Bavencio as first-line upkeep was related to long-term efficacy in superior urothelial carcinoma no matter sufferers’ diabetes standing.
Remedy with Bavencio (avelumab) as first-line upkeep was related to long-term efficacy and constant security in sufferers with superior urothelial carcinoma no matter if they’d diabetes mellitus or not, in accordance with analysis shared on the 2025 ASCO Genitourinary Cancers Symposium, Dr. Petros Grivas emphasised.
The JAVELIN Bladder 100 trial beforehand examined whether or not including Bavencio to finest supportive care improved survival in sufferers inside this inhabitants, main investigators to launch an discover exploratory evaluation to look at if having diabetes affected remedy outcomes. Whereas these findings counsel Bavencio is efficient and protected for sufferers with or with out diabetes mellitus, additional analysis is required to verify these outcomes, investigators concluded.
In an interview with CURE, Grivas sat down to debate the subject of the sub-study and expanded on how these findings might affect remedy selections for oncologists managing superior urothelial carcinoma. Grivas at present serves because the medical director of the Genitourinary Cancers Program and a professor within the Scientific Analysis Division at Fred Hutch Most cancers Heart, in Seattle, in addition to a professor within the Division of Hematology and Oncology, on the College of Washington College of Drugs.

CURE: How does the presence of diabetes mellitus impression the effectiveness of immunotherapy in sufferers with superior urothelial carcinoma?
Grivas: [Data] from the JAVELIN Bladder 100 section 3 trial [showed] that swap upkeep with Bavencio — an anti-PD-1 immunotherapy —[demonstrated] important general and progression-free survival with Bavencio swap upkeep. Now we have carried out many research since then, and the panorama continues to vary. Clearly, we have now practice-changing information [since then], so the panorama has modified considerably in the previous few years.
A sub-study, [also called an] exploratory evaluation, was carried out particularly sufferers with and with out diabetes mellitus. The important thing takeaway was that the profit with Bavencio swap upkeep within the context of the JAVELIN Bladder 100 trial was impartial of the presence of diabetes. Each sufferers with and with out diabetes mellitus benefited from Bavencio swap upkeep remedy after responding to or attaining secure illness with platinum-based chemotherapy.
Provided that diabetes is a typical comorbidity, what precautions or modifications must be thought of when treating sufferers with superior urothelial carcinoma who’ve diabetes?
Now we have to take [medical comorbidities], like diabetes mellitus, under consideration after we deal with sufferers. I all the time suggest very shut follow-up with main care suppliers and endocrinologists to optimize the remedy of diabetes mellitus. Diabetes, by itself, represents a big threat for sufferers for heart problems and cardiovascular issues. I feel this turns into much more related now that we use a number of Padcev (enfortumab vedotin-ejfv) plus Keytruda (pembrolizumab).
The section 3 EV-302/KEYNOTE-A39 trial demonstrated a big general and progression-free survival profit with Padcev plus Keytruda versus platinum-based chemotherapy, making it the popular commonplace of care. Padcev may cause hyperglycemia in about 10% of sufferers, in order that makes it related to this dialogue. We wish sufferers with diabetes, each managed and uncontrolled, to be adopted intently by main care suppliers and endocrinologists to optimize blood sugar management.
Now we have to pay very shut consideration to these sufferers no matter remedy, and naturally, whereas treating them with Padcev, to maintain observe of their blood sugar. We need to provide one of the best remedy to our sufferers with diabetes mellitus, and we have to pay additional consideration to blood sugar and keep very shut follow-up. We must always have a multidisciplinary strategy in collaboration with main care suppliers and endocrinologists for optimum management of diabetes mellitus, no matter therapies.
As you stated, the JAVELIN Bladder 100 trial confirmed extended general and progression-free survival with Bavencioregardless of diabetes standing. How ought to these findings affect remedy selections for oncologists managing superior urothelial carcinoma?
Now we have three practice-changing section 3 trials: the JAVELIN Bladder 100 trial with swap upkeep Bavencio in sufferers with no development after prior platinum-based chemotherapy; the CheckMate 901 trial, the place gemcitabine plus cisplatin plus Opdivo (nivolumab) was higher than gemcitabine plus cisplatin in cisplatin-eligible sufferers; and the EV-302 trial, with Keytruda plus Padcev, exhibiting dramatic enchancment in progression-free and general survival in contrast with platinum-based chemotherapy.
I feel, general, Keytruda plus Padcev, primarily based on the EV-302 trial, is the popular commonplace of care. Nevertheless, in lots of nations, this routine or mixture just isn’t out there as a consequence of lack of entry or reimbursement. I feel that is vital to notice as a result of there are disparities in healthcare throughout completely different nations. Particularly in nations the place this Keytruda mixture just isn’t out there, we have now to think about much more the information from the JAVELIN Bladder 100 trial with swap upkeep Bavencio, significantly for sufferers who’re cisplatin-ineligible and can’t obtain cisplatin; the gemcitabine plus cisplatin plus Opdivo information don’t apply to them.
The JAVELIN Bladder 100 trial stays the usual of care in nations the place Keytruda plus Padcev just isn’t out there for cisplatin-ineligible sufferers. I feel it is vital to maintain these three practice-changing trials in thoughts. Now we have to make one of the best individualized, personalised choice in medical observe. We talk about the information with our sufferers. We bear in mind medical comorbidities, efficiency standing, and organ perform. We need to guarantee we think about these related medical components after we make knowledgeable and shared selections with our sufferers.
It is also vital to listen to our sufferers’ priorities, needs and remedy expectations, to think about efficacy information, toxicity information, high quality of life and patient-reported outcomes information. To make knowledgeable selections with our sufferers, we need to use one of the best remedy we have now upfront. On the identical time, we have now to think about the actual particulars and particular context for particular person sufferers.
What additional analysis is required to higher perceive the interaction between diabetes, immune response and remedy outcomes?
Diabetes is a typical medical comorbidity in these sufferers and it, by itself, represents a threat for cardiovascular occasions. By way of remedy, the extremely related level is that Padcev may cause hyperglycemia in about 10% of sufferers, or one out of ten, and about half of these instances, round 5%, might doubtlessly be extreme and, in uncommon instances, life-threatening. So, we have now to concentrate to the glucose ranges of these sufferers, monitor their metabolic panels. [We must] work along with main care suppliers and endocrinologists to optimize the management of diabetes, which will be useful throughout the board.
I feel it is vital to maintain exploring information from completely different medical trials and replace the information units with longer follow-up, and to have a look at completely different subsets of sufferers. A few of these subsets could also be underpowered to present definitive solutions, however they’ll at the very least generate hypotheses. It is positively vital to have a look at all these trials and attempt to preserve updating the information, preserve delving into related questions, and elevating hypotheses that may be examined in subsequent trials.
General, the secret’s to synthesize these information units and have a really knowledgeable, detailed dialogue with our sufferers to assist them make an knowledgeable choice.
