Study Evaluating Safety and Efficacy of JCAR017 in Subjects With Relapsed or Refractory Chronic Lymphocytic Leukemia (CLL) or Small Lymphocytic Lymphoma (SLL)
This is a Phase 1/2, open-label, multicenter study to determine the efficacy and safety of JCAR017 in adult subjects with relapsed or refractory CLL or SLL. The study will include a Phase 1 part to determine the recommended dose of JCAR017 monotherapy in subjects with relapsed or refractory CLL or SLL, followed by a Phase 2 part to further assess the efficacy and safety of JCAR017 monotherapy treatment at the recommended dose. A separate Phase 1 cohort will assess the combination of JCAR017 and concurrent ibrutinib. Another separate Phase 1 cohort will assess the combination of JCAR017 and concurrent venetoclax. In all subjects, the safety, efficacy, and pharmacokinetics (PK) of JCAR017 will be evaluated.

Safety Study of Cord Blood Units for Stem Cell Transplants
Background: - Cord blood is blood that is taken from the umbilical cord and placenta of healthy newborns after childbirth. The cord blood collected from a baby is called a cord blood unit. Cord blood units are stored frozen in public cord blood banks. About 10,000 cord blood transplants have been performed in children and adults for blood cancers and other diseases in the world. These transplants have helped save lives and improve treatments. However, not all available units of cord blood have been collected, stored, and licensed according to specific government requirements. These unlicensed units can still be used in transplant, but they can only be given as part of specific research studies. This study will evaluate the safety of giving these unlicensed units by recording any problems that may occur during and after giving the cord blood. Objectives: - To test the safety and effectiveness of unlicensed cord blood units in people who need stem cell transplants. Eligibility: - Individuals who are scheduled to have a stem cell transplant. Design: - Participants will be screened with a medical history and physical exam. - Participants will receive the cord blood unit as part of their stem cell transplant procedure. The transplant will be performed according to the current standard of care for the procedure. - After the transplant, participants will be monitored for up to 1 year. Any problems or side effects from the transplant will be treated as necessary. All outcomes will be reported to the National Cord Blood Program and to the Center for International Blood and Marrow Transplant.

Tagraxofusp in Pediatric Patients With Relapsed or Refractory CD123 Expressing Hematologic Malignancies
Tagraxofusp is a protein-drug conjugate consisting of a diphtheria toxin redirected to target CD123 has been approved for treatment in pediatric and adult patients with blastic plasmacytoid dendritic cell neoplasm (BPDCN). This trial aims to examine the safety of this novel agent in pediatric patients with relapsed/refractory hematologic malignancies. The mechanism by which tagraxofusp kills cells is distinct from that of conventional chemotherapy. Tagraxofusp directly targets CD123 that is present on tumor cells, but is expressed at lower or levels or absent on normal hematopoietic stem cells. Tagraxofusp also utilizes a payload that is not cell cycle dependent, making it effective against both highly proliferative tumor cells and also quiescent tumor cells. The rationale for clinical development of tagraxofusp for pediatric patients with hematologic malignancies is based on the ubiquitous and high expression of CD123 on many of these diseases, as well as the highly potent preclinical activity and robust clinical responsiveness in adults observed to date. This trial includes two parts: a monotherapy phase and a combination chemotherapy phase. This design will provide further monotherapy safety data and confirm the FDA approved pediatric dose, as well as provide safety data when combined with chemotherapy. The goal of this study is to improve survival rates in children and young adults with relapsed hematological malignancies, determine the recommended phase 2 dose (RP2D) of tagraxofusp given alone and in combination with chemotherapy, as well as to describe the toxicities, pharmacokinetics, and pharmacodynamic properties of tagraxofusp in pediatric patients. About 54 children and young adults will participate in this study. Patients with Down syndrome will be included in part 1 of the study.

