Personalized vaccine + immunotherapy aims to stop bladder cancer return
NCT ID NCT06534983
First seen Jun 26, 2026 · Last updated Aug 07, 2026 · Updated 7 times
Summary
This phase 2 trial tests whether adding a personalized cancer vaccine (autogene cevumeran) to the immunotherapy drug nivolumab can prevent high-risk bladder cancer from coming back after surgery. About 62 participants will receive either the combination or nivolumab alone. The study has been refocused on safety and treatment continuity.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- autogene cevumeran (personalized cancer vaccine) plus nivolumab (immunotherapy)
- What this could lead to
- If it works, this combination could help prevent high-risk bladder cancer from coming back after surgery.
- What could go wrong
- This is a small, early-phase trial that has been scaled back to focus on safety. The vaccine is personalized, which adds complexity, and it's unclear if the combination is better than nivolumab alone.

Inclusion Criteria: * Participants must have the capacity to participate/enroll in the study and to provide informed consent * Histologically confirmed muscle-invasive UC (also termed transitional cell carcinoma \[TCC\]) of the bladder or upper urinary tract * Tumor-node-metastasis (TNM ) classification (Union for International Cancer Control \[UICC\]/American Joint Committee on Cancer \[AJCC\] 7th edition) at pathological examination of surgical resection specimen of (y)pT3-4 or (y)pN+ and M0 * Surgical resection of MIUC of the bladder or upper tract * Participants who have received neoadjuvant chemotherapy (NAC), including antibody drug-conjugate, either alone or in combination with a checkpoint inhibitor (CPI), are eligible * Participants who have not received any prior NAC are also eligible, provided they meet one of the following criteria, which would make them ineligible to receive adjuvant cisplatin-based therapy: participant refusal, cisplatin ineligibility or investigator decision * Tumor tissue must be provided for biomarker analysis * Absence of residual disease and absence of metastasis, as confirmed by a negative baseline computed tomography (CT) or magnetic resonance imaging (MRI) scan of the pelvis, abdomen, and chest no more than 28 days prior to randomization * Full recovery from cystectomy or nephroureterectomy within 120 days following surgery * Eastern cooperative oncology group (ECOG) performance status of 0 or 1 * Negative human immunodeficiency virus (HIV) test at screening * Negative hepatitis B surface antigen (HbsAg) test at screening * Positive hepatitis B surface antibody (HBsAb), or a negative HBsAb at screening accompanied by either of the following: negative total hepatitis B core antibody (HBcAb) or positive total HBcAb test followed by quantitative hepatitis B virus (HBV) deoxyribonucleic acid (DNA) \< 500 international units/milliliter (IU/mL) * Negative hepatitis C virus (HCV) antibody test at screening, or a positive HCV antibody test followed by a negative HCV ribonucleic acid (RNA) test at screening Exclusion Criteria: * Partial cystectomy in the setting of bladder cancer primary tumor or partial nephroureterectomy in the setting of renal pelvis primary tumor * Any approved anti-cancer therapy, including chemotherapy, or hormonal therapy within 3 weeks prior to initiation of study treatment * Adjuvant chemotherapy, immunotherapy, or radiation therapy for UC following surgical resection * Prior active malignancies within 3 years prior to randomization * Treatment with a live, attenuated vaccine within 4 weeks prior to initiation of study treatment
