• Must be > 28 days beyond major surgery, including hepatectomy or joint replacement.
• Prior allogeneic bone marrow transplantation or solid organ transplant.
• Spinal cord compression not definitively treated with surgery and/or radiation.
• Any acute illness including fever (> 100.4° F or > 38° C) within 7 days prior to Day 1
• Active systemic bacterial, fungal, or viral infection within 7 days prior to Day 1. Participant cannot have tested positive for COVID-19 within 7 days prior to Day 1.
• Other primary malignancies, except:
  • Adequately treated basal cell or squamous cell carcinoma
  • In situ carcinoma of the cervix or bladder, treated curatively and without evidence of recurrence for at least 2 years prior to the study, or
  • A primary malignancy which has been completely resected and in complete remission for at least 2 years
• Prior grade > 3 immune-related AEs such as pneumonitis, colitis, hepatitis, nephritis; prior dermatitis and endocrinopathies are allowed provided corticosteroids are no longer required and endocrine-replacement therapy is stable and discontinued from prior therapy.
• Active autoimmune disease not related to prior therapy for primary malignancy that has required systemic therapy in the last 1 year.
• Has received:
  • Radiotherapy within 2 weeks of first administration of MT-302
  • Cytotoxic chemotherapy for treatment of the primary malignancy within 28 days or 5 half-lives, whichever is shorter, of administration of MT-302
  • Immune therapy for primary malignancy (eg, monoclonal antibody therapy, checkpoint inhibitors) within 28 days or 5 half-lives, whichever is shorter of first administration of MT-302
  • Targeted therapies for primary malignancy within 28 days or 5 half-lives, whichever is shorter, of first administration of MT-302
  • Anti-cancer vaccine within 12 weeks of first administration of MT-302
  • COVID-19 mRNA vaccine within 6 weeks of first administration of MT-302
• Has received a live vaccine ≤ 6 weeks prior to first administration of MT-302
• Enrollment in another interventional clinical trial within 28 days or 5 half-lives of the drug, whichever is shorter, of first administration of MT-302

Más betegség

• Active infection with human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV).
• History of (noninfectious) pneumonitis/interstitial lung disease that required steroids or has current pneumonitis/interstitial lung disease.
• History of symptomatic congestive heart failure (New York Heart Association classes II-IV) or serious active arrhythmias or other clinically significant cardiac disease within 12 months of enrollment.
• History of an allergic reaction to any of the excipients
• Any other condition that, in the opinion of the Investigator, would make the participant unsuitable for the study or unable to comply with the study requirements.

Laborértékek

• Toxicity from previous anti-cancer therapy defined as toxicities (other than alopecia, or laboratory values listed above) not yet resolved to NCI CTCAE v5.0 Grade ≤ 1 or baseline. Participants with chronic Grade 2 toxicities (eg, peripheral neuropathy, laboratory values) may be eligible per the discretion of the Investigator and Medical Monitor.
• Has received packed red blood cells or platelet transfusion within 2 weeks prior to first administration of MT-302

• Histologically proven, metastatic or advanced epithelial cancer including the following cancer types:
  • Urothelial
  • Cervical
  • Ovarian epithelial
  • Triple-negative breast
  • HR+/HER2- breast
