Trial Information

An Open-Label, Phase I Dose Escalation Trial of MVA-BN®-PRO in Men With Androgen-Insensitive Prostate Cancer


MVA-BN®-PRO is a candidate prostate cancer immunotherapy product comprised of a highly
attenuated non-replicating vaccinia virus, MVA-BN®, engineered to encode prostate specific
antigen (PSA) and prostate acid phosphatase (PAP) proteins. The MVA-BN®-based vaccine
provides innate and adaptive immune activating factors, and vaccination by this strategy
will be evaluated for its capacity to help override self and tumor tolerance mechanisms.

Previous work has shown PSA and PAP antigens to be immunogenic in humans when presented with
immune stimulatory components. Multiple clinical studies have demonstrated promising
activity of PSA-targeted vaccinia-based immunotherapy. Additionally, PAP-based cellular
therapy immunization approaches, have shown promise in Phase III clinical trials and
provided for enhanced survival. The strategy undertaken by BNIT is to combine both antigens
in the MVA-BN® vector to enhance the immunogenic effect and to help mitigate development of
tumor resistance.

This trial examines three vaccination regimens of MVA-BN®-PRO:

Vaccine is provided at (0.5cc/dose/1x10e8 TCID50)

- Cohort 1: 1 sc injection every 4 weeks x 3; retreated once at the same dose and
schedule.

- Cohort 2: 2 sc injections every 4 weeks x 3; retreated once at the same dose and
schedule.

- Cohort 3: 4 sc injections every 4 weeks x 3; retreated once at the same dose and
schedule.

These dose regimens are based on the current dose of MVA-BN® (1x10e8 TCID50 by sc injection)
under development as a prophylactic vaccine for the prevention of smallpox, and on related
clinical studies of MVA-nef-based vaccines (5x10e8 TCID50) for induction of heterologous
immunity.


Inclusion Criteria:



- Signed Informed Consent

- Men, 18 - 75 years of age

- Documented prostate cancer with a rising PSA post androgen suppression or blockade
therapy

- Chemotherapy naïve

- ECOG Performance Score of 0,1, or 2

- Life expectancy ≥ 1 year

- No significant cardiac, bone marrow, hepatic, or renal dysfunction; or coagulopathy
(defined as no AE ≥ Grade 3 according to NCI CTCAE v 3.0). Patients with a known
history of a CLINICALLY NON-SIGNIFICANT laboratory parameter may be eligible for
inclusion provided an exemption is granted by the study Medical Monitor prior to
enrollment.

- A negative virology screen for HIV, hepatitis B surface antigen, and hepatitis C

Exclusion Criteria:

- Metastatic disease

- Congestive heart failure (NYHA Class III or IV), unstable angina, or cardiovascular
disease such as stroke or myocardial infarction (current or within the past 6 months)

- History of prior malignancies other than prostate cancer within the past 5 years,
excluding basal or squamous cell carcinoma of the skin

- Known allergy to eggs, egg products, or aminoglycoside antibiotics, e.g., gentamicin
or tobramycin

- Chronic administration (defined as 5 or more days of consecutive use) of systemic
corticosteroids within 14 days of the first planned dose of MVA-BN®-PRO. Use of
inhaled steroids, nasal sprays, eye drops and topical creams for small body areas is
allowed.

- History of or active autoimmune disease. Persons with vitiligo or thyroid disease
taking thyroid replacement hormones are not excluded.

- Prior solid organ or hematopoietic allogenic transplant(s)

- Receipt of an investigational agent within 28 days of the first planned dose of
MVA-BN®-PRO

- Prior "vaccine" therapy for prostate cancer at any time

- Vaccination: Live (attenuated) vaccine (e.g., FluMist®). Vaccination with a live
vaccine within 28 days of the first planned dose of MVA-BN®-PRO, or plans to receive
a live vaccine within 28 days after the last dose of MVA-BN®-PRO is not allowed

- Vaccination: Killed (inactivated) vaccine (e.g., PneumoVax®). Vaccination with a
killed vaccine within 14 days of the first planned dose of MVA-BN®-PRO, or plans to
receive a killed vaccine within 14 days after the last dose of MVA-BN®-PRO is not
allowed.

- Radiation therapy within 28 days of the first planned dose of MVA-BN®-PRO or plans
for radiation therapy during treatment or re-treatment. Prior to initiating
palliative radiation during the (re)treatment phase of the study, the Sponsor's
medical monitor or designee must be notified.

- Any condition which, in the opinion of the investigator, would prevent full
participation in this trial (including the long-term follow-up), or would interfere
with the evaluation of the trial endpoints
