Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

List	Outcome	Time frame	Description
Primary	Phase I: Recommended Phase II Dose of PRGN-2009	Date treatment consent signed to date off study, approximately 18 months	Phase I: To determine the recommended phase II dose (RP2D) of PRGN-2009 Human Papillomavirus Vaccine (HPV) vaccine alone or in combination with M7824 (MSB0011359C). Recommended Phase 2 Dose, the dose of a drug or drug combination that was identified in a Phase 1 study (dose finding study) that was identified for continued study.
Primary	Phase I: Safety - Number of Treatment-related Serious Adverse Events (AE) of Grades 1, 2, 3, 4 and/or 5 Along With the AE Term	Date treatment consent signed to date off study, an average of 6 months	Adverse events were assessed by the Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. 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. Grade 1 is mild. Grade 2 is moderate. Grade 3 is severe. Grade 4 is life-threatening. Grade 5 is death related to adverse event. All participants who receive any investigational treatment will be evaluable for safety and toxicity evaluations.
Primary	Phase II: Percentage of Participants That Had a 2-fold Increase of Cluster of Differentiation 3 (CD3+) Tumor Infiltrating T Cells in Biopsies Performed Post-treatment Compared to Pre-treatment	Pre-Treatment (Baseline) and anytime between Week 4-5 post treatment	CD3+ tumor infiltrating T cells post treatment compared with pre-treatment reported with a 95% confidence interval assessed by multiplex CD3+ tumor infiltrating lymphocytes assessed by multiplex immunofluorescence from the surgical/ biopsy tissue collected pre- and post-treatment. The percentage of participants with doubling of baseline CD3+ tumor infiltrating lymphocytes will be provided as well as the 95% confidence interval. The CD3 cells are assessed by multiplex immunofluorescence in the biopsies. Doubling is the desired outcome.
Secondary	Phase I: Proportion of Participants That Are Hospitalized Because of Adverse Events Attributed to Disease Progression	Date treatment consent signed to date of progression, an average of 6 months	Phase I: proportion of participants that are hospitalized because of adverse events attributed to disease progression. Adverse events were 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. Disease progression was assessed by the Response Evaluation Criteria in Solid Tumors(RECIST) and is defined as at least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study. The appearance of one or more new lesions is also considered progression.
Secondary	Phase II: 3-year Overall Survival for PRGN-2009 Alone	3 years	Phase II: Overall survival assessed using the Kaplan-Meier method, defined as the time from the date of first treatment to the date of death (any cause). Participants who receive two doses of PRGN-2009 and go on to receive standard definitive therapy will be evaluable for overall survival assessment.
Secondary	Phase II: 3 Year Relapse-free Survival for PRGN-2009 Alone	3 years	Phase II: 3-year Relapse-free survival assessed using the Kaplan-Meier method, defined as the time from completion of standard of care definitive therapy to the date of disease recurrence or death (any cause) whichever occurs first. Participants who receive two doses of PRGN-2009 and go on to receive standard definitive therapy will be evaluable for overall survival assessment.
Secondary	Phase I: Overall Survival (OS)	The time from the date of first treatment to the date of death (any cause), an average of 12 months	Phase I: Overall survival assessed using the Kaplan-Meier method, defined as the time from the date of first treatment to the date of death (any cause). Participants who are alive at the end of follow up will be censored at the last known date alive.
Secondary	Phase I: Progression-free Survival Time (PFS)	Date of first treatment to date of disease progression or death (any cause), an average of 6 months	PFS, evaluated using Kaplan-Meier methods, defined as the time from the date of first treatment to the date of disease progression or death (any cause) whichever occurs first. Disease progression assessed by the Response Evaluation Criteria in Solid Tumors (RECIST), is defined as at least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). The appearance of one or more new lesions is also considered progression.
Secondary	Phase I: Duration of Response (DOR)	Date of first treatment to date of disease progression or death (any cause), an average of 4 months	Phase 1: DOR is measured from the time measurement criteria are met for Complete Response (CR) or Partial Response (PR) (whichever is first recorded) until the first date that recurrent or progressive disease is objectively documented (taking as reference for progressive disease the smallest measurements recorded since the treatment started). Response was assessed by the Response Evaluation Criteria in Solid Tumors (RECIST). CR is disappearance of all target lesions. PR is at least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum of diameters. Disease progression is at least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). The appearance of one or more new lesions is also considered progression.
Secondary	Phase II: Safety - Number of Treatment-related Serious Adverse Events (AE) of Grades 1, 2, 3, 4 and/or 5 Along With the AE Term	Date treatment consent signed up to 28 days after last treatment	Phase II: Adverse events were assessed by the Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. 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. Grade 1 is mild. Grade 2 is moderate. Grade 3 is severe. Grade 4 is life-threatening. Grade 5 is death related to adverse event. All participants who receive any investigational treatment will be evaluable for safety and toxicity evaluations.
