Bacillus Calmette-Guérin (BCG) in combination with PANVAC™ vs. BCG alone in adults with high-grade BCG-refractory non-muscle-invasive bladder cancer.
Trial report in Urologic oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeWe postulated that PANVAC™, a recombinant poxviral vector vaccine, could enhance the immunologic and clinical response to an additional induction course of bacillus Calmette-Guérin (BCG) in patients with recurrent high-grade non-muscle-invasive bladder cancer (NMIBC).
methodsThis was a randomized, open-label, prospective, phase II study in subjects with high-grade NMIBC who had failed at least 1 induction course of intravesical BCG. Patients were randomized to either BCG alone or BCG+PANVAC. All subjects received intravesical BCG for 6 weeks. Patients in the combination arm also received priming and booster doses of PANVAC. The primary endpoint was recurrence-free survival. Secondary endpoints included progression-free survival and radical cystectomy-free survival. We also evaluated exploratory secondary immunological response endpoints.
resultsOur study concluded based on preplanned futility analysis. Overall, 32 patients were enrolled; 2 withdrew. Thirty patients (15/arm) were analyzed; 5 (33.3%) in the BCG-alone arm and 5 (33.3%) in the BCG+PANVAC arm met criteria for BCG- unresponsive disease. 12-month recurrence-free survival was 53.3% for the BCG-alone arm and 40% for the BCG+PANVAC arm. Overall recurrence rate at any time point was 73.3% at a median of 10.8 months, for an overall recurrence rate of 66.7% in the BCG-alone arm and 80% in the BCG+PANVAC arm. There was no difference in median recurrence-free survival or progression-free survival.
conclusionsThis phase II study demonstrated no improvement in recurrence-free survival with BCG+PANVAC compared to BCG alone in patients with NMIBC who failed to respond to intravesical BCG.
