Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

This phase I trial tests the side effects and best dose of total marrow lymphoid irradiation along with chemotherapy, with fludarabine and melphalan, with or without thiotepa, in combination with Orca-T cells for patients with acute myeloid leukemia (AML), acute lymphoblastic leukemia (ALL) or myelodysplastic syndrome (MDS). Total marrow and lymphoid irradiation is a targeted form of total body irradiation that uses intensity-modulated radiation therapy to target marrow, lymph node chains, and the spleen. It is designed to reduce radiation-associated side effects and maximize the radiation therapeutic effect. Giving chemotherapy with medications such as thiotepa, fludarabine, and melphalan before a treatment with stem cells helps kill cancer cells in the body and helps make room in the patient's bone marrow for new blood-forming cells (stem cells) to grow. Orca-T cells take cells from a donor and remove some of the T cells and replace them with partially engineered T cells in order to induce better tolerance in patients. Giving total marrow and lymphoid irradiation and chemotherapy followed by Orca -T cells may be an effective treatment for patients with AML, ALL or MDS.

  19. * Serum glutamic oxaloacetic transaminase (SGOT) and serum glutamic pyruvic transaminase (SGPT) ≤ 2.5 times the institutional upper limits of normal performed within 30 days prior to day 1. Patients with Gilberts disease are allowed
  20. * Creatinine clearance of ≥ 60 mL/min per 24 hour urine test or the Cockcroft-Gault formula performed within 30 days prior to day 1
  21. * Ejection fraction measured by echocardiogram or MUGA ≥ 50% performed within 30 days prior to day 1
  22. * If able to perform pulmonary function tests: forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC) and carbon monoxide diffusing capability (DLCO) (diffusion capacity) ≥ 50% of predicted (corrected for hemoglobin).
  23. * Women of childbearing potential (WOCBP): negative urine or serum pregnancy test performed within 30 days prior to day 1. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required
  24. * Agreement by females and males of childbearing potential\* to use an effective method of birth control or abstain from heterosexual activity for the course of the study through at least 6 months after the last dose of protocol therapy.
  25. * Childbearing potential defined as not being surgically sterilized (men and women) or have not been free from menses for \> 1 year (women only)
  26. * PATIENTS: Patients should have discontinued all previous intensive therapy, chemotherapy or radiotherapy for 2 weeks prior to commencing therapy on this study NOTE: Low dose chemotherapy or maintenance chemotherapy given within 7 days of planned study enrollment is permitted. These include hydroxyurea, 6-meraptopurine, oral methotrexate, vincristine, oral etoposide, and tyrosine kinase inhibitors (TKIs). FLT-3 inhibitors can also be given up to 3 days before conditioning regimen.) All patients with prior radiation treatment to the lung, liver, and kidney will be excluded. For other scenarios of prior radiation treatment, up to 2000 cGy at 2 Gy per day will be allowed. Inclusion of patients with previous radiation exposure will be determined based on the radiation oncologist medical doctor (MD) evaluation and judgment
  27. * DONORS: All candidates for this study must have an human leukocyte antigen (HLA) (A, B, C, and DR) identical sibling who is willing to donate mobilized peripheral blood stem cells or have a 10/10 (A, B, C, DR and DQ) allele matched unrelated donor (DQ or DP mismatch is allowed per discretion of the principal investigator), or haploidentical donor. City of Hope (COH) standard operating procedures (SOP) (B.001.11) will be used for allogeneic donor evaluation, selection, and consent. Donor screening will be in compliance with all requirements of Food and Drug Administration (FDA) regulation 21 Code of Federal Regulations (CFR) Part 1271 including donor screening for COVID-19 exposure or infection
  1. * PATIENTS: Prior allogeneic stem cell transplant
  2. * PATIENTS: More than 3 prior lines of intensive chemotherapy, where the regimen intent was to induce remission
  3. * PATIENTS: Receiving any other investigational agents or concurrent biological, intensive chemotherapy or radiation therapy for the previous 2 weeks from conditioning NOTE: Low dose chemotherapy or maintenance chemotherapy given within 7 days of planned study enrollment is permitted. These include: Hydroxyurea, 6-meraptopurine, oral methotrexate, vincristine, oral etoposide, and tyrosine kinase inhibitors (TKIs). FLT-3 inhibitors can also be given up to 3 days before conditioning regimen

Patients with prior history of localized prostate cancer treated with curative intent regardless of time from the treatment to study entry, and patients with prostate cancer receiving active surveillance not requiring therapy are eligible
  7. * PATIENTS: The recipient has a medical problem or neurologic/psychiatric dysfunction which would impair his/her ability to be compliant with the medical regimen and to tolerate transplantation or would prolong hematologic recovery which in the opinion of the principal investigator would place the recipient at unacceptable risk
