TBI Using IMRT and Cyclophosphamide Prior to Stem Cell Transplant for the Treatment of Severe Systemic Sclerosis

Description

This early phase I trial studies the side effects and feasibility of total body irradiation using intensity modulation radiation therapy (IMRT) when given in combination with cyclophosphamide prior to stem cell transplant to treat severe systemic sclerosis. IMRT delivers total body radiation therapy more precisely and may reduce radiation exposure to sensitive normal organs. Giving chemotherapy, such as cyclophosphamide, and total body irradiation before a donor stem cell transplant helps kill cancer cells in the body and helps make room in the bone marrow for new blood-forming cells (stem cells) to grow. Giving IMRT and cyclophosphamide prior to stem cell transplant may work better in treating severe systemic sclerosis and reduce radiation doses to lung and kidneys compared to cyclophosphamide alone.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

For general information about clinical research, read Learn About Studies.

Eligibility Criteria

  • * Karnofsky performance status (KPS) \>= 70
  • * Systemic sclerosis patients evaluated within 30 days of start of conditioning regimen who would be candidates for TBI-cyclophosphamide (Cy) per City of Hope (COH) guidelines and standard operating procedures (SOP) for autologous hematopoietic cell transplant
  • * Patients must be suitable for TBI conditioning regimens as part of transplant per radiation the referring hematologist
  • * Patients must have adequate organ function for HCT as determined by the hematologist
  • * Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control or abstinence) prior to study entry and for six months following duration of study participation
  • * All subjects must have the ability to understand the treatment and the willingness to sign a written informed consent
  • * Patients should not have any uncontrolled illness including ongoing or active infection
  • * Prior history of radiation therapy must be presented to study principal investigator (PI) for eligibility determination
  • * Pregnant women are excluded from this study because total body irradiation is an agent with the potential for teratogenic or abortifacient effects
  • * Subjects, who in the opinion of the investigator, may not be able to comply with the safety monitoring requirements of the study
