LUGPA 2023: New Standard of Care Introduced in Systematic Therapy

Hi all!

As you settle into the end of the week and are either enjoying the weekend or getting the most you can out of LUGPA’s 2023 Annual Meeting, I wanted to highlight some practice-changing data in bladder cancer that came out of the ESMO 2023 meeting last month in Madrid, Spain.

We arguably saw the introduction of a new standard of care in systemic therapy. However, perhaps even more important for a urology audience, we saw data demonstrating the transition of agents we’ve been using systemically for advanced disease into intravesical formulations to treat non-muscle invasive bladder cancer. This is one of the many reasons it’s essential for urologists in the oncology space to keep up with what’s happening in the medical oncology world.

I’ll close out by highlighting one of the keynote speakers from this year’s LUGPA meeting, Dr. Will Flanary, who brings an interesting and humorous perspective as a patient with a urologic condition.

    • Finally, I want to highlight one of this year’s speakers at the LUGPA meeting, Dr. Will Flanary also known as Dr. Glaucomflecken. While perhaps best known for satirical comedy highlighting the stereotypes of medical specialties – check out his take on the first day of urology – he also brings incredible lived experience to the patient role in health care. Whether you’re at LUGPA or couldn’t make it, take a moment to dive beyond the humor and appreciate all that he brings to the table.

    • While I know we’ve gotten into the weeds with systemic therapy that is typically given by medical oncologists, there were a number of studies presented at ESMO 2023 looking at novel treatment approaches for patients with NMIBC. In the linked discussion, Dr. Jim Catto discusses three abstracts which look at the use of TAR-200 (intravesical slow-release gemcitabine). TAR-210 (intravesical slow-release erdafinitib), and, in THOR-2, a comparison of erdafinitib with intravesical chemotherapy in patients with BCG-refractory NMIBC.

    • I want to also highlight the second cohort of the THOR trial. As presented at this year’s ESMO meeting, cohort 2 compared erdafinitinb and pembrolizumab in patients who had not yet received immunotherapy. In this group, while PFS and response rate were higher with erdafitinib, the primary outcome of overall survival was similar between the two groups. Regardless, this study highlights another potential treatment option for this patient population with a generally poor prognosis.

    • The second study I want to highlight looks at treatment options in patients with metastatic urothelial carcinoma who have already received treatment. This study, THOR, enrolled two cohorts of patients. The first cohort provide a comparison between erdafinitinb and chemotherapy in those who had previously received immunotherapy showed the benefit of erdafinitinb. The primary results of this were presented at ASCO 2023 though the publication was released to coincide with Dr. Loriot’s presentation of subgroup data at ESMO 2023. In patients with FGFR mutations, erdafinitib improved overall survival by more than 4 months. Importantly, Dr. Loriot showed that this effect was seen in essentially all patient groups and across all examined FGFR alterations.

    • In this podcast from the EAU, Dr. Benjamin Pradere and Prof. Thomas Powles discuss the EV-302 trial that Dr. Powles presented at ESMO 2023. EV-302 is a randomized phase 3 trial which evaluated the combination of enfortumab vedotin and pembrolizumab as compared to combination chemotherapy (our current standard of care) as first-line treatment for patients with advanced or metastatic urothelial cancer. The top-line results demonstrated a near doubling of progression free survival (6.3 to 12.5 months and over overall survival (16.1 to 31.5 months). I think this podcast offers an insightful look into the nuances of this trial and these data from the first author himself.
