July 10, 2021 updated by: Jing Jin, M.D., Cancer Institute and Hospital, Chinese Academy of Medical Sciences

Phase III Study of Short-term Radiotherapy Plus Neoadjuvant Chemotherapy Versus Preoperative Long-term Chemoradiotherapy in Locally Advanced Rectal Cancer

The purpose of this study is to compare effectiveness of short-term radiotherapy with neoadjuvant chemotherapy(TNT group) with preoperative long-term chemoradiotherapy(CRT group) in locally advanced rectal cancer. The hypothesis is 3-year disease-free survival in TNT group was non-inferior to that in CRT group.

Detailed Description

The study is a prospective phase III randomized multicenter trial. The purpose of this study is to compare short-term radiotherapy with neoadjuvant chemotherapy(TNT group) with preoperative long-term chemoradiotherapy(CRT group) for middle-lower locally advanced rectal cancer. The primary endpoint is 3-year disease-free survival,defined as the interval from randomization to the first occurrence of local-regional failure, distant metastasis, second primary tumor or death from any cause. The primary hypothesis was that DFS in the TNT group would be non-inferior to that in the CRT group. After preoperative radiotherapy and surgery, the DFS rate of LARC fluctuated from 50% to 65%. Assuming a 3-year DFS rate in CRT group is 65%, we consider the 3-year DFS rate in the TNT group is not lower than 54% (e.g., a margin of 11% or equivalently, hazard ratio (HR) < 1.43). Guarding against a 5% ineligibility or drop-out rate, the accrual target was 600 patients, with the final analysis to occur after at least 194 DFS events to provide at least 80% power at 1-sided type 1 error of 0.05. The choices of type 1 error and power were made to provide an appropriate comprise between feasibility, timeliness and statistical rigor of evidence generation.

This study seeks to compare outcomes between two groups with respect to rates of overall survival(OS), distance metastasis free survival (DMFS), and locoregional recurrence free survival (LRRFS).In addition, acute and late toxicity profile, completion of preoperative treatment, the proportion of patients with radical resection (R0), surgical complication profile, the rate of pathological complete response (pCR), and quality of life (QoL) are also secondary endpoints.

The STELLAR-trial has been designed by National Cancer Center/Cancer Hospital, Chinese Academy of Medical Sciences, Peking Union Medical College, and the hypothesis is 3-year disease-free survival in TNT group was non-inferior to that in CRT group.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: TNT group
The intervention of TNT group is Short-course radiotherapy with neoadjuvant chemotherapy, which consists of a short-course radiotherapy (SCRT, 5 Gy x 5 alone), then after 7-10 days of radiotherapy completed, patients will receive neoadjuvant chemotherapy, given in 3 week cycle of capecitabine 1000 mg/m2 twice daily, day 1-14 combined with oxaliplatin 130 mg/m2 once. In total, 4 cycles of neoadjuvant chemotherapy are prescribed preoperatively, then followed by a total mesorectal excision(TME) and postoperative adjuvant chemotherapy. If patients are eligible for postoperative chemotherapy this should consist of at least 2 cycles, which are the same as neoadjuvant chemotherapy.

Other: CRT group
The intervention of CRT group is long-term chemoradiotherapy(CRT), which consists of a long-term chemoradiation (2 Gy x 25 with capecitabine) preoperatively, followed by a total mesorectal excision(TME) and then postoperative adjuvant chemotherapy. The radiotherapy is given in combination with capecitabine in a dose of 825 mg/m2 twice daily on days when radiotherapy, excluding weekends.
