Randomized Phase II Trial of Docetaxel With or Without PSA-TRICOM Vaccine in Patients With Castrate-Resistant Metastatic Prostate Cancer

This randomized phase II trial studies how well docetaxel and prednisone with or without
vaccine therapy works in treating patients with hormone-resistant prostate cancer that has
spread to other parts of the body. Drugs used in chemotherapy, such as docetaxel and
prednisone, work in different ways to stop the growth of tumor cells, either by killing the
cells, by stopping them from dividing, or by stopping them from spreading. Vaccines made
from an antigen may help the body build an effective immune response to kill tumor cells. It
is not yet known whether docetaxel and prednisone are more effective with or without vaccine
therapy in treating prostate cancer.

PRIMARY OBJECTIVES:

I. To evaluate the overall survival in patients treated with PSA-TRICOM (fowlpox-PSA-TRICOM
vaccine and rilimogene-galvacirepvec) and docetaxel chemotherapy versus docetaxel
chemotherapy only.

SECONDARY OBJECTIVES:

I. To evaluate the time to radiographic progression after beginning docetaxel chemotherapy
in patients previously treated with PSA-TRICOM vaccine versus those not treated with this
vaccine.

II. To compare objective responses (according to Response Evaluation Criteria in Solid
Tumors [RECIST]) between the two treatment groups in those patients with measurable disease.

III. To evaluate prostate-specific antigen (PSA) response rates (decline >= 50%) in patients
treated with PSA-TRICOM and docetaxel chemotherapy versus docetaxel chemotherapy only.

IV. To evaluate immune responses elicited in patients treated before and after docetaxel
chemotherapy.

V. To evaluate the association between development of prostate antigen-specific immune
responses and time to progression and overall survival.

VI. To evaluate the association of predicted survival (by Halabi nomogram) with actual
survival in patients treated with PSA-TRICOM vaccine versus those not treated with this
vaccine.

OUTLINE: Patients are randomized to 1 of 2 treatment arms.

ARM A (vaccine and chemotherapy): Patients receive rilimogene-galvacirepvec subcutaneously
(SC) on day 1 of course 1 and fowlpox-PSA-TRICOM vaccine SC on days 15, 29, 43, and 57 of
course 1. Beginning on day 85 (day 1 of course 2), patients receive docetaxel intravenously
(IV) over 1 hour on day 1 and prednisone orally (PO) twice daily (BID) on days 1-21.
Treatment with docetaxel and prednisone repeats every 21 days for up to 12 courses in the
absence of disease progression or unacceptable toxicity.

ARM B (chemotherapy): Patients receive docetaxel IV over 1 hour on day 1 and prednisone PO
BID on days 1-21. Treatment repeats every 21 days for up to 12 courses in the absence of
disease progression or unacceptable toxicity.

After completion of study therapy, patients are followed up every 3 months for 2 years and
then every 6 months for 3 years.

Inclusion Criteria:

- Patient must have histologically confirmed diagnosis of prostate cancer
(adenocarcinoma of the prostate)

- Patient must have metastatic disease as evidenced by the presence of soft tissue
and/or bone metastases on imaging studies (computed tomography [CT] of
abdomen/pelvis, bone scintigraphy)

- Patient must have castrate-resistant disease, defined as follows:

- Patient must have received standard of care androgen deprivation treatment (ADT)
before trial entry (surgical castration versus gonadotropin-releasing hormone
[GnRH] analogue or antagonist treatment); subjects receiving GnRH analogue or
antagonist must continue this treatment throughout the time on this study

- Patient must have been treated previously with a nonsteroidal antiandrogen, with
evidence of subsequent disease progression; subjects must be off use of
anti-androgen for at least 4 weeks (for flutamide) or 6 weeks (for bicalutamide
or nilutamide) prior to randomization; subjects who demonstrate an anti-androgen
withdrawal response, defined as a >= 25% decline in PSA within 4-6 week of
stopping a nonsteroidal antiandrogen are not eligible until the PSA rises above
the nadir observed after antiandrogen withdrawal

- Patient must have castration levels of testosterone (< 50 ng/dL) within 4 weeks
prior to randomization

- Patient must have progressive disease while receiving ADT as defined by any one of
the following as per the Prostate Cancer Clinical Trials Working Group 2 (PCWG2)
criteria:

- PSA: at least two consecutive rises in serum PSA, obtained at a minimum of
1-week intervals, and each value >= 2.0 ng/mL

- Measurable disease: >= 50% increase in the sum of the cross products of all
measurable lesions or the development of new measurable lesions by RECIST
criteria version 1.1; the greatest diameter of a target lesion must be at least
1.0 cm by CT scan (1.5 cm in shortest axis for lymph nodes)

- Non-measurable (bone) disease: the appearance of two or more new areas of uptake
on bone scan consistent with metastatic disease compared to previous imaging
during castration therapy; the increased uptake of pre-existing lesions on bone
scan will not be taken to constitute progression, and ambiguous results must be
confirmed by other imaging modalities (e.g. X-ray, CT or magnetic resonance
imaging [MRI])

- Patient must not have poor prognosis features suggested by the following required
information:

- Presence of visceral (non-lymph node, non-bone) metastases

- Poor performance status (Eastern Cooperative Oncology Group [ECOG] performance
status [PS] of 2 or greater)

- Alkaline phosphatase (IU/L) > 2 x institutional upper limit of normal

- Lactate dehydrogenase (LDH) (U/L) > 2 x institutional upper limit of normal

- Patient must have an ECOG performance status of 0 or 1

- White blood cell (WBC) count >= 2000/mm^3

- Absolute neutrophil count (ANC) >= 1500/mm^3

- Platelet count >= 100,000/mm^3

- Creatinine =< 2.0 mg/dL

- Aspartate aminotransferase (AST), alanine aminotransferase (ALT) =< 1.5 x
institutional upper limit of normal (ULN)

- Total bilirubin < institutional upper limit of normal (ULN)
