About
To find the recommended dose of an investigational therapy called chimeric antigen receptor (CAR).TROP2/interleukin (IL)15-transduced TGFBR2 KO cord blood (CB)-derived natural killer (NK) cells (TROP2 CAR/IL-15 TGFBR2 KO NK cells) that can be given with and without preconditioning radiation therapy in patients with advanced head and neck squamous cell carcinoma.
Full description
Primary Objective:
To determine the safety, tolerability, and recommended Phase 2 dose (RP2D) of chimeric antigen receptor (CAR).TROP2/interleukin (IL)15-transduced TGFBR2 KO cord blood (CB)-derived natural killer (NK) cells (TROP2 CAR/IL-15 TGFBR2 KO NK cells) combined with and without preconditioning RT in patients with advanced head and neck squamous cell carcinoma.
Secondary Objectives:
- To determine the antitumor activity of TROP2 CAR/IL-15 TGFBR2 KO NK cells, including those with pre-CAR-NK bridging SBRT in patients eligible to receive this. Although the clinical benefit of TG TROP2 CAR/IL-15 TGFBR2 KO NK cells has not yet been established (and is currently being investigated in other solid tumors in other clinical trials we have rendered), 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. Efficacy will be determined in each cohort, and for this, we will have a pre-planned subset analysis of patients with metastatic disease where one site is not irradiated.
- To quantify the persistence of infused allogeneic donor CAR-transduced CB-derived NK cells in the peripheral blood of the recipient.
- To conduct comprehensive immune modulation studies by evaluating tissue and bloodbased biomarkers associated with response and resistance to TROP2 CAR/IL-15 TGFBR2 KO NK cell infusion.
- To obtain preliminary data on quality of life and patient experience.
- To evaluate longitudinal changes in circulating tumor DNA (ctDNA).
Exploratory Objectives:
- In patients who do not receive SBRT due to ineligibility, they are still eligible to receive CAR-NK cell therapy. This inadvertent biologic randomization may enable cross-sectional comparison of outcomes and correlatives among the patients who receive RT vs. not.
- To quantify the progression-free survival, overall survival, and the duration of responses of TGFBR2 KO CAR.TROP2/IL15-transduced CB-derived NK cells combined with preconditioning RT in patients with advanced head and neck squamous cell carcinoma.

Inclusion and exclusion criteria
Inclusion Criteria:
Patients with histologically confirmed head and neck cancer, either HPV+ or HPV-, that is locally advanced AND unresectable OR metastatic (≤5 sites of disease), which has relapsed or progressed following local standard treatments that are known to prolong survival, or for which no standard treatment is available or are no longer effective, or refused such therapy.
Patient tumors must demonstrate TROP2 expression of 2+ or 3+ as determined by IHC at the MDACC CAP and CLIA accredited Clinical Laboratories.
- 2 weeks from the last cytotoxic chemotherapy at the time of lymphodepleting chemotherapy; ≥3 days from last TKI or other targeted therapies at the time of lymphodepleting chemotherapy; ≥3 months from any cell therapy for any malignancy at the time of lymphodepleting chemotherapy; prior radiation therapy is allowed at the time of consent.
RT allowed to ≥1 disease sites prior to the lymphodepleting chemotherapy. If there are additional measurable non-irradiated disease sites, this may be evaluated for response as well. If multiple lesions are irradiated, we advise that a single lesion will be treated to a higher dose and other lesions considered for lower doses, and that one site always remain unirradiated if a patient has ≥2 sites of disease.
Age ≥18 years. Because no dosing or adverse event data are currently available on the use of TROP2 CAR/IL-15 TGFBR2 KO NK cells in combination with radiation therapy in patients <18 years of age, children are excluded from this study.
Patients must have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
Life expectancy ≥3 months per PI or treating physician's discretion.
A female patient is eligible to participate if at least one of the following conditions applies:
a. Not a woman of childbearing potential (WOCBP). OR
A WOCBP who agrees to follow the contraceptive guidelines in Appendix 5 during the study treatment period and for 6 months post-TROP2 CAR/IL-15 TGFBR2 KO NK cell infusion.
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 [B-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.
A female patient who becomes pregnant, or suspects pregnancy while she or her partner is participating in this study, must immediately notify her doctor. Female patients who become pregnant will be taken off study.
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.
