A multi-center Phase 2 study of neoadjuvant immunotherapy in combination with the anti-GDF-15 antibody visugromab (CTL-002) for the treatment of muscle invasive bladder cancer
EU CTIS ID: 2024-513957-55-00
What this study is testing
To assess the anti-tumor activity of visugromab (CTL-002) administered in combination with an anti-programmed death receptor-1 (PD-1) checkpoint inhibitor, compared to an anti-PD-1 checkpoint inhibitor alone in the neoadjuvant setting in participants with muscle-invasive bladder cancer (MIBC).
- Therapeutic exploratory (Phase II)

Who can take part
You may be able to join if
- Able to understand the purpose of the trial, provide signed and dated informed consent prior to performing any protocol-related procedures (including Screening evaluations), and comply with the trial procedures.
- If participant has Type II diabetes and receives metformin, metformin has to be replaced with other antidiabetic(s) prior to start of trial treatment (at minimum 7 days prior to trial baseline GDF-15 measurement) and for the whole trial treatment duration.
- Women of childbearing potential must have a negative serum pregnancy test within 7 days prior to trial treatment. Women of childbearing potential are defined as sexually mature women without prior hysterectomy or who have had any evidence of menses in the past 12 months. However, women who have been amenorrheic for 12 or more months are still considered to be of childbearing potential if the amenorrhea is possibly due to prior chemotherapy, anti-estrogens, or ovarian suppression.
- All participants, male and female, who are not surgically sterilized or postmenopausal as defined below, and participants’ partners of childbearing potential must agree to use “highly effective methods of contraception” during the trial and for at least 5 months (5 times the predicted halflife of visugromab [CTL-002] in humans) after the last dose of IMP. “Highly effective methods of contraception” are combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation, progestogenonly hormonal contraception associated with inhibition of ovulation, intrauterine device, intrauterine hormone-releasing system, bilateral tubal occlusion, vasectomized partner, or sexual abstinence. The double-barrier method (synthetic condoms, diaphragm, or cervical cap with spermicidal foam, cream, or gel), periodic abstinence (such as calendar, symptothermal, or postovulation), withdrawal (coitus interruptus), lactational amenorrhea method and spermicide only are NOT acceptable as “highly effective methods of contraception.” Postmenopausal is defined as at least 12 months after last menstrual bleeding without an alternative medical cause (e.g., amenorrhea due to prior chemotherapy, anti-estrogens, or ovarian suppression)
- Age ≥ 18 years
- Histopathologically confirmed urothelial carcinoma. Participants with mixed histologies are required to have a dominant (i.e., 50% at least) transitional cell pattern.
You likely can't join if
- Pregnant or breastfeeding.
- QT interval corrected for heart rate using Fridericia’s formula interval ≥ 470 ms regardless of sex.
- Any active autoimmune disease that requires systemic immunosuppressive treatments, for which (re-)activation may present a medical threat to the participant as per the Investigator’s assessment.
- Any history of non-infectious pneumonitis < 6 months prior to Screening.
- Any active inflammatory bowel disease such as Crohn’s disease or ulcerative colitis or active autoimmune thyroiditis, all present < 6 months prior to Screening.
- History of CNS disease such as stroke, seizure, encephalitis, or multiple sclerosis (< 6 months prior to Screening).
