Brief Summary:

Some tumors are difficult to treat with chemotherapy or radiation. One of the reasons is that areas of the tumor do not have many blood vessels, which makes it difficult for drugs to reach those areas. One way that researchers have recently tried to overcome this problem is by injecting special kinds of bacteria into the tumors. These bacteria have been genetically changed to remove the chemicals that are poisonous to humans, but are still able to cause tumor cells to break down and die. The idea is that these bacteria may be able to assist chemotherapy drugs in fighting cancer.

The goal of this clinical research study is to find the highest tolerable dose of one of these bacterial therapies (Clostridium novyi-NT spores) that can be given in combination with pembrolizumab to patients with advanced solid tumors. The safety of this drug will also be studied, as well as whether it can help to control the disease.

This is an investigational study. Clostridium novyi-NT is not FDA approved or commercially available. It is currently being used for research purposes only. Pembrolizumab is FDA approved for the treatment of melanoma and different types of head and neck and non-small cell lung cancers. It is investigational to use these drugs in combination with each other in various types of advanced cancers.

The study doctor can describe how the study drugs are designed to work.

Up to 18 participants will be enrolled in this study. All will take part at MD Anderson.

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Diagnosis of an advanced solid tumor malignancy. There must be a target tumor which is measureable, palpable or clearly identifiable under ultrasound or radiographic guidance and amenable to percutaneous injection of C. novyi-NT spores. The targeted lesion must have a longest diameter >/= 1 cm and < 12 cm and be measurable as defined by RECIST 1.1 criteria. The target lesion must not be located in either the thoracic, abdominal or pelvic cavities or in the brain. There must be no clinical, no functional, and no radiographic evidence of bone involvement at the site of the target lesion.
  2. History of prior treatment with at least one line of systemic anticancer therapy, when an approved systemic therapy is available, and no curative option is available for continued treatment.
  3. At least 4 weeks have elapsed since the completion of major surgery, and the patient has fully recovered from this surgery and any post-surgical complications.
  4. Patient must have adequate organ function as indicated by the following laboratory values. Hematological: Absolute neutrophil count (ANC) >/=1,500/mcL; Platelets >/=100,000/mcL; Hemoglobin >/=9g/dL or >/= 5.6 mmol/L. Renal: Serum creatinine </= 1.5 X upper limit of normal (ULN. Hepatic: serum total bilirubin </= 1.5 X ULN OR Direct bilirubin </= ULN for patients with total bilirubin levels > 1.5 ULN; AST (SGOT) and ALT (SPGT) </= 2.5 X ULN OR </= 5 X ULN for patients with liver metastases. Coagulation: International Normalized ration (INR) or Prothrombin Time (PT) </= 1.5 X ULN unless patient is receiving anticoagulant therapy as long as PT of PTT is within therapeutic range of intended use of anticoagulants; Activated partial Thromboplastin Time (aPTT) </= 1.5 X ULN unless patient is receiving anticoagulant therapy as long as PT of PTT is within therapeutic range of intended use of anticoagulants.
