A Phase 3, randomized, double-blind, placebo-controlled, multicenter study of mavorixafor in participants with congenital and acquired primary autoimmune and idiopathic chronic neutropenic disorders who are experiencing recurrent and/or serious infections

Pediatrics Immunology Autoimmune Pediatric Subjects Adult Subjects

The purpose of this study is to demonstrate the efficacy and evaluate the safety, and tolerability of mavorixafor in participants with congenital or acquired primary autoimmune and idiopathic chronic neutropenic disorders who are experiencing recurrent and/or serious infections as assessed by demonstrating its clinical benefit and increasing levels of circulating neutrophils.

ACNS2321: A Phase II Trial Evaluating Chemotherapy followed by Response-Based Reduced Radiation Therapy for Patients with Central Nervous System Germinomas

Cancer Pediatrics Neurology Heart and Vascular Stroke Vascular Disease Pediatric Subjects Adult Subjects

This phase II trial studies how well lower dose radiotherapy after chemotherapy (Carboplatin \& Etoposide) works in treating children with central nervous system (CNS) germinomas. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. Carboplatin is in a class of medications known as platinum-containing compounds. It works in a way similar to the anticancer drug cisplatin, but may be better tolerated than cisplatin. Carboplatin works by killing, stopping or slowing the growth of tumor cells. Etoposide is in a class of medications known as podophyllotoxin derivatives. It blocks a certain enzyme needed for cell division and DNA repair and may kill cancer cells. Researchers want to see if lowering the dose of standard radiotherapy (RT) after chemotherapy can help get rid of CNS germinomas with fewer long-term side effects.

The purpose of this study is to determine efficacy of guanfacine immediate release (GIR) for the treatment of hyperactivity/impulsivity and inattention in children 6-12 years of age with Down syndrome (DS) after 8 weeks of treatment.

Phase 1/2 Dose Determination and Dose Expansion Study of Cobolimab in Combination with Dostarlimab in Pediatric and Young Adult Participants with Newly Diagnosed and Relapsed/Refractory Tumors (POPSTAR)

Cancer Pediatrics Pediatric Subjects Adult Subjects

The goal of this interventional study is to determine the strength of cobolimab and dostarlimab that is most tolerated in children and young adults who have advanced solid tumors. This study also aims: (a) to check if it is safe to use cobolimab and dostarlimab combination in children and young adults, (b) to see how to manage the side effects that may occur, and (c) the effect of this treatment in participants

ACCL1932: Letermovir Prophylaxis for Cytomegalovirus in Pediatric Hematopoietic Cell Transplantation

Cancer Pediatrics Nephrology Infectious Disease Kidney Disease Infectious Disease Kidney Failure Pediatric Subjects

This phase III trial determines whether taking prophylactic letermovir will reduce the likelihood of infection with cytomegalovirus (CMV) in children and adolescents after stem cell transplant. The treatments used to prepare for HCT reduce the body's natural infection-fighting ability and increase the likelihood of an infection with a virus called cytomegalovirus. "Prophylaxis" means to take a drug to prevent a disease or side effect. Letermovir is an antiviral drug that stops cytomegalovirus from multiplying and may prevent cytomegalovirus infection and make the disease less severe.

Cancer Pediatrics Leukemia Lymphoma Sarcoma Brain and Spinal Cord Cancer Pediatric Subjects Adult Subjects

Substudy 01A is part of a platform study. The purpose of this study is to assess the efficacy and safety of zilovertamab vedotin in pediatric participants with relapsed or refractory B-cell acute lymphoblastic leukemia (B-ALL), diffuse large B-cell lymphoma (DLBCL)/Burkitt lymphoma, or neuroblastoma and in pediatric and young adult participants with Ewing sarcoma.
