Chemoradiation for Rectal Cancer (SMART TNT Trial)

Q: Have regulatory bodies granted their seal of approval to Intensity-modulated radiation therapy?

Assessing Intensity-modulated radiation therapy, our team at Power judged its safety to be a 1 due to the restricted amount of data indicating efficacy and security in this Phase 1 trial.

Q: Is it still possible to register for this particular research study?

This particular clinical trial is currently seeking participants, with the initial posting on October 5th 2022. As of October 28th 2022, no changes have been made to the study's design.

Q: What is the limit of eligible participants in this medical trial?

Affirmative. Documentation on clinicaltrials.gov states that this medical experiment, initiated on October 5th 2022, is actively accepting participants. 25 patients are desired from a single site for the duration of the trial.

SMART TNT Trial Summary

This trial is testing whether it's safe and effective to give chemotherapy to patients with locally advanced rectal cancer before radiation therapy, and whether a higher dose of radiation therapy can help patients avoid surgery.

Who is the study for?

This trial is for adults with newly diagnosed rectal cancer that hasn't spread beyond the pelvis. Participants must have a certain level of physical fitness (ECOG 0-2), acceptable liver function, and no severe heart conditions or immune deficiencies. Pregnant women and those with metal implants incompatible with MRI are excluded.Check my eligibility

What is being tested?

The study tests if starting with chemotherapy followed by higher-than-usual doses of radiation can help patients avoid surgery while effectively treating locally advanced rectal cancer. The chemo drugs used include 5-fluorouracil, Leucovorin, Oxaliplatin, and Capecitabine.See study design

What are the potential side effects?

Potential side effects may include skin changes or irritation from radiation, fatigue, nausea, diarrhea from chemotherapy drugs, increased risk of infections due to lowered white blood cell counts, and possible nerve damage leading to numbness or tingling.

Experimental Treatment

Group I: SMART TNT Plan IIExperimental Treatment1 Intervention

Plan II boost RT (1 week): For participants not achieving cCR after chemo-radiation. Participants will receive MRI-guided accelerated radiation therapy (ART) boost to the primary tumor. Participants achieving a cCR will continue to follow-up. Participants still showing residual tumor will undergo standard of care treatment including surgery and adjuvant chemotherapy per institutional guidelines during follow-up.

Group II: SMART TNT Plan IExperimental Treatment5 Interventions

Participants will initiate therapy with neoadjuvant chemotherapy of either six (6) 14-day cycles of 5-fluorouracil + leucovorin + oxaliplatin (FOLFOX) or four (4) 21-day cycles of capecitabine+oxaliplatin (CAPOX). Participants will then receive chemo-radiation therapy according to Plan I as follows: Plan I (5 weeks): MRI-guided pelvic IMRT to the Planning Tumor Volume (PTV) at a dose of 50 Grays (gy) delivered in 25 fractions (fx) over 5 weeks. Concurrent chemotherapy beginning on Day 1 of RT either: 5-FU delivered 5 or 7 days per week. Capecitabine (Xeloda) delivered 5 days per week. After completing Plan I, participants achieving complete Clinical Response (cCR) after completing Plan I chemo-radiation will forgo the Plan II boost and continue to follow-up. Participants not achieving cCR will begin Plan II, one week after completing Plan I.
