination With Chemotherapy Drugs to Treat Nasopharyngeal Carcinoma (NPC)

This phase II trial tests effects of nivolumab in combination with chemotherapy drugs prior to radiation therapy patients with nasopharyngeal carcinoma (NPC). Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as gemcitabine and cisplatin, 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. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. Researchers want to find out what effects, good and/or bad, adding nivolumab to chemotherapy has on patients with newly diagnosed NPC. In addition, they want to find out if children with NPC may be treated with less radiation therapy and whether this decreases the side effects of therapy.

Optimization of Saturation Targets And Resuscitation Trial (OptiSTART) (OptiSTART)

This study is designed to answer one of the fundamental gaps in knowledge in the resuscitation of preterm infants at birth: What is the optimal target oxygen saturation (SpO2) range that increases survival without long-term morbidities? Oxygen (O2) is routinely used for the stabilization of preterm infants in the delivery room (DR), but its use is linked with mortality and several morbidities including bronchopulmonary dysplasia (BPD). To balance the need to give sufficient O2 to correct hypoxia and avoid excess O2, the neonatal resuscitation program (NRP) recommends initiating preterm resuscitation with low (≤ 30%) inspired O2 concentration (FiO2) and subsequent titration to achieve a specified target SpO2 range. These SpO2 targets are based on approximated 50th percentile SpO2 (Sat50) observed in healthy term infants. However, the optimal SpO2 targets remain undefined in the preterm infants. Recent data suggest that the current SpO2 targets (Sat50) may be too low. The investigators plan to conduct a multicenter RCT of Sat75 versus Sat50 powered for survival without BPD. The investigators will randomize 700 infants, 23 0/7- 30 6/7 weeks' GA, to 75th percentile SpO2 goals (Sat75, Intervention) or 50th percentile SpO2 goals (Sat50, control). Except for the SpO2 targets, all resuscitations will follow NRP guidelines including an initial FiO2 of 0.3. In Aim 1, the investigators will determine whether targeting Sat75 compared to Sat50 increases survival without lung disease (BPD). In addition, the investigators will compare the rates of other major morbidities such as IVH. In Aim 2, the investigators will determine whether targeting Sat75 compared to Sat50 increases survival without neurodevelopmental impairment at 2 years of age. In Aim 3, the investigators will determine whether targeting Sat75 compared to Sat50 decreases oxidative stress.
