Summary

This phase I trial studies the side effects and best dose of trametinib when given together with fluorouracil and radiation therapy before surgery in treating patients with stage II-III rectal cancer. Trametinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as fluorouracil, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving trametinib together with fluorouracil and radiation therapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed

Conditions

  • Recurrent Rectal Cancer
  • Stage IIA Rectal Cancer
  • Stage IIB Rectal Cancer
  • Stage IIC Rectal Cancer
  • Stage IIIA Rectal Cancer
  • Stage IIIB Rectal Cancer
  • Stage IIIC Rectal Cancer

Interventions

DRUG

trametinib

Trametinib will be given for 5-day lead-in period by mouth daily Monday-Friday starting at day -14 through -10 and concurrently for the duration of radiation therapy (approximately days 1-38).The dose of Trametinib will be escalated: 0.5 mg, 1.0 mg, 2mg. If the 2 mg dose level causes DLT (dose-limiting toxicity)in 2 out of 6 patients and the 1mg dose level was acceptable, then a 1.5 mg dose cohort will be used.

DRUG

fluorouracil

Will be administered as a continuous infusion over 120 hours at a dose of 225 mg/m2/day on Monday to Friday of every week starting day 1-38.

RADIATION

radiation therapy

Radiation therapy will be delivered to the pelvis during (approximately) days 1-33 (five days a week, Mondays through Fridays for 25 fractions) using a 3-field or 4-field 3-D conformal plan to the primary tumor, surrounding soft tissues, and at risk lymph node stations (peri-rectal, presacral, internal iliac, with or without external iliac) to a total dose of 45 Gy in 1.8 Gy daily fractions. A boost radiation field will be delivered during (approximately) days 36-38. The boost will encompass the primary rectal tumor and involved lymph nodes with a 2-2.5 cm margin, which should include the presacral space. The boost dose will be 5.4 Gy in 1.8 Gy fractions for a total dose of 50.4 Gy.
