About this study
Official title: An Open Intervention Study of Nocardia Rubra Cell Wall Skeleton in Combination With Prior Second- or Third-line Regimens for the Treatment of Potentially Hazardous Colorectal Cancer SD(Stable Disease) Status
Evaluate the efficacy and safety of Nocardia rubra cell wall skeleton in combination with prior second- or third-line regimens for the treatment of potentially hazardous colorectal cancer SD(Stable Disease) status in the real world.
Read the detailed description
This is a prospective interventional clinical trial investigating the efficacy and safety of Nocardia rubra cell wall skeleton in combination with prior second- or third-line regimens for the treatment of potentially hazardous colorectal cancer SD (Stable Disease) status in the real world.
Enrollment requirements were patients who had received prior second- or third-line therapy for advanced or metastatic colorectal cancer and presented with a potentially harmful SD status.
The potentially hazardous SD (Stable Disease) state is defined as an increase in SLD (Sum of Longest Diameters) by less than 20% according to RECIST 1.1 criteria, with an absolute increase of SLD ≤ 5mm from the nadir; a serum CEA (Carcinoembryonic Antigen) level below 10.0 ng/ml during stable disease, with two consecutive measurements of 10 ng/ml or more (with a testing interval of at least one month); or a serum CEA level of 10 ng/ml or more during stable disease, with a gradual increase in CEA after two consecutive measurements (with a testing interval of at least one month); a serum CA19-9 level below 60.0 ng/ml during stable disease, with two consecutive measurements of 60 ng/ml or more (with a testing interval of at least one month); or a serum CEA level of 60 ng/ml or more during stable disease, with a gradual increase in CEA after two consecutive measurements (with a testing interval of at least one month). Meeting any one of the above criteria can be considered as the presence of a potentially hazardous SD state.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Nocardia Rubra Cell Wall Skeleton in Combination With Prior Second- or Third-line RegimensDrug
Nocardia Rubra Cell Wall Skeleton 200 mcg-400 mcg, 0.3 ml diluted in water for injection or lidocaine, was injected subcutaneously every 2 or 3 weeks.
Efficacy was evaluated every 2 cycles according to RECIST 1.1 criteria. Patients are enrolled and given this study regimen of drugs on top of their prior second- or third-line regimen until disease progression or intolerable toxicities occur; or the patient requests to be discharged.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Nocardia Rubra Cell Wall Skeleton in Combination With Prior Second- or Third-line Regimens in people with Colorectal Cancer and Colorectal Neoplasms, run by Sun Jing at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 8 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 8 Aug 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Jing Sun (13914704178, sunj@njmu.edu.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Progression-free survival(PFS) (time frame: 1 year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Aug 2025; AzTrials last refreshed its copy on 31 Oct 2026.
