Phase I/II Study of APS001F With Flucytosine and Maltose in Solid Tumors
A Phase I/II Safety, Pharmacokinetic, and Pharmacodynamic Study of APS001F With Flucytosine and Maltose for the Treatment of Advanced and/or Metastatic Solid Tumors

The purpose of this study is to test the safety and efficacy of an investigational drug called APS001F when given with flucytosine (5-FC) for treatment of solid tumors. APS001F is a recombinant Bifidobacterium longum (a live bacteria normally found in the digestive tract) that has been modified to produce an enzyme, cytosine deaminase (CD). The patient will first receive an injection of APS001F followed by oral 5-FC. APS001F is expected to go to the site of the tumor(s) where the agent will produce CD enzyme. CD enzyme will convert the 5-FC into 5-fluorouracil (5-FU) which is a standard chemotherapy drug for several types of cancer. Additionally, some patients will also receive 10% maltose injection, a sugar that has been shown to enhance the growth and effectiveness of APS001F in animals. This is the first study where APS001F is being used in humans.

Inclusion Criteria:

  1. Patients with advanced and/or metastatic, histologically documented solid tumors.
  2. Patients must have disease that is no longer considered responsive to available conventional modalities or treatments (failed any known standard curative or effective therapy for that disease).
  3. Patients must have measurable or evaluable advanced and/or metastatic disease by RECIST 1.1.
  4. Patients enrolled at Dose Level 6 or higher in the phase I portion of the trial must have at least one tumor mass suitable and easily accessible for excisional biopsy, or alternatively, accessible for CT or ultrasound guided core needle biopsy. The procedure must be able to be performed with minimum morbidity.
  5. ECOG Performance status of 0 or 1.
  6. Must be at least 18 years of age.
  7. Expected survival of at least 3 months.
  8. Men and women of child-bearing potential (i.e., women who are premenopausal or not surgically sterile) must use acceptable contraceptive methods (abstinence, intrauterine device (IUD), oral contraceptive or double barrier device), and women must have a negative serum or urine pregnancy test 1 week before beginning treatment on this trial. Nursing patients are also excluded.
  9. Must be able and willing to give written informed consent.
  10. Patients must have adequate major organ function and meet the following criteria:

    • white blood cell (WBC)count >= 3,000/mm3.
    • Absolute neutrophil count (ANC) >= 1500/uL.
    • Platelets >= 100,000/mm3.
    • Hemoglobin >= 9.0g/dL
    • Serum creatinine <= 1.5 mg/dL. (or estimated creatinine clearance >= 50 ml/min/1.73 m2)
    • Bilirubin <= 1.5 mg/dL; ALT, AST, and alkaline phosphatase <= 1.5x the upper limit of normal
    • Prothrombin Time (PT) and activated partial thromboplastin time (aPTT) <= 1.5x the upper limit of normal.
    • Oxygen saturation >= 90% by pulse oximetry
  11. Patients should have body Temperature <= 38.0 degrees C.
  12. Echocardiogram demonstrated left ventricular ejection fraction >= 40%.

Exclusion Criteria:

  1. Presence or history of brain metastases.
  2. Presence of known or suspected ongoing ischemia of non-tumor tissues including

    • ischemic peripheral vascular disease, myocardial infarction within the past 6 months,
    • congestive heart failure > class II NYHA,
    • unstable angina (anginal symptoms at rest) or new onset angina (i.e., began within the last 3 months).
    • cerebrovascular accident, including transient ischemic attacks within the past 6 months.
  3. An artificial implant that cannot be easily removed (e.g., heart valves, prosthetic hips or knees, or other devices), which could allow a nidus of infection.
  4. Patients with indwelling catheters (other than Portacath, Hickman or PICC lines)
  5. Known cardiac valvular disease (e.g. bicuspid aortic valve) or arterial aneurysm(s) that may allow a nidus of infection.
  6. Known cardiac arrhythmias requiring medication.
  7. Patients with any of the following cardiovascular conditions: patent foramen ovale, prior history of bacterial endocarditis, any existing thrombus (either arterial or venous) as well as known history of DVT, permanent pacemakers, AICDs, LVADs, or other intravascular cardiac device, known AV malformations.
  8. Patients with baseline respiratory insufficiency severe enough to require supplemental oxygen.
  9. Patients with any pleural effusion or abdominal/peritoneal ascites.
  10. Patients with

    • radiotherapy, treatment with cytotoxic agents, or treatment with biologic agents within 4 weeks prior to treatment with APS001F (6 weeks for mitomycin or nitrosoureas).
    • At least 2 weeks must have elapsed from any prior surgery or hormonal therapy.
