Trial Information

Phase III, Randomized, Study of Sulfasalazine Versus Placebo in the Prevention of Acute Diarrhea in Patients Receiving Pelvic Radiation Therapy


OBJECTIVES:

Primary

- To determine whether sulfasalazine is effective in reducing the acute treatment-related
diarrhea in patients receiving pelvic radiotherapy as measured by NCI CTC v4.0 in
patients receiving pelvic external-beam radiotherapy as adjuvant or primary treatment
for malignancy.

Secondary

- To determine whether sulfasalazine can reduce chronic treatment-related bowel
dysfunction following completion of therapy.

- To determine whether sulfasalazine causes any toxicity in this situation.

Tertiary

- To bank blood products for future studies, as part of ongoing research for NCCTG
studies (Mayo Clinic Rochester only). (Translational)

OUTLINE: This is a multicenter study. Patients are stratified according to history of
anterior resection of the rectum (yes vs no); total planned cumulative dosing, including
boost fields of external-beam radiotherapy (4500-5350 cGy vs > 5350 cGy); and concurrent
radiosensitizing fluorouracil, capecitabine, or oxaliplatin (yes vs no). Patients are
randomized to 1 of 2 treatment arms.

- Arm I: Patients receive oral sulfasalazine twice daily during radiotherapy* and for 4
weeks after completion of radiotherapy.

- Arm II: Patients receive oral placebo twice daily during radiotherapy* and for 4 weeks
after completion of radiotherapy.

NOTE: *Patients must start study treatment by the third radiotherapy fraction.

Patients may undergo blood sample collection at baseline and then weekly during
radiotherapy. All patients complete quality of life and bowel function questionnaires at
baseline, weekly during radiotherapy, and at 6 weeks after completion of radiotherapy.

After completion of radiotherapy, patients are followed up at 6 weeks and at 12 and 24
months.

Inclusion Criteria


DISEASE CHARACTERISTICS:

- Diagnosis of cancer that supports the use of radiotherapy to the pelvis

- No current or prior metastases beyond pelvic regional lymph nodes

- Planning to receive a course of continuous definitive or adjuvant external-beam
radiotherapy to a minimum dose of 4500 cGy with or without fluorouracil,
capecitabine, or oxaliplatin

- Planned course of pelvic radiotherapy must fall within the following parameters:

- Pelvis must be encompassed by the planned radiotherapy fields

- Superior border may not lie superior to the L4-5 interspace and may not be
inferior to the most inferior aspect of the sacroiliac joints

- Portions of the rectum may have special blocking, depending upon disease
site

- Total planned dose to the central axis midplane (for AP-PA parallel opposed
fields) or isocenter (for 3- or 4-field techniques) for the pelvic field must
lie between 4500-5300 cGy (inclusive)*

- Subsequent to completion of treatment to the pelvic field, a boost to
primary tumor or tumor bed may be planned

- Planned treatment is to be given 4-5 times per week on a one-treatment-per-day
basis

- Daily dose (specified at central axis midplane or at isocenter for
multi-field techniques) must lie between 170-210 cGy (inclusive) per day*

- NOTE: *For institutions that do not use midplane or isocenter as the point for
specification of dose, it will be necessary to determine the dose according to the
methods specified above in order to determine patient eligibility.

- No perineal irradiation planned (e.g., anal cancer patients, patients who have had an
abdominal-perineal resection)

- No brachytherapy planned before the completion of all external-beam radiotherapy

- No planned split-course radiotherapy

- AST ≤ 1.5 times ULN

- Not pregnant or nursing

- Negative pregnancy test

- Fertile patients must use effective contraception

- Willing to provide blood specimens as required by the study (Mayo Clinic Rochester
patients only)

component of drug formulation

PRIOR CONCURRENT THERAPY:

- See Disease Characteristics

- No prior pelvic radiotherapy

- No prior abdominal-perineal resection, Hartmann procedure, or other surgical
procedure leaving the patient without a functioning rectum

- No planned use of leucovorin or cytotoxic chemotherapeutic agents concurrent with
radiotherapy (except for fluorouracil, capecitabine, or oxaliplatin)

- No other concurrent sulfasalazine

- No concurrent digoxin
