En studie för att ta reda på om Enfortumab Vedotin tillsammans med Pembrolizumab hjälper personer med muskelinvaderande urinblåsecancer att behålla sin urinblåsa
En öppen, enarms, fas 2-studie för att utvärdera enfortumab vedotin plus pembrolizumab för att bevara urinblåsan hos deltagare med muskelinvasiv urinblåsecancer (EV-209)
People with a type of bladder cancer called muscle-invasive bladder cancer have cancer that has spread into the muscle wall of the bladder. The standard treatment is to have chemotherapy, followed by surgery to completely remove the bladder. This has a significant impact on people with long-term life-altering changes. There are also limited options for people who cannot have chemotherapy or who do not want their bladder removed.
Studies show that enfortumab vedotin, when given with pembrolizumab, can help people with advanced bladder cancer. This treatment has also worked well for people with muscle-invasive bladder cancer who can't receive chemotherapy when it was given before and after bladder-removal surgery. However, some people can't have or won't have this surgery. There is still a need for new treatments that let people keep their bladder. This is especially important for people who respond well to the enfortumab vedotin, when given with pembrolizumab, and may benefit from continuing this study treatment instead of having surgery.
The main aims of this study are to check how many people continue to respond well to enfortumab vedotin with pembrolizumab and how many people have their bladder intact after 2 years.
People in this study will be adults who have muscle-invasive bladder cancer and are able to have surgery to remove the bladder.
People cannot take part if they have nerve damage (sensory or motor neuropathy), have had certain other cancers, have diabetes that is not under control, or have had a transplant.
People will receive infusions of enfortumab vedotin on the 1st and 8th day of 3-week (21-day) cycles. They will also receive pembrolizumab on the 1st day of every 3-week cycle. There will be safety checks at each visit with checks of the tumors at some visits. The doctors will continue to check for medical problems throughout the study.
People will continue to receive study treatment unless their cancer doesn't improve after 9 cycles of study treatment, or until their cancer gets worse, they can't tolerate the study treatment, they start other cancer treatment, they or the doctor decides the person should stop receiving study treatment, or sadly they pass away.
People's whose cancer gets worse or doesn't improve after 9 cycles may need bladder surgery, radiotherapy or chemotherapy. People will visit the clinic after they stop their study treatment, in which they will be asked about any medical problems and have a health check. After this, people will continue to have scans every 12 weeks (3 months) for the first 2 years until their cancer gets worse. After this, if their cancer doesn't get worse, they will continue to have scans every 24 weeks (6 months) for up to 5 years to check for any changes in their cancer. After people's cancer gets worse, they won't have any more scans but will have telephone health checks every 3 months.

- Participant with hypothyroidism that is stable with hormone replacement therapy or Sjögren's syndrome will not be excluded.
-
Participant has received prior therapy with an anti-programmed cell death protein 1 (PD-1), anti-programmed death-ligand 1 (PD-L1), or anti-programmed death-ligand 2 agent or with an agent directed to another stimulatory or coinhibitory T-cell receptor (e.g., CTLA-4, OX-40, CD137).
-
Participant has received prior systemic anti-cancer therapy for MIBC/non-muscle invasive bladder cancer (NMIBC), or received prior systemic anti-cancer therapy including investigational agents (including enfortumab vedotin or other monomethyl auristatin E-based antibody-drug conjugates) within 3 years prior to screening.
NOTE: Prior treatment for NMIBC with intravesical instillation therapy such as Bacillus Calmette-Guérin or intravesical chemotherapy is permitted. Prior systemic treatment (including, but not limited to, anti-PD-1/PD-L1 treatment with pembrolizumab, etc.) received for NMIBC is not permitted.
- Participant has received a partial cystectomy of the bladder to remove any NMIBC or MIBC.
- Participant has received any prior radiotherapy to the bladder.

Overall clinical complete response (cCR) rate after treatment with enfortumab vedotin in combination with pembrolizumab as assessed by investigator
Tidsram: Up to 27 weeks
|
cCR rate is defined as the proportion of participants having cCR after treatment with enfortumab vedotin in combination with pembrolizumab. cCR is defined as no visible tumor detected on cystoscopy or no residual tumor on transurethral resection of bladder tumor (TURBT); no evidence of malignancy, except for the presence of Ta (low grade), and no radiographic evidence of residual or metastatic disease on imaging (magnetic resonance urogram [MRU] or computed tomography urogram [CTU] if contraindicated). Bladder wall thickening on imaging is acceptable if not associated with malignancy, except for the presence of Ta (low grade), and negative urine cytology. |
Up to 27 weeks