• Immunotherapy: At least 30 days from last infusion of chimeric antigen receptor T cell (CART) therapy or tumor vaccine.
• XRT: Craniospinal XRT is prohibited during protocol therapy. No washout period is necessary for radiation given to any extramedullary site other than CNS chloromas; ≥ 90 days must have elapsed if prior TBI or craniospinal XRT.
• Patients that have received other non-tagraxofusp CD123 targeting agents are eligible. Patients that have previously received tagraxofusp are not eligible. Organ Function Requirements Adequate Bone Marrow Function Defined as:
• Patients should not be known to be refractory to red blood cell or platelet transfusions.
• Blood counts are not required to be normal prior to enrollment on trial. However, platelet count must be ≥20,000/mm3 to initiate therapy (may receive platelet transfusions). Adequate Renal Function Defined as:
• Patient must have a calculated creatinine clearance or radioisotope GFR ≥ 70ml/min/1.73m2 OR a normal serum creatinine based on age/gender in the chart below: Maximum Serum Creatinine (mg/dL):
• 1 to < 2 years old - Male: 0.6, Female: 0.6
• 2 to < 6 years old - Male:0.8, Female: 0.8
• 6 to < 10 years old - Male: 1, Female: 1
• 10 to < 13 years old - Male: 1.2, Female: 1.2
• 13 to < 16 years old - Male: 1.5, Female: 1.4
• ≥ 16 years old - Male: 1.7, Female: 1.4 The threshold creatinine values in this Table were derived from the Schwartz formula for estimating GFR (Schwartz et al. J. Peds, 106:522, 1985) utilizing child length and stature data published by the CDC. Adequate Liver Function Defined as:
• Total bilirubin (sum of conjugated + unconjugated) ≤ 1.5 x institutional upper limit of normal for age
• SGPT (ALT) and SGOT (AST) must be less than 3x institutional upper limit of normal.
• Serum albumin ≥3.2 g/dL (albumin infusion independent). Adequate Cardiac Function Defined as:
• Shortening fraction of ≥27% by echocardiogram, or
• Ejection fraction of ≥ 50% by gated radionuclide study/echocardiogram. Adequate Pulmonary Function Defined as:
• Pulse oximetry > 94% on room air (> 90% if at high altitude)
• No evidence of dyspnea at rest and no exercise intolerance. Reproductive Function
• Female patients of childbearing potential must have a negative urine or serum pregnancy test confirmed within 2 weeks prior to enrollment.
• Female patients with infants must agree not to breastfeed their infants while on this study.
• Male and female patients of child-bearing potential must agree to use an effective method of contraception approved by the investigator during the study and for 12 weeks after the last dose of tagraxofusp. Exclusion Criteria Disease Status:
• Patients with CNS disease are not eligible for Part 1.
• Patients with isolated CNS disease are not eligible for Part 1 or Part 2.
• Patients with isolated non-CNS disease are eligible for Part 1 and Part 2. Concomitant Medications
• Corticosteroids - Patients receiving corticosteroids for disease control who have not been on a stable or decreasing dose of corticosteroid for at least 7 days prior to enrollment are not eligible.
• Investigational Drugs - Patients who are currently receiving another investigational drug are not eligible. The definition of "investigational" for use in this protocol means any drug that is not licensed by the FDA, Health Canada or the Therapeutic Goods Administration to be sold in the countries they govern. (United States, Canada and Australia)
• Anti-cancer Agents - Patients who are currently receiving or may receive while on therapy, other anti-cancer agents, radiation therapy or immunotherapy are not eligible [except hydroxyurea, which may be continued until 24 hours prior to start of protocol therapy]. Intrathecal chemotherapy (at the discretion of the primary oncologist) may be given up to one week prior to the initiation of study treatment (day 1 therapy).
• Anti-GVHD or agents to prevent organ rejection post-transplant - Patients who are receiving cyclosporine, tacrolimus or other agents to prevent either graft-versus-host disease post bone marrow transplant or organ rejection post-transplant are not eligible for this trial. At least 4 weeks must have elapsed after the last dose of GVHD meds. Infection Criteria - Patients are excluded if they have:
• Positive blood culture within 48 hours of study enrollment;
• Fever above 38.2 within 48 hours of study enrollment with clinical signs of infection. Fever that is determined to be due to tumor burden is allowed if patients have documented negative blood cultures for at least 48 hours prior to enrollment and no concurrent signs or symptoms of active infection or hemodynamic instability.
• A positive fungal culture within 30 days of study enrollment.
• Active fungal, viral, bacterial, or protozoal infection requiring IV treatment. Chronic prophylaxis therapy to prevent infections is allowed.
• Patients will be excluded if they have a known allergy to any of the drugs used in the study.
• Patients will be excluded if they have significant concurrent disease, illness, psychiatric disorder or social issue that would compromise patient safety or compliance with the protocol treatment or procedures, interfere with consent, study participation, follow up, or interpretation of study results.
• Patients with DNA fragility syndromes (such as Fanconi anemia, Bloom syndrome) are excluded.
