A Phase 2 Study to Investigate the Clinical Activity of IPI-504 in Patients With Hormone-resistant Prostate Cancer (IPI-504-04)

December 7, 2012 updated by: Infinity Pharmaceuticals, Inc.

A Phase 2 Open-Label Study to Investigate the Pharmacodynamics and Clinical Activity of IPI-504 in Patients With Castration-Resistant Prostate Cancer Stratified by Prior Chemotherapy

To determine:

  • Anti-tumor activity of IPI-504 in 2 groups of subjects with hormone resistant prostate cancer.
  • Group A - subjects who have not previously received chemotherapy
  • Group B - sujects who have received prior chemotherapy or could not tolerate chemotherapy.
  • Clinical response will be determined by PSA and radiological response

Study Overview

Status

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

IPI-504 is a novel, water-soluble analog of 17-AAG and a potent inhibitor of Hsp90. Hsp90's role in the cell is to control the proper folding, function, and viability of various "client" proteins. Many of these client proteins (such as AKT, Her-2, Bcr-Abl, PDGFR-α, and c-Kit) are oncoproteins or important cell signaling proteins. Inhibition of HSP-90 leads to the proteasomal degradation of these proteins.

In patients with HRPC,there are several proteins that are important in the progression of HRPC, including AR, AKT and Her-2. All of these are client proteins of Hsp90 and in response to Hsp90 inhibition are degraded by their proteasome. Preclinical studies have shown that Hsp90 inhibition causes a dose dependent degradation of these client proteins and growth inhibition of prostate cancer in xenograft tumors.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
