Brief Summary
This early phase I trial compares the safety, side effects and the biological or cellular activity of two types of universal donor (UD) natural killer (NK) cells (standard NK cells and transforming growth factor \[TGF\] beta imprinted \[TGF-beta-i\] NK cells), given directly into the tumor (intratumoral) in treating patients with skin (cutaneous) squamous cell carcinoma (SCC) or basal cell carcinoma (BCC). NK cells are a type of white blood cell that can recognize missing or incorrect proteins on tumor cells and then kill these tumor cells. It was recently discovered that infection with human cytomegalovirus (CMV), a common virus, leads to the development of a unique NK cell population. These "adaptive" NK cells have a more potent anti-tumor killing action. The TGF-beta-i NK cells used in this study are created using donors whose blood tests positive for CMV exposure. This may make them more effective at killing tumor cells. Giving UD TGF-beta-i NK cells may be safe, tolerable and/or more effective than standard UD expanded NK cells in treating patients with SCC or BCC.

Outcome Measures
Primary Outcomes (1)
Change in intratumoral natural killer (NK) cell content
Immunohistochemical and in vitro studies of tissue from the original biopsy and post-NK cell treated tumor specimens will be performed to assess NK cell infiltration of the tumor. Difference in NK cell density by CD56 staining in pre- versus post-intervention skin tumor tissue will be compared between tumors receiving NK versus transforming growth factor betai cell injections.
Up to 2 weeks after locoregional injection of NK cells
Secondary Outcomes (1)
Number of participants with treatment-related adverse events as assessed by Common Terminology Criteria for Adverse Events version 5.0 criteria
Up to 8 weeks after biopsy
Study Arms (2)
Cohort I (UD expanded NK cells)
EXPERIMENTALPatients undergo SOC biopsy on day 0 and within 4 weeks (days 10-28) receive UD expanded NK cells intratumorally. Patients undergo SOC excision 4-8 weeks (days 28-56) after biopsy.
Cohort II (UD expanded TGFbetai NK cells)
EXPERIMENTALPatients undergo SOC biopsy on day 0 and within 4 weeks (days 10-28) receive UD expanded TGF-beta-i NK cells intratumorally. Patients undergo SOC excision 4-8 weeks (days 28-56) after biopsy.
Interventions
Undergo SOC biopsy
Given UD expanded NK cells intratumorally
Undergo SOC excision
Given intratumorally
Eligibility Criteria
You may qualify if:
- Ohio State University patients \> 18 years old
- Diagnosis of ≥ 1cm keratinocyte carcinoma, accessible by intra-tumoral injection
- Confirmation of cutaneous SCC (cSCC) (10 patients total) or BCC (10 patients total) via diagnostic biopsy
- BCC: Nodular or aggressive subtype
- SCC: Well-differentiated or aggressive subtype with T1 or T2 staging by American Joint Committee on Cancer (AJCC) criteria
- Patient meets criteria for standard of care surgical treatment with either wide local excision or Moh's surgery
- Presence of residual clinical cancer ≥ 1cm at the time of baseline
- Willingness to follow up for residual cancer extirpation between 2-8 weeks after the injection
You may not qualify if:
- Planned or concurrent radiation or systemic treatment for solid tumor or hematologic malignancy including chemotherapies or immunotherapies received within 6 weeks of trial enrollment. These include but are not limited to methotrexate, 5-fluorouracil, vismodegib, cepilimumab, pembrolizumab, nivolumab, ipilimumab for any skin malignancy
- \< 18 years old
- A negative deep and peripheral margin status from the diagnostic biopsy
- Diagnostic biopsy with the following histopathologic characteristics:
- BCC: Superficial subtype
- SCC: SCC in situ (SCCIS)/Bowen disease, basosquamous, keratoacanthoma (KA)-type SCC, or tumor with \> T2 staging by AJCC criteria
- Any skin disease or active infection in the same area that may confound assessments
- Inability to follow-up for definitive treatment (surgical excision)
- Any other comorbidity or complication that in the opinion of the investigator could make the patient unsafe to participate in the study, such as:
- Active infection
- Pregnant women, women who are likely to become pregnant or are breastfeeding
- Patients who received any other investigational drugs within the 30 days prior to screening visit
