Background:

Some people with prostate cancer have a rise in prostate-specific antigen (PSA). This can happen even after treatments like radiation and surgery. Androgen deprivation therapy (ADT) drugs and close monitoring are one standard way to treat this group of people. Another way is to monitor people and their PSA values over time. Researchers want to see if a combination of new drugs can help these people.

Objective:

To see if the combination treatment of PROSTVAC, CV301, and MSB0011359C (M7824) can induce an anti-tumor attack in people with biochemically recurrent prostate cancer.

Eligibility:

People ages 18 and older with certain kinds of prostate cancer

Design:

Participants will be screened with

-Medical history

-Physical exam

-Blood and urine tests

-A scan of the neck, chest, abdomen, and pelvis

-A bone scan

A sample of tissue that was already taken will be tested. This will confirm the diagnosis, stage, and disease status.

Some participants will have close monitoring with four monthly PSA checks.

All participants will get two study drugs as shots under the skin. They will get the third drug in a vein. They will get the drugs over at least 7 months. Their vital signs will be checked before they get the drugs and for up to 1 hour after.

Participants will have frequent study visits. They will have physical exams, urine and blood tests, and scans.

Participants will return to the clinic about 4 weeks after they stop taking the study drugs. They will have a medical history, physical exam, and blood tests. They may also have long-term follow-up visits.

Eligibility

INCLUSION CRITERIA:

-Histopathological documentation of prostate cancer confirmed in either the Laboratory of Pathology at the National Institutes of Health (NIH) Clinical Center, or Walter Reed National Military Medical Center prior to enrollment. If no pathologic specimen is available, participants may enroll with a pathologist s report showing a histologic diagnosis of prostate cancer and a clinical course consistent with the disease.

-Recovery to baseline from acute toxicity related to prior therapy, including surgery and radiation. (28 days removed from last systemic therapy, 14 days removed from last radiation therapy).

-Hepatic function eligibility parameters (within 16 days before starting therapy):

--Bilirubin less than or equal to ULN (OR in participants with Gilbert s syndrome, a total bilirubin less than or equal to 3.0), AST and ALT less than or equal to 1.5 times upper limit of normal.

-Adequate renal function defined by an estimated creatinine clearance > 50 mL/min according to the Cockcroft-Gault formula or by measure of creatinine clearance from 24 hour urine collection.

-No other active malignancies within the past 36 months (with the exception of nonmelanoma skin cancers or carcinoma in situ of the bladder) or life-threatening illnesses.

-Willing to travel to the NIH for follow-up visits.

-18 years of age or older.

-Able to understand and sign informed consent.

-The effects Prostvac and CV301 on the developing human fetus are unknown. For this reason, men must agree to use highly effective contraception (that is, methods with a failure rate of less than 1% per year) prior to study entry, for the duration of study therapy and at least four months after the last treatment administration. Should a woman become pregnant or suspect she is pregnant while her partner is participating in this study, she should inform her treating physician immediately.

-Additional Inclusion Criteria Specific to Safety Lead-In Cohort

--Castrate testosterone level (<50ng/dl or 1.7nmol /L)

--Progressive disease at study entry defined as one or more of the following criteria occurring in the setting of castrate levels of testosterone:

---Radiographic progression defined as any new or enlarging bone lesions or growing lymph node disease, consistent with prostate cancer

OR

---PSA progression defined by sequence of rising values separated by >1 week (2 separate increasing values over a minimum of 2ng/ml (PCWG2 PSA eligibility criteria). If participants had been on flutamide, PSA progression is documented 4 weeks or more after withdrawal. For participants on bicalutamide or nilutamide disease progression is documented 6 or more weeks after withdrawal.

--Participants must agree to continuation of androgen deprivation therapy (ADT) with a gonadotropin-releasing hormone agonist/antagonist or bilateral orchiectomy

---ECOG performance status of 0-2 (Karnofsky >80%).

---Hematological eligibility parameters (within 16 days before starting therapy):

---Granulocyte count greater than or equal to 1000/mm^3

---Platelet count greater than or equal to 100 000/mm^3

---Hgb greater than or equal to 9 g/dL

---PT less than or equal to 1.5 x ULN

---aPTT less than or equal to 1.5 x ULN

Additional Inclusion Criteria Specific to Biochemical Recurrence Cohort

-Biochemical progression defined as follows:

--For participants following definitive radiation therapy: a rise in PSA of greater than or equal to 2 ng/mL above the nadir (per RTOG-ASTRO consensus criteria)

--For participants following radical prostatectomy: rising PSA after surgical procedure (participants must have a PSA greater than or equal to 0.8 ng/mL)

-Participants must have a rising PSA as confirmed by 3 values a minimum of 1 week apart over at least a 1 month period of time.

-Participants must have a PSA doubling time of 5-15 months.

-ECOG performance status of 0-1 (Karnofsky greater than or equal to 80%).

-Negative CT scan/MRI and bone scan for metastatic prostate cancer.

-Baseline testosterone greater than or equal to 100 ng/dl.

-PSA less than or equal to 30 ng/mL.

-Hematological eligibility parameters (within 16 days before starting therapy):

---Granulocyte count greater than or equal to 1000/mm3

---Platelet count greater than or equal to 100 000/mm3

---Hgb greater than or equal to 10 g/dL

EXCLUSION CRITERIA:

-Immunocompromised status due to:

--Human immunodeficiency virus (HIV) positivity.

--Active autoimmune diseases such as Addison's disease, Hashimoto's thyroiditis, systemic lupus erythematosus, Sjogren syndrome, scleroderma, myasthenia gravis, Goodpasture syndrome or active Grave's disease.

---Participants with a history of autoimmunity that has not required systemic immunosuppressive therapy or does not threaten vital organ function including CNS, heart, lungs, kidneys, skin, and GI tract will be allowed.
