Sasanlimab Treatment As Bladder-Sparing Strategy For Patients With Muscle Invasive Bladder Cancer
EU CTIS ID: 2024-511358-36-00
What this study is testing
To evaluate the bladder-intact overall survival at 12 months after the first dose of sasanlimab. Bladder-intact overall survival is defined as the time from initiation of sasanlimab treatment until death or cystectomy
- Therapeutic exploratory (Phase II)

Who can take part
You may be able to join if
- Patients who sign a written informed consent approved by an IEC for the participation in this trial.

- Male patients with a partner with childbearing potential, or who is pregnant or breastfeeding must agree to abstinence or use a condom plus 1 form of highly effective birth control throughout the study period and for at least 6 months after the final study drug administration.
- Male patients must not donate sperm starting at screening and throughout the study period, and for at least 6 months after the final study drug administration.
- Willing and able to comply with scheduled visits, treatment plan, laboratory tests, and other study procedures.
- Patient agrees not to participate in another interventional study while on treatment in the present study.
You likely can't join if
- Prior treatment with systemic chemotherapy or other approved anticancer treatments for muscle-invasive urothelial cancer of the bladder. Note: In case of prior non muscle-invasive bladder cancer NMIBC, Mitomycin or Bacillus Calmette Guerin (BCG) treatment are allowed.
- Major surgery less than 28 days prior to the first dose of study treatment.
- Clinically significant multiple or severe drug allergies, intolerance to topical corticosteroids, or severe post-treatment hypersensitivity reactions (including, but not limited to, erythema multiforme major, linear immunoglobulin A [IgA] dermatosis, toxic epidermal necrolysis, and exfoliative dermatitis.
- Known or suspected hypersensitivity to active ingredients or excipients of the study drug.
- Pregnant or breastfeeding.
- Any serious or uncontrolled medical disorder, psychiatric or social condition that, in the opinion of the investigator, may increase the risk associated with study participation or study drug administration, impair the ability of the subject to receive protocol therapy, or interfere with the interpretation of study results.

- Histological evidence of localized muscle-invasive urothelial cancer of the bladder (i.e., pT2-T4 / N0 / M0). Histological variants are allowed if the urothelial component is predominantly. Candidate for cystectomy as per treating physician.
- Absence of metastasis as confirmed by CT or MRI scan of pelvis, abdomen and chest no more than 4 weeks pre-enrolment.
- Patients candidates to receive neoadjuvant therapy with gemcitabine and cisplatin. Note:MVAC treatment will not be allowed.
- All subjects must have adequate archival tissue identified at screening (i.e., at least 15 unstained slides or paraffin block). Subjects without archival tissue must be discussed with the Sponsor-investigator.
- Adequate organ and bone marrow function as defined below: a. Absolute neutrophil count (ANC) ≥ 1.5 x 109/L. b. Hemoglobin (HgB) ≥ 9 g/dL. c. Platelet count ≥ 100 x 109/L. d. Creatinine ≤ 1.5 or creatinine clearance ≥ 60 mL/min (Cockcroft-Gault formula). e. Bilirubin ≤ 1.5 × upper limit of normal (ULN). Note: subjects with Gilbert Syndrome, who have total bilirubin < 3.0 mg/dL are eligible. f. Hepatic enzymes Aspartate aminotransferase (AST) and Alanine aminotransferase (ALT) < 3 x ULN.
- Female patients must either: a. Be of nonchildbearing potential: i. Postmenopausal *(defined as at least 1 year without any menses) prior to screening , or ii. Documented surgically sterile (e.g. hysterectomy, bilateral salpingectomy, bilateral oophorectomy, or bilateral tubal occlusion). *Those who are amenorrheic due to an alternative medical cause are not considered postmenopausal and must follow the criteria for childbearing potential subjects. OR b. If of childbearing potential: i. Agree not to try to become pregnant during the study and for at least 6 months after the final study drug administration, ii. And have a negative urine or serum pregnancy test within 7 days prior to Day 1 (females with false positive results and documented verification of negative pregnancy status are eligible for participation), iii. And if heterosexually active, agree to abstinence (if in line with the usual preferred lifestyle of the patient) or consistently use a condom plus 1 form of highly effective birth control (Appendix 7) per locally accepted standards starting at screening and throughout the study period and for a

Note: Participants with either deep vein thrombosis or pulmonary emboli that do not result in hemodynamic instability are allowed to enroll as long as they are stable, asymptomatic and on stable anticoagulants for at least 2 weeks. Note: Participants with thromboembolic events related to indwelling catheters or other procedures may be enrolled.
