A Safety Study of Enfortumab Vedotin in Indian Adults With Urothelial Cancer

Recruiting now · Phase 4

Conditions studied: Metastatic Urothelial Carcinoma

In brief

This study is for Indian adults in India who have cancer in the bladder lining (urothelial cancer). Their cancer is advanced or has spread to other parts of the body. Enfortumab vedotin is a treatment for this type of cancer. The main aim of the study is to confirm the safety of enfortumab vedotin in Indian adults with urothelial cancer. During the study, people will receive enfortumab vedotin. The study treatment will be given to people slowly through a tube into a vein. This is called an infusion. People will receive 3 separate infusions of enfortumab vedotin in each 28-day (4 weeks) treatment cycle. People visit their study clinic for health-checks several times during and after they receive enfortumab vedotin.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Participant has histologically or cytologically confirmed urothelial carcinoma (i.e., cancer of the bladder, renal pelvis, ureter or urethra). Participants with urothelial carcinoma (transitional cell) with squamous differentiation or mixed cell types are eligible.
• Participant must have experienced radiographic progression or relapse during or after a checkpoint inhibitor (CPI) (anti-PD-1 or anti-PD-L1) for locally advanced (LA) or metastatic disease. Participants who discontinued CPI treatment due to toxicity are eligible provided that they have evidence of disease progression following discontinuation. The CPI need not be the most recent therapy. Participants for whom the most recent therapy has been a non-CPI based regimen are eligible if they have progressed / relapsed during or after their most recent therapy. LA disease must not be amenable to resection with curative intent.
• Participant must have received a platinum-containing regimen (cisplatin or carboplatin) in the metastatic / LA, neoadjuvant or adjuvant setting. If platinum was administered in the ajuvant/neoadjuvant setting, the participant must have progressed within 12 months of completion.
• Participant must have measurable metastatic or LA disease at baseline according to RECIST version 1.1.
• Participant has Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
• Participant's baseline laboratory data meets protocol specified of criteria.
• Female participant is not pregnant and at least 1 of the following conditions apply:
• Not a woman of childbearing potential (WOCBP)
• WOCBP who has a negative urine or serum pregnancy test at screening or within 7 days prior to day 1 and agrees to follow the contraceptive guidance from the time of informed consent through at least 6 months after final study intervention administration.
• Female participant must not be breastfeeding or lactating starting at screening and throughout the investigational period and for approximately 6 months after final study intervention administration.
• Female participant must not donate ova starting at first administration of study intervention and throughout the investigational period and for 6 months after final study intervention administration.
• Male participant must agree to use contraception with female partner(s) of childbearing potential (including breastfeeding partner) throughout the treatment period and for 6 months after final study intervention administration.
• Male participant must agree to remain abstinent or use a condom with pregnant partner(s) for the duration of the pregnancy throughout the investigational period and for 6 months after final study intervention administration.
• Male participant must not donate sperm during the treatment period and for 6 months after final study intervention administration.
• Participant agrees not to participate in another interventional study while receiving study intervention in the present study.

You may not qualify if…

• Participant has preexisting sensory or motor neuropathy grade ≥ 2.
• Participant has active central nervous system (CNS) metastases. Participant with treated CNS metastases is permitted on study if all the following are true:
• CNS metastases have been clinically stable for at least 6 weeks prior to screening
• If requiring steroid treatment for CNS metastases, the participant is on a stable dose ≤ 20 mg/day of prednisone or equivalent for at least 2 weeks
• Baseline scans show no evidence of new or enlarged brain metastasis
• Participant does not have leptomeningeal disease
• Participant has ongoing clinically significant toxicity (grade 2 or higher with the exception of alopecia) associated with prior treatment (including systemic therapy, radiotherapy or surgery).
• Participant with ≤ grade 2 immunotherapy-related hypothyroidism or panhypopituitarism may be enrolled when well-maintained / controlled on a stable dose of hormone replacement therapy (HRT) (if indicated).
• Participant with ongoing ≥ grade 3 immunotherapy-related hypothyroidism or panhypopituitarism are excluded.
• Participant with ongoing immunotherapy-related colitis, uveitis, myocarditis or pneumonitis, or participant with other immunotherapy-related AEs requiring high doses of steroids (> 20 mg/day of prednisone or equivalent) are excluded.
• Participant has history of another malignancy within 3 years before the first dose of study intervention or any evidence of residual disease from a previously diagnosed malignancy.
• Participant with non-melanoma skin cancer, localized prostate cancer treated with curative intent with no evidence of progression, low-risk or very low-risk (per standard guidelines) localized prostate cancer under active surveillance / watchful waiting without intent to treat, or carcinoma in situ of any type (if complete resection was performed) are allowed.
• Participant with a positive hepatitis B surface antigen and/or anti-hepatitis B core antibody and a negative polymerase chain reaction assay at baseline should receive appropriate antiviral prophylaxis or regular surveillance monitoring as per local or institutional guidelines.
• Participant has active hepatitis C infection or known human immunodeficiency virus infection. Participant who has been treated for hepatitis C infection is permitted if they have documented sustained virologic response of ≥ 12 weeks.
• Participant has documented history of a cerebral vascular event (stroke or transient ischemic attack), unstable angina, myocardial infarction, or cardiac symptoms (including congestive heart failure) consistent with New York Heart Association Class III to IV within 6 months prior to the first dose of study intervention administration.
• Participant has known active keratitis or corneal ulcerations. Participant with superficial punctate keratitis is allowed if the disorder is being adequately treated.
• Participant has other underlying medical condition that would impair the ability of the participant to receive or tolerate the planned treatment and follow-up.
• Participant has history of uncontrolled diabetes mellitus within 3 months of the first dose of study intervention. Uncontrolled diabetes is defined as HbA1c ≥ 8 percent or HbA1c between 7 percent and < 8 percent with associated diabetes symptoms (polyuria or polydipsia) that are not otherwise explained.
• Participant has prior treatment with enfortumab vedotin or other monomethyl auristatin E (MMAE)-based antibody drug conjugate (ADCs).
• Participant is currently receiving systemic antimicrobial treatment for viral, bacterial, or fungal infection at the time of first dose of enfortumab vedotin. Routine antimicrobial prophylaxis is permitted.
• Participant has radiotherapy or major surgery within 4 weeks prior to first dose study intervention administration.
• Participant has had chemotherapy, biologics, investigational agents, and/or antitumor treatment with immunotherapy that is not completed 2 weeks prior to first dose of study intervention administration.
• Participant has any condition which makes the participant unsuitable for study participation.
• Participant has a known or suspected hypersensitivity to enfortumab vedotin or to any excipient contained in the drug formulation of enfortumab vedotin (including histidine, trehalose dihydrate, and polysorbate 20); OR participant has known hypersensitivity to biopharmaceuticals produced in CHO cells.
