Success Rate of Immunotherapy for Bladder Cancer. What Patients Need to Know in 2025
The success rate of immunotherapy for bladder cancer has become a central question for patients and oncologists alike. Bladder cancer is one of the most common malignancies of the urinary tract, accounting for over 600,000 new cases and 220,000 deaths worldwide each year (Sung et al., 2021). It has long been considered an immune-responsive tumor, making it a leading model for understanding how the immune system can control or eliminate cancer.
For decades, intravesical Bacillus Calmette–Guérin (BCG) has been the standard of care for early-stage disease, representing one of the earliest successful uses of immunotherapy in oncology. More recently, immune checkpoint inhibitors have revolutionized treatment for advanced or metastatic bladder cancer, providing durable responses and prolonged survival for a subset of patients. However, the success rate of immunotherapy for bladder cancer varies widely depending on the disease stage, molecular profile, and therapeutic strategy used.

Immunotherapy in Bladder Cancer: A Brief Overview
Immunotherapy works by mobilizing the patient’s immune system to identify and destroy malignant cells. In bladder cancer, the immune system’s interaction with tumor tissue is especially significant due to the tumor’s high mutational load and immune infiltration. This biological context helps explain why the success rate of immunotherapy for bladder cancer is higher than for many other solid tumors.
The two major forms of immunotherapy currently used in bladder cancer are intravesical BCG for non–muscle-invasive tumors and systemic immune checkpoint inhibitors for locally advanced or metastatic disease. Both approaches aim to enhance the immune response against cancer, but their mechanisms and success rates differ.
Non–Muscle-Invasive Bladder Cancer and BCG Immunotherapy
In non–muscle-invasive bladder cancer (NMIBC), BCG remains the cornerstone of treatment. Administered directly into the bladder, it stimulates a local immune response that targets tumor cells. Numerous studies have demonstrated that BCG therapy prevents recurrence in 60–70% of patients and delays disease progression in about 30–40% (Sylvester et al., 2002). These results underscore the high success rate of immunotherapy for bladder cancer at this early stage.
However, not all patients respond favorably. Around one-third of individuals are considered “BCG-unresponsive,” meaning the disease recurs or persists despite adequate treatment. For these patients, alternative approaches are essential. Recently, systemic immunotherapy with checkpoint inhibitors has emerged as a valuable option for BCG-unresponsive NMIBC, further extending the reach of immunotherapy beyond local treatment.
Immunotherapy for BCG-Unresponsive Disease
For patients whose tumors do not respond to BCG, pembrolizumab has provided new hope. The KEYNOTE-057 trial demonstrated that pembrolizumab achieved a complete response rate of 41% at three months among patients with carcinoma in situ, and nearly 20% maintained that response for at least one year (Balar et al., 2021). These results represent a meaningful advance in the success rate of immunotherapy for bladder cancer at the non-muscle-invasive stage.
While not every patient experiences durable benefit, pembrolizumab offers a bladder-sparing alternative to surgery for those who are ineligible for or decline cystectomy. The trial’s long-term follow-up continues to show that a subset of patients achieve sustained remission, highlighting the potential of systemic immunotherapy to change the natural course of early-stage bladder cancer.
Advanced and Metastatic Disease: Expanding the Benefits
In advanced or metastatic urothelial carcinoma, immune checkpoint inhibitors have redefined the treatment paradigm. The pivotal KEYNOTE-045 study compared pembrolizumab to chemotherapy in patients whose disease had progressed after platinum-based treatment. The overall response rate was 21% for pembrolizumab compared with 11% for chemotherapy, and median overall survival increased from 7.4 months to 10.3 months (Bellmunt et al., 2017). The durability of these responses significantly improved the success rate of immunotherapy for bladder cancer in this challenging setting.
Atezolizumab produced similar outcomes in the IMvigor210 study, with response rates ranging between 15% and 23%, particularly in patients whose tumors expressed high levels of PD-L1 (Rosenberg et al., 2016). Importantly, many of these responses lasted years, with some patients maintaining complete remission long after treatment discontinuation.
Perhaps the most transformative progress has come from avelumab maintenance therapy. The JAVELIN Bladder 100 trial demonstrated that patients who received avelumab maintenance after first-line chemotherapy had a median overall survival of 21.4 months, compared to 14.3 months with best supportive care (Powles et al., 2020). This established maintenance immunotherapy as a new global standard and pushed the success rate of immunotherapy for bladder cancer to unprecedented levels in metastatic disease.

