This study is a first in human Phase 1 study that involves patients with a type of cancer called HER2 (Human Epidermal Growth Factor Receptor 2) positive cancer.
This study asks patients to volunteer to take part in a research study investigating the safety and efficacy of using special immune cells called HER2 chimeric antigen receptor specific cytotoxic T lymphocytes (HER2 specific CAR T cells), in combination with intra-tumor injection of CAdVEC, an oncolytic adenovirus that is designed to help the immune system including HER2 specific CAR T cell react to the tumor.
The study is looking at combining these two treatments together, because we think that the combination of treatments will work better than each treatment alone. We also hope to learn the best dose level of the treatments and whether or not it is safe to use them together.
In this study, CAdVEC will be injected into participants tumor at one tumor site which is most easiest to reach. Once it infects the cancer cells, activation of the immune response will occur so it can attack and kill cancer cells. (This approach may have limited effects on the other tumor sites that have not received the oncolytic virus injection, so, patients will also receive specific T cells following the intratumor CAdVEC injection.) These T cells are special infection-fighting blood cells that can kill cells infected with viruses and tumor cells.
Investigators want to see if these cells can survive in the blood and affect the tumor. Both CAdVEC and HER2-specific autologous CAR T are investigational products. They are not approved by the FDA.

Experimental: Treatment Phase
Seven dose levels will be evaluated using the BOIN design. Cohorts of size 3 will be enrolled at each dose level until 9 evaluable patients have been studied at a single dose. Each patient will receive an intratumoral injection of CAdVEC alone or combined with an injection of HER2.CAR.T cells 3 days later (Day 4), according to the following dose levels. Dose Level 1 CAdVEC = 5.00E+9 HER2 specific CAR-T cells = 0 Dose Level 2 CAdVEC = 1.00E+10 HER2 specific CAR-T cells = 0 Dose Level 3 CAdVEC = 1.00E+10 HER2 specific CAR-T cells = 1.00E+06 Dose Level 4 CAdVEC = 1.00E+11 HER2 specific CAR-T cells = 1.00E+06 Dose Level 5 CAdVEC = 1.00E+11 HER2 specific CAR-T cells = 1.00E+07 Dose Level 6 CAdVEC = 1.00E+12 HER2 specific CAR-T cells = 1.00E+07 Dose Level 7 CAdVEC = 1.00E+12 HER2 specific CAR-T cells = 1.00E+08 |
Biological: CAdVEC
The intratumoral administration of CAdVEC will create a pro-inflammatory tumor microenvironment and will promote the recruitment and expansion of adoptively transferred HER2 specific CAR T cells via CAR (tumor antigen). We expect HER2 CAR T cells expanded at primary tumor sites will re-circulate and target metastasized tumors. The combination we propose to test has the potential to overcome each of the established individual limitations of oncolytic viruses and of CAR T-cells. Testing each element separately would not be beneficial or informative, since the combination therapy is anticipated to have unique profiles of both therapeutic benefit and potential toxicities.

- Number of patients with dose limiting toxicity (DLT) by CTCAE 5.0 [ Time Frame: 6 weeks after the HER2.CAR AdVST infusion or 6 weeks + 3 days after the CAdVEC injection. ]Incidence of dose limiting toxicities (DLT) of CAdVEC intratumoral injection in combination with HER2.CAR AdVST cells in patients with advanced refractory HER2 positive solid tumors.
- Overall Response Rate (ORR) according to RECIST1.1 criteria [ Time Frame: 13 weeks ]Overall response rate is defined as the number of patients experiencing PR or better (i.e. PR + CR) divided by the number evaluable for efficacy. Tumor regression or progression will be evaluated accordingly with RECIST 1.1 criteria.
- Disease Control Rate (DCR) [ Time Frame: 13 weeks ]Disease Control Rate is defined as as the number of patients experiencing SD or better (i.e. SD+PR+CR) divided by the number evaluable for efficacy. Tumor regression or progression will be evaluated accordingly with RECIST 1.1 criteria.
- Progression Free Survival (PFS) [ Time Frame: 15 years ]Progression-Free Survival is defined as the time from start of treatment to disease progression or death.
- Overall Survival (OS) [ Time Frame: 15 years ]Overall survival is defined as the time from the start of treatment to death due to any cause.

Ages Eligible for Study: | 18 Years and older (Adult, Older Adult) |
Sexes Eligible for Study: | All |

Inclusion Criteria:
This study will look at solid tumors (as a basket trial for any solid cancer) with HER2 positivity based on IHC
- Histologically confirmed advanced refractory HER2 positive solid tumors, including but not limited to: head and neck squamous cell carcinoma; cancer of the salivary glands; lung cancer; breast cancer; bladder cancer; gastric cancer; esophageal cancer; colorectal cancer; and pancreatic adenocarcinoma. HER2 positivity is defined as ≥2+ staining by IHC with either the FDA-approved CB11 antibody (Leica) or anti HER2/neu (4B5) (VENTANA), which refers to greater than weak-to-moderate staining intensity in >10% tumor cells (HER2 positivity requirement is excluded in DL1 and DL2 as HER2 targeted agents are not used).
- The disease must be deemed unsuitable for curative treatments including surgery, radiotherapy, systemic therapy, including checkpoint inhibitors, or any combination of the above modalities by the referring oncology physician and confirmed by the senior oncologists leading the protocol.
- Disease must have progressed after standard first line therapy, or without available effective treatment options. Patients are still eligible if they have failed more than one line of therapy.
- The patient must have at least one tumor site appropriate for intratumoral injection.
- The patient must have radiographically measurable disease as per RECIST 1.1.
-
The patient must have adequate organ function within 7 days prior to treatment as indicated by following measures:
- Hematologic: Absolute neutrophil count (ANC) ≥1.0 x 109/l; Hemoglobin ≥7 g/dl; Platelet count ≥ 100 x 109/l; PT or PTT ≤ 1.5 x ULN unless the subject is receiving anticoagulation.
- Hepatic function: bilirubin < 2 x ULN, and AST and ALT < 3 x ULN
- Renal Function: serum creatinine <2 x the ULN or creatinine clearance >60 mL/min.
- Prior HER2 targeted therapy is allowed if delivered at least 4 weeks prior to the enrollment. (Excluding DL1 and DL2)
- Eastern Cooperative Oncology Group (ECOG) performance status 2 or less (Appendix I).
- Females of childbearing potential must have a negative pregnancy test and agree to use contraception during on-study protocol therapy, or deemed to be not able to get pregnant.
- Male subjects with pregnant partner/female partner of childbearing potential agree to use barrier contraceptive during the study to minimize the risk of embryo-fetal exposure.

This does not include stable, previously-treated brain metastases. Patients on DL1 and DL2 can continue prior checkpoint inhibitors and HER2 targeted agents during the DLT evaluation period.
- Patients at significant risk of airway compromise or other critical obstruction (e.g. bowel, ureter, etc.) in the event of possible post injection tumor inflammation based on the investigative team's judgement.
- History or evidence of active autoimmune disease requiring continuous systemic corticosteroids, immunosuppressants or other disease modifying agents.
-
