100

What were the randomization stratification factors for EV302?

  • Cisplatin eligibility
  • Presence of Liver metastases
  • PD-L1 Expression Status
100

What is THE only 1L NCCN Category 1 Preferred treatment for locally advanced or metastatic urothelial carcinoma?

Enfortumab vedotin + Pembrolizumab

100

This adjuvant MIBC trial was considered negative for its primary endpoint of DFS, but an exploratory analysis related to ctDNA has kept it in the spotlight. Bonus points: Name the sequel

IMvigor010; Atezolizumab; IMvigor011

100

What is the recommended dose reduction schedule for EV?

  • Starting dose: 1.25mg/kg up to 125mg
  • 1st reduction: 1.0mg/kg up to 100mg
  • 2nd reduction: 0.75mg/kg up to 75mg
  • 3rd reduction: 0.5mg/kg up to 50mg
100

Full Approval: 1L la/mUC in combination with pembrolizumab regardless of cisplatin eligibility

EV302

200

What were the ORR and CR rates for EV+P compared to chemotherapy arms?

  • ORR: 67.5% vs. 44.2%
  • CR: 30.4% vs. 14.5%
200

What are other 1L NCCN recommended Category 1 treatment options for la/mUC?

  • Gem/Cis -> Avelumab Maintenance
  • Gem/Cis/Nivo -> Nivo Maintenance
  • DDMVAC -> Avelumab maintenance
200

This MIBC trial made a splash when it showed that using perioperative immunotherapy with neoadjuvant chemotherapy demonstrated significant improvements in pCR, EFS, and OS compared to NAC alone

NIAGARA; Durvalumab

200

In EV302, what was the most common reason for dose holds, changes, and discontinuations? Bonus: What were the rates of those?

  • Peripheral Neuropathy
  • Discontinued: 15%
  • Interrupted: 22%
  • Dose reductions: 13%
200

Accelerated Approval: 2L la/mUC as monotherapy

EV201 C1

300

What were the median PFS and OS for EV+P compared to the chemotherapy arms? (LTFU data)

  • PFS: 12.5 vs. 6.3 months
  • OS: 33.8 vs. 15.9  months
300

Aside from the preferred regimen, what are the other 1L options in patients who are ineligible for cisplatin?

  • Gem/Carbo -> Avelumab maintenance
  • Pembrolizumab (Platinum-ineligible)
  • Atezolizumab (PD-L1(+) and platinum-ineligible)
300

This la/mUC trial showed that OS could go the distance (was improved) by giving immunotherapy to patients whose disease had not progressed after receiving 1L Platinum-based chemotherapy

JAVELIN Bladder 100; Avelumab

300

What is the median TTO of skin reactions with EV+P and how frequently are they seen?

2 months; Seen in 70% of patients in clinical trials

300

Accelerated Approval: 1L la/mUC in combination with pembrolizumab in cisplatin-ineligible patients

EV103K (and 103A/D/E)

400

At ASCO 2025, an exploratory analysis of responders demonstrated that at two years post-randomization, what percent of CR patients had maintained their response? Also, what percent of CR patients were still alive at two years?

  • ~75% maintained CR; ~95% OS rate at 2 years
400

What biomarkers are “often” collected in patients with la/mUC and what potential 2L+ treatment options are their results tied to?

  • FGFR3: Erdafitinib
  • HER2: Trastuzumab deruxtecan (T-DXd) (IHC3+);
400

This la/mUC trial had positive results but ultimately lost the crown at ESMO 2023 when it showed that adding a checkpoint inhibitor to cisplatin-containing chemotherapy improved overall survival. Bonus: name another oft-mentioned facet of this study.

CheckMate901; Nivolumab; Data in LN-only

400

What is the median TTO of Grade 2+ PN with EV+P and how frequently is it seen?

6 months; Seen in 67% of patients in clinical trials

400

Full Approval: 2L la/mUC as monotherapy

EV301

500

The EV302 study protocol had a major amendment during the conduct of the study based on new data presented that changed the treatment landscape. Please explain what the amendment was related to and why it was relevant

Results based on Javelin Bladder 100 and patients being allowed to have avelumab added after completion of chemo

500

Verbalize how NCCN approaches 2L+ therapy for la/mUC

Primarily driven by what was utilized in 1L

500

This trial evaluating an ADC did not meet its primary endpoint of OS and ultimately led to the FDA withdrawing approval in 2L la/mUC after promising Phase 2 results

TROPiCS-04; Sacituzumab Govitecan (still in NCCN guidelines)

500

At what blood glucose level should EV doses be held? Bonus: What was the hyperglycemia-related cutoff for “uncontrolled diabetes” in the EV302 Exclusion Criteria?

>250 mg/dL; HbA1c ≥ 8% (or HbA1c 7%–<8% with associated diabetes symptoms [polyuria or polydipsia] that are not otherwise explained)

500

(Hopefully) Full Approval as perioperative therapy in cisplatin-ineligible MIBC patients
