Anti-OX40, Cyclophosphamide (CTX) and Radiation in Patients With Progressive Metastatic Prostate Cancer
Metastatic Prostate Cancer
Cancer of the Prostate
Phase 1/Phase 2
This clinical trial will examine a novel combination of anti-OX40 to induce proliferation of
memory and effector T cells in conjunction with cyclophosphamide (CTX) and radiation to
induce tumor antigen release with the overall goal of promoting an immune response against
Ages Eligible: 18 Years

- AST (SGOT) and ALT (SGPT) < 2.5 X upper limit of laboratory normal
- Alkaline phosphatase < 2.5 X upper limit of laboratory normal (If alkaline
phosphatase > 2.5 X upper limit of laboratory normal due to bone metastases,
then patient is eligible.)

least one androgen ablation regimen and docetaxel.Patients who refuse docetaxel
chemotherapy or who are not candidates for docetaxel are eligible to enroll.
6. At least one bone metastatic lesion amenable to radiation
7. Ability to give informed consent and comply with the protocol. Patients with a
history of psychiatric illness must be judged able to understand the investigational
nature of the study and the risks associated with the therapy

continue these medications without change
1. Active infection.
2. Active autoimmune disease.
3. Previous treatment with mouse monoclonal antibodies
4. Need for chronic maintenance oral steroids.
5. Active brain metastatic disease. Patients with treated brain metastases with
surgery, gamma-knife radiosurgery or radiation and stable for at least 4 weeks and
off steroids are eligible.
6. Any medical or psychiatric condition that in the opinion of the PI would preclude
compliance with study procedures.
