Description

Summary

This study is a substudy being conducted under one pembrolizumab umbrella master study KEYMAKER-U04. The substudy will consist of 2 parts. Part 1 will evaluate the safety and preliminary efficacy of sacituzumab tirumotecan plus enfortumab vedotin (EV). Part 2 will be based on Part 1 results and will evaluate the efficacy, pharmacokinetics, and safety of sacituzumab tirumotecan plus EV in combination with pembrolizumab in participants with advanced urothelial carcinoma.

Open to people ages 18 years and up

The main inclusion criteria include but are not limited to the following:

  • Must have histologically documented, locally advanced/metastatic urothelial carcinoma (la/mUC).
  • Must provide an archival tumor tissue sample or newly obtained core or excisional biopsy of a tumor lesion demonstrating UC, not previously irradiated, and adequate for biomarker evaluation. A newly obtained biopsy is strongly preferred, but not required if archival tissue is evaluable.
  • Any AEs due to previous anticancer therapies must have recovered to ≤Grade 1 or baseline. Endocrine-related AEs adequately treated with hormone replacement are eligible.
  • PART 1 ONLY: Participants must have received platinum-based chemotherapy for treatment of la/mUC.
  • PART 1 ONLY: Participants must not have received >2 lines of therapy for la/mUC. Platinum-based chemotherapy followed by avelumab maintenance is considered 2 lines of therapy.
  • PART 2 ONLY: Participants must not have received prior systemic therapy for la/mUC.

You CAN'T join if...

The main exclusion criteria include but are not limited to the following:

  • Known additional malignancy that is progressing or has required active treatment within the past 3 years.
  • Known active central nervous system metastases and/or carcinomatous meningitis.
  • Has Grade ≥2 peripheral neuropathy.
  • Has history of documented severe dry eye syndrome, severe Meibomian gland disease and/or blepharitis, or corneal disease that prevents/delays corneal healing.
  • Has active inflammatory bowel disease requiring immunosuppressive medication or previous history of inflammatory bowel disease (eg, Crohn's disease, ulcerative colitis, or chronic diarrhea).
  • Has uncontrolled, significant cardiovascular disease or cerebrovascular disease and/or serious cardiovascular and cerebrovascular diseases within the 6 months preceding study intervention.
  • Has active keratitis or corneal ulcerations. Superficial punctate keratitis is allowed if the disorder is being adequately treated in the opinion of the investigator.

  • Has received an investigational agent or has used an investigational device within 4 weeks prior to study intervention administration.
  • Has received a live or live-attenuated vaccine within 30 days prior to the first dose of study intervention.
  • PART 2 ONLY: Has a diagnosis of immunodeficiency or is receiving chronic systemic steroid therapy or any other form of immunosuppressive therapy within 7 days before the first dose of study intervention. Inhaled or topical steroids are permitted in the absence of active autoimmune disease. Physiologic replacement doses of corticosteroids are permitted for participants with adrenal insufficiency.
  • PART 2 ONLY: Has an active autoimmune disease that has required systemic treatment in past 2 years except replacement therapy. - Is human immunodeficiency virus (HIV)-infected and has a history of Kaposi's sarcoma and/or Multicentric Castleman's Disease.
  • Has active Hepatitis B or Hepatitis C virus infection.
  • Has a history of (noninfectious) pneumonitis/interstitial lung disease that required steroids or has current pneumonitis/interstitial lung disease.
  • Has an active infection requiring systemic therapy.
  • PART 2 ONLY: History of allogeneic tissue/solid organ transplant.
