Quick Navigation

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

To learn if pentoxifylline and vitamin E or pravastatin can reduce radiation-induced lymphedema/fibrosis.

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.

Ages Eligible for Study:18 Years

Sexes Eligible for Study:ALL

Accepts Healthy Volunteers:No

Standard Ages:ADULT, OLDER_ADULT

Inclusion Criteria	Exclusion Criteria
1. Dispositioned to radiotherapy with prescribed dose to unilateral or bilateral neck(s). 2. Creatinine clearance \>30mL/min 3. Age ≥18 years. Because no dosing or adverse event data are currently available on the use of pentoxifylline/pravastatin in participants \<18 years of age, children are excluded from this study 4. ECOG performance status ≤2 (Karnofsky ≥60%,) 5. Participants must have adequate organ and marrow function as defined below * absolute neutrophil count ≥1,000/mcL * platelets ≥100,000/mcL * total bilirubin ≤ institutional upper limit of normal (ULN) * AST(SGOT)/ALT(SGPT) ≤3 x institutional ULN * creatinine ≤1.5 x institutional ULN 6. The effects of pentoxifylline/pravastatin on the developing human fetus are unknown. For this reason, women of child-bearing potential must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. (Refer to Pregnancy Assessment Policy MD Anderson Institutional Policy # CLN1114). This includes all female participants, between the onset of menses (as early as 8 years of age) and 55 years unless the patient presents with an applicable exclusionary factor which may be one of the following. * Postmenopausal (no menses in greater than or equal to 12 consecutive months). * History of hysterectomy or bilateral salpingo-oophorectomy. * Ovarian failure (Follicle Stimulating Hormone and Estradiol in menopausal range, who have received Whole Pelvic Radiation Therapy). * History of bilateral tubal ligation or another surgical sterilization procedure. * Approved methods of birth control are as follows: Hormonal contraception (i.e. birth control pills, injection, implant, transdermal patch, vaginal ring), Intrauterine device (IUD), Tubal Ligation or hysterectomy, Subject/Partner post vasectomy, Implantable or injectable contraceptives, and condoms plus spermicide. Not engaging in sexual activity for the total duration of the trial and the drug washout period is an acceptable practice; however periodic abstinence, the rhythm method, and the withdrawal method are not acceptable methods of birth control. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately. 7. Ability to understand and the willingness to sign a written informed consent document.	1. Active liver disease (Child-Pugh class B-C), cirrhosis, nor active alcoholism. 2. History of myopathy/rhabdomyolysis. 3. History of acute myocardial infarction or severe coronary disease. 4. Pregnant/post-menopausal, or male. 5. History of diabetes mellitus. 6. Allergy/hypersensitivity to Hydroxymethylglutaryl-coenzyme A (HMG Co-A) reductase inhibitor and/or xanthine derivatives, e.g., caffeine, theophylline, theobromine. 7. Contraindications for MRI 8. Participants who are receiving any other investigational agents. 9. History of allergic reactions attributed to compounds of similar chemical or biologic composition to statins, hemorheologic agents or other agents used in study 10. Participants with psychiatric illness/social situations that would limit compliance with study requirements.
