Summary

This is phase 2 single arm study evaluating the safety and preliminary efficacy of M-CENK adoptive cell therapy and fixed dose of N-803 in combination with gemcitabine in participants with platinum-resistant high-grade ovarian cancer (HGOC).Up to 20 participants will receive M-CENK (IV) and N-803 (SC) in combination with gemcitabine (IV).

Participants will undergo an apheresis procedure for the collection of mononuclear cells (MNCs) at least 1 day prior to Cycle 1 for manufacturing of M-CENK. Starting in Cycle 1, participants will receive gemcitabine and starting in Cycle 2 they will also receive M-CENK and N-803, until no additional M-CENK is available or confirmed PD per iRECIST, unless the participant is potentially deriving benefit per Investigator's assessment.

Participants who complete the study treatment or discontinue study treatment will be followed for survival/disease status every 12 weeks (± 2 weeks) for up to 12 months after the last study treatment or until death, lost to follow-up, or withdrawal of consent.

Interventions

DRUG

Gemcitabine

Dose: 800 mg/m2 intravenously (IV) Frequency: administered on Day 1, Day 8, and Day 15 of each cycle (every 4 weeks)

BIOLOGICAL

N-803

Dose: fixed dose of 1.2 mg subcutaneously (SC) Frequency: administered on Day 1 and Day 15 of each cycle starting at Cycle 2 (every 4 weeks) and when the last dose of M-CENK is administered, N-803 will be administered on Days 1 and 15 of the same cycle followed by 3 additional doses, 2 weeks apart (total of 5 N-803 doses).

BIOLOGICAL

M-CENK

Dose: 0.15 to 0.75 × 109 cells per infusion intravenously (IV) Frequency: administered on Day 1 of each cycle as long as M-CENK cells are available.
