What was measured

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 progressive disease (PD) is objectively documented and is evaluated using the Kaplan-Meier method. Response was assessed by the Response Evaluation Criteria in Solid Tumors (RECIST) v1.1. Complete response is disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm. Partial response is at least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum of diameters. Progressive disease 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 progressions.

Analysis population: 1/48 participants in cohort 1 was a screening fail.

Groups in this outcome

Cohort 1, Arm 1: Human Papillomavirus (HPV) Associated Malignancies

Cohort 1, Arm 1, Treatment Assignment Code (TAC) 1: Participants with HPV associated malignancies will receive human papillomavirus (HPV) vaccine every (q) 4 weeks x6, then q3 months (MO) x2 + NHS-IL12 q 4 weeks (wks) + M7824 q 2 wks. PDS0101 will be administered on Day (D)1, D15, D29 followed by booster vaccines every 4 weeks for up to a year. Subcutaneous 1.0mL (2.4mg of total peptide and 3 mg of R-DOTAP (Versamune) injection). M7824 will be administered at a flat dose of 1,200 mg intravenous (IV) (over 1 hour) once every 2 weeks. NHS-IL12 will be administered by subcutaneous (SC) injection every 4 weeks.

Cohort 2, Arm 2: Cervical Cancer With Prior Pelvic Radiation and Boost Brachytherapy

Cohort 2, Arm 2, Treatment Assignment Code (TAC) 1: Participants with cervical cancer with prior pelvic radiation and boost brachytherapy will receive human papillomavirus (HPV) vaccine + NHS-IL12 + M7824 (MSB0011359C) at reduced doses. PDS0101 will be administered on Day (D)1, D15, D29 followed by booster vaccines every 4 weeks for up to a year. Subcutaneous 1.0mL (2.4mg of total peptide and 3 mg of R-DOTAP (Versamune) injection). M7824 will be administered at a flat dose of 1,200 mg intravenous (IV) (over 1 hour) once every 2 weeks. NHS-IL12 will be administered by subcutaneous (SC) injection every 4 weeks.
