Non-muscle-invasive bladder cancer (NMIBC) encompasses approximately three-quarters of all bladder cancer (BC) diagnoses. Intravesical Bacillus Calmette-Guerin (BCG) has been the long-standing gold standard treatment for patients following endoscopic resection. However, despite reasonable efficacy, recurrence rates are still suboptimal, and this, combined with treatment tolerability and BCG shortages, has prompted an investigation into alternative treatment modalities. Advances in this landscape have been predominantly for patients with BCG-unresponsive disease, and there are currently four FDA-approved treatments for these patients. More recently, trials have emerged looking for alternatives to BCG for patients who are treatment-naïve. We performed a literature search via PubMed to find recent publications on alternatives to BCG, as well as a search on clinicaltrials.gov and recent conference presentations for ongoing clinical trials. Studies have shown that combination intravesical chemotherapy, combination intravesical therapy with BCG, and combination intravenous therapy with BCG preliminarily have good efficacy and safety profiles in this disease space. Ongoing trials are underway, and we anticipate as these studies mature, there will be a shift in NMIBC treatment regimens.
