Brief summary

A study of the efficacy and safety of probiotics in immunotherapy of urothelial carcinoma.

Detailed description

To evaluate the progression free survival of intestinal probiotics in immunotherapy for urothelial carcinoma. Changes in fecal flora abundance before and after treatment were assessed to identify subjects most likely to benefit from enteric probiotics treatment.

Interventions

DRUGLive Combined (Bifidobacterium,Lactobacillus and Enterococcus Capsules)

420mg Live Combined (Bifidobacterium,Lactobacillus and Enterococcus Capsules) bid for 4 treatment cycles.

Inclusion criteria

1. Patients diagnosed with urothelial carcinoma and undergoing immunotherapy ; 2. Age ≥ 18 years; 3. Expected survival time is greater than 12 weeks; 4. Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 1 or 2; 5. Organ function level must meet the following requirements: Hematological indexes: neutrophil count \>= 1.5x10\^9/L, platelet count \>= 100x10\^9/L, hemoglobin \>= 9.0 g/dl (can be maintained by symptomatic treatment); Liver function: total bilirubin \<=1.5 ULN, alanine aminotransferase and aspartate aminotransferase \<=2.5 ULN (can be maintained by symptomatic treatment); 6. The subjects volunteered to join the study, signed informed consent, and had good compliance with follow-up; 7. Willing and able to provide written informed consent.

Exclusion criteria

1. Receive live attenuated vaccine within 4 weeks before treatment or during the study period; 2. Active, known or suspected autoimmune diseases; 3. Cannot take orally or are allergic to probiotics ; 4. History of primary immunodeficiency ; 5. Known history of allogeneic organ transplantation and allogeneic hematopoietic stem cell transplantation; 6. Pregnant or lactating female patients; 7. Untreated acute or chronic active hepatitis B or hepatitis C infection. Under the condition of monitoring the virus copy number of patients receiving antiviral treatment, doctors can judge whether they are in line with the patients' individual conditions; 8. Uncontrolled concurrent diseases, including but not limited to: HIV infected (HIV antibody positive); Severe infection in active stage or poorly controlled; Evidence of serious or uncontrollable systemic diseases (such as severe mental, neurological, epilepsy or dementia, unstable or uncompensated respiratory, cardiovascular, liver or kidney diseases, uncontrolled hypertension \[hypertension greater than or equal to conmon terminology criteria for adverse events (CTCAE) grade 2 after drug treatment\]); Patients with active bleeding or new thrombotic disease.

Design outcomes

Primary

MeasureTime frameDescription
Progression-free survival (PFS)up to 3 yearsTime from randomness to the first occurrence of disease progression or death from any cause.

Secondary

MeasureTime frameDescription
Duration of Response (DOR)up to 3 yearsThe time from the first judgment of complete response (CR) or partial response (PR) to the discovery of progressive disease (PD).
Overall Survival (OS)up to 3 yearsDefined as the number of days from study entry to death. Individuals who are alive at last contact will be censored on the date of last contact.
Overall response rate (ORR)up to 3 yearsdefined as the proportion of patients who have a partial or complete response to therapy.
Disease control rate (DCR)up to 3 yearsThe percentage of cases with remission and lesion stability after treatment in the number of evaluable cases.
Serious Adverse Event (SAE)up to 3 yearsThe adverse events that occurred in the study were difficult to manage.

Other

MeasureTime frameDescription
16s rDNA sequencingup to 3 yearsIdentify the subgroups that are most likely to benefit from intestinal probiotic therapy.
