Brief summary: In this Phase 1 Trial investigators plan to establish the MTD of HyperAcute®-Renal (HAR) immunotherapy in subjects with clinically metastatic renal cell carcinoma.

Detailed description: Unfortunately, despite the best clinical efforts with surgical intervention and chemotherapy many patients with high grade and advanced stage renal cell carcinoma (RCC) progress and die of their disease. In United States approximately 13,000 individuals die from RCC each year. The primary cause of failure is microscopic spread of the tumor prior to complete surgical extirpation of detectable disease and the heterogenous nature of the metastatic cells. These cells are resistant to all forms of therapy including chemotherapy, radiation, and escape from immune surveillance by a variety of mechanism. This results in low 5-year survival rates (approximately 10%) in patients with metastasis. Novel immunotherapeutic strategies provide a hope in circumventing the drug resistant RCC and improve the survival of patients undergoing surgery. RCC, like melanoma is one of the most immunogenic tumors and partial successes have been achieved by a variety of immunotherapeutic strategies show partial successes. Although vaccines have been highlighted in clinical trials since the mid-1970s with subcutaneous autologous irradiated tumor cells most of these studies were in patients with advanced disease. These approaches resulted in rare if any clinically relevant benefits to patients. However, new vaccines in other cancers have shown responses equivalent to chemotherapy with minimal toxicity \[1\]. The use of immune adjuvant strategies to increase the therapeutic immune responses to tumor vaccines enhanced the proportion of patients with therapeutic responses to vaccination to 10%-15% on average. Only during the last decade has it become clear that failure of immune system to respond to the tumor vaccine is the main obstacle that limits the efficacy of vaccine based immunotherapies. The precise reason for failure of the immune system in cancers is very complex particularly as it relates to (1) the escape of growing or metastasizing tumor from immune surveillance \[2-4\] and (2) low immunogenicity of autoantigens associated with malignant neoplasms. This human clinical trial will investigate the dose limiting toxicity of a polyvalent immune enhanced vaccine as a first step towards developing a multipronged approach to triggering the immune system to attack and destroy micrometastatic disease. Investigators hypothesize that the allogeneic RCC cell genetically modified to express α (1,3)galactosyltransferase (enzyme responsible for producing the strong xenoantigen on the cell surface of the cellular immunotherapy) will augment the efficacy of cellular immunotherapy and thereby improve patient outcomes. In this Phase 1 Trial investigators plan to establish the maximum tolerated dose (MTD) of Hyperacute®-Renal (HAR) immunotherapy in subjects with clinically metastatic renal cell carcinoma.

Eligibility criteria: Inclusion Criteria:

* pT3, G any, N1; or, pT4, G any, N1; or, pT any, G any, N1 or M1)
* Subjects have already undergone all standard of care surgery appropriate for stage of disease.
* Eastern Cooperative Oncology Group (ECOG) Performance Status ≤2.
* Serum albumin ≥3.0 gm/dL.
* Adequate organ function including:

  1. Marrow: Hemoglobin ≥10.0 gm/dL, absolute granulocyte count (AGC) ≥1,000/mm3, platelets ≥75,000/mm3, absolute lymphocyte count ≥475/mm3.
  2. Hepatic: Serum total bilirubin ≤2.5 x upper limit of normal (ULN), ALT (SGPT) and AST (SGOT) ≤2.5 x ULN.
  3. Renal: Serum creatinine (sCr) ≤ 2.0 x upper limit of normal.
* Patients must have the ability to understand the study, its risks, side effects, potential benefits and be able to give written informed consent to participate. Patients may not be consented by a durable power of attorney (DPA).
* Male and female subjects of child producing potential must agree to use contraception or avoidance of pregnancy measures while enrolled on study and receiving the experimental drug, and for one month after the last immunization.
* Patients who have received previous systemic therapies including TKI inhibitors are eligible.

Exclusion Criteria:

* Age \<18-years-old.
* Active CNS metastases or carcinomatous meningitis. Patients with CNS lesions that have been treated and who have no evidence of progression in the brain on CT/MRI for ≥1 month are eligible.
* Pregnant or nursing women due to the unknown effects of immunization on the developing fetus or newborn infant.
* Other malignancy within five years, except that the following may be eligible:
* patients curatively treated for localized squamous or basal cell carcinoma of the skin or for carcinoma in situ of the uterine cervix (CIN) or breast,
* Patients with a history of malignant tumor who have been disease free for at least five years and are not currently being treated.
* History of an allogeneic solid organ transplant or bone marrow transplant, or current active immunosuppressive therapy such as cyclosporine, tacrolimus, etc.
* Subjects taking systemic (parentally or orally) corticosteroid therapy for any reason, including replacement therapy for hypoadrenalism, are not eligible. Topical steroids are acceptable as are intranasal steroids.
* Active infection or antibiotics within 48 hours prior to study enrollment, including unexplained fever (temp \> 38.1°C), if deemed clinically significant by the treating physician.
* Evidence of active autoimmune disease (e.g., systemic lupus erythematosis, rheumatoid arthritis, with the exception of vitiligo. Patients with a remote history of asthma or mild asthma are eligible.
* Other serious medical conditions that may be expected to limit life expectancy to less than 1 year (e.g., liver cirrhosis).
* Any condition, psychiatric or otherwise, that would preclude informed consent, consistent follow-up or compliance with any aspect of the study (e.g., untreated schizophrenia or other significant cognitive impairment, etc).
* Patients having previously undergone splenectomy.
* Patients with known hepatitis or unstable liver disease, and/or positive serologies for Hepatitis B or C and HIV.
* Patients with sickle-cell anemia or thalassemia major.
* History of any one or more of the following cardiovascular conditions within the past 6 months:

  * Cardiac angioplasty or stenting
  * Myocardial infarction
  * Unstable angina
  * Coronary artery bypass graft surgery
  * Symptomatic peripheral vascular disease
  * History of Class III or IV congestive heart failure, as defined by the New York Heart Association Classification of Congestive Heart Failure
  * History of cerebrovascular accident including transient ischemic attack (TIA), pulmonary embolism or untreated deep venous thrombosis (DVT) within the past 6 months.
* Any serious and/or unstable pre-existing medical, psychiatric, or other condition that could interfere with subject's safety, provision of informed consent, or compliance to study procedures
* Concurrent investigational therapy given to treat cancer or concurrent participation in another clinical trial involving anti-cancer investigational drug.
* Administration of an investigational drug within 30 days or 5 half-lives, whichever is longer, preceding the first dose of study treatment.
