Measure Description: The Derkay staging system incorporates an objective score based on the number of sites and bulkiness of papillomas within the pharynx, larynx and trachea, ranging from 0-3 for each site. The total score (combined value of the number of sites and bulkiness of papillomas within the pharynx, larynx and trachea) can range from 0 to 75. Higher values indicate worse disease.
1.Primary Outcome
Title Proportion of Participants With a Complete Response
Hide Description Complete response for M7824 in the treatment of patients with RRP was assessed by the Response Evaluation Criteria in Solid Tumors (RECIST). Complete Response is defined as no evidence of papillomas on physical exam and/or clinic-based flexible nasopharyngolaryngoscopy and/or tracheoscopy or by exam under anesthesia (sedation or general anesthesia) with endoscopy and biopsies, and absence of disease by imaging if lesions are assessed by imaging.
Time Frame Response was assessed by flexible endoscopy with or without imaging studies before treatment and 6 and 12 weeks after starting treatment.

2.Secondary Outcome
Title Number of Participants With a Partial Response
Hide Description Partial response for M7824 in the treatment of patients with RRP was assessed by the Response Evaluation Criteria in Solid Tumors (RECIST). Partial Response is defined as a decrease in Derkay anatomic score of 30 percent or greater, and a partial tumor response by imaging using RECIST 1.1 criteria.
Time Frame Response was assessed by flexible endoscopy with or without imaging studies before treatment and 6 and 12 weeks after starting treatment.

Title Number of Participants With ≥Grade 3 Adverse Events
Hide Description Adverse Events were assessed by the Common Terminology Criteria for Adverse Events (CTCAE v5.0). Grade 3 is defined as severe or medically significant but not immediately life-threatening. Grade 4 is defined as life-threatening consequences; urgent intervention indicated.
Time Frame Per protocol, adverse events are documented from the first administration of the study therapy, Study Day 1, through 42 days after the study therapy was last administered, up to 24 weeks + 42 days.

Title Number of Participants With Serious and Non-serious Adverse Events Assessed by the Common Terminology Criteria for Adverse Events (CTCAE v5.0)
Hide Description Here is the count of participants with serious and non-serious adverse events assessed by the Common Terminology Criteria for Adverse Events (CTCAE v5.0). A non-serious adverse event is any untoward medical occurrence. A serious adverse event is an adverse event or suspected adverse reaction that results in death, a life-threatening adverse drug experience, hospitalization, disruption of the ability to conduct normal life functions, congenital anomaly/birth defect or important medical events that jeopardize the patient or subject and may require medical or surgical intervention to prevent one of the previous outcomes mentioned.
Time Frame Per protocol, adverse events are documented from the first administration of the study therapy, Study Day 1, through 42 days after the study therapy was last administered, up to 24 weeks + 42 days.
