of child-bearing potential and men must agree to use strict and effective
contraception (hormonal or barrier method of birth control; abstinence) during
treatment and for at least 65 days for women and 125 days for men, after the last dose
of M7824 administration. Should a woman become pregnant or suspect she is pregnant
while she or her partner is participating in this study, she should inform her
treating physician immediately.

highly active antiretroviral therapy (HAART), cluster of differentiation 4 (CD4)
counts are greater than 350 cells/mm3 and viral load is undetectable.
- Patients with previously treated brain or central nervous system (CNS) metastases are
eligible provided that the subjects have recovered from any acute effects of
radiotherapy and is not requiring steroids, and any whole brain radiation therapy or
any stereotactic radiosurgery was completed at least 2 weeks prior to M7824
administration.
- Hepatitis B virus (HBV) positive patients are eligible-they must have been treated and
on a stable dose of antivirals (eg, entecavir, tenofovir, or lamivudine; adefovir or
interferon are not allowed) at study entry and with planned monitoring and management
according to appropriate labeling guidance.
- Hepatitis C virus (HCV) positive patients are eligible if participants are on active
HCV therapy at study entry and on a stable dose without documented clinically
significant impaired liver function test or hematologic abnormalities and with planned
monitoring and management according to appropriate labeling guidance.
- Cohort 1A Cisplatin Ineligible Specific Inclusion Criteria (first-line for metastatic
cisplatin-ineligible):
- No prior chemotherapy for inoperable locally advanced or metastatic or recurrent
Urothelial Carcinoma (UC)
---For patients who received prior adjuvant/neoadjuvant chemotherapy or
chemoradiation for UC, a treatment-free interval > 12 months between the last
treatment administration and the date of recurrence is required in order to be
considered treatment naive in the metastatic setting. Prior local intravesical
chemotherapy or immunotherapy is allowed if completed at least 4 weeks prior to
the initiation of study treatment.
- Ineligible ("unfit") for chemotherapy or cisplatin-based chemotherapy as defined
by any one of the following criteria:
- Impaired renal function (CrCl > 30 but < 60 mL/min); GFR should be
calculated per institutional standard.
- A hearing loss (measured by audiometry) of 25 decibels (dB) at two
contiguous frequencies
- Grade greater than or equal to 2 peripheral neuropathy (i.e., sensory
alteration or paresthesias including tingling)
- Eastern Cooperative Oncology Group (ECOG) performance score of 2
- Patient declines chemotherapy after informed discussion with the study
doctor
- Cohort 1B Refractory Post-platinum Therapy Specific Inclusion Criteria (second-line
for metastatic disease):
--Disease progression during or following treatment with a platinum-containing regimen
for inoperable locally advanced or metastatic urothelial carcinoma or disease
recurrence. Examples of regimens include cisplatin + gemcitabine (GC), methotrexate +
vinblastine sulfate + doxorubicin + cisplatin (MVAC), and carboplatin + gemcitabine
(CarboGem).
---Patients who received prior adjuvant/neoadjuvant chemotherapy and progressed within
12 months of treatment with a platinum-containing adjuvant/neoadjuvant regimen will be
considered as second-line patients.
- Cohort 2A Checkpoint Inhibitor Previously Treated Patients that Previously Achieved a
Complete Response (CR) or Partial Response (PR) Specific Inclusion Criteria:
--Patients must have been treated with at least one treatment of a PD-1/PD-L1
checkpoint inhibitor for advance or metastatic UC and achieved a complete response or
partial response by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1
criteria.
- Cohort 2B Checkpoint inhibitor previously treated patients that previously had stable
disease (SD) or progressive disease (PD)
- Specific Inclusion Criteria:
- Patients must have been treated with at least one treatment of a PD-1/PD-L1
checkpoint inhibitor for advance or metastatic UC and had stable disease or a
progressive disease by RECIST 1.1 criteria.
EXCLUSION CRITERIA:
- History of allergic reactions attributed to compounds of similar chemical or biologic
composition to M7824 investigational agents used in the study.
- Uncontrolled intercurrent illness including, but not limited to, symptomatic
congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric
illness/social situations that would limit compliance with study requirements.
- Symptomatic central nervous system metastasis.
- Subjects unwilling to accept blood products as medically indicated
- Pregnant women are excluded from this study because M7824 is an agent with the
potential for teratogenic or abortifacient effects. Because there is an unknown but
potential risk for adverse events in nursing infants secondary to treatment of the
mother with M7824, breastfeeding should be discontinued if the mother is treated with
these agents.
- Patients with any active or recent history of a known or suspected autoimmune disease
(with the exception of diabetes type I, vitiligo, psoriasis, or hypo- or hyperthyroid
diseases not requiring immunosuppressive treatment) or recent history of a syndrome
that required treatment with either systemic corticosteroids (>10 mg daily prednisone
equivalent) or immunosuppressive medications. Inhaled steroids and adrenal replacement
steroid doses up to 10 mg daily prednisone equivalents are permitted in the absence of
active autoimmune disease.
- Patients with a currently active second malignancy other than non-melanoma skin
cancers or cervical carcinoma in situ or incidental organ-confined prostate cancer
found on cystoprostatectomy (provided that the following criteria are met: Stage
T2N0M0 or lower; Gleason score <= 3+4, prostate-specific antigen (PSA) undetectable).
Patients are not considered to have a currently active malignancy if they have
completed therapy and are free of disease for >= 2 years and currently do not require
systemic therapy.
- Patients who have received or will receive a live vaccine within 30 days prior to the
first administration of study intervention. Seasonal flu vaccines that do not contain
a live virus are permitted. Locally approved COVID vaccines are permitted.
