Phase 1 Study Of TROP2 CAR/IL-15 TGFBR2 KO NK Cell In Patients With Oral Premalignant Lesions
United States36 participantsStarted 2026-12-31
Plain-language summary
This is a phase 1, single-arm, open-label, dose-escalation and dose-expansion study designed to evaluate the safety, tolerability, pharmacokinetics (PK), and preliminary efficacy of TGFBR2 TROP2 CAR/IL15 NK cells in patients with high-risk oral premalignant lesions.

Inclusion criteria
. Subjects with diffuse or multifocal oral premalignant lesions are eligible for this study and must have a confirmed histologic diagnosis of oral epithelial dysplasia or oral intraepithelial neoplasia. Diffuse disease is defined as a single lesion measuring 2 cm in greatest dimension, and multifocal disease is defined as the presence of two or more spatially distinct premalignant lesions within the oral cavity. Patients with a history of histologically confirmed head and neck squamous cell carcinoma, including oral cavity squamous cell carcinoma, are eligible provided there is no evidence of active invasive malignancy at the time of enrollment. For patients without a prior history of oral cavity squamous cell carcinoma, eligible lesions must demonstrate high-risk histology, including moderate dysplasia, severe dysplasia, or carcinoma in situ; in patients with a prior history of oral cavity squamous cell carcinoma, dysplasia of any grade identified on prior resection specimens or surveillance biopsies is acceptable. Histologic evidence of oral epithelial dysplasia identified on prior oral cancer resection specimens or surveillance biopsies is acceptable. A visible, clinically measurable oral lesion, such as leukoplakia, erythroplakia, or other clinically apparent premalignant mucosal abnormality, must be present and accessible for intralesional injection and clinical assessment.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

Safety and Adverse Events (AEs)
Timeframe: Through study completion; an average of 1 year
. Patient tumors must demonstrate TROP2 expression of 1+ as determined by IHC at the MDACC CAP and CLIA accredited Clinical Laboratories
. ≥2 weeks from the last cytotoxic chemotherapy, ≥3 days from last TKI or other targeted therapies, and ≥3 months from any cell therapy for any malignancy at the time of consent.
. 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.
. Women of childbearing potential (WOCBP) must have a negative urine pregnancy test within 72 hours prior to initiation of lymphodepleting chemotherapy. If the urine pregnancy test cannot be confirmed as negative, a serum β-hCG test must be performed and must be negative prior to treatment initiation.
. A WOCBP is defined (in Appendix 1) as a female who has experienced menarche (as early as 8 years of age) and has not undergone successful surgical sterilization or is not postmenopausal (defined as ≥12 consecutive months of amenorrhea without an alternative medical cause). Women will be considered not of childbearing potential if they have undergone hysterectomy, bilateral salpingo-oophorectomy, bilateral tubal ligation, or other permanent sterilization procedures, or have ovarian failure with follicle-stimulating hormone (FSH) and estradiol levels in the menopausal range, including those who have received whole pelvic radiation therapy. Due to the unknown effects of TROP2 CAR/IL-15 TGFBR2 KO NK cell therapy on a developing fetus, and because radiation therapy is contraindicated during pregnancy, women of childbearing potential and male participants with partners of childbearing potential must agree to use effective contraception prior to study entry, for the duration of study participation, and for 6 months following TROP2 CAR/IL-15 TGFBR2 KO NK cell injection. Acceptable methods of contraception include hormonal contraceptives (oral, injectable, implantable, transdermal, or vaginal ring), intrauterine devices (IUDs), surgical sterilization (tubal ligation or hysterectomy), partner vasectomy, or barrier methods (e.g., condoms) used with spermicide. Complete abstinence is acceptable if consistent with the participant's lifestyle; however, periodic abstinence, the rhythm method, and withdrawal are not acceptable.
Exclusion criteria
. Pregnant, breastfeeding, or expecting to conceive within the projected duration of the study, starting with the screening visit through 6 months post TROP2 CAR/IL-15 TGFBR2 KO NK cell injection.
. Patients must have recovered from all AEs due to previous therapies to ≤Grade 1 or baseline.
. Patients with ≤Grade 2 neuropathy, alopecia, or other non-relevant AEs may be deemed eligible at the discretion of the principal investigator (PI)/co-PIs. If a patient received major surgery, they must have recovered adequately from the toxicity and/or complications from the intervention prior to the start of lymphodepleting chemotherapy.
. If patients receive RT within 2 weeks of the start of treatment, they must not require corticosteroids and must not have had radiation pneumonitis. Of note, patients with prior RT to the esophagus or with RT plans predicted to expose the esophagus to RT are excluded.
. Has received a live vaccine within 6 weeks prior to TROP2 CAR/IL-15 TGFBR2 KO NK injection and agrees to not receive live vaccine for at least 24 months post-injection. Examples of live vaccines include, but are not limited to, the following: measles, mumps, rubella, varicella/zoster (chicken pox), yellow fever, rabies, Bacillus Calmette-Guérin, and typhoid vaccine. Seasonal influenza and COVID-19 vaccines for injection are generally killed virus vaccines and are allowed; however, intranasal influenza vaccines (e.g., FluMist®) are live attenuated vaccines and are not allowed.
. Prior CAR T or NK cell or other genetically modified T or NK cell therapy.
. Receiving chronic systemic steroid therapy (in doses exceeding 10 mg daily of prednisone equivalent).
. Known active CNS metastases and/or carcinomatous meningitis. Patients with previously treated brain metastases may participate if they completed radiation therapy, are clinically stable, and without requirement of steroid treatment for at least 2 weeks prior to study enrollment.
