Phase phase 2
Sponsor Mara Chambers
Start date September 2010
End date December 2014
Trial size 40 participants
Trial identifier NCT01205503, 10-0431-F1V


The purpose of this study is to determine whether the drug mesna is able to block a series of chemical changes that occur in the blood of patients who receive the chemotherapy medicine doxorubicin. The researchers believe these blood chemical changes may the cause of "cloudy thinking" or "chemobrain" that are reported by some patients receiving chemotherapy

Primary Outcomes

Plasma protein oxidation and TNF-α levels in patients receiving doxorubicin containing chemotherapy
time frame: prior to and 3 hours post doxorubicin

Eligibility Criteria

Male or female participants at least 18 years old.

Inclusion Criteria: Participants must have histologically or cytologically confirmed breast cancer or non-hodgkin lymphoma and independent of protocol eligibility be determined to require one of the chemotherapy regimens listed below Participants must require as standard-of-care treatment a chemotherapy regimen that includes one of the following combinations: - doxorubicin 60 mg/m2 and cyclophosphamide 600 mg/m2; - doxorubicin 50 mg/m2, cyclophosphamide 500 mg/m2, and docetaxel 75 mg/m2; - doxorubicin 50 mg/m2, cyclophosphamide 750 mg/m2, vincristine 1.4 mg/m2 (capped at 2 mg dose), and prednisone 100 mg +/- rituximab 375 mg/m2 Age >18 years.Because these treatment regimens are rarely used in pediatric oncology, children are excluded from this study but will be eligible for future pediatric phase 2 trials. Life expectancy of greater than 6 months. Zubrod performance status 2 or better. Patients must have normal organ and marrow function as defined below: - leukocytes >3,000/mcL (unless due to cancer in marrow) - absoluteneutrophil count >1,500/mcL (unless due to cancer in marrow) - platelets >100,000/mcL (unless due to cancer in marrow) - total bilirubin <1.5 X normal institutional limits - AST(SGOT)/ALT(SGPT) <2.5 X institutional upper limit of normal - creatinine within normal institutional limits OR - creatinine clearance >60 mL/min/1.73 m2 for patients with creatinine levels above institutional normal - left ventricular function ≥ 50 % ejection fraction Because the standard of care chemotherapy agents are known to be teratogenic, women of child-bearing potential and men 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. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately. Ability to understand and the willingness to sign a written informed consent document. Exclusion Criteria: Patients who have had chemotherapy or radiotherapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study or those who have not recovered from adverse events due to agents administered more than 4 weeks earlier. Patients may not be receiving any other investigational agents Patients with known brain metastases should be excluded from this clinical trial because progressive neurologic dysfunction would confound the evaluation of neuro-cognitive outcomes. History of allergic reactions attributed to compounds of similar chemical or biologic composition to mesna or other agents used in the study (ie. sulfur containing drugs including "sulfa antibiotics" and celecoxib). Patients requiring ongoing pharmacologic treatment of dementia are excluded. Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements. Pregnant women are excluded from this study because the chemotherapy agents have known teratogenic or abortifacient effects. Because there is a potential risk for adverse events in nursing infants secondary to treatment of the mother with chemotherapy, breastfeeding should be discontinued if the mother is treated with chemotherapy. HIV-positivity is NOT a specific exclusion criteria.

Additional Information

Official title Randomized, Blinded Trial of Mesna to Prevent Doxorubicin-induced Plasma Protein Oxidation and TNF-α Release
Principal investigator Mara Chambers, M.D.
Description Patients with lymphoma and breast cancer receiving chemotherapy regimens that include anthracycline drugs, such as doxorubicin, are at risk for developing cognitive and cardiac impairment. This potential cognitive impairment is refered to as "chemobrain" by some patients. We have demonstrated in mice that the drug mesna, which is used to prevent other complications of other chemotherapy drugs, prevents certain types of doxorubicin-induced damage of blood proteins. Blocking doxorubicin's damage of these blood proteins has blunted or prevented the subsequent markers of neurologic and cardiac injury in mice. This clinical trial will determine if mesna prevents doxorubicin-induced damage of blood proteins in cancer patients, and may establish if blood protein injury is the first step in anthracycline-induced cognitive and cardiac dysfunction and if using the drug mesna can blunt or prevent these changes in blood markers of injury for patients with cancer.
