Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Patients with rectal cancer are assigned to receive preoperative 5 × 5 Gy irradiation over 5 days with total neoadjuvant chemotherapy and camrelizumab, an anti-PD-1 antibody drug. The Primary Objective is to assess clinical complete response of an organ preservation approach and the secondary objective to assess safety in all enrolled patients, local regrowth rate and other cancer specific outcomes (metastasis-free survival, colostomy-free survival and overall survival), longitudinal health-related quality of life of this organ preservation approach.

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.

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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Clinical complete response rate (cCR)
Time Frame: 8 (+/-4 ) weeks
Proportion of patients who achieve a clinical complete response following treatment
8 (+/-4 ) weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Local regrowth rate
Time Frame: 2 year
Presence of adenocarcinoma within the rectal wall or within the mesorectum confirmed by pathology
2 year
Disease free survival (DFS)
Time Frame: 5 year
Five years disease-free survival of this group of patients
5 year
Overall survival (OS)
Time Frame: 5 year
Fives years overall survival of this group of patients
5 year
Incidence of adverse events (AEs)
Time Frame: 1 year
Incidence of adverse events will be assessed according to the latest "Clavien- Dindo Classification of surgical complications" and Common Terminology Criteria of Adverse Events (CTCAE).
