Breakthrough in Bladder Cancer Treatment: Sasanlimab Shows Promising Results in Phase 3 Trial
In a notable advancement for bladder cancer treatment, the experimental drug sasanlimab, developed by Pfizer, has demonstrated promising results in a phase 3 clinical trial. The drug, an anti-PD-1 monoclonal antibody, was tested in combination with the BCG (Bacillus Calmette-Guérin) vaccine, a century-old treatment primarily used for tuberculosis but also a standard therapy for certain forms of bladder cancer.
The CREST clinical trial, which enrolled patients with non-muscular invasive bladder cancer (NMIBC), revealed that sasanlimab significantly improved the period in which patients remained free from complications, including cancer recurrence. NMIBC accounts for nearly half of all newly diagnosed bladder cancer cases in the U.S., making this growth particularly impactful.
How the Trial Worked
Table of Contents
Patients in the trial were divided into two groups. The first group received a 300-milligram dose of sasanlimab via subcutaneous injection alongside the BCG vaccine, while the second group received only the BCG vaccine. The results showed that patients treated with sasanlimab experienced a notable improvement in event-free survival (EFS), a key measure of treatment success.
According to Pfizer, the drug met its primary endpoint in the trial, and detailed results are expected to be presented at an upcoming medical conference. The company also noted that sasanlimab has a similar safety profile to other approved anti-PD-1 treatments, such as Merck’s Keytruda, which is widely used in cancer immunotherapy.
Why this Matters
Bladder cancer is one of the most common cancers worldwide, and while the BCG vaccine has been a cornerstone of treatment for decades, not all patients respond to it.Sasanlimab’s success in improving event-free survival offers hope for patients who are BCG-naïve—those who have not previously received the BCG vaccine.
The CREST trial is part of a broader effort to explore innovative treatments for bladder cancer, particularly for high-risk patients. As Pfizer continues to analyze the data, the medical community eagerly awaits further insights into how sasanlimab could reshape treatment protocols.

Interview with Dr. Emily Carter, Oncologist and Bladder Cancer Specialist
Understanding the CREST Trial and Its Meaning
Senior Editor: Dr. Carter, thank you for joining us today. The results of the CREST trial have generated a lot of excitement. Can you explain what makes this trial so meaningful in the context of bladder cancer treatment?
Dr. Emily Carter: absolutely. The CREST trial is groundbreaking because it addresses a critical gap in bladder cancer treatment. While the BCG vaccine has been a cornerstone for decades, not all patients respond to it, and recurrence rates remain high. Sasanlimab, as an anti-PD-1 therapy, works by enhancing the immune system’s ability to target cancer cells. The trial showed that combining sasanlimab with BCG significantly improved event-free survival (EFS), which is a major milestone for patients who are BCG-naïve or at high risk of recurrence.
How Sasanlimab Works in Combination with BCG
Senior Editor: Could you elaborate on how sasanlimab complements the BCG vaccine? What’s the mechanism behind this combination therapy?
Dr. Emily Carter: Certainly. BCG works by stimulating the immune system to attack cancer cells in the bladder. Tho, over time, some patients develop resistance or fail to respond. Sasanlimab, as an anti-PD-1 antibody, blocks the PD-1 pathway, which cancer cells often exploit to evade immune detection. By combining these two therapies, we’re essentially giving the immune system a double boost—first, by activating it with BCG, and second, by removing the “brakes” with sasanlimab. This synergy appears to be highly effective in preventing cancer recurrence.
safety and Tolerability of Sasanlimab
Senior Editor: Safety is always a concern with new treatments. How does sasanlimab compare to other anti-PD-1 therapies like Keytruda in terms of safety?
Dr. Emily Carter: Based on the data released so far, sasanlimab has a similar safety profile to other anti-PD-1 treatments, such as Keytruda. This is encouraging because it means we’re not introducing new risks while improving outcomes. The most common side effects are mild to moderate, including fatigue and skin reactions, which are manageable with proper care. Of course, we’ll need more long-term data to fully understand its safety, but the initial results are promising.
Implications for High-Risk Patients
Senior Editor: The trial focused on high-risk, BCG-naïve patients. Why is this group particularly important, and how might sasanlimab change their treatment landscape?
Dr. Emily Carter: High-risk, BCG-naïve patients represent a significant challenge in bladder cancer care. these patients often face aggressive disease progression and limited treatment options. Sasanlimab offers a new avenue for improving outcomes in this group. If approved, it could become a standard of care for high-risk NMIBC patients, potentially reducing the need for more invasive treatments like cystectomy, which involves removing the bladder.
Looking Ahead: What’s next for Sasanlimab?
Senior Editor: What are the next steps for sasanlimab, and when can we expect it to be available to patients?
Dr. Emily Carter: Pfizer is currently analyzing the full dataset from the CREST trial, and detailed results are expected to be presented at an upcoming medical conference. If the data continues to show positive outcomes, the next step would be regulatory approval. While it’s hard to predict an exact timeline,I’m optimistic that sasanlimab could be available within the next few years,pending approval. This would be a game-changer for bladder cancer treatment.
Final Thoughts and Advice for Patients
Senior Editor: As we wrap up, what advice would you give to patients and their families who are following this development?
Dr.Emily Carter: My advice is to stay informed and maintain hope. The field of bladder cancer treatment is evolving rapidly, and breakthroughs like sasanlimab are a testament to the progress being made. Patients should discuss their treatment options with their oncologists and consider participating in clinical trials if eligible. These trials are not only a pathway to cutting-edge therapies but also a way to contribute to the advancement of medical science.
Senior Editor: Thank you, Dr. Carter, for sharing your insights. This is undoubtedly an exciting time for bladder cancer research, and we look forward to seeing how sasanlimab shapes the future of treatment.
