Including subcutaneous sasanlimab to Bacillus Calmette-Guérin (BCG) improved recurrence-free survival in non–muscle-invasive bladder most cancers, in accordance with findings from the CREST trial offered on the 2025 ASCO Annual Assembly.
In an interview with CURE, Dr. Petros Grivas defined that the profit was constant throughout subgroups, together with sufferers with T1 illness and carcinoma in situ.
Whereas the therapy’s toxicity was as anticipated for a checkpoint inhibitor, the trial was not designed to evaluate outcomes like metastasis-free or total survival. If accredited, the usage of sasanlimab alongside BCG may elevate sensible questions on care supply and infrastructure wants.
Grivas is the medical director of the Genitourinary Cancers Program and a professor within the Scientific Analysis Division at Fred Hutch Most cancers Middle in Seattle; he additionally serves as a professor within the Division of Hematology and Oncology on the College of Washington Faculty of Drugs.

Query: What have been among the most promising advances in bladder most cancers offered on the assembly, and the way would possibly they alter the way in which you take care of sufferers transferring ahead?
Reply: I am going to begin with non–muscle-invasive bladder most cancers. We noticed knowledge from Dr. Powles on the CREST trial, which evaluated intravesical BCG (Bacillus Calmette-Guérin) induction and upkeep with or with out subcutaneous sasanlimab, a subcutaneously administered checkpoint inhibitor.
The objective of the trial was to find out whether or not including sasanlimab to BCG may enhance outcomes in contrast with BCG alone. The trial was optimistic — the addition of sasanlimab appeared to enhance recurrence-free survival. This can be a promising growth with the potential to vary medical apply, though we’re nonetheless ready to see how regulatory businesses will reply concerning the doable approval of sasanlimab together with BCG.
Dr. Powles additionally offered a subset evaluation on the ASCO annual assembly, which confirmed that the good thing about including sasanlimab was constant throughout totally different affected person subgroups — together with these with T1 illness and people with carcinoma in situ (CIS). The toxicity profile was as anticipated for a systemically administered checkpoint inhibitor.
That stated, there are necessary concerns. The first endpoint of the trial was recurrence of high-grade illness, and most of these occasions have been non–muscle-invasive recurrences. Only some sufferers progressed to muscle-invasive illness, and there have been only a few circumstances of metastasis or loss of life. Because of this, the trial didn’t present ample knowledge to guage metastasis-free survival or total survival.
If sasanlimab does obtain regulatory approval, it can elevate sensible questions on care supply — significantly concerning logistics. For instance, which specialty will likely be chargeable for administering the drug: urology or medical oncology? Do clinics have the required infrastructure, house, employees, and sources — together with nurses and pharmacists — to provide this therapy and monitor sufferers for potential immune-related negative effects?
There’s lots nonetheless to be decided.
