  1. 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).
  2. 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.
  3. 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.
  4. The patient must have at least one tumor site appropriate for intratumoral injection.
  5. The patient must have radiographically measurable disease as per RECIST 1.1.
  6. 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 ≥9 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.

5. Study Description

Brief Summary
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.
Detailed Description
Treatment with CAdVEC: On the first day of your treatment, participants will receive an injection of CAdVEC into your tumor. A blood sample will be obtained from the participant before the CAdVEC intratumor injection . Depending on the location of the tumor, different techniques can be used for the injection into your tumor. The most common route of injection is ultrasound-guided percutaneous (needle puncture in the skin) injection, but endoscopic (using a lighted, flexible instrument called an endoscope) ultrasound-guidance will be used for some patients as appropriate. Prior to percutaneous injection, participants may receive an anti-anxiety medicine to calm them down, to relieve muscle spasms, and provide sedation. If the participants tumor is injected during an endoscopic procedure, the procedure may be done under sedation. Treatment with HER2- specific autologous T Cells: Earlier the participant gave blood for us to make HER2 targeting cytotoxic T-lymphocytes (HER2- specific autologous T Cells). These cells are grown in the lab and frozen for participants. Invesitgators made the cells by combining dendritic cells (DCs) or monocytes with the T cells in the presence of produced mixtures of adenoviral proteins. Investigators then put a new gene in to those T cells to make them specifically attract to and kill HER2 positive tumors. As the T cells grow, they are cultured by adding adenoviral proteins for stimulation and expansion. Investigators call those T cells: HER2- targeting T cells (HER2- specific autologous T Cells). This study looks at different doses of HER2- specific autologous T Cells. The decision about the dose participants receive is determined when enrolled on the study. Seven dose levels will be evaluated. 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. CAdVEC intratumoral injection will be given as a single injection to a single appropriate tumor site by direct, endoscopic, or image-guided injection on Day 1. HER2.CAR T cells will be given intravenously on day 4 after CAdVEC injection, with a 3 day window (until day 7). Before receiving the T cell infusion, participants may be given Benadryl (diphenhydramine) and Tylenol (acetaminophen). Tylenol and Benadryl are given to prevent a possible allergic reaction to the T cell administration. Standard medical tests before treatment: Before being treated, participants will receive a series of standard medical tests and procedures as well as research blood draws. Standard Medical tests during and after treatment: During treatment, participants will receive standard medical tests and procedures as well as research blood draws. Study specific evaluations: Investigators will follow participants closely after treatment for any side effects for at least 2 years after the last infusion. To learn more about the way the T cells are working in the body, an extra blood sample will be taken before the CAdVEC injection, before the CAR T cell infusion, and at week 1, 2, 4 , 6, months 3, 6, 9 and 12 after CAR T cell infusion. Thereafter every 6 months up to 5 years and then yearly for 15 years. Investigators will use this blood to see how long the T cells last and to look at the immune response to the cancer. Investigators may also obtain a tumor tissue biopsy before CAdVEC injection, between days 5 and 10 after infusion of the HER-2 CAR-T cells, and at the time tumor recurs. Urine will be collected before CAdVEC injection, Days 2, 4 (or the day of CAR T-cell infusion), weeks 1 and 2 after CAR T cell infusion.

Intervention Name(s)

Other Intervention Name(s)
HER2-specificCAR- T
Intervention Description
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.
