  • Localized radiotherapy to 1 or more disease sites is allowed prior to the lymphodepleting chemotherapy, if there are additional measurable non-irradiated disease sites.
  • Eastern Cooperative Oncology Group performance status 0 or 1 (Performance level as measured by Karnofsky for patients > 16 years of age, see Appendix A).
  • Adequate organ function at screening, as defined by the following:
  • Renal: Estimated glomerular filtration rate (Chronic Kidney Disease Epidemiology Collaboration equation) ≥50 ml/min/1.73 m2

  • WOCBP must have a negative urine pregnancy test within 72 hours prior to the start of lymphodepleting chemotherapy. If a WOCBP has a urine pregnancy test that cannot be confirmed as negative, a serum (beta-human chorionic gonadotropin [β-hCG]) pregnancy test will be required.
  • The effects of TROP2 CAR/IL-15 TGFBR2 KO NK cells on the developing human fetus are unknown. Radiation therapy is absolutely contraindicated in pregnant women. For this reason, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. (Refer to Pregnancy Assessment Policy MD Anderson Institutional Policy # CLN1114). This includes all female patients, between the onset of menses (as early as 8 years of age) and 55 years unless the patient presents with an applicable exclusionary factor which may be one of the following:
  • Postmenopausal (no menses in greater than or equal to 12 consecutive months).
  • History of hysterectomy or bilateral salpingo-oophorectomy.
  • Ovarian failure (Follicle Stimulating Hormone and Estradiol in menopausal range, who have received Whole Pelvic Radiation Therapy).
  • History of bilateral tubal ligation or another surgical sterilization procedure.
  • Approved methods of birth control are as follows: Hormonal contraception (i.e. birth control pills, injection, implant, transdermal patch, vaginal ring), Intrauterine device (IUD), Tubal Ligation or hysterectomy, Subject/Partner post vasectomy, Implantable or injectable contraceptives, and condoms plus spermicide. Not engaging in sexual activity for the total duration of the trial and the drug washout period is an acceptable practice; however periodic abstinence, the rhythm method, and the withdrawal method are not acceptable methods of birth control. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately.
  • Male patients treated or enrolled on this protocol must agree to follow the contraceptive guidelines in Appendix 5 prior to study entry and for the duration of study participation and for 6 months post-TROP2 CAR/IL-15 TGFBR2 KO NK cell infusion. Male patients who father a child or suspect that they have fathered a child must immediately notify their doctor.
  • Willing to undergo mandatory blood collections and biopsies as required by the study.
  • Willing to sign consent for long-term follow-up on protocol PA17-0483.
  • Willing to stay within a 2-hour drive (approximately 100-mile radius) of the study site during the first 4 weeks after the TROP2 CAR/IL-15 TGFBR2 KO NK cell infusion.

Who cannot join

  • Patients who meet any of the following criteria will be excluded from study entry:
  • Presence of clinically significant ongoing Grade ≥ 2 toxicity unequivocally associated with the previous anticancer treatment, as determined by the PI. Toxicities related to prior surgery, radiation, prior systemic immune checkpoint inhibitors and chemotherapy should be resolved to Grade 1 or below prior to lymphodepletion.
  • Presence of fungal, bacterial, viral, or other infection requiring IV antimicrobials for management or not responding to appropriate therapy. Note: Patients with simple urinary tract infection and uncomplicated bacterial pharyngitis are permitted if responding to active treatment.

The goal of Part 2 (dose expansion) of this clinical research study is to learn if the dose of TRICK-NK found in Part 1 can help to control the disease.

The optional schedule optimization phase will test a shorter interval between the NK cell infusion and the first dose of T-Dxd.

Read the detailed description

Primary Objective:

To determine the safety, tolerability, maximum tolerated dose (MTD) and administration schedule, and optimal cell dose (OCD) and schedule of CAR.TROP2/IL15-transduced / TGFBR2KO CB-NK cells [TRICK-NK - TROP2-targeted, Reprogrammed with IL-15, CBderived, Knockout (TGFBR2) NK] + T-Dxd, in T-Dxd eligible HER2 positive and HER2 low advanced breast cancers.

Secondary Objectives:

To determine the antitumor activity of TRICK-NK + T-Dxd combination

The intent of offering this treatment is to provide a possible therapeutic benefit and thus, the patient will be carefully monitored for tumor response and symptom relief in addition to safety and tolerability.

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 29 inclusion and 26 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: opening soon, as of the sponsor's last update on 19 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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?

Contact Bora Lim, MD ((713) 745-0689, blim@mdanderson.org), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Safety and Adverse Events (AEs) (time frame: Through study completion; an average of 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 19 Aug 2026.