Determinants of Success
The variability in the success rate of immunotherapy for bladder cancer can be explained by differences in tumor biology, immune microenvironment, and patient factors. Tumors with high PD-L1 expression or elevated tumor mutational burden tend to respond better to checkpoint inhibitors. Similarly, mutations in DNA damage repair (DDR) genes are associated with increased immune sensitivity. Conversely, patients with immune-cold tumors, few infiltrating lymphocytes, or liver metastases often experience limited benefit.
Beyond biological features, clinical factors such as performance status, comorbidities, and prior therapies also affect outcomes. Researchers are working to refine predictive biomarkers to identify which patients are most likely to achieve durable responses, thereby improving the overall success rate of immunotherapy for bladder cancer through precision medicine.
Combination Approaches: Toward Higher Success Rates
To enhance efficacy, ongoing trials are combining immunotherapy with chemotherapy, targeted therapy, or antibody–drug conjugates. One of the most promising examples is the combination of pembrolizumab with enfortumab vedotin, evaluated in the EV-103/KEYNOTE-869 trial. This regimen produced an extraordinary response rate of 73% and a complete response rate of 15% in previously untreated metastatic bladder cancer (Yu et al., 2021). Such findings suggest that the future success rate of immunotherapy for bladder cancer could exceed current benchmarks as combination strategies become standard practice.
Limitations and Challenges
Despite these advances, several challenges remain. Not all patients benefit from immunotherapy, and resistance—either primary or acquired—remains common. Adverse events such as pneumonitis, colitis, or thyroid dysfunction can occur, sometimes necessitating treatment interruption. Access to genomic testing and immunotherapy agents may also be limited in certain regions, creating disparities in care that influence real-world outcomes.
Nevertheless, ongoing research and the development of next-generation immunotherapies promise to overcome many of these obstacles. By integrating molecular diagnostics, artificial intelligence, and adaptive trial designs, clinicians aim to further increase the success rate of immunotherapy for bladder cancer globally.
The Future of Immunotherapy in Bladder Cancer
Looking ahead, immunotherapy is expected to remain at the forefront of bladder cancer treatment. The focus is shifting toward biomarker-guided therapy, novel immune targets such as TIGIT and LAG-3, and personalized combination regimens. Clinical trials are increasingly using artificial intelligence to analyze genomic and imaging data, helping to predict which patients will respond best.
As scientific understanding deepens, it is anticipated that the success rate of immunotherapy for bladder cancer will continue to climb, potentially transforming the disease from a terminal condition into a chronic, manageable one for many patients.
Conclusion
The success rate of immunotherapy for bladder cancer depends on disease stage, treatment type, and tumor biology. For non–muscle-invasive disease treated with BCG, recurrence prevention rates reach up to 70%. For BCG-unresponsive disease treated with pembrolizumab, complete responses occur in about 40% of patients, with some maintaining remission beyond one year. In advanced or metastatic bladder cancer, checkpoint inhibitors achieve response rates of approximately 20–25%, while maintenance avelumab extends median survival beyond 21 months. Combination therapies such as pembrolizumab with enfortumab vedotin are now pushing response rates past 70%, marking a new era in bladder cancer care.
While immunotherapy is not universally effective, its ability to deliver durable, long-term control represents one of the greatest achievements in modern oncology. Continued innovation, precision biomarker use, and global accessibility will further improve the success rate of immunotherapy for bladder cancer, bringing hope to thousands of patients each year.

Meet the 7p penny stock that two brokers think could soar 113%
Image source: Getty Images Finding the right penny stock can turbocharge returns. Just look at Defence Holdings, a small-cap that’s developing AI-enabled software defence systems. It’s up 4,380% in one year!
In reality though, successful penny stocks are rare beasts, and this type of eye-popping return is rarer still. But for investors with a high risk tolerance, it may be worth digging into businesses operating in growth markets with untapped future potential.
Agronomics (LSE:ANIC) certainly falls into this category. It’s a venture capital company focused on the nascent fields of cellular agriculture and precision fermentation.
This area is often called ‘clean food’ or ‘cultivated meat’, as it involves growing animal products directly from cells instead of raising whole animals.
So far, Agronomics has invested in more than 20 start-ups. These include SuperMeat (cultivated chicken), BlueNalu (cultivated seafood), Meatable (cultivated pork and beef), and VitroLabs (cultivated leather).
Of course, these names will be obscure to most investors, as they’re still largely early-stage. However, some are starting to commercialise their products and services.
Last month, for example, portfolio holding Clean Food Group received regulatory approval for its CLEAN Oil 25 to be used as a cosmetic ingredient in the UK, US, and Europe. Clean Foods manufactures sustainable oils and fats through fermentation.
Developed in collaboration with THG LABS and Croda International, this breakthrough product is a sustainable alternative to conventional oil ingredients in the skincare, haircare, and wider personal care categories (all massive markets).
Palm oil is used in around 70% of cosmetic products, and it remains one of the leading drivers of tropical deforestation. For decades, the beauty industry has faced a difficult challenge, aware of the damage caused by palm oil, but unable to replace it due to its unique properties. Today, that changes with this new regulatory approval.
Significant commercial progress like this should start to drive portfolio returns. To date, Agronomics has invested a total of £1.6m into Clean Food Group. Subject to audit, the firm says this is currently carried at £6.9m, representing a significant uplift.
The position represents around 4.8% of Agronomics’ last stated net asset value (NAV), as calculated in June. That was 14.4p per share, which suggests the shares at just under 7p are trading at more than a 50% discount to NAV.
It goes without saying that this stock is very much in the high-risk, high-reward camp. There’s no guarantee these start-ups will ever find commercial success, while a consumer backlash against lab-grown food could torpedo investor sentiment (and funding) for the sector.
