The study consists of 2 parts: Part A is a randomized, multiple-dose, double-blind, placebo-controlled sequential dose escalation study to evaluate GS-6624 in subjects with Idiopathic Pulmonary Fibrosis (IPF) and was completed in October 2011.

Part B is a randomized, two-dose, open-label dose expansion study to evaluate GS-6624 in subjects with IPF and is currently enrolling.

Further study details as provided by Gilead Sciences:

Primary Outcome Measures:
  • To characterize the safety, tolerability, and pharmacokinetics (PK) of GS-6624 [ Time Frame: 113 days ]
    To characterize the safety, tolerability, and pharmacokinetics (PK) of GS-6624 after multiple intravenous (IV) administrations in subjects with idiopathic pulmonary fibrosis (IPF).

Secondary Outcome Measures:
  • - To evaluate the formation of anti-GS-6624 antibodies. - To assess the effects of GS-6624 treatment on force vital capacity (FVC) and carbon dioxide diffusing capacity (DLCO) - To assess the effects of GS-6624 treatment on SGRQ [ Time Frame: 113 Days ]

    Secondary Endpoints:

    • Anti-GS-6624 antibody formation;
    • Change in FVC and DLCO;
    • Change in SGRQ score.

Enrollment: 48
Study Start Date: December 2010
Study Completion Date: December 2012
Primary Completion Date: December 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: GS-6624 125mg Drug: GS-6624
Patients will be treated with GS-6624 (125 or 200 mg) administered IV over 1 hour on specific days during the treatment period.
Other Name: AB0024
Experimental: Experimental: GS-6624 200mg Drug: GS-6624
Patients will be treated with GS-6624 (125 or 200 mg) administered IV over 1 hour on specific days during the treatment period.
Other Name: AB0024

Detailed Description:

The primary objective of this study is to characterize the safety, tolerability, and PK of GS-6624 after multiple IV administrations in patients with IPF. The secondary objectives are to evaluate the formation of anti-GS-6624 antibodies and to measure the effects of GS-6624 on FVC, DLCO, and SGRQ score. A total of 48 patients will be enrolled. In the double-blind phase (Part A), a total of 18 patients were enrolled at 3 dose levels. Part A was completed in October 2011.

In Part B, 30 patients will be enrolled at 2 dose levels. Part B is open-label and is currently enrolling.
