Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The study is divided into two parts. In Part A of the study, cohorts of subjects will be administered escalating doses of ORCA-010, using the 3+3 design. When the Maximum Tolerated Dose has been determined in Part A, a group of 12 new subjects will be treated in Part B of the study at this dose, with two administrations separated by a 2-week interval.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Safety profile of ORCA-010
Time Frame: 365 days
To evaluate safety and tolerability of intratumoral administration of ORCA-010 according to CTCAE V5.0. The primary endpoint of this study is to assess Dose Limiting Toxicities (DLTs) and the Maximum Tolerated Dose (MTD) for ORCA-010 to determine the final safety dose of administration for Phase IIa/Part B.
365 days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Biological activity of ORCA-010
Time Frame: 365 days
To explore the biological activity of intratumoral administration of ORCA-010. Biological activity of ORCA-010 will be measured by assessing viral replication by measuring ORCA-010 virus DNA in blood. In addition, virus replication and spread will be assessed by staining prostate cancer tissue obtained through prostate biopsies with adenovirus specific antibodies. Subject's serum will be assayed for antibody responses against ORCA-010.
365 days
Antitumor immune responses
Time Frame: 365 days

To evaluate potential antitumor immune responses following ORCA-010 administration. Subject's serum will be analyzed for antibody responses against tumor-associated antigens (e.g. PSA, PSMA, PCA3, and Prostein). Subject's Peripheral Blood Mononuclear Cells (PBMCs) will also be analyzed for cellular immune responses against tumor-associated antigens.

Prostate biopsies will be taken to detect local antitumor immunological reactions (eg. infiltration and activation of T cells).
365 days
Shedding of ORCA-010
Time Frame: 365 days
Shedding of ORCA-010 will be assessed by detection of vector DNA in blood and urine using quantitative-PCR (Q-PCR).
365 days
