What was measured

DOR per treatment assignment (three or four drug combination) 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 measured by the Response Evaluation Criteria in Solid Tumors (RECIST) v1.1. 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.

Analysis population: 1/32 participants were evaluable for this outcome measure.

Groups in this outcome

Cohort 1, Arm 1 Triple Therapy Without NHS-IL12 (M9241)

Carcinoembryonic antigen (CEA)/ Mucin 1 (MUC1) Vaccines + (M7824 (MSB0011359C) + N-803 (Anktiva) (Triple Therapy). CV301: CV301 vaccine consists of modified vaccinia Ankara (MVA)-BN-CV301 and Fowlpox (FPV)-CV301). MVA-BN-CV301 (4 x 10\^8 infectious units/0.5 mL each) will be administered as four subcutaneous (SC) injections on Day (D)1 and D15. Starting on D29, FPV-CV301 (1 x 10\^9 infectious units/ 0.5mL) will be administered as a single subcutaneous injection every 4 weeks on Arm 1 or every 6 weeks on Arm 2A and 2B for up to one year. MSB0011359C: Participants will receive M7824 via intravenous (IV) infusion over 1 hour (-10 minutes / +20 minutes, that is, over 50 to 80 minutes) once every 2 weeks. M7824 will be administered as a "flat" dose of 1,200 mg or 300 mg independent of body weight. M7824 is administered as an intravenous infusion with a mandatory 0.2 micron in-line filter. N-803: N-803 will be given via subcutaneous injection at a dose of 15 mcg/kg every four weeks on Arm 1. N-803 will be administered at as dose of 10 (Micro)g/kg by SC injection every 4 weeks on Arm 2A and Arm 2B.
