About this study

Official title: Phase 1 Open-Label Study of Autologous M-CENK in Subjects With Locally Advanced or Metastatic Solid Tumors

This is a two-part, open-label phase 1 study to evaluate safety and preliminary efficacy of M-CENK Suspension for Infusion, Cryopreserved, and N-803 for subcutaneous administration in subjects with locally advanced or metastatic solid tumors. The study consists of two cohorts: cohort 1 includes subjects with either newly diagnosed solid tumors who have not received prior therapy or subjects who have received prior first line treatment; and cohort 2 that includes subjects with relapsed/refractory (r/r) solid tumors who have progressive disease after receiving ≥ 2 prior therapies. The two cohorts will be conducted simultaneously.

Read the detailed description

Both cohorts will be enrolled simultaneously. Both cohorts have a part A (apheresis) and cohort 2 has a part B (M-CENK treatment [one bag has a 100 mL cell suspension containing 0.25 to 0.75 x 109 cells] and N-803 treatment).

Up to 40 subjects may be enrolled in cohort 1. Subjects in cohort 1 will participate in apheresis collection of MNCs prior to receiving disease specific first-line therapy per primary oncologists' recommendations. Subjects who have completed apheresis in cohort 1 may subsequently enroll in cohort 2 part B if they have progressive disease after ≥ 2 prior therapies or if they have progressive disease within 12 months of receiving neoadjuvant or adjuvant chemotherapy.

They must also meet the inclusion criteria to participate in the treatment phase (cohort 2 part B). Additionally, all subjects will be re-evaluated to confirm that they still meet the specified eligibility criteria once the M-CENK cells are manufactured and prior to the first administration of M-CENK. The Sponsor will approve the subject's continued eligibility prior to receiving the manufactured M-CENK cells.

Up to 21 subjects may be enrolled in cohort 2 part A so that up to 11 subjects receive at least 1 dose of M-CENK. A dose is a single administration of M-CENK cells or a single administration of N-803. Subjects in cohort 2 part A will undergo an apheresis collection of MNCs prior to receiving approximately 4 weeks of disease-specific therapy per oncologists' recommendations while the M-CENK cells are being manufactured for use in the treatment phase (cohort 2 part B). Subjects will be evaluated for eligibility in inclusion/exclusion criteria prior to enrollment into part B. Additionally, all subjects will be re-evaluated to confirm that they still meet the specified eligibility criteria once the M-CENK cells are manufactured and prior to the first administration of M-CENK. The Sponsor will approve the subject's continued eligibility prior to receiving the manufactured M-CENK cells.

M-CENK cells, manufactured from the autologous apheresis product, may be administered up to 10 times weekly starting on study day 1 with a minimum of 7 days between each M-CENK dose depending on the availability of cells and that there is no contra-indication to administer cells. Subjects will receive up to 5 doses of N-803 SC every 2 weeks prior to every other dose of M-CENK (ie, odd number M-CENK doses).The treatment may be administered for up to 10 doses of M-CENK, if the subject tolerates treatment, the doses of M-CENK cells are available, and the Investigator believes there may be potential benefit to the subject.

Safety endpoints include assessments of TEAEs, SAEs, and clinically significant changes in safety laboratory tests, and vital signs. Toxicities will be graded using CTCAE Version 5.0, or in the case of CRS, using a specified grading system. Safety will be monitored throughout the study.

The treatment of the initial 3 subjects in cohort 2 part B will be staggered with at least a 2-week interval between each subject. After the first 3 subjects in cohort 2 part B are treated, the treatment of existing subjects in cohort 2 part B will be paused after the 14-day toxicity assessment period for a safety evaluation by the Safety Review Committee (SRC). Based on the SRC safety evaluation, the treatment of the subsequent subjects can proceed if the safety evaluation from the initial 3 subjects in part B suggests that the therapy is safe. There will be another safety review after all subjects in cohort 2 have completed the 14-day toxicity assessment period.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing M-CENK, Suspension for Infusion, Cryopreserved (M-CENK) (Cohort 2 part B), N-803 (Cohort 2 part B) and Apheresis collection of MNCs (part A) in people with Metastatic Solid Tumor, run by ImmunityBio, Inc. at 2 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 33 inclusion and 28 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 2 Nov 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Primary Objective (cohort 1 and cohort 2, part A subjects): Determine the safety of mononuclear cell (MNC) apheresis collection by the number of treatment-emergent adverse events (TEAEs) and serious adverse events (SAEs) related to apheresis. (time frame: Study Day 1, assessed for up to 1 week). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04898543.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Nov 2026.
