Filter by:This is a single arm, open-label, prospective phase II clinical trial to evaluate the combination of neoadjuvant short-course radiotherapy and immunotherapy (PD-1 antibody) for patients with locally advanced rectal cancer (LARC). A total of 40 patients will be enrolled in this trial to receive 5*5Gy short-course radiotherapy, followed by 4 cycles of CAPOX chemotherapy and PD-1 antibody. Then they will receive the TME surgery and another 4 cycles of CAPOX chemotherapy. There are two cohorts according to the microsatellite instability status: (1) the micro-satellite stable (MSS) cohort（n=32), (2) the MSI-high cohort (n=8). The primary end point is the rate of pathological complete response (pCR). The long-term prognosis and adverse effects will also be evaluated and analyzed.
TORCH is a prospective, multicentre, randomized phase II trial. 130 LARC (T3-4/N+M0, distance from anal verge ≤12cm) patients will be treated with total neoadjuvant therapy (TNT) and assigned to Group A and Group B. Group A receives SCRT (25Gy/5Fx) followed by 6 cycles of Toripalimab combined with CAPOX (ToriCAPOX). Group B receives 2 cycles of ToriCAPOX followed by SCRT and 4 cycles of ToriCAPOX. TME surgery is scheduled after TNT while a watch and wait (W&W) option can be applied to patients achieving clinical complete response (cCR). The primary endpoint is complete response (CR, pathological complete response [pCR] plus cCR) rate. The secondary endpoints include the grade 3-4 acute adverse effects (AE) rate, 3-year DFS rate, etc.
Extramural Vascular Invasion Positive(EMVI+) is a high risk of distant metastasis for locally advanced rectal cancer(LARC) after resection. The study is to evaluate the efficacy and safety of FOLFOXIRI as neoadjuvant chemotherapy alone for EMVI+ LARC in contrast to the efficacy of standard Chemoradiotherapy (CRT).
The study evaluates the addition of immunotherapy of PD-1 antibody in neoadjuvant chemoradiotherapy in microsatellite stable (MSS) locally advanced rectal cancer (LARC). A total of 50 MSS LARC patients will receive 2 cycles of PD-1 antibody, followed by capecitabine plus irinotecan radiosensitized neoadjuvant chemoradiotherapy, and another 3 cycles of PD-1 antibody, finally received the total mesorectal excision (TME) and 6 cycles of adjuvant chemotherapy of XELOX. The tumor response grade, adverse effects and long-term prognosis will be analyzed.
The study evaluates the addition of immunotherapy of PD-1 antibody in neoadjuvant chemoradiotherapy in microsatellite stability-high (MSI-H) locally advanced rectal cancer (LARC). A total of 50 MSI-H LARC patients will receive 2 cycles of PD-1 antibody, followed by capecitabine plus irinotecan radiosensitized neoadjuvant chemoradiotherapy, and another 3 cycles of PD-1 antibody, finally received the total mesorectal excision (TME) and 6 cycles of adjuvant chemotherapy of XELOX. The tumor response grade, adverse effects and long-term prognosis will be analyzed.
The study evaluates the addition of Chinese Herbal Compound Dendrobium Huoshanense Granules to capecitabine and irinotecan in neoadjuvant chemoradiation(CRT) in locally advanced rectal cancer. Half of participants will receive CRT with Dendrobium Huoshanense Granules, while the others will receive CRT with placebo. We will evaluate whether Dendrobium Huoshanense Granules can enhance the immune function and alleviate symptoms caused by the tumor and CRT .
The intention of the study is to explore metabolic and inflammatory parameters in the pelvis and systemically after abdominoperineal resection (APR) for locally advanced rectal cancer (LARC) in patients that have received radiation therapy before surgery. In this study the inflammatory response after laparoscopic robot-assisted APR for LARC will be compared to results obtained in a recent cohort of patients operated with open APR for LARC, which will serve as the control population.
Seamless phase I/II trial with phase I part for determination of maximum tolerated dose (MTD) of Trifluridine/tipiracil, followed by a randomized phase II trial (randomization ratio 2:1) with an experimental arm with Trifluridine/tipiracil based chemoradiotherapy (CRT) and a standard - calibration arm (internal control) with capecitabine CRT flanked by translational research in patients with locally advanced rectal cancer
Extramural Vascular Invasion Positive(EMVI+) is a high risk of distant metastasis for locally advanced rectal cancer(LARC) after resection. The study is to evaluate the efficacy and safety of mFOLFOXIRI as neoadjuvant chemotherapy alone for EMVI+ LARC.
The use of chemoradiotherapy (CRT), in combination with surgery is the standard of care in the treatment of locally advanced rectal cancer. However some patients don't respond well to radiation. More advanced radiotherapy techniques, that result in fewer toxicities, means that we are now able to combine new anti-cancer agents into standard treatment. Targeting the tumour early in this way has the potential to improve response rates. Enadenotucirev is a specific type of anti-cancer virus that only targets cancer cells. It acts in the same way as any virus and can only survive by replicating inside cancer cells and not normal, non-cancerous cells. This means that it can selectively target and destroy tumours, without directly affecting normal cells. It also has the ability to attract cells from the body's immune system to help fight the cancer. The addition of enadenotucirev to standard chemoradiotherapy treatment may have a combined effect on the cancer cells with potentially few, additional side effects. This trial aims to determine the optimal dose and frequency of the virus to give by gradually increasing the number of doses each successive patient receives, and then increasing the dose of the virus itself. Each patient will receive a minimum of 3 doses, up to a maximum of 6, spread over the course of their 5 week standard chemoradiotherapy treatment. Patients will be closely monitored at all times to ensure that with each dosing group, there aren't excessive side effects. Patients will then undergo surgery as part of their standard of care and be followed up for up to 4-6 weeks post-surgery. This trial aims to determine the optimal dose and frequency that can then be used in future studies with the possibility of exploring the addition of Enadenotucirev to other chemoradiotherapy treatments.
