Brief 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

Detailed Description:

PRIMARY OBJECTIVES:

I. To identify the maximally tolerated dose and recommended phase II dose of trametinib to be used in combination with 5FU (fluorouracil) and radiation in patients with rectal cancers.

II. To determine a recommended phase II dose of trametinib to be used with 5FU chemoradiation in patients with locally advanced rectal cancer.

SECONDARY OBJECTIVES:

I. Evaluation of the tolerability and safety of the combination of trametinib and 5-FU chemoradiation in locally advanced rectal cancer.

II. Evaluation of post-therapy pathologic response.

III. Evaluation of the rate of local control, disease-free survival and overall survival.

IV. Analysis of biomarkers - total mutations in v-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog (KRAS), v-raf murine sarcoma viral oncogene homolog B1(BRAF), and neuroblastoma RAS viral (v-ras) oncogene homolog (NRAS), as well as RAS/mitogen-activated protein kinase (MAPK) and phosphatidylinositol-4,5-bisphosphate 3-kinase (PI3K)/v-akt murine thymoma viral oncogene homolog 1 (AKT) pathway signaling pathways to potentially correlate with clinical benefit.

OUTLINE: This is a dose-escalation study of trametinib.

Patients receive trametinib orally (PO) once daily (QD) on days -14 to -10 and 1-38 and fluorouracil intravenously (IV) continuously 5 days a week from days 1-38. Patients also undergo radiation therapy 5 days a week on days 1-33. Patients then undergo surgery 6-10 weeks later.

Patients achieving negative surgical margins after complete resection of tumor receive postoperative chemotherapy comprising leucovorin calcium IV over 2 hours and fluorouracil IV continuously over 46 hours on days 1 and 15 OR oxaliplatin IV over 2 hours, leucovorin calcium IV over 2 hours and fluorouracil IV continuously over 46 hours on days 1 and 15. Treatment repeats every 28 days for up to 4 courses in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 3 months for 2 years, and then annually for 3 years.

Arm Intervention/treatment
Experimental: Treatment (trametinib, fluorouracil, radiation, surgery)

Patients receive trametinib PO (by mouth) QD (daily) on days -14 through -10 and 1-38 and fluorouracil IV continuously 5 days a week from days 1-38. Patients also undergo radiation therapy 5 days a week on days 1-33. Patients then undergo surgery 6-10 weeks later.

Patients achieving negative surgical margins after complete resection of tumor receive postoperative chemotherapy comprising leucovorin calcium IV over 2 hours and fluorouracil IV continuously over 46 hours on days 1 and 15 OR oxaliplatin IV over 2 hours, leucovorin calcium IV over 2 hours and fluorouracil IV continuously over 46 hours on days 1 and 15. Treatment repeats every 28 days for up to 4 courses in the absence of disease progression or unacceptable toxicity.

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.
Other Name: GSK1120212

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.
Other Names:
  • 5-fluorouracil
  • 5-Fluracil
  • 5-FU

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.
Other Names:
  • irradiation
  • radiotherapy
  • therapy, radiation




Primary Outcome Measures :
  1. Identify the maximally tolerated dose of Trametinib to be used in combination with 5FU and radiation in patients with rectal cancers. [ Time Frame: up to 9 weeks ]

Secondary Outcome Measures :
  1. Frequency of dose-limiting toxicities, assessed according to the NCI CTCAE version 4 [ Time Frame: up to 9 weeks ]
    The observed adverse events and their grade and attribution for each dose level, and patterns reflecting tolerability of the regimen will be summarized through graphical analysis and descriptive summaries.

  2. Local failure rate [ Time Frame: From the time of study enrollment until the first documented date of local failure, assessed up to 5 years ]
    Will be described graphically and quantitatively using the methods of Kaplan and Meier.

  3. Progression free survival [ Time Frame: From the time of study enrollment until the first documented date of disease progression, assessed up to 5 years ]
    Will be described graphically and quantitatively using the methods of Kaplan and Meier.

  4. Overall survival [ Time Frame: From the time of study enrollment until the time of death, assessed up to 5 years ]
    Will be described graphically and quantitatively using the methods of Kaplan and Meier.

  5. Pathological response rate, defined as extent of tumor in the resected specimen that is classified by tumor, lymph node, metastasis (TNM) staging of the AJCC/International Union Against Cancer (UICC) [ Time Frame: Up to 5 years ]
    Assuming that this measure is binomially distributed, the proportion will be estimated and corresponding 95% binomial confidence intervals generated.

  6. Frequency of patients undergoing sphincter preserving surgery [ Time Frame: Up to 5 years ]
    Assuming that this measure is binomially distributed, the proportion will be estimated and corresponding 95% binomial confidence intervals generated.
