💬In plain words
What the trial is, and whether it could suit you
STAR-EV will evaluate the combination of enfortumab vedotin plus radiotherapy (RT) as neoadjuvant treatment for bladder cancer prior to radical cystectomy surgery. The study will use "dose escalation" to evaluate the safety and efficacy of study treatment at three dose regimens:
Level 0: EV treatment followed by RT to the bladder Level 1: EV treatment with RT starting on Cycle 2, Day 15 Level 2: EV treatment with RT starting on Cycle 1, Day 15
Following completion of EV+RT neoadjuvant therapy, all subjects will undergo surgery as part of routine care.

📋 Eligibility rules (as published)
Inclusion Criteria:
1. Urothelial carcinoma of the urinary bladder stage cT1-4a (AJCC 8th edition) N0M0 planned for radical cystectomy.
2. For cR1 staged patients. the patient must have high grade disease AND be appropriate for cystectomy.
3. Mixed cell types with variant histologies (including squamous, plasmacytoid, adenocarcinoma, sarcomatoid, micropapillary, nested, and lipid cell variants) are allowed as long as any urothelial histology is present (i.e. -not 100% variant histology). Small cell/neuroendocrine component is excluded.
4. Age \>=18.
5. Performance status Eastern Cooperative Oncology Group (ECOG) 0-1
6. Adequate organ and marrow function as defined below:
•Hematologic:
-Absolute neutrophil count (ANC) \>=1500/mm3
* Platelet count \>=100x109/L
* Hemoglobin ≥ 9 g/dL
•Hepatic:
* Serum bilirubin ≤ 1.5 × upper limit of normal (ULN) or ≤ 3 × ULN for subjects with Gilbert's disease
* Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 2.5 × ULN
•Renal:
* No end stage renal disease requiring dialysis allowed
7. All men, as well as women of child-bearing potential must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation, and for 3 months following completion of study neoadjuvant therapy. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately.
7a. A female of child-bearing potential is any woman (regardless of sexual orientation, marital status, having undergone a tubal ligation, or remaining celibate by choice) who meets the following criteria:
* Has not undergone a hysterectomy or bilateral oophorectomy; or
* Has not been naturally postmenopausal for at least 12 consecutive months (i.e., has had menses at any time in the preceding 12 consecutive months).
8\. Ability to understand and the willingness to sign a written informed consent.
Exclusion Criteria:
1. No prior systemic therapy (except prior therapy for non-muscle invasive bladder cancer \>12 prior to registration) for bladder cancer or prior pelvic radiotherapy. Prior intra-vesical therapies are allowed, including Bacillus Calmette-Guerin (BCG) for non-muscle invasive bladder cancer. Prior chemotherapy for other cancers is allowed if given \>=1 year prior to study registration.
2. Baseline \>= Grade 2 sensory or motor neuropathy
3. Subjects may not be receiving any other investigational agents for the treatment of the cancer under study.
4. History of allergic reactions attributed to compounds of similar chemical or biologic composition to enfortumab vedotin or other agents used in study.
5. Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that, in the opinion of the investigator, would limit compliance with study requirements.
6. Subjects must not be pregnant or nursing due to the potential for congenital abnormalities and the potential of this regimen to harm nursing infants.
